If you don't have a smartphone it will be difficult for you to do this, but try creating a time- or location-based reminder using a keyboard interface. And I'm generously assuming that you're going to run this test at a computer, and not directly after bumping into someone in the hallway who reminds you about something you need to do.
This is a bit off-topic from the CAP thing, where I think it's reasonable assume that you are at a computer.
