Prototype Iteration
Touch Interface
- We used to have buttons on the drawing pad that could be selected to indicate whether the current shot won or lost the point. We removed these and added them next to the drawing pad with clearer labels and also included a selection to indicate that the current shot did not end the point.
- We had a drop down menu on the drawing pad that was used to show possible gestures, and we replaced it with a help button.
- When a user selected a shot type from the help menu on the drawing pad, the gesture for that shot simply appeared on the pad. We then made it such that a small hand was drawing the gesture on the pad.
- We added labels to all the major sections of the interface, such as Video, Shot Type, Team A, Team B, and Shot Direction.
- We added labels to all the players to make it clearer that the numbers referred to a player.
- Substitutions used to be triggered by a long press on a player number, but now there is a substitution button corresponding to each team that brings up a substitution menu.
- Made it such that the direction of the shot could be indicated by a touch to the endpoints rather than just a swipe.
- The video used to run continuously. It now pauses while the user is entering a shot and continues when the user is done. This allows the user to not miss any action and catch up between points.
Command Line Interface
- We added labels to all the major sections of the interface, such as Video, Player, Shot, Direction, Point Outcome, and Previous Stats.
- Labeled the submit button.
- A small onscreen court is shown to indicate the names of all court positions. Input feedback regarding shot direction is now drawn on this court rather than on an unlabeled court that came up when a direction was input.
- The point outcome now defaults to the point continuing after the current shot.
- The video used to run continuously. It now pauses while the user is entering a shot and continues when the user is done. This allows the user to not miss any action and catch up between points.
- We used to have a single text box for inputting both endpoints of the shot, and now we have two separate, labeled ones.
