Task 1
Introduction
There are 4 ways mostly to evaluate user interface. Heuristic Evaluation (heuristically) by just looking at the interface and passing judgement according to one’s own view.Cognitive Walkthrough (analytical method) by some analysis procedure, Pluralistic Walkthroughs (empirically) by experiments with trial users, Feature, Consistency & Standards Inspection (automatically),by a programmed procedure. For this assignment I have choose the usability testing for empirical method where else for analytical method I have choose heuristic method.[1]

Analytical Method (Heuristic usability)
What is heuristic? “Heuristic evaluation is a discount usability engineering method for quick, cheap, and easy evaluation of a user interface design.” [3]
In heuristic evaluation the usability issues covered are effectiveness and efficiency but do not considered the satisfaction. Quantitative Data is not collected.this method also can be conducted remotely also can be used on any system.
Several evaluators independently evaluate the interface & come up with potential usability problems. It is important that there be several of these evaluators and that the evaluations be done independently. Nielsen's experience indicates that around 5 evaluators usually results in about 75% of the overall usability problems being discovered.

Heuristic Usability Principals
Here I am going to explain more and have a closer look at what condition are
