After our second round of prototyping, we discovered that our prototype did not handle some additional cases that would be simple to add. For example, if a person leaves a note, it is easy to contact them, but we did not handle the case where a user chooses not to leave a note but still should be contactable. We can fix this by adding "Message previous user" to the machine information panel (second picture under task 1) when there is no note that would be "from previous user".
The attempt at clarifying Idle put In order to clarify the label "Idle", we changed the text to "Idle for 10 minutes", intending to indicate that the machine had been waiting for some length of time with clothes still in it. This was still unclear, so in the next testing phase we want to put "Finished for 10 minutes" to make it quite clear that we mean the machine has finished running. Users thought that either the machine was broken, paused, or empty when we showed them the word "Idle", so we decided to remove this altogether.
