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.

Abstract: The present invention relates to a system and a method for gathering ball game data and in particular tennis match data in real time. To this end the system comprises a hands-free voice receiving means (4) adapted to receive words spoken by the player (2) wearing the receiving means. The words are then analyzed by an analyzing means adapted to analyze a dedicated ball game vocabulary used by the player. The analysis of the spoken words translates these words into digital match data. This data can be displayed, at least as score of the game by a display (10). More elaborate match data information can be gathered. Such data may be fed to an expert system giving back advice to the player.

Abstract: An apparatus (10) for capturing tennis play data is preferably in the form of an apparatus which can be worn on the body of the player, particularly with an armband (12) on an arm of the player. By way of example, it comprises a voice recognition device with a microphone and particularly also motion sensors or further sensors. The sensors can record and later evaluate data from the player which are relevant to tennis play.
