我们调查了眼动类的自然和动态设置的组织。为了在受控环境中模仿自然世界的目标和目的，我们研究了参与者玩Breakout时的眼球运动，Breakout是一款古老的Atari游戏，尽管其图形和结构简单，但仍然令人惊讶地有趣，经常上瘾。我们的研究结果表明，眼动动力学可以解释的预测和行动的紧迫性时刻的简单原则。我们观察到了一致的预期行为（目光指向球的轨迹前方），除了在球在墙上反弹或在球拍上反弹的那一刻。在这些时刻，我们观察到一个不应期，在此期间没有眨眼和扫视。扫视延迟导致视线落在球后面。这种模式是一致的模型，通过该模型，参与者推迟扫视在弹跳，同时预测球的轨迹，随后作出追赶扫视指向的位置，预计球的轨迹。在弹跳过程中，轨迹是平滑的，弯曲的，以最小的加速度插值球的V形函数。这些结果铺平了道路，以了解分类的眼动自然配置中的刺激和目标切换动态的时间。(C)2011爱思唯尔有限公司版权所有。
We investigated the organization of eye-movement classes in a natural and dynamical setup. To mimic the goals and objectives of the natural world in a controlled environment, we studied eye-movements while participants played Breakout, an old Atari game which remains surprisingly entertaining, often addictive, in spite of its graphic and structural simplicity. Our results show that eye-movement dynamics can be explained in terms of simple principles of moments of prediction and urgency of action. We observed a consistent anticipatory behavior (gaze was directed ahead of ball trajectory) except during the moment in which the ball bounced either in the walls, or in the paddle. At these moments, we observed a refractory period during which there are no blinks and saccades. Saccade delay caused the gaze to fall behind the ball. This pattern is consistent with a model by which participants postpone saccades at the bounces while predicting the ball trajectory and subsequently make a catch-up saccade directed to a position which anticipates ball trajectory. During bounces, trajectories were smooth and curved interpolating the V-shape function of the ball with minimal acceleration. These results pave the path to understand the taxonomy of eye-movements on natural configurations in which stimuli and goals switch dynamically in time. (C) 2011 Elsevier Ltd. All rights reserved.
