The study goals are establishing a library management plan for the school for the blind in Korea and also developing a structured library program, which reflected the patron's perception. We surveyed the students in three schools for the blind to identify their perception and usage statistics of the libraries. The analysis of the survey led to a school library program framework consisting of four types. To verify the applicability and effectiveness of the framework, we designed ten programs to meet the needs of the schools by consulting respective school's teachers. We administered the second survey after the classes, and we found that there were positive increases in the frequency of library use, a number of books read, perception about the libraries, amount of information used, and self-directed learning willingness.

This paper introduces an electronic travel aid, named SmartWand, which detects obstacles using a ultrasonic sensor. In addition to obstacle detection, the SmartWand senses color information of objects and the environmental brightness. It is designed to be attached to a ordinary white cane in order to detect the obstacles at head-hight which cannot be covered by the cane. We have improved the first version of the SmartWand based on a user evaluation. The second version is much lighter and smaller than the previous one. It has been enhanced by two new functions. The SmartWand eliminates impact errors due to tapping the ground using a moving average filtering algorithm and restricts the detection range to the path in the moving direction using an acceleration sensor. We have tested these functions in various environments to determine the parameters for these functions.

In this study, we introduced the technique of matching classical music using deep learning to design soundscape that can help the viewer appreciate painting and proposed an evaluation index to evaluate how well matching painting and music. The evaluation index was conducted with suitability evaluation through the Likeard 5-point scale and evaluation in a multimodal aspect. The suitability evaluation score of the 13 test participants for the deep learning based best match between painting and music was 3.74/5.0 and band the average cosine similarity of the multimodal evaluation of 13 participants was 0.79. We expect multimodal evaluation to be an evaluation index that can measure a new user experience. In addition, this study aims to improve the experience of multisensory artworks by proposing the interaction between visual and auditory. The proposed matching of painting and music method can be used in multisensory artwork exhibition and furthermore it will increase the accessibility of visually impaired people to appreciate artworks.

When a human being grew older, followed by visually and perceptually impaired, and dementia, it jeopardizes safety and life unless supportive design is secured for a living environment. This supportive space is based on universal design concept which offers safe-oriented, and simple use by incorporating gender and physical/mental limitation. The study of purppose was to examine the appropriateness of barrier-free standard for seniors' living in apartment through IPA. Chi-square analysis found that satisfaction with BF space is lowered as aging is continued and for female group. Regression analysis indicated that sink was the prime predictor in satisfaction, and stair/elevator was the most important variable. IPA concluded that sink, bath, shower/locker and alert/egress were prime BF indexes to be improved among 14 elements, implying careful design in sanitation area for seniors.

Lately the VR (Virtual Reality) game genre is becoming increasingly more popular and it has been cementing its place in the market as its own independent game genre. The key advantage of VR is that it lowers the barrier between player and the virtual world, thus creating an immersive experience. The suggested method develops a game that allows the player to experience what it is like to be visually impaired using the unique characteristics of VR. A distinctive feature of this game is that the character is provided only a limited range of sight, which is created using silhouette outlines. This restrictive visual field is then grafted onto VR and the player can indirectly experience blindness in a highly immersive manner. The silhouette outline along with the particle system is created using Oculus Rift, a headset highly used in VR game development, and Unity 3D game engine. We will also explain in detail regarding the removal of borders between the objects.

Objective: The aim of this study is to predict human visual target search using ACT-R cognitive architecture in real scene images. Background: Human uses both the method of bottom-up and top-down process at the same time using characteristics of image itself and knowledge about images. Modeling of human visual search also needs to include both processes. Method: In this study, visual target object search performance in real scene images was analyzed comparing experimental data and result of ACT-R model. 10 students participated in this experiment and the model was simulated ten times. This experiment was conducted in two conditions, indoor images and outdoor images. The ACT-R model considering the first saccade region through calculating the saliency map and spatial layout was established. Proposed model in this study used the guide of visual search and adopted visual search strategies according to the guide. Results: In the analysis results, no significant difference on performance time between model prediction and empirical data was found. Conclusion: The proposed ACT-R model is able to predict the human visual search process in real scene images using salience map and spatial layout. Application: This study is useful in conducting model-based evaluation in visual search, particularly in real images. Also, this study is able to adopt in diverse image processing program such as helper of the visually impaired.

The World Health Organization estimated that more than a billion people (or 15% of the world's population) lives with disabilities. They have the same information needs as non-disabled people. Nevertheless, as the World Blind Union estimated, less than 10% of published books are ever made into accessible formats in developed countries. The role of the national library should be very important to improve the information accessibility for the disabled. Based on this perspective, this study analyzed and compared the history and development, legal basis and organization, main functions and tasks, and service features for the disabled for the Library of Congress of the United States, MTM(Myndigheten för Tillgängliga Medier) of Sweden, National Diet Library of Japan, and SALB (South African Library for the Blind) of Republic of South Africa representing the nationwide disability services by continent. And based on the results of the analysis, this study suggested ways to strengthen the capacity of the National Library for the Disabled of Korea.

The latest hardware and software techniques are combined to give safe walking guidance and convenient service of realtime walking assistance system for visually impaired person. This system consists of obstacle detection and perception, place recognition, and sign recognition for pedestrian can safely walking to arrive at their destination. In this paper, we exploit the sign object detection system in subway station for sign recognition that one of the important factors of walking assistance system. This paper suggest the adaptive feature map that can be robustly extract the sign object region from complexed environment with light and noise. And recognize a sign using fast zernike moment features which is invariant under translation, rotation and scale of object during walking. We considered three types of signs as arrow, restroom, and exit number and perform the training and recognizing steps through adaboost classifier. The experimental results prove that our method can be suitable and stable for real-time system through yields on the average 87.16% stable detection rate and 20 frame/sec of operation time for three types of signs in 5000 images of sign database.

This article describes several clinical usefullness of the telephone in psychotherapy with adolescents through case analysis by Tolchin, and discussed various management problems and some practical guidelines for therapists planning to utilize telephone psychotherapy with adolescents through literature analysis. In general, most adolescent patients in regular treatment benefit from knowing that the therapist can be reached by phone and that their call will be returned that same day. The therapist's telephone availability helps the young patient to develope a positive working alliance. Telephone psychotherapy had it's first widespread application in crisis intervention and suicide prevention. It's current uses also include enhancement of self-control in cases of self-destructive adolescents, and management of anxious, depressive, or anorexic adolescents. In addition, such widely divergent modalities of treatment as follow up of patients discharged from a psychiatric hospital, alcoholic rehabilitation programs, drug hotlines, sex counselling group therapy for visually impaired elderly, control of separation anxiety in girls, resolution of fear on the mental disorders, and helpful modality to continue psychotherapy without geographic barrier during longer periods of separation with therapist are currently available via telephone. But telephone psychotherapy is generally not suitable for more self-defensive and introverted cases, more dependent chronic callers, silent cases, test callers. the cases of telephone scatologias, the cases of intellectualized discussion, of more dependent cases calling phone in order to get attention from therapist. Telephone psychotherapy for adolescents serves as an important and useful method in the therapeutic armamentarium for this most challenging and rewarding population.

Student halls and their convenient facilities have been a focal point for various student activities at university campus. It has been for most of the student a place of unique memories and of attachment often associated with those good and bad school days. However, it is questionable whether these facilities are supportive and accessible for all of the students and other users including the handicapped. Therefore, based on the concept of UD(universal design) which was widely applied to U.S. institutions, this study intended to evaluate student hall facilities in U.S. and to provide an improvement direction for Korean UD application. For that purpose, four universities were selected for an in-depth analysis and 76 survey indices were utilized based on previous research. It was found that (1) design consideration without braille sign for VIP(visually impaired person) in student buildings can be differently approached with electronic devices; (2) the best demonstration of UD in student buildings can be seen in spacious flat pathway, easy access through ramp and wide entry area, necessary for people in wheel-chairs, but used by all, implying an increase of the ratio of public space; (3) one of the good UD features is an attractive physical environment rather than institutional appearance, in which they ultimately will support and completely adaptable at optimal levels by everyone; (4) consistent maintenance and management maximize the potential of UD principles and minimize physical limitations.
