Laval Virtual

My Journey Through Laval Virtual: The Quest for Immersion in the World of Virtual Reality

To give you some context you will find a brief summary about myself at the end of this post.

As an enthusiast of the concept of virtual realities, I was eager to attend Laval Virtual, the premier event showcasing the latest advancements in VR, augmented reality (AR), and mixed reality (MR) in short XR in as someone put it humbly the capital of VR! I couldn’t wait to dive into the world of cutting-edge technology, engaging discussions, and artistic creations. Throughout the event, I found myself constantly questioning: “What truly defines immersive experiences in XR?”
This is my personal journey to and through Laval Virtual as I explored innovative brands, participated in thought-provoking discussions, and found inspiration in the arts, all in the quest for immersion. But before I let you read the text itself I offer you the possibility to immersive yourself in a few 360° photos from various stages of my trip.

You can freely navigate with your mouse within the 360° image, there is even a hotspot you can click on and move on to the next image.

Note: While writing this on Friday 14 April, Laval Virtual is still on-going, but unfortunately I have to catch a train and then plane to make it home still today. Greetings from Paris Charles de Gaulle airport.

Discoveries

During my first day on Wednesday 12 April, I was thrilled to explore the innovative brands and technologies being showcased. As a newish VR enthusiast, I was particularly impressed by Movella‘s Xsense,  found the approach L.A.P.S. is taking interesting and thought Olfy had taken the next logic step in bringing one more of our senses to the XR table, very refreshing. Xsense’s groundbreaking work in motion capture, live avatar performance solutions, and sensory integration expanded, seeing it live, my understanding of what’s possible in VR and AR experiences.
L.A.P.S.’s solutions on the other hand enable real-time facial expression tracking, which allows avatars to mirror the movements and emotions of the performers in real-time. Finally Olfy is a virtual reality system that simulates smells to create a more immersive experience. In their own words: The sense of smell allows virtual reality experiences to be more engaging and immersive. Our goal is to enhance the emotions and effectiveness of virtual experiences by allowing you to experience them 100% (Olfy).

Thought-Provoking Conversations

As I attended the various discussions and keynotes, the Immersive Digital Learning topic stood out as a highlight for me, particularly the engaging panel discussion featuring Anaïs Pierre, Bogdan Constantinescu, Jayesh Pillai, and Thierry Koscielniak. Anaïs passionately emphasised that technology serves as a tool, and we must prioritise learning goals before seeking the appropriate technological solution. The use of tech tools must be purposeful and meaningful.
This is exactly how I feel about the use of technology in general. Content and (in my case usually) learning goals first, otherwise your course or product will not find its full potential.

I listened to Kent Bye’s fast-paced talk on the topic of XR moral dilemmas and ethical considerations. He discussed several crucial concerns that we should all be pondering, including the digital divide in access to XR technology, threats to privacy (e.g., biometric data), apparently there is no legislation on this and similar issues.

Furthermore a new concept I hadn’t heard before: mental privacy which is part of a proposed set of rights called the Neuro rights. Mental privacy refers to the protection of an individual’s thoughts, emotions, and mental processes from unauthorised storing and access, particularly in the context of novel technologies that can potentially monitor or manipulate these aspects of the human experience. This really jump-started my brain and I am still processing all the possible implications and reflecting on the ethical and practical considerations of using XR technologies in education and beyond.

During another panel discussion, I was introduced to the concept of eco-design, which involves reducing the energy footprint of eg. VR headsets. It became clear that as VR technology evolves, we must be aware of and address the energy-intensive nature of these devices to create a more sustainable and ethical future. By incorporating eco-design principles, we can minimise the environmental impact of VR and ensure a more responsible approach to technology.

Finding Inspiration in the Arts

Now of course Recto VRso cannot go unmentioned in this blog post. Recto VRso is a component of Laval Virtual, which this year took place partially at Le Quarante, a cultural center in Laval and L’Espace Mayenne. It showcases innovative uses of XR in the field of art and culture. Attendees can interact with some of the  installations that push the boundaries of what is possible in XR art, providing a platform for networking and inspiration in the field – further fueling my passion for the intersection of technology and creativity.

I’d like to single out one installation called Memory house by artist Jiahe Zhao.
According to the artists own words an my rough translation into English: Numerous items hold cherished memories, ranging from beloved family toys to treasured travel souvenirs. “Memory House” offers a solution for storing these memories in a virtual realm. By using 3D scanning technology, memory objects are brought into the virtual space, and through transformation by AI (artificial intelligence), they are manifested into a one-of-a-kind virtual edifice that is ideal for exploration.

And yet Recto VRso seems to be an exception. Over and over have I noticed that XR related applications are heavily situated in the engineering, training/onboarding and skills learning sectors, very little is to be found in the liberal arts world, sadly. Having an academic background in field of liberal arts myself I was excited to discover the creative applications of XR technology at Laval Virtual. I found inspiration in BavARt, an AR-specialised firm that combines art and technology in a Pokémon Go-style app.

Immersion?

As I left LavalVR, I couldn’t help but reflect on my initial question of what defines immersive experiences in VR. Throughout my journey, I discovered that immersion is not just about cutting-edge technology and realistic visuals. It also involves connecting with our emotions, bridging the gap between the digital and physical worlds, and finding inspiration in the creative fusion of art and technology. The quest for immersion is a never-ending journey, one that continuously ignites my enthusiasm for discovering the boundless opportunities that await in the world of virtual reality.

Final thoughts

This was my first conference I attend on my own, I knew no one at Laval and because I am not really an extrovert, but an observer if you will, I struggle connecting with  strangers. Most attendees were there in larger parties and would therefore communicate and entertain themselves among each other which makes it for outsiders as myself hard to mingle. I am not complaining just stating what I noticed.
Yet at the hotel I couldn’t help but be involved in socialising with the French during breakfast. As people were arriving to the breakfast they were greeting everybody and they were greeted by the ones already there. People would ask each where they’re from and what they’d do and so forth. There was active communication throughout  breakfast. I loved it

And finally, note that the venues for the Laval Virtual are kilometers away from each other and not just quelques pas (a few steps) as was repeated by officials a few times =)  Nonetheless I took this as an opportunity to walk and boy did I do some walking, a total of 27km on two and a hald days between my hotel and the three venues.

Thank you Laval Virtual et à la prochaine!

Background

I am fairly new to the XR world, in fact it was only last October (2022) that I had a VR headset on for the first time, imagine that! Having studied languages, folkloristics and other liberal arts subjects (at the University of Helsinki (UH)) I have noticed that I have a somewhat different approach to technology than most of my peers. I have been working in several positions at UH over the last, almost two decades including as an International exchange expert and Edtech specialist before joining the Global campus team. As a lifelong learner I started studying university pedagogy last year at UH believing it will give me a strong understanding of educational technology. Furthermore I am the chair of Una Europa’s Educational design and technology cluster. For more coherent  info on me see the Us section.

Case Sustainable Health – a teacher’s view on Global Campus collaboration

Surreal handshake

 

Sustainable Health is a multidisciplinary online course that discusses sustainable development themes in the context of healthcare and life sciences. It serves as the discipline-specific counterpart to the University of Helsinki Sustainability Course (SUST-001). It is currently being piloted in the University of Helsinki, Faculty of Pharmacy, and development is ongoing for its expansion into a massive open online course (MOOC).

The course employs a highly learner-centred approach, giving participants ample freedom in terms of how and when they choose to complete it. The students construct an e-portfolio, where the participants compile reflections on sustainability challenges and solutions. The portfolio may be based on pre-defined assignments or other freely chosen topics that align with the learners’ interests. Mid-course, students exchange peer feedback on their portfolio drafts, and at the end of the course peer assessment is carried out to verify that the portfolios meet the passing requirements of the course. The participants can choose whether they wish to complete the course within one teaching period or over two consecutive periods.

The collaboration with Global Campus begun during the development phase of the first pilot version of Sustainable Health. At the time, large parts of the course content had been prepared and the outlines of course completion mechanics drawn. What we felt was still missing was a unifying concept to tie together the individual topics and tasks of the course in a way that would keep the students motivated throughout the extended periods of self-paced studying. Additionally, we wished to gain expert insight into the execution of the peer feedback and peer assessment workshops. This is where Global Campus stepped in.

I was immediately amazed by the can-do attitude of the whole Global Campus team. In the beginning of the collaboration, I was asked to compile a wish list of features and enhancements for the course that the team could help me with, which felt like a strange position for someone whose work typically involves catering to the wishes of other teachers. Not having a clear sense of the full range of possibilities, I was initially hesitant with my hopes, but it soon became evident that the options would be only limited by my own imagination. For example, what started as an idea for using text-to-speech snippets to introduce the course content was transformed by Global Campus into a full sci-fi narrative, delivered in a post-apocalyptic virtual reality environment by an avatar from the future. Such a mind-blowing reference point has taught me not to hold back my scope based on what I expect to be within the realms of possibility.

Furthermore, I received valuable advice on how to organize the exchange of peer feedback among the course participants and got excellent insight on how to formulate the feedback instructions and questions in a way that would make the assessment process motivating and useful to the students.

Despite the creative and uninhibited atmosphere, working with Global Campus was very organised. With Sasa Tkalcan’s excellent coordination and comprehensive documentation on the shared project whiteboard, the goals were set very clearly, and progress towards them was regularly monitored. I really liked this approach and hope to apply it in other collaborations later on. This was also my first time working with some of the project management tools involved, like Kanban, so I also acquired new tracking methods for my projects.

During the development phase, Sustainable Health was one of two concomitant Global Campus pilots. Despite the completely different disciplines and course topics of the pilots, we had several meetings between both developers and the whole Global Campus team and ended up having an extremely fruitful collaboration based on the shared goal of creating quality e-learning. Some unique ideas that arose in our joint discussions ended up as crucial parts of Sustainable Health (and vice versa, I hope), highlighting the impact of the interdisciplinary brainstorming. I have no doubt that we will keep in touch and continue sharing ideas and good practices with the developers of the sibling pilot also after the finalisation of both projects.

The biggest challenge I faced during the collaboration was the allocation of my personal resources between developing the e-learning mechanics of the course and producing learning materials. The latter task was initially hoped to be shared within a larger group of subject matter experts, but the dynamic nature of the working group and the limited time resources of the experts proved challenging for co-creation. Eventually, I took on a large portion of the scientific content creation to ensure that the course would be ready for piloting on schedule, which limited my availability for the conceptualisation of experimental e-learning elements. On the bright side, the content is now in place with the pilot, allowing the future development of the course to focus purely on educational technology innovation and making the course as fun, engaging, and inspiring as possible. Conversations with the Global Campus team and other pilot developers revealed that the issue may in fact be more general, as it may often be challenging for subject matter experts to find the time to produce certain types of content, such as video lectures. However, it was also highlighted that AI-assisted technologies, such as text-to-speech and digital avatar tools, could significantly reduce this barrier and make it easier to co-develop learning materials in the future.

Overall, working with Global Campus has been a great experience that has really expanded my perspective on what is achievable when open-minded enthusiasm meets with the latest technology. In addition, the collaboration between the two parallel course pilots served as a great example of how multidisciplinary teamwork and idea exchange can greatly enhance course development projects when facilitated by a great team. I feel that by sharing knowledge and best practices between the projects, we established a framework that could be easily adopted to guide future course development initiatives.

AI-Powered Course Material Production

Introduction: The Global Campus of the University of Helsinki is committed to exploring innovative methods for enhancing educational experiences. As part of this ongoing mission, our recent “AI methods in course material production” presentation at the university’s Learning Adventure showcased the potential of cutting-edge AI technologies in creating engaging and dynamic course materials. While our primary audience was the university community, we believe these insights hold value for all EdTech enthusiasts.

In this blog post, we’ll share key takeaways from our presentation, which encompassed five sections: Text, Images, Audio, Video, and Q&A.

  1. Text: Harnessing ChatGPT’s Potential. Kicking off our presentation, we introduced ChatGPT, an AI language model developed by OpenAI. By delving into the concept of prompting, we unveiled various techniques, including Chain of Thought (CoT) methods. Highlighting the effectiveness of role prompting, we showcased ChatGPT’s self-criticism and self-evaluation features as a means to generate meaningful responses.
  2. Images: Visualising Ideas with Midjourney. Transitioning to text-to-image (T2I) generation, we presented Midjourney as an exemplary case. Demonstrating seamless integration between Discord and Midjourney, we revealed the process of creating images through prompting in Discord. For a deeper understanding of the Midjourney case, we invite you to read our earlier blog post here.
    It’s worth noting that in addition to Midjourney, there are several other AI-based applications that allow for the creation of images through text. One notable example is DALL-E, which uses a transformer-based neural network to generate images from textual descriptions. And let’s not forget about StableDiffsusion, a new AI-based technology that allows for the generation of high-quality, realistic images by leveraging the power of diffusion models. With so many exciting applications available, the possibilities for creating images through text are truly endless.
  3. Audio: Bringing Text to Life through AI. Our third segment explored the realm of text-to-audio conversion. We shed light on AI tools and techniques capable of generating lifelike speech from written text, making course materials more engaging and accessible to auditory learners.
  4. Video: Creating Dynamic Learning Experiences with AI. In the penultimate section, we investigated AI’s potential in video production. Discussing the role of artificial intelligence in crafting compelling and informative videos, we emphasised the importance of delivering course content in a visually engaging manner. In addition to Synthesia and Colossyan, there are several other noteworthy applications that are worth exploring. One such application is D-ID, which is a deep learning-based technology that allows for the anonymisation and replacing of faces with natural or fantastical looking options in videos using AI-generated imagery. With the increasing demand for video content in today’s digital landscape, these and other AI-based text-to-video applications offer opportunities for teachers and students to create high-quality videos quickly and easily.
  5. Q&A: Encouraging Audience Interaction. To wrap up our presentation, we engaged the audience in group discussions, addressing questions and concerns stemming from the event. This interactive session fostered a deeper understanding of AI’s role in education and promoted collaboration within our university community. Participants were interested in for example if it was possible to produce materials in Finnish language with these new tools and yes, usually that is also possible.

Conclusion: Embracing AI-powered tools like ChatGPT, Midjourney, and other text-to-audio and video production solutions is revolutionising the way we develop and deliver course materials. By adopting these innovations, we can create more engaging, accessible, and dynamic learning experiences for students across the globe.

AI is not taking away your job, it’s the person that adopts AI that is taking away your job!
