ABSTRACT
Ultra-small touch screen devices tend to suffer from occlusion or the fat finger problem owing to their limited input area. Callout design, a design principle that involves the placement of a callout in a non-occluded area in order to display the occluded area, could eliminate occlusion. However, callout designs for ultra-small touch screen devices have not yet been explored. In this study, we conducted an experiment to examine eight callout designs for ultra-small touch screen devices. The results show that the selection speed was higher when the content of the callout was changed continuously, the error rate decreased when a pointer was displayed to indicate the touched position within the callout, and the workload decreased when the content was changed continuously. Further, the score that subjectively evaluates the performance decreased when the position of the callout was fixed.

Flickey: Flick-Based QWERTY Software Keyboard for Ultra-small Touch Screen Devices
Human-Computer Interaction. Interaction TechnologiesAbstractUltra-small touch screen devices (e.g., smartwatches) are required to be small and lightweight so that they can be worn on the body with no frustration. For this reason, users often have difficulties in selecting the correct keys, and thus ...
Exploring tilt for no-touch, wrist-only interactions on smartwatches
MobileHCI '16: Proceedings of the 18th International Conference on Human-Computer Interaction with Mobile Devices and ServicesBecause smartwatches are worn on the wrist, they do not require users to hold the device, leaving at least one hand free to engage in other activities. Unfortunately, this benefit is thwarted by the typical interaction model of smartwatches; for ...
