Abstract
Systems and methods for gesture-based control are provided. A system may include a wearable device configured to be worn on a wrist of a person and comprising one or more sensors and a display. The wearable device being configured to obtain at least physiological data being configured to indicate a state of a person's hand and wrist location data comprising information relating to a position of the person's wrist. The system may be configured to transition between states in response to gestures detected based on the physiological data and/or the wrist location data.
Core Innovation
The invention relates to a wrist-worn wearable device for gesture-based control. The wearable device is configured to obtain physiological data indicating a state of a person's hand and wrist location data relating to a position of the person's wrist. The system transitions from a rest state to a first active state in response to detection of a first gesture being a wake gesture.
While in the first active state, the system detects a second gesture based on at least the physiological data and transitions to a second active state that is a graphical element selection state. While in the second active state, the system detects motion of a wrist of the person based on at least the wrist location data and causes a selector to move across a series of graphical elements shown on the display.
While the system is in the second active state, a third gesture is detected based on at least the physiological data. The third gesture indicates an intention to select an indicated graphical element of the series that is indicated by the selector at the time the third gesture is detected, and in response to the third gesture and based on the motion of the wrist detected in the second active state, the system selects the indicated graphical element.
Claims Coverage
Independent claim coverage is provided for a system for gesture-based control and a method for gesture-based control. The core inventive features center on hand-state physiological data and wrist location data, a wake gesture to enter an active state, transition to a graphical element selection state, selector movement across on-display graphical elements based on wrist motion, and selection of the indicated graphical element with a third gesture indicating selection intention.
Wrist-worn gesture-based control with hand-state and wrist position inputs
A wrist-worn wearable device obtains physiological data indicating a state of a person's hand and wrist location data relating to a position of the person's wrist.
Wake gesture transitions to active states
The system transitions from a rest state to a first active state in response to detection of a first gesture being a wake gesture, and detects a second gesture while in the first active state to transition to a second active state that is a graphical element selection state.
Selector movement across graphical elements based on wrist motion
While in the second active state, the system detects motion of a wrist of the person based on at least the wrist location data and causes a selector to move across a series of graphical elements shown on the display.
Selection of indicated graphical element with a third gesture
While in the second active state, the system detects a third gesture based on at least the physiological data, the third gesture indicating an intention to select an indicated graphical element of the series indicated by the selector, and selects the indicated graphical element in response to the third gesture and based on the motion of the wrist detected in the second active state.
Indicator motion gesture moves selector
An indicator motion gesture is detected while the system is in the second active state using at least the wrist location data and/or the physiological data, and in response the selector is moved across the series of graphical elements shown on the display.
Method for gesture-based control
A method for gesture-based control includes the rest-to-selection workflow using the wake gesture, second gesture, wrist motion, third gesture, and selection of the indicated graphical element.
Across the independent claims, the core coverage requires physiological data indicating a hand state and wrist location data relating to wrist position, a wake gesture to enter an active state, a transition into a graphical element selection state via a second gesture, selector movement across on-display graphical elements based on detected wrist motion or an indicator motion gesture, and final selection of the indicated graphical element in response to a third gesture indicating selection intention.
