Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

850
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.

Influence of Earth's Curvature and Atmospheric Refraction on Leveling01:26

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

234
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.

Computed Tomography01:10

Computed Tomography

5.5K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Calibration Curves: Linear Least Squares01:20

Calibration Curves: Linear Least Squares

1.8K
A calibration curve is a plot of the instrument's response against a series of known concentrations of a substance. This curve is used to set the instrument response levels, using the substance and its concentrations as standards. Alternatively, or additionally, an equation is fitted to the calibration curve plot and subsequently used to calculate the unknown concentrations of other samples reliably.
For data that follow a straight line, the standard method for fitting is the linear...

Unsoundness of Aggregate due to Volume Change01:26

Unsoundness of Aggregate due to Volume Change

167
Unsoundness in aggregates due to volume changes is primarily caused by the physical alterations aggregates undergo, such as freezing and thawing, thermal changes, and wetting and drying. Unsound aggregates, when subjected to these changes, result in volume change upon disintegration. This, in turn, contributes to the deterioration of concrete, including scaling, pop-outs, and cracking. Particular types of aggregates, such as porous flints, cherts, and those containing clay minerals, are...

Uniform Depth Channel Flow: Problem Solving01:18

Uniform Depth Channel Flow: Problem Solving

121
To calculate the flow rate for a trapezoidal channel, first, identify the bottom width, side slope, and flow depth of the channel. The cross-sectional area (A) corresponding to the depth of flow (y), channel bottom width (B), and side slope (θ) is determined by:Next, calculate the wetted perimeter, which includes the bottom width and the sloped side lengths in contact with the water. Using the values of the cross-sectional area and the wetted perimeter, determine the hydraulic radius by...

    Area of Science:

    • Human-Computer Interaction
    • Cognitive Psychology
    • Virtual Reality

    Background:

    • Previous studies on depth perception and sensorimotor calibration often used single-session designs.
    • Limited research has explored the impact of prior experience, in-session learning, and longitudinal calibration on VR spatial perception.

    Purpose of the Study:

    • To empirically evaluate how longitudinal calibration influences perception-action coordination over time in novice virtual reality (VR) users.
    • To investigate changes in depth perception and distance estimation within a virtual environment as users gain experience.

    Main Methods:

    • Recruited novice VR users for an 8-session depth perception reaching experiment spanning 12 weeks.
    • Monitored and analyzed changes in participants' ability to estimate depth in a virtual environment throughout the study duration.

    Main Results:

    • Novice VR users demonstrated a diminishing underestimation of distances over time.
    • Increased experience in the virtual environment correlated with improved depth perception and reduced spatial errors.

    Conclusions:

    • Longitudinal calibration significantly impacts spatial perception and perception-action coordination in long-term VR experiences.
    • Future VR research should incorporate longitudinal designs to capture the effects of user experience and calibration over time.
