virtual reality and human vision

Vision is the single most vital human sense and three-dimensional depth perception is central to vision. Thus, 3D sensation is critical for enveloping Virtual Reality. Human eyes convert light into electro-chemical impulses that are transmitted and processed by means of several progressively more complex neural cells. Some cells register basic object and image components such as edges, color, and movement. Higher-order cells puts together these picture elements and make high-level interpretations about what is being seen. Key inputs that humans use for three-dimensional perception are built on this processing system and can be sorted into three general areas: interaction among objects; the shape of object outlines; and the appearance of object surfaces.

The exteriors of an object are in the spaces within its outline. Besides the interaction among things and the shape of object edges discussed, the texture and lighting of an object's surfaces also influence perception of three-dimensional sensation. Among the most important characteristics of three-dimensional perception of textures is how they connect with light. Human beings are used to viewing things lit from above by the sun and thus most readily interpret the three-dimensionality of components lit from above by a single light source. Nonetheless, light from several lights or from directions besides above can also convey three-dimensionality if done consistently. Virtual Tours San Jose, California also includes coverage of some of this VR material.
