Check out this cool Orange Pulse Illusion. This Orange Pulse Illusion is an example of illusory motion which creates the perception that the design moves or pulses to some viewers.
Illusory motion refers to the perception of movement or motion where there is actually no physical motion occurring. It is a phenomenon in which static or stationary images, patterns, or stimuli give the impression of movement, leading to a perceptual illusion.

What is Orange Pulse Illusion?
The Orange Pulse Illusion is an example of Illusory motion.
Illusory motion refers to the perception of movement or motion where there is actually no physical motion occurring. It is a phenomenon in which static or stationary images, patterns, or stimuli give the impression of movement, leading to a perceptual illusion.
There are several types of illusory motion like the Orange Pulse Illusion:
- Motion Aftereffect (MAE): The motion aftereffect, also known as the waterfall illusion or the motion waterfall illusion, occurs when prolonged exposure to a moving stimulus followed by a stationary stimulus creates the perception of motion in the opposite direction. For example, after staring at a downward-moving waterfall for a while, when you shift your gaze to a static scene, you may perceive the stationary scene as moving upward.
- Phi Phenomenon: The phi phenomenon is a visual illusion where the perception of motion is created by presenting a series of stationary images in quick succession. This illusion is often used in motion displays, such as animated signs or displays, where a sequence of static images can give the impression of continuous motion.
- Autokinetic Effect: The autokinetic effect occurs when a single stationary light source in a dark environment appears to move or drift. This phenomenon happens due to involuntary eye movements and the lack of reference points in the visual field, causing the perception of motion in the absence of actual movement.
- Rotating Snakes Illusion: The rotating snakes illusion is a visual pattern where a series of circular shapes arranged in a specific manner can give the impression of rotating or swirling motion, even though the image is static. This illusion exploits the way our visual system processes edges and contours, creating the illusion of movement.
These are just a few examples of illusory motion phenomena. Illusory motion plays a significant role in studying perception, visual processing, and the mechanisms of how our brains interpret and construct motion perception.
How Does the Orange Pulse Illusion Work?
The Orange Pulse Illusion is an example of Illusory motion.
Illusory motion works by exploiting the mechanisms of our visual system and the ways in which our brains interpret and process visual information. Here are some explanations for a few common illusory motion phenomena:
- Motion Aftereffect (MAE): The motion aftereffect occurs due to neural adaptation. When we are exposed to a moving stimulus for an extended period, the neurons in the visual system that are responsible for detecting motion become fatigued or adapt to that specific motion direction. When the motion stops, the neurons that respond to the opposite direction of motion become relatively more active, resulting in the perception of motion in the opposite direction.
- Phi Phenomenon: The phi phenomenon relies on the perception of apparent motion. When a series of static images are presented rapidly and in close succession, our visual system integrates them and interprets them as continuous motion. The specific timing and spacing of the images can create the perception of motion between the discrete frames.
- Autokinetic Effect: The autokinetic effect is caused by involuntary eye movements and the absence of stable visual reference points. When we fixate our gaze on a single point of light in a dark environment, our eyes make tiny, involuntary movements. Due to the lack of external visual cues, these eye movements are interpreted by the brain as motion of the light source, leading to the perception of movement.
- Rotating Snakes Illusion: The rotating snakes illusion takes advantage of the way our visual system processes edges, contours, and the interactions between them. The arrangement of circular shapes and the specific pattern of contrasts in the image stimulate the motion-sensitive neurons in our visual system. This neural activity, combined with the way our brains process the contours and edges, leads to the perception of rotation or swirling motion.
In general, illusory motion occurs because our visual system relies on specific cues and processes to perceive motion, and certain visual stimuli can hijack or manipulate these processes, resulting in the perception of motion where there is none. These illusions provide valuable insights into the workings of our visual system and how our brains construct our perception of the visual world.
Some Similar Illusions
The Orange Pulse Illusion is an example of Illusory motion.
There are several fascinating illusions that are similar to illusory motion. Here are a few notable ones:
- Illusory Rotation: These illusions create the perception of rotation in stationary objects. Examples include the rotating snakes illusion and the spinning dancer illusion.
- Hering Illusion: The Hering illusion is characterized by the apparent curvature or bending of straight lines in certain patterns, typically radial or parallel lines.
- Ponzo Illusion: The Ponzo illusion is an optical illusion where two identical objects or lines appear to be of different sizes due to their placement within a converging context, such as railroad tracks.
- Müller-Lyer Illusion: This illusion involves the misperception of the length of lines with inward or outward arrowheads. Lines with outward arrowheads appear longer than lines with inward arrowheads, even though they are the same length.
- Kanizsa Triangle: The Kanizsa triangle is an example of an illusory contour illusion. It involves the perception of a triangle that is not explicitly defined by lines but rather by the configuration of surrounding elements.
- Motion Binding Illusion: This illusion occurs when stationary objects appear to move when surrounded by moving patterns or flickering stimuli.
- Adelson’s Checker Shadow Illusion: In this illusion, two squares of the same shade of gray appear different due to the influence of the surrounding checkerboard pattern and the presence of a shadow.
- Color Afterimage: Staring at a brightly colored object for an extended period and then shifting the gaze to a neutral background can create an afterimage of the complementary color.
- Neon Color Spreading: This illusion involves the perception of color spreading beyond the boundaries of an object onto a surrounding background.
- Ebbinghaus Illusion: The Ebbinghaus illusion demonstrates how the perceived size of a central object can be influenced by the size of surrounding objects.
These are just a few examples of illusions that share similarities with illusory motion. They showcase the intriguing ways in which our brains interpret and process visual information, leading to perceptual distortions and misperceptions.
