Shock touch protection of a mobile device
First Claim
1. A mobile device comprising:
- a touch signal controller configured to provide a touch input signal;
a motion state sensor configured to generate a shock indication signal that indicates a magnitude and a direction of a third or higher derivative of a position of the mobile device;
a threshold comparator; and
a mode controller configured to select, based on the shock indication signal, one of a plurality of mutually different operational modes comprising;
a normal operation mode where an operation of the mobile device is responsive to the touch input signal, anda shock protection mode where the operation of the mobile device in response to the touch input signal is inhibited dependent upon the shock indication signal,wherein the threshold comparator is configured to;
perform a comparison the magnitude indicated by the shock indication signal with a shock threshold value, andprovide a mode control signal that indicates a result of the comparison, andwherein, upon indication by the mode control signal that the magnitude is greater than the shock threshold value, the mobile device operates in a shock touch alert mode that prompts a user to activate the shock touch protection mode.

Abstract
A mobile device (1) is disclosed comprising a data processing facility (10), a touch control facility (20) arranged to provide a touch input signal (St) to the data processing facility, and a motion state sensor facility (30) arranged to provide a shock indication signal (Sj) indicative for a magnitude of a third or higher derivative of a position of the mobile device. The mobile device further comprises a mode control facility (15) for selecting one of a plurality of mutually different operational modes (M1, M2). The plurality of mutually different operational modes at least comprises a normal operation mode (M1) wherein the touch input signal is used as control signal for controlling operation of the mobile device and a shock touch protection mode (M2), wherein the touch input signal is inhibited.
