    Implicit interaction : a prerequisite for practical AmI
    Intelligent User Interfaces represent one of the three distinguishing characteristics of AmI environments. Such interfaces are envisaged as mediating between the services available in an arbitrary physical environment and its inhabitants. To be effective, such interfaces must operate in both proactive and passive contexts, implicitly and explicitly anticipating and responding to user requests. In either case, an awareness of the prevailing situation is essential – a process that demands a judicious combination of data and decision fusion, as well as collaborative and centralized decision making. Given the constraints of AmI environments realizing a distributed lightweight computational infrastructure augmented with a need to address user needs in a timely manner poses significant challenges. In this paper, various issues essential to enabling seamless, intuitive and instinctive interaction in AmI environments are explored.

    Exercise in the smart workplace
    Employees that engage in even moderate amounts of exercise during their working day suffer less from stress and are more tolerant in the various irritations that accompany normal working life. Though it cannot be said with certainty that such workers are more productive, tentative evidence suggest that this may well be the case. A useful service of a smart office or work environment is to contribute to the health and well-being of those that inhabit such spaces. One practical approach to this is to monitor the exercise that employees engage in during the day, and using this as a basis, motivate them to engage in further physical activity. In this paper, issues relating to monitoring employee physical activity are explored.

    Realizing the ambient intelligence vision through the deployment of mobile, intentional agents
    Ambient computing as an ideal demands levels of functional attainment that have thus far not been realised. Ambient applications require that the computing application be subsumed into the everyday context in an unobtrusive manner with interaction modalities that are natural, simple and appropriate to both the individual user and their associated context. Within this paper, we consider the use of mobile intentional agents as potential key enablers in the delivery of ambient intelligent services. In particular, we compare and contrast two agent-based ambient intelligence case studies

    Towards Holistic Activity Modeling and Behavioral Analyses
    As the age profile of many societies continues to increase, supporting health, both mental and physical, is of increasing importance if independent living is to be maintained. Sensing and, ultimately, recognizing activities of daily living has been perceived as a prerequisite for detecting tasks that people avoid or find increasingly difficult to perform, as well as being indicators of certain illnesses. To date, extensive research efforts have been made on activity monitoring, recognition and assistance in indoor scenarios, frequently through smart home initiatives. However, the scenarios outside of the home have not received a similar degree of attention from the research community. This paper advocates a need for platforms that enable activity recognition in a range of environments, thus enabling the construction of more complex yet realistic activity models and behavior patterns. The design of a prototype supporting an integrated approach to sensor data capture and activity model construction is proposed. The application domain is that of dementia.

    Sense and sensibility : collaborative & interdisciplinary problem design in PBL initiatives
    This paper was conceived in response to an identified need for new PBL practitioners to be able to access a range of sample problems that would help them develop PBL within their own disciplines, particularly when outside of the life sciences. Likewise, a need for new approaches to problem design was also identified. Taking cognisance that problems should be grounded in the ‘real world’, we need to reconceptualise problem design. It is proposed that conceptualising problems as triggers that stimulate knowledge development by harnessing sensory experiences is a way forward. This paper will be of particular interest to new PBL practitioners, teachers in the various disciplines considering PBL and educational developers teaching PBL.

    Pervasive computing technologies for healthcare
    The conference series on Pervasive Computing Technologies for Healthcare is one of the leading fora for research dissemination in this space. In May 2011, the most recent event took place in Ireland. A brief overview of the conference is now presented.

    Ambience & collaboration embedded agents in a human-centered world
    Supporting people in the pursuit of their everyday activities is a laudable objective and one which researchers in various disciplines including computing, actively seek to accomplish. The dynamic nature of the end-user community, the environments in which they operate, and the multiplicity of tasks in which they engage in, all seem to conspire against the desired objective of providing services to the end-user community in a transparent, intuitive and context -aware fashion. Indeed, this inherent complexity raises fundamental problems for software engineers as they frequently lack the tools to effectively model the various scenarios that dynamic user behaviour give rise to. This difficulty is not limited to exotic applications or services; rather, it is characteristic of situations where a number of factors must be identified, interpreted, and reconciled such that an accurate model of the prevailing situation at a given moment in time can be constructed. Only in this way, can services be delivered that take into account the prevailing human, social, environmental and technological conditions. Constructing such services calls for a software solution that exhibits, amongst others, diffusion, autonomy, cooperation and intelligence. In this paper, the potential of embedded agents for realising such solutions is explored.

    Implicit interaction : a modality for ambient exercise monitoring
    Ambient Exercise refers to the implicit exercise that people undertake in the course of their everyday duties - a simple example being climbing stairs. Increasing awareness of the potential health benefits of such activities may well contribute to an increase in a person’s well-being. Initially, it is necessary to monitor and quantify such exercise so that personalized fitness plans may be constructed. In this paper, the implicit interaction modality is harnessed to enable the capturing of ambient exercise activity thereby facilitating its subsequent quantification and interpretation. The novelty of the solution proposed lies in its ubiquity and transparency.

    Diversity & interoperability : wireless technologies in ambient assisted living
    Ambient Assisted Living (AAL) demands the seamless integration of a range of technologies such that the particular needs of the elderly may be met. Given the heterogeneity of the elderly population, in their needs and circumstances amongst others, this is a significant challenge. In essence, it demands that a disparate suite of technologies be deployed, integrated, managed and interacted with in a seamless and intuitive fashion. In this paper, how this heterogeneity may be managed is discussed. In particular, the use of ontologies and middleware are proposed as potential solutions to this heterogeneity problem.

    Orange alerts : lessons from an outdoor case study.
    Ambient Assisted Living (AAL) is of particular relevance to those who may suffer from Alzheimer’s Disease or dementia, and, of course, their carers. The slow but progressive nature of the disease, together with its neurological nature, ultimately compromises the behavior and function of people who may be essentially healthy from a physical perspective. An illustration of this is the wandering behavior frequently found in people with dementia. In this paper, a novel AAL solution for caregivers, particularly tailored for Alzheimer’s patients who are in the early stage of the disease and exhibit unpredictable wandering behavior, is briefly described. Salient aspects of a user evaluation are presented, and some issues relevant to the practical design of AAL systems in dementia cases are identified.
