VR system user experience design method driven by mental model

Abstract

The invention discloses a VR system user experience design method driven by a mental model, comprising the following steps: (1) firstly, user requirements are extracted, a designer deconstructs an element node of the VR experience design according to domain knowledge, and analyzes each level element in the experience design in detail in the form of a tree diagram; (2) the mental models of users and designers are constructed by card classification, and then the similarities of the two models are measured by path searching method to determine the specific difference factors; (3) according to their differences, the author analyzes the process and function of experience design by using the behavior affinity diagram in the macro mental model, analyzes the system function and the elements in theexperience design from the whole, and finally guides the designer to design the experience system that meets the user's needs. The method can minimize the cognitive difference between the designer and the user to the maximum extent, guide the designer to design an experience system which meets the requirement of the user, and improve the usability of the system.

Description

technical field [0001] The invention belongs to the field of computer-aided design, and in particular relates to a method for designing user experience of a VR system driven by a mental model. Background technique [0002] Virtual reality technology is a new computer simulation technology in the form of information display. It uses 3D graphics and equipment to provide users with a highly interactive experience, emphasizes real-time interaction, and creates an intuitive way for human-computer interaction. With the development of virtual reality technology, user-centered experience design has attracted more and more attention. In the existing technology, in the traditional VR experience design, the designer mainly uses his own ideas integrated with technology and creativity to design, and the user is a passive object to accept, so the designer may not be able to accurately grasp the user's perception of the VR reality experience. expected. And in a specific situation, the us...

AI Technical Summary

Problems solved by technology

Therefore, when people interact with a system or product, they often use their original cognitive experience and habits to make judgments. Due to the differences in experience and domain knowledge between the designer and the user, the cognitive difference between the two is relatively large, and in the design process There is a lack of comparison and matching measurement of its mental model, and the cognition difference between the designer and the user is large, which makes the final performance model of the system inconsistent with the user model, and the usability of the system is not high
