COMPARING TWO CONTINUOUS COMPUTER GENERATED LINES GENERATED BY THE MOVEMENTS OF A COMPUTER MOUSE OR A DIGITIZER TABLET

摘要

A process for comparing two computer-generated lines, each of which is represented by a plurality of points in space and a corresponding time at which each point was made, involves computing an area, velocity and angular velocity for each line and, along with the time values, comparing these against its counterpart metric in the other line. These comparisons may be weighted for importance and then summed to produce a single number. Where this resulting number is greater than or equal to a threshold, the two lines may be determined to be similar.
