The purpose of the current investigation was to validate an automatic path change
feature developed for the ProZone3® system using a case study where a single
player was filmed during 97 minutes actual match play. The player’s path
changes were analysed in detail by a human observation process and compared to
the path changes determined by ProZone3®. A secondary aim was to validate the
times when the player entered different areas of the pitch that were recorded by
ProZone3®. There was a good strength of inter-observer agreement for the
human observation process for identifying path changes (κ = 0.71) and for the
pitch areas entered by the player (97.0% of areas entered were agreed within 1s).
There was a moderate strength of agreement between the human observers and
ProZone3® for path changes (κ = 0.41) with many of the disagreements being
expected given the limitations of human observation of movement. There was a
good strength of agreement between the human observers and ProZone3® for the
pitch areas entered (between 95.7% and 96.7% of areas entered being agreed)
with almost all of the disagreements being where a player was within 1m of the
border between 2 pitch areas.
