Path Finder - a shoe attachment to alleviate 'freezing of gait' in Parkinson's

Path Finder is a shoe attachment that provides visual cues to help people with unsteady and irregular gait. This is particularly helpful to people with neurodegenerative diseases such as Parkinson's disease, who commonly suffer from freezing of gait (FoG), a symptom causing an individual to feel as if frozen to the ground.

Path Finder projects a horizontal line on the ground in front of the user, at a set distance from the feet. This gives the wearer a visual cue to step across, and acts as an external stimulus to trigger walking. The visual cue is projected from each foot in turn. The device on the left foot projects in front of the right foot and vice versa. Each cue is projected from the foot only once placed on the ground, thus producing a static cue.
