In recent years, the embedded devices are very popular, and the smart phone and Tablet PC are the most important consumer electronic products. When programmers design a program on PC, there are a lot of resources can be used to enhance the performance of the program. But the resources on embedded devices are limited. Thus, how to profile and optimize the programs on embedded system becomes an important...
Recently, people pay more attention to healthy living conditions. Such changing lifestyle leads to demand for wearable health monitoring, new medical technology, healthy food and clean air. Thus, indoor air monitoring and control will be an emerging industry with a huge market size. In this paper, we have developed an indoor air monitoring system with ability to observe volatile contaminants, especially...
In this paper, a household electric appliance remote controller operated without touching it is proposed. A prototype was prepared in order to evaluate the effectiveness of the proposed method.
Recently, sitting posture monitoring has been focused in the fields of health management in order to improve the quality of Sedentary Lifestyle. We propose an unconstraint sitting posture monitoring method using a sensitive cushion based on hetero-core fiber optics. The hetero-core fiber optic sensor has several advantages for unconstrained human behavior monitoring such as single-mode transmission...
This research aims to propose a supporting system with sensor network technology and cleaning robots to alleviate workload of caregivers in welfare facilities. Our focus is to reduce the labor load of nurses that has increased with elderly population growth. On the basis of the system requirements clarified from a site survey in a nursing facility, this paper proposes an integration method of sensors...
Because of the accident of falling out of the bed of inpatients / recipients of care occurs constantly in nursing /care facilities, the technique of roll-over detection / posture state estimation are required. In this paper, we developed the detection technique of roll-over with the thermographic watching system with the respect of a person's privacy The detection of roll-over is the method which...
It is important to assess blood vessel conditions of our daily life. We, therefore, developed a reasonable healthcare monitoring system with pulse wave analysis. Filter circuits were carefully designed to carry out the detailed pulse wave analysis, considering a possibility of smartphone or tablet applications. The proposed analyzer can predict arterial states and stiffness. The healthcare system...
In this paper, we present a home sleep care system to monitor function of activity measurement and sleeping position estimation via vision-based algorithms. The outcomes are integrated in a telecare middleware with a hierarchical software stack and visualized by a structural subsystem. Since smart TVs play an important role in home tele-healthcare system, we centralize and display additional sleep...
The objective of this paper is to evaluate pilots' body and physiological performance during their works using a large model sensor (tri-axial accelerometer and atmospheric pressure sensor) and a heart rate monitor toward safe harbors. The dis/embarkation experiment is carried out for the real pilotage. The results show that the largest acceleration 1.5–2.0 G appears during transfer from a pilot ladder...
To provide a navigational tool to show a building's interior and other related information, we propose a three-dimensional computer graphics (3DCG) display system connected to the elevator's movements that can present a building's structural information. We altered the 3DCG's viewpoint according to the detected acceleration rate of the elevator and compared perceived acceleration rates through somatosensation...
This paper presents Virtual Drum. Virtual Drum allows us to play a drum anytime, anywhere by monitoring the player's body movement with Microsoft Kinect, and presenting a virtual drum projected by a small projector on any surface near the player. The colors, shapes, and sounds of drums can be changed by the player's gesture during his/her play. This approach increases the playfulness of the drum play...
Educational games mostly target children, often neglecting adults. To find out if adults are interested in educational games, we created and displayed one in an exhibition and used it to collect and study the audience's feedback and reactions toward such games. At the end of the experiment we found out that adult's interest in educational games changes depending on their age, and that they the will...
