The original watch is a Diesel digital watch. The face has been re-designed. Two issues are addressed in this re-design:
1. Existing wristwatches for the visually impaired are analog. The user is meant to open the face and feel with their fingers what time it is. I feel that this is a 'shoe-horn' design. Rather than creating something that is merely acceptable, why not create someting that is desirable? Though it may not be seen by the user, it will be seen by others, which adds to the user experience by creating an object of intrigue and envy.
2. In order to 'properly' display time in braille, one would need 9 characters (essentially a matrix of 3X18 dots). I feel that this can be made into a shorthand form, consisting of only the relevant information, layed out in an intuitive way, from left to right, top to bottom, reducing down a matrix of 4X4.
