*** begin quote ***

The augmented reality glasses simulate an effect called kinesia paradoxa: the triggering of normal walking behavior in akinetic Parkinson’s patients by the placement of physical obstacles at their feet. Sometimes such cues exist naturally, such as black and white tiles placed evenly on a floor. The black tiles appear as objects to avoid, or as guides, and trigger a reflex of landing the feet between the black spaces. Walking up regularly spaced objects like stairs triggers the same effect, and can “un-freeze” a person who otherwise has problems walking with a normal gait. Presenting virtual objects and abstract visual cues moving through the patientýs visual field at speeds that emulate normal walking can also achieve this effect.

When I read this i had a “Great Brother Jasper’s Ghost!!!” moment.

My Mom has just past. As she aged, she suffered terribly with Parkinson’s.

Growing up, she had spent a lot of money on black and white tiles through out the apartment. Maybe it was her way, even without knowing it, that she was compensating.

Wish I could tell the author. It might help him to another breakthrough.

I find this an interesting explanation.
