Title: 7x7
Writing Type: Sketch / Art Talk
Exhibition: SIGGRAPH Asia 2017: Mind-Body Dualism

We live surrounded by displays such as TV, smartphone, computer. These bitmap displays consist of pixels arranged in a two-dimensional plane. 7×7 was created by re-arranging these pixels multidimensionally. This display consists of 49 pixels, and these pixels do not overlap in the front, at the back, up, down, left or right. Therefore, each pixel is able to represent all six directions. By using these 49 pixels, 7×7 expresses “Iroha,” which is an old Japanese pangram that expresses one of the aesthetics called “Mujo (impermanence and ever changing)”.

Title: Robotype: Studies of Kinetic Typography by Robot Display for Expressing Letters, Time and Movement
Writing Type: Paper
Exhibition: SIGGRAPH 2018: Original Narratives

Humans use letters, which are two-dimensional static symbols, for communication. Writing these letters requires body movement as well as spending a certain amount of time; therefore, it can be demonstrated that a letter is a trajectory of movement and time. Based on this notion, the author conducted studies regarding multidimensional kinetic typography, primarily using robots to display a letter and visualize its time and movement simultaneously. This paper describes
the project background and design of the three types of robotic displays that were developed and discusses possible expressions using robotic displays.
