This practice was developed with the aim of supporting the user-centric design and avoiding to induce bias about the user interface in the early stage of the system specifications. [ 7 ] Use Case 2.0 to adapt the technique for the context of agile development methods. [ 1 ]

User analysis: This process is based around designing for the attributes of the intended user or operator, establishing the characteristics that define them, creating a persona for the user. [61] Best done at the outset of the design process, a user analysis will attempt to predict the most common users, and the characteristics that they would ...
The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size. A touchscreen enables the user to interact directly with what is displayed, instead of using a mouse, touchpad, or other such devices (other than a stylus, which is optional ...
