A modular pressure-sensitive motion detection system

Abstract

This invention provides a modular pressure-sensitive motion detection system, comprising a floor mat module, at least one sensing device, and a computing terminal. The floor mat module consists of a plurality of detachable and interlocking floor mat units, which users can arrange and combine into a first detection pattern (such as horizontal side-by-side) or a second detection pattern (such as vertical sequence) according to testing needs, providing visual guidance through the arrangement of the floor mats. The sensing device is disposed on the floor mat and uses a plurality of pressure sensors to detect changes in plantar pressure, and performs signal processing and bidirectional transmission through an internal processing unit and communication unit. The computing terminal receives the signals and generates a real-time pressure distribution map and pressure center trajectory through the motion analysis module (31), thereby calculating the user's arch type and balance stability index, and transmitting the results back to the display unit of the sensing device or displaying them on the computing terminal, achieving home-based, customized motion assessment and rehabilitation training effects.

The modular pressure-sensitive motion detection system as described in claim 1, wherein, The pressure sensors of the sensing device are distributed in the forefoot, arch, and heel areas of the user's foot. The sensing device is detachably embedded or attached to the top surface of the mat unit, so that the sensing device can move with the arrangement of the mat unit.

5. The modular pressure-sensitive motion detection system as described in claim 4, wherein, The motion analysis module calculates based on the pressure values ​​of the forefoot area, the arch area, and the heel area. When the pressure value of the arch area is lower than a first preset ratio, it is determined to be a high arch.
