    Deconstructing the Touch Experience
    (ACM, 2013) Watson, D.; Hancock, M.; Mandryk, R.L.; Birk, M.
    In this paper, we evaluate the performance and experience differences between direct touch and mouse input on horizontal and vertical surfaces using a simple application and several validated scales. We find that, not only are both speed and accuracy improved when using the multi-touch display over a mouse, but that participants were happier and more engaged. They also felt more competent, in control, related to other people, and immersed. Surprisingly, these results cannot be explained by the intuitiveness of the controller, and the benefits of touch did not come at the expense of perceived workload. Our work shows the added value of considering experience in addition to traditional measures of performance, and demonstrates an effective and efficient method for gathering experience during inter-action with surface applications. We conclude by discussing how an understanding of this experience can help in designing touch applications.

    The Impact of Negative Game Reviews and User Comments on Player Experience
    (ACM, 2011) Livingston, I.J.; Nacke, L.E.; Mandryk, R.L.
    Game reviews and player ratings have an effect on the commercial success of games. They are used extensively by game developers to gauge the success of their titles and by potential buyers to make more informed purchase decisions. However, their potential influence on player experience remains uncertain. We investigated how game reviews and user comments influence players' affective states and experiences during game play. We found that both professional reviews and user comments (especially the negative comments) affected experience measured through game ratings, and that this effect was not mediated by changes in players' moods. Our results are important to the game industry because of the meaningful negative effect that user and critic comments can have on individual player experience and the resulting commercial success of a game.
