    PowerPoint is a dominant communication tool in business and education. It allows for creating professional-looking presentations easily, but without understanding its constraining qualities it can be used inappropriately. Therefore we conducted a systematic literature review structuring the literature on PowerPoint in three chronological phases (Early Criticism, Heated Debate, and Scientific Take-Off) and identifying 18 constraining qualities classified into three categories: cognitive, emotional, and social. This article provides implications for educators' and practitioners' use (and nonuse) of PowerPoint through synthesis and description of such constraining qualities. Directions for future research are developed by identifying theoretical gaps in literature on PowerPoint.

    As discussions move online, we need means that compensate for what we take for granted in face-to-face meetings: voice modulation, mimics, or gestures. There are three functions of these ‘metadiscoursive' expressions: 1) to navigate conversations and to direct the attention of our interlocutors, deciding what to discuss, reviewing what has been said, or how things are framed 2) to signal attitudes such as agreement or disagreement, or the level of certainty or commitment and 3) to annotate (visual) content with comments. These functions are crucial for the quality of discussions and can benefit from information visualization. To do this, we propose a classification of navigational moves and attitudes and their visual representation in form of "Navicons" and "Atticons". These icons help to improve the quality of online or face to face discussions, to plan conversations in advance, or to analyze past discussions. An example and outlook conclude the paper.
