概括
指着手势指导视觉搜索,但不严格定义搜索区域. 搜索区域的大小受到显示密度的影响,而不仅仅是手势本身.
科学领域:
- 认知心理学 认知心理学
- 视觉感知 视觉感知 视觉感知
- 人与计算机的交互
背景情况:
- 指着手势对于将注意力转向对象至关重要.
- 了解手势如何影响视觉搜索对于人机交互和认知科学至关重要.
- 以前的研究表明,手势精确地标记了目标位置.
研究的目的:
- 调查指出手势是否定义特定的空间区域用于视觉搜索.
- 为了确定指针手势的感知位置是否决定了搜索区域.
- 探索显示密度对指向手势在指导视觉搜索中的有效性的影响.
主要方法:
- 用眼睛追踪进行了三项实验,以监测参与者的视觉搜索模式.
- 参与者在分散注意力的物体中寻找一个通过指向手势指出的目标物体.
- 干扰物体的空间密度在试验中系统地变化.
主要成果:
- 参与者确实在感知指点位置周围的受限制区域内进行了搜索.
- 搜索区域的大小受到显示器对象密度的显著影响.
- 指出手势严格定义搜索区域的假设被驳斥了,因为搜索区域是灵活的,有时可以扩展到指定的区域之外.
结论:
- 指着手势对搜索区域的大小的影响比以前假设的要弱或微不足道.
- 搜索区域的大小似乎是由灵活的标准决定的,可能与时间或时空相关,而不是固定的空间标记.

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Depth Perception and Spatial Vision
936
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

The Anchoring-and-Adjustment Heuristic

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...
