 The design and preliminary evaluation of a sliding contact Braille display for early learning. Currently available single-cell Braille displays do not allow sliding contact between the text and the reading finger. We have designed a sliding contact single-cell display, allowing early learners to learn both jumbo and standard Braille. The test results show an accuracy of 96.2% in reading letters and 89.7% in reading words. Come and check out more of our results.
