A touch free input display control panel, may be used, to hygienically operate a device. Touch free input, allows the user, to activate the device's functions, which are displayed on the display, without physically touching the display. Limiting contact with the display, limits the possible transference of harmful bacteria and viruses, from the control panel to the users fingers. Limiting bacterial transmission between the user, and the panel, may be beneficial for users of multiuser public input displays, where contamination from bacteria on the displays is possible. Touch free displays may be used with the operation of devices, such as, elevators, as the elevator control panel. Touch free input may reduce static electric discharge, which may be beneficial in flammable environments, by reducing the possibility of flammable material combustion. Reducing static electric discharge may be beneficial in dry environments, such as, in a space station.
