Can you handle it?: bimanual techniques for browsing media collections on touchscreen tablets.

Touchscreen tablets present an interesting challenge to interaction design: they are not quite handheld like their smartphone cousins, though their form factor affords usage away from the desktop and other surfaces. This means that users will have to find ways to support the device that often require one hand to hold it, constraining their ability to use two hands on the touchscreen. Our ongoing work explores the possibility of using novel input modalities mounted on the tablet to enable simultaneous two-handed input while the user is holding the device. This paper presents a bimanual scrolling technique that splits the control of scrolling speed and scrolling direction across two hands using a combination of pressure, physical dial and touch input.
