VR交互体验中沉浸感与舒适度的平衡设计

目的 虚拟现实技术让体验者获得亲临环境的感受,而高沉浸感带来的眩晕往往让用户体验的舒适度大为降低,沉浸感与舒适度是评价虚拟现实内容质量的两个重要指标.在实际开发过程中,VR交互体验中沉浸感和舒适度的矛盾也是一直以来限制虚拟现实技术广泛应用的一个主要因素.本文从沉浸感和舒适度的概念及相关影响因素入手,提出自然交互、稳定视觉和多通道刺激补偿综合设计的原则.方法 应用上述3种原则,进行虚拟场景作品设计,并与传统方法作品进行对比实验,采用5点沉浸感量表和SSQ量表分别评价两组作品的沉浸感和舒适感.结论 综合设计原则对平衡沉浸感和舒适度有一定效用,可以增强虚拟现实内容的沉浸感并有效降低虚拟现实运动症的发生率,是一种没有副作用且可有效平衡沉浸感和舒适度的技术方案.

Balance Design of Immersion and Comfort in Virtual Reality Technology

Virtual Reality (VR) technology allows users to experience the reality-like scene, while the vertigo caused by high immersion often reduces the comfort of users'' experience. Immersion and comfort are two important indicators to evaluate the content quality of Virtual Reality. In the actual development process, the contradiction between immersion and comfort in VR technology has always been a major factor limiting the wide appliance of VR technology.Based on the concept of immersion and comfort and related factors, this paper puts forward the comprehensive design principles of natural interaction, stable vision, and multichannel stimulus compensation. Based on the above three principles, the virtual scene works were designed and compared with the traditional works. The immersion and the comfort of the two groups of works were evaluated by the 5 Point-Scale and SSQ Scale. The results show that the comprehensive design principles have a certain effect on balancing immersion and comfort, which can enhance the immersion of Virtual Reality content and effectively reduce the incidence of virtual reality motion sickness. It is a technical scheme without side effects and can effectively balance immersion and comfort.
