In this video, designer Mileha Soneji recounts her astonishment at watching her uncle — who has Parkinson's and normally uses a walker — ascend and descend the stairs with ease. She learned that when it comes to Parkinson's, continuous movements like riding a bike or taking the stairs are easier to negotiate than "regular walking". When she then experimented with applying a fake, painted staircase to a flat surface, her uncle could glide over it with little trouble.
The crux of Soneji's talk is about seeking simple, low-tech solutions, but we found the prospect of building a high-tech version irresistible. We thought: What if we take this staircase illusion and apply it anywhere in the world?
