ABSTRACT:
The manual operation of hearing devices is simplified using a remote control that provides a projection device in order to project virtual buttons on a back of a hand. A sensor device registers, as necessary, an operation of the virtual buttons, whereupon a corresponding control signal is wirelessly transmitted to the hearing device. Very large buttons can thereby specially be made available for older patients or those who are dexterilly challenged.
