Interaction with wrist-worn devices is currently constrained to either voice control or opposing hand control through physical touch on the device screen, crown, or buttons. With one handed control involving full hand extension and hand clenching in a fist, these movements are not discrete. Traditional smartwatch placement on one hand is controlled using the other hand. This is a discrete, yet inconvenient mode of control, especially in situations where the other hand is involved in another function. Some technologies enable one-handed control with hand clenching into a fist / extending into an open palm. However, this isn't discrete or necessarily ergonomic. This disclosure describes discrete, finger-based, single-hand gestures for controlling wrist-based devices. The described gestures are performed using the hand on which the device is worn, with no involvement from the other hand. The gestures include movements for core inputs, e.g., navigation, scrolling, confirmation, selection, etc., within a menu. The described finger gestures are ergonomic and work well for repetitive actions. The gestures advantageously use a single hand and rely on the user’s fine motor skills.
