Abstract
A method for identifying head-shaking gestures and nodding gestures by using an accelerometer arrangement of a device that is worn on the head, the accelerometer arrangement providing acceleration signals for three linearly independent directions in space. The method includes the following steps: calculation of a norm of total acceleration with the aid of the acceleration signals provided by the accelerometer arrangement; and identification of head-shaking gestures and nodding gestures using the calculated norm of total acceleration; identification of a head-shaking gesture being performed as a function of a comparison between the calculated norm of total acceleration and a predetermined threshold value; and identification of a nodding gesture being performed as a function of identifying an oscillation of the calculated norm of total acceleration about a predetermined acceleration value.
