Embodiment Construction

[0016] In the following description, more specific details are set forth in order to provide a full understanding of the present invention. However, the present invention can be implemented in other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0017] The following describes the specific implementation of the technical solution of the present invention in conjunction with the accompanying drawings.

[0018] In VR, what the user sees is to simulate various objects in the real space. As the user moves, the relative relationship between the user and the object changes accordingly, and the appearance characteristics of the object viewed by the user change accordingly, which makes the user feel Real and natural experience, so as to realize the effect of simulating reality. ...

Abstract

The invention provides an eye movement analysis method based on a sight line and collision body intersection point in VR (virtual reality). The method comprises the following steps of building a three-dimensional model; guiding the three-dimensional model into a physical engine; setting a collision body for the three-dimensional model; tracking the sight line of a user; determining the interaction point according to the sight line and the collision body, wherein an object comprised by the collision body is an object seen by the user; recording data. The method provided by the invention is mainly applied to VR; the eye movement technology is combined; the interested region is recorded in real time; the object in the VR scene is subjected to 360-degree panorama analysis; the detection sight angle and range are large.

Description

technical field [0001] The invention belongs to the field of VR, and in particular relates to an eye movement analysis method in VR based on the intersection of a line of sight and a colliding body. Background technique [0002] As people's requirements for interactive experience continue to increase, virtual reality (Virtual Reality, VR) applications have achieved rapid development. Vision-based VR systems have gradually become the mainstream of applications, such as VR games and VR medical equipment. In virtual reality systems and applications, users interact with virtual objects, and VR scene settings that are accurate and in line with market consumption requirements have become the focus of competition among software manufacturers. How VR software manufacturers determine user needs is the key to this competition. [0003] VR software manufacturers generally use 3D modeling tools to model and import the 3D model into the physical engine. Existing detection techniques ca...
