We’re excited to demonstrate the LAMETTA project at ETH Treffpunkt Science City, the educational programs of ETH Zurich for all. Come and try out an interactive mobile eye tracking system! Explore a mountain panorama and interact with it only by using your gaze (more details)!
You can find us Sunday, 25 March in ETH Hönggerberg HCI, Room E2.
Have you ever thought of eye tracking data as spatial “big” data? Are you collecting large amounts of eye tracking data together with geo-spatial coordinates, or are you applying machine learning on such data? Then the workshop on “Spatial Big Data and Machine Learning in GIScience” at this year’s GIScience conference in Melbourne might be interesting for you.
The 1st Call for Papers is now available on the website.
We’ll present our ideas on how to enrich a tourist’s experience with gaze-guided narratives at a CHI workshop in Montreal this year:

Dr. Ioannis Giannopoulos received the ETH Zurich Culmann Award in 2017 for an outstanding doctoral thesis “Supporting Wayfinding Through Mobile Gaze-Based Interaction”.
Peter Kiefer and Ioannis Giannopoulos have contributed to an article titled “An inverse-linear logistic model of the main sequence” (Journal of Eye Movement Research, JEMR). It is now available online:
http://dx.doi.org/10.16910/jemr.10.3.4
Abstract. A model of the main sequence is proposed based on the logistic function. The model’s fit to the peak velocity-amplitude relation resembles an S curve, simulta- neously allowing control of the curve’s asymptotes at very small and very large amplitudes, as well as its slope over the mid amplitude range. The proposed inverse-linear logistic model is also able to express the linear relation of duration and amplitude. We demonstrate the utility and robustness of the model when fit to aggregate data at the small- and mid-amplitude ranges, namely when fitting microsaccades, saccades, and superposition of both. We are confident the model will suitably extend to the large-amplitude range of eye movements.
We’re glad to announce the 3rd International Workshop on Eye Tracking for Spatial Research (ET4S), which will take place January 14, 2018 in Zurich.
The workshop aims to bring together researchers from different areas who have a common interest in using eye tracking for research questions related to spatial information. This is the 3rd edition of the workshop, after two successful ET4S workshops in Scarborough (2013) and Vienna (2014). This time the workshop will be co-located with the 14th International Conference on Location Based Services (LBS 2018).
The workshop will be opened with an invited talk given by Roman Bednarik, an adjunct professor at the School of Computing, University of Eastern Finland.
The Call for Papers is now available (Paper submission deadline: September 27, 2017).
ET4S 2018 is supported by Ergoneers.
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.

A double Special Issue on “Eye Tracking for Spatial Research” in Spatial Cognition&Computation, guest-edited by Peter, Ioannis, Martin, and Andrew Duchowski, has appeared [URL].
Nineteen manuscripts were submitted to an open Call for Submissions, out of which seven were finally accepted after a rigorous review process.
The Special Issue commences with an overview article, authored by the Guest Editors: “Eye tracking for spatial research: Cognition, computation, challenges” [URL, PDF].
On the 28th of November Martin Raubal, Peter Kiefer and David Rudi from the GeoGazeLab co-hosted a project presentation of the “Awareness in Aviation” project in collaboration with SWISS International Air Lines Ltd.
During that event the project and its goals was first presented to a wider audience consisting of guests from SWISS International Air Lines Ltd., Swiss Aviation Training, the Swiss Federal Office of Civil Aviation (BAZL) and journalists from different news journals. One of the journals was the “My SWISS” magazine, which recently published an article of the event.
An article titled “Controllability matters: The user experience of adaptive maps” will appear in one of the next issues of the Geoinformatica journal. It is now available online:
Controllability matters: The user experience of adaptive maps
Abstract Adaptive map interfaces have the potential of increasing usability by providing more task dependent and personalized support. It is unclear, however, how map adaptation must be designed to avoid a loss of control, transparency, and predictability. This article investigates the user experience of adaptive map interfaces in the context of gaze-based activity recognition. In a Wizard of Oz experiment we study two adaptive map interfaces differing in the degree of controllability and compare them to a non-adaptive map interface. Adaptive interfaces were found to cause higher user experience and lower perceived cognitive workload than the non-adaptive interface. Among the adaptive interfaces, users clearly preferred the condition with higher controllability. Results from structured interviews reveal that participants dislike being interrupted in their spatial cognitive processes by a sudden adaptation of the map content. Our results suggest that adaptive map interfaces should provide their users with control at what time an adaptation will be performed.
The latest issue of the Horizonte magazine, published by the Swiss National Science Foundation, is reporting on our research.

Martin Raubal was invited for the INNOLEC Lecture at the Department of Geography of the Masaryk University Brünn, Czech Republic.
The title of his talk is: Gaze-based assistance for wayfinders in the real world (slides as PDF, all our presentations).
GeoGazeLab was represented at the Smarttention Workshop at MobileHCI to raise awareness for visual attention in adaptive interfaces.
Thanks to the organizers for their great work. We had inspiring discussions about the future of mobile UIs.
The past years have seen a growing interest in augmenting human cognition – attention, engagement, memory, learning, etc – through ubiquitous technologies. With the ongoing research and development of near-constant capture devices, unlimited storage, and algorithms for processing and retrieving captured recordings, the resulting personal “lifelogs” have opened the door to a vast range of applications. In the third rendition of this workshop series, we focus on technologies and applications of capturing and integrating personal experiences into everyday use cases. With the question What constitutes a modern lifelog?, we would like to invite researchers, designers, and practitioners to envision and exchange ideas on how ubiquitous technologies and applications can help enhance human cognition in everyday life. For example, search requests may no longer purely retrieve information from online archives, but take into account personal experiences. In this one-day workshop, we would like to formulate visions and concrete application scenarios for making use of ubiquitous technologies in order to push personal data to an application layer where it is used to support and augment human cognition and the human mind.
