Recent developments in ubiquitous and pervasive technologies have made it easier to capture activities through sensors. The “bag-of-word” topic models have been applied to discover latent topics in corpus of words. In this paper, we propose the Probabilistic Latent Semantic Analysis to discover activity routines. The framework we propose set latent topics as corresponding class labels and use the...
One of the key challenges facing spinal cord injury (SCI) patients in today’s modern society is the ability to interface with the digital world around them. This paper outlines a new method of human-computer interaction using a technique that was previously used in Speech and Language Therapy. The system is centred around the user manipulating their tongue to activate and de-activate switches on a...
In order to analyze human gait patterns, highly accurate data must be collected at high frame rates. The state of the art is to deploy a carpet-like structure instrumented with pressure sensors, which allows for measuring position, orientation and pressure of each foot at each step. Since such gait “walkway carpets” are highly expensive1 and also limited in length, we propose an alternative in the...
The analysis of intake behaviour is a key factor to understand the health condition of a subject, such as elderly or people affected by diet-related disorders. The technology can be exploited for this purpose to promptly identify anomalous situations. To this end, the point cloud, provided by a depth camera placed on the ceiling in top-down view, is used as input to three self-organising algorithms...
The integration of Internet of Things (IoT) into our daily lives has the potential to significantly improve the quality of life and well-being of citizens, especially older adults who want to continue to live independently in their own home. In order to realise the potential of IoT in the real-world, there are four major concerns that should be considered: ensuring sensors are un-intrusive, the resources...
The implementation and diffusion of telecare and telehealth products and services falls behind the expectations of policymakers and developers. While several European and national programmes promote the research and development of innovative solutions, products and services have not yet scaled up. This paper tries to identify and categorize existing barriers. We conducted a literature review between...
The Kinect v2 sensor, developed by Microsoft, enables lowcost 3-D motion analysis without the need of markers or other attachments on the human body. Via free Software Development Kit the spatial location of 25 body joints can be extracted at a frame rate of 30 fps. This study evaluates the accuracy of skeleton joint angles obtained by the Kinect in comparison to the golden standard, the marker based...
Dementia is a syndrome characterised by the decline of mental skills such as memory, reasoning, language or perceptual interpretation. High rate of deaths and high cost for detection, treatments and patient’s care count amongst its consequences. The aim of this project is the creation of low cost and efficient tools to help with Alzheimer detection. In addition, current game technologies have proved...
The aim of the study was to understand how patients with dementia were able to navigate in a domestic environment, and whether the presence of visual cues could assist in route finding. A simulated domestic environment was created in the Pedestrian Accessibility and Movement Environment Laboratory (PAMELA) comprising three different types of corridors and an open room with three doors. Three groups...
A comprehensive AAL solution should support independent living, wherever and whatever a person chooses to be and do. Integrating AAL solutions in natural environments such as a garden offers the possibility to encourage activities and physical fitness in a cognitively stimulating setting. Through an intelligent and adapting user interaction concept as presented here, multiple objectives and prevention...
In this paper, we address the development of an innovative service mobile robot for social interaction and home care. Specifically, we focus on the integration of a set of intelligent services in the robot towards natural human-robot interaction, and targeting the 65+ age group. We describe the navigation, perception, interaction, data collection and interfacing capabilities developed using the Robot...
The objective of this paper is to present a novel taxonomy of ambient assisted living (AAL) systems that can be used to describe the AAL systems from a data quality perspective. AAL is an active multi-disciplinary research field that has contributed with many solutions to meet the specific needs of the elderly people. Most of these developments involve experts from different domains. A common terminology...
A novel approach to Web interaction is presented, aiming towards a greater degree of accessibility for blind or low vision people, hence easing the ways of gathering information for investigative purposes. This group of users is facing many and varied difficulties when trying to use Web sites, especially when dealing with hypermedia contents, which are difficult to grasp by simply using screen reader...
The homeService research project is concerned with developing personalised speech-enabled interfaces, in an AAL setting, for users with severe physical impairments and associated disordered speech. By putting state-of-the-art speech recognition systems into people’s homes, invaluable lessons can be learned from doing long-term trials ‘in-the-wild’. The experiences gained from the first homeService...
Sedentarism has a negative impact on health, life expectancy and quality of life, especially in older adults. The assessment of functional fitness helps evaluating the effects of ageing and sedentarism, and this assessment is typically done through validated battery tests such as the Senior Fitness Test (SFT). In this paper we present a computer-based system for assisting and automating SFT administration...
Mindfulness is a secular and scientific psychological technique based on meditation techniques from Eastern traditions with demonstrated efficacy in many illnesses and in psychiatry, as well as its utility in healthy people, in order to increase their well-being and quality of life. This paper presents the first prototype of a mobile application developed by professionals in Spanish language to help...
