Dierker A, Mertes C, Hermann T, Hanheide M, Sagerer G. Mediated attention with multimodal augmented reality. In: ICMI-MLMI '09: Proceedings of the 2009 international conference on Multimodal interfaces. New York, NY, USA: ACM; 2009: 245-252.We present an AR system to support collaborative tasks by facilitating joint attention. The users are assisted by information about their interaction partner's field of view both visually and acoustically. In a study, the audiovisual improvements are compared with an AR system without these support mechanism by regarding the participants' reaction times and error rates. The participants performed a simple object-choice task we call the gaze game to ensure controlled experimental conditions. Additionally, we asked the subjects to fill in a questionnaire to gain sub jective feedback from them. We could show an improvement for both dependent variables as well as positive feedback for the visual augmentation in the questionnaire
