An essential part of our approach to designing Interactive system is that it should put people first it should be human centered. A Pact analysis is useful for both analysis and design activities understanding the current situation, situation, seeing where possible improvements can be made and envisioning future situations. The Pact Framework consist in four parts 1) People Interaction designers begin with the different among the users and their interactions. • Physical Differences Physical characteristics, e.g. height and weight Five sense, i.e. sight, hearing, touch smell and taste.

 Physical Differences
Physical characteristics,e.g.heightandweight
Five sense,i.e.sight,hearing,touchsmell andtaste.
 Mental Models

2. A personmental model (e.g.Norman,1998) of a device:if somethinggoeswrongthey
will notknowwhyandwill notbe able to recover.
