We developed face-to-face single display groupware (SDG) that has a novel circular frame and enhanced multiple pointers. The aim of the study is to encourage groups to concentrate on their discussions and thereby improve their cooperative decision-making. We analyzed the information input methods and information that should be shared in a face-to-face SDG by surveying related work. The interface was designed based on this analysis. Three experiments were carried out, with a general parallel input system tested for comparison. The results proved that group task accuracy, participants’ memory, and their subjective evaluation improved when our SDG was used.
