- As multi-media units are well developed recently, navigation kits with GPS functions are utilized and on-line map services provide information in advance. Thus, we can say that ways of using maps are more and more convenient as technology develops, and the time users need to spend looking for information is getting shortened. This study aims to offer location information and local information connecting mobile devices and PCs each other for users who visit a specific area. And Key feature of this research lies in the proposal of methods for offering much information to users through the connection of the two devices and on-and-off lines by using a network in real physical space and integrating and extending the sphere of information.
This study aims to offer location information and local information via mobile devices and PCs for users who visit a specific area. Currently, the service is being offered via mobile devices and PCs; however, the difference with this study lies in the proposal of methods for offering much information to users through the connection of the two devices and on-and-off lines by using a network in real physical space and integrating and extending the sphere of information.
II. STUDY METHOD
It mainly means a PDA, but it means all mobile terminals including mobile phones and PMPs, and it is aimed at terminals supporting a sensor that can detect the location of the user in any form. • Ubiquitous-based tour guide system of Nara area in Japan
It provides tour information by reading a U-code from an IC tag and a wireless marker installed within a specific area with a PDA. It offers a road guide, an introduction in various languages, route navigation, tour information, nearby area information, and also other information by utilizing a GPS.
It means a home or office PC that is not portable and is subject to spatial limitations in general, and the aim is for map-based contents serviced on-line. • Cyworld (map.cyworld.nate.com)
It is a service shared with other members by combining listings of mini home pages or paper uploaded with personal experiences with location information of a map.
It connects the episodes and picture information of other people who have already visited a specific space with location information of the map in a form of a chat box.
The study reviewed the current ubiquitous-based infrastructure and extracted several important key words about the characteristics and strengths of each device through a case analysis of a guide system using a PDA and a PC-based on-line map service as examples of service cases aimed at the two devices.
[ Figure 1: Research Process ]
Ahead of this study, the study collected information through a research survey and user behavior research, and information architecture was organized based on the analysis results. The vehicles of the study were classified as mobile devices and PCs. The characteristics of each media include the following.
It is possible to recognize the location of a user with the development of location-based location identification technology (Zigbee, RFID, and IR) and coordinates-based location identification technology (LBS and GPS). • Extension of space: Detects a location with a ubiquitous sensor for both outdoor and indoor space • Mobility: Is portable and may be connected wherever it can be connected to a network. • Combination of on-and-off line contents: Creates an environment so that a visitor’s experience may be continued on-line by promoting an on-line exhibition hall and community. d. Multi-media support: Automatic video, voice guide
With the distribution of digital cameras and mobile phone cameras, it is possible to take a picture and videotape anywhere, and as the web becomes easier it is possible to upload and share video files easily on the web. The features of a blog may be as follows. • Extension of User-Oriented Participation With the influence of UCC (User Created Contents), share rich contents (article, picture, video, frequent visit, and map). • User Experience Information It is possible to obtain various user experience information for a specific space.
The study conducted a comparative analysis of the features and differences between mobile devices and PC devices supporting a digital map.
Since a desk top computer has a large space for saving information and is available for managing files, it is appropriate for a blog system that uses a map, and a mobile device is suitable for utilizing navigation that employs mobility and LBS or GIS.
When making a development in connection with this, it is necessary to prepare mutually different design strategies in consideration of the different features of the devices,
Through a case study it was determined that it is possible to deduce the significant features and pattern of a map service as three factors. The map service could be divided largely into three including route search, transportation line, and user experience service; and on a PC users offer and share sensible information such as recommendable foods and recommendable places based on their experiences, which is closely related to reality, upon their participation.

Analyzes an information factor offered on the screen by an internet map service focusing on a specific area, and utilizes it as an information structure for preparing a prototype.
[Figure 2: Research Concept
This study analyzed the features by device type through a case study, and it was found that the interface between devices, manipulation features, and user environment are quite different. Furthermore, the study deduced the features of each service and information factors for preparing two types of prototype.
If features between and the strengths of the two devices may be utilized, it would be possible to offer much more information and services to users. Conditions and matters to consider for this may include the following.
• Unification of identification code such as a information Factors and pictogram • Securing of connection network such as network and communication
• Same type of digital map support between the two devices • Maintenance of consistency of information structure despite the difference of interaction (manipulation method) and display size
C. Service for information connection between the two devices with the use of a network • Route storing visited by users • Transfer of picture taken or voice recorded at a traveling site on-line along with the location information of the current user, and save it to the blog • Nearby restaurant location search and on-line reservation • Offer of personalized service
As contents become diverse and information is delivered in real-time, the way of information exchange between the two mediums for utilizing such information will become diverse.
It is necessary to pursue much more research into the method of connectivity between on-and-off line media for accepting such a change. Also, it is necessary to develop a design concept for users through a user survey that observes user behavior in reading an actual map at the stage prior to prototype development.
