스크린리더는 그 특성상 모든 응용 프로그램을 지원해야 함에도, 타 응용 프로그램의 빈번한 업그레이드 와 스크린리더 개발 인력 부족 등의 이유로 시각장애인들이 자주 쓰는 소수의 응용 프로그램만을 지원하는 것이 현실이다. 본 논문에서는 스크린리더의 개발 생산성을 높일 수 있는 방안으로 개방형 API 를 제안한다. 스크린리더에 개방형 API 를 채택하고 이를 공개함으로써 스크린리더 개발 업체는 주엔진 모듈의 성능 향상에 모든 인력을 투입하여 성능 좋은 스크린리더을 개발할 수 있을 것이며, 프로그램 개발이 가능한 사용자나 자원봉사자들이 개방형 API 에 맞도록 응용 프로그램 지원 모듈을 플러그인 형태로 개발할 수 있을 것이다. 이를 통해 국내에서도 다양한 응용 프로그램을 지원하는 우수한 스크린리더를 개발할 수 있을 것이다.

The purpose of this study is to evaluate the accessibility of the Cakewalk TTS-1 for the screen reader users. An evaluation was performed by testing the accessibility of a editing virtual instrument that is a part of MIDI production based on the NCS(National Competency Standards) by using the TTS-1 and the Sense Reader. The results of this study are as follows. The TTS-1 itself can't provide enough accessibility for the screen users to do an above task. But the screen reader users can perform the above tasks if they use extended access functions like Sense Reader's Mouse Pointer function, Position Memory function and MIDI Control Signal function. Even if they use the extended access function, there are functions that is difficult to access. To solve this problem, several suggestions are proposed.

The purpose of this study is to evaluate the accessibility of the Cakewalk SI-Drum for the screen reader users. An evaluation was performed by testing the accessibility of the [Virtual Instrument Editing] that is a part of MIDI Production of the NCS(National Competency Standards) by using the SI-Drum and the Sense Reader. The results of this study are as follows. The SI-Drum has almost no basic accessibility for the screen users to do an above task. But the screen reader users can perform the tasks by using Sense Reader's Mouse Pointer function and Position Memory function. To use SI-Drum more efficiently, SI-Drum's basic accessibility have to be provided fully. Several suggestions are proposed to develop a fully accessible SI-Drum for the screen users.

The user interfaces of electronic-book (e-book) readers in the e-book market are highly diverse, and this has led to major usability issues. In this paper, we analyze user preferences in terms of feature-setting options and the use of touchscreen actions in the six most commonly used e-book readers for smartphnoes. We identify alternatives for these features, which can enhance the usability of e-book readers, based on these user preferences. The survey results for the feature-setting options show that it is desirable to support at least eight background colors, as well as the ability to specify the color of the background icons. Adjusting the screen brightness using a setting bar with the support of an auto-brightness option is desirable, as in using +/- buttons to adjust the font size, as well as approximately 10 font faces. We find that it is desirable to support fade, slide, scroll and curl page-turing options, in addition to a simple non-animated page-turning effect, and that page movement should be accomplished using a scroll bar with the support of the page movement features by entering a page number, and by using the table of contents as well as bookmarks. The survey results on the use of touchscreen options indicated that it is useful to be able to configure the screen layout of an e-book reader by dividing it into three areas: left, right, and center. And then, when users briefly touch the left and right areas, it is ideal to move to the previous and subsequent pages, respectively; and when they briefly touch the center region, it is desirable to display a touch feature menu. We believe that the results of this study may provide guidance in the design of user interfaces for e-book readers.

The purpose of this study is to evaluate the accessibility of the SI-Bass Guitar for the visually impaired who uses the Sense Reader which is a screen reader software. An evaluation was performed for the Sense Reader users to do the [Virtual Instrument Editing] task on the NCS(National Competency Standards) using the SI-Bass Guitar. This study shows that the SI-Bass Guitar has no basic accessibility. But the visually impaired can do above task using the Sense Reader's Mouse Pointer and Position Memory Function. Several Propositions are suggested to develop a fully accessible SI-Bass Guitar for the screen users.

This paper proposes methods of evaluating and measuring accessibility of accredited certificate subscriber software which is one of crucial applications to submit personal certifications while web surfing. The presented methodology is to evaluate accessibility by using a certain assessment tool and is to normalize accessibility level into points, so that the software developers who are unfamiliar to screen readers can easily perform accessibility evaluation. The software from the major 78 organizations has went through the assessment. Those of 48 organizations, 62% out of the total, have acquired less than 70 points, implying the software of them is not accessible by the blind. The remaining 18 software got the highest point(88), are partly inaccessible by the blind that uses screen readers. This implies that the proposed methods are applicable to evaluate the accessibility of the software.

In this paper, the implementation of a production control system based on RFID has been studied in order to obtain an exact Cost Center data such as the name of workers included a process of work and a time period to finish the process. The cost center of a worker will be correctly obtained by checking the work time using RFID tag data and by transmitting the data to a server of ERP or POP system. And also warming up time, cleaning time, power failure, and out of order sign will be checked and calculated using the data stored in RFID tags attached in workers and machine facilities. Therefore, exact Cost Center data will be obtained by the production control system with touch screens entering the data according to the situation in real time.

The purpose of this study was to evaluate the maximum and optimal listening speed of Korean TTS for the blind. Five blind participants took part in this study. The instruments used in this study were 17 sentence sets (2 sets for an excercise, 10 sets for a repeated test, and 5 sets for a random test), with short meaningful sentences (the same sentences for the repeated test, different sentences for the random test) with 15 differentiated speeds (Range=0.8-3.6, SD=0.2). Each participant's maximum and quickest listening speeds were calculated by objective recall accuracy (determined by the number of correctly recalled syllables/the total number of syllables in a sentence X 100) and subjective recall accuracy (recall accuracy judged by each participant's subjective evaluation). The results showed that the participants' recall accuracy had a tendency to increase as the TTS speed decreased. Participants' subjective recall accuracy was higher than objective recall accuracy in the repeated tests and vice versa in the random tests. The results also revealed that the participants' sentence familiarity had an influence on their Korean TTS listening speed.

This research intended to identify empirical recommendations for designing the DAISY service interface and used a case-based method. The case of this research was LG Digital Talking Book Library(http://voice.lg.or.kr) of LG Sangnam Library. A group of experts evaluated the current DAISY interface serviced by the web. After evaluation, major recommendations were suggested and these recommendations were used to develop the new DAISY Interface. Major recommendations were consideration of the reading flow of the screen-reader program, prevention of perception as an error about the time delay, development of web-based software, support for convenient functions and prevention of shortcut key overlap and so on.
