Determining the Impact of Computer Frustration on the Mood of Blind Users Browsing the Web

Study conducted to examine the frustrating experiences and mood changes of computer users who are blind or have visual impairments. Participants were 100 blind users ranging in age from 18-81. Participants used screen readers such as JAWS and Window-Eyes to browse websites. Data was collected using time diaries, similar to surveys but requiring users to record what they are doing as they are doing it and noting the time of day it occurred. The time diaries consisted of pre- and post-session forms, one or more frustration experience forms, and a time log form, all entered in Rich Text Format in the user’s word processor. Participants recorded data about Web usage for a minimum of two hours, performing any web-based tasks that interested them. Forms recorded participants’ mood pre- and post-session. During the session, any frustrations were recorded on the frustration experience form, noting the cause of the frustration, current mood due to frustration, how they responded to the frustration, and how much time was lost. Overall time was also recorded. A multivariate hierarchical regression analysis was conducted on the collected data. Two hierarchical regressions tests were conducted and their results are discussed. The first test focuses on the impact of various factors on the change in overall mood. The second test investigates the factors that impact the frustration score in a particular session. Among the findings is that the mood of the blind users was not significantly affected by the amount of time lost when completing a task. This is directly contrary to users without visual impairments whose mood significantly deteriorates as the amount of time lost increases.
