PolyFieldFor field officials
Field events, measured and on the scoreboard in seconds
PolyField is an app for the officials at each pit, circle and runway, and a results server for the whole meet. It connects to your EDM and runs on a dedicated Wi-Fi network. Use the app on its own, or with the server.
How it works
Measure once, and it's everywhere
-
The EDM
Measures where the throw or jump lands. No tapes, no numbers called across the field.
-
The app
The official confirms each attempt on a tablet: mark or foul, wind, bar height.
-
The server
Collects every event at the meet over a dedicated local network. Internet is only needed to link with your competition management system.
-
Everywhere
Scoreboards, announcers and results update as soon as an attempt is confirmed.
It links with OpenTrack and Athletics App, downloads start lists from Roster Athletics, and feeds PolyField Displays screens.
Network requirements
- A network of its own. Run PolyField on a dedicated network, separate from any guest or public Wi-Fi at the stadium.
- Devices must see each other. The network can't isolate devices (often called client or AP isolation) or split them into separate segments. App devices talk to PolyField Server, and screens talk to PolyField & Track Displays or Server, directly over the local network.
- Internet is optional. PolyField Server only needs it to link with your competition management system. PolyField & Track Displays never needs it.
Key features
Built for the officials on the field
-
Calibration wizard
Step by step: set the circle centre, check the edge against UK Athletics and World Athletics tolerance, then mark the sector line.
-
Multiple-event calibration
Calibrate several events and choose the right one for each. Javelin next to a discus and hammer circle? Calibrate all three up front and save the stress later.
-
Multiple jump boards
Calibrate every take-off board before the competition, then measure accurately from each with no mental maths. Long and triple jump, all boards in, once.
-
Accessible
Clear colours, large text and an optional voice read-out that speaks each result: bib, name, round and distance.
Internationally published
PolyField in IEEE Software
The engineering behind PolyField is published in IEEE Software, the international magazine of the IEEE Computer Society. The article explains how PolyField brings EDMs, apps, scoreboards and competition systems together into one real-time measurement system for track and field.

Heat maps
Every landing, mapped
The EDM measures where each throw lands, so every mark is plotted in the sector, athlete by athlete, with fouls alongside.
Coming to OpenTrack. OpenTrack will support these heat maps for meets run with PolyField.
With PolyField & Track Displays
Field events, live on the big screen
Officials record each attempt once, on a PolyField tablet or EDM. Athletes and spectators see it seconds later.
-
High jump and pole vault
The bar, every attempt and who is still in, with an animated reveal at each new height.
-
Long and triple jump
A ruler anchored to the pit, showing each mark against the top three and the average.
-
Throws
Every landing plotted in the sector, the competition best with a NEW BEST banner, and each athlete's round, position and best.
