UHasselt-iMinds-EDM HCI research at CHI’2015

UHasselt-iMinds HCI research at CHI’2015

The UHasselt-iMinds HCI researchers of the Expertise Centre for Digital Media will present a selection of their ongoing HCI research at the 33rd ACM SIGCHI Conference on Human Factors in Computing Systems (CHI’2015). Two full conference papers and one note were accepted for the highly competitive papers and notes track, the main archival track of CHI. Our work this year discusses, amongst other things, end-user development of interactive paper using printed electronics, social signal processing techniques to improve presentation skills, a new approach for private online communication, new work on space usage rules, interaction with smartwatches and end-user fabrication for smart homes.

In addition to these papers, our lab will present one alt.chi contribution, two Work-In-Progress papers, five workshop contributions and we’ll have a setup at the interactivity venue.

List of full papers and notes at the conference:

  • You Can’t Smoke Here: Towards Support for Space Usage Rules in Location-aware TechnologiesPavel Samsonov, Xun Tang, Johannes Schöning, Werner Kuhn, Brent Hecht.

    — Recent work has identified the lack of space usage rule (SUR) data – e.g. “no smoking”, “no campfires” – as an important limitation of online/mobile maps that presents risks to user safety and the environment. In order to address this limitation, a large-scale means of mapping SURs must be developed. In this paper, we introduce and motivate the problem of mapping space usage rules and take the first steps towards identifying solutions. We show how computer vision can be employed to identify SUR indicators in the environment (e.g. “No Smoking” signs) with reasonable accuracy and describe techniques that can assign each rule to the appropriate geographic feature.

  • PaperPulse: An Integrated Approach for Embedding Electronics in Paper Designs. Raf Ramakers, Kashyap Todi, Kris Luyten.

    — We present PaperPulse, a design and fabrication approach that enables designers without a technical background to produce standalone interactive paper artifacts by augmenting them with electronics. With PaperPulse, designers overlay pre-designed visual elements with widgets available in our design tool. PaperPulse provides designers with three families of widgets designed for smooth integration with paper, for an overall of 20 different interactive components. We also contribute a logic demonstration and recording approach, Pulsation, that allows for specifying functional relationships between widgets. Using the final design and the recorded Pulsation logic, PaperPulse generates layered electronic circuit designs, and code that can be deployed on a microcontroller. By following automatically generated assembly instructions, designers can seamlessly integrate the microcontroller and widgets in the final paper artifact.

  • Augmenting Social Interactions: Realtime Behavioural Feedback using Social Signal Processing Techniques. Ionut Damian, Chiew Seng Sean Tan, Tobias Baur, Johannes Schöning, Kris Luyten, Elisabeth André.

    — Nonverbal and unconscious behaviour is an important component of daily human-human interaction. This is especially true in situations such as public speaking, job interviews or information sensitive conversations, where researchers have shown that an increased awareness of one’s behaviour can improve the outcome of the interaction. With wearable technology, such as Google Glass, we now have the opportunity to augment social interactions and provide realtime feedback on one’s behaviour in an unobtrusive way. In this paper we present Logue, a system that provides realtime feedback on the presenters’ openness, body energy and speech rate during public speaking. The system analyses the user’s nonverbal behaviour using social signal processing techniques and gives visual feedback on a head-mounted display. We conducted two user studies with a staged and a real presentation scenario which yielded that Logue’s feedback was perceived helpful and had a positive impact on the speaker’s performance.

Several contributions are co-authored with HCI master students that took part in our course “Trends in HCI” (Actuele trends in HCI) at Hasselt University (which is taught by prof. dr. Johannes Schöning). Congrats to these students: Wouter Van Vlaenderen, Jens Brulmans, Debbie Gijsbrecht, Stein Smeets and Erasmus students Jacqueline Galeazzi and Juan José Martín Miralles!
