Select InfraVis Projects
These projects are examples of the added value that InfraVis aims to provide researchers who use the infrastructure.
The intermediate data produced by large simulations is typically discarded because it is too large to save. Yet, we can get a deeper understanding of the data by analyzing and visualizing it during the simulation, before it is discarded. In this project, the researchers visualize the behavior of wind around airplane wings while the simulation is running on a supercomputer. A deeper insight into wind behavior will aid engineers in designing more efficient aircraft.

In the future, a digital copy of your own body – a digital twin – may be used to help you understand how to live a healthy life. At Linköping University (LiU), mathematical models are being developed as tools for better health communication. This is the result of collaboration between engineering biologists, psychologists, software developers, behavioral scientists and doctors.
InfraVis helps bring the data to life with Motion Capture animations and realistic 3D models of patients to help communicate medical information in a more personalized way.

In this pilot project, researchers in political science make use of an information visualization dashboard to understand how the contents of social media posts addressing published e-petitions relate to the theoretical model of mobilisation strategies (including information spreading, persuasion, and social support). What are the roles and behavioral patterns of individuals and groups in information diffusion of the petitions and corresponding discussions?
Interactive visualization will assist InfraVis users with:
- Construction of a “big picture” (supported by models and evidence in the data) regarding online activism
- Identification of particular mobilisation patterns (consistent posting on social media, persuasive posts at the beginning or end of the campaign, etc.)
- Guidelines for online activism

We develop interactive spatio-temporal views of arctic areas affected by climate change, where the researchers can register their data and compare the material to trace the changes of the landscape over time.
The visualisation will allow researchers and public alike to follow the human presence through documentation of the Magdalene-fjord (Svalbard) over 400 years, while also seeing the effects of climate change on this environment.

We develop an interactive map where the impact of noise is dynamically visualised through heatmaps over the course of a day as a synthesis of pedestrian traffic and noise level at a certain place and time.
The visualisation can lead to a discussion about the regulations for sound environments, and to the initiation of new research questions about health effects.

The project aims at designing an infrastructure that supports VR applications in the cloud using 5G/6G.
- Reduced requirements for expensive and immobile hardware setups to deliver access to complex applications such as CellexalVR.
- Visualization and manipulation of large datasets through VR.

How have people and climate changeaffected Earth’s pastbiodiversity?
This project aim to demonstrate the availability of a long-term record of biodiversity data which could be used to understand the biodiversity implications of the current climate and extinction crisis.
Data within relational database(s):
- Space, global but mainly Europe
- Time, up to one million years, most <16,000 years
- 5086 taxa (~species)
- 22 ecological variables for taxa
- > 8700 soil samples, > 200,000 fossil record entries, > 780,000 occurrences
- Sourced from >1000 publications
- Much variation in quality (temporal accuracy +/- 1 year to ~250,000 years)

Epilepsies are a family of devastating disorders characterized by spontaneous, recurrent seizures. It is one of the most common brain disorders and considered the most burdensome neurologic disorder worldwide.
Available pharmacological treatments are only symptomatic, often with side effects and fail to adequately control seizures in one third of patients.
A 3D-map of the structural changes, underlying the pathological hyperexcitable network leading to seizures, could give us the directions needed to reverse and thus cure epilepsy.

Telling the stories of what it is like to live in urban environments is vital for designing more inclusive and sustainable cities. In this project, researchers combine data about urban environments with information about the lived experience from citizens to tell stories to stakeholders about what life is like within a city. A visualization that offers views of both sensor data and citizen feedback is used in conjunction with a narrator to present a glimpse of modern city life.
