According to the Ministry of Employment and Labor survey (2019), the number of deaths from industrial accidents decreased by 0.4 percent year-on-year, but the number of fatalities increased by 8.5 percent year-on-year. This indicates that the death rate has decreased due to the extension of life expectancy due to the development of medical technology, but the number of people suffering from lifelong disabilities such as accidents and industrial accidents is increasing. People with moderate disabilities who suffer from acquired disabilities due to industrial accidents may feel depressed due to self-reliant living restrictions, anxiety about returning to society, and hopelessness to live with disabilities for the rest of their lives. In order for people with industrial accidents to regain their motivation for life and restore their confidence, multidirectional treatment such as mental and psychological treatment and social vocational education is needed.
This study is aimed at improving the mouse design of wooden design classrooms and computer classrooms, which show high inconvenience in tools used for professional vocational education for the disabled.
Based on literature research on rehabilitation and disability, the research method reconstructed the five principles of fairness, manipulation intuition, convenience, safety, and aesthetics for universal design grafts, and proposed training tool design through a User Coded Design (UCD) process. The questions in the survey for design derivation and user opinion survey consisted of seven inconveniences and nine design improvements for tool use through interviews with special rehabilitation teachers, and were based on a five-point scale for writers to easily understand and answer the survey. As a survey analysis method, frequency analysis, correlation analysis was performed using SPSS statistical program 27, and the analysis results were objectively interpreted through interviews with trainees in special rehabilitation wooden classes and computer classrooms. Based on the analysis results, we proposed a tool design used in training and conducted a Product Performance Program (PPP) evaluation based on the five principles reconstructed in this paper to demonstrate objective universal design achievement for improving the use tool design.
The study found that physically constrained industrial disabled people generally have difficulty using distributed tools reliably in special rehabilitation training, and that they cannot use the tools in the right posture.
The results of a survey of 80 special rehabilitation trainees to improve tools are linked to related items of form, exercise, and sensory discomfort and design improvement elements. The inconvenience of usability (motor factors) in group A of wooden classrooms classified based on the Ministry of Health and Welfare's Disability Assessment Criteria can be linked to safety (motor factors) and intuition (motor factors), and inconvenience (motor factors) can be linked to convenience (motor factors). The inconvenience of lack of consideration (motor elements) in Group C can be proposed by linking the improvement factors, intuition (motor factors) and convenience (motor factors). Slippiness (sensory factors) of a tool can be linked to physical strain and injury, thus improving safety (motor factors). The inconvenience of Group A's feeling (morphological factors) and lack of consideration (motor factors) in computer classrooms can be linked to convenience (motor factors), which is an improvement factor, and usability (motor factors) to intuition (motor factors). The discomfort with Group B's usability (motor factors) can be linked to the improvement factors convenience (motor factors) and aesthetic (morphological factors), and the discomfort with coldness (sensory factors) can be linked to the material (sensory factors). The direction of design improvement, which combines the contents of the investigation and the elements of the product, is to relieve the physical burden, make up for various forms of disability and physical discomfort without complications in use.
In order to evaluate the achievement of universal design of tools designed through research, the PPP evaluation conducted on two special rehabilitation teachers and 20 trainees (10 trainees in each classroom with high disability discomfort) showed high scores in convenience (4.93), safety (4.73) and mouse intuition (4.87). This confirmed that educational use tools were improved to design in compliance with universal principles, and based on this study, guidelines were presented for future research related to assistive tools for the disabled so that they can be used for research on assistive tools for the disabled. Through this study, we hope to strengthen the link between medical rehabilitation and special rehabilitation education for disabled people with industrial accidents and accelerate their return to society by increasing the rehabilitation effect of industrial accidents through professional vocational education.
