These are notes from listening to Immersive Analytics with Tim Dwyer, a podcast interview on Data Stories 2019. These are free-form and I make no guarantee of correct grammar.

He started studying this field around 2001

My take: We’re still, in 2022, kinda in the same place as described here... imagining AR as a way to look at a physical object and seeing or hearing information

An AR headset can talk to the output of an IoT connected machine

• Get that info into your headset

Aim to use natural gestures

They simulate Augmented Reality environments in virtual reality. The VR devices have a wider field of view. The controllers you get with VR devices track very accurately.

They create screens hanging in the virtual space - they're interested in the combination of the screens.

That allows us to imagine the future more than working in the current limitations of the AR technology.

• The Human Computer Interaction
• Filtering in data visualization

What does a ‘slider’ look like in VR??? The way this was solved on the desktop needs to be rethought

Today is like the 1980's

• people explored a lot of kinds of computer mouse until they found what actualyl works
• many people don't know how much university work went into that kind of research

There are a lot of challenges to solve

"Flow-maps"

Yalang Yang (check spelling ) “Maps of movements of people, or trader, overlaid on a cartographic map.” This has been discussed in the visualization community for a long time. In the 19th century there More recently they were generated automatically onto 2d maps We show flows on the globe. You have the classic problem

side note from Bill...wow…I'm just remembering I’ve had this dream since I was a young kid - seeing a slowly spinning globe in front of you that you can zoom in and out of, and see very detailed, animated information as you move in.

In 3D, you can map 3 dimensions to x,y,z

• Perspective distortion
• Occlusion

Using haptics

• you can "feel" holes in the data
• or feel the data as a wall
• the takeaway from that paper (note: find the paper)both of those haptic interactions improve your ability to see inside dense clouds of data

• Windows mixed reality framework

Immersive Analytics Toolkit Maxime (Maxine?) IATK

• github

InfoVis from 2018 also presented other toolkits.

Host: 'we have go through a time when people try crazy things!'

collaborative data visualization

VR: data instantiated in the world around and walk around it
