My interests are at the intersection of mobile computing and HCI. I have been a wearable computer user since 1999, and I am very interested in the interaction challenges brought about by mobile device usage in everyday situations.
One thrust of my research has been examining the fundamental input and output interaction issues of using mobile devices. I have conducted several longitudinal evaluations of the Twiddler one-handed chording keyboard and the mini-QWERTY keyboard. I have also begun to examine other interaction aspects such as using different types of mobile displays. Furthermore, I have begun to evaluate interaction in more realistic everyday situations, such as while in motion or on the go.
I am also interested in applying mobile technology to enhance everyday life. My dissertation work explored how improved input could be utilized to enhance conversations. This work was inspired by wearable computer users that often use a one handed keyboard and head-up display in support of their conversations. I developed the dual-purpose speech interaction technique as a mechanism to reduce manual input by using speech recognition of the user's conversation with another person. I am also currently exploring how individual hand-held mobile devices might be used for media sharing to augment face-to-face social interactions.
