In this paper, an accurate long-distance position measurement system using laser range finders (LRFs), which can be used for surveys in construction fields is proposed. Since the LRF is a sensor which can measure distance to surfaces of objects by radiating laser beams from itself and receiving the reflected ones, data obtained from the LRF are nothing more than the contours of objects. For this reason,...
Intelligent Space (iSpace) is a space which has ubiquitous sensory intelligence. In iSpace, positions of objects inside the space are one of the most basic information to implement various applications. This paper describes a method to localize the target objects using distributed laser range finders. Since data from a laser range finder is only distances and angles to object surfaces, we need to...
In this research, we propose a method to localize human hand position. In order to provide many types of services for human in the Intelligent Space, human observation is needed. Many applications, such as Spatial Memory, use human hand position for the indicator and to get hand position, the ultrasound localization system is used. When transceiver inclines, the accuracy decreases. To extend the function...
In this research, we aim to describe objects' properties for designing services of Intelligent Space. Intelligent Space is the environment that has distributed sensors for observing and actuators for acting in the space, in order to provide various services to human. In order to realize that, we focus on physical interaction between human and objects. Physical interaction between human and objects...
This paper describes an instruction display for learning Taijiquan (Tai Chi Chuan), a Chinese physical exercise, which is practiced chiefly in China and also in other countries of the world. Its practice is believed to promote and keep one's health but most learners may have difficulties in accurately practicing it because of the complexity of Taijiquan motions. The instruction display helps the learners...
