Last week I presented our paper on personalized recommendations in Mixed Reality at @acm-iui.bsky.social 2026 in Limassol, Cyprus. Our system GLAMRec gives players personalized hints on a strategic board game, overlaid directly on the table through a HoloLens 2. #IUI2026 #MixedReality #HCI #AI

A photo of a man giving a presentation at a conference. He stands on a wooden floor holding a microphone, wearing a dark t-shirt and lanyard, in front of a large projector screen. The slide is titled "How do humans learn complex tasks?" and includes a photo of people working with an industrial robotic arm. A roll-up banner beside him reads "IUI 2026, The Annual ACM Conference on Intelligent User Interfaces."

A photo of a metal sculpture on a concrete platform by the sea. The sculpture is a large open steel ring or spiral standing upright, with a polished metallic sphere resting at its base inside the curve. Behind it, calm blue water stretches to the horizon under a clear pale-blue sky, with several cargo ships anchored in the distance. Rocks are visible at the lower left.

A photo of a beach at sunset. Gentle waves break onto wet sand in the foreground, reflecting soft orange and pink light. A low stone breakwater extends into the sea on the right. On the horizon, a distant city skyline of high-rise buildings sits under a gradient sky fading from teal at the top to warm orange near the water. A hilly coastline rises on the far right.

Tomorrow, I will present our paper on learning through personalized recommendations for board games at the @acm-iui.bsky.social conference in Limassol, Cyprus! #Personalization #AI #MixedReality #Learning #BoardGames

An academic poster titled "Personalized Recommendations in Mixed Reality Enhance Explanation Satisfaction and Hedonic User Experience in Board Game Learning" by Sandra Dojcinovic, Jannis Strecker-Bischoff, Simon Mayer, and Kenan Bektaş. The top section contains four images: a view of a board game setup, a diagram illustrating the interaction flow of the MR system GLAMRec, and examples of gameplay with annotated regions for analysis. The main body describes the study, highlighting the investigation of personalized recommendations in Mixed Reality (MR) board games, their impact on user satisfaction, hedonic experience, and trust. The poster is adorned with logos from the University of St.Gallen, ACM Interactions, and IUI 2026 at the bottom.

📢 CfP: International Workshop on Reality Mediation (IWRM 2026) at UbiComp/ISWC 2026 in Shanghai, October 2026. Submissions: 3 July 2026. 🔗 reality-mediation.github.io/2026 #UbiComp #ISWC #XR #HCI As AI, XR, and wearable systems become part of everyday life, they increasingly decide... 1/

The background is a motion blurred photo of a dense crowd of people walking along a city street, overlaid with a dark blue tint. White text reads: International Workshop on Reality Mediation: Personalized, Shared, and Connected Realities. Smaller text below reads: Ubiquitous Computing is increasingly shaping how people perceive, interpret, and discuss the world around them. This one-day workshop asks how such personalized and mediated experiences can remain intelligible, shareable, and societally grounded. A button labeled Co-located with UbiComp/ISWC 2026 sits at the bottom, beside the text Shanghai, China, October 2026 (TBA).

The poster, titled "Creating Personalized Realities That Connect People's Perceptions of Reality", is structured around four research questions (RQ1 to RQ4) covering modelling of ubiquitous personalization systems, data transparency, affordance navigation, and shared perceptions of reality.

From the workshop on "Social Augmentation through XR Technologies", I came away with a much better sense of how other people are approaching Social XR in all its facets. It was very enriching to discuss our paper on a Personalized Society with other researchers in XR and beyond! 3/4

Beach view in Barcelona at sunset. The sun sits low on the right behind a row of palm trees. In the middle distance, the Port Olímpic skyline is visible, including a tall dark tower and the Hotel Arts area. Small waves break on the sand where a few people walk along the shore. Large rocks frame the lower right corner, and two yellow buoys float in the water.

We talked about everything from things close to my own research to topics pretty far from it. It was great to see what other PhD students are working on as part of the Student Mentoring Program, and the feedback from the mentors gave me a few new angles to think about for my own work! 2/4

The poster "Creating Personalized Realities That Connect People's Perceptions of Reality" is partially visible behind them.

➡️ Just got back from five days at #CHI2026 in Barcelona, and I am still sorting through notes and a long list of papers I want to read properly! It was nice to see so many familiar faces again, people I usually only run into at conferences like CHI, and to meet new ones along the way. 1/4

Opening ceremony of CHI 2026 in a darkened auditorium. A large screen displays the message "Welcome to CHI 2026!" with the subtitle "Creating Tomorrow Together" in English, Catalan ("Creant el demà junts") and Spanish ("Creando el mañana juntos"). Below the text, a mosaic style illustration of the Barcelona skyline including the Sagrada Família and the Torre Glòries. A speaker stands on stage at the podium, the audience visible in silhouette in the foreground.

🥽 🌍 How do we design ubiquitous personalization systems that connect people's realities instead of isolating them? Today, I'll discuss this and other questions my PhD tackles at the Student Mentoring Program at #CHI2026! 📄 academia.jrstrecker.de/publication/... #XR #AR #AI #Personalization #HCI

A figure titled 'Connecting Personalized Realities: Challenges and Opportunities in a Personalized Society' by Jannis Strecker-Bischoff, presented at the ACM CHI 2026 Student Mentoring Program Dissertation Research Roundtable, affiliated with the University of St. Gallen Institute of Computer Science. The slide features the RUPS model (published at DIS 2025), a diagram showing how Ubiquitous Personalization (UP) systems work, with interconnected components: UP Recipients (users, bystanders, objects), UP Data Sources (personal user data, content data, situational data), UP Creation (information collection and personalization algorithm), UP Sharing (information collection and sharing algorithm), and UP Delivery (information collection and delivery medium). These components produce a Personalized Reality. Four research questions are listed: RQ1 asks how UP systems can be modelled for responsible design and analysis; RQ2 asks how to give people transparency and agency over their personal data in UP systems; RQ3 asks how Personalized Reality can help humans navigate affordance-rich realities transparently; RQ4 asks what methods can counter isolated perceptions of reality in multi-user scenarios.

🚀 Happy to share that our paper "Ad-Blocked Reality: Evaluating User Perceptions of Content Blocking Concepts Using Extended Reality" has been accepted at #CHI2025! We explored how #XR could be used to block content in the physical world, such as ads, and how users perceive this idea. 👇

The image has a header with the text "Christopher Katins, Jannis Strecker, Jan Hinrichs, Pascal Knierim, Bastian Pfleging, Thomas Kosch. 2025. ACM CHI 2025. Ad-Blocked Reality - Evaluating User Perceptions of Content Blocking Concepts Using Extended Reality" and the university logos of the author's institutions: HU Berlin, University of St.Gallen, Universität Innsbrück, TU Bergakademie Freiberg.
A collage showing six times the same image with an ad for a soft drink on a billboard. In each image the ad is visually adapted by one of these six concepts: blur, desaturate, partial transparency, full transparency, warning (big sign and "Adblock activated" written beneath), Art (a painting of flowers instead of the ad).
Below the images is text with some illustrative icons: Participants preferred... (1) ...appealing and engaging XR ad-block visualizations. (2) ...temporary or permanent blocking depending on the content. (3) ...automatic blocking for sensitive content, manual blocking for other content.
