我们介绍了一项实证研究的结果，该结果调查了反馈，移动性和难度指数对用户面前水平平面中的式空间音频目标获取任务的影响。使用音频反馈，发现空间音频显示元素可以使用FITTS Law来描述可用的Dectic Interaction。与没有反馈的交互相比，反馈不会影响感知到的工作量或首选步行速度。发现移动性将相互作用速度和准确性降低20％。当参与者以预先屈服的步行速度的73％行走时，参与者可以执行神经空间的音频目标获取。提出的反馈设计是详细介绍的，并量化了可变目标宽度的效果。发现与空间音频显示的互动是对未来接口设计的可行解决方案。
We present the results of an empirical study investigating the effect of feedback, mobility and index of difficulty on a deictic spatial audio target acquisition task in the horizontal plane in front of a user. With audio feedback, spatial audio display elements are found to enable usable deictic interac-tion that can be described using Fitts law. Feedback does not affect perceived workload or preferred walking speed compared to interaction without feedback. Mobility is found to degrade interaction speed and accuracy by 20%. Participants were able to perform deictic spatial audio target acquisition when mobile while walking at 73% of their pre-ferred walking speed. The proposed feedback design is ex-amined in detail and the effects of variable target widths are quantified. Deictic interaction with a spatial audio display is found to be a feasible solution for future interface designs.
