Problems solved by technology

[0003] However, in conventional methods, the accuracy of the cursor shown on the display device for user interaction by the user pointing at the target object may be affected by the swing or shake of the user's body or other factors.
If the sensitivity used to track the user's hand or controller is too high, the cursor may move frequently due to unsteady hands
On the other hand, if the sensitivity used to track the user's hand or controller is too low, the cursor may respond too slowly and be inaccurate most of the time

Abstract

Methods and systems are provided for showing a cursor for user interaction on a display device. In the method, a reference position to be initialized at the end of a ray projection emitted from the user side is determined. A target location is determined that moves with a body part of a user. The target position is different from the reference position. A modified position is determined based on the reference position and the target position. The reference position, the target position and the modified position are located on the same plane parallel to the user side. The modified location is different from the target location. The modified position is used as the current position of the cursor. The modified position represents the position of the end of the ray projection currently emitted from the user side. Thus, the cursor may be stabilized in augmented reality.

Description

technical field [0001] The present disclosure relates generally to interactions in extended reality (XR), and more particularly to methods and systems in XR showing a cursor at a current location on a display device for user interaction. Background technique [0002] Extended reality (XR) technologies, such as virtual reality (VR), augmented reality (augmented reality, AR) and mixed reality (mixed reality, MR), are popular nowadays for simulating sensation, perception and / or environment. The foregoing technology can be applied in various fields, such as gaming, military training, healthcare, remote work, and the like. In XR, a user can interact with one or more objects and / or the environment. In general, users may use their hands or controllers to change the field of view in the environment or to select objects of interest. [0003] However, in conventional methods, the accuracy of a cursor shown on a display device for user interaction by a user pointing at a target objec...
