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 facilitates in which 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.

Finally, several measures must be taken to mitigate safety issues associated with a consolidated interface which supports both posting and deletion. Specifically, the following positive (+) and negative (-) aspects are worth notenoting.

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.

_Efficiency. _SpecificallyThe addition of a supporting web interface in Design 2 facilitates the separation of user group actions thus increasing the simplicity of the primary display interface, but likewise introduces a discoverability issue as well as a coordination issue between the two interfaces which hinder learnability. In many ways, the separation of actions allow each user group to more efficiently interact with their primary interface -- event goers with the display, and event organizers and moderators with the web interface -- via input methods which support their actions; however, this also comes at the cost of the "one stop shop" experience provided by single interface designs. Finally, several steps must be taken to mitigate potential safety issues that arise as a result of two coordinating interfaces.

Design 3
Modes of access: Website for adding and removing posters, electronic poster boards and website for viewing and interacting with posters
...
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.
