- This article describes an investigation to determine the optimal placement of accelerometers for the purpose of detecting a range of everyday activities. The paper investigates the effect of combining data from accelerometers placed at various bodily locations on the accuracy of activity detection. Eight healthy males participated within the study. Data were collected from six wireless tri-axial accelerometers placed at the chest, wrist, lower back, hip, thigh and foot. Activities included walking, running on a motorized treadmill, sitting, lying, standing and walking up and down stairs. The Support Vector Machine provided the most accurate detection of activities of all the machine learning algorithms investigated. Although data from all locations provided similar levels of accuracy, the hip was the best single location to record data for activity detection using a Support Vector Machine, providing small but significantly better accuracy than the other investigated locations. Increasing the number of sensing locations from one to two or more statistically increased the accuracy of classification. There was no significant difference in accuracy when using two or more sensors. It was noted, however, that the difference in activity detection using single or multiple accelerometers may be more pronounced when trying to detect finer grain activities. Future work shall therefore investigate the effects of accelerometer placement on a larger range of these activities.

- The demands for smart environments, which can help to facilitate as well as monitor independent living are increasing. With this comes a desire for decision support rules to process data recorded from such environments. However, testing and evaluating rules can be both time-consuming and indeed stressful for the inhabitants. Within this paper we propose a model, referred to as HomeRuleML, for representing decision support rules for smart environments. The motivating factor behind such a proposal is to provide a widely and freely accessible set of rules which can be openly used and exchanged within the research domain and beyond. This model has the potential to decrease the time required for deployment, and inevitability improve the inhabitants' quality of life. In the paper we explain in detail the structure of adopting this approach and also provide an indication of the typical types of software tools required for its use.

Konferensbidrag (refereegranskat)abstract
- Due to the change in global demographics, a significant amount of research is being directed towards developing solutions to monitor and support the ageing as they perform activities of daily living. Research in this area is, however, being limited by the lack of shareable datasets available to support the development and evaluation of data driven activity recognition models. In our current work we have developed a suite of resources in an attempt to establish an openly available data repository where all datasets share a common format for the purposes of data storage. Within this paper the homeML Toolkit and the homeML Repository are presented. Results from a usability study of interactions with the toolkit, conducted by five computer science researchers are presented; the initial findings of which have been encouraging

- The lack of a standard format to store data generated within the smart environments research domain is limiting the opportunity for researchers to share and reuse datasets. The opportunity to exchange datasets is further hampered due to the lack of an online resource to facilitate this. In our current work we have attempted to resolve these issues through the development of homeML, a proposed format to support the storage and exchange of data generated within a smart environment and the homeML suite, an online tool to support data exchange and reuse. A usability and functionality study performed by 8 unbiased members of the research community is presented and discussed. All participants in the study agreed that the homeML format could address the need for a standard format within this domain. Participants also agreed that the homeML suite would be a useful tool to be available to researchers as they perform experiments in the area of smart environments.

- The lack of a standard format for storing data generated within the smart environments research domain is limiting the opportunity for researchers to compare and share datasets. The opportunity to re-use and share datasets is also being limited due to lack of an online resource available to researchers. In our current work we attempt to resolve these issues through the creation of homeML, a proposed format for storing and sharing data and the development of the homeML Suite as a means of supporting the use of homeML. Within this article the latest version of homeML, version 2.2 is presented, where the 'annotationDetails' element is introduced. An extended evaluation of the homeML Suite is also discussed. A usability and functionality study was conducted by a number of experienced researchers working within the domain of smart environments. The methodology of both studies is discussed in detail. Each participant's interactions with homeML and the suite of tools is presented, the findings of which have been positive. All participants agreed that the homeML Suite would be a useful tool to be available within the research domain and they would recommend it to their fellow researchers.

- The potential of smart living environments to provide a form of independent living for the ageing population is becoming more recognised. These environments are comprised of sensors which are used to assess the state of the environment, some form of information management to process the sensor data and finally a suite of actuators which can be used to change the state of the environment. When providing a form of support which may impinge upon the well being of the end user it is essential that a high degree of reliability can be maintained. Within this paper we present an information management framework to process sensor based data within smart environments. Based on this framework we assess the impact of sensor reliability on the classification of activities of daily living. From this assessment we show how it is possible to identify which sensors within a given set of experiments can be considered to be the most critical and as such consider how this information may be used to propose a set of guidelines which may be adopted for managing sensor reliability from a practical point of view.

- The demands of introducing more practical means of managing and monitoring technology within the home environment to support independent living are increasing. Within this paper we present a prototype solution referred to as HomeCI which allows healthcare professionals to establish the conditions within which technology in the home should operate. The HomeCI concept is based on the use of visual notation and has been designed for use by persons with a non technical background. Within the paper we present the design of the first version of the HomeCI visual editor and present the results of a usability study conducted on 4 healthcare professionals.

Konferensbidrag (refereegranskat)abstract
- 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 interinstitutional 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 such data. This approach will inevitably support the exchange of data within the research community and form the basis of the establishment of an openly accessible data repository. Within this abstract we present the outline design of homeML, an XML based schema for representation of information within smart homes and through exemplars demonstrate the potential of such an approach. An example of the typical type of software browser required for the data representation is also presented.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Remote healthcare monitoring is the process of assessing the well-being of a patient when the patient and their healthcare professional are not located together. Advances in technology, specifically medical devices, sensors and high speed fixed and wireless communication networks have made it possible to bring the assessment process to the patient, as opposed to limiting the assessment to the constraints of hospitals and doctors' surgeries. It is also possible for patients to benefit from expert consultants anywhere in the world and receive their advice, without a face-to-face meeting. We discuss these issues in the context of home based medication management and propose a technical solution using emerging technologies. This uses a base station acting as a reservoir of medication and a means to connect the patient to an Internet based care model. The following details of the system are presented; an Internet portal in the form of a web based interface to support the prescribing of medication; an interface for the pharmacist to support the filling of medication containers; a caregiver's interface that provides a means to assess the patient's adherence to their medication regimen.
