An electronic book, also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book",some e-books exist without a printed equivalent. E-books can be read on dedicated e-reader devices, but also on any computer device that features a controllable viewing screen, including desktop computers, laptops, tablets and smartphones.

Some new luminance-gradient effects - PubMed - The first effect concerns a brightness enhancement and a luminous mist spreading out from a central area having the same luminance as the white background and surrounded by four rectangular inducers shaded with a linear luminance gradient. The second effect is perceived with a photographically reversed configuration, and concerns what may be

Illuminating the Effects of Dynamic Lighting on Student Learning - The Effects of Lighting on Humans in General The human evolution is shaped by light. In the course of evolution, human beings have adapted and developed an internal clock that under natural light conditions is synchro-nized to the earth's 24-hr light-dark rotational cycle (Czeisler et al., 1999). Research reveals the mechanism for how light

Photosensitivity and Seizures | Epilepsy Foundation - Watch television in a well-lit room to reduce the contrast between light from the set and light in the room. Reduce the brightness of the screen. Sit as far back from the screen as possible. Use the remote control to change channels on the TV so you won't have to get too close to the set. Avoid watching for long periods of time

How Lighting Affects Mood - Illuminated Integration - Researchers believe that lighting levels make us perceive heat and make us feel warmer, causing our emotions to become more intense. The "hot emotional system" triggered by increasingly bright light can make us feel more strongly about our opinions and feelings. Bright light impacts both positive and negative emotions

The influence of depicted illumination on brightness | PNAS - The graphics used to test the perception of geometrical objects of known luminance in various scenes were created with a Powerwave 604/120 computer (Power Computing, Round Rock, TX), adobe illustrator 7.0 and photoshop 4.0 (Adobe Systems, Mountain View, CA), and studiopro 2.0 (Strata, George, UT). All cues about illumination were depicted so as to leave unaffected the contrast between the test

Luminance - Wikipedia - Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted from, or is reflected from a particular area, and falls within a given solid angle.. Brightness is the term for the subjective impression of the objective luminance measurement standard (see Objectivity (science

PDF Illuminance Versus Luminance - such that only a small amount of the light striking the surface in a direction away from the observer is reflected back toward the observer. The tail of the T always extends toward the observer regardless of his position on the roadway. The size, shape, and luminance of the T depends to a great extent on the surface characteristics of the pave

Relations between brightness and luminance under induction - The group consisting of the Relations between Brightness and Luminance under Induction 337 configuration used by HEINEMANN (1955) and the configuration gives lines with a slope at 25-30and crossing the 45median. This means, relatively speaking, that the higher the inducing luminance the lower the critical value

Why CFL's Aren't Such a Bright Idea | Psychology Today - Interestingly, the effects are non-visual, meaning they are caused by light signals that hit the eye's retina but that do not travel from there to the visual cortex (where we perceive images

Lighting and How it Affects on Your Mood - Examined Existence - Light does have an effect on a person's mood. The amount and wavelength of light affects the different functions of the brain, including the regulation of a person's thoughts and feelings. With this knowledge comes a realization that simple adjustments in lighting in homes and offices can make a lot of difference to the way a person thinks

Isolation of brightness induction effects on target patches from - The brightness (perceived intensity) of a region of visual space depends on its luminance and on the luminance of nearby regions. This phenomenon is called brightness induction and includes both brightness contrast and assimilation. Historically, and on a purely descriptive level, brightness contrast refers to a directional shift in target brightness away from the brightness of an adjacent

How Lighting Choices Can Affect Your Mood | Psychology Today - Natural light has the potential to enhance people's mood, creativity, and cognitive performance. Warm lighting can help create a cozy, social atmosphere, while cool lighting can help create an

Light & Sleep: Effects on Sleep Quality | Sleep Foundation - Some types have more illuminance and brightness. That said, even light that appears to have the same brightness may, in reality, have a different wavelength, changing how it's perceived by the eye and brain. ... C., Garbazza, C., & Spitschan, M. (2019). Effects of light on human circadian rhythms, sleep and mood. Somnologie : Schlafforschung

How glare causes visual discomfort | Philips lighting - Glare is a phenomenon caused by extremely bright light sources or by strong brightness contrasts in the visual field. (Brightness, for its part, is the perceptual sensation caused by a luminous source or reflecting surface.) Glare sources include windows, glossy magazine pages, computer screens, or incorrectly designed and installed artificial
