V 2.4 of reVISit – our online user study platform – is out, and it’s all about speed and stability. There are some new features, including the ability to specify a condition via URL parameters, but the focus was fixing bugs and making sure that your studies run smoothly!

You can read about the release on the blog, or just give it a try!

He timed his arrival in Austria well: his first work-day was spent at IEEE VIS in Vienna. Very glad to have you on board! 🎉 Check out his website to learn about his work: abhsarma.github.io

We created educational tactile versions of UpSet plots, clustered heatmaps, violin plots, and faceted line charts. In interviews, BLV participants said these models helped them build stronger mental models than textual explanations alone.

Can 3D-printed tactile charts help blind and low-vision users understand complex visualizations? Yes, and they are a preferred learning method.

Read Tingying's blog post to see how it works and what we learned: https://www.visdesignlab.net/blog/2025/08/08/tactile-charts/

I’ll be joining the Institute of Human-Centred Computing – https://hcc.tugraz.at/ – and look forward to new collaborations with the fantastic team there. I’ll also stay closely connected to Utah, continuing my work with the amazing team at the SCI Institute and the Kahlert School of Computing.

After an incredible decade at the University of Utah, I’m happy to share that I’ll be returning to my alma mater, TU Graz, this fall as a Professor of Human-Computer Interaction.

I’ll be hiring a PhD student and a PostDoc in Graz—if you're interested in HCI and visualization get in touch!
