Concave & Convex / Concave & Convex Braille Cup

Concave & Convex

When pouring water, the blind needs to estimate the depth of water by putting his finger into the glass. What is worse, if the water is too full, it might spill over.
"Concave & Convex" solves these problems. When a blind man needs to pour a glass of water, he can easily find the Braille pits, which shows the amount of water, on the surface of the cup to determine how much water he needs to drink. With the water pouring into the glass, the pits will gradually become bumps when the water is higher than them. Thus, he can know whether the water is enough for him according to the changing Braille.
