Final Design
In our final design, we settled for two main views for the PosterBoard:
...
When a poster is clicked on (in the calendar or similar events view), the poster is focused and the user is able to scribble on it, change scribbling color, view previous scribbles, continue a previous scribble, like/dislike a poster, add a reminder by swiping an RFID card and delete the poster by swiping a card too.
Motivations
In the course of our design, we made changes driven by comments in our paper prototype and heuristic evaluation. Our user testing also threw some insight on possible future improvements.
Paper Prototype
We changed the label "Clustered view" to "Similar Events View"
We forwent using QR codes for adding an event to a user's calendar settling instead for sending an email reminder to the user on swiping their RFID card.
One of the users could not find the button to select the poster file so we made sure that the button was clearly set apart with a sufficient color contrast
To exit from a focused poster, we allowed the user either click a close 'x' sign or click outside the focused poster.
Heuristic evaluation
Before the heuristic evaluation, we put in some animation that slid in the new week when scrolling weeks but it made posters disappear briefly before showing up the poster of the new week. An evaluator thought the behavior was jarring and we removed it.
An evaluator pointed out that there was no way to remove a poster added in error, for instance, so we implemented this critical authentication-based delete functionality
Some evaluators pointed out that since there were only two views (and hence, two buttons for switching between them), it wasn't obvious which view was selected despite our visual separation of the two. So, we added a border that made the selected view more obvious.
We added visual feedback to the like/dislike buttons so users could know how many likes/dislikes a poster has acquired
