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.
