In modern text-based communication and online meetings, graphical expressions such as emojis and visual effects are widely used as effective means of conveying emotions. In this study, we aim to enhance face-to-face communication by developing a novel display system that projects aerial images in mid-air around a person’s face. Previous research has explored communication-support interfaces using displays on tabletops or partitions; however, these methods suffer from optical challenges such as projector light entering directly into the eyes and reduced transparency of acrylic panels. In addition, head-mounted systems like HMDs not only obscure facial expressions but also pose difficulties for prolonged use due to their weight. Therefore, we have developed a chair-based aerial display that employs an optical system mounted on the chair’s backrest to project speech bubbles and manpu as if emanating from the user’s face, thereby enabling natural face-to-face communication without the need for heavy wearable equipment. To verify the effectiveness of our system, we implemented applications based on two use casesenhancing emotional expression in face-to-face communication and supporting communication for individuals with hearing impairmentsand conducted a preliminary qualitative evaluation through feedback collection. The results suggest that the system has the potential to amplify users’ emotions, facilitate conversation, and naturally direct their gaze toward the face.
