Now, researchers at Queen's University's Human Media Lab have taken this to another level, creating a prototype device called ReFlex, with a flexible display and advanced tactile feedback.
Central to the new device are what the researchers call bend gestures. Bending the display down to the right causes virtual pages to flip from the right to the left of the display, just as they would if you were holding a book. The more you bend the panel, the faster the pages flick by.
The concept handset also has highly detailed vibrations across the display, designed to enhance the sensation of flipping through the pages. According to the researchers, those vibrations, combined with the passive force feedback of bending the panel, create a realistic simulation of physical forces. In other words, it really fells like you're flipping through the pages of a book.
