A large body of research in the field of virtual reality is focused on making user interfaces more natural and intuitive by leveraging natural body movements to explore a virtual environment. For example, head-tracked user interfaces allow users to naturally look around a virtual space by moving their head. However, such approaches may not be appropriate for users with temporary or permanent limitations of their head movement.
In this paper, we present techniques that allow these users to get virtual benefits from a reduced range of physical movements. Specifically, we describe two techniques that augment virtual rotations relative to physical movement thresholds.
We describe how each of the two techniques can be implemented with either a head tracker or an eye tracker, e.g. in cases when no physical head rotations are possible.
We discuss their differences and limitations and we provide guidelines for the practical use of such augmented user interfaces.
虚拟现实领域的大量研究致力于通过利用自然身体动作来探索虚拟环境，从而使用户界面更加自然和直观。例如，头部跟踪用户界面允许用户通过移动头部自然地环顾虚拟空间。然而，这种方法可能不适用于头部运动存在暂时或永久限制的用户。
在本文中，我们提出了一些技术，使这些用户能够从有限的身体动作范围内获得虚拟体验。具体来说，我们描述了两种相对于身体运动阈值增强虚拟旋转的技术。
我们描述了如何使用头部跟踪器或眼睛跟踪器来实现这两种技术中的每一种，例如在无法进行实际头部旋转的情况下。
我们讨论了它们的差异和局限性，并为这种增强型用户界面的实际使用提供了指导方针。
