OffsideFence - Real-time offside feedback for football forwards

OffsideFence started from a simple absurd question: what if football players received real-time feedback before drifting offside? At first, it was just a joke about how far sports technology could go. But the more I looked into it, the more interesting the technical boundary became. Player detection, pitch mapping, tracking, and defensive-line estimation are all real computer-vision problems. The strange part is sending that signal directly back to the player through a wearable. So I built OffsideFence as a satirical sports-tech prototype. The goal is not to “fix” football, but to use an exaggerated product idea to ask a serious question: where should the game draw the line between analysis, assistance, and rule-breaking? The launch process also evolved along the way. It began as a funny concept, then turned into a product-style website, then a more complete prototype with pricing, modes, technical architecture, GitHub docs, and a short launch film. The final version tries to balance two things: it should look plausible enough to be taken seriously for a few seconds, then become absurd enough to make people question the direction of AI in sports.
