A method for unlocking a head-mounted display device based on gaze point information, comprising:
- acquiring gaze point information of a user who wears a locked head-mounted display device;
- generating unlocking information according to the gaze point information;
- performing a matching operation on the unlocking information and a pre-stored unlocking key;
- and
- unlocking the head-mounted display device when the unlocking information matches the unlocking key;
- wherein acquiring gaze point information of a user who wears a locked head-mounted display device comprises:
- acquiring eye feature information of the user through at least one information collector;
- and
- determining the gaze point information according to the eye feature information,
- wherein acquiring eye feature information of the user through at least one information collector comprises:
- acquiring successive a plurality of frames of the user's facial images or the user's eye images, and
- extracting eye feature points in each frame of the user's facial images or the user's eye images, and
- wherein determining the gaze point information according to the eye feature information comprises:
- determining gaze point track information according the changes in the eye feature points in the plurality of frames of the user's facial images or the user's eye images, wherein the gaze point information is configured as the gaze point track information.
A head-mounted display device, comprising:
- at least one information collector configured to acquire eye feature information of a user who wears a locked head-mounted display device;
- at least one processor, and
- a memory coupled to the at least one processor and configured to store a computer-executable instruction that, when executed, causes the at least one processor to perform:
- determining the gaze point information according to the eye feature information;
- generating unlocking information according to the gaze point information;
- performing a matching operation on the unlocking information and a pre-stored unlocking key;
- and
- unlocking the head-mounted display when the unlocking information matches the unlocking key,
- wherein the at least one information collector is configured to:
- acquire successive a plurality of frames of the user's facial images or the user's eye images, and
- extract eye feature points in each frame of the user's facial images or the user's eye images,
- wherein determining the gaze point information according to the eye feature information comprises:
- determining gaze point track information according to changes in the eye feature points in the plurality of frames of the user's facial images or the user's eye images, wherein the gaze point information is configured as the gaze point track information.
A method for unlocking a head-mounted display device based on gaze point information, comprising:
- presenting a reference object having at least one feature point, the reference object comprising one of a 3D virtual image presented in view field of a user who wears a locked head-mounted display device and an object presented on a display of the head-mounted display device;
- acquiring gaze point information of the user, the gaze point information comprising one of a feature point, feature point track information, and a feature point set of the reference object that the user is gazing;
- generating unlocking information according to the one of a feature point, feature point track information, and a feature point set of the reference object that the user is gazing;
- performing a matching operation on the unlocking information and a pre-stored unlocking key;
- and
- unlocking the head-mounted display device when the unlocking information matches the unlocking key.
