Abstract

Systems and methods for gesture-based control are disclosed. In some embodiments, a system may include a wearable device configured to obtain physiological data and wrist location data. The system may be configured to detect a first gesture and transition to an object control state in which changes in the wrist location data and/or the physiological data are configured to control a movement of the object. In the object control state, the system may be configured to detect a first motion of a body part, generate a first command to move the object in a first command direction, detect a second motion of the body part, and generate a command to move the object in a second command direction. The system may detect a second gesture indicating an intention to cease control of the object, and transition out of the object control state.

Claims20

Dependent claims

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, 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 state of the person’s wrist;
wherein the system is configured to:
based on at least the physiological data, detect a first gesture indicating an intention to control an object;
in response to detecting the first gesture, transition to an object control state in which changes in the wrist location data and/or the physiological data are configured to control a movement of the object;
while the system is in the object control state:
detect, based on the physiological data and/or the wrist location data, a first motion of a body part of the person in a first motion direction;
in response to detecting the first motion of the body part of the person in the first motion direction, generate a first command to move the object in a first command direction that is mapped to the first motion direction;
detect, based on the physiological data and/or the wrist location data, a second motion of the body part of the person in a second motion direction that is different from the first motion direction;
and
in response to detecting the motion of the body part of the person in the second direction, generate a second command to move the object in a second command direction that is mapped to the second motion direction, the second command direction being different than the first command direction;
after generating the first and second commands to move the object in the first command direction and the second command direction, detect, based on at least the physiological data, a second gesture indicating an intention to cease control of the object;
and
in response to detecting the second gesture, transition out of the object control state.

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, the method comprising:

obtaining, using the wearable device, physiological data, the physiological data being configured to indicate a state of a person’s hand;
obtaining, using the wearable device, wrist location data, the wrist location data comprising information relating to a state of the person’s wrist;
based on at least the physiological data, detecting a first gesture indicating an intention to control an object;
in response to detecting the first gesture, transitioning the system to an object control state in which changes in the wrist location data and/or the physiological data are configured to control a movement of the object;
while the system is in the object control state:
detecting, based on the physiological data and/or the wrist location data, a first motion of a body part of the person in a first motion direction;
in response to detecting the first motion of the body part of the person in the first motion direction, generating a first command to move the object in a first command direction that is mapped to the first motion direction;
detecting, based on the physiological data and/or the wrist location data, a second motion of the body part of the person in a second motion direction that is different from the first motion direction;
and
in response to detecting the motion of the body part of the person in the second direction, generating a second command to move the object in a second command direction that is mapped to the second motion direction, the second command direction being different than the first command direction;
and
after generating the commands to move the object in the first command direction and the second command direction, detecting, based on at least the physiological data, a second gesture indicating an intention to cease control of the object;
and
in response to detecting the second gesture, transitioning the system out of the object control state.
