We report on an experiment on the distracting effects of in-car conversations through augmented-reality glasses. Previous research showed that in-car phone conversations can be distracting, but that the distraction might be reduced if the remote caller receives visual information about the driving context. However, what happens if such video sharing becomes bidirectional? The recent introduction of commercial augmented-reality glasses in particular might allow drivers to engage in video-supported conversations while driving. We investigate how distracting such video-based conversations are in an experiment. Our participants operated a simulated vehicle, while also playing a conversational game (Taboo) with a remote conversant. The driver either only heard the remote conversant (speech-only condition), or was also able to see the remote person in a virtual window that was presented through augmented reality (video call condition). Results show that our participants did not spend time looking at the video of the remote conversant. We hypothesize that this was due to the fact that in our experiment participants had to turn their head to get a full view of the virtual window. Our results imply that we need further studies on the effects of augmented reality on the visual attention of the driver, before the technology is used on the road.

使用增强现实驾驶时打电话：祝福还是诅咒？

我们报告了一项关于通过增强现实眼镜进行车内谈话分散注意力的实验。先前的研究表明，车内电话交谈可能会让人分心，但如果远程呼叫者收到有关驾驶环境的视觉信息，分心可能会减少。但是，如果这种视频共享变成双向的，会发生什么？特别是最近推出的商用增强现实眼镜可能允许驾驶员在驾驶时进行视频支持的对话。我们在实验中调查了这种基于视频的对话是如何分散注意力的。我们的参与者操作模拟车辆，同时还与远程熟悉者玩对话游戏（禁忌）。司机要么只听到对方的声音（只有语音条件），或者还能够在通过增强现实（视频通话条件）呈现的虚拟窗口中看到远程人员。结果表明，我们的参与者没有花时间看远程对话者的视频。我们假设这是因为在我们的实验中，参与者必须转过头才能看到虚拟窗口的完整视图。我们的结果意味着，在该技术在道路上使用之前，我们需要进一步研究增强现实对驾驶员视觉注意力的影响。我们假设这是因为在我们的实验中，参与者必须转过头才能看到虚拟窗口的完整视图。我们的结果意味着，在该技术在道路上使用之前，我们需要进一步研究增强现实对驾驶员视觉注意力的影响。我们假设这是因为在我们的实验中，参与者必须转过头才能看到虚拟窗口的完整视图。我们的结果意味着，在该技术在道路上使用之前，我们需要进一步研究增强现实对驾驶员视觉注意力的影响。
