Research On Depth Conflict Reduction Of Graphical Interactive Components In Virtual Scenes

The development of virtual scene requires a more natural interaction paradigm to meet the needs of users.The graphical paradigm can be an effective supplement to the natural paradigm,but there is little research on the use of graphical paradigm in virtual space.In this paper,a SOMRM interaction paradigm is proposed,which is divided into Situation,Object,Menu,Reminder and Multimodel Interaction.By combing the composition,definition and use scenarios of each part of the interaction paradigm,designers can better comb the main content of virtual metaphor expression,and help researchers confirm the location of deep conflict in virtual scenes.In the application of virtual scene,the graphical paradigm still has the problem of depth conflict with the main body of the scene,which includes three types: non stereo conflict,near far conflict and map conflict.Non stereo conflict refers to the fact that the depth cues of UI parallax indicating graphical components in the virtual scene are farther than those in the scene.Scholars have basically solved this problem through stereo redirection.Near far conflict refers to the problem that the user's perspective is not focused on switching between components and scenes and produces fatigue.Map conflict refers to the problem that the edge of the graphical component overlaps the main scene.Near far conflict and map conflict mainly occur in graphical components.This paper studies the way of user perception depth in the scene.Based on the assumption of graphical interaction paradigm,depth conflicts can be alleviated by adjusting the distance between components and users and adding halo blur to graphical interaction components.By combing the user's interaction behavior in the virtual scene,the relationship between different interaction intention and operations is established to help improve the interaction task design in the experiment.In the experiment,we build virtual reality finding different and augmented reality Tetris virtual interactive scenes,and study two methods to alleviate the depth conflict in virtual scene,which are aperture blur and component distance change,and measure them by accuracy,ease of use and other dimensions.In the virtual scene,the subjects interact with each other,such as viewing,grabbing,sliding,etc.,and the staff and the system record the completion time,deviation information and other data,and through interviews and scales,data-based subjective experience.The results show that adding halo blur is a better way to alleviate the depth conflict in virtual scene interaction.
