This article presents a method of generating grid maps for autonomous navigation using a geographic information system (GIS). Besides developing ordinary map systems, a GIS can be applicable to the terrain trafficability analysis for an unmanned ground vehicle (UGV) by generating maps in which information about its spatial environment is encoded for path planning as part of autonomous navigation....
This paper classifies the user's purchase pattern into four types of behavior, and proposes an agent-based personalized multimedia Jukebox that provides a personalized service on the client side. The proposed Jukebox assists the efficient management of numerous multimedia contents stored in a personal desktop computer, and provides personalized multimedia contents to the mobile device based on a push...
Ubiquitous computing enhances computer use by making many computers available throughout the physical environment, while making them effectively invisible to the user. Invisible devices and software are connected to one another to provide convenient services to users. In this environment, users want to get a variety of services by using only an individual mobile device which has limitations such as...
In this paper, we present an agent-based personalized Web service system in music web page. In computing the preference, we develop the recommendation algorithm using the ratio of the length of each web page and users' staying time on it.
In ubiquitous environments, users want to get a variety of services using only their individual mobile devices, but their devices usually have limited resources. Many resources in ubiquitous environments can be available and users want to share such resources. Therefore, resource sharing in a ubiquitous space and its efficient processing is one of the new research topics. However, the users' situations...
In ubiquitous environments, user wants to get a variety of services using only his individual device. For this requirement, resource sharing and its efficient processing is one of the new research topics. However, the situations of each user are different and user preferences also are various even if user environments are the same. Therefore, although users want to get the same service in the same...
In ubiquitous environments, invisible devices and software are connected to one another to provide convenient services to users. In order to provide such services, we must have mobile devices that connect users and services. However, the types of services available have thus far been limited due to the limited resources of mobile devices. This paper will propose a solution to the resource problem...
