Activities recognition and worker profiling in the intelligent office environment using a fuzzy finite state machine
Analysis of the office workersâ activities of daily working in an intelligent office environment can be used to optimize energy consumption and also office workersâ comfort. To achieve this end, it is essential to recognise office workersâ activities including short breaks, meetings and non-computer activities to allow an optimum control strategy to be implemented. In this paper, fuzzy finite state machines are used to model an office workerâs behaviour. The model will incorporate sensory data collected from the environment as the input and some pre-defined fuzzy states are used to develop the model. Experimental results are presented to illustrate the effectiveness of this approach. The activity models of different individual workers as inferred from the sensory devices can be distinguished. However, further investigation is required to create a more complete model
Integration of multisensor hybrid reasoners to support personal autonomy in the smart home.
The deployment of the Ambient Intelligence (AmI) paradigm requires designing and integrating user-centered smart environments to assist people in their daily life activities. This research paper details an integration and validation of multiple heterogeneous sensors with hybrid reasoners that support decision making in order to monitor personal and environmental data at a smart home in a private way. The results innovate on knowledge-based platforms, distributed sensors, connected objects, accessibility and authentication methods to promote independent living for elderly people. TALISMAN+, the AmI framework deployed, integrates four subsystems in the smart home: (i) a mobile biomedical telemonitoring platform to provide elderly patients with continuous disease management; (ii) an integration middleware that allows context capture from heterogeneous sensors to program environmentÂżs reaction; (iii) a vision system for intelligent monitoring of daily activities in the home; and (iv) an ontologies-based integrated reasoning platform to trigger local actions and manage private information in the smart home. The framework was integrated in two real running environments, the UPM Accessible Digital Home and MetalTIC house, and successfully validated by five experts in home care, elderly people and personal autonomy
Progress in ambient assisted systems for independent living by the elderly
One of the challenges of the ageing population in many countries is the efficient delivery of health and care services, which is further complicated by the increase in neurological conditions among the elderly due to rising life expectancy. Personal care of the elderly is of concern to their relatives, in case they are alone in their homes and unforeseen circumstances occur, affecting their wellbeing. The alternative; i.e. care in nursing homes or hospitals is costly and increases further if specialized care is mobilized to patientsâ place of residence. Enabling technologies for independent living by the elderly such as the ambient assisted living systems (AALS) are seen as essential to enhancing care in a cost-effective manner. In light of significant advances in telecommunication, computing and sensor miniaturization, as well as the ubiquity of mobile and connected devices embodying the concept of the Internet of Things (IoT), end-to-end solutions for ambient assisted living have become a reality. The premise of such applications is the continuous and most often real-time monitoring of the environment and occupant behavior using an event-driven intelligent system, thereby providing a facility for monitoring and assessment, and triggering assistance as and when needed. As a growing area of research, it is essential to investigate the approaches for developing AALS in literature to identify current practices and directions for future research. This paper is, therefore, aimed at a comprehensive and critical review of the frameworks and sensor systems used in various ambient assisted living systems, as well as their objectives and relationships with care and clinical systems. Findings from our work suggest that most frameworks focused on activity monitoring for assessing immediate risks while the opportunities for integrating environmental factors for analytics and decision-making, in particular for the long-term care were often overlooked. The potential for wearable devices and sensors, as well as distributed storage and access (e.g. cloud) are yet to be fully appreciated. There is a distinct lack of strong supporting clinical evidence from the implemented technologies. Socio-cultural aspects such as divergence among groups, acceptability and usability of AALS were also overlooked. Future systems need to look into the issues of privacy and cyber security

Behavioural pattern identification and prediction in intelligent environments
In this paper, the application of soft computing techniques in prediction of an occupant's behaviour in an inhabited intelligent environment is addressed. In this research, daily activities of elderly people who live in their own homes suffering from dementia are studied. Occupancy sensors are used to extract the movement patterns of the occupant. The occupancy data is then converted into temporal sequences of activities which are eventually used to predict the occupant behaviour. To build the prediction model, different dynamic recurrent neural networks are investigated. Recurrent neural networks have shown a great ability in finding the temporal relationships of input patterns. The experimental results show that non-linear autoregressive network with exogenous inputs model correctly extracts the long term prediction patterns of the occupant and outperformed the Elman network. The results presented here are validated using data generated from a simulator and real environments
Service-Oriented Device Integration for Ubiquitous Ambient Assisted Living Environments
As a result of the increment of population in countries of Europe, a
lot of efforts from European Authorities are coming from. In our research we
want to bring forward a suite of developments related to build a ubiquitous
AAL (Ambient Assisted Living) environment. We consider that recent approaches
are based on ad-hoc technologies so its application is in this context
isolated just in one domain of application. Our approach addresses to a reliable
services platform for heterogeneous devices integration. On this basis we want
to consider as well, the underlying benefits that a Service-oriented platform is
giving to us in our Ambient Assisted Living Applications.Ministerio de EducaciĂłn y Ciencia TSI2006-13390-C02-02Junta de AndalucĂa TIC-2141Ministerio de Industria, Turismo y Comercio TSI-020400-2008-11
Enhancement of a body area network to support smart health monitoring at the digital home
The deployment of home-based smart health services requires effective and reliable systems for personal and environmental data management. ooperation between Home Area Networks (HAN) and Body Area Networks (BAN) can provide smart systems with ad hoc reasoning information to support health care. This paper details the implementation of an architecture that integrates BAN, HAN and intelligent agents to manage physiological and environmental data to proactively detect risk situations at the digital home. The system monitors dynamic situations and timely adjusts its behavior to detect user risks concerning to health. Thus, this work provides a reasoning framework to infer appropriate solutions in cases of health risk episodes. Proposed smart health monitoring approach integrates complex reasoning according to home environment, user profile and physiological parameters defined by a scalable ontology. As a result, health care demands can be detected to activate adequate internal mechanisms and report public health services for requested actions
Distributed Online Machine Learning for Mobile Care Systems
Appendix D: Wavecomm Tech Docs removed for copyright reasonsTelecare and especially Mobile Care Systems are getting more and more
popular. They have two major benefits: first, they drastically improve
the living standards and even health outcomes for patients. In addition,
they allow significant cost savings for adult care by reducing the needs
for medical staff. A common drawback of current Mobile Care Systems
is that they are rather stationary in most cases and firmly installed in
patientsâ houses or flats, which makes them stay very near to or even in
their homes. There is also an upcoming second category of Mobile Care
Systems which are portable without restricting the moving space of the
patients, but with the major drawback that they have either very limited
computational abilities and only a rather low classification quality or,
which is most frequently, they only have a very short runtime on battery
and therefore indirectly restrict the freedom of moving of the patients
once again. These drawbacks are inherently caused by the restricted
computational resources and mainly the limitations of battery based power
supply of mobile computer systems.
This research investigates the application of novel Artificial Intelligence
(AI) and Machine Learning (ML) techniques to improve the operation of
2
Mobile Care Systems. As a result, based on the Evolving Connectionist
Systems (ECoS) paradigm, an innovative approach for a highly efficient
and self-optimising distributed online machine learning algorithm called
MECoS - Moving ECoS - is presented. It balances the conflicting needs
of providing a highly responsive complex and distributed online learning
classification algorithm by requiring only limited resources in the form of
computational power and energy. This approach overcomes the drawbacks
of current mobile systems and combines them with the advantages of
powerful stationary approaches. The research concludes that the practical
application of the presented MECoS algorithm offers substantial improvements
to the problems as highlighted within this thesis
Implementation and Application of Artificial Intelligence in Selected Public Services
Data-intensive technologies, such as artificial intelligence, imply huge opportunities for transforming the delivery of healthcare and social services, improving peopleâs quality of life and working in the health and welfare system. The aim of this paper is to present examples of the implementation of artificial intelligence techniques in healthcare and social services and to sketch the trends and challenges in the adoption of artificial intelligence techniques, with an emphasis on the public sector and selected public services. Analysis is based on a realistic assessment of current artificial intelligence technologies and their anticipated development. Besides the benefits and potential opportunities for healthcare and social services, there are also challenges for governments. Understanding the huge potential of artificial intelligence as well as its limitations will be a key step forward, but it is essential to avoid the trap of an overestimation of artificial intelligence potential
Cognitive assisted living ambient system: a survey
The demographic change towards an aging population is creating a significant impact and introducing drastic challenges to our society. We therefore need to find ways to assist older people to stay independently and prevent social isolation of these population. Information and Communication Technologies (ICT) provide various solutions to help older adults to improve their quality of life, stay healthier, and live independently for a time. Ambient Assisted Living (AAL) is a field to investigate innovative technologies to provide assistance as well as healthcare and rehabilitation to impaired seniors. The paper provides a review of research background and technologies of AAL
