Visual feedback (also called optical feedback) is:
- visual output from a system such as a video game that allows the user to interact better with the system. An example is when playing a video game the images on the television or computer screen are the visual feedback of the system.
- created when the recording device such as a camera is pointed at the screen or monitor that is displaying the recorded information. This process creates slightly smaller images that continue onto infinity. The same effect can be created with two rows of mirrors facing each other with the observer in the middle.
