A Product Shape Congruity Measure via Entropy in Shape Scale Space

Product shape is one of the factors that trigger preference decisions of customers. Congruity of shape elements and deformation of shape from the prototype are two factors that are found to influence aesthetic response, hence preference. We propose a measure to indirectly quantify congruity of different parts of the shape and the degree to which the parts deviate from a sphere, i.e. our choice of the prototype, without explicitly defining parts and their relations. The basic signals and systems concept that we use is the entropy. Our measure attains its lowest value for a volume enclosed by a sphere. On one hand, deformations from the prototype cause an increase in the measure. On the other hand, as deformations create congruent parts, our measure decreases due to the attained harmony. Our prelimi


The influence of product appearance on perceived product quality in reference to washing machines
Veyisoğlu, Ahmet Burak; Hasdoğan, Gülay Fatma; Department of Industrial Design (2010)
Product quality is regarded as one of the most important factors that consumers consider while purchasing products. However, contrary to objective quality, perceived product quality includes consumer's judgment about the overall superiority or excellence of a product. This study mainly concentrates on the relationship between product appearance and perceived product quality especially for durable goods. The definitions of product quality and perceived product quality are reviewed to explain different dimens...
The influence of visual appeal on perceived usability
Yılmaz, Ebru Cansızoğlu; Ünlü, Canan Emine; Department of Industrial Design (2006)
Usability is regarded as one of the most important factors that consumers consider while purchasing products, however it is difficult to judge usability unless the user actually uses the product. Perceived usability is influential for consumers when identifying a product as usable and purchasing it. This study concentrates on the relationship between visual appeal and perceived usability especially for consumer products. The influence of visual appeal on perceived usability for consumer products is scrutini...
Determination of factors that cause shopping hesitation
Külter Demirgüneş, Banu (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2018-4)
This study aims to provide general understanding of different set of factors that cause hesitation in buying electronic products. The study proposes seven cosntructs that predict shopping hesitation. The research model offers that consumer traits of innovativeness, risk averseness, brand consciousness, price/value consciousness, confused by over choice and contextual factors as time pressure and negative past experience cause shopping hesitation. The study tries to answer if these seven factors pertain...
A fuzzy linguistic decision model approach for selecting the optimum promotion mix for digital products with genetic algorithms
Gün, Mustafa Murat; İşler, Veysi; Department of Computer Engineering (2010)
Promotion is one of the four major marketing elements of the marketing mix (others are product, price and place) in implementing marketing strategy. Promotion is dealing with the ways a company communicates with its customers to persuade them to buy the product. Promotion mix covers all the different ways a company choose to communicate with its customers such as advertising, personnel selling, PR, sales promotion and others. Selecting the optimal blend of the promotion mix is a tough and critical issue for...
