Gesture Recognition

The most common current methods of communication from humans to computers, keyboard and mouse, are relatively unnatural and limiting. Even speech, although more natural, is limited without understanding of accompanying body gestures. As computers are further developed that can recognize human gestures, communication from humans to computers will become more natural and flexible. A Virtual Reality (VR) environment must engage vital sensory pathways with sufficient believability to provide participating human beings a sense of being in a real-world situation. With the constraints of applied science now available, this usually entails computer displays that cover a lot of the human range of sight with satisfactory clarity, high-end three-dimensional sound, and human to computer interaction based on head and hand location, motion, and configuration that records at least fifty times every second. More sophisticated touch-based communication that involves movement of the rest of the body and works with senses beside sight, hearing, and touch are generally above present day base-line standards for virtual reality. These advanced functions could, however, become the norm for Virtual Reality (VR) in the future. Details regarding VR at bidirectional interaction between humans and computers .

Current technologies for human to computer interfaces include: keypad/knobs; touch screen; mouse; joystick; trackball; steering wheel; digital pen; tablet; speech recognition; data hand device; gesture recognition; and complete-body virtual reality systems. These interfaces enable users to give direction to computers. Linked page gesture recognition in virtual reality also provides information about these issues.

Although the vast majority of virtual home tours are not yet enveloping or genuinely 3D Virtual Reality (VR), their growth is impressive and it is probable that genuinely multi-dimensional and three-dimensional real estate tours for both the commercial and residential property will be developed during the course of the next five years. See virtual reality and computer vision as well for interesting material regarding virtual reality.

The number of sensory pathways that should be actively involved and the extent of believability that are needed to be achieved so that a communication between a person and computer to be virtual reality morphs as technology progresses. This may be compared to the escalating norm for "high quality" sound encoding over the course of the last century -- building on progress in different modality recording.
