Abstract

We present an experimental investigation of spatial audio feedback using smartphones to support direction localization in pointing tasks for people with visual impairments (PVIs). We do this using a mobile game based on a bow-and-arrow metaphor. Our game provides a combination of spatial and non-spatial (sound beacon) audio to help the user locate the direction of the target. Our experiments with sighted, sighted-blindfolded, and visually impaired users shows that (a) the efficacy of spatial audio is relatively higher for PVIs than for blindfolded sighted users during the initial reaction time for direction localization, (b) the general behavior between PVIs and blind-folded individuals is statistically similar, and (c) the lack of spatial audio significantly reduces the localization performance even in sighted blind-folded users. Based on our findings, we discuss the system and interaction design implications for making future mobile-based spatial interactions accessible to PVIs.

视觉障碍人士在智能手机上使用空间音频的指向任务

我们提出了一项实验研究，利用智能手机的空间音频反馈来支持视觉障碍(PVIs)的指向任务中的方向定位。我们使用基于弓箭比喻的手机游戏来做到这一点。我们的游戏提供了空间和非空间(声音信标)音频的组合，以帮助用户定位目标的方向。我们对正常、盲视和视障用户的实验表明:(a)在定位方向的初始反应时间内，空间音频对视障用户的效果相对高于蒙眼视障用户;(b)视障用户与蒙眼视障用户的总体行为具有统计学上的相似性;(c)即使蒙眼视障用户，空间音频的缺乏也会显著降低定位性能。基于我们的研究结果，我们讨论了系统和交互设计的含义，使未来基于移动的空间交互对PVIs无障碍。

期刊介绍： The ASME Journal of Computing and Information Science in Engineering (JCISE) publishes articles related to Algorithms, Computational Methods, Computing Infrastructure, Computer-Interpretable Representations, Human-Computer Interfaces, Information Science, and/or System Architectures that aim to improve some aspect of product and system lifecycle (e.g., design, manufacturing, operation, maintenance, disposal, recycling etc.). Applications considered in JCISE manuscripts should be relevant to the mechanical engineering discipline. Papers can be focused on fundamental research leading to new methods, or adaptation of existing methods for new applications.
