Experiences from the Use of an Eye-Tracking System in the Wild - PowerPoint PPT Presentation

Experiences from 
 the Use of 
 an Eye-Tracking System 
 in the Wild � Kuparinen Liisa, Irvankoski Katja �

2 � Objectives of the study � To resolve the suitability of the eye-tracking method for the research in the wild � To form a research framework for the use of eye- tracking systems in the wild � To point the issues that need to be considered when planning a study with eye- tracking system in the wild � Experiences from the Use of an Eye-Tracking System in the Wild.

3 � Why eye-tracking? � independence indication of of data from problem solving user ʼ s memory � strategies � information large amount of about the gaze data � objects � Experiences from the Use of an Eye-Tracking System in the Wild. Observing the Mobile User Experience. 17.10.2010. �

4 � Test setting � Finnish forests � Varying weather conditions � SMI ʼ s eye-tracking system � • Cameras on a helmet � • Laptop on a backpack � Three users � Specific tasks + interviews � Experiences from the Use of an Eye-Tracking System in the Wild.

5 � Test tasks � • Walk according to the given guidance � • Describe what you see � • Describe what objects you used to locate yourself � Without • Describe the route walked through � map � • Walk according to the given guidance � • Locate yourself on the map � With mobile • Navigate on foot to a location pointed on the map � map � Experiences from the Use of an Eye-Tracking System in the Wild.

6 � Challenges with data quality � Gaze objects on varying distances in same direction � Parallax problem � Calibration � Defining Areas of Interest � Experiences from the Use of an Eye-Tracking System in the Wild. Observing the Mobile User Experience. 17.10.2010. �

7 � Challenges with experimental conditions � Mobility with an eye- tracking system � User ʼ s eyes � Weather + lighting conditions � Battery capacity � Pictures from SMI’s and Tobii’s web sites Experiences from the Use of an Eye-Tracking System in the Wild.

8 � Fixation versus attention � Recognition test: � • After walk a set of 16 pictures was shown. � • Task: recognise which are from the route. � • Only couple went right � Cognitive processes � • Eye-movements may be an indication of shift in attention. � • Attention may be shifted without eye-movements. � Experiences from the Use of an Eye-Tracking System in the Wild.

9 � Conclusions � Access to data that can not be reached by any other method � • Though a need for complementary methods � Essential to be aware of the problems � • Some issues are easy to take into account � • Some are in the need of technical development of eye-tracking systems � A need to study more eye-tracking in the wild � • To validate these findings � • To resolve the other suitable use cases and conditions � Experiences from the Use of an Eye-Tracking System in the Wild.
