Touchscreen tablet devices (such as the Apple iPad, the Google Nexus 10 or the Microsoft Surface) present an interesting challenge to interaction designers: they are not quite handheld like their smartphone cousins, though their form factor affords usage away from the desktop and other surfaces. They can accept multitouch input and, by extension, bimanual input; however, a user will often have to dedicate one hand to holding or supporting the device, constraining their ability to interact fully using two hands on the touchscreen. In general, the opportunities for bimanual input are constrained by the reach of the user's supporting hand. The challenge for designing bimanual interaction techniques for tablet devices is to enable coordinated two-handed input while the user is comfortably holding the device. My Ph.D Research explored the use of non-dominant hand isometric force (pressure) input to support interaction design in this context.
I'm currently writing up my thesis. I expect to submit at the beginning of July and complete my viva this summer.
