Forked! A demonstration of physics realism in augmented reality

In making fully immersive augmented reality (AR) applications, real and virtual objects will have to be seen to physically interact together in a realistic and believable way. This paper describes Forked! a system that has been developed to show how physical interactions between real and virtual objects can be simulated realistically and believably through appropriate use of a physics engine. The system allows users control a robotic forklift to manipulate virtual crates in an AR environment. The paper also describes a evaluation experiment in which it is shown that the physical interactions between the forklift and the virtual creates are realistic and believable enough to be comparable with the physical interactions between a forklift and real crates.
