Background

At the heart of manila, philippine, NIKE constructed the first runway "unlimitedstable" with large LEDs in the world, which was prototyped with the NIKE classic running shoe Lunar Epic, the entire playground was a shoe-type figure, and a running screen consisting of ten million LEDs was set up along the 200 m-length runway. Athletes must have sensors on their own nike shoes. When the running program is started, a virtual opponent appears on the electronic display screen, which is at a speed comparable to you and occasionally overshoots.
