An usability and universal design investigation of parallax scrolling

Abstract

In this study, the usability and the universal design of parallax scrolling in a website was investigate with the help of experiment and two prototypes designed wholly for this research. The usability and universal design was evaluated with the help of factors like accuracy, efficiency and user satisfaction shown by the participants of the experiment while performing design tasks. Two different prototype websites were designed one with parallax scrolling and another without parallax scrolling. Tasks were designed in order to record the performance of participants and their opinion and feeling toward designed website. To measure the accuracy, efficiency (participant’s performance) and user satisfaction in this study, total time taken to complete tasks, total number of error done and participant’s opinion (post experiment questionnaire) were used. The data were collected after the experiment and those data were tested and analyzed with the help of statistical analysis tool and paired t-test method was used to test the data. From the analysis of the result of the test it was found that there was no significant difference in total task completion time, total number of errors done and participant’s opinion for websites with and without parallax scrolling. However, on average participants preferred parallax scrolling over non parallax scrolling website. From the findings of the study, it was concluded that there was no impact or improvement of usability and universal design of the parallax scrolling in a website.
