BODY POSITION OPTIMIZATION AND BIO-SIGNAL FEEDBACK FOR SMART WEARABLE DEVICES
摘要
Smart wearable devices and methods are disclosed for providing feedback for optimal placement of the wearable device. This includes systems and methods to lock or unlock a wearable device and/or notify external wearable/non-wearable devices depending on the states of the wearer by sending notification or providing feedback if mispositioned or repositioned on the wearer. A system and method are disclosed for providing a user indication of proper placement of a wearable device by providing feedback based on acquired bio-signal quality. In one embodiment, bio-signal quality is acquired by comparing a computed signal to noise ratio to that of an expected signal.
