MOBILE SPEED AND POSITION SENSOR FOR HOME HEALTH MONITORING BASED ON ACCELEROMETER SIGNALS

Tamás Dabóczi, Arnold Kalvach

Abstract

This paper presents a study how accelerometer sensors can be used to estimate speed and position by integrating the sensor signals once and twice, respectively. Unfortunately, integration emphasises bias and noise of the sensor. We developed a heuristic nonlinear filter which efficiently suppresses unwanted effects, assuming human movement. Our aim is to provide a mobile sensor to detect the movement of elderly people suffering from dementia, for home health monitoring purposes. Utilising this sensor together with others allows us to detect unusual behaviour of the patient. The two accelerometer signals together with the suggested heuristic nonlinear filtering allows us to reliable measure the speed, and reconstruct the shape of the movement trajectory of the patient.
