Visual designers have long viewed this medium for science communication as an opportunity to engage audiences in new pathways for learning, and to help students develop job skills relevant in tomorrow’s knowledge economy.
TRIUMF’s Science Week ’22 provided the laboratory’s Communications team an opportunity to join forces with event organizers and students an ideal venue to pilot a novel and innovative student poster session experience that leaned into the lab’s 20-year long-view strategies with near-term benefits.
Scientific posters have become a rite of passage for students, from primary school science fairs to PhD-level conferences, in the same way a presentation or talk is – the only way to share unpublished data or discuss new ideas in a research or academic setting – nearly everyone in STEM and beyond has been required to create one.
The ‘Big Idea’ began as a cloud-connected Virtual Reality (VR) poster session. The requirements were a suitably powerful workstation, VR headset, and the ability to connect to an established presentation server using a collaborative VR platform. While passive participation may have been arranged with large displays in a single location, this dream was global, allowing students anywhere the opportunity to participate. Similar scenarios have become de rigueur for automotive and industrial design in the remote work era.
To scale the idea, the working group began tapping TRIUMF’s partner network to identify local hubs and nodes capable of supporting student presenters with sufficient computing power and VR support. This sharp technical and administrative curve also presented a considerable barrier to entry for student presenters who’d need a greater knowledge of modeling and rendering tools and techniques to stand up their presentations.
The group focused on plotting one small step – an incremental innovation – and pivoted their intentions towards an Augmented Reality (AR) student poster session. AR acts as a supplement to the existing poster, expanding on the printed paradigm with no requirement for attendees to engage in the technology.
“I got really inspired and excited to be guided through this next-level poster session.”
One challenge the group had to overcome was that the production and presentation method had to strike a balance between advancing the Big Idea and maintaining an accessible event. It had to account for all skill levels, and given the students’ academic and work schedules, a relatively manageable amount of effort.
To establish which tools, technology, and approaches would be used to guide the students the group developed an AR prototype to highlight TRIUMF’s contributions to and role in the international ATLAS collaboration. This blended 2D infographics with existing 3D models made available by CERN as a proof of concept to present how both mediums supported various AR interactions.
With a robust example and documented workflow, the first cohort of pioneering students embarked on a 5-week sprint to ideate, implement, and augment their scientific concept for the first-time using AR technology.
The work began by conceptualizing how the poster content could be explored in 3D space and how any available models or schematics could be tailored in interesting ways allowing students to develop new skills in 3D modeling and augmented scene composition.
The poster and AR projects were loosely coupled since they required completion in sequence. Print deadlines came first, while the AR demos were hosted in the cloud, allowing students to test and iterate right up to the moment of the event. Each poster was embellished with a pre-established QR code linking the two experiences.
The event was a smash success – nine student teams and individuals delivered a suite of AR demonstrations with photos, drawings, and movies using creative blends of fully conceived user interfaces, animated characters, and 3D models with exploded–views.
The event design allowed for the students to use a traditional poster presentation while showcasing their AR demos through a mobile tablet. The integration of QR codes allowed anyone with a compatible smart phone to freely explore the AR demos without waiting in line or struggling to listen in. This setup allowed for remote participants to easily attend as well; with the physical poster printed and AR demos in the cloud, these presenters appeared on a second screen connected by video to discuss their work with attendees.
The addition of a VR showcase provided an additional benefit for spotlighting these professionals for their contributions to world-class research in head-mounted displays interacting with one of-a-kind components developed for the lab’s Advanced Rare Isotope Laboratory (ARIEL).
"Participating in the AR poster session was a great learning experience. I enjoyed using new communication tools, and as a remote participant, I had to think a little harder to make the AR experience more immersive, interactive, and self-guided from the audience perspective. The key takeaway for me was to focus on the ease of access for the audience, regardless of the medium."
Both AR and VR allow researchers, engineers, students, and even career educators to present results, visualize data, and discuss unique ideas in ways not possible before. The experience becomes more inclusive, as all senses are deployed at the same time. For visual learners, starting in primary school, these mediums might make more complicated concepts in math, biology, and technology easier to approach and understand.
One key example – inspired by the Science Week AR poster session – is the development of a VR application by a local Grade 7 student for a science project at University Hill Elementary School located near to TRIUMF. The student used the same tools employed for Science Week to imagine what a Mars base camp might look like. All modeling was completed in TinkerCAD, software free for schools to use. The 3D models were imported into Sketchfab for Oculus VR to shape the 360-degree environment by creating walk paths and crafting views from space – a truly mind-blowing experience for early STEM + Art (STEAM) enthusiasts. This fundamentally changed how the students engaged their senses in learning – through sight, hearing, and touch – and highlighted new concepts not easily translated through paper or on screens.
Being able to share their interpretation of life on Mars while inside a classroom setting is truly becoming the next generation of immersive learning.
