u-learning (Ubiquitous Learning) 환경에서는 학습자들이 언제, 어디에서나 어떤 단말기로도 자유롭게 학습할 수 있는 학습자 중심의 교육과정이 가능해야 한다. 최근 각광을 받고 있는 태블릿 (Tablet) PC는 펜을 주로 입력 매개로 활용하고, 음성을 인식하여 이를 문자로 변환하여 저장할 수 있는 기능도 가지고 있어 초등교육 현장에 적합한 단말기이다. 또한 PBL (Problem-based Learning)은 학습자들이 자기주도적으로 문제를 해결해 가는 과정에서 문제해결력과 비판적 사고 기능을 신장시킬 수 있는 학습형태로 태블릿 PC 기반의 PBL 학습시스템은 u-learning 환경에서 학습자 중심의 교육과정 실현에 적합한 시스템이다. 본 연구에서는 태블릿 PC 기반의 PBL 학습시스템의 인터페이스 설계 방안을 제시해 보았다. 본 연구에서 제시하는 사용자 인터페이스의 특징은 다음과 같다. 첫째, 학습의 프로세스를 프로젝트의 목적 및 과제 파악 단계, 학습계획 수립단계, 자료의 수집 및 정리단계, 프로젝트 마무리 단계로 구분하고, 각 단계에서의 학습자의 활동을 지원하는 시스템으로 구성한다. 둘째, 태블릿 PC 기반에서의 학습 활동에 서투른 학습자도 직관적으로 접근 할 수 있도록 인터페이스에 아이콘을 적절하게 활용한다. 셋째, 태블릿 PC에 펜이나 음성으로 입력된 자료를 문자, 도형, 이미지로 손쉽게 저장하고 축적할 수 있도록 한다. 넷째, 학습자들간의 상호작용과 교사의 피드백을 손쉽게 할 수 있도록 게시판, 자료실, 통합 메시지함의 기능을 활성화한다.

In this paper, we present the results of educational innovation case study using U-Learning Box and Ubiquitous-based Test(UBT) system for 6 sample primary schools in Nepal. As Nepal is considered to be a developing country with electricity problem to the school, the U-Learning Box, consisting of a small and easy-to-use tablet PC for teacher and a small smart beam with its own battery was evaluated as the optimum solution to support continuous basic English and hygiene education for these schools. And UBT technology using tablet PC was used to evaluate and analyze basic English learning ability of the students, which helped us realized that it is necessary to improve the educational environment and develop suitable educational contents. We hope that the global educational innovation using U-Learning Box and UBT technology will become a successful model for global equality of educational opportunity project for developing countries including Nepal.

In the case of laptops and tablet PC's that replace desktop, it uses the Windows operating system to provide various functions depending on operating system dependency, the Windows operating system does not support real-time processing because it uses multi-level feedback queue scheduling that extends round-robin scheduling. Also, since the initial value of Local APIC Counter can not be obtained from the Windows 8, the real-time processing function provided through the existing RTiK does not work. In this paper, we calculate Local APIC Counter value by using MSR_FSB_FREQ register to support real-time processing function on tablet PC's. We designed and implemented RTiK+, which provides real-time processing function to guarantee the periodicity by calculating the operation time of accurate timer. In order to verify and evaluate the performance of the implemented the RTiK+, the period was measured by using the Read Time-Stamp Counter(RDTSC) instruction and it was confirmed that it operates normally at 1ms and 0.1ms period.

Industrial robots have been usually controlled using text-based programming languages provided by each manufacturer with its button-based TP(Teaching Pendent) terminal. Unfortunately, when we consider that people who manipulate TPs in manufacturing sites are mostly unskilled with no background knowledge about computer programming, these text-based programming languages using button-based interaction on manufacturing sites are too difficult for them to learn and use. In order to overcome the weaknesses of the text-based programming language, we propose a visual programming language that can be easily used on gesture-enabled devices. Especially, in our visual programming environment, each command is represented as a block and robots are controlled by stacking those blocks using drag-and-drop gestures, which is easily learnable even by beginners. In this paper, we utilize a widely-spread device, Tablet PC as the gesture-enabled TP. Considering that Tablet PC has limited display space in contrast to PC environments, we designed different kinds of sets of command blocks and conducted user tests. Based on the experiment results, we propose an effective set of command blocks for Tablet PC environment.

Objective: The aim of this study is to investigate the performance and usability of ten-finger text entry on Tablet PCs. Background: Generally a soft keyboard is used on Tablet PCs. However, the soft keyboard's performance is usually worse than physical keyboard's performance. In this study, we proposed a modified keyboard for tablet PCs to improve the performance of ten-finger text entry and evaluated the performance and subjective ratings of the keyboard. Method: The modified soft keyboard that is suggested in this study was compared with current Google and Samsung soft keyboards on Tablet PCs. Results: The three keyboards were not significantly different in terms of typing speed, error rate, and mental workload and showed bad performance. Also, the subjective ratings were not shown positively. Conclusion: Based on our results, ten-finger text entry using soft keyboards on Tablet PCs seems to be very difficult. However, we need to research the possibility continuously since ten-finger text entry can improve typing speed. Application: Our study can be a starting point of research that explores ten-finger text entry on Tablet PCs. The new soft keyboard design can be one of the soft keyboard alternatives. However, the key factors to improve the performance and usability of the soft keyboard will not be 'key size' or 'convenience to typing special characters or numbers', but other factors (e.g., 'tactile feedback').

As we move into the aging society, social efforts to improve the IADL of the elderly are getting bigger. In this study, elderly people were taught using tablet PC - based contents in order to make ATM more convenient. The ATM contents used are the educational contents for the tablet PC developed in the same way as the ATM interface used in the actual bank. After the elderly used the content, they evaluated the usability of the content.

Comics is sequential art. In comics, the story is developped by its sequential panels which have their own sizes and sites. Accordingly, comics is closer to 'space' art than text. The reading order in a page of comic book follows the human long-standing reading habit, and it is the same as that of textbook. When we read a korean comic book, our eyes run from left to right, and downward on the page. But some factors related to panels or comic structures can change the typical reading order. Meanwhile, breaking the typical reading order is easier in the "infinite canvas" by reason of unconstrained spatial composition. This paper introduces the factors that change the comic book readers' reading order and proposes a tablet PC comic book layout which includes an arbitrary reading path using interaction

The purpose for installation of offshore weather station is a measurement of wind resources and so on. If weather station is operated, it will be possible to analysis for wind resource and arrangement of wind farm by using measured data. In this paper, we carried out the development of offshore wind resource measurement system for measuring offshore wind resource. Also, In order to monitor for real-time wind data with 1 Hz, we installed the wireless transmission system. All wind characteristic data are sent to the server PC through the this system is connected outport of DataLogger. Transmitted wind data were used in order to look at in the Web-page and tablet PC on a real time basis in a graph. In this paper, we will introduce about the wind resource measurement and remote monitoring system that is the result of study.
