Exploring low physical effort and low cognitive demand interfaces for virtual reality

虚拟现实（VR）的一些最早的愿景承诺沉浸在虚拟世界中，参与者最终可以忽略他们的物理形式，而不是使用典型的物理输入来控制他们的体验。这个版本的VR有一些吸引人的地方，有望带来更深层次的沉浸式体验。在VR中使用我们的物理形式可以被视为躺在一个频谱上。一方面是完全被动的VR体验 **，比如在VR中看电影。在另一端，我们让人们在全方位的平台上穿着全身服，用他们的整个身体来导航，探索和与虚拟世界互动。今天的许多研究都集中在光谱的远端，其中鼓励参与者参与现实的物理体验。虽然这是一个令人兴奋的研究领域，但也有机会创造其他形式的虚拟体验，这些体验同样或更具沉浸感，并且可以让更广泛的参与者（例如，行动不便的人）访问。在这个研究项目中，我们将探索需要低物理和/或认知 ** 努力的VR交互模式（包括基于凝视的，被动触觉和脑机接口），为该领域的进一步研究建立方向。我们将通过回顾以前的工作与设计研究 ** 方法相结合，涉及迭代设计和原型设计。

Some of the earliest visions for virtual reality (VR) promised immersion in virtual worlds in ways that**participants could ultimately ignore their physical form, not using typical physical input to control their**experience. There is something alluring about this version of VR, promising a deeper immersive experience.**The use of our physical form in VR could be seen as lying on a spectrum. On one end there are VR experiences**that are completely passive, such as watching a movie in VR. At the other end of the spectrum, we have people**in full body suits on omni-directional platforms, using their entire body to navigate, explore and interact with a**virtual world. Much of today's research is focused on the far end of the spectrum, in which participants are**encouraged to engage in realistic physical experiences. While this is an exciting area of research, there are**opportunities to create other forms of virtual experience that are equally or more immersive, and that are**accessible to a wider range of participants (for example, people with limited mobility).**In this research project we will explore VR interaction modalities that require low physical and/or cognitive**effort (including gaze-based, passive haptic, and brain-computer interfaces), to establish directions for further**research in this space. We will do this by combining a review of prior work with a design-as-research**methodology involving iterative design and prototyping.
