Mobile computers can process large amounts of data at high speeds, and it is feasible and easy to implement a remote monitoring system utilizing mobile computers. Because of their portability and convenience, these computers have been employed in various research areas to develop such monitoring systems. Existing monitoring system is a bit difficult to real time monitoring the scattered offshore facilities. So this paper compensate the existing system by using mobile computers such as a tablet PC-based monitoring system. Also, the scattered offshore facilities can be monitored in real-time through the tablet PC. The developed monitoring system is a fully Internet-based monitoring platform that enables one to monitor and control remote oceanic applications at any time and any place where it is possible to access the Internet. It can be applied to many oceanic applications as well as the unmanned systems and remote monitoring systems on land.

Pen-based interaction is universally available on smart devices and especially on Tablet PCs. Previous studies compared various input methods like fingers, a mouse or a stylus pen on PCs or on a touchscreen based devices such as smart phones. At the same time, various soft keyboard applications are being developed on application stores of smart devices. However, these previous studies did not suggest which one is a suitable keyboard application for Tablet PCs when users perform a certain interaction as input type. In this study, we compared two types of input methods (finger and pen) and three types of soft keyboard applications (QWERTY, Gesture and Swype) in a Tablet PC using performance measurements (accuracy and input speed) and discussed what types of applications showed better performance with each interaction on tablet PC. From these results, recommendations for the keyboard types depending on the input methods on tablet PCs were developed.

There are a variety of alternative products in the computer markets. A tablet PC, which is a small type of computer, is expanding its market share as an independent type of computer products. The purpose of this study is to find out what the factors are that led to the success of the tablet PC. A research study was carried out on the intention to use of tablet PCs by consumers. The factors that affect the intention to use of tablet PCs users were structured on the basis of attitude theory. According to the one-dimensional theory of attitude, cognitive factors affect the affective factors, which in turn affect conative factors. In the study, the relations between each dimension were set up. The hypothesis was tested by structural equation modeling. The test results are as follows. First, the values and satisfaction that the owners of tablet PCs feel from the products and the positive comments on the products from their nearby acquaintances affect in a positive way how much they like their products. Second, the products surrounding the tablet PCs did not affect the intention to use of the products. Third, the product favorability that the owners of tablet PCs feel affects the intention to use in a meaningful way. The results of the research also show that hi-tech products such as tablet PCs affect their attitude after they buy and use the products. This attitude affects intention to use of the products. The managers of companies that produce hi-tech products should consider the cognitive and affective aspects of the product owners when manufacturing and marketing products.

Generally in case of tablet PC's, the Windows 8 is used to support various functions or development convenience, however it cannot support real-time processing. In addition, existing commercial solutions and RTiK has a problem to support real-time processing due to impossibility of getting APIC timer count value which is used to generate timer interrupt separated from that of Windows. Thus, in this paper, we set the initial APIC count value using MSR_FSB_FREQ to support real-time processing on the Windows 8-based tablet PC's. Additionally, we deal with designing and implementing RTiK+ providing real-time processing to guarantee interrupt periods by controlling C-State which is used for low power techniques. To evaluate the performance of the proposed RTiK+, we measured the periods of generated real-time threads using RDTSC instructions which return the number of CPU clock ticks, and verified that RTiK+ operates correctly within the error ranges of 1ms.
