Abstract
In order to add the Kansei value of designers in product design, it is necessary to resolve the requirements consisting of Kansei value of designers, customer needs and limiting constraints without contradiction and reflect them in product design. In regard to this problem, the shape and layout creation system that considers the Mechanical Kansei has been developed. This system can create a discriminant function using TDNN (Time Delay Neural Network) based on the EEG(electroencephalogram) information obtained by the EEG measurement device EPOC+ and construct the layout of the shape using the fully stressed design method. On the other hand, it is important for the designer to validate the shape created based on Mechanical Kansei for the shape and layout creation system. Therefore, we will develop a shape evaluation system and confirm the designer’s satisfaction with the shape. For shape and layout evaluation, we propose an evaluation system using Mechanical Kansei and prospective expectation that can be obtained from the left prefrontal cortex and for Kansei value improvement. As a result, it showed that shape evaluation using Mechanical Kansei and positive expectation was possible, but the accuracy decreased depending on the requirements that the designer considered important.
