Here are some examples:
* "The audience was riveted by the magician's performance." This means the audience was completely captivated and absorbed by the show.
* "She was riveted to the news, unable to look away." This means she was intensely focused on the news, unable to break her concentration.
* "His eyes were riveted on the horizon, searching for the approaching ship." This means he was looking intently at the horizon, completely focused on finding the ship.
It's important to note that "riveted" is often used figuratively, meaning the person isn't literally being held by a rivet, but rather they are mentally or emotionally fixated on something.
