  • Navigation aid for refreshable braille display and other text products for the vision impaired
    Patent number: 6987467
    Abstract: A navigation aid for a refreshable Braille display and similar products for the visually impaired. A navigation wheel is located adjacent at least one end of the refreshable Braille display. Rotation of the wheel by an increment moves the displayed text forward or backward by a predetermined increment, such as by one word, or one line or one paragraph. In a preferred embodiment, the function performed by rotating the wheel can be changed by depressing the wheel. A separate navigation wheel may be located at opposite ends of the refreshable Braille display and the two navigation wheels may perform the same or different functions when rotated.
