Classification: CPC A  G | IPC A  G

Claim 8:
9. The method according to claim 1, wherein the action events comprise an i-th action event and an (i+1)-th action event, the speed vectors comprise an i-th speed vector and an (i+1)-th speed vector, 1≤i≤N−1, where N is a number of the action events, and the step of estimating the acceleration vectors corresponding to the action data based on the speed vectors and the time stamp of each of the action events comprises:
subtracting the time stamp of the i-th action event from the time stamp of the (i+1)-th action event to generate an i-th time difference value among a plurality of time difference values;
subtracting the i-th speed vector from the (i+1)-th speed vector to generate an i-th speed difference value among a plurality of speed difference values; and
dividing the i-th speed difference value by the i-th time difference value to generate an (i+1)-th acceleration vector among the acceleration vectors.
