When selecting volume adjustment or channel selection, sliders appear. The user moves their hand, head, or object, in the required direction indicated by the slider to change the volume or to find the desired channel.
The technology can also be used with other screens. For example, YouTube tutorials, such as mending bikes or baking cakes, could be easily paused and rewound on tablet computers without users having to put down tools or mixing bowls.
Multiple pointers can be created to allow more than one user to point at drawings or pictures on interactive whiteboards simultaneously. Matchpoint also allows users to manipulate images on whiteboards by using two hands to zoom in and out, and rotate images.
In addition to short-term couplings, users can also link stationary objects to controls, which even when left for prolonged periods will retain their control function. For example, a mug sat on a table could change a track on a music player when moved left or right, and a rolling toy car could be used to adjust volume. Objects can lose their coupling with controls simply by removing them from the camera's field of view.
