The study was carried out to assess the determinants of household food security among rural households in Sekyere-Afram Plains District of Ghana Data were collected from 100 randomly selected households through the use of structured questionnaires Analytical techniques employed included descriptive statistics to analyze the characteristics of respondent households, and logistic regression model to examine the determinants of food security among the households surveyed Among the variables considered in the model, household size, farm size, off-farm income, credit access, and marital status were found to significantly influence household food security Consistent with a priori expectation, larger households were found to be food insecure compared with households with smaller sizes, ceteris paribus Also, consistent with findings from previous empirical studies, farm size, off-farm income and credit access were found to have significant positive effect on household food security The study, therefore, recommended improved access to credit for rural households and diversification of household economic activities to include off-farm income generating businesses to improve food security at the household level

This paper mainly focuses on the controlling of home appliances remotely and providing security when the user is away from the place. The system is SMS based and uses wireless technology to revolutionize the standards of living. This system provides ideal solution to the problems faced by home owners in daily life. The system is wireless t herefore more adaptable and cost-effective. The HACS system provides security against intrusion as well as automates various home appliances using SMS. The system uses GSM technology thus providing ubiquitous access to the system for security and automated appliance control.

SMS Based Wireless Home Appliance Control System (HACS) for Automating Appliances and Security

Combining ongoing Ambient Intelligence (AmI) technological developments (e.g. pervasive computing, wearable devices, sensor networks etc.) with user-centred design methods greatly increases the acceptance of the intelligent system and makes it more capable of providing a better quality of life in a non-intrusive way. Elderly people could clearly benefit from this concept. Thanks to smart environments, they can experience considerable enhancements, giving them an opportunity to live more independently and for longer in their home rather than in a health-care centre. However, to implement such a system, it is essential to know for whom we are designing. In this paper, we present an intelligent system with a monitoring infrastructure that will help mainly elderly users with impairments to overcome their handicap. The purpose of such a system is to create a safe and intuitive environment that will facilitate the achievement of household tasks in order to preserve independence of elderly residents for a while longer. Pursuing this goal, we propose to use the persona concept to help us build a user model based on the personas' aptitudes. The practice of user modelling emphasizes the importance of user-centred techniques in any AmI system development and highlights the potential impacts of AmI for certain targeted groups - in this case, the elderly and people with disabilities.

User Modelling in Ambient Intelligence for Elderly and Disabled People

The notion of Ambient intelligence (AmI) systems appeared with the main purpose to improve human-environment interaction by means of computerized pervasive environments. Rapidly the research community became aware of the potential of such systems to provide solutions in accordance with each individual, in particular elderly people and people with disabilities, which can undoubtedly benefit from many innovative services related to healthcare, location, security, etc.. In this paper we propose a indoor navigation system for smart buildings,for the elderly and people with disabilities which allows them to reach every place in the building following a personalized secure route. Guiding Under Individual Abilities (GUIA) has been designed taking into account elderly people and people with special needs on way-finding and moving in indoor environments.

Indoor Navigation Multi-agent System for the Elderly and People with Disabilities

Computer systems have shown in the past (Zajicek, 2000) that they can be powerful allies in home-based health care and offer great potential to improve quality of life - but only if they are designed to take into consideration the specific needs of their beneficiaries. Satisfying usability as well as the functional requirements in such a home setting are equally critical. This paper discusses the development of user interfaces, following the “Designfor- all” philosophy, oriented towards a multi-agent system interacting with an intelligent engine. Originally, the system will focus on the control of white goods (large kitchen appliances) but will have scalability properties making it appropriate and extensible for the inclusion of other devices that may be deployed thereafter. The interfaces must be flexible enough to adapt to the targeted public, fit any user’s preferences and/or needs and make the interaction as simple and intuitive as possible. This work is part of the EU FP6 IST e-inclusion ‘EASY LINE+’ project.

Assistive Human-Machine Interfaces for Smart Homes

Smart environments include context-aware computing to enhance system capabilities which affect user interaction positively. A context-aware application should collect contextual information through different ways depending on technology availability and handle this information adequately to execute actions or warnings, present information or modify the environment. Ambient intelligence (AmI) habitually means system complexity and heterogeneity. This paper describes an AmI system case-study, developed for the Easy Line + project, a decentralized intelligence carefully structured in agents grouped by roles in domains to improve system package interaction and integration. The main purposes for this implementation are: avoid complexity and inconsistence between the elements of the system and increase system’s performance. The Easy Line + project is primarily oriented to monitor and control white goods and to assist in emergency situations though it is deployed all over the home environment and can be extended, more easily thanks to the multi-agent approach, to control and monitor other devices or services at home.

Agent-based AmI System Case Study: The Easy Line + Project

Domotics has been favoured by a constant increase of popularity in the last decade. Because of the many home network concepts in this field, it is potentially viable to include several different network technologies in a home automation system; if these technologies are optimally combined then it is presumable to accomplish better results in performance, affordability and stability. For this reason, it is recommended to use each of them for the use of specific services that fit more accurately with their characteristics and capabilities. Nonetheless, besides the diversity of such environments, they all share a common subject: a need for remote control. Actual trends in Domotics are closely oriented to the foremost elements associated with ubiquitous control, which is a significant topic due to the important advantages of having the possibility to manage home services from anywhere at any time. This paper describes a model for a secure, scalable and reliable remote-controlled home automation system; the role of this model is to provide users with a backup gateway to be able to control the services at home (or other buildings) in case of a failure of the main access. The development is focused on a proper handling of the underlying technologies, invisible to the user, to enable the backup gateway agents communicate with both the external agents and the home network agents.
