1. A method of presenting interactive 3D video content to an audience, the method comprising:

  • providing an audience area for accommodating a plurality of audience members, and a view screen which is visible from the audience area;

    providing a video camera which is capable of recording digital video, the video camera being pointed at the audience area, the video camera being functionally connected to a computer for passing video data to the computer;

    wherein the computer comprises a memory and a processor, and wherein the computer is functionally connected to the view screen for displaying 3D video content on the view screen;

    the method further comprising;

    displaying 3D video content on the view screen, the video content on the view screen being at least partially controlled by the computer, the video content comprising simulation of movement through a 3D scenario from a first person perspective, said first person perspective being a camera view;

    the video camera capturing digital video of the audience area while the video content is presented on the view screen and while a plurality of audience members are in the audience area, the captured digital video comprising a chronological series of audience images, and the video camera passing the chronological series of audience images on to the computer;

    determining Optical Flow vectors for a plurality of different locations in each of the audience images, wherein Optical Flow vectors are determined by a process comprising comparing a location in an audience image with the same location in a chronologically earlier audience image to determine motion at that location;

    determining Motion Index values for a chronological series of audiences images, with Motion Index values being determined by a process comprising comparing a current Optical Flow vector with one or more previous Optical Flow vector;

    controlling rotation of the camera view using successive Motion Index values;

    wherein the 3D video content displayed on the view screen comprises at least one interaction item;

    the video camera capturing digital video of lateral gestures by a plurality of audience members in the audience area, the computer determining a plurality of Optical Flow vectors and a plurality of Motion Index values based on said digital video of lateral gestures, and rotating the camera view to one side in response to said Motion Index values;

    the interaction item moving from a side of the camera view to a center area of the camera view during said camera rotation, with the camera rotation stopping at a point where the interaction item is in the center area of the camera view in response to a plurality of audience members ending said lateral gesturing; and

    after the camera rotation stops, and in response to the interaction item remaining substantially in the center of the camera view for a threshold period of time, displaying a 3D animation of the camera view moving toward the interaction item on the view screen.
