Just canceled my #chi2022 physical conference attendance and switched to online. Would have loved to go but unfortunately the Covid situation, especially traveling from Germany, is not quite under control yet.

Happy 40th Birthday, Sinclair #ZXSpectrum! Like for a whole generation, this little black computer got me into computer science — and its elegant design and user-friendly manual first nudged me towards a career in human-computer interaction: hci.rwth-aachen.de/spectrum #spectrum40

Just deleted my @WhatsApp account, after exporting important chats and media. The privacy concerns had just gotten too much. Now happily chatting with my extended family on @ThreemaApp, where I can choose again who can contact me. Nice! #leavewhatsapp

Our #chi2021 paper "From Detectables to Inspectables: Understanding Qualitative Analysis of Audiovisual Data“ received an Honorable Mention Award! hci.rwth-aachen.de/video-ana…

After a year of global home office, @MicrosoftTeams on #macOS is still spectacularly bad at supporting Keynote presentations. If you cannot use @zoom_us, here is how to at least get back things like seeing your presenter notes and the other participants: hci.rwth-aachen.de/teams
6 hours before the #CHI2021 paper deadline, our admin shows me this report from our lab's central research file server. Talk about scary GIFs.

To polish our #CHI2021 papers, I record my screen highlighting things to fix in the PDF, and record my voice comments, all in QuickTime Player. Students find those points via the audio waveform in ChronoViz or iMovie. Makes me very productive, and students learn from my comments!

Largely unnoticed, last year @Apple began the most radical change to iOS & macOS development since its Mac OS X 20 years ago. #SwiftUI's declarative paradigm massively lowers the bar to writing apps, but experienced developers need to rewire their brain. developer.apple.com/xcode/sw…

See our current @fablab_aachen up close in a half-hour video tour I gave last night. New high-end 3D printers thanks to support from the @RWTH #Aachen Excellence Startup Center NRW. Thanks to @rene_bohne for inviting me to his Maker livestream! youtu.be/FHfjtSVKi-Y (in German)
Due to #Corona, we flipped our undergraduate HCI lab from building stuff in our @fablab_aachen to coding plugins for @Ultimaker's Cura 3D printing software. The results are amazing. It's fun working at a university like @RWTH with such bright students! hci.rwth-aachen.de/m3

The flat design started by Windows Metro and iOS 7 clearly impacted usability ("is this thing interactive?!)". With @macosbigsur at #WWDC20, that direction finally seems to change back to making sensible use of realistic visuals and depth cues. A big moment for visual design.
It took me a week to gather my thoughts but I have been waiting 7 years to write this.

On the philosophical change in the role of visual design and why I think we're on the cusp of a new era. #WWDC20
How should we interact with AI systems? They aren't tools, humans, or pets. We call them Otherware. Join our first Otherware workshop at NordiCHI this October. Deadline Sep 1. hci.ac/otherware
#FabLab's and #Makers, start #3Dprinting hands-free door handles from Materialise's free designs for your home and workplace today to help stop spreading #coronavirus: materialise.com/en/hands-fre…
First results of @fablab_aachen joining the global open-source fabrication initiative for #3Dprinting simple medical supplies from visors for doctors to underarm door handles to avoid spreading the #coronavirus. See hci.ac/fightcorona. #FabLab
Our @fablab_aachen gets ready to help the European Commision with #3Dprinting emergency supplies for the #coronavirus epidemic. Join the cause! it-sicherheitscluster.de/dri… #FabLab

My PhD student Christian Corsten did a great job defending his thesis "Use the Force: How Force Touch Improves Input on Handheld Touchscreens" today. An excellent introduction to the area, based on several CHI papers. Congratulations! @sig_chi #chi2020 hci.rwth-aachen.de/corsten

Will our grandkids still learn to write? I'm discussing the future of learning with @RangaYogeshwar and others at the final stop of the #ErfahrbaresLernen learning technologies road show in Aachen this afternoon, which we are hosting for the @BMBF_Bund. vdivde-it.de/veranstaltung/i…🎓 – at Aachen, Germany
