three-dimensional models of human movement

Eventually, computers might be able to model a virtual three-dimensional model of the human body right away by combing pictures from multiple video cameras like the way in which one's brain combines pictures from two eyes, but human perception is neither simple nor easy to duplicate. While human beings have adapted to deal with objects that leave the direct line of sight, are in the dark, or are complex, such conditions challenge optical tracking by current computing systems. With future formation, computing systems may be better able to make three-dimensional models from optical pictures, creating opportunities for more precise optical monitoring of body movement. Link to Graphical Interfaces to Support Information Search has further developments on VR.

Movement and contact as a method of interaction from computing systems to human beings is not well developed, but remains important. The human brain gets macro-scale information about the locations of body members from proprioceptors that monitor muscle movements. The brain also gets small-scale information concerning touch and texture from mechanoreceptors in the skin. Combined information from proprioceptors and mechanoreceptors tells you about tangible features of things in the setting. The page on Virtual Tours St. Louis, Missouri discusses additional info about these concepts.
