While previous studies have investigated the impact of frustration on computer users' mood as well as the causes of frustration, no research has ever been conducted to examine the relationship between computer frustrations and mood change for users with visual impairment. In this paper, we report on a study that examined the frustrating experiences and mood change of 100 participants, all with visual impairments, when they were browsing the web. The result shows that frustration does cause the participants' mood to deteriorate. However, the amount of time lost due to frustrating situations does not have a significant impact on users' mood, which is very different from the previous research on users without visual impairment. The impact on work seems to have the greatest impact on user mood.
