Genius Sports designed this caller semiautomated offside tech, internally known arsenic “Dragon.” The antecedently utilized VAR strategy is notorious for causing controversies, per Wired. It would pb to “extensive delays and quality process errors” and “concerns astir the precision of in-game calls.” Genius Sports has worked with NBA hoops for years connected “optical tracking and data-based work.”

For EPL, Genius volition start by positioning 28 iPhones successful each stadium. Genius mentioned that it mightiness adhd much iPhones astatine prime stadiums passim the year. Wired says these volition mostly beryllium iPhone 14 models, but The Verge claims Matt Fleckenstein, Genius’s CPO, told them successful an interrogation that iPhone 15 Pros volition beryllium utilized to get the occupation done.
