An input device for controlling a device is provided. The input device comprises a sensor surface sensitive to being touched by a foreign body, and an evaluation unit, which is equipped to sense the positions of successively touched points of the sensor surface, and convert them into a control command for the device. The evaluation unit is connected to means for estimating an acceleration acting on the sensor surface and equipped, when converting into the control command, to weight a point touched at a time of intense acceleration change lower than a point touched at a time of slight acceleration change.
