Perception is becoming aware of Objects and Environment. A person has natural or nominal capacities for sensorial perception. The sensorial faculties, though vary from person to person, and also depend on many other factors such as age, sex, moods, past experiences, sequences of happenings, motivation, learning capacity. The capacities are improved by various means of reach such as spectacles, hearing aids, insulators. The perception is also regulated by conversion processes, which diffuse, hasten, or delay through condensation, compression, enlargements, focussing, differentiation, etc. Perception of Objects in a space occurs as a sequence of events, where each segment is affected by the varying environment and the position of the perceiver.
The word Perception derives from Latin perceptiō (a receiving or collecting, taking cognizance of, intuitive or direct recognition of some innate quality, obtain, gather, seize entirely, take possession of, to grasp with the mind, learn, comprehend).
Perception occurs as congregation of several effects, and mutually compensative processes. We may not be able to isolate few parts of it. As for example, Smell and Taste often occur together. The sensory nodes have FIVE important characteristics that they have specific Location, Capacity and Multiplicity and the Duration.
● The Locations of the sensorial nodes provide information about the directionality, and encourages discrimination.
● The Capacity of the perceptive nodes is range bound which permit selections while providing comfort, sense of survival. Beyond the range bound capacity of the perception faculty, the perception process gets transmitted to other modes allowing different facilitation.
● The Multiplicity of nodes gives a sense of scale and referential positions.
● The Duration of perception gives a temporal scale. In other words The Location, Body capacities, Multiplicity and duration, all together and individually endow a Geo-Spatial identity.
● There are abnormal sensorial perceptions also. These arise from the Location related misinterpretations, Physiological deficiencies, differentiated perception of multiple nodes and time related intensifications and diffusions.
The process of cognition reveals how the environment is formatted, organized and represented in time and space. Environment helps in identification, and interpretation of the space, and so gives a measure to it. The measures are perceived because we have different types nodes of perception, where some have multiple and directional locations. The nodes also have a range bound capacity, beyond and under which the reception gets transferred to other systems, or ceases to be operative. With these operants’ one gets a sense of scale, size, gradations like concentration and diffusion, framing, juxtaposing, referencing, linkages, details and orientation.
Perception nominally means sensorial cognition, but could also be realization through other means. An understanding of a situation, acceptance or confirmation, are also part of the process of perception. There are some realizations that may not be attributed to sensorial nodes. Such non sensorial cognition makes us aware of orientations such as North, East, West, South, Up, Down, Front, Back, movements, acceleration-deceleration, energy flows, gravity, etc. There are other realizations that do not relate to physical perceptions, but are sometimes attributed to psychical experiences. These include empathy, sympathy, links or relationships between two objects and organisms, acknowledgement, familiarity, recollection of past events, fore-sightings, future purposes or utilities of objects and situations, orders in complex situations, hierarchies in multiple entities, etc. Cognition also involves forming expectations, directing the attention, learning and memory retention. At some level cognition is recognizing a thought, intuition, deduction, etc.
Objects are positioned in the Space, where the Environment manifests as a happening, marking the Time. In this sense a space and time form a matrix of relationship, and perception is becoming aware of such a matrix. Space perception is about recognizing the extent, gaining knowledge and schematising for means for sustaining the occupation. Perception is also regarded as ‘the modification of anticipation’ because some disequilibrium between expectation and stimulus. Designers create spaces that are anticipated, but with elements that are off the expectations. There are continuous process between perception and cognition (knowledge) that defines our expectations and fulfillment. It distinguishes, hypothesizes, bridges and replaces the voids.
