A study on the use of semaphoric gestures to support secondary task interactions

We present results of a study that considers (a) gestures outside the context of a specific implementation and (b) their use in supporting secondary, rather than primary tasks in a multitasking environment. The results show semaphoric gestures offer significant benefits over function keys in such interactions, and how our findings can be used to extend models of design and evaluation for ubiquitous computing environments that support multitasking.
