Coffee Mug for the Blind Chimes When Full

It can be fascinating to consider how you would perform certain daily tasks with impaired senses - and this one is indeed a head-scratcher. How do blind people fill coffee mugs without overfilling? Feeling the weight of the liquid would be difficult because the mug already weighs so much; a paper or styrofoam cup may be easier for that reason. It's also possible that single-serving coffee machines are a common method. Well, however they may do it now, designers Sang-hoon Lee and Yong-bum Lim have a solution that's probably easier: a mug that chimes when it's full. It seems simple, straightforward, and actually capable of being produced. And most importantly, it makes a situation more usable for some of the people who need it most.
