In this research, the authors aimed to mining Life logs for developing a user model-based service application. Life logs can be constructed by analyzing Motion logs, which are obtained from questionnaires, or motion data collected from sensors. And the user models, which help applications to provide appropriate service, can be constructed by mining these Life logs.
This research presents a system that provides useful information by data mining. The system collects human motions to process data mining, and uses the result to detect human intention, and then provide service. The system includes three parts: the input devices part that is to collect data, the server part that is to analyze and process the data mining, and the client part that is to provide service...
This paper presents an observation system of human-object interaction in the intelligent space (iSpace). Object information is necessary to describe events and human activities which happen in environments. Especially, names, colors, size and shapes of objects can be described manually because we can consider that the information will not change. On the other hand, information such as locations of...
In this paper, we will present an improved system which observes human activities. We have tried to describe the activities by objects usage because there are so many kinds of objects in environments and people use them to accomplish their activities. Therefore, by observing objects we can extract more information about activities of human and this may help us to estimate what people are doing in...
The differential driven two-wheeled inverted pendulum mobile robot has advantage of high maneuverability, which can maintain the balance on slopes and rough terrain and can pivot around a the central axis of its body in narrow spaces. It can be used to carry human beings as well as other goods. This paper studies the method of path planning for this robot in the known environments. The path planner...
In many surveillance applications, there are different properties of the environment to check. For example, in the case of robots surveilling an industrial depot, one could be interested in verifying for fire alarms, intrusion alarms or bio-hazards. It is very hard to characterize the solution of this problem in terms of a unique utility function. Indeed, this would require to define a measure of...
