Automatic calibration of braille interface

A non-transitory computer readable medium (CRM) comprising instructions that, when executed by an apparatus, cause the apparatus to:

• accept, from an interface equipped to the apparatus, a sequence of finger touches on a plurality of regions of the interface, the sequence of finger touches corresponding to one or more braille characters;
• sense, from the input, distances between individuals of the finger touches on different regions of the plurality of regions;
• and
• map, from the sensed distances, individuals of the plurality of regions to corresponding dots in a 2×3 braille matrix.

An apparatus, comprising:

• a user interface responsive to multiple simultaneous finger inputs;
• a processor;
• and
• instructions executable by the processor to cause the processor to:
• accept, from an interface equipped to the apparatus, a sequence of finger inputs on a plurality of regions of the interface, the sequence of finger inputs corresponding to one or more braille characters;
• sense, from the inputs, distances between individuals of the fingers on different regions of the plurality of regions;
• and
• map, from the sensed distances, individuals of the plurality of regions to corresponding dots in a 2×3 braille matrix.
