Abstract
A head-mounted device, a wearing detection method, a wearing detection apparatus, and a medium are provided. The head-mounted device includes a GMR magnetic sensor and an IR sensor. The GMR magnetic sensor outputs a collected signal so that the MCU calculates a reference parameter indicating a position of the head-mounted device. The IR sensor outputs a collected signal so that the MCU makes determination based on the output signal. Only in a case that the reference parameter and the output signal meet the predetermined condition, it is determined that the head-mounted device is worn.
