  "textContent": "The key (100) has a movement sensor (110) for detecting movement of the key, and a memory (120) for recording movement data (130) that are obtained from the detected movement. An interface (140) outputs the movement data to an external device (150), and an evaluation device (180) generates activation information as the movement data, where the activation information is classified from raw data (134) delivered by the sensor. The key is designed to detect different movement classes among a group of movement classes such as rest, walking, running, moving in stairs and/or cycling. The external device is designed as ignition key, personal computer, personal digital assistance or laptop. Independent claims are also included for the following: (1) a motor vehicle system comprising a controller (2) a motor vehicle navigation device comprising an interface (3) a method for operating an ignition key.",
