Computer Vision Ball-Tracking Already Eliminating Roles
#1Hawk-Eye Innovations (owned by Sony) has deployed its Live Electronic Line Calling (ELC) system across all ATP Tour, WTA Tour, and Grand Slam events, resulting in the complete elimination of the line judge position in professional tennis globally — an estimated 400-500 role eliminations per major tournament when crew sizes are aggregated across the season. MLB's Automated Ball-Strike system completed full Triple-A deployment in 2023 and is in active negotiation for MLB implementation under the current collective bargaining framework. FIFA's Semi-Automated Offside Technology, using AI skeletal pose estimation to identify the 'relevant body part' in offside calculations, has been operational in Champions League since 2022-23 and produces offside calls in under 1 second versus 70+ seconds for human VAR review.
