Systems, methods and devices for recognizing user activity using data from accelerometer or other sensors. 'Feature-based' approach and 'model-based' approaches are described. In a feature-based approach, various values are extracted from input signals and projected onto a space that is selected to facilitate better segregation of data points. Classifiers identify the regions in this projected space in which the data points fall to distinguish between the different activity types. In a &#x201c;model-based&#x201d; approach, a generative model is trained for each activity type. Different activity types can be distinguished by identifying similarities between the input data with the generative models.

Systems, methods and devices for activity recognition

Systems, methods and devices that facilitate determination of enhanced exercise or physical activity metrics by considering multiple types of data. Metrics are computable by pre-processing, and in some cases segmenting, a variety of input signals, such as acceleration signals, electromyography signals or other signals from a wearable device.

Systems, methods and devices for exercise and activity metric computation

A system, method and device are described for detecting a heart rate. A sensing unit can have a skin-facing surface that is removably securable to a user's skin surface and include at least one sensor positioned to acquire a bio-signal from the skin surface. A controller can be configured to capture a bio-signal stream using the at least one sensor and generate a preprocessed bio-signal stream by band-pass filtering the captured bio-signal stream with a predetermined passband. The controller can also be configured to determine, in a moving window, heartbeat signal portions when the preprocessed bio-signal stream has heartbeat impulse characteristics and determine the time between adjacent heartbeat signal portions to compute the heart rate.
