A touchless method for registering commands from a display (e.g. reconfigurable display) may include any of various components. The method may use a light sensor in front of or behind the display to detect light reflected by a user's finger approaching a control option displayed on the display. Light used to display images may be provided at a frequency and/or time that can be identified by a processor connected to the light sensor, or can possess some other unique property (e.g. color) which may be distinguished by the processor.
