This is a silicone cup specially designed for the blind. The non-slip mat at the bottom is a hollow air bag containing a small amount of gas. There are three indentations on the airbag. When the water cup starts to add water, the weight of the cup body will increase and the airbag below will be squeezed out. Depending on the amount of water added, the number of extruded dots is also different. Blind people can sense the water content in the cup by touching the prominent dots.

I think this time is the design of egg pain. The blind can't see it and it's not the deaf. The water in the cup has weight. Pick up the cup and feel the weight. You don't know if you can't shake it.
Not bad, not bad
You are 16 years late. One of the Red Dot Awards is based on this principle (hug
bravo !!! Wouldn't it be better to put the bumps in the middle of the cup through the connecting device?
Are you interested in playing with me
Blind people should be very sensitive to the feeling of falling touch on their hands. The weight estimation of the water in the cup should not be a problem. Even if a normal person picks up the cup for a long time without looking at it, he can estimate the amount of water in the cup. Moreover, the shape of the cup with a narrow upper and a wide lower cup is not conducive to grasping and picking up. It is better to pick up these three bumps directly.
I think for blind people, we should solve the problem of preventing being knocked down by mistake.
The display of the product feels a little less.
Good idea!
