ring cooking pot / pot

I wanted to improve the pot which is difficult for the visually unabled person to use. Touch1_The handle is surrounded by the lid of the pot. Even though a person can’t see, one can find the position of the handle easly and safety. Since the handle is on the side of the lid instead of the middle of the pot, on can avoid the possibility of touching the lid which is extremely hot. Touch2_One can pour water in the pot as much as he wants by sensing the braille line which informs certain quanitys of the water. Hearing_One can know whether the water is boiled or not by the sound the pot makes when the boiled steam passes the hole of the pot.
