1. A method for displaying a simulated collision between a real object and a virtual object using a see-through augmented reality display device comprising: for real and virtual objects present in a displayed field of view of the see-through augmented reality display device, identifying at least one collision between a first real object having one or more parts that are viewable through a see-through portion of the see-through augmented reality display device and a first virtual object based on respective three dimensional (3D) augmented reality space positions associated with the first real and virtual objects; determining at least one virtual-world deformative effect to be virtually imparted to a part of the first real object due to the virtual space collision based on one or more of determined pre-collision physical properties assigned to respective parts of the first real object and of determined physical interaction characteristics for the collision; generating image data for the first real object simulating the at least one virtual-world deformative effect as having been virtually imparted to a collision affected part of the first real object, where the collision affected part of the first real object is not actually deformed by the collision with the first virtual object; and displaying the generated image data including the at least one deformative effect virtually imparted to the collision affected part of the first real object using the see-through augmented reality display device, where the generated and displayed image data of the collision affected part is registered to a location of the first real object as seen using the see-through augmented reality display device.
