ABSTRACT

Advanced mobile phones, such as Smartphones and Pocket PC phones, can potentially provide cost-effective ubiquitous IT access. Towards evaluating their potential and discovering their usability problems, we distributed state-of-the-art Pocket PC phones to 10 mobile users and employed a triangulation of research methods to study their usage for two months. Our research methods included qualitative inquiries in the form of focus groups and structured interviews, and quantitative measurements in the form of in-situ logging. Unlike most previous studies that focused on a single design aspect, our study provides a comprehensive picture regarding the holistic usability of advanced mobile phones.
