The increase of wheelchair users due to the rapid growth of elderly population, traffic accidents, and industrial disaster etc. becomes a major issue in our society. Thus, the Convenience Promotion Law was enforced to facilitate the use and installation of convenient facilities for the disabled, the elderly and pregnant women. Currently, not only newly built buildings but also roads and parks are accessed and used by all the people without any hindrance. In contrast to this, so far not many studies on residential space design for wheelchair users have been carried out except for public facilities. So, wheelchair users have to bear the inconvenience in their houses made upon the standards of the general people. Therefore, it is necessary to develop design guideline considering the physical characteristics of wheelchair users and their family members to lead a convenient life. This study was conducted in universal design perspective and intended to establish design guideline of convenient residential space for wheelchair users and general people. To accomplish the objective, surveys for wheelchair users' actual conditions and needs, and video observation were carried out.

The purpose of this study is to analyze the physical characteristic by directly measuring the wheelchair using disabled women and to classify Body Type of a disabled person. The subjects were 103 disabled women of wheelchair used women and between 20 - 55 years of age The result of this study is as follow. 1. There was a remarkable difference in the physical characteristic of wheelchair using disabled women due to their cause of disability. The cause of disability was classified into the 4 groups; Poliomyelitis, Spiral Cord Injury, Muscular Dystrophy, Cerebral Palsy. 2. The result came out to be 4 factors by the factor analysis on the data of an anthropometric measurement to the wheelchair using disabled women and also cluster analyzing the factor scores, the experiment was concluded to 4 types. Type 1 came out to be a short height with the shortest legs. Type 2 was body shape which had a corpulent upper body and wide shoulder but with short and slim lower body. Type 3 has the shortest height, weak and lean upper body, small shoulders Type 4 has the largest stature and legs 3. A comparison of anthropometric measurements of wheelchair using disabled women with National Anthropometric Survey Korea(1997) was significant difference

The purpose of my study is to provide some information on clothing for the handicapped with special needs. So I have designed clothes for the handicapped to provide some solutions for their clothing problems. These clothing designs for crutch and wheelchair users were based on solutions proposed by many researchers. The number of handicapped has been increasing gradually for years, especially the physically handicapped. Although they make use of many instruments for ease of movements and other physical conditions, most of the handicapped generally use crutches and wheelchairs. So I designed clothing for the crutch and wheelchair users. In order to ease problems in dressing and undressing, when using the crutch and wheelchair, various physical attributes of clothing should be considered: (1) Selection of fabric, (2) construction and location of the opening, (3) type and location of fastenings, and (4) design of garments for comfort and ease of movement. Clothing should also be able to satisfy psychological needs related to attractive appearance. My designs have proposed seven items of clothing. These include a cape-coat, over-blouse, one-piece dress and an pants for the crutch users. Also, a shirts, pants, and wheelchair wrap for wheelchair users will be displayed.

This study aims at establishing a sizing system required for producing ready-made clothes which can fit the body shape of disabled men using wheelchair. It measured the bodies of 178 adult men using wheelchair and compared the sizing system of German adult men using wheelchair (1984) with KS system(KS K0050, 2004) in order to establish standards of the sizing system. AS a result, in terms of classification of body shapes, KS system cover more types of disabled men's body shapes and especially, A types (Drop 15.6) showed the widest coverage with 32%. In classification of heights, the widest range of height was 170 cm, and Korean men's four sizes between 158 cm and 176 cm covers 88.2% of disabled men's body shape. For chest size, 91.1% of disabled men's chest sizes were included in seven sizes, which are 4 cm intervals between 88 cm and 112 cm with 100 cm standard. In consideration of the ranges of height and chest, the general sizes (A types; 11 sizes, B types; 3 sizes, Y types; 5 sizes) are selected to present the standardized measurements. Basic parts of the upper garment sizing system for disabled men using wheelchair were height-chest-waist size.

As one of the most widely used assistive technology devices for the disabled in Korea, the powered wheelchair conforms to KS P ISO 7176-5 standard size which uses original version of international standard, ISO 7176-5 without technological modification. However, the international standard is not suitable for the disabled in Korea because it defines the size of wheelchair based on the body size of foreigners, which causes imbalanced posture due to limitation of movement or rotation of pelvis, pressure ulcer incidence due to excessive pressure on the thigh or popliteal space and calf, and safety of reduction due to improper posture. This study suggested the guidance of size for powered wheelchair based on human body size examined by Korean Agency for Technology and Standards, showing a great difference from the size defined in KS P ISO 7176-5 and accordingly redefinition for the size of powered wheelchair is needed.

To improve the social and economic position of the disabled people and secure their human rights, an integrated society should be buill. To build such a society, an adequate access should be provided to the movement or in using buildings or facilities. The inconveniences from social life on the part of the disabled people might not result from their impairment or disability, but from physical and social barriers in the environment surrounding them. Therefore, it is necessary to reconstruct entire systems of the society as a disabled people-friendly structure in order to remove those barriers, make them stand their own feet in our communities and freely participate in the social activities. This will eventually lead to build a society in which all people including the disabled people can use those facilities in a more convenient way. It is almost impossible for the disabled people to safely and conveniently access to and use facilities and equipments and freely move to their desired places, without any help from others in Korea. Even though, there are currently many disabled people-related convenience facilities, they have been independently built without a connection with other facilities and buildings, thus not greatly useful. Even when convenience facilities have been built, mostly they are superficially set up; therefore, in many cases, the disabled peOple cannot use those facilities. In this. research, I tried a new concept of mobile wheelchair lift design, which the disabled people can operate without restrictions, when using the public facilities. The key to this research was to develop the existing import-oriented simple functional products to a new system with functional safety and high quality orientation. Also, this research aimed at bringing an. import substitution effect, as well as preempting the mobile wheelchair lift market by advancing into overseas markets through application of new image designs in the field of disabled people aid equipments.

We propose an EMG-based input interface technology for helping the tetraplegic to utilize mouse, keyboard and power wheelchair. Among possible actions for the tetraplegic utilizing these devices, teeth-clenching is chosen as an input action. By clenching left, right or both teeth, and controlling the clenching duration, several input commands for utilizing the devices can be conducted. EMG signals generated by teeth-clenching are acquired around one's left and right temples and they are used as control sources for utilizing the devices. We develop signal acquisition devices, signal processing algorithms, and prototype systems such as power wheelchair control, mouse control, and game control. Our experimental results with the tetraplegic show that the proposed method is useful for utilizing the devices.
