Text input on a smart watch

Smart-watches provide users with access to many applications on smartphones direct from their wrists, without the need to touch their smartphone. While applications such as email, messaging, calendar and social networking provide views on the watch, there is normally no text entry method so users cannot reply on the same device. Here we introduce requirements for smart-watch text entry, an optimised alphabetic layout and present a lab evaluation of an implemented prototype using the OpenAdaptxt engine on a Sony SmartWatch 2. While raising some problems, the feedback from our participants indicates that reasonable quality and speed is achievable on a smart-watch and encourages our future work
