  Single-pixel imaging (SPI) is a novel optical imaging technique by replacing
a two-dimensional pixelated sensor with a single-pixel detector and pattern
illuminations. SPI have been extensively used for various tasks related to
image acquisition and processing. In this work, a novel non-image-based task of
playing Tic-Tac-Toe games interactively is merged into the framework of SPI. An
optoelectronic artificial intelligent (AI) player with minimal digital
computation can detect the game states, generate optimal moves and display
output results mainly by pattern illumination and single-pixel detection.
Simulated and experimental results demonstrate the feasibility of proposed
scheme and its unbeatable performance against human players.
