Abstract
Hover detection technology, in which an image is captured from a camera while an illumination source is illuminating an area in front of a display surface and the image captured by the camera is analyzed to detect an object within an anticipated input region based on illumination of the illumination source. User input is determined based on the object detected within the anticipated input region and an application is controlled based on the determined user input.
