    It sounds like you are talking about Virtual Reality.

    "To look at" means to look straight at something.

    "To look around at" means to be able to look straight, left, right, behind you, etc.

    In Virtual Reality, you are just looking at a computer screen. So you are looking straight at something. But some systems let you "look around". You can turn your head left and right and see many other things.

    I hope that's what you meant.
