Solo alguien sin conocimientos técnicos puede creer que un sensor inalámbrico metido dentro de una pelota —que es pateada durante horas con una tasa de muestreo pésima— es capaz de detectar un pelo en su superficie en milisegundos, pero mágicamente inmune a la onda de presión si alguien la falla por un milímetro… todo transmitido por el aire en tiempo real a cientos de metros.
Es un acelerómetro. Capta vibraciones y cambios de presión de todo lo que esté cerca, hasta un insecto. Después la @FIFAcom decide qué pico cuenta como “toque”.
Y si el microchip marcó el “toque de cabeza” del croata… ¿por qué en la gráfica no aparece después el impacto clarísimo contra el defensor portugués?
Esto no es tecnología. Es un robo descarado. Uno de los más escandalosos de la historia del fútbol.
Y eso que han habido varios…

🇭🇷 Croatia got eliminated from the World Cup by a closed-source sensor.
FIFA says the Kinexon chip in the Trionda "proved" Matanović touched the ball. Absolute disgrace. What actually happened: they ran signal processing over 500Hz IMU data from a 14-gram sensor and isolated a supposed contact spike from thousands of noisy samples dominated by bladder harmonics, panel flex, spin wobble and stadium micro-tremors, then nullified one of the most dramatic World Cup equalizers in history via spectral analysis of what is essentially glorified noise.
Oh, and it gets better. They moved the chip this year. Back in 2022, it used to hang suspended in the center of the ball. Now it's glued into the sidewall of ONE panel, with counterweights stuffed into the other three so the ball doesn't fly like a shopping cart. So sensitivity now depends on which side of the ball the "contact" happens relative to the sensor. Totally fine basis for ending a nation's tournament.
An IMU measures acceleration. Somewhere in a proprietary pipeline, a threshold decides which acceleration counts as "touch." That threshold is unpublished. The false positive rate is unpublished. The calibration data is unpublished. The patents are literally still in their secrecy window. And FIFA owns the raw data, so nobody can independently audit the trace that ended Modrić's last World Cup.
And we're all supposed to accept a "heartbeat graphic" on the broadcast as if that settles anything.
Since we sadly all know you won't ever admit your crimes or remove this technology for good, at least open source the detection pipeline, @FIFAcom!
Publish the thresholds, the error rates, the raw IMU trace from last night. If the tech is right, transparency costs nothing, right?
🚨🗣️ Wayne Rooney: "Daylight robbery man, this is unacceptable. How is that offside when the ball clearly hit the head of Veiga! Saw Modric laugh and I said yeah the ref is a joke."
"Ronaldo and Roberto Martinez should know they don't deserve this win."
