The MAGIC Touch: Combining MAGIC-Pointing with a Touch-Sensitive Mouse
Proceedings of the 12th IFIP TC13 International Conference on Human-Computer Interaction, INTERACT 2009, Uppsala, Sweden, August 24-28, 2009, ISBN 978-3-642-03657-6. (bib)

In this paper, we show how to use the combination of eye-gaze and a touch-sensitive mouse to ease pointing tasks in graphical user interfaces. A touch of the mouse positions the mouse pointer at the current gaze position of the user. Thus, the pointer is always at the position where the user expects it on the screen. This approach changes the user experience in tasks that include frequent switching between keyboard and mouse input (e.g. working with spreadsheets). In a user study, we compared the touch-sensitive mouse with a traditional mouse and observed speed improvements for pointing tasks on complex backgrounds. For pointing task on plain backgrounds, performances with both devices were similar, but users perceived the gaze-sensitive interaction of the touch-sensitive mouse as being faster and more convenient. Our results show that using a touch-sensitive mouse that positions the pointer on the users gaze position reduces the need for mouse movements in pointing tasks enormously.
