Handheld and wearable devices are becoming ubiquitous in our lives and augmented reality technology is stepping out of the laboratory environment and becoming ready to be used by anyone with portable devices. The success of augmented reality applications for pedestrians depends on different factors including a reliable guidance system and preventing risks. We show that different guidance systems can be supplementary to provide directions to a point of interest and offer clues that help the user find the augmented data when they get close to the location they have to visit. We tested the helpfulness of a map with the points of interest, an image preview of the next point of interest to visit, and an arrow showing the direction to it. The results show that the effectiveness of these guidance systems depend on the distance to the point of interest and the accuracy of the data obtained from the Global Positioning System. We also measured the total time that participants spent looking at the screen, as well as the perceived elapsed time as a measurement of real world dissociation. Finally, we discuss preliminary results to minimize the risk of accidents when using augmented reality applications in an outdoor urban environment.
手持式和可穿戴设备在我们的生活中变得无处不在，增强现实技术也正在走出实验室环境，准备好让任何拥有便携式设备的人使用。增强现实应用程序在行人中的成功取决于不同的因素，包括可靠的导航系统和防止风险。我们表明，不同的导航系统可以互补，为兴趣点提供方向，并提供线索，帮助用户在接近要访问的位置时找到增强数据。我们测试了带有兴趣点的地图、下一个兴趣点的图像预览以及指向它的箭头的辅助性。结果表明，这些导航系统的有效性取决于与兴趣点的距离以及从全球定位系统获得的数据的准确性。我们还测量了参与者在屏幕上花费的总时间，以及作为现实世界分离度测量的感知流逝时间。最后，我们讨论了初步结果，以最大程度地降低在户外城市环境中使用增强现实应用程序时发生事故的风险。
