Mobile capture for wearable computer usability testing

The-mobility of wearable computers makes usability-testing; difficult. In order to fully understand how a user interacts with the wearable, the researcher must examine, both the user´s direct interactions, with the, computer, as well as the external context the user perceives during their interaction. We present, a tool that augments a wearable computer with additional hardware and software to capture the information needed to perform a usability study in the field under realistic conditions. We examine the challenges in doing the capture and present our implementation. We also describe VizWear a tool for examining the captured data. Finally, we present our experiences using the system for a sample user study
