How do we interact with Design?

The user interface is the in which people interact with a machine, device, or programme. In 'User interface design' (2005) Souren Lausen describes user interface as 'the part of the sysytem you see hear and feel.' The user interface also allows people to control a system by putting in information which responds to the person's activity. Interface design's such as the command line allowed people to type instructions for a machine to follow. The command line was a text only user face. This differs from the way people input information through graphical interface or using the mouse. The graphical user interface is more user friendly. Instead of text, the graphical interface uses graphical icons and visiual indicators, allowing people to interact with a system in more ways than than before. Graphical interface aslo developed the use of colours which can enhance a person's experience when using the design interface. The colour scheme for a site such a facebook is white and blue. The colour scheme for myspace is also white and blue, but allows people the option to change their background colour to create a new experience. The creation of the mouse pointer by Douglas Engelbart works with the graphical interface. Users are able to see the mouse as a cursor on the screen and are able to click on information created by links.

Handheld devices such as the iPhone has enhanced the interaction between people and mechanical devices. With the increase invention of the touch type screen feature, people are able to use their finger or a pen as a cursor to directly control what they see on the screen. They have the ability to control what they see even when they are on the go.
