3D human-computer interaction (3D HCI) refers to the methods and technologies that allow users to interact with computers in a three-dimensional space.
3D interaction is human-computer interaction in which the user's tasks are performed directly in a 3D spatial context.[1]
Full-duplex 3D HCI requires a 3D input device and a 3D display. The 3D display can be autostereoscopic, lightfield, or holographic.
It can be summed up as a situation where a person can move something around in 3D, and a computer knows where it is, and the computer can move something around in 3D, and the person knows where it is.
A main area of interest is 3D direct interaction.
It can involve solid view displays.
Control peripherals
- Motion Controllers: Devices like VR controllers that detect movement in three dimensions using IMUs and/or positional tracking, either optical or elsewise.
- Gesture Recognition: Cameras and sensors (e.g., Microsoft Kinect, Leap Motion) that capture body movements and hand gestures.
- Haptic Feedback: Systems that provide tactile feedback to the user, enhancing the sense of touch in a virtual environment.
Visual peripherals
- solid view displays, including biscopic displays and holographic displays
- VR headsets
Interaction techniques
- Manipulation of 3D Objects: Techniques for selecting, rotating, scaling, and otherwise interacting with virtual objects in a three-dimensional space.
History
3D computer interaction succeeds 2D interactions (using a mouse, keyboard, or touch screen).
