DETECTION METHOD FOR VOLLEYBALL TECHNIQUE

摘要

The present invention concerns a method of detection for an electronic apparatus comprising a case containing an electronic module powered with electrical energy by a means of storing electrical energy, said electronic module including a calculation unit connected to an acceleration sensor and to a memory unit, said electronic module also being connected to a display means so as to display information linked to some data of said acceleration sensor.The method comprises high-pass filtering acceleration sensor data, low-pass filtering the norm of the high-pass filtered data, then filtering maxima, then low-pass filtering and down-sampling data, classifying data so as to determine what activity occurred, and characterizing the activity by a 1-Nearest Neighbor algorithm using the L1-norm in the down-sampled acceleration space.
