A physics-aware dead reckoning technique for entity state updates in distributed interactive applications

This paper proposes a novel entity state update technique for physics-rich environments in peer-to-peer Distributed Interactive Applications. The proposed technique consists of a dynamic authority scheme for shared objects and a physics-aware dead reckoning model with an adaptive error threshold. The former is employed to place a bound on the overall inconsistency present in shared objects, while the latter is implemented to minimise the instantaneous inconsistency during users´ interactions with shared objects. The performance of the proposed entity state update mechanism is validated using a simulated application.
