Abstract: Technologies for detecting micro-motion based input gestures include a wrist-wearable computing device that includes sensors from which values for micro-motion states can be determined. Each micro-motion state is indicative of a motion-related characteristic of the wrist-wearable computing device that is used to determine whether a sequence of detected gesture steps matches an input gesture model associated with an input gesture. The input gesture model defines a required sequence of required gesture steps from which an input gesture may be determined.

Abstract: Technologies for determining a user's location include a mobile computing device to determine, based on sensed inertial characteristics of the device, a walking gait of a user. The walking gait is one of a first gait indicative of the user holding the g device to the user's side or a second gait indicative of the user swinging the device along the user's side. The device further detects that the user has taken a physical step based on the inertial characteristics and the determined walking gait of the user, and determines a raw directional heading of the device indicative of a direction of the physical step. The device determines an estimated location of the user based on the determined raw directional heading, an estimated step length, and the user's previous location.

Abstract: An activity monitoring circuit enables power conservation for an activity monitoring system. The activity monitoring system includes a sensor device that generates activity data based on detected movement. An activity monitoring circuit receives the activity data as input from the sensor device, and processes the activity data. Based on the processing, the activity monitoring circuit signals the sensor device to change a duty cycle of its operation, by adjusting how long it is on and off. The activity monitoring circuit can include a sensor hub that determines an activity state indicated by the activity data and generates a prediction of stability of the determined activity state based on historical activity data. Based on activity state and stability, the sensor hub can determine a duty cycle for operation of the sensor device.
