Abstract

A wearable computer interface with split button configuration was constructed using Arduino Lilypad components on the front of a vest with the goal of assessing its usability in an activity involving at least one hand. A sample of twelve men and eight women ages 18 to 62 participated in a usability study of the vest. The activity chosen for this study was a typing test during which users would control a media player remotely with the vest. The usability measures included ease of use, performance of the interface as determined by accuracy rates and time to task completion for both button pressing and the typing test, and comfort. Results indicate the participants found the vest easy to learn and use with no significant effect on the accuracy of the typing activity, but they often needed visual cues to locate the controls. Based on these findings, we offer suggestions for improving the design of the interface and future work we want to pursue after the modifications.
