Academic Oral Presentation allows students to express ideas and present research findings. However, students often face the challenge of integrating verbal, nonverbal and visual elements into the presentation.
Based on a need-finding survey, a design study and an expert interview, we proposed Trinity, a hybrid delivery support system that provides guidance for multichannel delivery on-the-fly.
We conducted a controlled between-subject user study to investigate the usability, effectiveness, interaction, influence, trust and collaboration of Trinity.
