There are several ways ‘distance’ impacts a design. The physical distance is essentially scaled to human body measures and work capacities. The sensorial measure of the space is the reach in space. All these, help us to equate the suitability and adequacy of spaces for different purposes.

The distance, refers to a physical measure, a separation, and perception of proximity or remoteness from an extraneous location.

1 Measure Between

2 Separation

3 Perception

A physical space has filler elements like, people, objects and environmental affectations. These elements have their own sizes and also have medial spaces. The scale of the physical space, and the relationships between objects-objects, people-people and objects-people, are factored by the distance.

ONE      We measure the space in terms of distances, at realistic level, between ‘us’ and things (A to B). Inversely, we also measure the space for the perceived (likely) distance (B to A) between things and ‘us’. The objective (A to B) and subjective (B to A) assessments, together, provide a comprehensive experience of the space. The spatial experience is a maze of relationships and directions. But a constant reference is provided by the Environmental affectations that mark the time and movement. The environmental affectations cause many aberrations of perception of spatial distances and relationships, due to the mix up of the actual and perceived distances. We can exploit such changes to project or contract our presence in a space.

TWO    When the perceiver is a separator, if somewhere between the two ends, or objects. Distance comparisons ensue, to find out the disparities. The physical distance on either of the sides defines the nearness or remoteness of a thing in space. It helps to know which one is available, useful, required size, intensity, etc. Such distance assessment is often personal and comparative as it depends on reach capacity, need, experience and group behaviour dynamics.

THREE    Observing anything in space from an external location, the distance is realized as the degree of clarity. The clarity is governed by physical distance from the location of observation. The same distance, however, gets occluded by the intervening activities (chaos, noise, echoes, bounce-back, reflections, disturbances and intermingling of effects) and the environment (fog, smoke, dust). But these also offer a referential spatial scale. The field of perception increases or decreases with the mediating distance.

Temporal distance refers to distance in time. Something that is temporally close is something that is near in time, whereas something that is temporally distant is far in time. Temporal distance to imagined future events modulates our evaluative representation of them. The greater the distance, the more likely the event is to be conceptualized in terms of a few abstract features. This is relevant in case of potential dangers or risks because this mechanism cognitively separates us from the reality of likely undesirable eventualities.

Psychologists from Walter Mischel to Nira Liberman and Yaacov Trope have labelled the psychological distance: that is, gaps between you and other people social distance, the present and the future temporal distance, your physical location and faraway places –spatial distance, or imagining something and experiencing it -experiential distance.

When psychological distance is large, we tend to think in more-abstract terms, focussing on the big picture, the desirability of certain options, and why we want them. In contrast, when psychological distance is small, our thinking is more concrete: We focus on the details, the feasibility of options, and how we will use them -Rebecca Hamilton https://hbr.org/2015/03/bridging-psychological-distance

12 TERMS for DISTANCES

Distancing is a prime mechanism of offense and defence when methods and means of survival are inadequate, or unavailable. The distance operates at real level, as realized by us, and also as we feel the opponent is perceiving it. Shortening the distance serves an offensive role and enhancing the reach, a defensive purpose. The spatial depth is affected by the separation through occlusion or camouflage. It helps in fuzzing the identity and recognition.

Anything that lies in ‘front’ (of sensorial nodes -eyes, nose, ears) is always at a ‘shorter distance’, compared to askew encounters, which have ‘greater distance’ (straight, up or down level exchanges). Short distance leads to possible physical contact with intimacy and often breach of privacy. Long distanced contact offers wider space for other actions including time for escape.

14 41d480458ab16799aa1f

The distance, direction and angle of eye contact affect the intimacy and so privacy. Executives want broad and deep tables to ‘keep the distance’ with the visitors. At a meeting or on a dining table, the chief occupies end-position, and with that no one can take frontal confronting stand.

15 21378548110_bb1d7fca8a_z

Any position against a static and closer backdrop is more assuring, then a backdrop whose depth cannot be fathomed. And for the same reason activities on the backside (stage, podium, office table, information kiosk, reception tables) are not desirable. In a space, one looks for anchorage in the presence of people (even, if unknown), architectonic elements, objects and opaque surfaces. Fixed and familiar things in space, even if physically distanced are better as support. Similarly the location and direction of an exit (door or any other egress point), or a path to it, at whatever the distance, are preferred.

7831251790_d39bd1c43d_z

For an individual, a space segment that allows one to control the distance from others is a safe, predictable and reassuring territory. Here the occupants and objects have intense relevance to each other. In interpersonal relationships the distance delineates isolation, accessibility, domination, submission, agreement, dissension, insulation, engagement, etc.

16 640px-Minding_ones_own_business_(38097651011)

The distance and space, both form the notions of Intimacy and Privacy. One physically manipulates, or sensorially perceives the distance from other beings and objects. The sense of vision, hearing, smelling are dependent on the distance. but touch and taste.

17 25893976046_a99e2e33f4_z

Intimacy is also a biological need, as it relies on compatibility, sexual needs, glandular secretions, social acceptability, etc. It is an attitude, mental conditioning or mental posture. Intimacy could be one-way feeling that is without reciprocal response. Intimacy is not always a function of physical proximity. One can feel close to a person who is long dead -an illusory presence or through notional links (clothes, odours, recorded sounds, etc.).

Distance Etymology > Distaunce (13-14 C) =a dispute, controversy, civil strife, rebellion, disagreement, discord, strife. Destance (Old French) =discord, quarrel. Distantia (Latin) =a standing apart. Distantem (nominative distans) = standing apart, separate, distant. Distare =stand apart, from the root ‘sta’ =to stand, make or be firm. Modern Distance =remoteness of space, extent of space between two objects or places, an interval of time (originally distaunce of times).=remote part of a field of vision.

DYNAMIC CURVATURES -Issues of Design 24

Post 684–by Gautam Shah

13 Barcelone - Detail of a Gaudi building

A curvature is the synergetic dynamism of a line and the external forces, unlike a straight line which is the path of a force. Antonio Gaudi stated that ‘The straight line belongs to the man, the curve to God.’ All curvatures on earth manifest under two basic forces, the gravity of the earth and the current stresses resetting the earlier status. The curvature reflects the forces, form and ensuing functions. But Dynamic curvature is a live story, telling us How a form changes under stress. Dynamic curvatures are found in spiral coils, serpents, water ripples, plasticity of wet clays, free movements of flying birds, bending of bamboos, sand-dunes, clouds, etc.

A line occurs across two things. As per Euclid’s definition ‘The extremities of a line are points’. A ‘line’ in literary sense, had no distinction, It needed an appendage ‘straight or curved’. In this sense a curve is a generalization (stressed or stress-free?) of a line. Historically, the term ‘line’ (perhaps from linen, lino or flex) was used for, rope, hawser, series, row, rule, direction, rope, flaxen cords, thread, cable etc. -many indicating curved forms of line. The difference between a line and curve is of scale.

Curvatures and Streamlined products 1930-1940s

Curvature, in mathematics, is the rate of change of direction of a curve with respect to distance along the curve. At every point on a circle, the curvature is the reciprocal of the radius. For other curves (and straight lines can be regarded as circles of infinite radius), the curvature is the reciprocal of the radius of the circle that most closely conforms to the curve at the given point’.

Over a longer distance, all lines are parallel or meeting in infinity. The earthly spatial geometry has latitudes as the parallel lines but longitudes converge at poles. Latitude and longitude both at smaller scale are ‘straight’ otherwise curved. Such spatial geometry lines are implied, but their curvatures are real and experience-able. A line, Earth’s horizon is seemingly straight, but in reality a curvature. A plane travels between two points, in shortest and a straight path, but following the curvature of the earth’s surface, an implied line.

A line is a connection, where the intrinsic transfer of energy makes it straight, but extrinsic or abutting energy deforms it to a curved line. All types of energy transfers are revealed in the direction. Lines and curves with substance get stressed due to their own weight, and yield to the gravity. Materials yield or resist tolerable deformation. Such visual flections also occur over short distances. Our eye visually bends a straight line, and so facade of the Parthenon required several calibrations. In reality the tops of the towers of a suspension bridge or transmission pylons are further apart than at the bottom, due to a curved surface of the earth.

There are many different forms of line. The transition from one to another medium reveals as an angular bent. Water-submerged section of a stick is a visual aberration of a line. Crystals are molecular level entities with the linear-angular structure. If the same are formed over a curved surface such as a liquid droplet, the crystals take the shape of the surface. Gravity has a tendency to distort the way crystals form. Outer space with nearly zero gravity allows creation of complex, three-dimensional proteins. Here the gravity and convective forces do not interfere in crystal formation. It is always advised to aim ‘higher’ to let the ‘bent’ trajectory reach the spot. So nature has both, the lines and curves, the former as intrinsic, and later as the extrinsic effects of forces.

Curvatures, like the lines, also have a direction, as measured for the angle of the straight line formed by connecting any two points on the curvature. Such a presumed line could have horizontal, vertical or inclined angle, with reference to the earth. Curves that have a known or mechanical method of origin are Geometric, but if irregular or complex and cannot be defined using any equations, are Phantomastic.

Curved lines come back to their point of origin to form a closed or determinate form (circle, ellipse). Closed curves have no beginning or end, but could be spiral, where the ends merge but in some other time or space. But, it could go to infinity to form an open or indeterminate entity, losing the essence of the curvature to a parabola, and eventually become a straight line.

Circles have easier sense of movement, but spirals give a sense of completeness, but without any restrain. Spirals are natural shapes in shells, snails, water-whirls, cyclone or tornado. Spirals are boundless and open, going to outward or inward eternity. Spirals arrive back, but bring in positional and temporal change. Spirals represent the notion of growth, evolution and often confusion. Spirals move in clockwise of anticlockwise directions, that perhaps the persistence of initiating and sustaining energy. A spiral as a curve represents time, metaphorically better then lines do. A spiral curve is not a closing circle, but turns around to arrive back at a different elevation (or position). Essences of spiral are the pull and push, and both are linear. Structurally a spiral is linear entity for compression-tension. So spiral, a curve, is a line.

Curves with a single stroke can have one bridging line passing over any two pints on it, but multi-strokes curves can have as many bridging lines. Single stroke curve, create forms open on a single side, with an area asset on one side of it. Multi-stroke curves, on the other hand, create alternating open side form area assets that alternate on either side of it.21 Optical,_Corrections_in_Architecture_95

Silhouette, outline, skyline, horizon, shadows or contour lines, are all edge lines of real or ephemeral entities. The silhouettes are accumulative projection of several objects. The outlines define extremity of an object, if strong, subdue the object by framing and limiting its extent. Skylines are the human formations, a unique horizon-impression of the urban scape. A horizon is an ephemeral line between the sky and terrain. Shadows follow the object but occluding the details of the object-body. Contour lines are curvilinear, unless of man-made mass like roads and trenches. Borders demarcate the domain differences in terms of social, political, beliefs, but usually reinforced by the terrain. Borders are linear dividers or closed ended protectorates (if, squared framed or full curved forms).

The Lines start and terminate to a point, whereas the Curvatures have uncertainty about their ends. Lines as edges of angular planes show cleaved faces (diamonds, crystals), but curves of a streamlined product have ‘continuity’.

A streamlined shape lowers the friction drag in the medium it moves, air or water. Drag is a force that slows down movement. Many animals, birds, and machines, such as aeroplanes, trains and submarines, have streamlined bodies to reduce friction drag’.

During the Great Depression of the 1930s America had new style of Art-Deco architecture (late), product and graphic design. The Streamline Moderne or Art Moderne, favoured the curvilinear edges, accompanied by horizontal lines (parallel to gravity rather then up against it). Industrial designers stripped the Art-Deco design ornaments to implement the aerodynamic design. Long ribbon windows and cylindrical forms were new vocabulary of the ultramodern. All consumer products such as clocks, radios, telephones, cars, furniture, and other white good appliances were redefined to fit in the new concept. But these were sought to be replaced with modern materials of the age, steel, concrete and glass, and these had angular traditions.

SIZING and SCALING the SPACES -Issues of Design 23

Post 674 –by Gautam Shah

.

42500611662_1cc1e0dd5b_z

Sizing of architectural entities is accomplished in Three manners. 1, as a primary reference, the sizes are perceived in human measures, 2, in a second consideration, the sizes mean physical capacities of human body representing the work capacities, physical reach and sensorial reach of perception, and 3, lastly the sizes are mutually related for proportioning, irrespective of the human relevance.

38376493136_42b277d231_z

In the 1st case, the sizes are relative to the human measures, and these had formed the first set of scales in all cultures. The innate reference to the human measures survived, in spite of the standardization to overcome the racial-anthropological variations and cultural preferences. Digitized measures of Metric system completely abstracted the measures, and absolute alienation occurred.

640px-CrystalCathedral

For the 2nd example, the sizes reflect the physical capacities of the body and sensorial reach of perception. Typically, for very long time travel distances were expressed in time, required for walking or running (or number of lunch-rest, feed for horses, required). Wheat and other agricultural products were transacted by numbers or volume capacities like bushel or basket. Displacement (carriage) of goods was in terms of oxen or horse power. Architecturally a wall was measured in terms of (volume x distance) displacement of stones rather than the volumetric measure of the finished structure. The ‘culture of measures was complicated by fractioning or multiplying the ‘measures’ for conversion to the abstract entity like money.

640px-Tarazona_-_Vista

With 3rd instance, the sizes are perceived to be pure numbers. The pure numbers have some basic linear ascending or descending sequences. This character is difficult to understand or justify, and ‘too dry or latent’ to be meaningful. But, it has a mathematical confirmation across many sensorial experiences and presence of physical objects. The mathematical order, however is a confirmation or satiation that occurs after the creation, and is rarely an input for planning.

Tate.modern.interior.london.arp

The sizes are considered as pure numbers to ‘apportion’ physical objects or sensorial experiences, as large, small or equal. Such apportioning of the physical objects or sensorial experiences is intentional or comes as a revelation. But it is an achievement that offers certain applicable aesthetic relationships. Corbusier in his Modulor compared the sizes with pure numbers, and derived a universally applicable set of aesthetic relationships. Vitruvius remained, with the mutual comparison of (human) sizes, but yet had some aesthetic derivations.

 

29275214436_24f866ba61_z

Sizes are mutually related as functional or accommodative operants, or are considered as pure numbers with ‘mathematical’ sense, and a comparison ensues. The relationship is basically between ‘this and that’. Here both the entities are physically in the same realm, of identical sensorial realization, or one of it is in a different time or space. In the last case the remembrances or records bring forth the proportions. Proportioning is ordering of an arrangement. It follows some analogy, sequencing, proximity or context. There are two levels of proportions: formed between equals and unequals. Equal entities, even if spread over extensive area, begin to ‘loop in the coexisting things’ into a holistic domain. Unequal things must be contextually together to make a ‘sense of being a system’.

21600552642_07b8f6e18e_z

When a space is Sized or dwelled, it confers certain functionality and sufficiency. Comparison is made out in terms of ergonomic suitability and sensorial adequacy. But when a space is Scaled, it forms a comparative order between various constituents. Sizing a space specifies, the nature of cognition, human reach, nature of communication and inverse affectations. The levels of privacy, intimacy, loss of objectivity and subjective involvements that occur in a space, are governed by its size. Scaling a space, offers means of perpetuating the satisfaction that one draws out of natural, created or realized things. Scattered elements manifest may reveal, some day the order of scaling or pattern of arrangement. This is an intellectual confirmation.

Size has a close affinity to the orientation of ‘lay’ of the space. The direction of smaller or larger size gives a feel of a deep and shallow space. The orientation gains relevance because it is aligned with our sensorial nodes. The sensorial nodes are highly directional whereas the bi-nodal faculties like eyes and ears help the focussing. Similarly with the sense of direction we perceive the change in speed. The variations in progress and movement both define the ‘lay’ of the space. This experience is true for deaf and blind persons.

nyc_newyorkcity_people_blackandwhite_bw_white_newyork_black-241602.jpg!d

Scale is perceived irrespective of the measure, being simply relationship between numbers. To read a measure one must read the object in ‘ortho’ mode (straight, upright, right, correct). A projection system used in maps, architecture etc. where the rays are parallel. So the scaling or proportion system works, but can it work in a perspective mode? A building can have three major planes simultaneously perceptible, but affected by the visual foreshortening. Can the scaled relationships remain valid in perspective perception?

14758932096_db2c84eb00_z

schmuela_-_more_sun_and_shadows

Measurement scaling, from mathematical series, Vitruvian or Corbusier’s Modulor systems were created for built forms and products. At a similar level musical scales and recitation metres have been defined. But can these musical scales and recitation metres be transposed to other scenarios like architecture? Conversely can anyone create musical composition with Corbusier’s Modulor system or use literary recitation metres for building design? Often numerical values are assigned to various types of data like opinions, judgements, and concepts, are these numbers amenable to scaling, and provide any rationale.

Musical_Fountain_Kolkata

Functionality and the Environment are difficult to separate, as one seems to manifest the other. Spaces within the known range (of recognition) are predictable and so manageable. So strangeness or alienation of spaces is reduced by introducing elements that form a scale. Such scaling elements also serve other purposes like repetitions, rhythmic evolution, structured patterning, sensory gradation, acceleration-de-acceleration, graduated changeovers, linkages, etc. Such scaling elements also occur naturally, like shadows. In architecture orthographic sciography the relationship is of 45°.

Drawing,_Elevation_of_a_Wall_Monument,_1780

Scaling is a perception of relationships that are not just visual but involving all sensorial faculties. So when due to the environmental conditions or personal sensorial deficiencies, the sense of scaling may get fogged but for only one or few and not all faculties.

MODELLING of OBJECTS in SPACE -issues of design -20

Post 662 -by Gautam Shah

.

Objects in space, like architectural features, architectonic elements, furniture, furnishings and often occupants, are all moderated by scaling, positioning, contextual setting, distancing angling and sensorial attributes. In modern sense modelling is considered to be gestural and postural positioning of static or dynamic nature where, ‘dressed or configured’ entities and regulated surroundings enact an intended effect.

From_behind_the_Diwan-I-Aam_(Fatehpur_Sikri,_Agra)

For a designer the purpose of modelling is to expose objects in a controlled manner. The controlled manner is either obvious or discreet. For a designer modelling offers individual recognition, inter-group relationships, comparison with others, signification and indication.

539px-Palazzo_Te_Mantova_2

For modelling all sensorial faculties are stimulated, but visual perception followed by aural and tactile senses are extensively used. Modelling is also considered as the representation of an ‘additional dimension’ in a ‘two-dimensional image’, or revelation of additional information.

Lascaux_04

Modelling is a term closer to cartooning or cartoon making of the middle ages. Artists used to prepare full size replica-images of objects (trees, furniture, architectural elements) and common figures (saints, gods, angels, grotesque-forms) on starched fabric, paper or parchments, for tracing them out in murals and paintings. These were often leased out to others. But, most important modelling processes that of highlighting the form was not explored here.

Henry Moore Double Oval

Modelling at a very simplistic level has been used as a tool for highlighting individual objects by creating contrasting background, emphasizing the silhouette or by delineating the outer most edge with heavier line. Modelling by scaling is also much used method. Here important objects, story line actors or events are represented in larger scale, frontal position or on higher elevation, centric or perspective a focal point, or with brilliant detailing.

Modernism Concrete Le Corbusier India Ahmedabad

Important features of architecture were emphasized by designing illumination sources like openings and reflective planes. Le Corbusier always used reflective ceilings, walls or curvilinear planes (inside faces of cones, drums) against openings. These not only marked the opening emphatically but created a self-sustaining model. The same techniques were used in paintings. Henry Moore has in his sculptures explored the voids for modelling. Fashion shows for apparel are conducted on long raised walkways that offers bottom-up views for the connoisseurs, but few are inclined for ground level walkways, but rarely for zigzag movements. The later proposal makes it difficult for ‘modelling’.

Fashion Shows

Stage performance shows have audience exposure from limited range of angle, and modelling for such static position events are not very difficult. Media shows and soap-operas require very different norms of object modelling. The purpose of modelling is the view captured through the camera. There are multiple cameras with static or moving stations, different capacities of zooming and depth-width of field; all these need to be instantly fulfilled. But the illumination, positioning, depth, highlights etc. cannot be changed for each shot or frame, rather remains consistent. Instead online editing soft tools are used for the required modelling effects. Studio news casts are very fixed events, and so modelling remains equally static. To add life, live scene merging, morphing, voice-over, scene mixing etc. is used, but with poor results.

Architectural modelling was a style of presentation or a manner of expression through surrogate like scaled model or drawings. But architects have been subtly or explicitly involved in ‘forming’ their work as an intended impression. The designed entity is made to fit in the existential conditions or the interventions (like landscape) stretch beyond the nominal domain. It has many parallels in Art.

Marina Hotel Dubai

Architectural modelling has three basic approaches. At one level the observer moves around an object, for different tasks, in variable environmental conditions, and at varying distances and angles. At another level the objects shift (including other occupants) for the stationary observer. And in some circumstances the observer and observed entity both switch their positions.

geodesic-dome-1050336_640

Objects are scaled larger then functionally required (e.g. gates and door portals are large, but functional shutters are smaller). Objects are framed by larger but enclosing forms to emphasize smaller entities. Strategically placed openings not only capture a view, but are positioned as an object in the interior space. Top-heavy objects like shading devices, or bottom-heavy objects like pedestals, top-light entities like steeples, and bottom light stilted structures like gazebos or canopies were historical examples, but the language continues. In every building there are few points where modelling is obvious, like entrances, exits, stairs, escalators, receptions. Similarly some large areas like atrium, lobbies, passages, foyers, halls that need elemental modelling to divide-spread attention on multiple focuses. Distancing and angling are explored in public spaces like railway stations, airports, plazas etc. where spaces have multiple height connections.

Volga-Don Canal

Modelling of static objects, where the observer moves around it, is comparatively easy due to the fewer dynamics. First strategy could be to restrict the distance, angle, speed and range of movements of the observers. Second way could be to restrict the schedule of exposure and take advantage of sunlight. Third approach may regulate the encounter by suitable framing and occlusion. Fourth system involves designing a set of experiences to precondition the observer.

Modelling La_ola,_Jorge_Oteiza

In real life experiences we see the architectural entity and the user-beholder, both as dynamic set. We encounter such things, at real level in rides of amusement parks, trains, buses, plazas, planes, helicopters etc. and in hyper reality of games, training consoles, non-invasive medical instruments etc.

Holographic-3d-avatar

Opening systems like windows, skylights, clerestories provide the necessary natural luminescence (brightness or intensity) to show the form, colour and texture of spatial objects. Objects are perceived mainly due to the direction of light and its ever-changing nature. These are often enhanced, contrasted or subdued by reflectance and also by artificial illumination. The size and intensity of the luminescence determine the shadow density and so affect the ‘modelling’.

Sun and shadows Wikipedia Image by Karen Green

The first traces of the word modelling derives from French modelle or modèle, Italian modello or Latin modellus or modulus, as something made to scale, manner or measure architect’s set of designs, likeness made to scale, measure, standard (from root> med -to take appropriate measures). The sense to showcase or display garments or fashion design is comparatively recent’.

SPACE IDENTIFIERS

Post 656 -by Gautam Shah

Clock Tower Croatia Adriatic Sea Dubrovnik Old TownA space is a recognized and improvised, or a designed configuration for a range of behaviour. The layperson recognizes and improvises, and the expert designs it, but can only surmise how it will manifest. The stack holders are often not aware of the basis of the recognition, improvisation or design. Yet everyone does arrive at common realization.

Very vast exterior spaces are recognized for the markings that indicate sensorial ‘effects’. Other exterior spaces are finite, shaped and sized by bounding elements. Neighbourhood spaces are known through their bounding elements, which could be natural, and exploited or improvised. Spaces for inhabitation require greater degree of intervention then improvisation, and so are designed as enclosures.

Markings are evident through physical elements like: edges, banks, thresholds, slopes, plains or fences and environmental effects thereon. We perceive only certain range of space. The reach varies with perceiver’s capacity, needs and environmental conditions, so is very circumstantial. The behaviour with reference to markings is perfunctory as it relates to the potential –what can one do with it ? A wild exterior space defined by the markings is an infinite realm.

630px-Edward_S._Curtis,_Canyon_de_Chelly,_Navajo,_1904

Bounding elements are definitions that dimension, grade, scale and proportion a space. These define the change like a drop in terrain, contour, variation colour or texture, illuminated or shaded objects, etc. The bounding elements indicate the purpose of the space, and in many cases even the nature of its ownership and structure of administration. Such elements restrict the perception or environmental effects. Neighbourhood spaces have recognizable geometric order or a predictable configuration, purposive locations for anchorage, well-defined zones, distinct routes and paths, good visibility (and other clarity of other sensorial perception) and recognition of the whole and its parts. The depth or scale of the space is defined by the sensorial reach of users, such as vision, hearing, smelling, touches etc.

Enclosures, man-made or natural, are very evident from the change in environment they cause. The enclosures, like shell, roofs, coverings, awnings, curtains, partitions, ceilings etc. create a dimensional space. A space created by an enclosure is far more enduring then one defined by the bounding. A very strong enclosure creates an isolated space, with very limited relevance. However, translucency of the enclosure allows exchanges. Enclosures become vibrant through transgressions, as extrusive encroachment or intrusive yielding. It creates a wide variety of purposive settings.

The virtual immediacy, of the interior and the exterior realms is like an antithetic zone to the other. It is also achieved by carrying across the impressions of the other.

A space segment, a wild exterior with markings, a neighbourhood with bounding elements or an enclosure, cannot become a setting for habitation, till further sub-zoned into locations for various tasks and identified with the environmental qualities.

SPACE PERCEPTION -through seeing, hearing and touching

Post 630 –by Gautam Shah

.

Space perception is realization based on three faculties of Perceptions, namely seeing, hearing and touching. First two of these are bi-nodal, and allow us to perceive an extra dimension of the space, whereas touch is multi-focal, but operates as local sense. The information is received through spatially separated sensors, but complex neural integration allows the three to be perceived in mutually balancing experience. Absence or deficiencies of one or few are substantially overcome through such assimilation. These sensorial experiences (seeing, hearing and touch) persist in a space for a while, and so prolong and reinforce the experience. The experience persists, when the main happening is active, through the fading period, and after the expiry of the original causation.

Space perception is a process of becoming aware of the relative positions of the own-self, surrounding objects, and environmental effects. Sense of near-far, distance, orientation, datum, are part of space perception. Space perception of objects in movement and changes in the environment offer cues to direction and rate of change. Space perception occurs naturally and virtually. It occurs substantially through making-up by the past remembrances. And so though it is substantially predictive, surprises, deviations and deceptions do occur.

Space perception offers dimension, orientation and direction to the space. The dimensions are perceived in terms of body sizes and capacities. Orientation suggests the position of the causation in front, back, up, below, or sideways. “The horizontal, vertical, and sagittal planes divide space into various sectors: something is perceived as ‘above’ or ‘below’ (the horizontal plane), as ‘in front of’ or ‘behind’ (the vertical plane), or as ‘to the right’ or ‘to the left’ (of the sagittal plane). The Horizontal and Vertical have universal justification of the gravity, reinforced by the fluid levels. But it is the sagittal plane or the sense of left and right, which is self centred.

The depth in space is a perceived notion. Visually it is sensed by the stereophonic vision and fading over (only larger) the distance. Depth is perceived by scaling in scenic perspective. Visual depth perception is also a process of learning. Seafarers, aircraft pilots, mountaineers, desert travelers have extraordinary sense of space distances. Similarly architects, embroiders, watch repairers have coordinated visual and touch depth perception.

Aural perception of space dimension, orientation and direction operate differently. The two ears create stereophonic effect for richness of sound, but unlike vision do not lead to distinct direction or orientation of the space perception. The sense of the dimension, though is more accurate, as sound fades remarkably strongly even in the shorter depth. Aural perception has more deviations and deceptions. Depth or distance perception is due to the loudness and pitch, both affect little late (sound of lightening), but reinforce the information offered through the visual perception. Changes in pitch ( Doppler effect) of a moving object, defines the depth.

Touch perception of objects is governed by recognition of the edges or remarkable intermittent features. Touch perception is texture recognition combined with energy transmission (temperature, electrical, magnetic, vibrations etc.). These operate at touching or very close distance, but are highly variable. The perceiver and the perceived (object or an organism) both exchange the energies to form the perception. The touch perception plays very little role in perception of spatial dimensions in spite of transiting between edge to edge, or other features of the surface.

Clarity and Consistency of visual perception are very important features of experience. It is accepted that visual clarity depends on the distance, quality (angle, strength, contrast, colour) of illumination and physiological condition of the perceiver. Beyond these obvious parameters other factors are foreground-background, glare, framing of the view, other distractions. Consistency of visual sensation derives from field size, movement of the perceiver and within the scene, distractions, aberrations. Clarity and consistency, together depend on subjective aspects, such as the intent and duration of the perception.

Clarity and Consistency of aural perception occur in terms of the echoes, reverberation, presence-absence of background noise. It also depends on the dominant range of operative frequencies. Clarity is affected when one cannot decode a scrambled or garbled noise. This happens in large halls and open layout offices, where one subconsciously cannot decipher the message, and tries to interpret it. To reduce such irritations, ‘white-sounds’ -a background or masking noise are added to the space. Hospital rooms and commercial spaces with round the clock operations pose different aural profiles at different times of the day-night, ‘white sounds’ reduce such variations. Consistency of level and quality of sounds allows one to ‘fathom’ a space more effectively.

Clarity and Consistency in touch perception are important in space perception, so far these are demarcations of space zones. For persons with imperfect perceptive capacities (blind, deaf, old age, infants, sick) touch becomes an important faculty to reinforce the space extent. The consistency of touch is governed by duration and use of limbs that show better reception to touch.

 Peter Zumthor outlines (Atmospheres, p. 29) that, ‘Interiors are like large instruments, collecting sound, amplifying it, transmitting it elsewhere. That has to do with the shape peculiar to each room and with the surface of materials they contain, and the way those materials have been applied.’
