Abstract: A device for sports applications is provided having a housing adapted to be worn on and fixed to the body of a person, and in particular a housing adapted to be worn on and to be fixed to an arm of a person. The device includes a processor and inertial sensors. Inertial sensors are arranged within the housing and connected to the processor and a predetermined characteristic movement of the body of the person is detectable. The detection of the movement provides a user input and/or starts a time frame for entering a command or information into the device during the time frame and the processor updates its state depending on the command or information received during the time frame. By this device it is possible to enter commands or information almost without distraction to the user so that commands or information can be entered during a sports activity, for example during a tennis match.
