4D technology refers to the integration of the fourth dimension—time—into three-dimensional objects or experiences. This technology allows for dynamic changes in the structure or behavior of an object over time, enhancing how we interact with and perceive it. In various fields, such as architecture, medicine, and entertainment, 4D technology can create more immersive experiences. For example, in movies, 4D films combine traditional visuals with physical effects like motion seats and environmental elements, making the audience feel as if they are part of the action.
