Retention device for holding i.e. mobile phone in inner space of motor car, has control unit for receiving actuating signal and controlling function of actuator according to received actuating signal for effecting tactile feedback

摘要

The device (3) has a retainer part (31) for attaching a mobile apparatus (2). A magnet actuator (32) is arranged to produce a tactile feedback to the attached mobile apparatus. A control unit (33) receives an actuating signal and controls function of the actuator according to the received actuating signal for effecting the tactile feedback. The control unit varies strength of the tactile feedback dependent on shocks and/or vibrations in an inner space of a motor car. The control unit comprises a wired or wireless interface for receiving the actuating signal. Independent claims are also included for the following: (1) a mobile apparatus (2) a mobile apparatus and retention device arrangement (3) a method for operating a mobile apparatus (4) a method for operating a retention device (5) a method for providing tactile feedback to a user of a mobile apparatus.
