先前的研究表明，增强现实可以减少用户在完成程序性任务时的任务响应时间和脑力劳动。本文研究了通过提供基于投影仪的空间增强现实预测线索来提高用户性能和减少脑力劳动的技术。在这项研究中进行的两个实验的目的是隔离的性能和心理努力的差异，从几个不同的注释提示技术简单（实验1）和复杂（实验2）按钮按下任务。与现有的认知神经科学文献预测，注意力定向和干扰，我们假设，对于简单的程序性任务和复杂的搜索为基础的任务，有一个视觉线索引导到下一个任务的位置将积极影响性能相对于基线，无线索条件。此外，我们预测，基于方向的线索将提供一个更显着的积极影响比基于目标的线索。结果表明，在简单任务和复杂任务中，为下一个任务提供一条线是提高用户任务时间和脑力劳动的最有效技术。
Previous research has demonstrated that Augmented Reality can reduce a user's task response time and mental effort when completing a procedural task. This paper investigates techniques to improve user performance and reduce mental effort by providing projector-based Spatial Augmented Reality predictive cues for future responses. The objective of the two experiments conducted in this study was to isolate the performance and mental effort differences from several different annotation cueing techniques for simple (Experiment 1) and complex (Experiment 2) button-pressing tasks. Comporting with existing cognitive neuroscience literature on prediction, attentional orienting, and interference, we hypothesized that for both simple procedural tasks and complex search-based tasks, having a visual cue guiding to the next task's location would positively impact performance relative to a baseline, no-cue condition. Additionally, we predicted that direction-based cues would provide a more significant positive impact than target-based cues. The results indicated that providing a line to the next task was the most effective technique for improving the users' task time and mental effort in both the simple and complex tasks.
