Abstract
Predictive contract mechanisms such as dead reckoning are widely employed to support scalable
remote entity modeling in distributed interactive applications (DIAs). By employing a form of
controlled inconsistency, a reduction in network traffic is achieved. However, by relying on the
distribution of instantaneous derivative information, dead reckoning trades remote extrapolation
accuracy for low computational complexity and ease-of-implementation. In this article, we present
a novel extension of dead reckoning, termed neuro-reckoning, that seeks to replace the use of
instantaneous velocity information with predictive velocity information in order to improve the
accuracy of entity position extrapolation at remote hosts. Under our proposed neuro-reckoning
approach, each controlling host employs a bank of neural network predictors trained to estimate
future changes in entity velocity up to and including some maximum prediction horizon. The effect
of each estimated change in velocity on the current entity position is simulated to produce an
estimate for the likely position of the entity over some short time-span. Upon detecting an error
threshold violation, the controlling host transmits a predictive velocity vector that extrapolates
through the estimated position, as opposed to transmitting the instantaneous velocity vector. Such
an approach succeeds in reducing the spatial error associated with remote extrapolation of entity
state. Consequently, a further reduction in network traffic can be achieved. Simulation results
conducted using several human users in a highly interactive DIA indicate significant potential
for improved scalability when compared to the use of IEEE DIS standard dead reckoning. Our
proposed neuro-reckoning framework exhibits low computational resource overhead for real-time
use and can be seamlessly integrated into many existing dead reckoning mechanisms.
