A Spoken Tablet Accessibility Device for Disabilities Students

Can we invent a spoken tablet for blind students to integrate them into learning technology environment where blind student with certain touch can hear a sound directed him to do something such as search , drawing and browsing topic. I think this way help disabilities students to take part in our modern life and feel him happiness as to do something that connected him into peers around the world and they can express their hopes and ideas , using spoken tablet. Can we discuss this matter as bloggers and technologists? Please! tell me about your point of view? can we achieve something like that?
