【摘要】：当用户与触摸屏交互时,有效和实时的力触觉交互技术对于增强现实感和沉浸感是非常重要的。设计了一种面向触摸屏图像信息感知的手指外骨架可穿戴式力触觉交互装置,利用平面四连杆机构作为外骨架传动机构,结合直流电机作为执行机构可为用户手部提供连续可控的力觉反馈,通过振动电机和压电陶瓷致动器提供两种类型的振动触觉反馈。该装置体积小、重量轻,功耗小,使用蓝牙通信,可扩展性强,方便使用及携带。为了表达图像中虚拟物体的空间力触觉信息,引入了实时的力触觉建模算法。当用户穿戴该装置在图像上滑动时,图像的一些特征信息将通过蓝牙与装置通信,包括每个像素点的形状高度和图像的边缘轮廓信息,能够使用户获得丰富的力触觉感受。最后,进行力触觉交互实验来评估该装置在表达触摸屏中图像的高度、轮廓和纹理等方面的性能。
[Abstract]:When the user interacts with the touch screen, effective and real-time force-tactile interaction technology is very important to enhance the sense of reality and immersion. In this paper, a wearable force-tactile interactive device of finger external skeleton is designed, which is oriented to the information perception of touch screen image. The planar four-bar linkage mechanism is used as the external frame transmission mechanism. Combined with DC motor as actuating mechanism, continuous controllable force feedback can be provided for the user's hand, and two types of vibration tactile feedback can be provided by vibrating motor and piezoelectric ceramic actuator. The device is small in size, light in weight, low in power consumption, and easy to use and carry with Bluetooth communication. In order to express the spatial force-tactile information of virtual objects in the image, a real-time force-tactile modeling algorithm is introduced. When the user wears the device to slide on the image, some characteristic information of the image will communicate with the device via Bluetooth, including the shape height of each pixel point and the edge contour information of the image. Finally, a force-tactile interaction experiment was carried out to evaluate the performance of the device in representing the height, contour and texture of the image in the touch screen.
