This is one of those ingenious inventions that makes us ask why no one has thought of it before. Haptica is the name of a wrist watch especially created by American designer David Chavez with a braille dial. The truth is there are already several kinds of watches for the visually impaired, but they are nothing more than conventional devices in which you can touch the watch's hands in order to know the time. Now, thanks to a crafty mechanical system, the Haptica is the first watch to write the time in braille in its dial.
The watch's box has two parallel, lateral borders that create a channel that leads the firgers unto a reading surface. This surface is no more than a set of rotating disks with a braille code incision that is actually the hours and minutes numbers. It is essentially a classic mechanical system in watchmaking and the designer's merit lies in the fact that he was able to adapt it to this use, in particular. David Chavez's idea was duly honoured with a Spark Award, and, while we are on the subject, you can check out the rest of the winners here).
