Local governments in Japan recently provide security information services for residents, which deliver regional incident information using Email or Web. However, since the conventional services usually provide “one-for-all” information. users tend to miss important incidents within the flood of information. In this paper, we propose a new security information service, called PRISM (Personalized Real-time...
Pervasive sensing technologies are promising for increasing one-person households (OPH), where the sensors monitor and assist the resident to maintain healthy life rhythm. Towards the practical use, the recognition of activities of daily living (ADL) is an important step. Many studies of the ADL recognition have been conducted so far, for real-life and human-centric applications such as eldercare...
Supporting deaf and hard of hearing (D/HH) people to understand natural conversation is one of the important activities of social welfare. In our previous paper, we have proposed a multi-modal speech visualization application, which is MIETA in this paper. While the paper proposed the concept of multi-modal speech visualization and its architecture, there is no evaluation about how actually useful...
A number of reminder systems have been developed to help elderly people with dementia. However, the existing reminder systems lack the awareness of human context, the sympathetic human-machine interaction, and the flexibility of personal adaptation. To cope with the limitations, we are currently studying a new reminder service for people with dementia. Specifically, we exploit a BLE-based indoor positioning...
To fix various dependencies of application development using pass-by detection by a mobile device, we propose Pass-by Framework that handles data with standardization. In this study, we evaluate effects of performance of pass-by detection by differences in methods of implementation the sonar of Pass-by Framework. Therefore, we develop pass-by application using Bluetooth Low Energy as a first effort...
In recently years, many care robots have received a lot of attention to help elderly people. However existing care robots have difficult to adopt personalization. For instance, some programmers have to customize robot program to meet needs of each elderly. Even if a care robot which has a feature of machine learning, it takes a long time to learn a preference for each elderly. In this paper, our goal...
To realize indoor environmental sensing, which is a key technology of providing smart services in smart city, with low cost, our research group has proposed a small IoT device named sensor box. In the previous sensor box, however, it is difficult to deploy for the smart city with some problems. In this paper, we propose an indoor environment sensing service using autonomous sensor box to adapt the...
Developing applications with pass-by communication is usually complex and expensive, since the applications heavily depend on the hardware to detect rendezvous (i.e., proximity) of mobile entities. In order to reduce the complexity and cost of the application development, we propose a device-independent formalization of the pass-by rendezvous of mobile entities in this paper. Specifically, we first...
Supporting deaf and hard of hearing (D/HH) people to understand natural conversation is one of the important activities of social welfare. However, currently the communication support for D/HH people is not enough in Japan. Although existing communication methods, such as sign language and lipreading, are effective in one-to-one conversation, they have several disadvantages in one-to-many conversation...
Home Network System (HNS) is a system which provides value-added services by orchestrating household appliances and sensors. In previous work, we have proposed Cloud HNS, which is a new type of HNS based on the concept of Cloud. In this research, we propose IRaaS (Infrared as a Service) that realizes networking control of household appliances controlled by infrared signal, as a Cloud HNS’s appliance...
To achieve efficient presence sensing within home network system (HNS), an inexpensive and elastic system that can be shared by various HNS applications is required. This paper presents Presence Sensor Service Framework, which can uniformly manage presence information in various places using various types of sensors. The framework consists of Presence Sensor Device (PSD), Presence Sensor Terminal...
Code-on-demand is an architectural style that a client dynamically downloads a raw script file and executes it on the client-side. This style causes a problem of network traffic because a raw script is not always compiled or minified in advance. Formatting rules, such as indents, line breaks and comments for ensuring human readability, are not necessary to the execution. In order to save wasteful...
Managing a home server within individual house is a major obstacle to practical use of home network system (HNS). Delegating the home server to a cloud is a promising approach. However, the conventional multitenant SaaS-based solution has the following risks among different households: security/privacy violation, failure propagation and insufficient resource demand. In this paper, we propose a novel...
The goal of this paper is to find an answer that how remote monitoring sensor should be accurate. To achieve the goal, we propose three methods, generalization by three-actor model, design the algorithm of the three-actor and development of RMS simulator. With the three-actor model, we can generalize RMS by interactions among three actors. As the second step, we design the algorithms that how to work...
We have been studying Cloud HNS, which is a new type of home network system using the cloud. In this paper, we consider value-added services that can be provided by introducing a smart TV as an appliance of Cloud HNS. First, we discuss requirements, role and benefits of a smart TV in the integration with Cloud HNS. Then, we propose concrete scenarios of value-added services achieved by the integration.
We have been studying log contexts using large-scale house log collected in home network system (HNS). A log context is defined with both the current and past situations of a house, where the current situation is characterized by the current status of an appliance (or a sensor), while the past situations are derived from the house log. In this paper, we propose context-aware services for smart TVs...
Research and development of home network system (called HNS.) is recently a hot topic in the area of ubiquitous computing applications. Orchestrating house-hold appliances (e.g., TVs, DVDs, speakers, air-conditioners, lights, curtains, windows, et al.) via the network, the HNS provides value-added services for home users. In our previous research, we have proposed and developed HNS-VAUI that is the...
Motion correction using particle filter is proposed and the comparison of three algorithms for human head motion correction of functional magnetic resonance imaging are performed. The traditional algorithm of gradient descent method, random sampling, and proposed particle filtering are used to correct the motion of real scanned human brain images. The result shows the particle filter achieves reasonably...
With the spread of Machine-to-Machine (M2M) systems and cloud services, various kinds of data are available through Web services. A context-aware service recognizes a real-world context from such data and behaves autonomously based on the context. However, it has been challenging to manage contexts and services defined on the heterogeneous and distributed Web services. In this paper, we propose a...
A home network system (HNS) provides value-added services for home users by networking house-hold appliances and sensors. In the conventional architecture, the HNS appliances and services are tightly coupled. It is therefore difficult for users to freely choose their favorite appliances and services. In this paper, we propose a new HNS architecture that accommodates multi-vendor services by extensively...
