Overview

Problem Statement

Effects of unintended latency on gamer performance have been reported. End-to-end latency can be corrected by post-input manipulation of activation times, but this gives the player unnatural gameplay experience.

Solution

We first built and validated a predictive model that can predict user performance in MTS (moving-target selection) tasks. Using the novel model, we developed a novel compensation method for the latency effects by adjusting the game's geometry design. Our method can keep the user's error rate constant even if the end-to-end latency of the system changes.
