Touch Survey: Comparison with Paper and Web Questionnaires
  We developed a prototype of touch-based survey tool for tablets and conducted an experiment to compare interaction patterns of touch-based, PC-based, and paper-based questionnaires. Our findings suggest that a touch-based interface allows users to complete ranking questions easily, quickly, and accurately although it can increase the time to complete a location input task for well-known, prominent locations.
