Briefing
Thank you for volunteering to test our prototype for recording volleyball statistics.

- 1 of 3 users did not know where to start
- 1 of 3 users could not find where to enter shot type
- 1 of 3 users could not find where to indicate which player made the current shot
- 1 of 3 users could not understand mapping between gesture and shot type
- 1 of 3 users tried to enter shot direction by tapping on the shot's start and end points in the shot direction view
- 1 of 3 users could not figure out what to do with the drawing view
- 1 of 3 users forgot to enter whether the current shot ended the current point
Command Line Interface
- 1 of 3 users tried to enter the start position of the shot without indicating which team made the shot
- 1 of 3 users was confused by the direction of the arrows for the menus on each of the input fields
- 1 of 3 users tried entering data about the shot by clicking on the space for the picture above the input field
- 1 of 3 users was confused by the unrealistic players numbers used on the prototypes
- 1 of 3 users had trouble efficiently mousing through the player selection menu because it was too thin
- 1 of 3 users was confused by the picture of the spike that came up after indicating that the current shot was a spike
- 1 of 3 users typed 1 instead of w for the point scored input field
- 1 of 3 users thought that se was the shortcut for serve
- 1 of 3 users was confused about the usefulness of the video feed
Note that, for both interfaces, all the issues we found were concerned with learnability, even though we included a test that asked users to perform a task as quickly as they could. This may be due to the fact that the testing environment had less pressure than an actual game and that the user only had to enter a single stat quickly, not many. We plan to gather more information about efficiency and safety issues in the future by performing more tests with actual game footage.
