3D interaction

In computing, 3D interaction is a form of human-machine interaction where users are able to move and perform interaction in 3D space. Both human and machine process information where the physical position of elements in the 3D space is relevant. In computing, 3D interaction is a form of human-machine interaction where users are able to move and perform interaction in 3D space. Both human and machine process information where the physical position of elements in the 3D space is relevant. The 3D space used for interaction can be the real physical space, a virtual space representation simulated in the computer, or a combination of both. When the real space is used for data input, humans perform actions or give commands to the machine using an input device that detects the 3D position of the human action. When it is used for data output, the simulated 3D virtual scene is projected onto the real environment through one output device or a combination of them. 3D’s early beginnings can be traced back to 1962 when Morton Heilig invented the Sensorama simulator. It provided 3D video feedback, as well motion, audio, and haptic feedbacks to produce a virtual environment. The next stage of development was Dr. Ivan Sutherland's completion of his pioneering work in 1968. He created a head-mounted display, the sword of Damocles, that produced a 3D, virtual environment by presenting a left and right still image of that environment.
