Ontology-Enabled Activity Learning and Model Evolution in Smart Homes
(Springer, Berlin, Heidelberg, 2010-10-26)
Activity modelling plays a critical role in activity recognition and assistance in smart home based assisted living. Ontology-based activity modelling is able to leverage domain knowledge and heuristics to create Activities ...
Sensor-Based Activity Recognition
Research on sensor-based activity recognition has, recently, made significant progress and is attracting growing attention in a number of disciplines and application domains. However, there is a lack of high-level overview ...
A Conceptual framework for Adaptive User Interfaces for older adults
Nowadays, information and communication technologies (ICT) have become part of our everyday life, enhancing the quality of life and promoting new forms of social interaction. Despite the numerous benefits of ICT, older ...
Extending knowledge-driven activity models through data-driven learning techniques
(Pergamon Press, Inc. Tarrytown, NY, USA, 2015-04-15)
We combine knowledge- and data-driven approaches for activity modeling.We develop a novel clustering algorithm that uses prior domain expert knowledge.A new learning algorithm to model activities from extracted clusters.We ...
A mechanism for nominating video clips to provide assistance for instrumental activities of daily living
Current assistive smart homes have adopted a relatively rigid approach to modeling activities. The use of these activity models have introduced factors which block adoption of smart home technology. To address this, goal ...
WiiPD - An Approach for the Objective Home Assessment of Parkinson's Disease
Activity modelling and discovery plays a critical role in smart home based assisted living. Existing approaches to pattern recognition using data-intensive analysis suffers from various drawbacks. To address these shortcomings, ...
A Hybrid Evaluation Methodology for Human Activity Recognition Systems
Evaluating human activity recognition systems usually implies following expensive and time consuming methodologies, where experiments with humans are run with the consequent ethical and legal issues. We propose a hybrid ...
Discovering social behaviour variances of younger and older users through social interaction analysis
(International Journal of Web Science, 2013)
The popularity of social networking has risen considerably in recent years, increasing opportunities for social interaction. As an approach, it has the potential to reduce the burden of social isolation for older users. ...
International Workshop on Situation, Activity and Goal Awareness (SAGAware 2012)
proceedings of SAGAWare2012 workshop
Combining ontological and temporal formalisms for composite activity modelling and recognition in smart homes
Activity recognition is essential in providing activity assistance for users in smart homes. While significant progress has been made for single-user single-activity recognition, it still remains a challenge to carry out ...
