Abstract

Being able to hear objects in an environment, for example using echolocation, is a challenging task. The main goal of the current work is to use virtual environments (VEs) to train novice users to navigate using echolocation. Previous studies have shown that musicians are able to differentiate sound pulses from reflections. This paper presents design patterns for VE simulators for both training and testing procedures, while classifying users' navigation strategies in the VE. Moreover, the paper presents features that increase users' performance in VEs. We report the findings of two user studies: a pilot test that helped improve the sonic interaction design, and a primary study exposing participants to a spatial orientation task during four conditions which were early reflections (RF), late reverberation (RV), early reflections-reverberation (RR) and visual stimuli (V). The latter study allowed us to identify navigation strategies among the users. Some users (10/26) reported an ability to create spatial cognitive maps during the test with auditory echoes, which may explain why this group performed better than the remaining participants in the RR condition.

虚拟环境中回声导航的听觉反馈:训练程序和定向策略。
能够听到环境中的物体,例如使用回声定位,是一项具有挑战性的任务。当前工作的主要目标是使用虚拟环境(VEs)来训练新手用户使用回声定位进行导航。先前的研究表明,音乐家能够区分声音脉冲和反射。本文提出了训练和测试过程中虚拟现实模拟器的设计模式,并对虚拟现实中用户的导航策略进行了分类。此外,本文还提出了在虚拟机中提高用户性能的特性。我们报告了两项用户研究的结果:一项有助于改进声音交互设计的试点测试,以及一项让参与者在早期反射(RF)、晚期混响(RV)、早期反射-混响(RR)和视觉刺激(V)四种条件下进行空间定向任务的初步研究。后一项研究使我们能够确定用户之间的导航策略。一些用户(10/26)报告说,他们有能力在有听觉回声的测试中创建空间认知地图,这可能解释了为什么这一组在RR条件下比其他参与者表现得更好。
