Application of Virtual Reality Technology in the Design of Interactive Interfaces for Public Service Announcements

Abstract

With the development of technology, more and more public service announcements are being designed with interactive interfaces. There are many different ways to interact with interactive interfaces, and using appropriate design methods can expand the impact of PSAs. The study inco rporates image pre processing methods based on virtual reality, using the cvtColor grey scale function and median filtering method to process the images, an iterative approach to camera positioning method design, and subsequent performance testing of the r esearch algorithms. The test results showed that the peak signal to noise ratio of the research method was 13.390dB in the image pre processing process and 35.635dB on lightly shaded images; in the error test, the rotational mean error of the research meth od was approximately 4.2degrees at four reference points; and in the image plane reprojection test, 70% of the points of the research method almost coincided with the original point position. The method generated 1203 designs with 40 reference points. The experimental results show that the research method can effectively design interactive interfaces for PSAs in virtual reality environments, and can propose more design solutions, and has better performance in virtual reality environment positioning.
