Robotic painting has been a subject of interest among both artists and roboticists since the 1970s. Researchers and interdisciplinary artists have employed various painting techniques and human-robot collaboration models to create visual mediums on canvas. One of the challenges of robotic painting is to apply a desired artistic style to the painting. Style transfer techniques with machine learning models have helped us address this challenge with the visual style of a specific painting. However, other manual elements of style, i.e., painting techniques and brushstrokes of an artist, have not been fully addressed.We propose a method to integrate an artistic style to the brushstrokes and the painting process through collaboration with a human artist. In this paper, we describe our approach to 1) collect brushstrokes and hand-brush motion samples from an artist, and 2) train a generative model to generate brushstrokes that pertains to the artist's style, and 3) fine tune a stroke-based rendering model to work with our robotic painting setup. We will report on the integration of these three steps in a separate publication. In a preliminary study, 71% of human evaluators find our reconstructed brushstrokes are pertaining to the characteristics of the artist's style. Moreover, 58% of participants could not distinguish a painting made by our method from a visually similar painting created by a human artist.

Imago is an interactive system representing an "alien" that has a unique communication method of movie projection. Imago's body consists of projector turning, projection and human detection system using ultrasonic sensors. Imago projects its messages in the form of movies on the participant's body in response to their position and speed. Imago aims not to make a system simulating human gesture detection, but to represent the communication situation between two creatures having different/limited communication ways as artwork. Participants experience the Imago's method of communication and ruminate human communication requiring efforts to understand differences. Furthermore, Imago is expected to evoke image communication, which has been less emphasized since Gutenberg Galaxy [1], in the participant's mind.
