PenScreenSix is designed to run on a 7″ tablet. Many of the tests can also be run on a mobile phone with a much smaller screen, typically 2.5″ diagonal. Does this make a difference? Jimmy Jansen, Joris Verster at Utrecht University and their colleagues have completed a study comparing the two platforms in a crossover design. Performance was very similar, and results correlated well between the different size devices. Click here to see the presentation of the study. (c) The authors.
