Abstract: With the rapid development of society, various new technologies are emerging, and virtual reality technology is born. Visual simulation technology is an important part of virtual reality technology and an important means of virtual reality. It can give people a variety of sensory feedback through the computer virtual reality environment, allowing people to experience freely without the constraints of time and space. It takes simulation as the ultimate goal, generates virtual images through the computer to form a realistic three-dimensional world, and simulates human senses such as vision and hearing. At present, visual simulation technology has been successfully applied in many fields, such as entertainment games, medical, military, simulation training and so on. Therefore, this paper focused on the human-computer interaction technology of virtual hands in visual simulation.

Keywords: visual simulation;virtual hand;human-computer interaction technology

虚拟手是虚拟现实技术的重要组成部分,也是虚拟现实技术在人机交互中的具体应用手段。对虚拟手进行深入研究,可以有效地促进虚拟现实技术的快速发展。本文研究了视景仿真中虚拟手的人机交互技术,以虚拟手作为切入点,基于C++与Vega的仿真视景环境,将虚拟手作为虚拟环境中人手的替代物,把现实中人手的操作信息与指令信息傳递到虚拟场景中,使得虚拟手可以做到与人相同的操作,进行实时的交互操作。这种方法可以使得用户具有较大的真实感和沉浸感。
