In general, computer-aided design support systems have got an approach of traditional artificial intelligence, which statistically analyzes data such as the behavior of designer, to extract formal design behavior. This approach, however, can neither deal with continuous change of fashion nor reflect personal taste well, as it just depends on large amount of collected data. To overcome this sort of problem interactive genetic algorithm (IGA) has been recently proposed, as a new trend of evolutionary computation. IGA uses human's response as fitness value when the fitness function cannot be explicitly defined. This enables IGA to be applied to artistic domains, and we propose a fashion design aid system using it. Unlike the previous works that attempt to model the dress design by several spline curves, the proposed system is based on a new encoding scheme that practically describes a dress with three parts: body and neck, sleeve, and skirt. By incorporating the domain-specific knowledge into the genotype, we could develop a more realistic design aid system for women's dress. We have implemented the system with OpenGL and VRML to enhance the system interface. The experiments with several human subjects show that the IGA approach to dress design aid system is promising.

This paper presents an interactive music composition system as one example of human centered systems that are defined as subjective systems in which human judgement, evaluation, recognition and emotion play central roles. The present music composition system reflects user's evaluation of music and employs interactive genetic algorithm. One musical work is assumed to be expressed by one chromosome containing information on a melody part and backing parts through 4 bars. The composition procedures are as follows. (1) Two hundred chromosomes are generated based on general music theory. (2) A user listens to 20 musical works chosen from 200 works and performs three types of evaluations such as total evaluation, partial evaluation, and the choice of the best work. (3) The system performs the GA operations to 200 chromosomes reflecting these evaluations. Procedures (2) and (3) are repeated until a musical work reflecting user's evaluation is obtained. From the results of the evaluation experiments to confirm the validity of the system, it is found that the present system composes music reflecting user's evaluation well and is one example of human centered systems.

This paper aims at the construction of the interactive music composition system which generates 16-bars music reflecting users feeling and subjectivity for music. The interactive genetic algorithm is introduced to this system. This paper tries to reduce users load in the evaluation of musical works. To this end, this paper uses fitness evaluations based on music theory by which presented music works are chosen. Furthermore, visual interface is designed by which users can follow the presented musical works. From the experimental results to confirm the validity of the present system, it is found that the subjects evaluation values of composed musical works becomes higher with the progress of generations. Furthermore, the subjects answer that the present system is better than the previous system from the viewpoint of understanding musical works visually.
