As task force members, we present the International Astronomical Union (IAU) Office of Astronomy for Development (OAD) and its task forces. Each task force calls for proposals every year and reviews the submitted proposals. From the point of view of "Astronomy for a Better World", the vision of the OAD, our aim is to reach diverse people including those such as the visually impaired. Our efforts meet one of the goals of the OAD and some OAD-funded projects.

People have experienced physical problems including vision problems with aging; some are normal and some are abnormal. When they have abnormal and impaired vision, they have a lower level of life satisfaction than their sighted peers. For the elderly with sight loss, well-designed housing could be an important indicator for their quality of life. Housing adjustment and modification could help the elderly cope with sight loss, do daily activities more independently, and lead to better quality of life. The purpose of this study is to investigate housing conditions for the elderly with vision impaired, state of housing adjustment or modifications, and the effects of housing conditions on the wellness of the elderly in Korea. For this study, 18 housing cases were investigated and a total number of 65 visually impaired people aged over 55 participated. Housing condition of those participated was poor. Most observed home hazards are level differences in living areas, obstacles in the hallway, confined space that is not allowed structural modification, swing doors from wardrobe or cabinets, color contrast, poor lightings, and etc. Majority of households participated in this study did not make modification or refurbishments, rather many of them tend to adapt themselves to their residential environments. Older adults living in better housing condition and under less difficult environments are likely to have higher life satisfaction. The effects of housing condition on wellness could be more influential when individual capabilities (e.g. health condition) are weaker. The findings underline that with intervention of individual characteristics, the effects of housing and physical environment on negative outcomes of vision loss would get ameliorated or reduced.

This research focuses library services for people with disabilities in public libraries and draws many issues and the difficulties faced by the libraries. Data are collected and analyzed based on a survey conducted by the National Library Support Center for the Disabled. As a further research users with disabilities study is recommended. Apart from the visually impaired, people with hearing impairment and physical impairment should be included.

For people with physical or sensory limitations, broadcasting is the main means of information acquisition and leisure. Recently, changes in the media environment, such as convergence of broadcasting and communication, digital mobile conversion of broadcasting, and active media usage behavior of users, make broadcasting accessibility of the disabled difficult, and as a result, the information gap between the disabled and the non-disabled is increasing. A notice on broadcasting rights for the disabled was enacted in consequence of the amendment of the Broadcasting Law in July 2011 and the web accessibility guideline became more effective with the amendment of the National Informatization Act in 2013 so that legal basis for the right of media access for the disabled was established. However, media services for them are still lacking quantitatively and qualitatively. In this study, we describe the present status of the audio description service for the visually impaired, and analyze the results of the questionnaire survey on the usage status, satisfaction and improvement requirements of the audio description service for 100 visually impaired people.

The audio vision system was developed for visually impaired people and usability was verified. In this study ten normal volunteers were included in the subject group and their mean age was 28.8 years old. Male and female ratio was 7:3. The usability of audio vision system was verified by as follows. First, volunteers learned distance of obstacles and up-down discrimination. After learning of audio vision system, indoor and outdoor walking examination was performed. The test was scored by ability of up-down and lateral discrimination, distance recognition and walking without collision. Each parameter was scored by 1 to 5. The results were 93.5 +- SD(ranges, 86 to 100) of 100. In this study, we could convert visual information to auditory information by audio-vision system and verified possibility of applying to daily life for visually impaired people.

This paper evaluates web accessibility using an evaluative measure of K-WAH 3.0. It targets systems and contents in scientific and technological information, based on a guide for 'Internet Web Contents Accessibility 1.0'. The result indicates that web accessibility of informational system is lower than that of informational contents. Based on this fact, this paper identifies the main characteristics and differences of web accessibilities in informational system and contents, and discusses possible improvements. the result of the evaluation found the scientific system sites is more superior than contents sites in web accessibility. And the scientific system and contents sites except NDSL was lest 'understandable' and 'Robust' in observance. Therefore web page that should bring "easily understandable" and "reducing outstanding side effects" was required.

Currently, blind people are experiencing a lot of inconvenience in their daily lives. In order to provide helpful service for the visually impaired, this study was carried out to make a new smart glasses that transmit information monitoring walking environment in real-time object recognition. In terms of object recognition, YOLOv4 was used as the artificial intelligence model. The objects, that should be identified during walking of the visually impaired, were selected, and the learning data was populated from them and re-learning of YOLOv4 was performed. As a result, the accuracy was average of 68% for all objects, but for essential objects (Person, Bus, Car, Traffic_light, Bicycle, Motorcycle) was measured to be 84%. In the future, it is necessary to secure the learning data in more various ways and conduct CNN learning with various parameters using darkflow rather than YOLOv4 to perform comparisons in the various ways.

A white cane is used by many people who are blind or visually impaired. The studies and developments in the field of smart electronic white cane have been progressed to improve walking safety of the visually handicapped person. In this paper, we describe a situation-awareness white cane which support and guide walking of the visually handicapped person by giving information of surrounding situation through connection of a white cane and a mobile device. There are easily accessible buttons in the situation-awareness white cane. These buttons is connected with the mobile device by blue-tooth, so by pushing these buttons, the visually handicapped person can receive sound-guidance. As a result, the visually handicapped person can walk more safely by getting more information of situation.

Information technology and internet became necessities of life facilitating communication and information access. Physically handicapped people, who cannot access to new Information easily due to economic, technical and physical handicaps, are likely to live with severe disadvantage in the high-speed information society in which information access right is considered as one of the basic human rights. Therefore, It is highly desirable to develop and improve library service programs for visually imparied at public libraries. In this study, the analyse of service activities for the visually unpaired at Hanbat Public Library and the investigation of user's needs and provider's points of view of staff members through individual Interviews were followed by the propositions gor the Improvement of services at local public libraries. And the consrtuction of cooperative networks with proper role-shares among service rooms for visually Imparired In public libraries, special libranes, social welfare organigations and government offices was confrimed to be the most urgent task.
