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 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:

Full Paper published at ICMI 2022

Our paper “Two-Step Gaze Guidance” has been published in the proceedings of the International Conference on Multimodal Interaction (ICMI ’22) as a full paper.

Tiffany C.K. Kwok, Peter Kiefer, Martin Raubal (2022). Two-Step Gaze Guidance, International Conference on Multimodal Interaction (ICMI ’22), DOI: 10.1145/3536221.3556612

Abstract. One challenge of providing guidance for search tasks consists in guiding the user’s visual attention to certain objects in a potentially large search space. Previous work has tried to guide the user’s attention by providing visual, audio, or haptic cues. The state-of-the-art methods either provide hints pointing towards the approximate direction of the target location for a fast but less accurate search or require the user to perform a fine-grained search from the beginning for a precise yet less efficient search. To combine the advantage of both methods, we propose an interaction concept called Two-Step Gaze Guidance. The first-step guidance focuses on quick guidance toward the approximate direction, and the second-step guidance focuses on fine-grained guidance toward the exact location of the target. A between-subject study (N = 69) with five conditions was carried out to compare the two-step gaze guidance method with the single-step gaze guidance method. Results revealed that the proposed method outperformed the single-step gaze guidance method. More precisely, the introduction of Two-Step Gaze Guidance slightly improves the searching accuracy, and the use of spatial audio as the first-step guidance significantly helps in enhancing the searching efficiency. Our results also indicated several design suggestions for designing gaze guidance methods.

Full Paper accepted at CHI 2019

Our paper “Gaze-Guided Narratives: Adapting Audio Guide Content to Gaze in Virtual and Real Environments” has been accepted by ACM CHI 2019 as a full paper:

Kwok, T.C.K., Kiefer, P., Schinazi, V.R., Adams, B., and Raubal, M. (2019) Gaze-Guided Narratives: Adapting Audio Guide Content to Gaze in Virtual and Real Environments. In CHI Conference on Human Factors in Computing Systems Proceedings (CHI 2019), ACM (accepted)

This paper proposes Gaze-Guided Narratives as an implicit gaze-based interaction concept for guiding tourists through the hidden stories of a city panorama. It reports on the implementation and evaluation of this concept which has been developed as part of the LAMETTA project. This research has been performed in collaboration between the GeoGazeLab, Victor R. Schinazi (Chair of Cognitive Science, ETH Zurich) and Benjamin Adams (Department of Geography, University of Canterbury).

Abstract. Exploring a city panorama from a vantage point is a popular tourist activity. Typical audio guides that support this activity are limited by their lack of responsiveness to user behavior and by the difficulty of matching audio descriptions to the panorama. These limitations can inhibit the acquisition of information and negatively affect user experience. This paper proposes Gaze-Guided Narratives as a novel interaction concept that helps tourists find specific features in the panorama (gaze guidance) while adapting the audio content to what has been previously looked at (content adaptation). Results from a controlled study in a virtual environment (n=60) revealed that a system featuring both gaze guidance and content adaptation obtained better user experience, lower cognitive load, and led to better performance in a mapping task compared to a classic audio guide. A second study with tourists situated at a vantage point (n=16) further demonstrated the feasibility of this approach in the real world.

LAMETTA at GeoSummit: Visit by Federal Councillor Guy Parmelin

We have presented the LAMETTA project at the GeoSummit in Bern (6-7 June 2018), the largest congress for geoinformatics, surveying and planning in Switzerland.

Federal councilor Guy Parmelin was one of the first visitors of our exhibit and was very interested in the innovative system. Due to his subsequent opening speech, there was no time to try out the gaze-based tourist guide to Lake Lucerne himself, but the short visit seemed already impressive.

A large number of visitors from both, industry and academia, visited our exhibit and tried out the system. In addition, our exhibit was part of the GeoSchoolDay – an event in conjunction with GeoSummit which introduces students at high school age to applications and opportunities of geo information technologies. Approx. 500 pupils visited LAMETTA and learned about eye tracking and its application in interactive systems.

Gaze-Informed Location Based Services

Our article “Gaze-Informed Location Based Services” has been accepted for publication by the International Journal of Geographical Information Science (IJGIS):

Anagnostopoulos, V.-A., Havlena, M., Kiefer, P., Giannopoulos, I., Schindler, K., and Raubal, M. (2017).  Gaze-informed location based services.  International Journal of Geographical Information Science, 2017. (accepted), PDF

The article introduces the concept of location based services which take the user’s viewing direction into account. It reports on the implementation and evaluation of such gaze-informed location based service which has been developed as part of the LAMETTA project. This research has been performed in collaboration between the GeoGazeLab, Michal Havlena (Computer Vision Laboratory, ETH Zurich) and Konrad Schindler (Institute of Geodesy and Photogrammetry, ETH Zurich).

Abstract
Location-Based Services (LBS) provide more useful, intelligent assistance to users by adapting to their geographic context. For some services that context goes beyond a location and includes further spatial parameters, such as the user’s orientation or field of view. Here, we introduce Gaze-Informed LBS (GAIN-LBS), a novel type of LBS that takes into account the user’s viewing direction. Such a system could, for instance, provide audio information about the specific building a tourist is looking at from a vantage point. To determine the viewing direction relative to the environment, we record the gaze direction
relative to the user’s head with a mobile eye tracker. Image data from the tracker’s forward-looking camera serve as input to determine the orientation of the head w.r.t. the surrounding scene, using computer vision methods that allow one to estimate the relative transformation between the camera and a known view of the scene in real-time and without the need for artificial markers or additional sensors. We focus on how to map the Point of Regard of a user to a reference system, for which the objects of interest are known in advance. In an experimental validation on three real city panoramas, we confirm that the approach can cope with head movements of varying speed, including fast rotations up to 63 deg/s. We further demonstrate the feasibility of GAIN-LBS for tourist assistance with a proof-of-concept experiment in which a tourist explores a city panorama, where the approach achieved a recall that reaches over 99%. Finally, a GAIN-LBS can provide objective and qualitative ways of examining the gaze of a user based on what the user is currently looking at.

ETH Zurich Research Grant

Great news right before the holiday season!

ETH Zurich will support our research on “Location-Aware Mobile Eye Tracking for Tourist Assistance” (LAMETTA) with an ETH Zurich Research Grant for a 3-year project, starting in 2015 (PI: Peter Kiefer).

The project will pioneer gaze-based interaction techniques for tourists in outdoor environments. The project envisions mobile assistance systems that trigger information services based on the user’s gaze on touristic areas of interest. For instance, a gaze-based recommender system could notify the observer of a city panorama about buildings that match her interest, given the objects she has looked at before. The main objective of this project consists in the investigation of novel gaze-based interaction methods for tourists exploring a city panorama.

Stay tuned for updates on LAMETTA!
