Evaluation Criteria for Texture of Sportswear in 3D Wearing Simulation

Abstract

To investigate the evaluation criteria of the surface texture of sports clothing in 3D wearing simulation compared to actual clothing, a comparison was conducted on the similarity and difference between the simulated and the actual clothing images and those impression. We also tracked the eye movements of the evaluators during impression evaluation using a gaze-tracking device to investigate the parts of the garments they paid attention to. We prepared eight sportswear pieces with different materials and colors and created simulated and actual images worn on a mannequin. The evaluators were 20 university students in their twenties. As a result, the evaluators gazed at the garment's chest, hip, and leg curved parts in the simulated and actual image. There were less significant differences in the overall impression of a garment, such as gaudiness and elegance, between the simulated and the actual images. However, the simulated images of bright-colored or glossy fabrics tended to be evaluated as thicker and heavier than actual ones. The impression of smoothness also tended to differ in both. For dark and mat fabrics, there was no significant difference between the simulated and actual images. When evaluating the texture of sportswear in 3D wearing simulation, the evaluation items that cause differences from the actual image are "thickness," "weight," "smoothness," and "glossiness." Those are considered as the evaluation points of the difference between the simulated and the actual clothing. In electronic commerce, simulation images can convey the overall impression of a garment. Simulation images can be used more effectively as product images considering the evaluation points of this research result.
