An Electrooculogram-Based Binary Saccade Sequence Classification (Bssc) Technique For Augmentative Communication And Control, Johnalan Keegan, Ted Burke, James Condron
An Electrooculogram-Based Binary Saccade Sequence Classification (Bssc) Technique For Augmentative Communication And Control, Johnalan Keegan, Ted Burke, James Condron

In the field of assistive technology, the electroocu-logram (EOG) can be used as a channel of communication and the basis of a man-machine interface. For many people with severe motor disabilities, simple actions such as changing the TV channel require assistance. This paper describes a method of detecting saccadic eye movements and the use of a saccade sequence classification algorithm to facilitate communication and control. Saccades are fast eye movements that occurs when a person's gaze jumps from one fixation point to another. The classification is based on pre-defined sequences of saccades, guided by a static visual template (e.g. a …
An Investigation Of The Use Of A High Resolution Adc As A Digital Biopotential Amplifier, Damon Berry, Frank Duignan, Richard Hayes
An Investigation Of The Use Of A High Resolution Adc As A Digital Biopotential Amplifier, Damon Berry, Frank Duignan, Richard Hayes
Conference Papers
Sigma delta analogue to digital converters have been used in many signal processing applications including some commercially available systems for sampling of bio-signals Bio-potential amplifiers have traditionally utilised specialised highquality analogue components to amplify bio-signals.
The central aim of this work is to investigate the benefits of using high-resolution sigma delta conversion as a digital amplification stage in the signal path of a bio-potential amplifier. A number of system arrangements specific to bio-potential measurement are presented and discussed. These arrangements are designed to use the high resolution capacity of the sigma delta converter in different ways, providing different benefits. To …
Identity Management To Support Access Control In E-Health Systems, Xu Chen, Damon Berry, William Grimson
Identity Management To Support Access Control In E-Health Systems, Xu Chen, Damon Berry, William Grimson
Conference Papers
The related and often challenging topics of identity management and access control form an essential foundation for e-health infrastructure. Several approaches and supporting specifications for electronic healthcare record system (EHR-S) communication have been proposed by research projects and standards development organizations in recent years. For instance, part four of the CEN TC251 EN13606 EHRcom standard and the HL7 Role Based Access Control Draft Standard for Trial Use have helped to specify the nature of access control behaviour in relation to EHR communication within and between healthcare organisations. Access control services are a core component not only of the integrated care …
A Mobile Ecg Monitoring System With Context Collection, Jin Peng Li, Damon Berry, Richard Hayes
A Mobile Ecg Monitoring System With Context Collection, Jin Peng Li, Damon Berry, Richard Hayes
Conference Papers
Preventative health management represents a shift from the traditional approach of reactive treatment-based healthcare towards a proactive wellness-management approach where patients are encouraged to stay healthy with expert support when they need it, at any location and any time. This work represents a step along the road towards proactive, preventative healthcare for cardiac patients. It seeks to develop a smart mobile ECG monitoring system that requests and records context information about what is happening around the subject when an arrhythmia event occurs. Context information about the subject’s activities of daily living will, it is hoped, provide an enriched data set …
Archetype Alignment: A Two-Level Driven Semantic Matching Approach To Interoperability In The Clinical Domain, Damon Berry, Jesus Bisbal
Archetype Alignment: A Two-Level Driven Semantic Matching Approach To Interoperability In The Clinical Domain, Damon Berry, Jesus Bisbal
Conference Papers
Semantic interoperability between electronic health record systems and other information systems in the health domain implies agreement about the structure and the meaning of the information that is communicated. There are still a number of similar but different EHR system approaches. Some of the newer approaches adopt the two-layer model approach where a generic reference model is constrained by archetypes into valid clinical concepts which can be exchanged. The meaning of the concepts that are represented by an archetype can be conveyed by embedding codes from a commonly recognised terminology at appropriate points in the archetype. However, as the number …
