沉浸式显示器允许在宽视场上呈现丰富的视频内容。我们提出了一种方法，以提高视觉重要性的一个选定的-可能是不可见的-场景的一部分，在一个混乱的虚拟环境。该期望的特征使得能够不引人注目地将用户的注视方向引导到沉浸式360°周围环境内的任何位置。我们的方法是基于微妙的视线方向，其中不包括头部旋转在以前的工作。为了覆盖整个360°环境和宽视场，我们提供了一种基于偏心率的动态刺激定位和形状变化的方法，以补偿整个视场的可见度差异。我们的方法是校准的头戴式显示器与双目眼跟踪的感知研究。另一项研究验证了沉浸式视觉搜索任务中的方法。
Immersive displays allow presentation of rich video content over a wide field of view. We present a method to boost visual importance for a selected - possibly invisible - scene part in a cluttered virtual environment. This desirable feature enables to unobtrusively guide the gaze direction of a user to any location within the immersive 360° surrounding. Our method is based on subtle gaze direction which did not include head rotations in previous work. For covering the full 360° environment and wide field of view, we contribute an approach for dynamic stimulus positioning and shape variation based on eccentricity to compensate for visibility differences across the visual field. Our approach is calibrated in a perceptual study for a head-mounted display with binocular eye tracking. An additional study validates the method within an immersive visual search task.
