Well known concept in the science of control and information theory. As number of features increase, the use of feedback diminished Feedback can be presented visually or aurally. It may cost more to develop a complex phone with good feedback, but the trade-off is increase in usability. Today's devices and computer systems are commonly developed with many, many, features. Good design requires that the designer think about how people will use the device how people will abuse the device the kinds of errors people will make and the tasks and functions people will wish to perform The Paradox of Technology Advances in technology offers the potential to make our jobs more productive, and our lives easier and more enjoyable.
Advances can also introduce added complexity, which can increase our difficulty and frustrations.
This paradox in technology is not an excuse for a poor design. Instead, principles of good design can be used to manage complexity. More easily said than done. Good design takes careful thought, planning, and hard work.
