Digital Wellbeing, Living Laboratory Healthy Computing Workshop 2011 Christian Chislett
Living Laboratory– 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)
Activity Recognition with an accelerometer • 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
Results • 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) Falling Sitting
Current work • 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
