Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.5K
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.

Selected Data About Geographic Locations

312
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

443
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Coordinates and Map Projections01:29

Coordinates and Map Projections

758
Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...

Position and Displacement Vectors

14.2K
To describe the motion of an object, one should first be able to describe its position (where it is at any particular time). More precisely, the position needs to be specified relative to a convenient frame of reference. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference to describe the position of an object in relation to stationary objects on Earth.
Further, several important kinds of...

Gestalt Principles of Perception01:21

Gestalt Principles of Perception

1.7K
Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Visual Perception

Background:

  • Spatial memory and reasoning depend on allocentric representations.
  • The construction of these spatial representations, particularly early stages, is not well understood.
  • It is unclear if pre-attentive spatial processing is innate or shaped by experience.

Purpose of the Study:

  • To investigate whether early, pre-attentive spatial processing can be altered by experience.
  • To examine the malleability of spatial representation formation.

Main Methods:

  • Participants viewed briefly presented (53 ms) masked visual stimuli with a target and reference features.
  • The location of the feature array was shifted.
  • Participants identified the target's new relative location.

Main Results:

  • Experience altered feature processing, even with sub-saccadic display durations.
  • This occurred before attention could be re-allocated.

Conclusions:

  • Early perceptual processes are crucial for creating spatial location representations.
  • These processes are adaptable and influenced by experience and expectations.
