Glare from monitors measured with subjective scales and eye movements
Participants were confronted with four types of reflections on a computer screen, and the visual effects they experienced were recorded. The effects of non-glare, specular, diffuse and combined specular/diffuse reflexes were measured through eye movements, category scales and magnitude estimation. Two presentations, a picture and a text page were shown to the eight participants. The reflexes had no easily detectable effect on the eye movement variables, but had a significant effect on all the category scales. The specular reflex condition was always judged as the most disturbing. One eye movement variable, average velocity, had a significantly higher velocity for the picture. The eye movement variables and the category scales formed different factors in a factor analysis. Irritation appeared to be an important determing variable for the other scales.
