The Distributed and Interactive Systems group from Centrum Wiskunde & Informatica (CWI) will be present at CHI 2019 presenting three full papers: (1) a paper on measuring photo sharing experiences in social virtual reality (2) a paper that provides a comparison of unimodal navigation cues for child cyclists, and (3) a paper on sustained spatial relationships between hands and surfaces reveal anticipated action. We will additionally showcase our research on two case-studies, one on object-based broadcasting at the FA Cup in Wembley Stadium, and the other on a model-driven design approach for video-comparisons. CHI is the flagship conference of ACM SIGCHI, the premier international society for professionals, academics and students who are interested in human-technology & human-computer interaction.

Our first full paper investigates photo sharing experiences in immersive social Virtual Reality (socialVR) environments. A controlled, within-subject study was conducted to compare photo sharing under face-to-face (F2F), Skype, and Facebook Spaces conditions. We found that socialVR can closely approximate F2F sharing. We contribute empirical findings on the immersiveness differences between digital communication media, and propose a socialVR questionnaire that can in the future generalize beyond photo sharing.

Our second full paper investigates navigation systems for child cyclists, which are distracting and challenging for children. Different unimodal cues were tested where we explored their suitability for child cyclists through two experiments. In the first experiment, we developed an indoor bicycle simulator and compared auditory, light, and vibrotactile navigation cues. In the second experiment, we investigated these navigation cues in-situ in an outdoor practice test track using a mid-size tricycle. To simulate road distractions, children were given an additional auditory task in both experiments. We found that auditory navigational cues were the most understandable and the least prone to navigation errors. However, light and vibrotactile cues might be useful for educating younger child cyclists.

Andrew Webb, an ERCIM Postdoctoral Fellow in DIS, will present a third full paper that investigates user bimanual interaction behaviors. Observations of landscape architecture students use of a bimanual pen and multi-touch environment revealed a new phenomenon—interstices. Their bimanual interactions involved various sustained hand gestures, interleaved between their regular commands. Positioning of the non-preferred hand indicates anticipated actions, including: sustained hovering near the surface; pulled back but still floating above the surface; and resting in their laps.

The first case study reflects on the successful deployment of the infrastructure from the EU-funded project 2-IMMERSE at the FA Cup final at Wembley stadium in London. During the trial, an end-to-end system for object based broadcasting was set up in the press area of the stadium and we replicated the BT Sport coverage using our system, inserting broadcast objects on-demand into the live stream and broadcasting the match over the Internet using our system.

Atima Tharatipyakul, an intern in DIS, will present the second case study that discusses development of a theoretical model for designing user interfaces to support video comparison - one of the most basic cognitive activities we engage in everyday life. The paper presents a design originated from the model and an informal user study, which demonstrates the model’s potential for future research of applications that depend on video comparison.

Join us in Glasgow!

Before that, the group is organising a pre-CHI day, a free 1-day event where people who will be presenting at CHI can practice their presentation and get feedback. This can be a paper presentation, case study, poster (LBW)…
