Design and Evaluation of a Multimodal Feedback VR Exergame for Individuals with Low Vision

Abstract

People with partial vision loss often face limitations in psychological healing and physical exercise due to insufficient visual ability and inadequate interaction design. Existing solutions largely focus on superficial accessibility improvements, while most VR systems remain visually dominant, limiting usability and experience for this group. To address this gap, we present Light of Sound Healing, a VR exergame designed for partially sighted users. Guided by multisensory substitution interaction, the system employs spatial audio as the primary medium for navigation and interaction, translating auditory cues into directional and distance signals. Players locate audio targets and perform physical actions within an immersive environment. The design integrates inclusive design, serious games, and art therapy, with progressive challenges introduced through variations in target size, quantity, and movement. Findings indicate that a multimodal feedback system combining spatial audio, visual cues, and haptic vibration enhances perception and immersion. This approach highlights the potential of auditory-centric interaction for accessible VR and digital rehabilitation. Overall, this study proposes an auditory-centered VR interaction framework that improves engagement and movement experience for visually impaired users, while offering design insights for inclusive immersive systems.
