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.

  • 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.

DIS 2014

UHasselt-iMinds-EDM contributes (to) four papers at DIS 2014 covering design aspects of proxemics and mobile systems:

We also tried to submit a pictorial on making informed decisions on using (mobile) technology in museums, but it appears that reviewers expected more and I didn’t really grasp the concept of a Pictorial very well apparently. Nevertheless, we decided to share it anyway and hope it can be useful for some: Karel Robert, Kris Luyten, Jo Vermeulen and Karin Coninx. Introducing Technology in Museums: How to Start?.

UHasselt-iMinds HCI research at CHI’2014

The UHasselt-iMinds HCI researchers of the Expertise Centre for Digital Media will present a selection of their ongoing HCI research at the 32st ACM SIGCHI Conference on Human Factors in Computing Systems (CHI’2014). Four full conference papers were accepted for the highly competitive papers and notes track, the main archival track of CHI. Our work discusses tangible, affective and mid-air gesture-based interactions and contributes to creating more natural user interfaces that approach how we interact in real life.

At the conference we will present Paddle, the first prototype of a highly deformable mobile device that can be transformed into various special-purpose controls in order to bring physical controls to mobile devices. We will show what the effect is of a simple visualisation of participants stress during video-mediated collaboration and we hope future video-based collaboration systems can make use of such enhancements. We also present a study of how people interact with omni-directional video, a video format that we expect to become increasingly popular in the near future. As part of an internship and an intense collaboration of one of our PhD students with researchers at the Hasso Plattner Institute, Kickables will be introduced at the conference: the concept of tangibles that users can manipulate with their feet.

Besides these four papers our lab contributed to, Kashyap Todi — who just recently joined our team as a PhD student — co-authored a paper on Understanding Finger Input Above Desktop Devices while being at the Media Computing group at RWTH Aachen.

In addition to these full papers, our lab will present: a gamified version of our augmented piano setup at the interactivity venue, an initial exploration of interactive jacket buttons as an interactive poster, workshop papers on using heartbeats as explicit input and on help systems for gesture-based collaborative systems and a contribution to the alt.chi paper on Speculative Research Visions.

List of full papers at the conference:

  • Investigating the Effects of using Biofeedback as Visual Stress Indicator during Video-mediated CollaborationChiew Seng Sean Tan, Kris Luyten, Johannes Schöning, Karin Coninx.

    — This paper presents a thorough investigation on mental workload and stress perceived by twenty participants, paired up in an instructor-worker scenario, performing remote video-mediated tasks. The interface conditions differ in task, facial and biofeedback communication. Two self-report measures are used to assess mental workload and stress. Results show that pairs reported lower mental workload and stress when instructors are using the biofeedback as compared to using interfaces with facial view.

  • Multi-Viewer Gesture-Based Interaction for Omni-Directional Video, Gustavo Rovelo Ruiz (Hasselt University & Universitat Politècnica de València), Davy Vanacken, Kris Luyten, Francisco Abad (Universitat Politècnica de València), Emilio Camahort (Universitat Politècnica de València).

    — We present a gesture elicitation study in which we asked users to perform mid-air gestures that they consider to be appropriate for Omni-Directional Video (ODV) interaction, both for individual as well as collocated settings. We are interested in the gesture variations and adaptations that come forth from individual and collocated usage.

  • Paddle: Highly Deformable Mobile Devices with Physical Controls, Raf Ramakers, Johannes Schöning, Kris Luyten.

    — We present the concept of highly deformable mobile devices that can be transformed into various special-purpose controls in order to bring physical controls to mobile devices. Physical controls have the advantage of exploiting people’s innate abilities for manipulating physical objects in the real world. We designed and implemented a prototype, called Paddle, to demonstrate our concept.

  • Kickables: Tangibles for FeetDominik Schmidt (Hasso Plattner Institute), Raf RamakersEsben Pedersen (University of Copenhagen), Johannes Jasper (Hasso Plattner Institute), Sven Köhler (Hasso Plattner Institute), Aileen Pohl (Hasso Plattner Institute), Hannes Rantzsch (Hasso Plattner Institute), Andreas Rau (Hasso Plattner Institute), Patrick Schmidt (Hasso Plattner Institute), Christoph Sterz (Hasso Plattner Institute), Yanina Yurchenko (Hasso Plattner Institute), Patrick Baudisch (Hasso Plattner Institute).

    — We introduce the concept of tangibles that users can manipulate with their feet. We call them kickables. Unlike traditional tangibles, kickables allow for very large interaction surfaces as kickables reside on the ground.
