METHOD AND APPARATUS FOR PHYSICAL ACTIVITY TRACKING

摘要

In one aspect of the teachings herein, a physical activity tracking system includes a wearable electronic device that uses dual touch points for detecting control inputs by a user. Processing within the device complements the dual touch point interface by requiring simultaneous touch detections to register user inputs to the device, and by mapping dual-touch detections of different duration to different control actions. Use of the dual-touch arrangement and the associated processing provides a number of advantages, including intuitive operation and minimization of accidental activations by the user. Other advantages of the touch interface include the ability to seat or mount the device in a variety of carriers, such as bracelets, etc., that complement wearability of the device, while still allowing for convenient charging.
