ACCESSORY IN-PLACE DETECTION SYSTEM

The present invention discloses a system for detecting proper positioning of an accessory, including an electronic device and a to-be-attached accessory. The electronic device includes a first attachment component, a magnetometer, and a processor. The to-be-attached accessory includes a second attachment component. The second attachment component is configured to be attached to the first attachment component, so that the to-be-attached accessory is fixed through attachment to the electronic device in a first orientation or a second orientation. The magnetometer is further configured to be triggered by a combined magnetic field of the first attachment component and the second attachment component to output the magnetic field intensity information when the to-be-attached accessory is fixed through attachment to the electronic device in the first orientation or the second orientation. The processor is configured to: output first indication information indicating that the to-be-attached accessory is fixed in position through attachment when the magnetic field intensity information meets a preset condition, and output second indication information indicating that the to-be-attached accessory is not fixed in position through attachment when the magnetic field intensity information does not meet the preset condition. Through the present invention, the consumable cost of the existing attachment detection solution can be effectively reduced.
