We envision that in the future, presentations for business, education, and scientific dissemination can invoke 3D spatial content to immersively display and discuss animated 3-dimensional models and spatial data visualizations to large audiences. At the moment, current frameworks have targeted a highly technical user base, prohibiting the widespread curation of immersive presentations. Our ongoing research thrust is to leverage contemporary AR infrastructure to develop an easy-to-use tool for users to curate and spatially present augmented presentations to large audiences.
At Amazon re:MARS 2019, Dr. Tanya Harrison gave a talk titled, “Roving Robots on the Red Planet.” Her talk featured an AR portion in which she interacted with the Curiosity Rover to visually complement the spoken information she conveyed to the audience. Using the Microsoft HoloLens, she tapped on different spatial regions to invoke animations for the rover. Another user used an AR-enabled iPad to stream the interactions to a projector screen. However, any audience member could also use their device to view the AR content in real-time
Our framework allows users to prepare a sequential state of animations. At the time of presentation, presenters can invoke the animations to simultaneously occur on HMDs and mobile devices. For a communication backbone, HoloLucination uses client- server HTTP requests for simplicity and scalability. As shown in the Figure above, every device that connects in session retrieves updates from the web server to switch its animation state index. Presenter and client devices continually poll the server through web requests to receive animation updates.
