Wearable touch sensor with area perception

Abstract

The invention firstly provides a wearable touch sensor with area perception, and the touch sensor comprises a coordinate system established according to an orthographic projection area area of wearable equipment, wherein the above coordinate system establishes virtual coordinates covering the surface of the wearable equipment. The touch sensor also comprises a plurality of power generation units arranged on the surface of the wearable equipment; each power generation unit is correspondingly provided with an address memory, and the address memory is used for storing coordinate values of each power generation unit in a coordinate system; when each power generation unit generates an electric signal, the electric signal is processed by the signal processing circuit to generate a clear digital signal, and the processor classifies the received coordinate information according to horizontal coordinates or vertical coordinates; the coordinate values of the same horizontal coordinates or vertical coordinates form a group, then the processor compares the vertical coordinates or horizontal coordinates in the same group and the minimum value and the maximum value obtained after comparison, the weighted average of the difference values of all the coordinates is calculated, the minimum weighted average is the adjacent nearest point, and the contact area can be formed by connecting the connecting lines between the nearest points.

Description

[0001] This patent application is a divisional application, the application number of the parent application is 2020109850702, and the application date of the parent application is September 18, 2020. technical field [0002] The invention relates to a tactile sensor, in particular to a wearable tactile sensor with area perception. Background technique [0003] Most tactile sensors use piezoelectric sensors to obtain sensing signals, but piezoelectric sensors are limited by their principles and cannot capture sensitive tactile actions. Moreover, with the advancement of the demand for virtual reality applications, the requirements for the information perceived by the tactile sensor are more stringent, among which the requirements for wearable and tactile contact area are one aspect. If the tactile sensor in the wearable device can sense the tactile area, it can provide more accurate information on the fitting condition of the device and the motion capture of the device. It i...
