News Finding: The model predicts the players' task success rate when latency is added to the gaming environment.
Paper Finding: The new model built on these assumptions accurately predicts the effect of end-to-end latency on user error rate for the task.
News Context: This cognitive model is capable of predicting the success rate of a user when there is latency in a 'moving target selection' task which requires button input in a time constrained situation. The model predicts the players' task success rate when latency is added to the gaming environment. In fact, this research succeeded in modifying the pillar heights of the Flappy Bird game, allowing the players to maintain their gaming performance regardless of the added latency.
Paper Context: For a moving-target selection task with zero latency, a model for predicting the user's error rate already exists . The new model built on these assumptions accurately predicts the effect of end-to-end latency on user error rate for the task. When geometric compensation is applied, the model can predict the corresponding error rate, thereby facilitating control of game difficulty level when latency exists.
