Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

10.4K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Perceptual Constancy01:12

Perceptual Constancy

1.7K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Design Example: Resistive Touchscreen

815
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Color Vision01:24

Color Vision

1.8K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Dark Triad and Person Perception01:29

Dark Triad and Person Perception

361
Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et...

Anatomy of the Eyeball01:20

Anatomy of the Eyeball

11.0K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

    Summary
    This summary is machine-generated.

    Researchers studied black perception on transparent OLED displays. Transparency made displays appear darker, an effect termed "Transparency Effect," and background brightness influenced perceived blackness.

    Area of Science:

    • Visual perception
    • Display technology
    • Human-computer interaction

    Background:

    • Accurate black level perception is crucial for display quality.
    • Transparent OLED displays present unique challenges for visual perception due to their see-through nature.

    Purpose of the Study:

    • To investigate the perception of blackness (gray 0) on transparent OLED displays.
    • To quantify the impact of transparency on perceived black levels.
    • To analyze how background luminance affects the perception of black on transparent displays.

    Main Methods:

    • A pre-test established maximum acceptable black level luminance under various surround conditions using a non-transparent display.
    • Experiment 1: Compared perceived blackness of transparent versus opaque patches at similar luminance levels.
    • Experiment 2: Assessed perceived brightness of gray 0 under varying background luminance conditions on transparent OLEDs.

    Main Results:

    • Participants perceived transparent patches as darker than opaque patches of similar luminance, a phenomenon termed the 'Transparency Effect'.
    • Increased background luminance generally led to darker perceived black levels (gray 0) on transparent OLEDs, though individual responses varied.
    • The transparency of the display acted as a window, influencing perception based on the overlapped background.

    Conclusions:

    • Transparency inherently affects perceived blackness, making displays appear darker.
    • Background luminance significantly modulates the perceived black level on transparent OLED displays.
    • Understanding the 'Transparency Effect' is vital for optimizing visual experience and image quality in transparent display applications.
