Method and system for triggering and controlling human-computer interaction operating instructions

A method for triggering and controlling a human-computer interaction operating instruction, the method comprising the steps of:

• pre-storing a mapping relationship between a display mode of a light source in at least one photograph image frame and a human-computer interaction instruction, wherein the display mode of the light source in the photograph image frame is selected from a group consisting of a predetermined region, a movement trace, a color and a flashing pulse;
• acquiring the photograph image frame generated by a photographing device;
• detecting the light source in the photograph image frame for analyzing the display mode of the detected light source in the photograph image frame, wherein the step of detecting the light source in the photograph image frame for analyzing the display mode further comprises the steps of:
• constructing a grid coordinate system in the photograph image frame for continuously identifying the light source in the photograph image frame, and computing a plurality of grid coordinates of the grid coordinate system of the light source in the photograph image frame for generating the grid coordinates of the movement trace of the light source;
• and
• determining the movement trace of the light source within the photograph image frame by calculating a plurality of grids associated with the grid coordinates along a direction formed by the grids;
• and
• determining the human-computer interaction instruction corresponding to the display mode of the detected light source in the photograph image frame for triggering the human-computer interaction instruction based on the pre-stored mapping relationship.
