| Globally feedback was positive. The testers managed to use the prototype without having too much trouble identifying the right action for their intensions. On the usefulness side of things, there were no real test, but the general opinion is that the reporting features as well as the versioning and layers features may certainly help in providing value over the paper based static solution. | Globally feedback was positive.

| To see if the prototype is useable and could be useful on a projected wall, this mainly in the intent to be as near as possible to the original sticky note experience, it was first tested on Tablet PC. Tablet PC gives the user the same display size as the normal screen experience, but instead of using a mouse the user can directly manipulate the objects on screen with a pen. This first experience revealed that most of the action are working as well as with the mouse, or even easier for some drag and drop operations. Naturally since the keyboard is still available it is the preferred input method for text, even if handwriting recognition is available. As explained in the technical chapter, early on such a test revealed that click interactions are somewhat imprecise and have to be taken into consideration for detecting the double click actions. | To see if the prototype is useable and could be useful on a projected wall, this mainly in the intent to be as near as possible to the original sticky note experience, it was first tested on Tablet PC.

| As for the usability, it has become clear that touch solution are even more approximate for registering clicks and pointer location. For example, involuntary perspective collapse occurred frequently due to unintentional clicking on empty space of a perspective. Link selection was nearly impossible since the highlighting of a link is required and occurs only if the cursor is exactly over it. | As for the usability, it has become clear that touch solution are even more approximate for registering clicks and pointer location.
