Embodiment Construction

[0025] refer to figure 1 Shown is a schematic flow chart of a virtual reality visual interaction method, the present invention adopts the following technical solutions:

[0026] A visual interaction method, characterized in that, comprising the following steps:

[0027] Step 1. Identify the user's eyeball picture, and locate the center of the pupil in the picture through picture preprocessing;

[0028] Step 2. Calibration. Several bright spots (1-9 can be selected) appear in sequence on the screen. When each point appears, the user focuses on this point, and the system takes a picture of the eyeball at this time. Establish a corresponding relationship between the position coordinates of each point and the pupil position picture when observing the point, so as to realize the real-time display of the pupil's gaze position on the screen and realize visual tracking;

[0029] Step 3: Identify whether the mapped position of the pupil on the screen overlaps with the position of the...

Abstract

The invention discloses a visual interaction method, system and device. The method comprises following steps: step 1. identifying an image of a user eyeball and locating the central position of pupil in the image by image preprocessing; step 2. calibrating: several bright spots appear in turn on a screen, and a user watches each bright spots as it appears, a system photographing the eyeball at the moment; establishing corresponding relationship between the position coordinate of each bright spots and the image of pupil position when the user watches the bright spots so as to achieve real-time display of the staring position of the pupil on the screen and achieve visual tracking; step 3. identifying whether the mapping position of the pupil on the screen and the position of the interactive icon in the screen coincide, and then determining whether to activate the icon. The technical effects that can be achieved by the present invention are as follows: the user experience in the VR experience can be improved, the response speed of the computer can be improved, the UI icon can be selected by user sight, and the screen texture of the interaction interface can be improved.

Description

technical field [0001] The invention belongs to the technical field of virtual reality methods, and in particular relates to a visual interaction method, system and equipment. Background technique [0002] In the virtual reality (VR) experience in the prior art, part of the visual tracking technology is used. When the user's gaze is fixed on a certain place on the interactive interface, a similar mark like a mouse cursor will be generated to facilitate the interactive manipulation of the user equipment. Select the icon. However, because the change of VR images will generate a large amount of data calculation, the computer processing time is too long, and during visual interaction, the mouse cursor image generated in the UI (ie, interactive interface) screen is unstable and the screen shakes, reducing the user experience. experience effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a virtual reality visual...
