3D human-computer interaction

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 HCI leverages depth, volume, and spatial context to enhance user experiences, unlike traditional 2D interactions (using a mouse, keyboard, or touch screen).

The main area of interest is 3D direct interaction.

It can involve solid view displays.

Input devices

• Motion Controllers: Devices like the Nintendo Wii Remote or VR controllers that detect movement in three dimensions.
• 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.

Output devices

• solid view displays, including biscopic displays and holographic displays
• VR headsets
• Augmented Reality (AR): Overlaying digital information on the real world, typically through devices like AR glasses or smartphones.

Interaction techniques

• Manipulation of 3D Objects: Techniques for selecting, rotating, scaling, and otherwise interacting with virtual objects in a three-dimensional space.
