Search tasks in production environments have been shown to be significantly improved by attention guiding techniques in augmented reality (AR). In mobile use cases, head-mounted displays support context-sensitive and flexible search tasks. To improve search time and navigation efficiency, first concepts like attention funnel and spherical wave based guidance techniques have been tested successfully in comparison to simple arrow navigation. Existing research indicates that for two-dimensional interfaces, a differentiation into coarse and fine navigation will result in further performance improvements. In this article, a laboratory study is presented with a stereoscopic head-mounted display that examines whether an additional arrow guiding technique for coarse navigation could improve both search time and efficiency of existing techniques. Results show objectively superior performance for one of the combined techniques in comparison to the unimodal attention guiding techniques and subjective preference by the participants. Further research should investigate the performance in a real environment.

二胜于一。通过组合技术改进 AR 中的注意力引导

生产环境中的搜索任务已被证明通过增强现实 (AR) 中的注意力引导技术得到了显着改善。在移动用例中，头戴式显示器支持上下文敏感且灵活的搜索任务。为了提高搜索时间和导航效率，与简单的箭头导航相比，注意力漏斗和基于球面波的引导技术等第​​一个概念已经过成功测试。现有研究表明，对于二维界面，粗略导航和精细导航的区分将导致进一步的性能提升。在本文中，一项实验室研究展示了立体头戴式显示器，该研究检查了用于粗略导航的附加箭头引导技术是否可以提高现有技术的搜索时间和效率。结果表明，与参与者的单峰注意力引导技术和主观偏好相比，其中一种组合技术的客观表现更出色。进一步的研究应该调查真实环境中的性能。
