This paper presents the results of a user study comparing the performance of point-and-select devices for doing selection tasks on a large screen. The performance of a handheld trackball, both in one-handed and two-handed configurations is compared with a standard mouse as a basis of comparison. The results indicate that the two-handed configuration of the trackball is significant[y faster than the one-handed configuration with 13% reduction of the movement time.Finally, the mouse is significantly faster than the two other interfaces by almost a factor of two, although it is not well suited for collaborative environments with large screens because of the need for a working surface that blocks freehand movements.
