Abstract

Claims (46)

1. A system for gesture-based control, the system comprising:

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, the physiological data being configured to indicate a state of a person's hand; and

wrist location data, the wrist location data comprising information relating to a position of the person's wrist;

wherein the system is configured to:

transition the system from a rest state to a first active state in response to detection of a first gesture, the first gesture being a wake gesture;

while in the first active state, detect, based on at least the physiological data, a second gesture;

in response to the second gesture, transition the system from the first active state to a second active state, the second active state being a graphical element selection state;

detect, based on at least the wrist location data, a motion of a wrist of the person while the system is in the second active state;

in response to the motion of the wrist of the person while the system is in the second active state, cause a selector to move across a series of graphical elements shown on the display;

while in the second active state, detect, based on at least the physiological data, a third gesture indicating an intention to select an indicated graphical element of the series of graphical elements that is indicated by the selector at the time the third gesture is detected;

in response to the third gesture and based on the motion of the wrist detected in the second active state, select the indicated graphical element.

2. The system of claim 1 , wherein the second gesture and/or the third gesture comprises a finger lift.

3. The system of claim 1 , wherein the second gesture and/or the third gesture comprises a pinch gesture.

4. The system of claim 1 , wherein while the system is in the second active state, a motion of the wrist of the user in a first direction relative to a body of the person causes the selector to move across the series of graphical elements shown on the display in the first direction.

5. The system of claim 1 , wherein the system is configured to perform an action in response to the third gesture and the selection of the indicated graphical element.

6. The system of claim 5 , wherein the action comprises launching an application.

7. The system of claim 1 , wherein the physiological data comprises biopotential data.

8. The system of claim 1 , wherein the system further comprises a responsive device, wherein the responsive device is configured to perform the one or more of the steps of detecting the first gesture, the second gesture, the motion of the wrist, and the third gesture based on the physiological data and/or the wrist location data obtained by the wearable device.

9. A system for gesture-based control, the system comprising:

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, the physiological data being configured to indicate a state of a person's hand; and

wrist location data, the wrist location data comprising information relating to a position of the person's wrist;

wherein the system is configured to:

transition the system from a rest state to a first active state in response to detection of a first gesture, the first gesture being a wake gesture;

while in the first active state, detect, based on at least the physiological data, a second gesture;

in response to the second gesture, transition the system from the first active state to a second active state, the second active state being a graphical element selection state;

detect, based on at least the wrist location data and/or the physiological data, an indicator motion gesture while the system is in the second active state;

in response to the indicator motion gesture while the system is in the second active state, cause a selector to move across a series of graphical elements shown on the display;

while in the second active state, detect, based on at least the physiological data, a third gesture indicating an intention to select an indicated graphical element of the series of graphical elements 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 indicator motion gesture detected in the second active state, select the indicated graphical element.

10. A method for gesture-based control, the method being performed using a system comprising 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 method comprising:

transitioning the system from a rest state to a first active state in response to detection of a first gesture, the first gesture being a wake gesture;

while in the first active state, detecting, based on at least the physiological data, a second gesture;

in response to the second gesture, transitioning the system from the first active state to a second active state, the second active state being a graphical element selection state;

detecting, based on at least the wrist location data, a motion of a wrist of the person while the system is in the second active state;

in response to the motion of the wrist of the person while the system is in the second active state, causing a selector to move across a series of graphical elements shown on the display;

while in the second active state, detecting, based on at least the physiological data, a third gesture indicating an intention to select an indicated graphical element of the series of graphical elements that is indicated by the selector at the time the third gesture is detected;

in response to the third gesture and based on the motion of the wrist detected in the second active state, selecting the indicated graphical element.

11. The method of claim 10 , wherein the second gesture and/or the third gesture comprises a finger lift.

12. The method of claim 10 , wherein the second gesture and/or the third gesture comprises a pinch gesture.

13. The method of claim 10 , wherein while the system is in the second active state, a motion of the wrist of the user in a first direction relative to a body of the person causes the selector to move across the series of graphical elements shown on the display in the first direction.

14. The method of claim 10 , further comprising performing an action in response to the third gesture and the selection of the indicated graphical element.

15. The method of claim 14 , wherein the action comprises launching an application.

16. The method of claim 10 , wherein the physiological data comprises biopotential data.

17. The method of claim 10 , wherein the system further comprises a responsive device, the responsive device being configured to perform the one or more of the steps of detecting the first gesture, the second gesture, the motion of the wrist, and the third gesture based on the physiological data and/or the wrist location data obtained by the wearable device.
