Objectives of the study

Experiences from the Use of an Eye-Tracking System in the Wild. Observing the Mobile User Experience. 17.10.2010. 2

To resolve the suitability of the eye-tracking method for the research in the wild To point the issues that need to be considered when planning a study with eye- tracking system in the wild

To form a research framework for the use of eye- tracking systems in the wild

independence

  • f data from

userʼs memory indication of problem solving strategies information about the gaze

  • bjects

large amount of data

Test setting

Finnish forests Varying weather conditions SMIʼs eye-tracking system

  • Cameras on a helmet
  • Laptop on a backpack

Three users Specific tasks + interviews

Test tasks

Without map

  • Walk according to the given guidance
  • Describe what you see
  • Describe what objects you used to locate yourself
  • Describe the route walked through

With mobile map

  • Walk according to the given guidance
  • Locate yourself on the map
  • Navigate on foot to a location pointed on the map

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.

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
