It is also important to note that when a user choose to focus on a poster, related posters are shown around it. After focusing on a poster, the user can add it to their calendar or share it by typing in an email address on the virtual keyboard. They can also make comments, scribble on it and like/dislike it using buttons just below the poster.
Analysis
The emphasis on a single interface suggests Design 1 will support both learning by doing and watching better than designs which rely on a supporting web interface due to the "one stop shop" nature it provides whereby all actions are carried out in public view. However, supporting additional actions results in an interface with reduced simplicity.
Learnability. The emphasis on a single interface suggests Design 1 will support both learning by doing and by watching better than designs which rely on a supporting web interface; however, supporting additional actions to make this possible decreases the simplicity. Specifically, the following positive (+) and negative (-) aspects are worth note.
Efficiency. Again, the emphasis on a single interface suggests an improved workflow-efficiency by providing a "one stop shop" for all user groups; however, this specific design constrains to a single input mechanism -- touch -- which may have reduced entry efficiency over traditional means such as a keyboard and mouse. Specifically, the following positive (+) and negative (-) aspects are worth note.
_Safety. _Specifically, the following positive (+) and negative (-) aspects are worth note.
Design 2
Modes of access: Website for adding and removing posters, electronic poster boards for viewing and interacting with poster board
...
Finally, like in all the other designs, the board allows interaction with the posters. In this design, the interaction buttons: sharing, calendar, liking/disliking and scribbling are overlaid on the poster.

The board loses card reader in design 2 and instead introduces automatically-generated QR codes that allow the viewers take a picture to add events to their calendar and share posters. Like in all designs, the poster board will allow scribbling on posters in addition to non-scribbling interaction with the polls and surveys.
