  • Patent number: 10095186
    Abstract: A wrist watch and method of activating a user interface of the wrist watch are described. The wrist watch comprises a display for providing a user interface for a user when wearing the wrist watch on a wrist, a first motion sensor arranged to detect motion of the wrist watch and a proximity detector arranged to detect the proximity of a hand of the user when wearing the wrist watch. A data processor is configured to activate the user interface when the first motion sensor detects that the wrist of the user has been raised and the proximity detector detects that the hand of the user has moved toward the wrist watch.
