Hi ZucchiniFlower,
You do not wear the devise all the time, only 30 minutes a day. After that you have residual memory. You can imagine, feel you are seeing the tiles and your body without effort remembers how you were walking while using the glasses. I have had the devise for a very short time and saw already changes.

I had tried using the tiles in our building and the lines on the sidewalk but there is a problem. They have a fixed size. You can only make steps the size of the tiles. With the devise your stride can change, tiny steps or long steps!

The patient (My husand) focuses on the speed and length of his steps, on his posture, on where his place their foot (right in front of them, not all over the place). Because of the feedback he got a sense of how badly he was walking.
