基于人脑相关模型的视觉时间和空间感(英文)

Neural-Based Theory of Temporal and Spatial Sensations of the Visual Field

一种典型的时间性的感觉是对于闪烁灯光缺失基频的现象.对此可用从信号的自相关函数(ACF)中导出的时间性因子加以描述.此方法与关于复音的音调评价所采用的方法相类似.此外,视觉的空间感,例如纹理感,包括对比、韵律和粗糙度,这些感觉也可用从灰度的ACF中导出的因子加以描述.其主观优选条件已经从其与时间和空间因子的关系中找出.文中还发现大脑的活动与对视觉有关的时间性因子的主观优选具有良好的对应性,当时间因子改变时,左脑的α波形更为显著.该理论结合时间和空间值可应用于实现更佳的视觉环境.此项关于时间性设计的新概念也可应用于建筑与环境设计中,人们可从2001年以来发表于网页http://www.jtdweb.org/中的文献里得到更多的关于JTD的信息.

The typical temporal sensation, a missing fundamental phenomenon of the flickering light, is described by the temporal factor extracted from the autocorrelation function （ACF） of the signal in the similar manner to the pitch of the complex tone. On the other hand, the visual spatial sensations known as a texture include contrast, regularity and coarseness. These sensations are described by the factor extranced from the ACF of the gray level. And, the subjectively preferred conditions are found in relation to the temporal and spatial factors. It is found that the brain activity well corresponds to the subjective preference in relation to the temporal factor of the visual field. With the change of temporal factors, the alpha wave on the left cerebral hemisphere is more significant. The proposed theory cooperating both the temporal and spatial values may be applied to the realization of an excellent visual environment. Moreover, such a new concept of the temporal design may be applied to the design of the architecture and the environment.
