Results of Question 1
In this part, 80% of participants performed the task successfully and 20% of them failed to complete the task.
6 out of 10 people did not return to the previous stage to perform this task along the way. It took them about 26 seconds to do this.
The last diagram is the performance path. One of the notable points in this diagram is that the ambiguity in design has led the users into the wrong path. The deviation has occurred in the selection page and the edit page.
Results of Question 2
The success rate of this task was 50%. At this stage, all individuals completed the defined function without returning to the previous steps. This indicates that users have not been ambiguous in performing this task and wrong selection is why they could not do the task successfully.
Participants did this task less than 11 second, it shows that this task was clear to them.
In this task, the first step error occurred on the home page. To prevent this error, we suggested defining access to the cutting tool in both the "gallery" and the "camera" path.
Results of Question 3
This task's success rate is 70%, and 50% of participants completed the task without returning to the previous steps.
They did this task in 31 seconds on average.
In the diagram, the most mistakes were made in the photo-editing step. Long access path to the edit page and repeating the "edit" phrase in this path were the main cause of errors. In order to minimize the possibility of errors, it should be possible for the users to skip the steps.
