Knocking event detection method and device, medium and head-mounted equipment

Abstract

The invention discloses a knocking event detection method and device applied to head-mounted equipment, a medium and the head-mounted equipment. The head-mounted equipment comprises a GMR magnetic sensor and a force sensor. According to the method, signals collected by the GMR magnetic sensor and a force sensor are used for calculating the corresponding knocking speed and knocking force respectively, then whether the knocking speed and the knocking force meet preset requirements at the same time or not is judged, and when the knocking speed and the knocking force meet the preset requirements,it is determined that a knocking event is generated to enter control logic corresponding to the knocking event. The GMR magnetic sensor has the characteristic of high accuracy; the GMR magnetic sensorand the force sensor have small interference influence on vibration, so that the sensitivity to a knocking event can be improved. The influence of mistaken touch can be effectively avoided through the mode of combining the GMR magnetic sensor and the force sensor, and the judgment accuracy is improved.

Description

technical field [0001] The present application relates to the field of wearable devices, in particular to a detection method, device, medium and head-mounted device for a knock event. Background technique [0002] Head-mounted devices in this application mainly refer to smart head-mounted devices, including true wireless stereo (TWS) earphones, AR glasses, etc. Taking the TWS headset as an example, it judges the user's tap event through the acceleration sensor or touch sensor, sends the detected tap event to the micro control unit (MCU) for information analysis, and performs corresponding actions, such as pausing playback, Call answering and hanging up, etc. [0003] However, during the wearing process of the user, there may be movements such as jumping, which will cause the TWS earphones to vibrate and generate acceleration signals, which will cause the problem of false detection of tap events.

AI Technical Summary

Problems solved by technology

[0003] However, during the wearing process of the user, there may be movements such as jumping, which will cause the TWS earphones to vibrate and generate acceleration signals, which will cause the problem of false detection of tapping events.

For the touch sensor to detect the knock event, when the hair flutters, it is easy to generate a touch signal, and it is easy to cause the problem of false detection of the knock event.

When the problem of false detection of a tap event occurs, it will cause the trigger action corresponding to the tap event, such as suddenly playing music, pausing, hanging up the phone, etc., which will bring a poor experience to the user
