概括

这项研究表明,视觉系统可以准确地计划眼睛的运动 (摇摆) 到纹理定义的目标. 萨卡德针对的是整个形状,而不仅仅是局部特征,纹理配置影响了规划时间.

科学领域:

视觉感知视觉感知视觉感知
眼神运动控制器的控制器
计算神经科学是一种计算神经科学.

背景情况:

目标的萨卡德定位是很好的研究,但对于纹理定义的数字来说不那么重要.
了解纹理信息如何引导眼睛运动对于视觉处理研究至关重要.

研究的目的:

研究如何处理纹理目标信息以控制眼动.
检查不同导向配置 (Block,Blur,Cornsweet) 在萨卡德规划中的作用.
为了确定萨卡德是否针对当地的突出区域或整个目标形状.

主要方法:

参与者对嵌入在背景结构中的纹理目标进行了冲刺.
测量了萨卡德着陆位置和延迟时间.
分析各种纹理定向配置 (Block,Blur,Cornsweet) 和它们的影响.

主要成果:

视觉系统有效地将纹理图形从地面分离出来,以便进行冲击规划.
随着纹理形状的变化 (Blur的最高),萨卡德延迟变化,但着陆位置仍然准确.
萨卡德指向目标的重心,区块配置文件产生最高的突出性.

结论:

眼睛的运动是基于整个目标形状表示的计划,而不仅仅是局部方向对比.
纹理形状会影响saccade编程时间,但不会影响最终的着陆精度.
这项研究阐明了复杂视觉目标的萨卡德定位背后的机制.

关键词:

Center of Gravity

Center of Gravity

The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...

Finding the Center of Gravity

Finding the Center of Gravity

The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...
