Abstract
Gesture keyboards represent an increasingly popular way to input text on mobile
devices today. However, current gesture keyboards are exclusively unimanual. To
take advantage of the capability of modern multi-touch screens, we created a novel
bimanual gesture text entry system, extending the gesture keyboard paradigm from
one finger to multiple fingers. To address the complexity of recognizing bimanual
gesture, we designed and implemented two related interaction methods,
finger-release and space-required, both based on a new multi-stroke gesture
recognition algorithm. A formal experiment showed that bimanual gesture behaviors
were easy to learn. They improved comfort and reduced the physical demand relative
to unimanual gestures on tablets. The results indicated that these new gesture
keyboards were valuable complements to unimanual gesture and regular typing
keyboards.
