This study investigated the needs assessment of health education for adults with lately visual impairments. Focus group interview was conducted two times with 10 participants(4~6 participants/each). Most subjects addressed to have interest in social support group; health promotion behavior including exercise and having a positive mind; taking the medicine/supplements. Preferred contents of health education for adults with lately visual impairments were overcoming the depression, various exercise, maintaining of the healthy vascular, overcoming the insomnia, joint health, and diet which was different according to subject's health status. Also, care giver education was needed to help the subject to be independent on the activity daily living. These findings will be used to develop the design of health education programs for adults with visual impairments.

Tactile acuity was assessed in groups of control, blind, deaf, and blind caused by complication to investigate the effective tactile stimuli on tactile sensory substitution studies when tactile display is applied to persons with sensory loss of vision or hearing. Two-point discrimination and grating resolution were assessed by compass and JVP dome, respectively, in the hand, arm, neck, lumbar, and knee. In two-point discrimination by compass, control group showed the highest sensitivity in fingers among assessed body areas but did not show any significant difference between male and female. Blind group and deaf group compared to control group did not show any significant difference in fingers but showed lower sensitivity in arm and knee. In grating resolution by JVP dome, control group did not show any significant difference among five fingers as well as between male and female. Blind group showed higher sensitivity in five fingers compared to control group, but deaf group did not show any significant difference from control group. Blind caused by complication group showed lower sensitivity in two-point discrimination and grating resolution compared to control group and blind group. These results suggest that the body area and method of tactile stimulation, and difference in tactile acuity depending on underlying disease of sensory loss should be considered when tactile display is applied for sensory substitution.

The purpose of this study is to investigate the perspectives of science educators on the learning situations of visually impaired students through scientific inquiry in a darkroom. Twenty-four science educators who came to the annual conference of the Korean Association for Science Education volunteered to participate in 'the scientific inquiry in the darkroom' activities. They were encouraged to touch models of 'the molecular structure of ice' and 'the structure of eyes' and to discuss with participants during the activities. Surveys were done before and after darkroom activities, and the discussions during and after the activities were recorded and analyzed. As a result, participants recognized that science education for visually impaired students is both very feasible and necessary. Also, some of them, who have had an experience of teaching blind students and thought that they fully understood the learning situation of the visually impaired, were especially surprised by the fact that they did not actually understand how it was like to be a visually impaired and responded that they were able to more deeply comprehend the learning situation of visually impaired students through these activities. Through this experience, participants also became resolute to try more deeply to understand not only the visually impaired students, but also sighted students with learning disabilities. Based on these results, educational implications of scientific inquiry in the darkroom were discussed.

시각장애인의 보행을 보조할 목적으로 설치된 점자보도블록은 보행방향과 정지 정보를 제공하지만, 현재 위치에 대한 정보는 제공 할 수 없어서 보행 보조물로써의 기능이 매우 제한되어 있다. 본 연구에서는 최근 IT 기술중 하나인 RFID(Radio Frequency Identification)를 내장한 새로운 개념의 점자보도블록과 이를 활용하여 보행을 유도할 수 있는 시스템을 제안하고자 한다. 점자보도블록에는 RFID 태그와 안테나를 삽입하여 현재 위치에 대한 정보를 저장하며, 백색지팡이에는 이 정보를 읽어 들이기 위한 리더기를 설치한다. 현재위치에 대한 정보는 PDA로 전송되어 해당되는 음성정보를 시각장애인에게 전달하게 된다. 제안된 시스템을 통해 시각장애인은 타인의 도움 없이 현재 자신이 위치한 곳에 대한 정보를 얻고, 올바른 곳으로 보행중인지를 판단할 수 있게 되므로, 시각장애인의 보행권과 사회활동권등 복지 증진에 효과가 있을 것이다.

본 논문에서 제안하는 시각장애인용 스마트장갑은 시각장애인들이 지팡이를 사용할 때 발생하는 불필요한 접촉을 방지하고, 초음파센서를 이용해 전방의 장애물을 탐지하여 서보모터를 이용해 손등을 두드려 장애물의 유무를 알려준다. 또한 손가락에 있는 정전식 근접 터치 모듈은 손가락끼리 접촉하였을 때 블루투스로 연결된 스마트폰의 특정 어플리케이션을 실행하여 길을 잃거나 긴급 상황이 발생 했을 때 시각장애인도 불편함 없이 문자나 전화를 이용할 수 있도록 고안하였다.

장애인들, 특히 시각장애인들이 여가활동을 할 수 있는 게임이 많이 부족하다. 따라서 본 연구에서는 시각장애인과 비장애인의 여가활동의 격차를 줄이기 위해 함께 어울려서 즐길 수 있는 위한 게임을 구현하였다. 보다 몰입감 있고 활동적인 게임을 구현하고자 신체의 움직임을 센싱할 수 있는 Kinect를 활용하도록 구현하였으며 사용자는 왼팔과 오른팔을 이용하여 캐릭터를 움직여 게임을 즐길 수 있다. 게임의 진행 과정은 청각적인 정보로 전달되도록 구현하였다. 시각장애인들이 여가활동을 즐김과 동시에 신체를 활용함으로써 시각장애인들의 건강증진에 기여할 수 있을 것이다.

Electronic Travel Aids (ETA) developed for the blind such as sonicguide, mowat sensor and bionic C-5 laser cane have many problems like technical deficiency and high cost. Moreover, these systems have need for more training to perceive obstacle around. Therefore, In this study, we studied the blind's obstacle perception characteristics by human auditory sense, and development of ultrasonic ETA which have more simple usage, low cost and immediate usableness than present ETAs.

The study was to improve the right to the enjoyment of culture of persons with visual impairment by increasing the accessibility to art exhibitions and exploring assistive measures through needs assessment survey of persons with visual impairment on arts exhibition. We used total 83 responses collected through an online survey. The result are as follows. First, watching movies at a teather was the most frequent leisure activity among persons with visual impairment, while respondents reported attending art exhibitions as the least frequent activity. Yet, 71.1% included attending art exhibitions as one of their top 5 culture and leisure activities. Most of the respondents reported the purpose of attending art exhibitions as fun. However, a primarily visual atmosphere prevented them from visiting the exhibition. Second, persons with visual impairment preferred approaching the art to have a closer look. More than about 50% of the respondents used their residual vision. Most of the respondents reported to use more than two senses when appreciating the exhibits. Moreover, respondents reported that devices/services for multi-sensory experiences would be helpful to appreciate the art. The findings imply that the consideration of the characteristics and needs of persons with visual impairment is required for establishing the environment of art exhibitions. This could further contribute to the improvement of the right to the enjoyment of leisure and culture of persons with visual impairment and lead to the realization of social integration.
