人机交互技术的不断发展带来了对交互方式多元化、交互体验丰富化的需求。现有工作中，增强现实（AR）等交互技术依托的设备往往单纯作为信号接收工具，而并未链接到与用户间的交互步骤。本文将嵌入式硬件设备与AR技术进行结合，在一定程度上弥补了AR技术在嵌入式硬件设备领域应用的空白；同时评测了面对特殊场景与特殊交互内容时用户的实际体验感受，探讨了将本文模拟工作拓展成为实际场景中工作的可能性和可行性。

    首先，在Jetbot智能车硬件设备开发平台上，采用基于神经网络的计算机视觉方法，实现了Jetbot在实际场地上的巡线巡航；随后，基于Unity和Vuforia进行了以动物世界为主题的AR场景的设计、开发与构建，封装为Android移动应用程序，并依据一定的原则对实际场地进行了布置，以供Jetbot在正常巡航的前提下进行AR场景的呈现；为了获知本文工作的系统效果，设计了一项采用观察法和访谈法获取用户反馈的用户研究实验；最后，除了进行算法性能的仿真测试及系统运行效果的定性测试，还邀请了多名用户被试进行现场体验，并对其反馈进行了记录和分析。实验表明，本文工作所构建的基于Jetbot自主巡航的AR动物世界在指定场地上拥有较好的实际运行效果，体验者的反馈普遍积极，并得出本文工作在系统开发与集成、交互内容与形式等方面仍有较大提升空间和发展可能的结论。

  The continuous development of human-computer interaction technology brings the demand for the diversification of interaction modes and the enrichment of interaction experience. At present, the devices for augmented reality (AR) and other interactive technologies are often simply used as signal receiving tools, but not linked to the interactive steps with users. In this paper, the embedded hardware device is combined with AR technology, which in some way makes up the gap of AR in the field of embedded device. At the same time, the actual experience of users in the face of special scenes and interactive content is evaluated, and the possibility and feasibility of expanding the simulation work into real scenes are discussed.  

  Firstly, on the hardware development platform of Jetbot, the neural network-based computer vision method is adopted to realize Jetbot's line patrol on the actual site. Then, an AR Zoo scene was designed and developed based on Unity and Vuforia, which was packaged as an Android mobile application. The actual site was arranged according to certain principles, so that Jetbot could present the AR scene under the premise of autonomous cruise. In order to obtain the systematic effect of this work, a user research experiment using observation method and interview method was designed. Finally, in addition to the simulation test of algorithm performance and qualitative test of cruise effect, a number of subjects were invited for on-site experience, and their feedback was recorded and analyzed. The experiment shows that the AR Zoo scene based on Jetbot autonomous cruise has a good practical effect on the designated site, and the feedback of the experiencers is relatively positive. It is concluded that the work in this paper still has a great space for improvement in the aspects of system integration and interactive content.
