Preface...

I have been studying usability issues for many years. I have read a lot of influential writings. Those are inspiring no doubt, in most of the cases the fame of the author swiped off the original fact of usability rather have argued for lack of usability in things in daily live. This book is not all the a row, rather the author has been trying to be neutral, he also tried to thing from the designer point of view as well as the user experience. A simple but prominent example is, if some one just got a chance to sit on the pilots seat in a MIG-29, should he supposed to understand anything? Unfortunately many famous authors have not considered this issues, the user should fulfill some requirement. Many observers with their lack of knowledge within a correct domain argued for lack of usability. A simple door key to lock the door requires some primary knowledge about door, key or how tos. Not all the doors in the universe are issues of usability discussion. We have reached in such a time, usability engineer should have self realization, criticism; it is the hight time.
