Further, graphical elements sharing a single common color tone may create one or more of the illusions that may otherwise be enhanced by incorporating multiple color tones to the graphical elements creating the illusions. Exemplary consumer products include disposable diapers, feminine sanitary napkins, printed or electronic advertising media, and removable packaging enclosing articles prior to their use.

A 3D viewing system captures offset images from off-axis camera perspectives inclined to a normal of base plane of a scene that includes one or more objects projecting from the base plane. The offset images, which take a planar form, are displayed from a display surface at an off-axis viewing perspective that is inclined to a normal of the display surface similar to the inclination of the off-axis camera perspective to the normal of the base plane. The offset images undergo a distortion to counteract a keystone distortion associated with the off-axis viewing perspective. The base plane of the scene is oriented parallel to the display surface, and the objects projecting from the base plane appear to project from the display surface.

Provided are flying devices and methods of manufacturing and launching same, in particular flying toys or other recreational items that are designed to be thrown through the air by a user participating in any one of a variety of throwing (i.e. “catch”) games. In particular, the concept is directed toward a flying disc having rotatably attached non-rotating (a.k.a. “gliding”) portions that are attached to the disc and provide an optical illusion, wherein the user (and, similarly, an observer) does not notice the spinning of the flying disc, but instead sees a flying craft that appears to have no propulsion, yet flies. While the non-rotating portions alter the airflow associated with a typical flying disc, they do not negatively affect the flight characteristics of the disc itself. Indeed, in certain embodiments, the non-rotating portions (e.g., ailerons) have been observed to improve the flight characteristics of typical flying discs. The non-rotating portions (a.k.a. “gliding”) also provide surfaces upon which to place advertising that remains legible during flight. In this manner, the non-rotating portions of the flying device serve both a functional and an aesthetic purpose

The invention relates to a retro-reflection based arterial highway non-control intersection night-driving safety facility design method. Based on drivers' vibration perception and visual perception principle and by comprehensive application of involuntary speed reduction and voluntary speed reduction methods, in an intersection functional zone, seven road-surface lateral oscillation deceleration markings of 80-100m length at the vibrational frequency of 1-2 HZ are arranged such that a driver has a vibration discomfortableness so as to passively decelerate; frequency-conversion comb-teeth-shaped visual illusion deceleration markings of about 50m length at the median frequency of 4-8 HZ are arranged at the edge of a lane such that a speed that a driver senses is faster than an actual speed so as to actively decelerate; in an intersection physical zone, five intersection contour warning marks which are arranged 12-20m away from each other are disposed along the edge of a turning curve; and a retro-reflection material is used to design the deceleration markings and the warning marks such that night legibility and warning effect at intersections are raised. The design provided by the invention is suitable for arterial highway non-control intersections with the night travel-speed of 40-80km/h.

Disclosed is a urinal having an imaging device while not supplying washing water thereto. The urinal includes a main body having its front surface opened and a urine drainage hole provided at its lower portion, a recognition portion that senses a human body approaching the main body or a user's manipulation, and an imaging portion that displays a water flowing pattern image or a nature image inside or outside the main body when a human body approach signal or a manipulation signal is received from the recognition portion. According to the urinal having an imaging device, since an imaging portion is provided inside or outside the urinal, to which washing water is not supplied, an optical illusion may be cause to a user being accustomed to using a flushing type urinal so that the user is likely to believe that the urine is washed away even if urine washing water is not actually supplied to the urinal. Alternatively, while urinating, the user's feel of being refreshed can be maximized after urination by offering a carefree urination effect to the user so that the user may feel as if he were urinating in Mother nature.

A watercolor effect-added coloring picture 10 includes original image color areas 16 formed along linework areas 12 to be extended in a predetermined range from the linework areas 12 and filled with specified colors based on the colors of an original image, and blank areas 14 formed adjacent to the original image color areas 16. The linework areas 12 are filled with an achromatic gray color having a high luminance value, while the original image color areas 16 are filled with chromatic colors and are formed to have higher luminance values than the luminance value of the linework areas 12. This arrangement gives the watercolor effect as one illusion effect that creates the optical illusion of spread of a paler color over a neighboring area adjacent to a paler color line of two-color double lines. Although the blank areas 14 are actually not filled with any colors, the watercolor effect gives the illusion of the spread of the specified colors of the original image color areas 16 over the whole blank areas 14. The original image color areas 16 are formed in a width as narrow in width as the linework areas 12 and thus do not significantly disturb the user s coloring of the coloring picture 10 even with different colors from those of the original image.
