World Cup 2026 Offside Technology: AI, Computer Vision, and the Connected Ball

The 2026 FIFA World Cup will feature an advanced semi-automated offside technology (SAOT) combining a connected ball with IMU sensors, multi-camera computer vision, and player-specific 3D digital twins to improve the speed and accuracy of offside decisions. The system provides automatic audio alerts for clear offsides while leaving complex scenarios to human referees.

Key points

  • The connected ball contains an IMU that samples at 500 Hz to precisely timestamp touches via acceleration and angular velocity spikes.
  • Multi-camera pose estimation tracks player keypoints and uses personalized 3D models for more accurate offside line measurement.
  • Clear offside situations trigger automatic audio alerts to on-field officials, but subjective calls like interference remain with the VAR.
