Problems solved by technology

[0004] When realizing virtual integration, it is necessary to track the position information of the user's head. In the prior art, the motion parameters of the user's head are usually collected through a motion sensor to calculate the position information of the user's head. Since the user's head Internal position tracking is a long-term process. There will be certain errors in the motion parameters collected by the motion parameter sensor. The long-term accumulation of errors will lead to inaccurate tracking results.

Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0053] In the embodiment of this application, when the user wears the head-mounted device, the motion parameters when the user's head moves, and the environmental space information are obtained, so as to obtain the position information after the user's head moves by using the environmental space information and motion parameters . Compared with the way in the prior art, which only uses motion parameters to calculate the user's position information, the embodiment of the present appl...

Abstract

The embodiment of the invention provides an information processing method and device, which are applied to a head-wearing device. The information processing method comprising the following steps: when a user wears the head-wearing device, acquiring motion parameters when the user's head moves; acquiring environmental spatial information; adopting the motion parameters and the environmental spatial information to acquire position information after the user's head moves. According to the information processing method and device provided by the embodiment of the invention, the accuracy of acquiring the user's head position information is improved, so that the user's head tracking results are more accurate.

Description

technical field [0001] The present application relates to the field of electronic technology, and more specifically relates to an information processing method and device. Background technique [0002] Head-mounted smart devices refer to smart devices developed by using wearable technology to intelligently design head-mounted devices, such as smart glasses. [0003] When the user wears the head-mounted smart device and watches the display content output by the head-mounted device, the visual imaging space of the display content viewed by the user is different from the display interface of the display unit. From the perspective of the user, the display content viewed by the user is the virtual content, and the virtual content is superimposed on the real environment viewed by the user, so that the combination of virtual and real can be realized. [0004] When realizing virtual integration, it is necessary to track the position information of the user's head. In the prior art,...
