Iconary: A Pictionary-Based Game for Testing Multimodal Communication with Drawings and Text
It addresses the problem of enabling AIs to communicate effectively with humans through multimodal gestures and semantics, presenting a novel benchmark for the research community.
The paper tackles the challenge of multimodal communication in AI by introducing Iconary, a Pictionary-based game that tests drawing and text interactions, and proposes models trained on over 55,000 human games that show skill but are outperformed by elite human players, particularly in drawing.
Communicating with humans is challenging for AIs because it requires a shared understanding of the world, complex semantics (e.g., metaphors or analogies), and at times multi-modal gestures (e.g., pointing with a finger, or an arrow in a diagram). We investigate these challenges in the context of Iconary, a collaborative game of drawing and guessing based on Pictionary, that poses a novel challenge for the research community. In Iconary, a Guesser tries to identify a phrase that a Drawer is drawing by composing icons, and the Drawer iteratively revises the drawing to help the Guesser in response. This back-and-forth often uses canonical scenes, visual metaphor, or icon compositions to express challenging words, making it an ideal test for mixing language and visual/symbolic communication in AI. We propose models to play Iconary and train them on over 55,000 games between human players. Our models are skillful players and are able to employ world knowledge in language models to play with words unseen during training. Elite human players outperform our models, particularly at the drawing task, leaving an important gap for future research to address. We release our dataset, code, and evaluation setup as a challenge to the community at http://www.github.com/allenai/iconary.
