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

一些最早的虚拟现实(VR)愿景承诺沉浸在虚拟世界中，**参与者最终可能会忽略他们的身体形态，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有一些诱人的东西，承诺提供更深层次的身临其境体验。**在VR中使用我们的物理形式可以被视为躺在光谱上。一端是完全被动的VR体验**，比如在VR中看电影。在光谱的另一端，我们有**穿着全身套装的人**在全方位的平台上，用他们的整个身体来导航，探索**虚拟世界，并与**互动。今天的大部分研究都集中在光谱的另一端，参与者被**鼓励参与现实的身体体验。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，同样或更身临其境，**对更广泛的参与者(例如，行动不便的人)**可访问。**在这个研究项目中，我们将探索对物理和/或认知**努力要求较低的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**研究确定方向。我们将通过将对先前工作的审查与涉及迭代设计和原型设计的设计即研究**方法相结合来做到这一点。

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.
