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.
Design 1:
Main opening screen. From here, Victoria can choose an existing race, or start a new one
screen 1:
learnability: all affordances on the screen
efficiency: tapping is quick and easy
visibility: login state is visible on button and below, number of saved races/trails you have is visible
Err: nothing is irreversible
This is the create a new race screen. She is able to enter the title of the race and adjust each of the items in the menu at will by a direct manipulation drag and drop. From here she can start the race. When she does, the thumbs disappear and the interface is locked-in and recording data.
screen 2:
learn: affordances for dragging, deleting
eff: all things on screen, no dropdowns, quick and easy modifications
vis: all initial data bars are visible, and this is the look of the screen for when you start a race. bad things: ghost trail is hidden unless you are changing it. can't change audio from here (it's in settings)
err: nothing gets deleted, and movements can always be reversed
Before she can follow a ghost trail, she must select it. This is the screen that appears when she clicks on the inside of the "Follow Ghost" UI element. She can accept her choice or cancel to return to the race recording screen.
screen 3:
learn: choosing ghost trail shows in map.
eff: scrolling through list could be tedious with lots
vis: check mark next to chosen trail and previous
err: can come back in and rechoose if necessary
Screen 4 is the same as screen three, but in Race mode, where the interface is locked and displaying real-time data.
screen 4:
learn: only two buttons, everything else is static
eff: you shouldn't be editing anything,
vis: any data not on the first screen is hidden unless you scroll, which most likely wont be done in a race
err: shouldnt be interacting unless you want to end a race, but race ending is final.
To save a race after it has been run. This appears when she stops the recording.
screen 5:
learn: modal interface shows that you can only edit race name
eff: if you want to just use the default and go on, you still need to use this view
vis: previously entered race name is shown to user
err: can always change name later
...
learn: It is easy to determine which actions are available
Eff: You can't compare or copy other configs
Vis: This view is exactly how the race config will appear when you are racing. You can't see the notes for the race unless you are editing them.
Err: you can move elements around, which is reversible. removing/adding elements is reversible. The only irreversible action, beginning the race, is close to other buttons, which may lead to errors.
Screen 5: Once the race starts, the chosen configuration screen is no longer editable and begins showing data.
...
Screen 7: When the user presses playback on the summary screen, he/she is shown this screen. It shows the editable race configuration screen, but with added playback controls so he/she can play/pause and scan forward/backward through the race data. He/she can also add/remove plots of data while the race is playing.
Learn: This is the same view as during the race
Eff: Same as other views with reversible actions. Comparing lots of data views involves adding/removing plots, which isn't efficient
Vis: All chosen state info is on the screen, you can add/remove other data if you want
Err: All actions are reversible.
Design 3:
This is the home screen of our tab-bar interface. This is where victoria can select a new race or to replay an old one.
