An ever-increasing number of people are affected by lifestyle-related health risks, such as overweight, physical inactivity and stress. An ongoing Nuadu trial studies the user acceptance and effectiveness of technologies in supporting the wellness management of working-age citizens. The technologies consist of different Web, mobile and wearable solutions. In this paper, we present the user experience results of three mobile wellness applications: the Wellness Diary, Mobile Coach and SelfRelax. We studied their usefulness, perceived usability, usage habits and motivational factors gathered during the first phase of the trial. The data were collected with user experience questionnaires and interviews, as well as actual usage logs from mobile applications. The findings indicate that the usage habits change during the usage period of more than two months towards more practical ways of use. The results also point out several aspects to be considered when developing future wellness applications for long-term use. These are, e.g. adaptability, versatility, guidance and usability.

We present a design framework for a sensor-based stroke rehabilitation system for use at home developed through the analysis of data collected from a series of workshops. Participants had a variety of backgrounds and included people living with stroke and health professionals who work with them. Our focus in these workshops was to learn more about the social context around stroke care, to share early project ideas and develop a design framework for developing systems. In this paper we present a detailed analysis of participant responses and use this analysis to draw specific conclusions about the components and configuration that we believe should be in future systems.

In this paper we describe a wireless wearable system to monitor gait, based on a customized pair of commercial insoles able to collect ground reaction forces by use of 24 embedded cells for each foot. Each insole was combined with a small form factor, low-power Inertial Measurement Unit (IMU) and enabled to communicate via Bluetooth with a base station. We present here the characterization of the system both in terms of performance and in terms of functionality. The system was tested on a subject to demonstrate the usability and the features extraction during gait; this data allow to recognize walking phase in terms of swing and stance phase, step and stride duration, double support and single support duration, both using the pressure sensors and the IMU.

Pervasive healthcare technology is one of the methods for meeting the challenges of an aging population in many western world countries, as well as an expected major shortage of healthcare personnel. The OpenCare Project is an open source infrastructure framework, designed to be used by researchers and corporate developers for developing experimental assistive living prototypes. The Personal Communication Device is an extension of this infrastructure allowing the user to leave his home while continuing the surveillance of his vital signs through sensors, access to medication reminders and other messages, as well as allowing for easy communication and emergency location services. This paper reports on the current work in progress.

We conducted five focus groups with seniors and middle-aged participants who live independently in their own homes to assess the potential value of a home-centered medication reminder system concept. The medication reminder system was conceptualized as a system that uses a television and set-top box, mobile phones and other in-home accessories as a means to set and deliver medication reminders. We found that the main value perceived by participants in the medication reminder system was its ability to provide multiple channels for them to be reminded of medications. The mobile phone, due to its advantages in portability and privacy, was considered to be the most useful device on which to receive reminders. Most participants saw value in receiving secondary reminders on other devices in their home such as the TV, PC, and other in-home accessories. Design implications along with other findings about the challenges faced by participants in managing their medications are discussed.

Each year millions of people in the world survive a stroke. Movement impairments after stroke are typically treated with intensive, hands-on physical and occupational therapy for several weeks after the initial injury. However, due to economic pressures, stroke patients are receiving less therapy and going home sooner, so the potential benefit of the therapy is not completely realized. Thus, it is important to develop rehabilitation technology that allows individuals who had suffered a stroke to practice intensive movement training without the expense of an always-present therapist. We have developed a low-cost, computer vision system that allows individuals with stroke to practice arm movement exercises at home or at the clinic, with periodic interactions with a therapist. The system integrates a virtual environment for facilitating repetitive movement training, with computer vision algorithms that track the hand of a patient and obtain its 3-D coordinates, using an inexpensive camera and a conventional personal computer. The system, called “Gesture Therapy”, is being evaluated in a controlled clinical trial at a hospital in Mexico City. In this paper we describe the system and discuss the results of a first clinical evaluation.

In this paper we introduce the idea of realizing pervasive health care applications by tailoring the underlying hardware and software to the needs of this specific application. We illustrate the feasibility of our idea by discussing a generalized approach for combining different hardware components as well as a generalized approach for adapting specific software components.

Semantic annotation has been used to combine varied information sources - gathered as unobtrusively as possible - and produce enhanced tools for working with digital resources. In this paper we describe trials carried out using a location tracking system and Semantic Web annotation technologies to analyse activities in a simulated ward environment. The motivation for semantic annotation of the space will be outlined along with the practicalities of the location based tracking system. The integration of location, annotations and video information will be discussed together with the technologies and approaches applicability to use in a real ward environment.

The integration of RFID sensors into everyday products has become a widespread solution for increasing efficiency in supply chain management. This has also led to a way of being able to monitor everyday activities in the home based on when and how these products are used, which is less intrusive than other monitoring approaches such as visual based systems. Monitoring activities in a home environment can be seen as a good way of analyzing behavior and tracking functional decline among elderly people. This paper describes a hierarchal approach for activity recognition using object usage data generated by everyday products used around the home. The motivation of this work is to allow people with early Alzheimer's disease to have additional years of independent living before the disease reaches a stage where the person is fully dependable on someone else.

A robust method of fall and motionless detection is presented. The approach is able to detect falls and motionless periods (standing, sitting, and lying) using only one belt-worn kinematic sensor. The fall detection algorithm analyses the phase changes of vertical acceleration in relation to gravity and impact force using kinematic variables. A phase angle value was used as a threshold to distinguish between falls and normal motion activity. There are two advantages with this approach in comparison with existing approaches: (1) it is computationally efficient and theoretic (2) it is based on a single threshold value which was determined from a kinematic analysis for the falling processes. To evaluate the system, ten subjects were studied each of which performed different types of falls and motionless activities during a period of monitoring activity. These included: normal walking, standing, sitting, lying, a front bend of 90 degrees, tilt over 70 degrees and four kinds of falls (forward, backward, tilt left and right). The results show that 100% of heavy falling, 97% of all falls and 100% of motionless activity were correctly detected in a laboratory environment and the beginning and ends of these events were determined.
