Talk of Prof. Vivien Petras: ‘Searching Cultural Heritage – Heterogeneity as a Challenge and as a Key’ on January 20, 2017

On Friday, January 20, Prof. Vivien Petras from the Information Science Research Community will present latest research about searching in cultural heritage information systems:

Searching Cultural Heritage – Heterogeneity as a Challenge and as a Key

Speaker Prof. Vivien Petras, PhD
Institution Research Group Information Retrieval at the Berlin School of Library and Information Science at the Humboldt-Universität zu Berlin
Date January 20, 2017
Timeframe 2pm – 3pm
Location Z 1003

Every domain presents different challenges for search environments. Heterogeneity in many variations (content types, data quality, multilinguality, audiences) is the unifying challenge of all cultural heritage information systems. This talk will discuss Europeana, the European digital library, museum and archive, as a case study for cultural heritage portals and introduce domain-specific interaction scenarios for this environment, which differ from general web search. It will present challenges we have identified in integrating cultural heritage resources in a search environment and discuss implementation solutions such as data enrichment, multilingual non-textual information access components that promise improvements but may also introduce other pitfalls.

Talk of Prof. Dr. Jörn Hurtienne: ‘Intuitive Use, Image-Schematic Metaphors and Quantifying Interaction’ on December 19, 2016

We are happy to invite you to the following talk, which is part of the SFB-TRR 161 lecture series:

Intuitive Use, Image-Schematic Metaphors and Quantifying Interaction

Speaker Prof. Dr. Jörn Hurtienne
Institution Psychological Ergonomics at the institute Mensch-Computer-Medien [Human-Computer-Media] at Julius-Maximilians-Universität Würzburg
Date December 19, 2016
Timeframe 4pm – 5pm
Location C 202 (Powerwall Room)

Can we design user interfaces that are intuitive to use, innovative and inclusive – all at the same time? Although it is generally doubted that this would be possible, we found great promise in the cognitive-linguistic theory of image-schematic metaphors. The talk introduces the theory and research into the application of image-schematic metaphors in HCI. Our research suggests that the application of image schemas can contribute to user interfaces that are innovative, inclusive and intuitive to use. Along the way I will highlight aspects of how we quantify innovation, intuitive use and inclusiveness.

Jörn Hurtienne is Professor of Psychological Ergonomics at Julius-Maximilians-Universität Würzburg (Germany). He received his PhD from Technische Universität Berlin (Germany) and previously was a Research Associate and EU Marie-Curie Fellow at the University of Cambridge (UK). His research interests include designing for intuitive use, tangible interaction, embodied cognition, and the psychology of knowledge work.

Back from CHI 2016

We are back from CHI 2016 and happy to present some impressions:

Harald Reiterer and Mario Schreiner co-organized Cross-Surface 2016, the second international workshop on interacting with multi-device ecologies “in the wild”:

Jens Müller talked about Virtual Objects as Spatial Cues in Collaborative Mixed Reality Environments: How They Shape Communication Behavior and User Task Load (PDF, Video)

Uta Hinrichs and Simon Butscher presented their paper Diving in at the Deep End: The Value of Alternative In-Situ Approaches for Systematic Library Search (PDF, Video).
Together with their co-authors Jens Müller and Harald Reiterer they received an Honorable Mention Award.

Ulrike Pfeil and Johannes Zagermann talked about When Tablets meet Tabletops: The Effect of Tabletop Size on Around-the-Table Collaboration with Personal Tablets (PDF, Video)

Thank you all for a great CHI’16, interesting talks and inspiring conversations!

Presentation of bachelor/master-project topics (HCI Group and Information Science Group)

The Human-Computer Interaction Group (HCI Group, and the Information Science Group (  cordially invite you to come to the introduction of this semester’s Bachelor and Master projects.

You will get a short overview on Monday, April 25 at 11:45 in our Media Room (Z 924).

The offered projects – in which students have the opportunity to actively participate in ongoing research – will be presented by members of the HCI and Information Science Group and can be discussed afterwards if any questions remain.

Invited Talk of Jakob E. Bardram: ‘Activity-based Collaboration for Interactive Spaces’ on March 3, 2016

We are pleased to welcome Jakob E. Bardram from the Technical University of Denmark as invited speaker on March, 3 2016. He will give a talk about “Activity-based Collaboration for Interactive Spaces”. The talk will be held at 5.00 pm in room ML 630.


Activity-based computing (ABC) have been proposed as a novel conceptual and technological framework for designing systems that provide more efficient user interaction. In ABC, rather than interacting directly with lower-level technical entities like files, folder, documents, etc., users are able to interact with ‘activities’ that directly map human work activities, and which encapsulates files and other low-level resources. In ABC an ‘activity’ can be shared between collaborating users and can be accessed on different devices. As such, ABC is a framework that suits the requirements of designing interactive spaces. This talk provides an overview of ABC with a special focus on its support for collaboration (‘Activity Sharing’) and multiple devices (‘Activity Roaming’). These ABC concepts are illustrated as implemented in two different interactive spaces technologies; ReticularSpaces [1] and the eLabBench [3, 2]. The talk discusses the benefits of activity-based collaboration support for these interactive spaces, while also discussing limitations and challenges to be addressed in further research.
