The demo presentation “Superimposed QR Code Attack Using LED Displays” by Keita Suzuki et al., given at the IPSJ Symposium “INTERACTION 2026” held March 3β5, 2026, received the Interactive Presentation Award in both the PC Recommendation and Audience Vote categories.
This research proposes a new disguised QR code attack using LED displays. By applying the superimposed QR code attack β which exploits the difference between human visual perception and camera imaging characteristics β to LED displays, the constraints on code modification that existed with LCD displays are removed, enabling more flexible tampering and further strengthening the attack.

The PC Recommendation category is selected by the INTERACTION 2026 Program Committee, while the Audience Vote category is determined by votes from all participants of INTERACTION 2026.
