音频导航工具有可能帮助视障人士（VIP）独立导航，但今天的音频导航工具只是引导用户到目的地，而不是给用户充分的自由，探索和导航环境本身。为了解决这个问题，我们提出了NavStick，一个自我导向的音频导航工具的虚拟环境。NavStick重新设计了游戏控制器的拇指操纵杆，允许用户通过以圆形方式“擦拭”拇指操纵杆来调查他们的周围环境。我们还描述了一个用户研究，我们正在执行比较NavStick与今天的指南为基础的音频导航工具。
Audio navigation tools have the potential to help visually impaired people (VIPs) navigate independently, but today's audio navigation tools merely guide users to destinations rather than give users the full freedom to explore and navigate environments themselves. To address this problem, we present NavStick, a self-directed audio navigation tool for virtual environments. NavStick repurposes a game controller's thumbstick to allow a user to survey their immediate surroundings by "scrubbing" the thumbstick in a circular fashion. We also describe a user study that we are performing to compare NavStick with today's guide-based audio navigation tools.
