ABSTRACT
The ongoing miniaturization of computing devices enabled smart watches with capabilities almost on par with smart phones. Due to immanent size restrictions smart watches require specifically designed input and output techniques. In particular, entering text is often needed when interacting with computers but the watches' small size excludes common input techniques. In this paper we propose a text entry technique using a touch sensitive wristband. Using the wristband requires no screen space besides displaying the current character and might enable cheaper devices. In an experiment we compare a linear keyboard and a multitap keyboard layout. We show that users type faster and make fewer errors using multitap. We argue that the inexpensive sensors enable the integration in low cost wearable watches that require text entry occasionally.

Text Entry on Tiny QWERTY Soft Keyboards
CHI '15: Proceedings of the 33rd Annual ACM Conference on Human Factors in Computing SystemsThe advent of wearables (e.g., smartwatches, smartglasses, and digital jewelry) anticipates the need for text entry methods on very small devices. We conduct fundamental research on this topic using 3 qwerty-based soft keyboards for 3 different screen ...
A text entry technique for wrist-worn watches with tiny touchscreens
UIST '14 Adjunct: Adjunct Proceedings of the 27th Annual ACM Symposium on User Interface Software and TechnologyWe consider a text entry technique for wrist-worn watches with inch-scale touchscreens. Most of the watches which are commercially available, for example, Galaxy Gear, Omate, etc., have around 1.5-inch touchscreens that is too small for the shrinked ...
