1. Introduction
The 2021 HCI-SI conference is the sixth installment of the Human-Computer Interaction Slovenia
(HCI SI) conference series and was held at the University of Primorska in Koper, Slovenia on
November 8, 2021. The goal of the conference was to provide a meetup for Human-Computer
Interaction researchers in Slovenia and in surrounding countries to be able to present their
work, exchange ideas and discuss collaborations. The conference was held in person with
two presentations done online. In total there were 24 attendees. The last keynote was done
in conjunction with the weekly Monday Computer Science Seminar series at the Faculty of
Mathematics, Natural Sciences and Information Technologies, which saw a larger audience.
2. Content
The conference opened with the first keynote speaker, Gregor Geršak from the University of
Ljubljana who presented the talk Gadgets in psychophysiology.
It was followed by a session of four presentations:
• Elham Motamedi and Marko Tkalčič – Prediction of Eudaimonic and Hedonic Movie
Characteristics From Subtitles
• Mateja Jovanović, Vida Groznik and Marko Tkalčič – Predicting the Gullibility of Users
from their Online Behaviour

3. Keynote Spreakers Biographies
Gregor Geršak received the PhD degree from the Faculty of Electrical Engineering, University of
Ljubljana. His research interests include the theory of measurements, precision measurement of
magnetic flux density, and pressure and thermometry. His focus is on metrology of biomedical
instrumentation with emphasis on devices for non-invasive blood pressure measurement and
psychophysiological measurements.
Peter Knees is an Associate Professor at the Vienna University of Technology, Faculty of In-
formatics. He is an active member of the Music Information Retrieval research community,
reaching out to the related fields of multimedia and text information retrieval, recommender
systems, and the digital arts. His research activities centre on music search engines and inter-
faces as well as music recommender systems, and more recently, on smart(er) tools for music
creation. He co-authored the book “Music Similarity and Retrieval: An Introduction” and is a
contributor to the Digital Humanism initiative.
