In this paper we propose a method that produces a 2D image that can self-contain physical information such as the object geometry. To associate additional physical information with digital images, we employed a steganography method that exploits the low sensitivity of human beings to high-frequency brightness variations. With the proposed method, 2D images can have its own tactility. The main advantage of this method over previous information-handling methods is that the resultant format remains compatible with an ordinary 2D image. For example, if the original image is a PNG file, the resulting image can remain as a PNG file. We conclude with explorations of geometry-based interactive applications and discussions on compatibility and transparency issues.
