UHasselt-iMinds-EDM at CHI 2014

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.


The future of software tools to support collaborative design

As part of a European research project COnCEPT, we are conducting a survey on the professional practices of designers. Our aim is to develop a set of software tools designed to support remote collaboration among the members of professional design teams. If you are involved in any type of design, please respond to our survey at http://goo.gl/MF3StK which should take approximately 15 minutes to complete. Respondents of the survey can win a gift certificate and will be informed about the project as it develops.
