“…Commercially available AR devices show content in central vision and are therefore not suitable for our approach of providing visual cues in the periphery. Thus, we used our own head-mounted display toolkit for peripheral vision -MoPeDT (Albrecht et al 2023). MoPeDT is a headset toolkit to exclusively augment peripheral vision using a custom 3D-printed headset and off-the-shelf electronic components.…”

Falls are a major health concern, especially for elderly people. Existing augmented reality (AR) and virtual reality (VR) solutions for fall prevention aim to improve balance in dedicated training sessions. We propose a novel AR prototype as an assistive wearable device to improve balance and prevent falls in daily life. We use a custom head-mounted display toolkit to present augmented visual orientation cues (AVOC) in the peripheral field of view. The cues provide a continuous space-stationary visual reference frame for balance control using the user's tracked head position. In a study, users performed a series of balance trials to test the effect of the displayed visual cues on body sway. Our results showed that body sway can be reduced with our device, indicating improved balance. We also showed that superimposed movements of the visual reference in forward-backward or sideways directions induce respective sway responses. This indicates a direction-specific balance integration of the displayed cues. Based on our findings, we conclude that artificially generated visual orientation cues using AR can improve balance and could possibly reduce fall risk.

“…To test our idea, we used a custom-built HMD (Albrecht et al 2023) and conducted a study to test the effects of the device on balance as a proxy for its functionality. Humans show small oscillations when standing upright (spontaneous sway), which is considerably larger with eyes closed as compared to eyes open.…”
