  • Review of Models and Frameworks for Set-Based Design   Order a copy of this article
    by Mayara Silvestre De Oliveira, Fernando Forcellini, Jaime Lozano, Jader Riso Barbosa Jr. 
    Abstract: This paper aims to investigate the state-of-the-art in models and frameworks for set-based design and identify the main gaps and contributions in the literature. As a result, 121 models were analysed. Most models are quantitative, computational, engineering design-oriented, and focus on early stages. Although the narrowing down process plays a central role in the set-based design, very little is addressed regarding its management processes. No model was found describing the inputs and outputs of the set-based design and the narrowing down process simultaneously. Thus, knowledge is dispersed and focused on specific parts. The relevance of this study relies on providing a comprehensive investigation of the state-of-the-art, identifying opportunities to advance in this study field, and providing recommendations for future works seeking to support the development of new methods for implementing and managing set-based design, enabling and encouraging its adoption.

  • A Formal Consideration of User Tactics During Product Evaluation in Early-Stage Product Development   Order a copy of this article
    by Trent Owens, Christopher Mattson, Carl Sorensen, Michael Anderson 
    Abstract: Frequent and effective design evaluation is foundational to the success of any product development effort. Products used, installed, or otherwise handled by humans would benefit from an evaluation of the product while formally considering both the physical embodiment of the technology, termed technology, and the steps a user should take to use that technology, termed tactics. Formal and simultaneous evaluations of both technology and tactics are not widespread in the product design literature. Although informal evaluation methods have advantages, formal methods are also known to be effective. In this paper we propose a formal method for evaluating tactics and technology simultaneously. Unlike the published literature, this evaluation involves explicitly defined tactics in the form of a written description of the actor, environment, and series of steps. It also involves the use of stage-appropriate, explicitly defined tactics-dependent criteria, which include criteria from a broad range of impact categories, such as impacts on the user, environment, project, and technology.
    Keywords: Conceptual Design Evaluation; Tactics Evaluation; Human-Centered Design; Human Factors.

    by Jinrong Li  
    Abstract: Starting from effectively improving the evaluation accuracy and efficiency of the quality of the interactive interface of intelligent products, this paper proposes a method for evaluating the quality of the interactive interface of intelligent products based on Bayesian classification.

  • Color offset compensation method of product packaging image based on color difference interpolation   Order a copy of this article
    by Zhao Lan 
    Abstract: In order to effectively improve the accuracy of image color offset compensation and reduce the compensation time, a color offset compensation method based on color difference interpolation is proposed in this paper. Based on bilinear chromatic aberration interpolation algorithm, the full resolution chromatic aberration signal of image is estimated preliminarily. After image filtering, the basic color data and gray balance data of the image are compared to obtain the color offset. Taking color block as the minimum unit of deviation compensation, the average value of extended color level interpolation was added to the single color level of the calibrated image to complete color offset compensation. Experimental results show that the maximum compensation time of the proposed method is only 29.6s, and the maximum MSE value of the compensation result is only 0.179, indicating that the proposed method has higher compensation accuracy.
