Abstract
A mobile communication device and associated control system is provided for determining a presence and location of pressure applied to the mobile communication device. The system can replace physical buttons on the mobile communication device. In embodiments, a sealed chamber, such as a tube, is filled with a pressure-transferring medium inside the sidewalls of the frame of the mobile communication device. Two (or more) pressure sensors can be mounted to the chamber to measure the pressure at two different locations in the chamber. In an embodiment, the time difference of the pressure wave arriving between the pressure sensors can indicate the location of the applied force. By knowing where the force is applied, a desired command from a user can be inferred.
