Abstract
Methods and systems are provided for a multi-level command sensing apparatus that includes a matrix of light sensors and light sources and that may also serve as the display. In one embodiment, a method for performing multi-level command sensing by a multi-level command sensing apparatus comprises detecting a leakage current corresponding to changes of light conditions on a display by one or more light sensors of the multi-level command sensing apparatus, determining an action performed by a user based on the changes of light conditions on the display by a controller of the multi-level command sensing apparatus, determining a command based on the action performed by the controller of the multi-level command sensing apparatus, and executing the command by the controller of the multi-level command sensing apparatus.
