BendFlip: A Flexible Reading Apparatus

Abstract

We present recommendations for the design of flexible electronic book readers, based on an empirical evaluation of form factors and input techniques in a single page navigation task. Capacitive touch, pressure, and bend sensors are compared on rigid and flexible devices using a prototype electronic book reader. Results from the evaluation of input techniques suggest flexible designs do not perform significantly worse than rigid designs, and bend gestures perform as well as button presses in flexible form factors. Capacitive touch sensors may have decreased performance on flexible devices. We conclude by presenting recommendations for the design of future flexible e-book readers.
