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...
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...
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...
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...
We have previously proposed the ReceiptLog service platform, which stores user's purchase histories from daily receipts for value-added consumer services. As a practical application of the ReceiptLog, we design and implement a shopping support service, called "Sma-Sho", in this paper. Sma-Sho is designed to cope with two typical problems in daily shopping: duplicate purchase and forgotten...
