Shock touch protection of a mobile device

A mobile device comprising

• a data processing facility,
• a touch control facility arranged to provide a touch input signal to the data processing facility,
• a motion state sensor facility arranged to generate a shock indication signal indicative of a magnitude of a third or higher derivative of a position of the mobile device,
• a mode control facility for selecting one of a plurality of mutually different operational modes, at least comprising a normal operation mode wherein the touch input signal is used as control signal for controlling operation of the mobile device and a shock touch protection mode, wherein the touch input signal is inhibited;
• wherein the shock indication signal is also indicative of a direction of the third or higher derivative of the position of the mobile device and the mode control facility is arranged to select an operational mode in dependence on the magnitude and direction indicated by the shock indication signal.
