Matrixed Reality Technology Co., Ltd.

A head-mounted display device includes a head-mounted component, a display part, two cantilever arms, and a synchronous transmission mechanism, wherein the display part includes a housing and a positioning base; ends of the two cantilever arms in a first direction are respectively rotatably connected to two sides of the head-mounted component; the synchronous transmission mechanism includes a middle transmission component accommodated in the housing and two side transmission components at least partially accommodated in the housing, two ends of each side transmission component being respectively connected to the middle transmission component and one of the two cantilever arms; the positioning base is configured to be rotatably connected to the middle transmission component and prevent displacement of the middle transmission component relative to the housing; and the synchronous transmission mechanism is configured such that when one cantilever arm rotates, the synchronous transmission mechanism causes the other cantilever arm to rotate synchronously.

The present disclosure relates to method and apparatus for waking up a wearable device. The method includes: determining, based on a detected voice signal, whether the voice signal is from a wearer of the wearable device; determining, based on the voice signal, whether the voice signal belongs to a conversation between the wearer and the wearable device with a speech classification model; and waking up the wearable device when the voice signal is from the wearer and the voice signal belongs to the conversation between the wearer and the wearable device. The method and apparatus can wake up the wearable device during a normal interaction process between the wearer and the wearable device by using the method and apparatus, thereby realizing a natural wake-up process and improving the user experience of the wearable device.

A method and apparatus for spatial locating. The method includes: acquiring feature area information and a current image captured by a camera ( 102 ); searching the current image for a feature area of an interactive device based on the feature area information, to determine position information, the position information being used to indicate the position of the feature area in the current image ( 104 ); determining first pose information associated with the position and attitude of the feature area relative to the camera ( 106 ) based on the position information; calculating a re-projection error of the feature area in the current image ( 108 ) based on the feature area information and the first pose information; and if the re-projection error is less than or equal to a preset threshold, determining current pose information associated with the position and attitude of the interactive device currently in a global coordinate system ( 110 ) based on the first pose information.

The present disclosure discloses a method for refreshing screens of a head-mounted display device, a head-mounted display device, and a non-transient computer readable storage medium configured to store computer instructions. The specific implementation is as follows: from a first time point to a second time point, sending first data to both the first screen and the second screen, and writing the first data to the first screen, with the first screen configured to be in a black screen state, and the second screen configured to be in a bright screen state for at least part of the time; and from the second time point to a third time point, sending second data to both the first screen and the second screen, and writing the second data to the second screen, with the second screen configured to be in the black screen state, and the first screen configured to be in the bright screen state for at least part of the time to display the first data.

Embodiments of the present application provide a rotating shaft mechanism, a connection mechanism for glasses, and glasses. The rotating shaft mechanism includes: a first component having a first abutting portion; and a second component having a second abutting portion, the second component being rotatably connected to the first component, and the second component being rotatable relative to the first component and having a first position and a second position. The first component includes a cooperating portion, and when the second component is in the first position, the first abutting portion interacts with the second abutting portion to maintain the second component in the first position, and when the second component is in the second position, the cooperating portion interacts with the second abutting portion to maintain the second component in the second position; or the second component includes a cooperating portion, and when the second component is in the first position, the first abutting portion interacts with the second abutting portion to maintain the second component in the first position, and when the second component is in the second position, the first abutting portion interacts with the cooperating portion to maintain the second component in the second position.
