Event Viewer

This feature allows you to easily find the events (e.g. all shots) of a match. The selected events can be reviewed within the 2D and video player. Combining event-data with position-data and video allows you to analyze events both quantitatively (how many times did an event occur) and qualitatively (detailed per event). Since both the 2D visualization as well as the video are equipped with a forward and backward play function, all events are easily reviewed.

Synchronized Events

In the improved Event Viewer (released in February 2021) we now display synchronized events. This means that we use both event data and tracking data in order to provide the defined events. This allows you to analyze events in combination with tracking data, with increased reliability of event attributes.

For example, for a pass, we know at the very least what player(s) is/are involved, where on the field the event approximately happened, and when it approximately happened. Based on that information, we can search for a position data snapshot that is compatible with that situation and correct the timestamp and positions accordingly.

At the moment we distinguish 39 events that can be attributed to a single player and can therefore be interpreted as 'player actions'.

Benefits of synchronized events

As you can imagine, combining event data with tracking data has a huge potential and opens up many possibilities. A small selection of the benefits we see:

  • Thanks to the synchronization, actions have a more accurate timestamp.

  • The position on the field is now the actual position of the action and not dependent on (error-prone) notational analysis.

  • Distances are more accurate of players and the ball (eg pass distance).

  • Corrects for erroneous events (eg wrong player).

  • Improved display of actions in 2D and video player.

  • More relevant attributes/information are available for each action.

  • And many more... We would be happy to discuss the possible applications of this development with you.
