InfraVis Open Call 2024 - Decision has been made

InfraVis can proudly announce that we received a wide variety of applications to our 2024 open call for in-depth support: 37 high-quality applications from 25 scientific domains, of which 26 have been granted in-depth support.

The demand for InfraVis support has increased to the point that it is now necessary to provide the support over an extended period.

A core mission of InfraVis is to establish collaborative links with other national research infrastructures. Towards this goal, InfraVis has strategically selected projects that will build strong connections to Onsala Space Observatory, the National Genomics Infrastructure, Swedigarch, and Språkbanken.

Our InfraVis node coordinators are now in the process of arranging the first meetings with the users and look forward to start supplying the support.

Visualizing literacy of school children

InfraVis user: Åke Grönlund (ORU), Gustaf Öqvist Seimyr (KI), Olga Viberg (KTH).

InfraVis Application Experts: Liang Zhou (MIUN), Filip Berendt (KTH), Sergey Ignatenko (LiU)

InfraVis node coordinator: Mario Romero Vega (KTH).

Literacy is essential to modern life. Gustaf Öqvist Seimyr, a researcher at Karolinska Institutet (KI) in Stockholm, co-founded the company “Lexplore” to create a platform that uses eye-tracking technology and artificial intelligence to help teachers assess their students’ literacy levels more accurately.

To deliver user-friendly, location-independent visualizations, we developed a web app using D3.js for data visualizations and React for the interface, hosted on GitHub Pages or a web server. Due to confidentiality, users upload their own data locally. Development followed an iterative approach, with features refined based on user feedback to ensure relevance and usability. Each final visualization feature is documented concisely for clarity.

Explore the Nordic Churches and Prayer Houses Project

InfraVis user: Stefan Gelfgren, Andreas Tjomsland.

InfraVis Application Experts: Kajsa Palm (UMU), Maria Podkorytova (UMU)

InfraVis node coordinator: Evelina Liliequist (UMU).

We are excited to share a groundbreaking resource for researchers in religious studies. This project documents and preserves the rich historical heritage of churches and prayer houses across the Nordic region, offering a valuable tool for in-depth study.

What’s Included?

• A unified dataset of churches and prayer houses in Norway and Sweden, with plans to expand to other Nordic countries.
• An interactive web application built with ArcGIS, featuring filters by religious affiliation, time periods, and a dynamic timeline for exploration.
• Guidelines to ensure the dataset’s growth and sustainability for future research.

InfraVis Days in Lund

5-7 November 2024, the Lund University node hosted the bi-annual InfraVis Days, where our vibrant community gathered for three days of insightful discussions, workshops, and networking. With sessions at BMC, the Humanities Lab, Ingvar Kamprad's Design Center, and MAX IV, each venue added a unique dimension to the event. A big thank you to the organizers, participants, and InfraVis users who made these days both enriching and enjoyable. Together, we shared knowledge and built connections that will inspire further collaboration. Looking forward to what we will accomplish together!

Next InfraVis Days will happen spring 2025 at Mid Sweden University.

InfraVis Colloquium on Information Visualization

19th November 2024 Uppsala University arranged a session on Information Visualization, where the renowned professor Professor Alexandru C. Telea, Utrecht University, The Netherlands, was invited to teach.

High-dimensional data is central to a multitude of application fields. At the same time, visually exploring such data is one of the largest challenges in information visualization due to our inherent inability to depict more than three dimensions. In this colloquium, an overview of techniques that have been developed over the years were presented.

The colloquium was structured into two parts. In the first part, classical techniques for visualizing data with a limited number of dimensions were discussed, and in the second part the focus shifted to dimensionality reduction (DR) techniques, which are among the most scalable tools for high-dimensional data visualization. The potential of DR was demonstrated through recent applications in explainable AI.

Visualization Hackathon

A recent two-day hackathon in Lund organized by InfraVis, LINXS, and the QIM Centre brought together researchers from diverse backgrounds to explore how image processing and immersive visualization can revolutionize data analysis from X-ray and neutron tomography. With hands-on tutorials in tools like Python, 3D rendering, Virtual Reality, and Augmented Reality, participants - including many new to image analysis - discovered the power of automated data processing and visualization. The event inspired researchers to move beyond traditional approaches, uncover hidden insights, and foster cross-disciplinary collaboration. Special thanks to all the organizers and Lund University, for creating a welcoming, inspiring environment! 

LINXS Institute of advanced Neutron and X-ray Science has published a longer feature on this event.
