3. When users tried to exit from the detailed view of a poster, they couldn't figure out how to do it. They recommended adding an "X" to the top of the poster or allowing click outside the blown up area to escape the mode. One of the users attempted to pinch-zoom it.
Prototype Iteration
Based on our user testing, we found that the poster visualizations were easy for users to understand, however, they did not know what "Clustered view" meant. We therefore changed the button label. When adding a poster, users were confused by the steps required to add a poster (i.e. how to explore files on a USB etc). We changed the add poster flow as below. Almost all users were not interested in using QR codes for adding events to their calendars. As a result, we removed them from the design. Users were also unsure about how to switch from the detailed view of a single poster to the original overall view. So we added an "X" to the right upper corner of posters in the detailed view.
1. We changed the label for the 'clustered view' to 'by topic'
