In this paper we assess the impact of head movement on user's visual acuity and their quality perception of impaired images. There are physical limitations on the amount of visual information a person can perceive and physical limitations regarding the speed at which our body, and as a consequence our head, can explore a scene. In these limitations lie fundamental solutions for the communication of multimedia systems. As such, subjects were asked to evaluate the perceptual quality of static images presented on a TV screen while their head was in a dynamic (moving) state. The idea is potentially applicable to virtual reality applications and therefore, we also measured the image quality perception of each subject on a head mounted display. Experiments show the significant decrease in visual acuity and quality perception when the user's head is not static, and give an indication on how much the quality can be reduced without the user noticing any impairments.

用户动态视力和受损图像质量感知的探索性研究

在本文中，我们评估了头部运动对用户视力及其对受损图像质量感知的影响。一个人可以感知的视觉信息量存在物理限制，而我们的身体以及因此我们的头部探索场景的速度也存在物理限制。这些限制在于多媒体系统通信的基本解决方案。因此，当他们的头部处于动态（移动）状态时，受试者被要求评估电视屏幕上呈现的静态图像的感知质量。这个想法可能适用于虚拟现实应用，因此，我们还在头戴式显示器上测量了每个对象的图像质量感知。实验表明，当用户使用时，视力和质量感知显着下降。
