Scenario:
Victoria, a coxen for MIT varsity 8 is taking her boat on a practice 2k before the race this weekend. This is a dry run for the race so she wants to record the data and act exactly as she will this weekend. She opens iCoxBox and sets up a new race. She toggles voice recording on so she can hear her voice, and names the new race "Practice 2k, March 2nd." She adds a few notes of encouraging phrases she wants to say during the race, such as "Let's take 10 strokes for MIT!" and "Come on girls, let's take a seat on Harvard!" (her rowers think these would help them during a race and she doesn't want to forget to say them). Her coach wants her to focus especially hard on keeping the stroke rate above 34 and ignore the splits for now (but she still wants the data recorded for review later).
Now that she is all set up, she puts her iPhone into it's place on the boat and tells her rowers to get ready. She starts the race in iCoxBox and tells her rowers to start. During the race, she keeps an eye on all the data and her notes, but her hands are busy steering so she can't modify the interface at all.
After they cross the finish line, she stops the race and saves it. The boat goes back to land and Victoria talks to Coach Jeff about the piece. They pull up the data and run through it in real time, listening to what Victoria says and taking note on how it affects the different numbers (split, stroke rate, accelerometer readings, etc). They decide that she should say "Let's take 10 strokes for MIT!" more often, especially near the middle third of the race, which is where the acceleration readings on the boat were lowest. Victoria sends the data to Jeff so that he can review it in more depth tomorrow morning on his copy of iCoxBox or on a computer.
