1. 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.

13. An apparatus comprising
a processor, and a memory including computer program instructions, the memory and computer program instructions being configured to, in cooperation with the processor, cause the apparatus to: -
convert at least one of 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; cause 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 detect a moving of a touch on the display by a predetermined distance in a predetermined direction before causing the actuator to move the display 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 the 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 sixth dot. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 29)
