Design of Wearable Fingertip Force Feedback System for Touch Screen Interaction
力触觉再现技术在增强用户与触摸屏交互的真实感和沉浸感方面发挥着越来越重要的作用,设计了一种面向触摸屏图像信息感知的可穿戴指端力反馈装置.设计基于线绳牵引驱动的指端力反馈机构,将装置分为驱动和可穿戴部分,使其具备小巧、轻便、易佩戴的特点.设计测控系统,实现了输出反馈力的检测和控制.研究图像信息提取和力触觉建模算法,获取图像中物体的三维特征信息,配合力反馈装置和测控系统实现图像纹理高度、外形轮廓信息再现反馈.实验结果表明,该装置最大可以提供5.3N的反馈力,能够帮助用户感知触摸屏中图像的高度和形状信息.
Force tactile representation technology plays an important role in enhancing the sense of realism and immersion between users and touch screens.A wearable fingertip force feedback device for touch screen image information perception is proposed.The fingertip force feedback mechanism based on string traction drive is de-signed,and the device is divided into driving and wearable parts,so that it has the characteristics of small,light and easy to wear.The measurement and control system is designed to detect and control the output feedback force.Image information extraction and force tactile modeling algorithms are studied to obtain three-dimensional feature information of objects in images,and combining force feedback device and measurement and control system to reproduce and feedback information of image texture height and contour.The experimental results show that the device can provide a maximum feedback force of 5.3 N,which can help users perceive the height and shape information of the image in the touch screen.
