Directional cues are crucial for environmental interaction. Conventional methods rely on symbolic visual or auditory reminders that require semantic interpretation, a process that proves challenging in demanding dual-tasking scenarios. We introduce a novel alternative for conveying directional cues on wearable displays: directly triggering motion perception using monocularly presented peripheral stimuli. This approach is designed for low visual interference, with the goal of reducing the need for gaze-switching and the complex cognitive processing associated with symbols. User studies demonstrate our method's potential to robustly convey directional cues. Compared to a conventional arrow-based technique in a demanding dual-task scenario, our motion-based approach resulted in significantly more accurate interpretation of these directional cues ($p=.008$) and showed a trend towards reduced errors on the concurrent primary task ($p=.066$).

翻译：定向线索对于环境交互至关重要。传统方法依赖于需要语义解释的符号化视觉或听觉提示，这一过程在要求苛刻的双任务场景中被证明具有挑战性。我们提出了一种在可穿戴显示器上传递定向线索的新颖替代方案：利用单眼呈现的周边刺激直接触发运动感知。该方法旨在实现低视觉干扰，其目标是减少视线切换的需求以及与符号相关的复杂认知处理。用户研究表明，我们的方法具有稳健传递定向线索的潜力。在一个要求苛刻的双任务场景中，与传统的基于箭头的技术相比，我们基于运动的方法导致对这些定向线索的解读显著更准确（$p=.008$），并且在并发的首要任务上显示出错误减少的趋势（$p=.066$）。
