현대의 PC 환경에서 사용자 인터페이스의 변화는 계속하여 발전할 것으로 기대된다. HCI 전용 인터페이스는 종래의 CLI; Command Line Interface의 시대에서 MS-Windows 기반의 Graphic User Interface의 시대로 전환되어 왔으며, 가까운 미래에는 NUI; Natural User Interface의 시대로 도래함은 부정할 수 없는 현실이다. 미래에는 전통적인 표준 입력 장치인 키보드, 마우스를 탈피하여 새로운 개념의 입력 장치들이 개발되고, 터치 방식과 같이 인간의 직관적 인지능력을 흉내 낸 인터페이스로 발전할 것이다. 본 논문에서는 NUI의 사례 연구로서 닌텐도 WiiRemote를 Bluetooth와 함께 PC에 연동하여 차세대 인터페이스인 PC Controller를 설계, 사람 제스처를 통한 자연스런 한글입력의 가능성을 제안한다.

In this paper, we have designed and implemented the RAID controller board which connects to the host computer with serial ATA interface and connects to the disks with parallel ATA interface. Serial ATA interface is proposed to overcome the design limitation of parallel ATA while enabling the storage interface to scale with the slowing media rate demands for PC platforms. Serial ATA is to replace parallel ATA with the compatibility with existing operating systems and drivers, adding performance headroom for years to come. It Moreover, serial ATA provides even faster transfer rate of 150 Mbytes/s which is larger than that of current parallel ATA. The RAID controller board designed in this paper combines up to 4 disks with parallel ATA interface, and connects to PC host computer with serial ATA interface. We have implemented RAID controller using Verilog HDL language with FPGA chip. The RAID controller supports RAID level 0 and 1 functionality. Experimently, the average read/write performance of parallel ATA interface is about 30 Mbytes/s. Therefore, when 4 parallel disks is connected to the RAID controller board, we can get almost full throughput of serial ATA protocol using the RAID level 0 configuration with 4 disks.

The music education improves the creative talent, social skills and academic achievement of the students. For the efficient music education, the learner centered study is highly recommended rather than the passive education, which supports self-control in selecting teaching materials, learning patterns and speed. For the successful self learning, it is requested to develop the collaborative educational learning tools, especially electronic collaborators such as H/W and S/W. Though there exist many commercialized electronic instruments and the PC MIDI based softwares, these tools have some limits and problems for the primary student to learn playing the musical instrument by himself. In this paper, we propose a supporting tool implementation method using an electronic keyboard instrument with USB Interface and PC-based software to help the primary student to learn playing the musical instrument. We implemented an electronic keyboard instrument module compactly and at low cost using a PIC18F4550 MCU. PC based software was developed to edit musical score, process the MIDI information, and interact with the electronic keyboard instrument module. This tool can offer a similar keyboard instrument environment and can be incorporated with self learning contents.

Poly(alkyl acrylate-g-caprolactone) graft copolymers were prepared, and they were applied as compatibilizing agents for polycarbonate (PC) / poly(acrylonitrile-butadiene-styrene) (ABS) blends. The incompatible poly(alkyl acrylate) segment was incorporated into the graft copolymer in order to localize the copolymer at the PC/ABS interface. The blend containing 1 phr of the copolymer showed remarkable improvement in impact strength as well as in elongation at break. Impact improvement was more pronounced with a thinner test specimens of 1/8 inch thickness. Morphological study showed that the presence of the graft copolymer led to a smoother PC/ABS interface due to the interfacial enrichment of the graft copolymer.

We will report a few methods to improve the efficiency and stability in small molecule based organic solar cells, including the formation of bulk heterojunctions (BHJs) through alternative thermal deposition (ATD), the use of a micro-cavity structure and interface modifications. By ATD which is a simple modification of conventional thermal evaporation, the thicknesses of alternative donor and acceptor layers were precisely controlled down to 0.1 nm, which is critical to form BHJs. The formation of a BHJ in copper(II) phthalocyanine (CuPc) and fullerene (C60) systems was confirmed by AFM, GISAXS and absorption measurements. From analysis of the data, we found that the CuPc|C60 films fabricated by ATD were composed of the nanometer sized disk shaped CuPc nano grains and aggregated C60, which explains the phase separation of CuPc and C60. On the other hand, the co-deposited CuPc:C60 films did not show the existence of separated CuPc nano grains in the CuPc:C60 matrix. The OPV cells fabricated using the ATD method showed significantly enhanced power conversion efficiency compared to the co-deposited OPV cells under a same composition [1]. We will also present by numerical simulation that adoption of microcavity structure in the planar heterojunction can improve the short circuit current in single and tandem OSCs [2]. Interface modifications also allowed us to achieve high efficiency and high stability OSCs.

A combined PC and TV monitor has been developed in several companies. The characteristics of physical user interface in this monitor are likely to vary from existing monitors. Therefore, two experiments to investigate the physical interface characteristics of this monitor were conducted. The first experiment was to investigate the characteristics of color perception with monitor coating (coating vs. non-coating) and screen brightness (30fL vs. 35fL) in the PC mode. The second experiment was to investigate the characteristics of luminance contrast with monitor coating and image movement (static vs. dynamic) in the TV mode. Twenty-three subjects (male 12, female 11) were participated in this experiment. In the first experiment, average color temperatures were obtained in all experimental conditions. There was a significant difference between coating and non-coating screen at 0.1 level. In the second experiment, average luminance contrasts were obtained in all experimental conditions. There was a significant difference between coating and non-coating screen at 0.05 level. In addition, there was a significant difference between static picture and dynamic picture at 0.1 level.

In this paper, we propose a system which easily controls the existing serially connected multi-channel speakers in a general personal computer by using a USB(Universal Serial Bus) interface. The personal computer as a host of the USB interface analyzes a sound source and sends audio data in a real-time fashion by the use of the isochronous transmission, one of four transmission methods provided by the USB interface. In addition, a channel is assigned by means of the bulk transmission, one of four transmission methods provided by the USB interface. Transmitted data from the USB host are sent to each speaker through compression and packet generation process. Each speaker detects corresponding digital data and regenerates audio signals through DAC(Digital-to-Analog Converter). A user can easily select a sound source file and a channel by the use of a GUI environment in a personal computer.

This paper shows the basic configuration for the system(H/W and S/W) which can interface between the PC and the slave robot. The PC(personal computer) is used for the basic MMI(Man-Machine Interface) system. The slave robot is controlled through the PC, actually the generated trajectory by using polynomials. The velocity control is carried out at the via points of the rrajectory. The heuristic method which chooses the average of the two slopes as the via velocity is used for the velocity control. From the simulation results, we can choose the better trajectory polyomial for reducing the deviation error at the starting and arriving parts.
