What term is used for an action that can enhance the illusion of a character's movement on stage?

The term that best describes an action enhancing the illusion of a character's movement on stage is "cheat." In theatrical terminology, to "cheat" often refers to the practice of positioning oneself or performing actions slightly off from the natural or realistic way in order to create a stronger visual impact for the audience. By "cheating" a movement, an actor can make their actions more visible or exaggerated, thus effectively communicating the intention behind their character's movement without breaking the flow of the performance.

In the context of theater, this technique can be essential for maintaining the dynamics of physical storytelling, ensuring that movements are perceived clearly from various audience viewpoints. This enhances the overall theatrical experience by allowing the audience to engage more fully with the performance, creating a seamless illusion of reality.
