Abstract [en]

This study has investigated the suitability of the eye-tracker X2-30 from Tobii when measuring a student’s alertness level. To be able to determine the suitability of the X2-30 two different environments and two different subjects has been used. The environments were a lecture and webinars, and the two subjects were the two male authors of this study.

The results indicate that the eye-tracker X2-30 can be useful when it’s used under optimal circumstances (i.e. webinars), since it needs to have few disturbing factors when gathering data. These factors regard the subjects not moving out of the tracking area, i.e. the area of which the X2-30 is able to track the eye, and consequently it also means that the subject needs to be careful not to move the hardware. When used under optimal circumstances it was possible to obtain accurate data regarding pupil behaviour and somewhat accurate data regarding blink rate, making data relevant and the equipment suitable for measuring of alertness under the correct circumstances.

Abstract [sv]

Denna studie undersöker lämpligheten hos Tobii ABs X2-30 eye-tracker för att mäta en students vakenhet. För att avgöra lämpligheten så har tester gjorts i två olika miljöer och med två olika försökspersoner. Miljöerna var en föreläsning och ett flertal webinars medan försökspersonerna var de två manliga författarna av denna studie.

Resultaten indikerar att X2-30 kan vara användbar när den används under optimala omständigheter, det vill säga webinars, då den kräver så få störande faktorer som möjligt. Dessa faktorer rör utrustningens mätzon och att försökspersonen inte lämnar denna, samt att hårdvaran inte flyttas under mätning. När utrustningen användes under optimala förhållanden så var det möjligt att få precis data rörande pupillens beteende och ganska korrekt data rörande blinkfrekvens vilket gör utrustningen lämplig för mätning av vakenhet under rätt omständigheter.
