What are the distinct characteristics of installation art?

Installation art is characterized by its immersive, site-specific nature, often transforming a space into a cohesive experience that engages the viewer physically and emotionally. It commonly incorporates a variety of materials, including sculpture, video, sound, and found objects, allowing for a multi-sensory experience. Unlike traditional art forms that are typically viewed from a distance, installation art invites active participation and exploration, often encouraging interaction with the environment. Additionally, it may address themes related to social, political, or environmental issues, prompting reflection and dialogue.
