Sa'o.

“When preparing food for my baby, I have no way of making sure I put the exact amount in the bottle.”

- Ane, a mother who suffers from total blindness.

Blind people currently have insufficient products in the market designed for them. Sa'o is a liquid measuring assistant to help blind people prepare exact amounts of liquid. The ultrasound sensor on the removable cap constantly measures the distance to the surface of the liquid. This distance data is then used to easily calculate the precise amount of liquid in the vase. The head has an ON/OFF button and an AUDIO button which when pressed, communicates the amount of liquid outloud. The head of the jar contains the circuitboards and can be easily removed to charge it up or clean the jar.
