ABSTRACT
Navigating the environment can be challenging, especially when faced with vision or hearing limitations, such as darkness and visual impairments. To address this issue, we propose using electrical muscle stimulation (EMS) to convey spatial information and assist users in avoiding obstacles. We map direction to EMS channels and distance to current intensity, with force-feedback for closer proximity and tactile EMS feedback for greater proximity. An experimental study (n=12) was conducted to evaluate the concept and gain insights into the qualitative perception of EMS. Participants were able to accurately estimate encoded distance (85.7% accuracy) and direction (99.5% accuracy). Our findings demonstrate the feasibility and effectiveness of using tactile and force feedback EMS to convey spatial information comprehensibly.
