用AR让博物馆里的机器人模型动起来，帮游客直观理解导航原理。
RHINO-AR: An Augmented Reality Exhibit for Teaching Mobile Robotics Concepts in Museums
- 将虚拟机器人叠加到真实展厅，通过AR实时呈现传感与路径规划过程。
- 22人测试显示，用户对导航概念理解提升，且更偏爱AR版而非VR版。
- 适合科普展览、教育机构，帮助非专业人士看懂移动机器人技术。
我们提出RHINO-AR，一个交互式增强现实（AR）博物馆展项，将历史移动机器人RHINO重新置于德国波恩博物馆的原始展览环境中。该系统基于此前的RHINO-VR工作，后者在虚拟现实中重建了机器人及其环境。尽管体验生动，但存在参观者与真实空间及实体机器人分离的问题。RHINO-AR通过将虚拟机器人直接放置于真实博物馆空间中，弥合了这一现实差距。系统部署于Magic Leap 2头显，采用Unity实现，结合实时环境网格化与LiDAR感知、可通行性分析、路径规划等交互可视化，使非专业观众也能理解原本不可见的机器人运行机制。我们在两日博物馆研究中对22名参与者进行了评估，考察可用性、技术性能、满意度、概念理解及与RHINO-VR的偏好对比。结果显示，RHINO-AR广受好评，有效传达关键导航概念，并因更强的物理锚定和更高真实性而普遍优于VR版本。
原文摘要 · Abstract (English)
We present RHINO-AR, an interactive Augmented Reality (AR) museum exhibit that reintroduces the historical mobile robot RHINO into its original exhibition environment at the Deutsches Museum Bonn. The system builds on our previous work RHINO-VR, which reconstructed the robot and the environment in virtual reality. Although this created an engaging experience, it also revealed an important limitation, because visitors were separated from the real exhibition space and from the physical robot on display. RHINO-AR addresses this reality gap by placing a virtual reconstruction of the robot directly into the real museum space. Implemented on a Magic Leap~2 headset using Unity, our system combines real-time environment meshing with interactive visualizations of LiDAR sensing, traversability, and path planning to make otherwise invisible robotics processes understandable to non-expert visitors. We evaluated RHINO-AR in a two-day museum study with 22 participants, assessing usability, technical performance, satisfaction, conceptual understanding, and preference comparison to RHINO-VR. The results show that RHINO-AR was well received, effectively conveyed key navigation concepts, and generally preferred over the VR exhibit due to its stronger physical grounding and increased realism.
