 Hello to everyone, my name is Giuseppe Melfi and I work at Kalswe Institute of Technology. I will present you our work on AudioTactile Reader, an interactive system for students with blindness to explore digital document on a 2D haptic device. Graphic representation, like flow charts, are challenging for students with blindness. Possibility to improve the accessibility is provided to the student a textual description of the graphics. But in this way, no access to the original document is provided and explore diagram to discover information independently is missing, but it is an important part of the learning process. A better solution is provided also tactile graphic, but they are not easy to read and they are not interactive. For this reason, we developed an AudioTactile Reader and interactive system based on two dimensional pin matrix device with a touch surface on it and an application running on a Windows laptop. In this slide, we can see on the left an example of a PDF input file and on the right we have the tactile counterpart of the document created with our system. The text is replaced with tactile symbols and the user can listen to the content with a double tap on this symbol. Another feature of the system is the filtering. In this example, we removed the text field and also the element in orange and green. The last feature developed was Zoom to improve the readability of complex graphics and documents. We tested the prototype in a user study with four blind participants and in the first phase, we evaluated three different documents. In the second phase, we used a more realistic lecture material and we compared the AudioTactile Reader with the embossed tactile graphic methods that was used as baseline. The results were quite interesting and as in phase one, 91% of the questions were correctly answered by the participants and both the feature filter and zoom was ranked with a good score. In phase two, AudioTactile Reader performed better results compared to the baseline. Thank you for your time.
