A Fitt of distraction
Denis Lalanne, Agnes Lisowska Masson · 2011
This paper presents the results of an experiment aimed at measuring the impact of the number of distracters and of co-located users on individual pointing efficiency. The experiment, performed with 20 users, is a variation of a Fitt's Law test in which we incrementally augmented the number of distracters on the screen and the number of co-located users. The results show that the number of distracters clearly influences users' pointing performance. Further, it shows that users are more efficient at pointing items when they share the display with co-located users than when they are alone.
