virtual reality and computer vision

One way of information transmission from humans to computers is "computer vision" in which advanced analysis of camera images of human movement by a computer allows the computer system to distinguish vital patterns and gestures of body movement. In any event, this technology has limitations. The relevant portions of one's body must all be visible by the camera. They should not be obscured by elements of the setting or by other portions of the body. Some gestures are self-occluding by nature. This method is also constrained by available light. Further, Virtual Worldlets Network is of interest.

The formation of microscale lens and arrays of microscale mirrors with invisible polymers is opening up a whole new generation of three-dimensional imaging. Arrays of microscale lenses made from polymeric or elastomeric materials can be directed to converge by shrinking or expanding using piezoelectric currents. The interaction of holographic laser images with micro-lens or micro-mirror arrays can lead to genuinely three-dimensional moving images. Linked page Virtual Tours Minnesota also has information about this.
