Osaka University have created what they've called the Paranga -- a device that fulfills the lack of tactile feedback of page turns when using an e-reader. It's got a built in sensor that detects when the book is being bent and will rotate a roll of paper strips against your thumb. The force exerted against the device will control the speed of the paper roll. Although it's not accurate enough to turn one page at a time, the researches believe that if foil is used instead of paper, the voltage will be discharged as soon as a page is turned, ensuring single-page accuracy.
