Abstract

The embodiment of the present invention provides a wearable device and a fall detection method applied to the wearable device, which senses the real-time acceleration of three axes of the wearable device through an acceleration sensor, and selects one of the axes according to the real-time acceleration values ​​of the three axes as the discriminant axis. In addition, the extreme point waveform that meets the fall condition is calculated on the selected discriminant axis, and then the fall event is analyzed by calculating the variance of multiple data before, during, and after the extreme point waveform and the variance of the data points in a stable area after the waveform. Detection is performed, so that the detection of the fall event is more accurate and can effectively avoid misidentification.

Description

technical field [0001] The present invention relates to the field of wearable devices, in particular to a wearable device and a fall detection method applied to the wearable device. Background technique [0002] At present, wearable devices such as smart glasses, smart gloves, smart bracelets, smart watches, and smart clothing have been widely recognized by the public and widely used. The application of wearable devices to the elderly to monitor and warn of dangerous events such as falls or falls is a typical application of wearable devices. Existing fall detection methods applied to wearable devices include fall detection methods based on graphic images, fall detection methods based on acoustics, and fall detection methods based on wearable sensors. However, most of the current fall detection methods have the defects of low detection accuracy, high false recognition rate and high false negative rate. Therefore, how to accurately detect and report a fall or fall event is a...
