Classification: CPC A  G | IPC A  G

Claim 7:
8. The method according to claim 1, wherein the action events comprise an i-th action event and an (i+1)-th action event, the absolute coordinates comprise an i-th absolute coordinate and an (i+1)-th absolute coordinate, 1≤i≤N−1, where N is a number of the action events, and the step of estimating the speed vectors corresponding to the action data based on the absolute coordinates 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 absolute coordinate from the (i+1)-th absolute coordinate to generate an i-th coordinate difference value among a plurality of coordinate difference values; and
dividing the i-th coordinate difference value by the i-th time difference value to generate an (i+1)-th speed vector among the speed vectors.
