Abstract: The various implementations described herein include methods and systems for power-efficient processing of neuromuscular signals. In one aspect, a method includes: (i) obtaining a first set of neuromuscular signals; (ii) after determining, using a low-power detector, that the first set of neuromuscular signals require further processing to confirm that a predetermined in-air hand gesture has been performed: (a) processing the first set of neuromuscular signals using a high-power detector; and (b) in accordance with a determination that the processing indicates that the predetermined in-air hand gesture did occur, registering an occurrence of the predetermined in-air hand gesture; (iii) receiving a second set of neuromuscular signals; and (iv) after determining, using the low-power detector and not using the high-power detector, that a different predetermined in-air hand gesture was performed, performing an action in response to the different predetermined in-air hand gesture.

Abstract: Methods and wearable devices for optimizing power consumption using sensor-based position and use determinations are described here. One example method is performed at a device that includes a first sensor configured to operate with a first power consumption rate and a second sensor configured to operate with a second power consumption rate. The method includes, while a component associated with the second sensor is in an inactive state, receiving first sensor data, and determining whether the first sensor data indicates movement of the device. The method also includes, when movement of the device is indicated, operating the second sensor in an active state. The method further includes, after activating the second sensor, when second sensor data from the second sensor indicates that the device has been placed on a user’s body, continuing to operate the second sensor in the active state.
