Collaboration with DiamondTouch

Abstract

We study the performance of collaborative spatial/visual tasks under different input configurations. The configurations used are a traditional mouse-monitor, a shared-monitor with multiple-mice, and a multi-user input device (DiamondTouch). Our experiments indicate that there is a significant variation in performance for the different configurations with pairs of users, while there is no such variation with individual users. The traditional configuration is not well-suited for collaborative tasks, and even after augmenting it to a shared monitor with multiple-mice it is still significantly inferior to the multi-user input device. © IFIP International Federation for Information Processing 2005.
