US Patent 10346038 Braille data entry using continuous contact virtual keyboard

A first touch gesture is sensed at a subset of a set of six Braille dot touch points at a virtual Braille keyboard. The first touch gesture corresponds to a Braille character. A second touch gesture is sensed that concurrently touches each of the six Braille dot touch points in the set of Braille dot touch points. A contact with a layout of the virtual Braille keyboard with at least one Braille dot touch point is continuously maintained while transitioning from the first touch gesture to the second touch gesture. In response to the second touch gesture, the Braille character is accepted.
