The augmented reality system comprises a display and is arranged to determine the user's current position, to determine a safe or optimum path from the user's current location to a desired destination, determine if there are any hazards or unmapped areas, provide an augmented reality overlay over a user's field of vision which visually masks or obscures any hazards or unmapped areas which might distract, attract or confuse the user, and the system overlays a series of transverse bars, images or other visual cues which appear to the user to be located on the ground in front of the user and which act to prompt the user to step forwards and follow the determined safe or otherwise optimum path from the user's current location to the desired destination. The display may be a headset or glasses. Where transverse bars are overlaid, they may be adapted in proportion with a user’s height or gait. The system may use gamification and reward points or other feedback after the user has progressed walking over or towards one or more of the visual cues. The apparatus may assist a user with Parkinson’s disease achieve increased mobility by navigating a particular space when experiences freezing of gait (FOG). Multiple people may be able to use systems in the same area. The system may be used with or without a nurse or practitioner.
