A content transmission method is provided. The method may include: A first device determines that a distance between the first device and a second device is less than a distance threshold. The first device provides a user with a prompt that content transmission can be performed between the first device and the second device. The first device recognizes a gesture operation performed by the user on the first device, and determines transmission content and a transmission direction of the transmission content between the first device and the second device based on the recognized gesture operation. The first device receives the transmission content from the second device or sends the transmission content to the second device based on the determined transmission direction.

An image display method includes: obtaining a homography matrix between a first target plane and a second target plane according to the first target plane and the second target plane; obtaining a target displacement according to the homography matrix and an attitude; obtaining a target pose according to the target displacement, the target pose including a position and an attitude of a camera coordinate system of a current frame image in a world coordinate system; and displaying an AR image according to the target pose.

An electronic apparatus includes: control means for performing control to record, in recording means, characteristic data on a line-of-sight; authentication means for authenticating a user; and detection means for detecting, in a case where characteristic data on a line-of-sight of the authenticated user is recorded in the recording means, a line-of-sight of the user by using the recorded characteristic data on the line-of-sight.

A method and handheld device for remotely interacting with a second device. The method and apparatus identify the second device from a plurality of devices based on the gestures of the user. As the user gestures, movement sensors sensing the motion of these gestures can generate signals that can be processed by rule-based and/or learning based methods. The result of processing these signals can be used to identify the second device. In order to improve performance, the user can be prompted to confirm the identified second device is the device the user wants to remotely control. The results of processing these signals can also be used so that the user can remotely interact with the second device.

A tracking method, for tracking an object based on a computer vision, includes following steps. A series of images is captured by a tracking camera. A first position of a trackable device is tracked within the images. An object is recognized around the first position in the images. In response to the object being recognized, a second position of the object is tracked in the images.

An electronic device includes a transceiver and a processor. The processor is operably connected to the transceiver. The processor is configured to transmit, via the transceiver, radar signals for activity recognition. The processor is also configured to identify a first set of features and a second set of features from received reflections of the radar signals, the first set of features indicating whether an activity is detected based on power of the received reflections. Based on the first set of features indicating that the activity is detected, the processor is configured to compare one or more of the second set of features to respective thresholds to determine whether a condition is satisfied. After a determination that the condition is satisfied, the processor is configured to perform an action based on a cropped portion of the second set of features.

The method includes: displaying first graphical elements associated with first plurality of output modalities within an XR environment; while displaying the first graphical elements, detecting movement of a physical object; and in response to detecting the movement of the physical object: in accordance with a determination that the movement of the physical object causes the physical object to breach a distance threshold relative to a first graphical element among the first graphical elements, selecting a first output modality associated with the first graphical element as a current output modality for the physical object; and in accordance with a determination that the movement of the physical object causes the physical to breach the distance threshold relative to a second graphical element among the first graphical elements, selecting a second output modality associated with the second graphical element as the current output modality for the physical object.
