1. A method for generating an interactive space viewable through at least a first device and a second device, the method comprising: taking an image with a camera in the first device, wherein the first device and the second device are handheld devices; determining a relative position of the second device with reference to the first device based on image analysis of the image to identify a geometry of the second device; identifying a reference point in a three-dimensional (3D) space based on the relative position; and generating views of an interactive scene in corresponding displays of the first device and the second device, wherein the interactive scene is tied to the reference point and includes virtual objects, each view showing all or part of the interactive scene as observed from a current location of the corresponding device.
