Embodiments of the relate generally to electrical and electronic hardware , computer software, wired and wireless network communications, and wearable computing devices for facilitating health and wellness -related information. More specifically , disclosed are systems ,methods, devices , computer readable medium ,and apparatuses configured to determine activity and activity types , including gestures , from sensed motion signals using , for example, a wearable device (or carried device) and one or more motion sensors. In one embodiment, an apparatus can include a wearable housing and a motion sensor. The apparatus can also include a signal preprocessor , which may include a sample rate controller configured to modify a sample rate of a motion sensor signal to form an adjusted sample rate with which to sample the motion sensor signal. Further , the apparatus can include an intermediate motion signal generator and an activity processor configured to identify an activity based on the intermediate motion signals.
