For use in the guide system for the people who are visually impaired, an obstacle searching device using synchronous ultrasonic wave emission was proposed and developed. Generally, the conventional obstacle detection methods use the ultrasonic distance measuring device with successive scan method. However, the scan method causes a theoretical error and it couldn't estimate accurate obstacle distances. The proposed synchronous firing method use the plural number of ultrasonic sensors which emit ultrasonic wave simultaneously and estimate the distance to the closest obstacle relatively accurately. We analytically analyzed the errors of the conventional and proposed methods and compared the quantitative differences of the errors. The differences verified by obstacle search experiments. Using the proposed ultrasonic wave synchronous firing method, 3 dimensional obstacle location estimating device was designed and implemented. The results of the 3 dimensional obstacle detecting experiments showed the proposed method had good performances and it would be sufficiently use in the guide system for the people who are visually impaired.

This paper reports a noble instrument that helps physically disabled people to access computers. There have been numerous attempts to develop such a methodology, but most of them require an additional space for workstation often including access program installation. The additional space also needs to be carefully designed to consider each specific disabled area. This study aims to develop a system that removes the spacial limitation by putting the integrated computer interface using the wheelchair controller. The implementation of the computer workstation is performed by utilizing an USB interface. The developed equipment will take an important role to support various social lives for the users and eventually to improve their quality of life.

In this paper, an implantable middle ear hearing aids using an electromagnetic transducer which consists of a tiny coil and a magnet is designed, and objective design method to implement a vibrator of the electromagnetic type transducer is proposed. Sound characteristic of the electromagnetic type vibrator is excellent but power transfer rate is lower than that of a ceramic type. To improve power transfer efficiency of system, external and inner part of a middle ear system is designed using FI\T transmission method. We implemented an experimental set of the designed transducer, inner part, and outer part. Then, we measured vibration characteristics of a metal strip and a temporal bone of a dead body. As the results, we confirmed the advantage of FM method and showed that designed transducer could effectively transmit vibration of amplified input sound pressure to ossicle.

When the visually impaired walks inside a building like corridor, a GPS cannot be useful for the walker in estimating his or her position unlike the case of outdoor space. This paper presents two novel methods to measure the walking distance using a low cost camera worn on the chest of the visually impaired. In the first method we analyze the periodic variation of image focusing values. Walking steps are counted by checking the period tor the rough measure of the walking distance. The second method counts the step number by monitoring fixtures on the ceiling, which have a certain interval. Lamps on the ceiling appeared on the video are monitored in this paper. The T-S fuzzy theory is used to detect lamps, and the walking steps are estimated by the positional variation of the lamp due to the gait of the walker. The two methods are tested in real experiment, and the results are compared.

최근까지 개발되었던 청각 보조기 중에서 공기 전도형 보청기의 하울링 (howling) 현상과 수술 후 이소골 등 기존 음향계의 재생이 불가능한 인공 와우 (cochlear implant system)의 단점을 해결하고, 동시에 청음 명료도가 높은 음성 신호를 전달하기 위한 수단으로 연구된 것이 인공중이 (implantable middle ear hearing device) 이다. 본 연구에서는 인공중이의 음성 신호 재현을 위한 진동 장치인 차동전자 트랜스듀서 (differential electromagnetic transducer, DET)에 대한 수학적 모형화와 계의 진동을 기술하는 운동방정식을 유도하고 그 해를 구하였다. 제한된 크기와 인가 전류 $1\;mA_{rms}$ 정현파에서 최대 구동력을 얻기 위해서 전자기력에 대한 유한요소해석을 수행하였고, 결과에 의해서 자석과 코일에 대한 최적 크기를 결정하였다. 사람의 중이 내 등자뼈 (stapes)의 진동 특성과 유사한 진동을 갖는 DET를 설계하기 위해서, 진동막의 강성계수를 변화하면서 진동해석을 시뮬레이션 하였다. 설계된 DET는 마이크로 머시닝 기술에 의해서 제작하였고, 그 진동 특성을 측정 하였다. 최종적으로 측정된 진동 특성에 대한 분석을 통하여 인공중이를 위한 진동 장치로서의 적용 가능함을 확인하였다. Among various kinds of hearing aids which have been developed so far. the conventional air conduction hearing aids have some problems such as the acoustic distortion, an howling effect due to acoustic feedback. Another type of hearing aid. the cochlear implant system can be applied to the profound imparied person. However. it shows the disadvantage that there is no possibility of recovery of the acoustic organ such as ossicle. On the other hand. the implantable middle ear heaving device directly vibratos the ossicular chain and has better sound qualify. good cosmetics for appearance. and wide frequency responses so that it can overcome the defects or the conventional hearing aids. In this paper, a mathematical modeling and a momentum equation derivation of the DET has been performed. For the optimization of the structure dimension generating maximal vibrating force of the DET. the computer simulation using a finite element analysis (FEA) software has been performed. Also. the vibrating transducer has been designed to make the frequency characteristics or the transducer be similar to those of the normal middle ear. Through the experimental results, the measured vibration characteristics of the DET has been evaluated to verify the performance for the application to implantable middle ear hearing devices.

This study investigated Apple"s iOS and Google"s Android, the two most common mobile operating systems, in terms of the operating methods, OS-mounted machinery, applications, and the method for running their application stores, as well as Apple"s and Google"s services and contents and OS revenue models. It was found that iOS shows relatively closed management styles, compared with Android, but maintains a certain levels of quality and stability through the styles. Further, this study looked into the operating systems" accessibility requirements for persons with disabilities and aged persons. The results showed the OSs have implemented similar functions in terms of most typical accessibility requirements. From the findings was investigated the possibility for preparing an accessibility standard that integrates and unifies, regardless of the operating systems of devices, basic and essential components based on the common accessibility requirements of the two operating systems.
