      今日はネットで作品を調べものも同時にしていました。The montalvo illusion (lavatory wall illusion)で調べると北岡先生の論文も見つけました。やー、やっぱり北岡先生の過去の業績スゴイですねー!! https://www.researchgate.net/publication/12795656_Apparent_contraction_of_edge_angles … https://onlinelibrary.wiley.com/doi/full/10.1111/j.1468-5884.2007.00328.x … http://www.psy.ritsumei.ac.jp/~akitaoka/4-stroke-tilt-and-motion.html …

      これはデモというわけではないのですが、「今日はこんな事をしましたー!」という報告です。 例の背景色を作ってから、グラデーションの正方形を並べました。紫色は少し地味っぽくてインパクト無いかな?pic.twitter.com/o0sRYXGf6W

      この絵ですと、モンタルボ錯視の仲間とは言いにくいです。新しい絵画的配置(デザイン)だ、と言っているのですよ。

      モンタルボ錯視は、境界線(被誘導線、カフェウォール錯視ならモルタル線とも)として、グラデーションの最大の明あるいは暗の境界線を使います。この刺激配置での錯視作用ポイントは、添付図の右下のものと思います。 (Kitaoka et al., 2004)pic.twitter.com/5fFOTIkcmN

      そのほか、静止画が動いて見える錯視がありますね。グラデーションの勾配の中で、コントラストは低くて暗い領域から、コントラストは高くて明るい領域の方向に動いて見え、かつ中心視でも動いて見えます。「中心ドリフト錯視」かな。pic.twitter.com/Xxk0T8z4qt
