Reflect-AR: Insights into Mirror-Based Augmented Reality Instructions to Support Manual Assembly Tasks

  • Manual assembly tasks can be difficult and tedious without assistance. Here, augmented reality (AR) can help to ease the task load and lower the time and error rates by interactive in-situ instructions. Such approaches are often implemented by video or optical see-through AR. In order to test a system that is as low-threshold as possible and easy to implement, we developed a prototype with a mirror display supplemented by a RGB-D camera and evaluated it against an well-established AR HMD (HoloLens 2). For this purpose, in our study 10 participants placed 3D printed bricks via both technologies. The quantitative and qualitative analysis revealed that the fulfillment of this task with a professional, established product AR HMD yet remains unmatched in terms of the time required, error rate, usability and task load due to the prototype status and the remaining technical shortcomings. However, the mirror display setup prototype met with interest from the participants as a novel, but unfamiliar and thus more difficult to use way ofManual assembly tasks can be difficult and tedious without assistance.

Furthermore, we report implementation challenges and advises. The empirical insights of our prototype and the first-time comparison to an established AR HMD aims to foster refining future work with half-silvered AR mirrors as an little researched field and many different fields of application.show moreshow less
