Tactile graphics with a voice demonstration.

ABSTRACTTextbook images are converted into tactile graphics to be made accessible to blind and low vision students. The text labels on these graphics are an important part of the image and must be made accessible as well. The graphics usually have the labels embossed in Braille. However, there are some blind and low vision students who cannot read Braille and need to be able to access the labels in a different manner. We present Tactile Graphics with a Voice, a system that encodes the labels in QR codes, which can be read aloud using the application, TGV, we developed. TGV provides feedback to support the user in scanning the QR code and allows the user to select which QR code to scan when multiple are close together.
