Perceptual Quantitative Decision Making and Evaluation of Product Stylable Topology Design

Abstract

Modeling is the primary point to conveying product characteristics. Accurately capturing the image needs of users for modeling is an important way to effectively improve product design efficiency. Quantitative theory type I is a method to solve the internal law between the user’s target image and the product modeling characteristics by building a mathematical model. Aiming at the problems of abundant product modeling design elements, diversified combination methods, and high design cost due to the subjective ambiguity of user images, a topological design method of product modeling based on quantification theory I is proposed. This method uses the semantic difference method and statistical method to obtain the quantitative data of perceptual semantic features of product modeling to represent the explicit and implicit needs of users. Based on the topological transformation, the topological analysis and modeling of the two types of requirements are carried out. The mapping model of product modeling features and style images is constructed using quantitative theory type I, and the topologic value of each modeling design element is calculated. The above method can effectively solve the mapping problem between product modeling features and style images. On this basis, this research provides a decision-making basis for product modeling design. Using a wine jug as a product exemplar for this research, the scheme design and evaluation are carried out to verify the effectiveness and feasibility of the product modeling topological design method.

Older Users Acceptance of Smart Products: An Extension of the Technology Acceptance Model

“…For example, Muslim et al [14] proposed the use of Web service recommender systems to analyze user experience data of available items/smart products to obtain user requirements. Wang et al [15] refined users' perceptual needs based on the three dimensions of smart products, user perception, and behavioral prediction to provide a guiding path for improving the efficiency of product design. requirements importance assessment, specifically referring to the use of assessment methods to identify the satisfaction of needs and to form a prioritization of needs based on the results.…”

Design Research on the Production Process of Chinese Dangyangyu Twisted Porcelain Based on Extension Semantics Orientation

“…Design is admissible to scientific inquiry because we can study how the relevant information can and should be processed . Combining topologically related theories to study contradictory problems that arise in the design process can provide a more comprehensive description of certain properties, the number of features, the range and the degree of things, and can then provide solutions to contradictory problems in design through formal transformations and algorithms (Wang Y et al,2022).From the dimensions of production craft and artistic characteristics, this paper has explored the cultural connotations of twisted porcelain with the combination of extension theory and performed an analysis of extension semantics so as to develop an important method for promoting the innovation and development of intangible culture of twisted porcelain and provide a reference for the innovation and development of contemporary ceramics.…”

Multi-Objective Image Optimization of Product Appearance Based on Improved NSGA-Ⅱ

“…The manifestation of this mapping relationship can be divided into linear and nonlinear objective functions. Multiple regression analysis [15], Quantification Theory Type I [16], and other techniques are often used to build linear models. All these ways are used to extract the most important form elements by expressing the relationship between the product form elements and the perceptual imagery through the coefficients of the independent variables [17].…”
