1. A method for generating an interactive space viewable through at least a first and a second device, the method comprising:

  • detecting from the first device a location of the second device or detecting from the second device a location of the first device, wherein the first device and the second device are handheld devices;

    exchanging synchronization information data between the first and second devices to identify a reference point in a three-dimensional (3D) space relative to a physical location of the first and second devices in the 3D space, wherein the first and second devices establish the physical location in the 3D space of the other device when setting the reference point; and

    generating views of an interactive scene in corresponding displays of the first and second devices, wherein the corresponding device acts as a camera viewing into the interactive scene, the interactive scene is tied to the reference point and includes virtual objects, each view showing all or part of the interactive scene and showing the interactive scene as observed from a current location of the corresponding device with a viewing angle of the corresponding camera, wherein device movement in the 3D space causes the corresponding view to change according to the current location and the viewing angle.
