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.

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.

Scientifica 2017 – Impressions

We have demoed the LAMETTA project at this year’s Scientifica, the Zurich science exhibition of ETH Zurich and University of Zurich with more than 30,000 visitors.

Our panorama wall installation enabled visitors to query information about lakes, mountains, and villages just by looking at them. Many visitors found the hidden treasure in the panorama and were rewarded with a piece of Swiss chocolate.

Visitors of all ages tried out and learned more about gaze-based interaction and mobile eye tracking technology. We are happy that so many people were interested and eager to discuss our research and potential applications to tourist guides of the future.

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!
