In the ICT field, one among the remarkable issue of in 2014 is the "Wear computer", that is, the opening of "Wearable Device" age. The Samsung galaxy gear and products like Google glass and Apple watch are done as the wearable device. According to the definition of MIT Media Lab, the wearable device adheres to the body and is included till the application which names all things doing the computing action and can perform the partial computing function. And the wearable device is one brain. If the wearable device is popularized, it will be changed many things. First of all, 2 hands become free. My body is due to be connected to 24 hours Internet. It is not level that it adheres the Smart phone or device to the body and the brain role in which the device is connected outside directly, the human body is done. In this paper, the related companies analyze the technical elements of this wearable device especially.

In this Paper, we propose a Real-Time Localization Platform Built on WUSB (Wireless USB) over WBAN (Wireless Body Area Networks) protocol required for Wearable Computer systems. Proposed Real-Time Localization Platform Technique is executed on the basis of WUSB over WBAN protocol at each sensor node comprising peripherals of a wearable computer system. In the Platform, a WUSB host calculates the location of a receiving sensor node by using the difference between the times at which the sensor node received different WBAN beacon frames sent from the WUSB host. And the WUSB host interprets motion of the virtual object.

The advance of scientific technology is enhanced the effect of reaction. The trend of customer for high function product is enlarged. Thus, the composition of each industry, technology and product is actually happened. Therefore, the fusion of different fields in industrial design is widely accomplished. The example of this fusion effect is that 'ubiquitous or wearable computer' which is combined the function of cloth and computing, which is including any type, any purpose, any telecommunication and any multimedia of cloth inside. The ubiquitous or wearable computer will be a final thing of post pc or next step to pc and internet. This paper is studied for the research of smartware by assistance energy. In this paper, the development of multipurpose smartware(wearable computer) powered by solar energy is introduced.

A recent major development in computer technology is the advent of the wearable computer system that is based on human-centric interface technology trends and ubiquitous computing environments. Wearable computer systems can use the wireless universal serial bus (WUSB) that refers to USB technology that is merged with WiMedia PHY/MAC technical specifications. In this paper, we focus on an integrated system of the wireless USB over the wireless body area networks (WBAN) for wireless wearable computer systems supporting U-health services. To construct the WUSB over WBAN communication systems, we propose a WBAN beaconing structure to assign WUSB communication periods. In the proposed structure, WUSB uses private periods of WBAN. In our performance evaluations, we compare theoretical results and simulation results about throughputs of WUSB under various WBAN channel occupations to evaluate the effectiveness of proposed structure in WUSB over WBAN communications.

Maintaining a proper lookout activity routine is integral to preventing ship collision accidents caused by human errors. Various subjective measures such as interviewing, self-report diaries, and questionnaires have been widely used to monitor the lookout activity patterns of navigators. An objective measurement of a lookout activity pattern classification system is required to improve lookout performance evaluation in a real navigation setting. The purpose of this study was to develop an objective navigator lookout activity classification system using wearable accelerometers. In the training session, 90.4% accuracy was achieved in classifying five fundamental lookout activities. The developed model was then applied to predict real-lookout activity in the second session during an actual ship voyage. 86.9% agreement was attained between the directly observed activity and predicted activity. Based on these promising results, the proposed unobstructed wearable system is expected to objectively evaluate navigator lookout patterns to provide a better understanding of lookout performance.

Navigation system or way finding in Wearable computer help disabled and impaired persons and it is impossible to be safe and efficient for drivers as well as pedestrian. Wearable computing situation must be multi-tasking simultaneously and users need minimal attention. In this paper, we used virtual environment as real way-finding similarly. The direction cues of navigation system are investigated as visual only, visual & auditory, and visual & speech. In the paper, the trial demonstrates the difference of performance in detection of directing and performance of motor and subjective satisfaction of user.

In information society, Convergence was combined with a word 'digital'. Digital convergence means a service or new product which appeared through fusion of unit technologies in information and communication regions. The effects of convergence technologies and social phenomenons are visualized in overall regions of society such as economy, society, culture, etc. In this paper, we described a prospects and technologies needed in digital convergence environment. And we described a wearable computer which was leading case in digital convergence.

In this paper we propose wear-UCAM, which is a toolkit for context-aware application model in wearable computing. As the rapid developments of mobile technologies and relevant technologies, the interests in wearable computer also become indispensible in both academic and industrial fields. However, there are few research activities on the application framework or toolkit for wearable computing. Hence, we suggest wear-UCAM as the development toolkit for wearable computing applications, where we focus on how to collect relevant user context, manage it, and provide services based on the recognized context. The proposed wear-UCAM includes the abstraction of context processing as well as independence among sensors and services with other components. For the sake of rapid prototyping of the proposed toolkit, we utilize PDA with wireless LAN as a wearable computer. The detail explanation of the implementation and its discussion are presented in this paper.

WBAN (Wearable Body Area Network)는 옷이나 몸에 이식된 디바이스들이 몸을 중심으로 결합이나 통신하는 네트워크를 뜻한다. 여기서 사람이 몸에 착용하는 장치인 웨어러블 디바이스는 가벼운 형태의 배터리를 요구한다. 그로 인해, 다른 기기들과는 달리 짧은 배터리 수명을 가질 뿐만 아니라 통신에 관한 제약을 발생시킨다. 따라서 본 논문에서는 저전력 프로토콜을 지원하는 다중대역 웨어러블 디바이스 제어 시스템을 제안한다. 이를 위해 BLE (Bluetooth Low Energy) 기반의 프로토콜 스택으로 BLE, 6LoWPAN (IPv6 over Low power WPAN), CoAP (Constrained Application Protocol)을 적용해 데이터 패킷 크기를 감소 시키고 BLE/Wi-Fi 선택 기능을 통해 통신 제약을 완화하고 전체적인 WBAN 에서의 소비 전력을 감소하고자한다.

The convergence of IT technology and fashion is a marked trend in recent years induding sportswear, m-dress (mobile phone dress), and wearable computing. Despite continued research and record high development in the field, however, there still are unsettled issues like power supply, fit, washability and mobility when it comes to commercializing technological fashion product. In this context, this thesis is to propose feasible technology effectively applied to a portable bag. The first case is a bag designed to maximize sensitivity for a family who enjoys leisure activities often. The second one is a limited editionHaute Couture style bag targeting single women in their 20s and 30s. These two case studies are an attempt to demonstrate the possibility of applying wearable technology to a product design.
