All real-time computer games, particularly networked computer games, have a delay from when a player starts an action (e.g., clicking the mouse) until the game renders the result (e.g., firing a projectile). This delay can degrade both player performance (e.g., reduced game score) and quality of experience (e.g., the game is less fun). While previous work has studied the effects of delay on commercial games and individual game actions, a more detailed understanding is needed of the effects of delay on moving target selection with realistic target motion, a common scenario in many games. This paper presents an in-depth study of the effects of delay on the fundamental game action of selecting a moving target with a mouse while varying two parameters for the target motion – turn frequency and turn angle. We design and implement a custom game where players select moving targets using a mouse, while the game controls both the target motion and input delay. Analysis of data gathered in a 56-person user study shows both target selection time and accuracy degrade with delay. However, both selection time and accuracy increase with the frequency and angle of changes in the target’s movement, because turning slows targets down even while making them less predictable. We set these results in the context of other studies of delay and target selection by comparing our findings to those in seven other previously published papers that investigated the effects of delay on target selection.

运动和延迟对鼠标选择游戏目标的影响

所有实时计算机游戏,尤其是联网计算机游戏,从玩家开始动作(例如,点击鼠标)到游戏呈现结果(例如,发射弹丸)都有延迟。这种延迟会降低玩家表现(例如,降低的游戏分数)和体验质量(例如,游戏不那么有趣)。虽然之前的工作已经研究了延迟对商业游戏和单个游戏动作的影响,但需要更详细地了解延迟对具有现实目标运动的移动目标选择的影响,这是许多游戏中的常见场景。本文深入研究了延迟对用鼠标选择移动目标的基本游戏动作的影响,同时改变目标运动的两个参数——转弯频率和转弯角度。我们设计并实现了一个自定义游戏,玩家使用鼠标选择移动目标,而游戏同时控制目标运动和输入延迟。对 56 人用户研究中收集的数据的分析表明,目标选择时间和准确性都会随着延迟而降低。然而,选择时间和准确度都随着目标运动变化的频率和角度而增加,因为转动会减慢目标速度,即使目标变得更难预测。我们通过将我们的研究结果与其他七篇先前发表的研究延迟对目标选择的影响的论文中的研究结果进行比较,将这些结果设置在延迟和目标选择的其他研究的背景下。对 56 人用户研究中收集的数据的分析表明,目标选择时间和准确性都会随着延迟而降低。然而,选择时间和准确度都随着目标运动变化的频率和角度而增加,因为转动会减慢目标速度,即使目标变得更难预测。我们通过将我们的研究结果与其他七篇先前发表的研究延迟对目标选择的影响的论文中的研究结果进行比较,将这些结果设置在延迟和目标选择的其他研究的背景下。对 56 人用户研究中收集的数据的分析表明,目标选择时间和准确性都会随着延迟而降低。然而,选择时间和准确度都随着目标运动变化的频率和角度而增加,因为转动会减慢目标速度,即使目标变得更难预测。我们通过将我们的研究结果与其他七篇先前发表的研究延迟对目标选择的影响的论文中的研究结果进行比较,将这些结果设置在延迟和目标选择的其他研究的背景下。
