Smart watches provide users with access to many applications directly from their wrists, without the need to touch their smartphones. 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, the authors introduce their interaction design and an optimized alphabetic layout for smart-watch text entry, 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 study participants indicates that reasonable quality and speed is achievable on a smart watch and encourages future work in this area. This article is part of a special issue on wearable computing.

We present a prototype for indoor navigation using Augmented Reality that uses interior features to determine the user's location and provide navigation instructions. We test our prototype in a simulated physical shopping mall environment and find that AR-based navigation can provide usability advantages in indoor locations, particularly where targets are located on different floors. We conclude by recommending further work in presenting interior navigation instructions using AR.

Smartwatches now 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 smartwatch text entry, an optimised alphabetic layout and present a prototype implementation together with preliminary user feedback. While raising some problems, the feedback gives indicates that reasonable quality and speed is achievable on a smartwatch and encourages our future work
