An input device is described which comprises a touch-sensitive surface and a force sensor, wherein the force sensor is adapted to detect a force applied to the touch-sensitive surface. The input device further comprises a vibration sensor and a control unit, wherein the control unit is coupled with the force sensor, the touch-sensitive surface and the vibration sensor. The control unit is adapted to validate a force detected by the force sensor as an input in dependence on a touch of the touch-sensitive surface and in dependence on a vibration detected by the vibration sensor. There is further described a motor vehicle which comprises such an input device. A method of detecting an input at an input device is further described.
