About the Project
Ambulatory assessments (AA) comprises the use of field methods to assess the ongoing behaviour, physiology, experience and environmental aspects of people in the natural setting. Ecologically-valid tools are used to understand biopsychosocial processes in a spatiotemporal context. This project will examine the dynamical interplay between physical activity, sedentary behaviour, the natural environment and Subjective Well-Being (SWB) in the elderly. Movement and exertion, and in particular, the difference in the amount of physical activity and sedentary behaviour have consistently been found to be related to SWB and a wide range of health outcomes. We will implement new AA methodologies, incorporating t-SNE analysis, with actigraphy based upon state-of-art wearable devices, to offer novel insights into elderly activity and the relationship to SWB with a particular focus of the impact of environmental factors. The study will also incorporate the development and refinement of a prototype AA method to look at intervention with real-time analysis and real-time feedback of physical inactivity and sedentary behaviour.
Methodology: The use of experience sampling and ecological momentary assessment; repeated-entry diary techniques; monitoring of physiological function in combination with or without physical behaviour; acquisition of ambient environmental parameters; applied psychology; statistics and data modelling, psychophysiology, science communication.
Expected progress beyond the state-of-the-art: The project will implement new ambulatory assessments methodologies, incorporating t-SNE analysis, with actigraphy based upon state-of-art wearable devices. This would include the use of accelerometer, magnetometer and gyroscope intelligent multi-sensor based personalized risk assessment systems to monitor gait and stability as well as a wrist device for activity recognition and environmental monitoring.
