Multi-touch tabletop systems promise to enhance collaboration in
multi-display (MDE) environments. However, little is known about the effects
of combining shared multi-touch tabletops with multi-touch tablet computers
(tablets) as the collaborators' personal displays. In this paper we present the
implementation of a MDE with multi-touch input on both shared and personal
displays and its evaluation regarding task performance, user preferences and
collaboration strategies compared to a standard multi-touch tabletop setting.
Eight participant pairs had to solve a collaborative sorting task using three
different transfer techniques. Based on an analysis of video recordings, log files
and user feedback we identified task solving and collaboration strategies. The
use of tablets enabled participants to follow diverse strategies and participants
preferred the collaboration using tablets, while overall task performance and the
amount of close collaboration were higher without the tablets.
