Its primary focus is head tracking with uses in virtual reality, simulation, video games, 3D modeling, computer aided design and general hands-free computing to improve computer accessibility. Tracking can be made sensitive enough that only small head movements are required so that the user's eyes never leave the screen.
Camera types are sensitive to ambient lighting and the mouse pointer may drift and inaccuracies result from head movements not intended to be mouse movements. Other examples of hands-free mice are units that are operated using switches that may be operated by the feet (or other parts of the body), such as the NoHands Mouse and the switch ...

For simple software, when the mouse starts to move, the software will count the number of "counts" or "mickeys" received from the mouse and will move the cursor across the screen by that number of pixels (or multiplied by a rate factor, typically less than 1). The cursor will move slowly on the screen, with good precision.
A trackball is a pointing device consisting of a ball housed in a socket containing sensors to detect rotation of the ball about two axis, similar to an upside-down mouse: as the user rolls the ball with a thumb, fingers, or palm the pointer on the screen will also move. Tracker balls are commonly used on CAD workstations for ease of use, where ...
The drone pilot in this video is a surveyor who uses the machinery to take aerial pictures of the properties and heritage landmarks that he works on. It’s a useful technique, and one that makes ...
A video camera with built-in microphones or line-in may not delay sound and video paths by the same amount. Solid-state video cameras (e.g. charge-coupled device (CCD) and CMOS image sensors) can delay the video signal by one or more frames. Audio and video signal processing circuitry exists with significant (and potentially non-constant ...
