Abstract: A cross-platform interaction method of VR and AR, AR device, AR server, VR device and VR server are disclosed. The method is applied to the AR server and comprises: acquiring first cross-platform interaction data corresponding to an AR client (S101); generating a first XML data interaction file corresponding to the first cross-platform interaction data (S102); and sending the first XML data interaction file to the VR server corresponding to a target VR client to enable the target VR client to perform a corresponding cooperative operation according to the first cross-platform interaction data (S103). The present disclosure uses the cross-platform characteristics of XML can realize the data interconnection between two platforms in the form of a lightweight database, improve the synchronization efficiency of cross-platform interaction data, realize standardized management of data from different platforms, and reduce resources used in the collaborative integration development of different VR and AR programs.

Abstract: A near-eye display device and an eye tracking system for the near-eye display device are provided. The eye tracking system includes a processor, a control analysis device, an LED illuminating device, a DMD display device and an IR camera. The processor outputs a video signal corresponding to a video displayed on the near-eye display device to the control analysis device. The control analysis device generates an LED synchronization signal and a corresponding subfield display signal. The LED illuminating device drives an LED to emit light, and transmits the light emitted from the LED into the DMD display device. The DMD display device reflects the light into a lens to form an image, and projects the image onto an eye. The IR camera captures an eye image. The control analysis device acquires the eye image and analyzes the eye image to obtain gaze point information.
