Article in Scientific Reports: Mind Wandering

Do you enjoy touristic audio guides? You don’t? One reason could be that classic audio guides do not adapt to your cognitive state in real time.

In our most recent article in Scientific Reports, we investigate the detection of mind wandering from eye movements for combined audio-visual stimuli, such as touristic audio guides. We trained and validated classifiers which are able to successfully detect mind wandering in a 1-s time window. Future audio guides could use our results for providing more intelligent assistance.

Kwok, T. C. K., Kiefer, P., Schinazi, V. R., Hoelscher, C., & Raubal, M. (2024). Gaze-based detection of mind wandering during audio-guided panorama viewing. Scientific Reports, 14(1), 27955. https://doi.org/10.1038/s41598-024-79172-x

We wish you a fully focused (= non-mind wandering) reading experience!

This research is part of Tiffany Kwok’s (see former group members) doctoral thesis and an outcome of the LAMETTA project, which has been funded through an ETH Zurich Research Grant.

New Publication at COSIT 2024: Exploring Perceived Feasibility and Use Cases of 3D Sketch Mapping

Can you sketch in 3D?

Within the 3D Sketch Maps project, our former colleague, Prof. Kevin Gonyop Kim, and the geoGAZElab team investigated the perceived feasibility of 3D sketching in VR with a particular focus on the sketch mapping purpose. We interviewed 27 people from 3 domains and discovered that 3D sketching can help represent 3D information more effectively and complement the 2D approach. The paper was presented at the COSIT 2024 conference in September in Quebec City, Canada, by Prof. Martin Raubal and received attention and various questions. The full paper can be found here: https://doi.org/10.4230/LIPIcs.COSIT.2024.3.

New publication in the International Journal of Human-Computer Studies

The 3D Sketch Maps project team recently published a paper entitled:  VResin: Externalizing spatial memory into 3D sketch map. In this paper, we refined the concept of 3D sketch maps, proposed a technological framework using 3D Cartesian coordinate axes, and provided design criteria for 3D sketch mapping interfaces. We implemented a VR-based 3D sketch mapping tool called VResin, which is associated with traditional resin painting, and a layer-by-layer sketching interface that considers both researcher and user needs. We then conducted a comparative user study with 48 participants between mid-air sketching and layer-by-layer sketching interfaces for memorising multi-layered buildings. We found that VResin helps users to create less distorted sketches while maintaining the level of completeness and generalisation compared to mid-air sketching in VR. Finally, we presented application scenarios demonstrating how 3D sketch maps can support people’s externalisation of their 3D spatial understanding. This study is part of a Sinergia project called “3D Sketch Maps”, funded by the Swiss National Science Foundation (SNSF) [grant number 202284].

D-CEET project launched

We are excited to announce the start of D-CEET, a new project with Lufthansa Aviation Training (LAT), funded by the German Federal Ministry for Digital and Transport (BMDV) in the scope of the mFund innovation initiative.

Today, training for airline crew members takes place almost exclusively in elaborately reproduced cabin dummies and simulators, so-called CEETs (Cabin Emergency Evacuation Trainers). The aim of the D-CEET project is to fully replicate an Airbus A320 CEET as a “digital twin”. The resulting data model is intended to enable fully immersive training of all relevant training content in virtual reality (VR) and additionally as a tablet-based application.

In our sub-project, we will validate the effectiveness of the new training concept using eye tracking and other physiological sensors in systematic studies with crew members. We aim at validating the achievement of competence objectives by measuring and observing behavior as well as by measuring situational awareness and cognitive workload.

Read more about the D-CEET project in a recent press release by LAT, on our website, or on the BMDV website (German only).

New publication in the International Journal of Geographical Information Science

In our recently published study in Taylor & Francis Online, we investigated the influence of uncertainty visualization on cognitive load in safety-critical and time-critical decision-making tasks. This research tackles the ever-present challenge faced by professionals in various fields – making critical choices under pressure, often with inherent spatial uncertainties. We focused on identifying the most effective visualization techniques to support these decision-makers. Our study specifically examined the effectiveness of different uncertainty visualization techniques in traffic management tasks through eye tracking. Furthermore, through gaze transition entropy, we explore the differences between different strategies employed by the decision-makers. This research opens doors for further exploration in visualization design for decision support systems.

3D Sketch Map research meeting in Münster

The 3D Sketch Map project team had a very productive research meeting in Münster, thanks to Prof. Jakub Krukar for the perfect organization in this wonderful city! In this project, we investigate 3D sketch maps from a theoretical, empirical, cognitive, as well as tool-​related perspective, with a particular focus on Extended Reality (XR) technologies. Sketch mapping is an established research method in fields that study human spatial decision-making and information processing, such as navigation and wayfinding. Although space is naturally three-dimensional (3D), contemporary research has focused on assessing individuals’ spatial knowledge with two-​dimensional (2D) sketches. For many domains though, such as aviation or the cognition of complex multilevel buildings, it is essential to study people’s 3D understanding of space, which is not possible with the current 2D methods. In the research meeting, we exchanged our latest research outputs and future plans.

“Do You Need Instructions Again? Predicting Wayfinding Instruction Demand”

In collaboration with colleagues from TU Vienna, we have published a full paper in the proceedings of this year’s GIScience conference, taking place next week in Leeds, U.K.:

The demand for instructions during wayfinding can be considered as an important indicator of the internal cognitive processes during wayfinding. In the paper, we are predicting instruction demand in a real-world wayfinding experiment with 45 participants using different environmental, user, instructional, and gaze-related features. Being able to predict instruction demand can, for instance, be beneficial for navigation systems that adapt instructions in real-time, based on their users’ behavior.

New abstract in Resilience 2023- Using eye tracking for enhancing resilience in control rooms

We are pleased to announce that our abstract titled “Using eye tracking for enhancing resilience in control rooms” has been accepted for presentation at the Resilience 2023 conference.

In this abstract, we highlight three principle ways how eye tracking can support decision makers in control rooms: 1) Evaluation of information visualization for decision support systems, 2) unobtrusive assessment of decision-makers’ cognitive state, and 3) supporting distributed cognition through information sharing using eye-gaze.

In our talk, we’ll be presenting our current research progress in each of these directions. We look forward to seeing you at the Resilience 2023 conference in Mexico.

This project has received funding from the Future Resilience Systems program at the Singapore-ETH Center.

New Article Published in Human-Computer Interaction

Our article “Unobtrusive interaction: a systematic literature review and expert survey” has been accepted for publication by the Human–Computer Interaction (HCI):

Tiffany C.K. Kwok, Peter Kiefer & Martin Raubal (2023). Unobtrusive interaction: a systematic literature review and expert survey, Human–Computer Interaction, DOI: 10.1080/07370024.2022.2162404

Abstract. Unobtrusiveness has been highlighted as an important design principle in Human-Computer Interaction (HCI). However, the understanding of unobtrusiveness in the literature varies. Researchers often claim unobtrusiveness for their interaction method based on their understanding of what unobtrusiveness means. This lack of a shared definition hinders effective communication in research and impedes comparability between approaches. In this article, we approach the question “What is unobtrusive interaction?” with a systematic and extensive literature review of 335 papers and an online survey with experts. We found that not a single definition of unobtrusiveness is universally agreed upon. Instead, we identify five working definitions from the literature and experts’ responses. We summarize the properties of unobtrusive interaction into a design framework with five dimensions and classify the reviewed papers with regard to these dimensions. The article aims to provide researchers with a more unified context to compare their work and identify opportunities for future research.

The article will appear in one of the next issues of the Human–Computer Interaction. It has been published as Open Access and you can get the article here:
