Based on the observed interaction with task 3, we decided to change our popover to reflect a 3-D button marked "Reply" instead of "Message User," as seen in our second prototype iteration. We also changed the "Leave your own note" caption to "Leave instructions," which is less likely to be confused for replying functionality.
Additionally, our first prototype iteration, testers found our use of the word "Idle" to be ambiguous (see observation above). For our second prototype iteration, we changes the label to read "Idle for X minutes", where X would be the amount of time since that particular washer finished its cycle. Testers found this to be preferable to the previous label. For further iterations, we are considering changing the text of the label to read "Finished X minutes ago", which we feel more clearly indicates the meaning of the label.
Finally, our first iteration had included a "View Map" button at the bottom of the design homepage. We found, however, that testers really didn't feel a need for this button, so we removed it for our second prototype iteration. Testers of the second iteration didn't seem to notice that the button was missing. Further discussion is needed to understand what functionality a "View Map" button would bring to our design before our design is implemented.
