Abstract: The theoretical study of chiral particles provides an ideal model for understanding non-equilibrium physics, revealing how microscopic chirality drives the rich collective behaviors of active matter. In theoretical research, the chirality of active particles is usually incorporated into dynamic equations by using a rotational angular velocity or torque. This paper departs from this traditional method. Instead, it introduces visual perception alignment to explore a possibility: Active particle systems can exhibit chiral characteristics through visual functions, and this phenomenon implies a different mechanism of chiral symmetry breaking. This offers an alternative perspective for deeply understanding the origin of chirality in active particles and their physical essence. It is found that there are three phase states in the visual perception system: the radial convergence, the spiral migration, and the mass migration states. Additionally, this paper quantitatively studies the dependence of the angular velocity ratio of active particles on parameters such as visual direction, concentration, system size, and environmental factors, providing technical references for the precise control of the chirality of active particles.
