Abstract: The embodiments of the disclosure provide a method for managing tracking devices, a device manager, and a computer readable storage medium. The method includes: receiving a local map corresponding to each of a plurality of tracking devices and accordingly generating a shared map; obtaining a pose ambiguity status corresponding to each of the tracking devices; determining at least one first specific device among the tracking devices based on the pose ambiguity status corresponding to each of the tracking devices; and disabling at least one function of the at least one first specific device.

Abstract: The embodiments of the disclosure provide a method for adjusting a virtual object, a host, and a computer readable storage medium. The method includes: obtaining a first field of view (FOV) of a virtual world; obtaining a second FOV of a camera, wherein a first physical object locates within the second FOV of the camera; determining a FOV ratio based on the first FOV and the second FOV; determining a first position of a first virtual object in the virtual world relative to a reference object in the virtual world, wherein the first virtual object corresponds to the first physical object; determining a second position of the first virtual object in the virtual world based on the first position and the FOV ratio; and showing the first virtual object at the second position in the virtual world.

Abstract: This invention relates to a method for making high metallic luster, high impedance on flexible polymer based material, in which a lustrous layer is coated on the first surface of a flexible polymer based material by means of wet coating and a color protection layer is further coated on the lustrous layer or the second surface of the flexible polymer based material. In this manner, metal-like feeling and luster is enhanced by the lustrous layer such that the flexible polymer based material has low metal shielding effect or light-shield capability. In addition, the transmittance of light and electromagnetic wave in demanded range become better so that the interference on the quality of transmission and receiving can be avoided.
