Smart technologies promise to increase the quality of living and life - especially for elderly and impaired people. Following the “Smart City” paradigm, new challenges arise to increase the attractiveness of a residential district. This paper analyses driving and inhibiting factors in Smart Districts by a case study focusing the ageing society. It turns out that Natural User Interfaces can be seen...
This paper assesses influence of QoS degradation caused by 6to4 and IPsec on QoE of Web services by experiment. Since utilization of 6to4 and IPsec requires some overheads, QoS degradation caused by them is inevitable. The degradation can also deteriorate QoE of the Web service, but the affect of the degradation has not been clarified. From the experimental results, the authors confirm QoS degradation...
This paper empirically studies clarification of complex relationships between hierarchical QoS and QoE for Web services with the method using the path analysis. In the experiment, the authors treat three Web services and consider 10 parameters of three-layered QoS and four QoE parameters; they suggest a new model for a path diagram. The obtained path diagrams give high goodness-of-fit, 0.916, 0.915,...
This paper studies an effect of utilization of Multi-Path TCP (MPTCP) on QoE for Web services. The authors consider the Web usability as QoE and assess it by experiments with subjects; they compare the results of MPTCP with those of TCP. The experimental results show the followings. Indeed the utilization of MPTCP can provide higher QoS of the target Webservices than that of TCP, but it does not always...
Smart homes are driven by heterogeneity in nature and consist of diverse components that promote user comfort and security. In recent times, tremendous growth of Internet of Things (IoTs) applications is seen in smart homes. The huge diversity of various IoTs applications generally leads to interoperability requirements that need to be fulfilled. Current IoTs management is achieved using physical...
Human body communication (HBC) is expected to become a unique man-machine interface because the transmission path is established only when the user touches the target device. In this study, HBC between a stationary device and a wearable device worn on the wrist was investigated. Transmission characteristics between the devices and electric field around the human body model were calculated by electromagnetic...
This paper presents the design and implementation of a multi-standard energy management system, which leverages heterogeneous devices to convert existing buildings into Smart Buildings. Its main purpose is to increase the energy efficiency of buildings providing user awareness to promote green behaviors. The proposed solution has been designed to enable interoperability across different standards...
In this paper, we describe a prototype human head tracking parametric speaker system that can present speech in a highly directional beam. This system is composed of the Kobuki robot platform, the Kinect sensor, a USB-controlled camera pod and a parametric speaker. We found that it is possible to track and deliver speech to a human walking at an average speed of 5 km/h. Experimental results have shown...
Recently, investigations on user-oriented information delivery system to support information acquisition has been actively conducted. In order to provide information retrieved from the internet, TV program and local contents, we propose an information delivery system based on Active Information Resource (AIR). This paper describes a design of AIR-based cooperation mechanism of heterogeneous contents...
Learning character balance is important in calligraphy. Transcription is the practice method for learning characters, however it has some problems, for example, it is hard to judge intuitively whether character balance is correct, because the sheet of white paper and the sample image are separate. Therefore, the goal of our study is the construction of a support system for learning character balance...
This paper proposes an autonomous flying projector (AFP) that projects images from a micro aerial vehicle (MAV) on which a small projector is placed. The AFP works as a public and ubiquitous display, and has a potential for an expansion of projector applications (e.g., a digital signage moving in response to a distribution state of people, and the one following moving targets such as a person and...
Dementia is one of the most serious problems in aging society. Aerobic exercise has good evidence for its prevention. Walking and cycling are popular and practical aerobic exercises. However, elderly people have problems in the walking and cycling, which come from lacks of physical / mental functionalities and unsuitable traffic environment. To provide safe and human-friendly environment for walking...
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...
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...
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 propose hardware efficient implementation of lifting based 2-D DWT and Sobel based edge detector for detail diagnosis in Wireless capsule endoscopy (WCE) in real-time. Architecture is developed based on the properties of the endoscopic images and the CMOS sensors. Proposed edge detection scheme works on the compressed DWT coefficients and offers 83.1 % compression ratio (CR). VLSI...
In this paper, we propose a system to superpose information of web services into living space. The system is controlled by natural actions which are gestures and voice in order to simple control apparatus. The system is assembled by three major modules which the sound recognition, the gesture recognition and a projector. We describe the entire process, the implementation and the evaluation of a prototype...
As one of aimed items at Smart Television (Smart TV) and Internet Protocol Television (IPTV), it has been stressed to share watching and enjoying the programs among audiences by using social networks. There have been several proposals to use various approaches. However, the progress of standardization efforts, especially to define an appropriate reputational Ontology for improving the quality of IPTV...
