Three types of information is represented in information systems.
   •  Functional information
   •  Augmented information
   •  Inherent information results
Functional information:
A direct result of the product’s function (e.g. over door swings open on the pulling the handle down)

Augmented information:
Informs the user about internal state of the product (e.g. LED lights up the indicate the oven warms up)

Inherent information results:
Information results directly from the user’s actions. (e.g. the feeling of a button pressed down and hearing it clicking)

This information is presented through various output media. Multiple possibilities such as images, 3D models, live video and dynamic graphics are presented through screen. Other possibilities such as color (through LEDs), light and change in material properties can also be used to provide intermediate and final digital information.
