We present FlexView, a set of interaction techniques for Z-axis navigation on touch-enabled flexible mobile devices. FlexView augments touch input with bend to navigate through depth-arranged content. To investigate Z-axis navigation with FlexView, we measured document paging efficiency using touch, against two forms of bend input: bending the side of the display (leafing) and squeezing the display (squeezing). In addition to moving through the Z-axis, the second experiment added X-Y navigation in a pan-and-zoom task. Pinch gestures were compared to squeezing and leafing for zoom operations, while panning was consistently performed using touch. Our experiments demonstrate that bend interaction is comparable to touch input for navigation through stacked content. Squeezing to zoom recorded the fastest times in the pan-and-zoom task. Overall, FlexView allows users to easily browse depth arranged information spaces without sacrificing traditional touch interactions.
