# Roundr Panel: An umpire panel that knows the laws

Panel turns a tablet into the umpire’s scoresheet. It follows the Laws of Badminton the way an umpire does, with service courts, ends, intervals and the calls to make, so the umpire can watch the rally instead of the paper.

## What it does

- **Two keys to score.** One key for each end of the court. The panel works out the server, the receiver, the service courts and the change of ends.
- **The right call at the right time.** The panel shows what to announce, from love all, play to game point and the result, in the words of the umpire’s federation.
- **Keeps scoring offline.** Every point is saved on the tablet first and sent when the network allows. A dropped connection never costs a rally.
- **Clocks for the officials.** The warm-up, the intervals, the time between rallies and any suspension are timed on the panel, with a warning before each one ends.
- **Cards and incidents.** Record faults, warnings and cards as they happen. Each lands on the scoresheet at the score it was given.
- **Undo without worry.** A wrong tap is one Undo away. The panel replays the match and puts the service courts right.

## Made for the umpire’s chair

Large keys, a court drawn to its real proportions and nothing to type during a rally. The panel runs in landscape on a tablet on the umpire’s chair, and an umpire who knows the laws needs no training for it.

It scores singles, doubles and wheelchair singles under three scoring systems, the familiar 21 points among them.

## Part of the tournament

At a tournament the tablet belongs to its court. It receives each match from the desk, shows the players and the rules the referee set, and sends every point to the server as it is scored.

If the server refuses something, the tablet says so and waits for the umpire or the referee instead of quietly changing the score.
