The wallpaper illusion explained.
In the wallpaper illusion, a repetitive pattern appears to shift from one depth plane to the plane nearest fixation. We measured the timing of this shift for a 6 degrees wide, 3-cpd sinusoidal grating presented in a rectangular envelope; the edges (envelope) of the grating were presented at 20 arcmin of disparity (one period) behind the fixation plane. We asked observers to signal when the segm...
متن کاملWallpaper illusion: cause of disorientation and falls on escalators.
The wallpaper illusion, first described over a century ago, can occur when a person with normal binocular vision views a pattern that is periodic in the horizontal meridian of the visual field. Escalator trends present such a pattern. Evidence is presented favoring the view that disorientation experienced by escalator riders is caused by this illusion. Possibly some of the estimated 60,000 esca...
متن کاملThe Poggendorff illusion explained by natural scene geometry.
One of the most intriguing of the many discrepancies between perceived spatial relationships and the physical structure of visual stimuli is the Poggendorff illusion, when an obliquely oriented line that is interrupted no longer appears collinear. Although many different theories have been proposed to explain this effect, there has been no consensus about its cause. Here, we use a database of r...

The colour of the wallpaper in this project changes with the sound of the environment. The original colour of the wallpaper is blue, as the noise of the environment increases, the colour changes to warmer colour to the extent of red. With this effect, the wallpaper brings attention to the noise level of the room and encourages users to decrease the sound level of their conversations. The transf...
متن کاملWallpaper Maps
A wallpaper map is a conformal projection of a spherical earth onto regular polygons with which the plane can be tiled continuously. A complete set of distinct wallpaper maps that satisfy certain natural symmetry conditions is derived and illustrated. Though all of the projections have been published before, the family had not been characterized as a whole. Some wallpaper maps generalize to one...
