1. An interactive recognition system, comprising:

  • a sensing unit configured to receive light signal;

    a coordinate recognizing unit configured to recognize a coordinate of the light signal received by the sensing unit on the sensing unit and recognize a motion track of the light signal on the sensing unit;

    a determining unit configured to determine a control instruction represented by the motion track; and

    an executing unit configured to execute the control instruction;

    wherein the determining unit comprises a threshold determining subunit, in which a time threshold that the light signal lasts is stored, andthe threshold determining subunit initially determines the light signal as a valid signal when a duration time of the light signal exceeds the time threshold.
