Patent ID: 8388346

Claim:
A method comprising: converting at least one of a textual information and graphical information into instructions for a sequence of pulses representing the information, wherein the instructions for the sequence of pulses comprise instructions for a sequence of groups of subsequent pulses; causing a single actuator, which is configured to convert energy into a movement, to move a display in the sequence of pulses according to the instructions; and detecting a moving of a touch on a display by a predetermined distance in a predetermined direction before causing the actuator to move the display according to instructions for a respective next group of pulses, wherein each group of pulses represents one dot of a six-dot Braille character, wherein the predetermined direction comprises a vertical downward direction between causing the actuator to move the display according to the instructions for the groups of pulses for the first and the second dot, a vertical downward direction between causing the actuator to move the display according to the instructions for the groups of pulses for the second and the third dot, a vertical upward direction between causing the actuator to move the display according to the instructions for the groups of pulses for the third and fourth dot, a vertical downward direction between causing the actuator to move the display according to the instructions for the groups of pulses for the fourth and the fifth dot, and a vertical downward direction between causing the actuator to move the display according to the instructions for the groups of pulses for the fifth and the sixth dot.
