  • Until now, there were few supports on reading the mathematical expressions except text based expressions, so it is important to provide the reading of the mathematical expressions. Also, there are various of obstacles for people who are not visually impaired when reading the mathematical expressions such as the situation of presbyopia, reading the mathematical expressions in the vehicles, and so on. Therefore, supports for people to read mathematical expressions in various situations are needed. In the previous research, the main goal was to transform the mathematical expressions into Korean text based on Content MathML. In this paper, we expanded the range of the research from a reading disabilities to people who are not reading disabilities. We tested appropriacy of the rules we made to convert the MathML based expressions into speech and defined 3 math-to-speech rules in korean based on levels. We implemented the mathematical expressions by using 3 math-to-speech rules. We took comprehension test to find out whether our math to speech rules are well-defined or not.

  • Existing input devices for desktop computers are not suitable for wearable computers because they are neither easy to carry nor convenient to use in a mobile working environment. Different input devices for wearable computers must be developed. In this paper, a wireless glove-based input device for wearable computers is proposed. The proposed input device consists of a pair of chording gloves. Its keys are mounted on the fingers and their chording methods are similar to those of a Braille keyboard. RF (Radio Frequency) and IrDA (Infrared Data Association) modules are used to make the proposed input device wireless. Since the Braille representation for numbers and characters is efficient and has been well established for many languages in the world, the proposed input device may be one of good input devices to computers. Furthermore, since the Braille has been used for visually impaired people, the proposed one can be easily used as an input device to computers for them.

  • As the seniors and the disabled has increased, the demand for cultural centers has also increased in many local areas. This means that the local cultural centers designed from the viewpoint of universal design are needed, so that to be used by everyone without any difficulties. This study examined the applicability of universal design principles to the public service areas of the local cultural centers. The subject cultural centers were three local ones which had seating capacity of more than 1,000 and opened after the year of 2,000 in Gyungnam. The spatial scopes of the study were six public service areas of the local cultural centers : entrance area, corridor and pathway, stair, ramp, elevator, and rest room. The total 65 items for evaluating the applicability of universal design were selected and examined for six areas. On the whole, accessibility, such as wide pathway and flat floor was good. However, the following improvements were needed. 1) Handrails and rounded corner were needed on walls. 2) Consideration of the visually impaired like as braille sign was needed. 3) The handrails on ramp should be installed for usability. 4) The automatic door would be more useful to the physically disabled users. 5) Wider space and familiar handrail design and color were needed in the rest rooms for the handicapped.

  • The idea I set my thesis upon was to develop a methodology for the visually impaired to perceive an environment through their other senses. Since the Blind perceive spatial relationships by combined association of their other senses, it was essential to create a setting where their senses can be amplified. Thus this garden was designed to accommodate two or more of blind person's senses at once to provide more of '3-D' spatial relationship. The main goals of this thesis are, first, to create a place where the Blind can enjoy and nurture their own specific interests. Second, to reveal the nature in its allowing individual analysis and interpretation of a garden. Third, to move away from the prejudice of gardens for the Blind being made of only touching and smelling. To achieve these goals, the most important task was to establish a sense of space. In order to do so, five principles were used; Perspective, Enclosure, Light/Shade, Form, and Environment. After all, the garden for the Blind does not proclaim its purpose in loud terms nor in obvious manner. It should attempt to provide joy, serenity, and activity; a freedom to choose, recognize and analyze nuances of garden, the rhythm of enclosure and openness to experience variety, also to delight in subtle changes and to just imagine.

  • Excessive stress is harmful to academic performance in children and may lead to dropping out of school. To meet the demands of a modern life-style which is full of speed, stress and tension, an all-round child health program is crucial. The use of yoga for children has diverse applications in maintaining and developing their physical, mental, intellectual, emotional and spiritual levels. Yoga, through its physical postures (asana), breathing practices (pranayama), cleansing techniques (kriya), meditation therapies (dhyana) and relaxation training (yoga nidra) yields a positive effect in the management of stress in children. Yoga practice benefited children by improving their eye-hand coordination, attention span, levels of concentration, competitive performance and relaxation. Visually impaired children showed a significant decrease in their abnormal anxiety levels when they practiced yoga for three weeks, while a program of physical activity had no such effect. Socially disadvantaged children in a remand home showed significant improvements in sleep, appetite and general well being, as well as a decrease in physiological arousal after yoga. In one study, it is found that a 4-week program of asana and meditation lowers the aggressive behavior of children. Meditation helped to reduce problems related to maladaptive behavior, increase emotional and physical health and psychological well-being in children. Finally, the possible role of yoga in improving the mental state and general well-being of children with cancer is being explored.

  • In various industries, tactile recognition has been one of the important ways in displaying information because peoples like to touch and feel. Especially, how much the tactile information is efficiently recognizable is crucial for visually impaired persons in their daily lifes. However, existing design guidelines are insufficient to lead good tactile recognition. In this study, an experiment was performed to investigate proper tactile shapes (relievo / intaglio vs. filled / unfilled), sizes and depths for efficient tactile recognition. Moreover, this study scrutinized whether the recognition speed or error was varied depending on the type of displayed symbols (open vs. closed types) in tactile. The experimental results revealed that the 'relieve-filled' shape type was more rapidly recognizable than the other shapes, and the 'closed' type symbols (e.g., ${\square }$. ${\bigcirc}$) were more robustly recognizable than the 'open' type symbols (e.g, +, ^). Several design guidelines were presented based on the results. These guidelines can be applied to the design of tactile buttons in the devices that users should control them without visual attention, such as car steering wheels or MP3 players.

  • 현재, 시각장애인들이 보행 시 경로 안내를 제공받는 방법은 청각을 사용하는 것이다. 이로 인해 시각장애인의 보행시 안전이 매우 위험한 상황이다. 비장애인은 시각과 청각을 모두 활용해 길 찾기가 수월하지만, 현 시점에서 시각장애인은 오직 청각에만 의존해야 한다. 보행 시 교통사고 사망률이 OECD 평균의 두 배를 웃도는 대한민국에서 시각장애인들이 거리를 도보하기에는 더더욱 위험한 현실이다. 이에 대한 대책으로 본 논문에서는 아두이노를 사용해 촉각기반 네비게이션을 만들어 시각장애인의 교통사고 발생율을 낮추려고 한다.
