面向自然人机交互的力触觉再现方法综述

力触觉再现技术借助力触觉人机接口设备,提供了操作者与虚拟环境之间的力触觉交互,使得操作者能够主动地触摸、感知和操纵虚拟物体,从而有效增强了虚拟现实等系统的真实感和沉浸感,进一步拓展了虚拟现实等技术的应用领域。传统的穿戴式、力反馈操纵杆式力触觉再现设备在便携性、操作空间等方面存在局限性,随着计算机技术与消费电子的快速发展,面向自然交互的力触觉再现方法受到广泛的关注。评述了传统的穿戴式、力反馈操纵杆式力触觉再现设备后,重点阐述了非固定式和非接触式的两类面向自然交互的力触觉再现方法。在对比分析不同的力触觉再现方法之间的差异后,探讨了面向自然交互的力触觉再现方法的未来发展方向。

Haptic rendering methods for natural human computer interaction: A review

The haptic rendering technique provides the haptic interaction between the operator and virtual environment by means of a haptic human machine interface device, which enables the operator to touch, perceive and manipulate the virtual objects actively. The haptic rendering method enhances the realism and immersion of the virtual reality system, and further expands the application field of virtual reality technology. Traditional wearable haptic rendering devices and force feedback joystick haptic rendering devices have some limitations in portability, operating space and other aspects. As the rapid development of computer technology and consumer electronics, the haptic rendering methods for natural human computer interaction gain wide concern. Firstly, this paper introduces the traditional haptic rendering devices, such as wearable device and force feedback joystick device. Then, the haptic rendering methods for natural human computer interaction, including the ungrounded method and untethered method, are elaborated. After comparing and analyzing the differences of different haptic rendering methods, the future development direction of the haptic rendering methods for natural interaction is discussed.
