Loki

Abstract

Figure 1: An instructor (orange) teaching a learner (green) how to play a chord on a guitar in mixed reality using Loki. The learner, who is in VR (d), observes the instructor who is in AR (a) demonstrating the chord. The learner uses spatial annotations to ask a question about the performance. Then, both enter AR and the learner begins to practice while the instructor provides occasional coaching (b, e). Lastly, the learner performance is recorded, and both instructor and learner review the recorded performance in VR and discuss the errors (c, f).
