Abstract

An electronic apparatus includes a controller, a display device coupled to the controller, and a detector coupled to the controller. The display device displays virtual environmental images. The detector detects a spatial parameter of a local space of the electronic apparatus in which the electronic apparatus is located. The controller receives the spatial parameter and controls the display device based on the spatial parameter.

First claim

What is claimed is:

1. An electronic apparatus comprising:
a controller;
a display device coupled to the controller, the display device displaying virtual environment images; and
a detector coupled to the controller, the detector detecting a spatial parameter of a local space of the electronic apparatus in which the electronic apparatus is located,
wherein the controller:
receives the spatial parameter;
determines, based on the spatial parameter, that the electronic apparatus has moved from a first space having a first spatial parameter to a second space having a second spatial parameter; and
controls the display device to display a virtual environment image that matches the first spatial parameter.

2. The electronic apparatus according to claim 1 , wherein in response to a space volume of the first space being smaller than a space volume of the second space, the controller controls the display device to inform a user of the electronic apparatus that a portion of the second space that exceeds the virtual environment image is unreachable.

3. The electronic apparatus according to claim 1 , wherein in response to a space volume of the first space being bigger than a space volume of the second space, the controller controls the display device to not display a portion of the virtual environment image that exceeds the second space.

4. The electronic apparatus according to claim 1 , wherein the detector includes an ultrasonic sensor, the ultrasonic sensor sending an ultrasonic signal and detecting the spatial parameter based on a reflected ultrasonic signal.

5. The electronic apparatus according to claim 4 , wherein in response to the local space being a non-closed space determined based on a value of the reflected ultrasonic signal along a direction, the controller controls the display device to display the virtual environment image within a threshold distance along the direction.

6. The electronic apparatus according to claim 4 , wherein:
the detector further comprises an infrared sensor, the infrared sensor collecting a biological infrared signal, and
the controller controls the display device to display the virtual environment image that matches the biological infrared signal.

7. The electronic apparatus according to claim 1 , further comprising a maintaining device, wherein the display device, the detector, and the controller are mounted on the maintaining device and the maintaining device maintains a relative position between a user of the electronic apparatus and the electronic apparatus.

8. A displaying method comprising:
detecting a spatial parameter of a local space of an electronic apparatus in which the electronic device is located; and
receiving the spatial parameter and controlling a display device of the electronic device based on the spatial parameter, including:
determining, based on the spatial parameter, whether the local space of the electronic apparatus has changed, including:
determining that the electronic apparatus has moved from a first space having a first spatial parameter to a second space having a second spatial parameter; and

controlling the display device based on a result of the determination, including:
controlling the display device to display a virtual environment image that matches the first spatial parameter.

9. The method according to claim 8 , wherein controlling the display device based on the result of the determination further includes, in response to a space volume of the first space being smaller than a space volume of the second space, controlling the display device to inform a user of the electronic apparatus that a portion of the second space that exceeds the virtual environment image is unreachable.

10. The method according to claim 8 , wherein controlling the display device based on the result of the determination further includes, in response to a space volume of the first space being bigger than a space volume of the second space, controlling the display device to not display a portion of the virtual environment image that exceeds the second space.
