Hi, my name is Lucas.

I am bi-national Ph.D. student at the Colorado State University in Fort Collins and the HCI Group at University of Würzburg researching notifications in Augmented Reality. I have a Master's and Bachelor's degree in Human-Computer-Interaction.

VRST 2023 in Christchurch New Zealand: Notification Interaction in Augmented Reality

A big part of my PhD happened during the pandemic, so I was more than thrilled to present my paper for the first time in front of a live audience at ACM VRST 23 in Christchurch New Zealand. The people there were so incredibly welcoming and the country was one of the most beautiful places I have ever gotten the pleasure to be in. The conference was an amazing experience, and I met so many great researchers. The paper I presented was about how to interact with notifications in AR.

Poster at ISMAR 22 in Singapore

Taking place in Singapore in 2022, I was lucky to be able to present my poster anda demo about notification placement in AR at the ISMAR conference. The conference was very interesting and Singapore was an incredible country, that I plan to go back to as soon as I can. This work was expanded upon and published at ACM SUI 2023 as a full paper, but the conference was online-only.

Patient Monitoring in AR

Human error accounts for the majority of patient safety issues in intensive health care. I investigated using Augmented Reality in anesthetic inductions to aid anesthesiologists in surgery and increase their user experience, implicitly increasing patient safety. For that I implemented an AR patient monitoring system and evaluated it with 30 senior anesthesiologists in a simulation study at the University Clinic of Würzburg. This was my master's thesis and was published as a poster in VRST 2021. While I did not see a benefit using the monitoring, it did lead to my eventual PhD topic, AR notifications! Anesthesiologists expressed their wish to receive alarms and notifications on the headset, so they can be up to date without resorting to other means such as using a cordless phone or smartphone.

Text-entry Methods for Virtual Reality

In my bachelors' thesis I implemented several 3D text input methods for virtual reality applications and conducted a user study comparing the different methods regarding speed, error rate and usability.
