HeliCoach: An Adaptive Orientation and Mobility Training System in a Drone-based 3D Audio Space

We present HeliCoach, an adaptive O&M (orientation and mobility) training system to help visually impaired people to gain audio-orientation ability efficiently. HeliCoach is a mastery-based adaptive learning system consists of three components: A drone-based physically simulated 3D audio space, a UWB (Ultra-Wide Band)-supported assessment system, an intelligent belt with haptic feedback as training scaffolds. We evaluated the acceptability and efficiency of HeliCoach on both blindfolded sighted participants and visually impaired participants in an audio-orientation task. The results showed that HeliCoach was efficient and interesting. Thus, We believe HeliCoach can be applied to many simulated 3D audio space related task to train people more efficiently.
