Abstract
Method and apparatus are provided for detecting hovering commands by a device with a display. In one embodiment, a method for detecting hovering commands by a device with a display comprises detecting a sequence of shadows from a hovering object by one or more light sensors of the device, where the sequence of shadows causes changes in light conditions on the display of the device, determining a leakage current corresponding to changes of light conditions by a controller of the device, determining an action performed by a user based on the changes of light conditions on the display by the controller of the device, determining a hovering command based on the action performed by the controller of the device, and executing the hovering command by the controller of the device.
