In this paper a psychologist discusses the desirable relationship between the elderly and Artificial Objects based on some questions raised by an engineering researcher. Concretely, the paper discusses the differences between Objects, Machines, and Artificial Objects. Through this, it reveals the characteristic of Artificial Objects and presents the following four points that can be potentially problematic...
Services for smart home share a fundamental problem—object recognition, which is challenging because of complex background and appearance variation of object. In this paper we develop a framework of object recognition for smart home integrating SIFT (scale invariant feature transform) and context knowledge of home environment. The context knowledge includes the structure and settings of a smart home,...
In this paper we propose a gentle system for watching over for pervasive care-support services that fulfill users’ actual requirements and without interfering the users’ privacy. In this system, we cope with not only the user’s physical location but also all the situations of pervasive devices and requirements of associated users, in “both” sides of watching and watched sites. Moreover, social relationships...
This paper defines a new, context-driven programming model for pervasive spaces. Existing models are prone to conflict, as it is hard to predict the outcome of interleaved actions from different services, or even to detect that a particular device is receiving conflicting instructions. Nor is there an easy way to identify unsafe contexts and the emergency remedy actions, or for programmers and users...
Tracking the movement of people in indoor environments is useful for a variety of applications including elderly care, study of shopper behavior in shopping centers, security etc. There have been several previous efforts at solving this problem but with limited success. Our approach uses inexpensive pressure sensors, placed in a specific manner, that allows us to identify multiple people. Given this...
This paper presents a novel smart mote-based portable medical system which automatically monitors and handles medication among persons with dementia based on wireless multimodal sensors, actuators and mobile phone or PDA (Personal Digital Assistance) technology. In particular, we present the subtle design, implementation and deployment issues of monitoring the patient’s behavior and providing adaptive...
Those suffering from mild dementia exhibit impairments of memory, thought and reasoning. It has been recognised that deployment of technological solutions to address such impairments may have a major positive impact on the quality of life and can be used to help perform daily life activities hence maintaining a level of independence. In this paper we present an overview of our current investigations...
This paper proposes an approach to collision-free navigation for multiple moving agents in a smart home environment using the visibility map which is one of road maps. The visibility map plans collision-free paths of agents against stationary obstacles. The collision-free paths are represented by Hermite curves taking into consideration smoothness of the path and its first derivative. For collision-free...
We consider two problems related to communication between geographically distributed family members. First, we examine the problem of supporting peripheral awareness, in order to improve both emotional well-being and awareness of family activity. This is based on a field study to determine the role and importance of various peripheral cues in different aspects of everyday activities. The results from...
Nowadays the concept of ”pervasive computing” is fully deployed in smart environments to bring more comfort and to allow an easy access to services for users. Due to this fact it is essential to reconsider some security service delivery in smart environments. The authentication service is tightly related to the user and must imperatively take into account his capacities, his preferences and his environment,...
In public places, information can be accessed by its unauthorized users, while we are sometimes forced to access our unwanted information unexpectedly. We have introduced the concept of Secure Spaces, physical environments where any information is always protected from its unauthorized users, and have proposed a content-based entry control model and an architecture for Secure Spaces which protect...
This paper describes a Ventricular Tachycardia/Fibrillation (VT/VF) detection algorithm that is specifically designed for a 24/7 personal wireless heart monitoring system. This monitoring system uses Bluetooth enabled bio-sensors and smart phones to monitor continuously cardiac patients’ vital signs. Our VT/VF algorithm is optimized for continuous real-time monitoring on smart phones with a high sensitivity...
This work describes a potential solution to the problems caused by the heterogeneous nature of the data which may be collected within smart home environments. Such information may be generated at an intra- or inter-institutional level following laboratory testing or based on in-situ evaluations. We offer a solution to this problem in the form of a system/application/format independent means of storing...
This paper formalizes three kinds of safety to be satisfied by networked appliances and services in the emerging home network system (HNS). The local safety is defined by safety instructions of individual networked appliances. The global safety is specified as required properties of HNS services, which use multiple appliances simultaneously. The environment safety is derived from residential rules...
This paper implements the Multi-Modal Instruction Agent (hereinafter, MMIA) including a synchronization between audio-gesture modalities, and suggests improved fusion and fission rules depending on SNNR (Signal Plus Noise to Noise Ratio) and fuzzy value, based on the embedded KSSL (Korean Standard Sign Language) recognizer using the WPS (Wearable Personal Station) and Voice-XML. Our approach fuses...
It is common for nowadays family with two working parents. Children therefore has more unsupervised time than before. Being alone, they are more likely to avoid hard subjects, like math. They could also improperly spend their time and energy. Internet addiction is one of the examples. This research designates software agent, with a life like interface, as a learning buddy to accompany kids and school...
Ubiquitous computing is changing our daily life with evolving devices. A mirror, which is one of our daily tools, is also showing its role changing to the instrument of information displayer. These evolving devices already have their own traditional roles and interaction methods. Therefore, one of the most important factors for the implementation of these devices is the interaction methods between...
This paper describes a novel approach based on the user interface presentation of unknown services within a pervasive environment dedicated to dependant people. The idea is to map the heterogeneity of the environment objects into abstracted service. At the level of the user interface, this will allow the personalization and the adaptation based on user’s requirements. Service provision has to be effective...
To foster the mobility of people with cognitive impairements, cognitive orthoses on mobile devices can have a major impact on patients and caregivers quality of life. But patient and caregivers must be implied in the process of design such orthoses. In this paper we describe an iterative process relying on a user-centered approach. On the one hand, it enabled to improve the design and usability of...
