Scenario

This report is evaluating the Samsung Galaxy S1 and use Apple iPhone4 as a comparison. In this report, heuristic evaluation method is used to evaluate Samsung Galaxy S1. I choose heuristic evaluation method instead of other methods because heuristic evaluation is easy to use as the observed problems are being explained by the established usability principle. It is also a better method for finding both major and minor problems in the human user interface when compared to other evaluation methods. It beings with the methodology and the heuristics utilities used in this report.
Then a detailed explanation of human interface problems identified by the heuristic utilities will be shown.

Methodology
The heuristic evaluation method is used to evaluate Samsung Galaxy S1 in this report. According to Jakob Nielsen stated “heuristic evaluation involves having a small set of evaluators examine the interface and judge its compliance with recognized usability principles” (Nielsen, 1993, p. 160). This method allows evaluators to discover the possible usability problems with just a short period of time. When evaluators use heuristic evaluation method, they can make a comparison between a pre-defined set of specific usability with a product interface that accomplish actual system task
