PhD Student at the University of St.Gallen, Switzerland. I am researching Personalization, Mixed Reality, Ubiquitous Computing, Eye Tracking, Privacy, Cookies and Coffee. I'm more active on my Fediverse account: https://hci.social/@jannis

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."
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.
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).
Jannis Strecker‑Bischoff standing next to his research poster at CHI 2026. He wears a blue denim jacket over a white t‑shirt and a lanyard marked "ACM Student Member, Full Conference". 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.
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.
Jannis Strecker‑Bischoff, wearing a blue denim jacket, discussing his poster with two attendees at CHI 2026. One listener in the foreground wears a burgundy hijab, the other has long brown hair. The poster "Creating Personalized Realities That Connect People's Perceptions of Reality" is partially visible behind them.
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.
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.
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.
