Harald Reiterer at Dagstuhl Seminar “Ambient Notification Environments”

This week, Prof. Dr. Harald Reiterer attended a Dagstuhl Seminar on “Ambient Notification Environments“.

Presentation of Bachelor/Master-Project Topics

This semester we offer a number of Bachelor and Master projects in which students have the opportunity to actively participate in ongoing research projects.

We, therefore, cordially invite you to come visit us in our MediaRoom (Z924) on Monday, April 24th at 11.45 am.

There you will get an overview of open Bachelor and Master projects.

The projects will be presented by members of the HCI Group and can be discussed afterwards if any question remains.

If you’re interested in the study profile “Interactive Systems” and the projects we offer, we highly recommend you to get familiar with the guidelines in advance:

Papers and Note accepted for CHI ’17

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.

Short Bio

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.

Talk at PIT Symposium in Aarhus

Harald Reiterer has been invited to give a talk about “Technologies for supporting participation during search” at the 2016 Fall PIT Symposium in Aarhus. More about the Symposium:

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!
