Q:Describe the most fantastic input and output devices in the near future .

A: I think the VR(Virtual Reality) devices would be popular.

VR is a technology that uses computer technology as its core to generate a realistic virtual environment that integrates visual, audio, and tactile sensations. Users use the necessary equipment to interact with objects in the virtual world in a natural way and influence each other. It has multi-sensory, in addition to the visual perception of a typical computer, there are auditory perception, tactile perception, motion perception, and even taste, smell, perception, and so on.

Virtual reality is a combination of multiple technologies, including wide-view three-dimensional display technology, tactile/force feedback, and voice input and output technologies. In VR systems, the input and output of speech are very important. And for the interaction between the user and the computer, because there are six degrees of freedom in the three-dimensional space, it is difficult to find an intuitive way to map the mouse's plane motion into any three-dimensional space. Currently, there are already some devices that can provide six degrees of freedom, such as 3Space digitizers and Space Ball. Other devices with superior performance are data gloves and data clothing.
