Their actions have been observed and listed out the observations for each scenarios and tasks. From the observation, inferences and insights are tabulated along with above information.
16.2 Quantitative evaluation : Incase of quantitative evaluation, it had been done based on the Usability testing tool developed by Prof. Anirudha Joshi. Then they were asked to perform the tasks and each user will be observed that how much time they take to complete the task, where they got stuck, which part they forgot, got confusion etc. Their performance was rated to do further analysis at last and decided the level of usability of the application among actual users. So, based on the tasks given during the qualitative evaluation, the usability levels are graded for rating of about 0-5. The grading has been done by self for the respective goal parameters. 48
