Virtual reality-based collaborative design method for designing customized garment for disabled people with scoliosis

Abstract

Purpose The purpose of this paper is to present a new collaborative design-based method for designing customized garments, aimed at the physically disabled people with scoliosis. Design/methodology/approach The proposed method is based on the virtual human model created using a 3D body scanner, permitting to simulate the consumer’s morphological shape with atypical physical deformations. Next, customized 2D and 3D virtual garment prototyping tools will be used to create products through interactions between the consumer, designer and pattern maker. The general principle of the proposed design method is based on the following sequence: design-display-evaluation-adjustment. After running the sequence for a number of times, the final design solution, which will be approved by both the designer and consumer, can be easily identified. Findings Design knowledge, which is already applied to normal body shapes successfully can be applied to 3D garment design using the concept which is based on collaborative design. Through this process, the classical 2D garment design knowledge, especially 2D patterns and design rules, can be modified and applied according to a normalized virtual garment sensory evaluation procedure quantitatively. This evaluation procedure, interactively performed by the designer and consumer, can permit to adapt the finished product to disabled people afflicted with severe scoliosis. The proposed method is also validated to be more advanced compared to 2D-to-3D virtual CAD design method, especially for atypical morphologies. Originality/value As a co-design method, 3D virtual draping and sensory evaluation can fully satisfy the interaction between the garment design technical space and perceptual space of the finished garments ensuring desired 3D garment fit effect by adjustment of technical parameters. 3D scanning technology is used to generate a complete digitalized 3D human model, permitting to extract the main features of body shapes without accurate measurements. As a knowledge-based design process, both the fashion design knowledge and the pattern making knowledge will be extracted to provide inspirations and references. Successful design solutions will be incorporated into the fashion design knowledge base in order to generate new design rules and enhance professional design knowledge.

Designing the functional garments for people with physical disabilities or kyphosis by using computer simulation techniques

“…An early stage of this newly developed analysis methodology has already been proposed in a research by Cupar et al [24]. In the research works by Hong et al the method for generating of the two-dimensional (2D) basic pattern designs for physically disabled people with scoliosis was presented by using the three-dimensional (3D) virtual technology [25][26][27]. In this two-fold study, we focused on designing of functional garments for people with physical disabilities and postural disorder kyphosis by using the 3D scanning, CASP methodology and computer simulation techniques.…”

Raincoat design for children for age group 7-8 years: A design development case study

“…User involvement is a widely accepted principle in a successful product development process [5]. A lack of user involvement has been repeatedly associated with failed product development projects and the benefits of user involvement have been shown in several studies [6,7]. Analysis and integration of user needs can largely increase user involvement and lead to the success of product development [8].…”

Garment opening position evaluation using kinesiological analysis of dressing activities: case study of physically disabled people with scoliosis (PDPS)

“…The proposed garment block, whose wearing ease was considered, fully followed the protruding parts of the PDPSs and improved the depressed parts, which ensured a good garment fitting. 13 This design process is described as follows:…”

“…Compared with other disabilities, PDPSs face more difficult situations in choosing ideal garment products. The existing literature about garment adaption for PDPSs focuses on solving the problem of garment construction along with fit 13 and wearing ease control. 14 For example, in previous research, authors developed a method using 3D virtual prototyping to create a fit-ensured garment for PDPSs in a virtual environment.…”
