iCoxBox GR1: Project Analysis
Andres Lopez-Pineda, Jesse Riemer, Taylor Gilbert
User Analysis
Rower
Physical limitation: No hands available to use interface
Motivation: Interested in retrieving relevant information, quickly
Environment: Will be used on a boat while rowing
Coxen
Physical limitation: No hands during race, since they will be needed for steering
Motivation: Interested in retrieving relevant information and saving it for review
Environment: Will be used on a boat while steering and communicating with rowers
Coach
Motivation: Interested in easily comparing data from multiple races
Environment: In a chase boat, so cannot directly interact with other boat, rowers, or coxen.
Our analysis is based primarily on interviews with a rower, coxen, and crew coach. In our interviews, they described the constraints on the use of an app like this and provided feedback as to what data is most important (this determined what we decided should be front and center and what can be in another tab on the interface).
Task Analysis
Access boat-related data in real-time
Goal: To monitor the status of the boat in order to communicate that to the rowers
Precondition: iPhone is secured to boat, in view of the user
Subtasks:
Once started, view all relevant information with minimal interaction
View pre-written notes
View ghost trail of current path and desired path
View stroke + accelerometer data
Toggle between on-boat and coach modes
If in coach mode, use a button to count strokes
Store race data
Goal: Save a set of data related to a race
Subtasks:
Set a ghost route if desired
Input notes to be viewed during the race
Decide if audio should be recorded
Press button to start race
View data (as in the task above) during the race
View timer for the race
Press button to end race
Have the data automatically be stored for later use
Change the name of the race afterwards
Replay race data
Goal: To be able to review race data at a later date
Precondition: the user has stored at least one set of race data
Subtasks:
Choose desired race out of a list of past races
View race data at any point in the race, with the different sets of data (stroke rate, timer, audio, etc) time-synced
Play/Pause/Rewind playback
