Abstract
The present inventions, in one aspect, are directed to a portable monitoring device comprising (i) a housing having a physical size and shape that is adapted to couple to the user, (ii) a motion sensor, disposed in the housing, to detect motion of the user and, in response thereto, to generate motion data, (iii) an altitude sensor, disposed in the housing, to sample an altitude of the user in response to a sample signal, wherein, in response to sampling the altitude of the user, the altitude sensor generates change in altitude data, and (iv) processing circuitry, disposed in the housing, to: generate the sample signal using the motion data, and calculate a number of stairs or flights of stairs traversed by the user using the motion data and the change in altitude data.
