In recent years, the well-developed Vicsek model (VM) has attracted more and more attention. In this paper, a novel modified VM is proposed in order to describe the collective motion of the self-propelled particles, wherein the particles have the restricted visual field and the changing line of sight (LoS). The attention field (or field of view) of each particle is a sector, and the LoS direction randomly changes around the direction of motion, in which the changing ruler follows the normal distribution. Compared with the original Vicsek model, the proposed model is more close to the reality. Simulations are performed, and the results show that the proposed modified model can accelerate the synchronization speed and enhance the robustness.
