Healthy Computing Workshop 2011 Christian Chislett

 Research Assistant for the Digital Wellbeing project  Living Laboratory – build up a network of sensor technologies and analyse the results  Aim – to improve and develop sensors to be used in assisted living  PhD – (Remote healthcare security)

 Aim – to recognise different scenarios such as; walking, sitting down and falling  Texas chronos watch  A 3-axis accelerometer  Wirelessly transmits data to a computer/laptop  Fast Fourier Transformations

 Can differentiate between walking and falling  Sitting and falling problematic  Needs a different approach such as; axis correlation, neural nets or combination of axes  Paper published - (Pervasive Health Conference, 2011, Dublin) FallingSitting

 A limitation of the described method is the unknown orientation of the watch  Build a gyro-free inertial measurement system  Enable us to correctly identify the Z axis  Possibly track the user and monitor activity/inactivity
