Activity monitoring using accelerometers is of growing interest. Acceleration contains information about intensity and frequency of activities. An additional barometer provides information on altitude. This paper presents an evaluation of several features with respect to their suitability for recognizing resting, walking, cycling, going upand downstairs. Two classifiers are proposed: one using ...

As various smart devices are introduced, the application software for analyzing the pattern and the quantity of exercise is addressed as a promising smart-phone application. In this paper, we propose a classification scheme of ambulatory movements with barometer and accelerometer of a smart-phone. According to the experimental results, the difference of barometer datum can provide the character...

Altimeter and sea level pressure data from the Geosat mission are analyzed for evidence of inverted barometer response of sea level to atmospheric pressure forcing. Estimates of the inverted barometer coeecient are given for a variety of geographic regions and time scales using various orbit error removal strategies. There is some sensitivity to the orbit error removal method, but the estimated...
