This paper discusses group decision making from a visual-interactive perspective. The novelty of our approach is that its major focus is on developing a collection of visual-interactive elements for group decision-making. Our research departs from a collection of representative meeting scenarios to identify common decision-making elements and behavior similarities; and to elaborate a collection of feature sets realizing those common elements and behavior into visual-interactive artifacts. The paper also describes a handled application demonstrating the proposed feature sets. This application has been extensively used to support a wide range of meetings. An important contribution of this work is that the principle behind its approach to decision-making relies almost exclusively on gestures over visual elements.
