 Hello, we are going to talk about tactile illustrated books and new technology for blind children. So first, let's talk about books. It is known that access to books for young children is crucial for the development of early literacy, and that pictures make it easier for children to understand the story. However, if there is a broad choice of books for sighted children, we cannot say the same for blind children. There are only a few tactile books accessible and these books are generally expensive and fragile due to excessive handling. Now, how new technology could improve access to tactile illustrated books for blind children? Pinary tablets are made of pins that can go up and down to display information. The use of these technologies could make it possible to illustrate several books with the same device, and parents, teachers, or even children could easily create and update pictures. However, it seems complicated to display pictures with many details on these devices. And that's why we use pictograms. As you can see in the pictures, what we called resolution, that is the size of the pin and the gap between two pins may vary. So we compared two types of dotted pictograms based on existing tablets. Pictograms based on low-resolution tablets made of 4mm dots with 4mm gaps, and pictograms based on high-resolution tablets made of 1mm dots with 1mm gap. And we compared these dotted pictograms with line pictograms. To do that, we created three lists of ten words equivalents in their usage frequencies and illustrated them in the three illustration conditions, which were line pictograms, low-resolution pictograms, and high-resolution pictograms. And then we proposed to young blind and blind-folded children to recognize these pictograms. Our study showed that for blind and blind-folded sighted children, line pictograms were better recognized than dotted pictograms, whether they were high-resolution or low-resolution. We also observed an effect of the resolutions of the tablet with high-resolution pictograms being better recognized than low-resolution pictograms. And even though lower than with line pictograms, recognition rates for high-resolution pictograms can still be quite high, up to 70% for blind children. So these tablets could be useful to illustrate books for blind children. And because we observed an effect of the resolutions of the tablets, future studies should look at the haptic perceptions of dotted patterns more deeply. Well, thank you for listening and I would be happy to answer any question you might have.
