Until now, all the concepts for books for the blind that I know of were, by and large, a special reissue in which either the pages are displayed in Braille or the text is voiced by voice. In general, if you consider a book as a device, then designers have always sought to create new devices. But the Chinese team in the person of David Lee, Yuna Kim and Hansub Lee proposed to invent nothing new, but to modernize the old one. In their concept of Haptic Reader, the book remains typed in the usual font for the sighted. New is only a translucent bookmark-scanner: you put it on the page and braille pimples appear on the gadget. Hmm ... now it remains to come up with a translator who works on the same principle.
