A 4D theater enhances the traditional movie experience by adding physical effects that correspond with the on-screen action. This includes moving seats, wind, water sprays, and scents, creating a more immersive environment for viewers. The goal is to engage multiple senses, making the audience feel as if they are part of the film. These theaters often show action-packed films or animated features, where the added effects can heighten excitement and emotional responses. 4D technology is commonly found in theme parks and specialized cinemas, providing a unique way to enjoy movies beyond standard viewing.
