Title:

Motion Pattern Generation and Recognition for Mobility Assessments in Domestic Environments

Authors:

Thomas Frenken, Enno-E. Steen and Melina Brell

Abstract: A novel approach to continuous and unobtrusive detection of motion patterns in domestic environments is presented. Motion patterns refer to motion primitives which can be detected via presence events emitted by ambient sensors. The approach enables adaption of the system to heterogeneous environments by building upon two pieces of information: a 2D/3D floor plan of the environment and a definition of available sensors. Using this input the system is capable of generating all information required for the monitoring. This minimizes effort for adaption of the system to other environments. A path-planning algorithm is used to automatically detect possible motion patterns and their length within the environment. A generated sensor-graph and finite state machines enable effective processing of sensor events on a common set-top-box. An experiment with 15 participants was conducted. The system is especially suitable for unobtrusive long-term trend analysis in self-selected gait velocity and does not require direct interaction with people monitored.

Title:

On the Development of an Automatic ECG Monitoring System for Diabetic Patients

Authors:

Nuno Gonçalves and Luis Coelho

Abstract: Diabetes has become progressively common throughout the world due to changes in the lifestyle and in the eating habits. Among other consequences, this disease seriously affects the circulatory system, whose complications are the leading cause of death in diabetics. In this paper we present a new device, developed specifically for diabetics, which allows estimating blood glucose levels and, simultaneously, automatically detect potentially pathological electrocardiographic patterns. We will present the entire processing sequence system and will give special importance to the modules targeting the electrocardiogram (ECG) and its analysis. A set of reference databases has been used as support for performance evaluation. The system proved to be able to effectively detect changes in the ECG morphology for occurrences of different nature and in various contexts. The use of the ECG signal, whose acquisition is non-invasive, provides comfort to the user and has the advantage of allowing a continuous patient monitoring.

Output Matters! Adaptable Multimodal Output for New Telerehabilitation Services for the Elderly

Authors:

António Teixeira, Carlos Pereira, Miguel Oliveira e Silva and Joaquim Alvarelhão

Abstract: Technologies capable of being used by the older adults, with their specificities, to provide new services in the areas of telehealth and Ambient Assisted Living are needed. In this paper, we describe a new service, and its first prototype implementation, in the area of elderly health support at home. Special care was taken to improve the usability, adaptability to user and context and inclusiveness capabilities of the output. The basis for intelligent adaptation of the multimodal output – called AdaptO – is proposed and first versions of the needed services and agents were created.

Title:

The International Classification of Functioning, Disability of Health as a Conceptual Framework for the Design, Development and Evaluation of AAL Services for Older Adults

Authors:

Alexandra Queirós, Joaquim Alvarelhão, Anabela Silva and António Amaro

Abstract: The paper presents the International Classification of Functioning, Disability of Health (ICF) as a comprehensive model for a holistic approach for the design, development and evaluation of Ambient Assisted Living (AAL) services for older adults. ICF can be used to systemize the information that influence individual's performance and to characterize users, theirs contexts, activities and participation. Furthermore, ICF can be used to structure a semantic characterization of AAL services and as a basis to develop methodological instruments for the services evaluation.

Title:

On the Benefits of Speech and Touch Interaction with Communication Services for Mobility Impaired Users

Authors:

Carlos Galinho Pires and Fernando Miguel Pinto

Abstract: Although technology for communication has evolved tremendously over the past decades, mobility impaired individuals still face many difficulties interacting with communication services, either due to HCI issues or intrinsic design problems with the services. In this paper we present the results of a usability study, conducted with a group of five mobility impaired users, comprising paraplegic and quadriplegic individuals. The study participants carried out a set of tasks with a multimodal (speech, touch, gesture, keyboard and mouse) and multiplatform (mobile, desktop) prototype, offering an integrated access to communication and entertainment services, such as email, agenda, conferencing and social media. The prototype was designed to take into account the requirements captured from these users, with the objective of evaluating if the use of multimodal interfaces for communication and social media services, could improve the interaction with such services. Our study revealed that a multimodal prototype system, offering natural interaction modalities, especially supporting speech and touch, can in fact improve access to the presented services, contributing to a better social inclusion of mobility impaired individuals.

Title:

Reliable and Optimal Location System for Monitoring Geolocation Objects

Authors:

Hamid Mcheick and Abdelali Goundafi

Abstract: Location systems for remote objects (vehicle, person, commodity, etc.) are increasingly used today by several enterprises. These systems use positioning devices such as GPS and communication devices to send remote location data and monitor these objects. The constraint of GPS is that it does not provide a precise position at any time. The second constraint is to sending remote location data. Often, the communication devices used for this purpose are GSM modules that send data on the GSM network. The use of GSM network is expensive to send data periodically. To overcome these drawbacks, monitoring prototype is proposed to create a reliable and optimal location system using radio and GPS technologies.

aal@home: A New Home Care Wireless Biosignal Monitoring Tool for Ambient Assisted Living

Authors:

Joana Sousa and Susana Palma

Abstract: In this article we describe a new wireless biosignal system which monitors in a long-term basis, the users at their homes. The system consists of wearable sensors that measure heart rate, blood oxygen saturation and physical activity levels, sending data to a mobile phone and from this to a remote monitoring station located in a clinical facility. Whenever an abnormal situation occurs, an alarm is triggered and caregivers can provide assistance. The system has been deployed at a major Portuguese public hospital and 30 patients under long-term oxygen therapy have been continuously monitored remotely. The results report that the patients feel comfortable and safe when they are continuously remote monitored and for caregivers the system allows them to optimize their time and give better and faster assistance.
