Magneto-Track Football: 3D Football tracking with Disney Research
Referees may soon have a new way of determining whether a football team has scored a touchdown or gotten a first down. Dr. Ricketts and his colleagues, in collaboration with Disney Research, have developed a system that can track a football in three-dimensional space using low-frequency magnetic fields.
