Blind people cannot see.  Without the sense of sight, it is particularly difficult to pour a glass of water or a mug coffee.  It is even more trying to pour an exactamount of liquid into a container.  Enter ‘The “Braun” Bell Mug’ concept by Sang-hoon Lee and Yong-bum Lim.  This concept mug “has 3 indicative levels on the handle and liquid-level sensors within the mug” that allow blind people (or those with extremely poor vision) to pour precise amounts of liquid into a mug.  The mug handle has three rigid buttons on its surface; all a person has to do is select one of the three levels and pour away.  Once you have poured the desired amount, the mug emits a bell sound.  Neat, huh?  This is surely a product worthy to pass as a final, tangible item to be manufactured.  Check out the gallery of images below for some concept product shots and directions.
