Patent ID: 8234576

Claim:
An interaction data processing apparatus for processing interaction data of a terminal unit, wherein the interaction data includes first information denoting whether or not the terminal unit has faced a different terminal unit and second information which has acceleration information denoting acceleration of the terminal unit; wherein the interaction data processing apparatus includes a receiving unit for receiving interaction data from the terminal unit, a control unit for processing the received interaction data, and an output unit for outputting the processed interaction data; wherein the receiving unit receives interaction data from the terminal unit; wherein the control unit processes the received interaction data; wherein the output unit outputs the first and second information items included in the processed interaction data so as to be related to each other according to a time: wherein the control unit classifies a movement state of a terminal unit that has sent the second information according to acceleration information included in the second information and adds the information denoting the classified movement state to the second information; wherein the control unit calculates an average value within a predetermined period of acceleration information included in the second information and adds the calculated average value to the second information; wherein the control unit calculates an amount of acceleration change of a terminal unit that has sent the second information according to acceleration information included in the second information and adds the calculated amount of acceleration change to the second information; wherein the terminal unit decides whether or not a radio signal including identifying information for identifying the different terminal unit has been received at a predetermined time interval; wherein the control unit counts the number of times the terminal unit has received the radio signal within a predetermined period longer than the predetermined time interval; and wherein the control unit, when the count exceeds a predetermined threshold, adds information denoting that the terminal unit that has received the radio signal has faced the terminal unit that has sent the radio signal for the predetermined period to the first information.
