Poster for the Cognitive Tools Lab at CogSci 2025, scheduled for Thursday, July 31. The poster is titled “Using gesture and language to establish multimodal conventions in collaborative physical tasks.” It features an image of a hand pointing to a 2×2 grid, with an arrow indicating movement from the bottom-left square to the top-left square. A quote reads, “... the green block pointing this way,” and the gesture is labeled “Complementary position & orientation.” Headshots of the four authors, Maeda, Tsai, Fan, and Abtahi, appear at the bottom. The session is listed as Poster Session 1 at 1:00 pm.
