“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.

Eyes4ICU: 2 open positions in MSCA doctoral network

Exciting news! The geoGAZElab will be participating in the MSCA Doctoral Network “Eyes for Interaction, Communication, and Understanding (Eyes4ICU)” as an Associated Partner, funded by the Swiss State Secretariat for Education, Research and Innovation.

Eyes4ICU explores novel forms of gaze-based interaction that rely on current psychological theories and findings, computational modelling, as well as expertise in highly promising application domains. Its approach to developing inclusive technology by tracing gaze interaction back to its cognitive and affective foundations results in better models to predict user behaviour. By integrating insights in application fields, gaze-based interaction can be employed in the wild.

In the scope of Eyes4ICU, 12 doctoral candidates (DC) will be working at 7 different host institutions across Europe. Out of these, 2 DCs will be hosted at the geoGAZElab of ETH Zurich (PI: Peter Kiefer). They will be working on the topics Gaze-supported Trip Recommendation (DC6), and Gaze-supported Travel Experience Logging (DC12) respectively.

We are looking for two highly motivated doctoral candidates, starting at the earliest possible date: Position announcement.

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:

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.

Science City March 2018 – Impressions

The LAMETTA project has been demoed at this year’s “Treffpunkt Science City” event, an educational program of ETH Zurich for the general public where more than 3,000 visitors came.

Our panorama wall installation and the LAMETTA software allowed our visitors to experience as if they were exploring the view from a vantage point. Just by looking at the interested area (such as lakes, mountains and villages), our system can provide related information to the user.

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!
