复杂室内环境下增强现实导航系统对人寻路能力影响实验研究
首发时间:2020-10-14
摘要:增强现实(Augmented Reality,AR)技术是一种可以通过在现实世界中叠加计算机图形来增强人们的感知能力的技术。AR技术的一大应用领域就是导航和辅助寻路。目前大多数现有的AR技术在寻路导航领域的研究都侧重于系统开发的技术层面,很少有文献研究AR导航系统对人寻路表现的影响;并且几乎所有的研究都局限于基于智能手机的AR,只有极少数的研究包括沉浸式AR(头戴式AR)设备。与在寻路导航领域已经取得广泛研究的VR技术相比,AR环境中的人类寻路行为仍然是一个有待探索的领域。本文旨在研究AR技术在复杂建筑中如何发挥导航作用,以及它对人类寻路行为产生的影响。本研究开发了基于Microsoft HoloLens的头戴式AR设备的室内导航系统,并通过实验验证了它的导航效果。参与者在AR导航系统的帮助下探索建筑物后,再执行一系列寻路任务、绘图任务等,以评估其寻路表现以及认知地图的建立情况。该研究包括一项用户研究,以评价AR导航系统的有效性和用户满意度。

An Experimental Study on the Improvement of Augmented Navigation System on Human's Wayfinding Performance in Complex Indoor Environment
Abstract:Augmented Reality (also known as AR) is a novel technology that can enhance people’s perception by adding super-imposed computer graphics in the real world. With this characteristic, AR has the potential to enhance human performance in many ways, one of which is wayfinding. Most existing AR research in wayfinding fields has focused on the technological aspects of developing an AR-based software so to realize specific functions (e.g., navigation and evacuation), none of them has tried to understand the training effect of AR navigation or the impact it has on human wayfinding performance from the cognitive perspective. Needless to say, basically all the studies are limited to smartphone-based AR, only very few of them have included immersive AR (head-mounted AR). Compared to the extensive wayfinding research that has already been done in the real world and VR environment, human wayfinding behaviour in AR environment remains a field yet to be explored. This research aims to study how well the AR technology can facilitate navigation in complex building, and what impact it has on human wayfinding behaviour. For the purpose of this research, a head-mounted AR indoor navigation system based on Microsoft HoloLens was developed and employed in the experiment. Participants were asked to perform wayfinding tasks after they explored the building with the help of AR navigation system. Wayfinding data and sketch map were collected to evaluate their wayfinding performance and cognitive map. In order to release the potential of this technology, our AR indoor navigation system incorporated both functions of showing directional arrows and projecting holographic 3D floor plan onto the real world to help the user navigate through the complex indoor environments. A follow-up user study was also included to evaluate the effectiveness and user satisfaction of the AR navigation system.
