In the present embodiment, as shown in fig. 1, the head mounted display device 10 may include: an apparatus body 11 and a storage device 12.
A magnetic field sensor 111 is arranged in the equipment body 11; a magnet is arranged in the accommodating device 12; when the apparatus body 11 is stored in the storage device 12, the magnetic field sensor 111 is aligned with the position of the magnet 121; the magnetic field sensor 111 is configured to control the head mounted display device 10 to maintain a standby state when detecting the magnetic field of the magnet 121.
Specifically, when the head-mounted display device 10 needs to be stored, the device body 11 is stored in the storage device 12, and at this time, the magnetic field sensor 111 provided in the device body 11 detects the magnetic field of the magnet 121 provided in the storage device 12, and the magnetic field sensor 111 controls the head-mounted display device 10 to be kept in a standby state. When the device body 11 is taken out of the storage device 12, the magnetic field sensor 111 disposed in the device body 11 cannot detect the magnetic field of the magnet 121, and thus, no control operation is performed on the head-mounted display device 10, so that the head-mounted display device 10 can normally operate.
For example, the magnetic field sensor 111 may be a hall sensor, which outputs a high level when it detects that the magnet 121 is close to the sensor and outputs a low level when it detects that the magnet 121 is far from the sensor. In the present embodiment, by using this principle, the hall sensor detects the magnetic field of the magnet 121 in the storage device 12, and the head mounted display device 10 is controlled to be kept in the standby state when stored in the storage device 12.
Further, as shown in fig. 2, in this embodiment, a proximity sensor 13 may be further disposed in the device body 11; the proximity sensor 13 is configured to detect a wearing state of the head mounted display device 10 when the magnetic field sensor 111 does not detect the magnetic field of the magnet 121.
Specifically, the proximity sensor 13 includes a light emitting unit 131 and a detecting unit 132; the light emitting unit 131 is configured to emit infrared light; the detection unit 132 is configured to detect the light intensity of infrared light reflected by an object to detect the wearing state of the head-mounted display device 10 according to the light intensity.
When the head-mounted display device 10 of the present embodiment is applied, when the magnetic field sensor 111 detects the magnetic field of the magnet 121, it is described that the device body 11 is stored in the storage device 12, and at this time, even if the head-mounted display device 10 is worn as a result of detection by the proximity sensor 13, the head-mounted display device 10 is controlled to be kept in a standby state. When the magnetic field sensor 111 does not detect the magnetic field of the magnet 121, it is described that the device body 11 is not stored in the storage device 12, and at this time, the wearing state of the head mounted display device 10 is detected by the proximity sensor 13.
Specifically, when the light intensity of the infrared light detected by the detection unit 132 of the proximity sensor 13 is greater than a first intensity threshold, it is determined that the head-mounted display device 10 is in a wearing state; when the light intensity of the infrared light detected by the detection unit 132 of the proximity sensor 13 is less than the second intensity threshold value, it is determined that the head-mounted display device 10 is not in the wearing state.
Furthermore, a reminder 14 connected with the magnetic field sensor 111 may be further disposed in the device body 11; the reminder device 14 is configured to emit a reminder signal when the magnetic field sensor 111 detects the magnetic field of the magnet 121. The reminding signal is used for reminding a user whether to place the equipment body 11 in place or not.
Illustratively, the reminding device 14 is a photodiode configured to emit a light reminding signal when the magnetic field sensor 111 detects the magnetic field of the magnet 121. When a user puts the equipment body 11 into the containing device 12, if the magnetic field sensor 111 is aligned with the magnet 121, the photodiode sends out a light ray reminding signal to remind the user that the equipment body 11 is put in place; otherwise, the user may slightly adjust the position of the device body 11 in the storage device 12 to align the magnetic field sensor 111 with the magnet 121 without emitting the light reminding signal. Or, when the user puts the device body 11 into the storage device 12, if the magnetic field sensor 111 is aligned with the magnet 121, the photodiode does not emit the light ray reminding signal; otherwise, the photodiode sends out a light reminding signal to remind the user that the device body 11 is not put in place, and the user can slightly adjust the position of the device body 11 in the storage device 12 to align the magnetic field sensor 111 with the magnet 121.
Illustratively, the reminder device 14 is a speaker configured to emit an audible reminder signal when the magnetic field sensor 111 detects the magnetic field of the magnet 121. When a user puts the equipment body 11 into the containing device 12, if the magnetic field sensor 111 is aligned with the magnet 121, the loudspeaker emits a sound reminding signal to remind the user that the equipment body 11 is put in place; otherwise, without emitting the audible alarm signal, the user may slightly adjust the position of the apparatus body 11 in the housing device 12 so as to align the magnetic field sensor 111 with the magnet 121. Alternatively, when the user puts the device body 11 into the storage device 12, if the magnetic field sensor 111 is aligned with the magnet 121, the speaker does not emit the sound reminding signal; otherwise, the speaker emits an audible alert signal to indicate to the user that the device body 11 is not in place, and the user may slightly adjust the position of the device body 11 in the storage device 12 to align the magnetic field sensor 111 with the magnet 121.
Illustratively, the reminder device 14 is a vibration motor configured to emit a vibration reminder signal when the magnetic field sensor 111 detects the magnetic field of the magnet 121. When a user puts the equipment body 11 into the containing device 12, if the magnetic field sensor 111 is aligned with the magnet 121, the vibration motor sends out a vibration reminding signal to remind the user that the equipment body 11 is put in place; otherwise, without giving the vibration alert signal, the user may slightly adjust the position of the apparatus body 11 in the housing device 12 so as to align the magnetic field sensor 111 with the magnet 121. Alternatively, when the user puts the device body 11 into the storage device 12, if the magnetic field sensor 111 is aligned with the magnet 121, the vibration motor does not send out the vibration reminding signal; otherwise, the vibration motor sends out a vibration reminding signal to remind the user that the device body 11 is not put in place, and the user can slightly adjust the position of the device body 11 in the storage device 12 to align the magnetic field sensor 111 with the magnet 121.

Therefore, whether the head-mounted display device 10 is stored in the storage device 12 can be accurately identified, and when the head-mounted display device 10 is detected to be stored in the storage device 12, the head-mounted display device 10 is controlled to be kept in a standby state, and power is saved.
