A large display-based approach supporting natural user interaction in virtual reality environment

Interactive large-scale displays have significant potential for information visualization and collaborative interactions, particularly in educational and technological demonstrations. In these scenarios, usually a presenter communicates with spectators while allowing them to engage in various tasks. We propose a lightweight display interaction solution that enables multiple user interactions and facilitates natural interactions with objects in virtual environments, such as navigation and basic actions. A study involving 20 volunteers was conducted to assess the system performance and accessibility through object manipulation tasks such as selecting, moving, rotating, and zooming in a virtual environment. The results were compared to those obtained with a head-mounted display. The study found that (1) there was no significant difference in task execution time or precision and (2) the new method was more convenient, intuitive, and preferred by users.
