People with visual impairments are even cautious about pour water. Therefore, we designed a cup that allows people with visual impairments to measure the height of water with only a touch.
Using the shape of braille, which is familiar to them, three round shapes were added according to the height of the water.
This round cotton is thinner than rubber and thicker than paper, and when there is no water, it goes inside.
When the water goes over a certain height, it sticks out tight in the front. People with visual impairments can tell the height of water through the touch of their fingertips with these changes in round circles.
