This article introduces developing trends of an 'Ubiquitous Interface' as an access method for use of various network resources, such as public wireless networks and un-licensed wireless networks in ubiquitous sensor network environments, without troublesome settings or operations by users. 'Ubiquitous Interface' is a relatively wide sense meaning not only physical interface of specified device or between processors, but anything method for access USN. These 'Ubiquitous Interface' able to provide seamless services that adapt autonomously to the user's movements and changes in the state of wireless resources. Recently, strongly recommended current technologies are RFID, NFC, Multi-mode mobile terminal, UMA mobile terminal and Wearable computer as a future ubiquitous interface. These technologies are have to have flexibility and multiple physical communication channels for seamless service hand over and serve easy connection at huge USN to user. Also, they have to must have flexible software structure. Finally, through the 'Ubiquitous Interface', we will be experience of seamless communication and realize a real liberty of communication.

These "Ubiquitous Interface" able to provide seamless services that adapt autonomously to the user's movements and changes in the state of wireless resources. Recently, strongly recommended candidates are RFID, NFC, Multi-mode mobile terminal, Wearable computer and OSGi for integrated digital home networking system as a future ubiquitous interface. These candidates are have to have flexibility and multiple physical communication channel for seamless service hand over and serve easy connection at huge USN to user. And, must have flexible software structure and multi-functional middleware. Consequently, for more enhance performance of an ubiquitous interface and developing, need more structured and integrated future plan.

Ubiquitous computing represents the most explicit attempt yet to move computing technology beyond the confines of tool usage towards a pervasive penetration of everyday life. In this report, as a general introduction of Ubiquitous computing, a trend of Ubiquitous computing devices is proposed for the applied technology fields and our everyday life. We outline a broad analysis of this technology based on a close examination of the researches advancing it. After introducing a framework for understanding modem device technology, we develop an interpretation of ubiquitous computing concentrating on its guiding principles, technological infrastructure, and trends.

As the digital environment gets ubiquitous, domestic and international research and development on smart clothing is being conducted actively these days. However, most research is being carried out with its center on upper garment. So research on lower garment is insufficient even though it affects wearer's activity and comfort to a great extent when digital devices are attached or wearers moves their body. Therefore, the type of clothes this research proposes is men's formal pants which have an electrically-vibrating wearable device. These are smart pants which are helpful in easing muscle pain with their massaging effect in daily life. For this purpose, this research intends to develop patterns considering the body shapes and movements of wearers and suggest a tentative structure plan for smart pants where a vibration device is attached, which is mainly composed of vibrating motor, controller, and switch, and considered their bulks, numbers, attaching places.

The implementation of home network systems In ubiquitous computing environments requires middleware that provides a method to control and operate home appliance devices. The Universal Plug and Play (UPnP), which is based on the IPv4 protocol and running on a PC, consists of UPnP devices that provide relevant services and control points that control the devices. However, It is inappropriate to Implement UPnP devices on a PC, since the implementation on a PC requires much space and electrical power. In this paper, a small embedded home network device equipped with UPnP middleware is implemented on an embedded GNU/Linux system running on an ARM9 platform, in order to deal with such problems.

The beginning of Web Services was understood as efficient technology for application integration in the internet, thus it was used to integrating the distributed enterprise applications or the e-business applications between partners. But, recently the usage trend of Web Services is largely spreaded out wireless network applications beyond the internet applications. The main reasons are that Web Services is the international standard of W3C, and Web Services is based on XML that is independent of the specific internal implementations such as platform, programming languages, communications networks etc. Currently Major company of Web Services such as MS, IBM, etc. focus on the research about technology for integrating various devices. In this paper, we define and explain technical issues for adapting web services to ubiquitous Environment.

Rapid development of high-micro device design and wireless mobile communication technique enables each information instrument and devices to form intelligent network. The discussion of ubiquitous computing that provide information when and where desired is advanced actively. Information collected through ubiquitous sensor network assists it will be able to provide a convenient and accurate service. In this paper, we design and implement system which shows in realtime through TFT/LCD display device sensing data transmitted in embedded system instead of host pc.

Recently, owing to miniaturization of computer and popularization of internet, ubiquitous computing is attracting considerable attention. In ubiquitous environment, user can receive desired information service anywhere, any time. With the advent of ubiquitous age through popularization of internet, it becomes important how to provide user with ubiquitous environment, and what and how to provide to user. In this paper, method to automatically select device most suitable for user in ubiquitous environment is offered. search agents search peripherals, make a list by function, and transmit to serve. Serve learn the transmitted information through intelligent system. If user input information in the form of linguistic according to the list, serve select device suitable for work environment, and compose the system through IP address. This was realize through practical example, experimented and confirmed.

Everyday, technology is evolved in many different disciplines. Computer and smart devices revolution take part of the evolved technology that continuously promising new features. Moreover, social networks services recently become widely popular, which most people in the world become a social-network-fond. In addition to the revolution of the evolved technology and social networks services, ubiquitousness is taking significant part in our daily lives. Although, there are many e-learning systems already existed, which use Internet technology along with a Web technology to provide education in various ways, in despite of that, there is no such existing system exploits the usefulness of smart devices along with the legacy of the online social networks besides the power of the ubiquitous computing technology. Therefore, we propose a smart device application, which fills the gap that has been missing in the recent contemporary era. It is an application that runs on smart devices particularly Smartphone devices; we call our system “Smart Device based Social E-learning System(SDES)”. We have preliminary implemented our system on Android OS. In this paper, we intentionally propose the system in order to ease the way people learn, to provide interactive accessibility in our system, and to utilize the advanced technology more wisely.

In this paper, we propose the integrated security management framework supporting the trust for the ubiquitous environments. The proposed framework provides the gathering and analysis of the security related information including the location of mobile device and then dynamically configures the security policy and adopts them. More specially, it supports the authentication and delegation service to support the trusted security management for the ubiquitous networks. This system also provides the visible management tools to give the convenient view for network administrator.
