Abstract
An apparatus can include a processor; memory operatively coupled to the processor; a touch-sensitive display operatively coupled to the processor; and a tactile braille panel operatively coupled to the processor where the tactile braille panel overlays at least a portion of the touch-sensitive display.
Claims14
An apparatus comprising:
- a processor;
- memory operatively coupled to the processor;
- a touch-sensitive display operatively coupled to the processor;
- a tactile braille panel operatively coupled to the processor wherein the tactile braille panel overlays at least a portion of the touch-sensitive display;
- and
- braille rendering circuitry that, in a braille mode, renders braille characters to the tactile braille panel, that receives touch input for sensed touches of the rendered braille characters, that determines a touch rate based at least in part on the touch input, and that controls a rendering rate of braille characters to the tactile braille panel based at least in part on the determined touch rate.

A method comprising:
- rendering information to a touch-sensitive display;
- in a braille mode, rendering braille characters to a tactile panel that overlays at least a portion of the touch-sensitive display;
- determining a touch rate based on receiving touch input for sensed touches of at least some of the rendered braille characters;
- and
- based at least in part on the touch rate, rendering additional braille characters to the tactile panel.
