TL;DR: Drawing Dialogues between Humans and AI

Abstract: We introduce Pareiduo, an interactive device that facilitates drawing games between humans and AI. Drawings are a fundamental human artifact and a new way for AI to understand abstract representations. Pareiduo encourages players to sketch in sand on a glowing surface with feedback and instructions driven by LLMs. Two players take on complementary roles: Shadow (handling sand formations) and Light (dealing with voids), working together to help the AI identify their creations. The system combines visual intelligence, image processing, and embedded electronics to offer a screen-free, multisensory interface that promotes face-to-face interaction. Pareiduo reimagines human-AI perceptual differences not as mistakes but as reflections of the variety within abstract representation. The project explores the creative space where human imagination and machine perception meet in an open-ended conversation, sparking reflections on representation, standardization, and teamwork in the digital age.
