Abstract:
An apparatus and a method for a walking aid are disclosed. The walking aid includes a walker having a frame configured to extend about a user of the walker to at least partially support the user and to facilitate the user progressing along a path from a current step to a next step while at least partially supported by the walker. A swivel mount is supported by the frame. A light source is connected to the swivel mount. The light source is configured to project a visual cue on a projection surface in the path between the current step and the next step to trigger the next step by the user. A controller is configured to adjust a visual property of the visual cue for use under indoor conditions and outdoor conditions.
