Abstract:
1. A trajectory information processing device comprising: an input receiving unit which receives input of coordinate information of points included in a continued trajectory by a user in the order in which the trajectory is drawn; a coordinate storage unit which, upon receipt of input of said coordinate information, stores the input coordinate information which was received in the order the input was received; a closed curve storage unit which stores closed curve information; a closed curve acquisition unit which repeatedly performs the following: a vortex information outputting unit which, when closed curve information is newly stored in said closed curve storage unit, calculates the time interval between the time at which the closed curve specified in the newly stored closed curve information is acquired and the time at which the closed curve specified in the closed curve information stored immediately before said newly stored closed curve information is acquired, and outputs a numeric value associated in advance with the calculated time interval as parameter information specified by the user.
