An inverse-linear logistic model of the main sequence

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.

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.

Controllability matters: The user experience of adaptive maps

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.

Winter School 2016: Summary

Our Winter School on “Eye Tracking – Experimental Design, Implementation, and Analysis” is over. We were able to attract 61 participants, 5 speakers, plus several sponsor representatives.

In one keynote (Anke Huckauf), three lecture parts and three hands-on sessions (I. Scott MacKenzie, Andrew Duchowski, Izabela Krejtz, and Krzysztof Krejtz) participants learned about the whole cycle of performing eye tracking experiments, starting from experimental design, over data collection and processing, to the statistical analysis.

The conference center on Monte Verità (Ascona, Switzerland) offered an at the same time productive and enjoyable atmosphere with high quality food and service.

Thanks to all who have made this possible, especially our speakers and Congresso Stefano Franscini!

New SNSF Project: IGAMaps

Exciting research project to be started soon!

Our project proposal on “Intention-Aware Gaze-Based Assistance on Maps” (IGAMaps) has been approved by the Swiss National Science Foundation (PI: Peter Kiefer, Co-PI: Martin Raubal, 1 PhD for 3 yrs).

The project envisions intention-aware gaze-based assistance on cartographic maps. A future intention-aware gaze-based assistive map could, for instance, recognize from the user’s gaze that he or she is planning a touristic round trip, and adapt to the user’s needs accordingly. The main objective of this project consists in the investigation of methods for the recognition of activities and intentions from gaze data, collected from cartographic map users.

Master theses started

Two students have started their Master theses in the GeoGazeLab:

Aikaterini Tsampazi, a Master student in Geomatics, will use eye tracking to measure the visual behavior of wayfinders in a virtual environment in her Master thesis titled “Pedestrian Navigation: The use of navigation aids under time pressure in virtual urban environments”. The goal will be to investigate how pedestrian wayfinders behave under time pressure.

Yufan Miao, a Master student in Computational Science from Uppsala University, is visiting our group in spring and summer 2015. He will be working on his Master thesis on “Landmark detection for mobile eye tracking”, co-supervised by our group and the Chair of Photogrammetry and Remote Sensing (Prof. Schindler). The goal is to apply image processing techniques to outdoor eye tracking videos for the automatic computation of the object of regard.

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!
