Effect of the Double-Role Function Using Avatars in Remote Presentations on the Ease with which Content is Conveyed

Abstract

We have developed a VR system that supports remote presentations using videoconferencing tools. The system focuses on addressing communication issues caused by the increasing trend of teleworking in recent years. The developed system includes a unique function that allows a single presenter to play double roles simultaneously using avatars, aiming to make remote presentations more easily understandable. In this paper, we evaluated the effects of the double-role function on memorability and the impression of the presentation content using a quiz and questionnaire. The results of the experiment involving 26 participants showed a significant increase in the percentage of correct answers to the quiz when the double-role function was enabled. Additionally, we observed significant difference or trend in other aspects when employing this feature, including the perceived ease of the quiz’s difficulty, heightened confidence in the quiz, and increased overall satisfaction with its presentation.
