To demonstrate this approach, we designed an immersive presentation centered on the exploration of the solar system, where predetermined regions function as presentation slides. The user, acting as the presenter, exhibits content by scaling and moving the VE over the course of the tour, allowing for both large-scale context and close inspection of details while maintaining clear instructional flow. Presenters are additionally able to move and scale the region within predefined limits for spontaneous, additional instruction. The guided tour provides narrative segments comparable to a presentation slide while allowing attendees to explore current and previously visited regions. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"336\" src=\"https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2026\/02\/image-1024x336.png\" alt=\"\" class=\"wp-image-3545\" srcset=\"https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2026\/02\/image-1024x336.png 1024w, https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2026\/02\/image-300x98.png 300w, https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2026\/02\/image-768x252.png 768w, https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2026\/02\/image.png 1199w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Regions with stand-in attendees at different, predefined scales including: (A) Solar system scale (B) Earth Scale.

She holds a Ph.D. in Computational Modeling from the National Laboratory of Scientific Computing in Brazil. Her research lies at the intersection of human-computer interaction and artificial intelligence. Her interests center on context-aware and intelligent Extended Reality (iXR) systems, particularly how immersive interfaces can sense contextual information about the user, task, and environment, reason over it, and adapt accordingly. This adaptability is essential for XR to be practical and effective in everyday life. The broader impact of her work is to create XR solutions that enhance productivity, communication, well-being, and accessibility across a wide range of applications, from education and medicine to everyday tasks.<\/span>"},{"term_id":562,"user_id":0,"is_guest":1,"slug":"nakul-kumar","display_name":"Nakul Kumar","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","author_category":"","user_url":"","last_name":"","first_name":"","job_title":"","description":""},{"term_id":563,"user_id":0,"is_guest":1,"slug":"jasmine-walker","display_name":"Jasmine Walker","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","author_category":"","user_url":"","last_name":"","first_name":"","job_title":"","description":""},{"term_id":564,"user_id":0,"is_guest":1,"slug":"hamid-tarashiyoun","display_name":"Hamid Tarashiyoun","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","author_category":"","user_url":"","last_name":"","first_name":"","job_title":"","description":""},{"term_id":391,"user_id":331,"is_guest":0,"slug":"dbowman","display_name":"Doug Bowman","avatar_url":{"url":"https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2021\/01\/professional_photo2_2019-cropped-square-smaller-scaled.jpg","url2x":"https:\/\/wordpress.cs.vt.edu\/3digroup\/wp-content\/uploads\/sites\/141\/2021\/01\/professional_photo2_2019-cropped-square-smaller-scaled.jpg"},"author_category":"1","user_url":"","last_name":"Bowman","first_name":"Doug","job_title":"","description":"Doug A.
