Active interactive navigation system and active interactive navigation method

An active interactive navigation system includes a display device, a target object image capturing device, a user image capturing device, and a processing device. The target object image capturing device captures a dynamic object image. The user image capturing device obtains a user image. The processing device recognizes and selects a service user from the user image and captures a facial feature of the service user. If the facial feature matches facial feature points, the processing device detects a line of sight of the service user and accordingly recognizes a target object watched by the service user, generates face position three-dimensional coordinates corresponding to the service user, position three-dimensional coordinates corresponding to the target object, and depth and width information, accordingly calculates a cross-point position where the line of sight passes through the display device, and display virtual information of the target object on the cross-point position of the display device.
