Abstract [en]

Eyetracking is a technique developed to register a persons eye movements. The data collected from an eyetracking session is a set of points on a plane, on which the person has looked at. When large amounts of data have been collected, the simple dot representation of the data is not sufficient to recieve a good overview of the result. The need for a better data representation therefore arises.

This report presents a model for a heatmap generator. Each point is given radial mass, where the highest mass is in the center of the point. Each value is then translated into a color and an alpha value.

An implementation of the model has been made in C# and the results are described and discussed in the report.

Abstract [sv]

Eyetracking är en teknik utvecklad för att registrera en persons ögonrörelser. De uppgifter som samlas in från en eyetracker-session är en uppsättning av punkter på ett plan, som personen har tittat på. När stora mängder data har samlats in, räcker det inte med en enkel punktrepresentation för att få en god överblick av resultatet. Behovet av en bättre datarepresentation uppstår därför.

Denna rapport presenterar en modell för en heatmapgenerator. Varje punkt ges en radiell massa, där den högsta massan är i centrum av punkten. Varje värde omvandlas sedan till en färg och ett alfa värde.

En implementering av modellen har gjorts i C# och resultaten beskrivs och diskuteras i rapporten.
