Abstract: A virtual trackpad and method for using the same are disclosed. In some embodiments, the method comprises: projecting a virtual trackpad on one hand of a user using hand tracking position data from an extend reality (XR) device; detecting, via hand tracking, movements of one or more fingers as the one or more fingers are being moved across the virtual trackpad projected on the one hand; and controlling a user interface (UI) being displayed on a display by the XR device based on the movements of the one or more fingers.

Abstract: Methods and apparatuses for controlling a user interface with a wearable device, such as a smart watch, are disclosed. In some embodiments, the method includes detecting, by an extend reality (XR) device, a wearable device, communicably connecting the XR device to the wearable device, and manipulating a user interface in a virtual environment displayed on a display in the XR device with the wearable device.

Abstract: A method and apparatus for controlling objects being displayed in a user interface (UI) in a virtual environment generated by an XR device using a wearable device are described.

Abstract: Methods and apparatuses for performing multi-window control in a user interface are disclosed. In some embodiments, the method includes displaying the user interface in a display of an extend reality (XR) device, where the user interface includes a graphical user interface (GUI) element and a number of objects. The method can also include detecting selection of the GUI element in the UI; moving a set of objects being displayed on the display into a window on the display; detecting a selection of one or more of objects in the set of objects by tracking movement of a user; and displaying selected objects of the one or more objects in front of a user.

Abstract: A mobile communications network and data delivery method in a mobile communications network is provided that can implement connectionless transfer in the mobile communications network, and obviate the need for sending a call control signal for data delivery. An IP address is assigned to each of the nodes of the mobile communications network including routing nodes (a gate node and repeater node, for example) and edge nodes and to each mobile station. A routing node, receiving data including the IP address of a mobile station, carries out routing of the data in accordance with routing information. The edge node that receives the data routed by the routing node, transmits the data to the mobile station corresponding to the IP address of the mobile station added to the data. The IP addresses are also applicable to delivering data to users of the same group, or carrying out control like handover.
