Abstract
To effectively utilize a gaze tracker in user interaction it is important to know the quality of the gaze data that it is measuring. We have developed a method to evaluate the accuracy and precision of gaze trackers in virtual reality headsets. The method consists of two software components. The first component is a simulation software that calibrates the gaze tracker and then performs data collection by providing a gaze target that moves around the headset's field-of-view. The second component makes an off-line analysis of the logged gaze data and provides a number of measurement results of the accuracy and precision. The analysis results consist of the accuracy and precision of the gaze tracker in different directions inside the virtual 3D space. Our method combines the measurements into overall accuracy and precision. Visualizations of the measurements are created to see possible trends over the display area. Results from selected areas in the display are analyzed to find out differences between the areas (for example, the middle/outer edge of the display or the upper/lower part of display).
