Breaking the Scalability Limit of Multi-Projector Calibration with Embedded Cameras

CVPR 2026 (Denver, USA)

Takumi Kawano, Kohei Miura, Daisuke Iwai

Since projectors do not have sensing capabilities, their calibration requires receiving the projector's light with another sensor. We propose a calibration method that uses cameras embedded in the calibration board as external sensors, allowing for a calibration process where the number of captures does not depend on the number of projectors.

Factors of player experience in describing the relationship between remade and original works

IEEE CoG 2024 (Milan, Italy)

Takumi Yokosaka, Kohei Miura, Yuko Isogaya, Tomoko Ohtani, Kazushi Maruya

Analyzed how players describe the relationship between original and remade games in terms of experiential factors. Showed the possibility of describing the consistency of works with experiential factors. This work was done during an internship at NTT laboratories.
