We, conduct tasks more efficiently, in certain positions or postures. To achieve, maintain or terminate (transit to another one) postures we normally do not need devices, but for some posturing certain devices and amenities are required. The capacity to change over to another posture and sustain it depends on the physiological structure of the body, deformities, age related in-capacities, motor (movement-flexibility) potential and response time etc. Body posture devices and amenities are primarily designed to make available maximum energy for the activity. The posture-devices could be support available from other beings. The efficiency of task performance is a direct function of the body posture achieved.
We need to take different types of body postures for conducting various tasks. The posture could be defined as main position of the body for the task, and micro variations that may be required for conducting sub-tasks. Other micro variations include postures for relief and diversion.
Devices related to postures include amenities that allow work in certain position and body configuration. Other devices extend the reach of human limbs, and thereby reduce the need for posturing. Posture devices are also used for correcting deformities and work deficiencies of the body. Understanding of Postures is very important in design of furniture, amenities, facilities, tools, gadgets and machines.
Gravity is one of the most important factors to affect the postures and the need for posture related devices. Besides the conduction of a task, the postures are formed in consideration of the Environment such as for the heat exchange of the body and moisture control mechanisms. Postures must allow functioning of the important Biological routines such as breathing, metabolisms, fluid control, blood circulation, etc. Postures are taken primarily to conduct tasks, and also allow Sensorial perception. Posturing instinctively takes care of needs for Security and survival.
