虚拟现实 (VR) 是一种日益增长的娱乐来源，但视障人士尚未有效融入其中。音频提示是对视觉效果的补充，使体验更加身临其境，但不是主要提示。为了解决这个问题，我们实现了一款名为 Virtual Showdown 的 VR 游戏。我们将虚拟对决基于一款名为“对决”的现实世界游戏，人们可以利用听觉来定位对手并击球。此外，我们开发了言语和言语/振动支架来教人们如何玩虚拟对决。我们评估了 Virtual Showdown 的可接受性，并在一项针对 34 名视障青少年的实证研究中比较了我们的支架。 33 名参与者希望再次玩虚拟对决，我们了解到，使用口头支架或之前有过对决经验的参与者得分更高。我们的实证研究结果为未来无障碍 VR 体验的设计提供了信息。
Virtual Reality (VR) is a growing source of entertainment, but people who are visually impaired have not been effectively included. Audio cues are motivated as a complement to visuals, making experiences more immersive, but are not a primary cue. To address this, we implemented a VR game called Virtual Showdown. We based Virtual Showdown on an accessible real-world game called Showdown, where people use their hearing to locate and hit a ball against an opponent. Further, we developed Verbal and Verbal/Vibration Scaffolds to teach people how to play Virtual Showdown. We assessed the acceptability of Virtual Showdown and compared our scaffolds in an empirical study with 34 youth who are visually impaired. Thirty-three participants wanted to play Virtual Showdown again, and we learned that participants scored higher with the Verbal Scaffold or if they had prior Showdown experience. Our empirical findings inform the design of future accessible VR experiences.
