Summary

Description

English: The Spinning Dancer is a kinetic, bistable optical illusion resembling a pirouetting female dancer. Some observers initially see the figure as spinning clockwise and some anticlockwise. Additionally, some may see the figure suddenly spin in the opposite direction. The illusion derives from an inherent ambiguity from the lack of visual cues for depth. There are other optical illusions that originate from the same or similar kind of visual ambiguity, such as the Necker cube.

Français : La danseuse en rotation, illusion d'optique créée par le web designer Nobuyuki Kayahara. Certains observateurs voient la figure tourner dans le sens horaire et d'autres dans le sens anti-horaire.

English: The Spinning Dancer is a kinetic, bistable optical illusion resembling a pirouetting female dancer. Some observers initially see the figure as spinning clockwise and some counterclockwise. Additionally, some may see the figure suddenly spin in the opposite direction. The illusion derives from an inherent ambiguity from the lack of visual cues for depth.

Other languages:

Dansk: Den dansende kvinde er en kinetisk synsbedrag, der opfattes som en kvindelig danser i piruet. Nogle mennesker ser først motivet, som om kvinden drejer med uret, andre at hun drejer mod uret. Desuden oplever nogle, at hun tilsyneladende pludselig skifter retning. Synsbedraget stammer fra en iboende tvetydighed, der skabes på grund af mangel på perspektiv og visuelle fikspunkter.

Additionally, some may see the figure suddenly spin in the opposite direction. The illusion derives from an inherent ambiguity from the lack of visual cues for depth.

Español: La Bailarina Girando es una ilusión óptica cinética multiestable que recuerda a una bailarina dando vueltas. Algunos observadores ven inicialmente a la figura girando en el sentido de las agujas del reloj, y otros en el inverso. Adicionalmente, algunos pueden ver de repente a la figura girando en la dirección contraria. La ilusión se debe a una ambigüedad inherente producida por la falta de pista visuales de la profundidad.

Français : La danseuse en rotation, illusion d'optique créée par le web designer Nobuyuki Kayahara. Certains observateurs voient la figure tourner dans le sens horaire et d'autres dans le sens anti-horaire.

Italiano: La ballerina girevole è un'illusione ottica cinetica e bistabile, simile ad una ballerina piroettante. Per alcuni osservatori la figura ruota in senso orario, per altri in senso antiorario. Inoltre alcuni la vedono improvvisamente ruotare in senso opposto. L'illusione deriva da un'inerente ambiguità dovuta dalla mancanza di indizi visuali sulla profondità.

Magyar: A pörgő táncos egy kinetikus, bistabil optikai csalódás mely egy piruettező női táncosra hasonlít. Egyes megfigyelők szerint (lásd az ábrát) az óramutató járásával megegyező irányban forog, mások szerint ellentétesen. Vannak olyanok is, akik szerint hirtelen megfordul az ellenkező irányba. Ez az illúzió is a rejtett kétértelműségből és a vizuális mélység hiányából ered. Sok más optikai illúzió eredete az azonos vagy hasonló jellegű vizuális kétértelműség, mint pl. a Necker kocka.

Nederlands: De draaiende danseres is een optische illusie van een vrouwelijke ballerina die pirouettes draait. Men kan haar zowel met de klok mee als tegen de klok in zien draaien.

Português: A Ilusão da bailarina é uma ilusão ótica de percepção multiestável do qual alguns observadores veem incialmente a bailarina girando no sentido horário enquanto outros veem no sentido anti-horário.

Русский: Оптическая иллюзия вращающейся танцовщицы

Українська: Танцівниця, яка крутиться — кінетична, бістабільна оптична ілюзія, що нагадує піруети танцівниці. Деякі спостерігачі бачать фігуру, яка обертається за годинниковою стрілкою, а деякі — проти годинникової стрілки. Крім того, деякі можуть раптом побачити зміну напрямку обертання. Ілюзія виникає з вродженої невизначеності через відсутність візуальних підказок для глибини зображення.

中文：旋转女舞者是一个多稳态知觉光学错觉现象，描绘了一个芭蕾女舞者。有些人看到人物是以逆时针方向旋转，另一个人则是顺时针。另外，有些人看到忽然反方向转动。这种错觉是由于缺少视觉深度引起的。
