Abstract:The haptic rendering technique provides the haptic interaction between the operator and virtual environment by means of a haptic humanmachine 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 humancomputer 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 humancomputer 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.
