MAGIC-Pointing on Large High-Resolution Displays

Abstract

Display space in offices constantly increased in the last decades. We believe that this trend will continue and ultimately result in the use of wall-sized displays in the future office. One of the most challenging tasks while interacting with large high-resolution displays is target acquisition. The most important challenges reported in previous work are the long distances that need to be traveled with the pointer while still enabling precise selection as well as seeking for the pointer on the large display. In this paper, we investigate if MAGIC-Pointing, controlling the pointer through eye gaze, can help overcome both challenges. We implemented MAGIC-Pointing for a 2.85m x 1.13m large display. Using this system we conducted a target selection study. The results show that using MAGIC-Pointing for selecting targets on wall-sized displays decreases the task completion time significantly and it also decreases the users' task load. We therefore argue that MAGIC-Pointing can help to make interaction with wall-sized displays usable.
