Background: This study was conducted to prove the effects of the Schroth exercise on sagittal postural alignment to the visually impaired students. Methods: The subjects were 8 students who attend the special school in Daegu and performed the Schroth exercise 3 times per week for 3 weeks. Craniovertebral angle and pelvic alignment were measured to compare the effects of the exercise. Results: Craniovertebral angle and pelvic alignment on sagittal plane showed significant differences (p<.05). Conclusions: Schroth exercise was effective to improve postural alignment of sagittal plane to the visually impaired students and these results will have a positive impact on future study of improvement of postural alignment on sagittal plane to the visually impaired students.

We have proposed an indoor positioning system for moving objects and/for the blind or visually impaired to play various sports. [ for a blind or visually impaired playing various sports.] This system consists of a wireless heart rate monitor, wireless sensor network and / 4 ultrasound satellites [ configuration with four ultrasound satellite modules) at the corners of the room. This system provides / the real-time measurement of the location and heart rate of the person in the room[ non-invasive measurement method of the heart rate and the location of a person in real time ], and will help the [a] blind or visually impaired enjoy sports more easily.

People with visual disabilities suffer environmentally, socially, and technologically. Navigating through places and recognizing objects are already a big challenge for them who require assistance. This study aimed to develop an android-based assistive application for the visually impaired. Specifically, the study aimed to create a system that could aid visually impaired individuals performs significant tasks through object recognition and identifying locations through GPS and Google Maps. In this study, the researchers used an android phone allowing a visually impaired individual to go from one place to another with the aid of the application. Google Maps is integrated to utilize GPS in identifying locations and giving distance directions and the system has a cloud server used for storing pinned locations. Furthermore, Haar-like features were used in object recognition.

현재 구현된 시각 장애인을 위한 Navigation System들은 통신거리가 짧게 제한되어 있고 장애인으로부터 받을 수 있는 정보가 직접적으로 도움을 주기에 부족한 면들이 있다. 반면에 장애인들이 이동하는 경로는 불완전한 편의시설이나 안내로 인해 아직도 White Stick 만으로 이동하기에 불편하고 위험하다고 할 수 있다. 이런 점을 해결하고자 장애인과 도우미간에 영상, 음성, 위치정보를 주고받을 수 있도록 Android Platform과 PC간의 1:1 통신을 구현하고자 한다.

There are many assistive devices for the visually impaired. They are becoming smart. In this paper, we propose a device that help route guidance for a visually impaired person. It is composed of a smart phone, cane, and hands-free devices. The smart phone helps a route guidance. The cane detects an obstacle and transmits it to the hands-free device. The hands-free device communicates with a visually impaired person. We here present their architecture, signal flow, configuration, and their circuit diagrams.

Nigeria's non-government organization (NGO) libraries for the visually impaired has over the years been at the forefront of information services provision to persons with visual impairment. This study adopted a survey research design to investigate use of alternative formats and perceptions of information services to the visually impaired, focusing on two purposively chosen NGO libraries for the visually impaired in Nigeria. Using a complete enumeration approach, data were gathered from 180 users of the libraries through the use of a structured questionnaire with a reliability score (${\alpha}=0.74$). Data from 112 (62.2%) of the 180 administered copies of a questionnaire that were retrieved were analysed. The study found that Braille materials had a high level of utilization ($\bar{x}=4.46$) and were the most frequently utilized (90.9%). Perception of information services by the visually impaired was positive while use of alternative formats was significantly and positively related to users' perception of information services (r = .041; p < 0.05). The study recommends improved transcription and investment in alternative formats and in e-resources. It also recommends collaborations to widen access as well as constant evaluation of services.

Purpose: This study aimed to understand and describe the diabetes self-management experience of visually impaired people with diabetes. Methods: Ten participants were recruited through a website used by the visually impaired from February to March 2020. Data were collected through two focus group interviews conducted in June 2020; each group consisted of five participants. All interviews were recorded with the consent of the participants and transcribed verbatim. The transcribed data were analyzed using qualitative content analysis. Results: Seven categories were as follows; a two-faced, lifelong companion, an unprepared encounter, struggle to live, love-hate relationship with family, strategies to adapt, lessening attention to self-management, the desire to learn properly. Conclusion: It can be concluded that the visually impaired have fewer opportunities for receiving diabetes self-management education than general diabetic patients. Consequently, plans to improve the education available to such patients are required. Additionally, psychological counseling and diabetes education for patients' families are necessary, and improving the perception of medical workers regarding the visually impaired will be prove useful.

The purpose of this study was to examine visually impaired people's clothing behavior, using a qualitative approach. The results are intended to be used as baseline data to make an instrument that can measure the factors that have an effect on visually impaired people's clothing needs from the perspective of environmental and social relationship contexts. This study was made through in-depth interviews with people with grade-1 visual impairment, and the results were as follows: First, when purchasing clothing, they were accompanied by trusted people, and chose trusted brands and trusted products. They spent as little time as possible, did not try on many clothes, and they preferred colors, designs, and purchase methods that carried as low a risk as possible. Second, they wanted basic product information and simple procedures when purchasing and using clothing products. Third, they were able to manage their own clothes themselves. However, there was insufficient laundry information available. Fourth, the main reason why visually impaired people took care of their appearance was that they wanted to look neat and clean to be respected by others. Based on the study results, it is necessary to provide information on clothing to improve quality of life and welfare and thus ensure visually impaired people's independence.

Disasters are now becoming commonplace and especially the vulnerable group such as the disabled, the elderly, children and foreigners are in a state of overlapping disasters. In this situation, ATSC 3.0-based UHDTV disaster information service for the visually and hearing impaired has been developing. This study focuses on the demand data collected through in-depth interview with the impaired. The demand analysis data is very important to development process of technology. The results of the interview show that it is essential to link the UHDTV disaster signals with home-network, IoT, wearable devices, and various assistive devices for the impaired (hearing aid, smart light bulbs, warning light, etc.). In outdoor space, UHDTV disaster information must be connected to public display media, digital signage, kiosk, screens in bus or taxi. If communication aids for the visually and hearing impaired are equipped with a function that can transmit and receive disaster information, it will help to minimize disaster damage.
