<p>The device (5) has measuring sensors (6, 7) arranged at distance from each other on a body surface (8) of a user (1). The sensors produce respective output signals, which depend on positions of the respective sensors in a space. An evaluating device (9) derives an identification number from the output signals for description of a relative arrangement of the sensors with respect to each other. A signal transmitter (10) signals the user with a deviation of the identification number of a reference value or a target region as a false body attitude. The measuring sensors are designed as magnetic field sensors e.g. Hall sensors or gravity field sensors such as acceleration sensors.</p> |
