Try this, blindfold yourself and pour a glass of water without spilling it over. Ok, make this tougher, fill in exactly ¾ th cup. Tough? Yeah, that’s how hard it is for the blind people to fill in mugs of beverages without spilling. Dipping the pinkie to anticipate the levels is ok for cold stuff, but what about scalding hot coffee! The Braun Bell Mug has 3 indicative levels on the handle and liquid-level sensors within the mug. The blind folks only need to choose their levels and keep pouring till the bell sounds.
