AI Technical Summary

Technical Problem

Existing children's smartwatches fail to fully utilize the potential of PPG sensors and fail to effectively identify wearing status, resulting in health monitoring data that may be distorted or cannot be accurately obtained.

Method used

The PPG sensor obtains the human pulse signal every time a certain time interval to determine the wearing status. When the pulse signal is valid, make sure the device is worn correctly; when the signal is invalid, take photos with the camera, compare similarity, or use a three-axis accelerometer to detect the acceleration of motion to determine whether the device is disengaged from the wearer.

Benefits of technology

Accurate detection of wearable status is achieved, the intelligence and safety of the device is enhanced, the accuracy of health monitoring data is ensured, and unnecessary battery consumption or data loss is avoided.
