Abstract
The present application provides methods and devices for determining an action and/or an action part, and generally relates to the field of wearable devices. A method disclosed herein comprises: in response to that a first part on a body of a user executes an action, acquiring target blood flow information of the first part or a second part corresponding to the first part; and determining the first part and/or the action according to the target blood flow information and reference information. The methods and devices disclosed provide a new scheme for recognizing an action and/or an action part.
Claims19
A method for determining an action or an action part, wherein the method comprises:
- detecting photoplethysmography (PPG) information;
- when the PPG information indicates that a user has executed an action using a first body part, acquiring target photoplethysmography (PPG) information of the first body part or a second part corresponding to the first body part;
- and
- determining the first body part or the action according to the target PPG information and reference information by determining target difference information according to the target PPG information and the reference information, wherein determining the target difference information comprises:
- dividing the target PPG information into a plurality of sub target PPG information according to cycles;
- performing cross-correlation computation on the plurality of sub target PPG information respectively with the reference information;
- and
- determining the target difference information according to the cross-correlation computation result.
