Synthesized synchronicity mechanism for fitness-oriented virtual network game

Fitness-oriented virtual network game emerged along with the technology development of distributed virtual reality and its usage in game and sports. In particular, the synchronicity greatly affects the ability of game play. The factors that impact synchronicity are summarized in the paper, with the current algorithms divided into two categories, the conservative and optimistic. Based on the human visual perception ability, we present an adaptive synchronicity algorithm through altering the speed of objects. Techniques of interest management and dynamic user-list have been implemented on both sides of server and client to compensate network latency and reduce bandwidth requirements respectively. Experimental results of prototype validate the feasibility of this mechanism.
