The Creation

To avoid flops, the control of the risks in product innovation and the reduction of the innovation cycles require valid and fast customer’s assessments. An Interactive Genetic algorithm is proposed for eliciting user’s perceptions concerning the shape of a product, in order to stimulate creativity and detecting design trends. Interactive users’ assessment tests are conducted on virtual products, for capturing and analyzing users’ responses. The IGA is interfaced with a CAD software (CATIA V5) and allows the creation in real time of a set of parameterized designs, which are presented iteratively by a graphical interface to the user for evaluation. After a description of the IGA, we present a study on the convergence of the IGA, according to the tuning parameters of the algorithm and the size of the design problem. An experiment was carried out with a set of 20 users on a particular product, table glasses. We describe the implementation of the perceptive tests and an analysis of the results. These results show how the IGA can be used to elicit user perception and detecting design trends.

Aided Design

To avoid failures in the marketplace, the control of the risks in product innovation and the reduction of the innovation cycles require fast and valid assessments from customers. An interactive genetic algorithm (IGA) is proposed for eliciting users' perceptions about the shape of a product, in order to stimulate creativity and to identify design trends. Interactive users' assessment tests are conducted on virtual products to capture and analyze users' responses. The IGA is interfaced with Computer Aided Design (CAD) software (CATIA V5) to create sets of parameterized designs in real time, which are presented iteratively by a graphical interface to the users for evaluation. After a description of the IGA, a study on the convergence of the IGA is presented. The convergence varies, according to the tuning parameters of the algorithm and the size of the design problem. An experiment was carried out with a set of 45 users on the application case, a dashboard, put forward by Renault. The implementation of the perceptive tests and the analysis of the results are described using hierarchical ascendant classification (HAC) and multivariate analysis. This paper shows how the results of tests using IGA can be used to elicit user perception and to detect design trends.

The Difference

Interactive Evolutionary Computation (IEC) is known as an effective method to create media contents suited to user’s preference and objectives. As one of the methods, we have applied Differential Evolution (DE) as evolutionary algorithm in IEC. This study investigated the efficacy of Interactive Differential Evolution (IDE) in comparison with Interactive Genetic Algorithm (IGA). Two listening experiments were conducted to investigate the efficacy: experiment 1 as a creating experiment with IDE and IGA, experiment 2 as a re-evaluating experiment. Target of the creation was warning sign sounds. Eighteen subjects participated in both of the experiments. The result of the experiment 1 showed that IDE overcame IGA, and significant increase of fitness was only observed in IDE. The result of the experiment 2, higher fitness value was observed in IDE, however, the difference between the two conditions was not significant. Parts of the results showed a possibility of IDE to create media contents.

And Performance

GenJam is an interactive genetic algorithm (GA) that models a human jazz improviser and performs regularly as the author's sideman on jazz gigs. GenJam learns to improvise full-chorus solos under the guidance of a human mentor and “trades fours” in real time with a human performer in “chase” choruses. In this article, the author first briefly describes GenJam's architecture, representations, genetic operators and performance characteristics. He then places GenJam in the context of a proposed taxonomy for GA-based music and art systems.

The Creation

Background: Innovation can result from progressive or significant changes to existing products leading to improvements in performance and user value. This is the type of innovation that is more easily perceived by the consumer, as it results in the creation of new products or the improvement of existing ones. Innovation in the Crafts Sector is a relevant topic to address market changes, and meet evolving consumer preferences. In this vein, artisans need to meet the calls for regularly investing in the design of new products and processes, with the purpose of achieving the sustainability of their business. Methods: This article addresses the existing calls for contextualizing the crafts sector and for fostering product innovation in this area, by investigating the barriers and problems faced by artisans, as well as by exploring existing experiences in overcoming them. The article builds on data collected in five European countries, under the scope of the Erasmus+ Project Craftsmanship+ “Fostering a New and Competitive Approach to Crafts and Semi Industrial high added-value sectors”1. Results and Conclusion: The aim is to analyze the importance of the crafts sector in a European context. This article contributes in a timely manner to the understanding of the crafts sector by paying attention to the obstacles that artisans face in order to ensure the sustainability of their business by introducing product innovation into their organization and/or market. This study offers a collection of innovation experiences in realities that are very significant for territorial identity, and thus aims to provide an incentive for further research.
