1. An apparatus comprising:
a processor, the processor performing operations comprising; computing, during a calibration phase, at least one walking motion metric obtained from a measured local motion of a user under a condition where the user has walked a first real distance, wherein the at least one walking motion metric comprises an estimated walking distance value computed by employing a walking motion algorithm during the condition, wherein the estimated walking distance value represents an estimate of the first real distance acquired by employing the walking motion algorithm; computing, during the calibration phase, at least one running motion metric obtained from a measured local motion of the user under a condition where the user has run a second real distance which may be the same as or different from the first real distance, wherein the at least one running motion metric comprises an estimated running distance value computed by employing a running motion algorithm during the condition, wherein the estimated running distance value represents an estimate of the second real distance acquired by employing the running motion algorithm; computing a calibration value for one of running measurements and walking measurements on the basis of both the estimated running distance value and the estimated walking distance value by using a relationship between the estimated walking distance value and the estimated running distance value; and calibrating, using the calibration value, at least one of running and walking measurements during an exercise phase, thereby decreasing inaccurary of the apparatus in its determination of at least one of the running and walking measurements during the exercise phase without requiring entry of a predetermined distance and use of and existing calibration model during the calibration phase. |
