This is one of the homepages of the device. The counters (2, 4) reflect how many washers and dryers are available for use. Available for use can either mean that someone else's close are sitting in the machine and need to be moved to a dryer, or it can mean that the machine is empty. To continue, the user needs to press either the "Claim Washer" or "Claim Dryer" button. Note that the workflow for washers and dryers is split very early on in the process.
In our scenario, Ginny needs to wash her clothes, so she presses the "Claim Washer" button. 
From this page, Ginny can see the names of the washers that are available, as well as select them by pressing the "Select" button. She can also press the "View on Map" button next to the name of each washer to see a map of the whole laundry space with the specific machine highlighted (this is not a feature that we have detailed in this scenario). Additionally, Ginny can view notes on each machine left by previous users. Ginny views the note on Washer 3.
