基于无线式数据手套的虚拟手控制系统研究

摘要

目的：建立基于无线式数据手套的康复训练平台，利用虚拟现实的视觉等反馈机制，弥补传统康复训练的不足，帮助患者在反复的尝试-练习-更正过程中，不断提高其参与积极性及康复效果。方法：使用多个弯曲传感器采集手指弯曲程度，通过分压电路转换成模拟信号，使用芯片(STC12C5A60S2)的模拟数字(AD)采集单元，转换为数字量并通过串口传输数据，通过蓝牙模块将数据无线发送至主机端，数据提取后用于控制虚拟手。结果：弯曲传感器数据采集准确、有效，利用无线蓝牙进行数据传输，其传输稳定方便，三维虚拟手模型控制连续及有效。结论：构建一套基于无线式数据手套的虚拟手控制系统，能够有效用于患者的手部运动康复。%Objective:To establish a rehabilitation training system based on virtual hand model, in order to make up the lack of traditional rehabilitation by using vision feedback mechanism of virtual reality, and help patients raise participation enthusiasm and rehabilitation effect through the process of attempt-exercise-correction.Methods: Flex-sensor was used to collect the angle of fingers’ bending. The AD collection module was used to transform the signal to digital and transmitted by serial port.Then the data was transmitted to computer by bluetooth module and used to control the virtual hand.Results: Hall current sensor was accurate and effective for data collection. The acquisition terminal and monitor server were fast and convenient for data transmission and management.Conclusion: A control system for virtual hand based on wireless data glove was constructed, and it could be used effectively for the recovery of hand movement.
