This paper reports on an empirical study that compares two sets of heuristics, Nielsenâ??s heuristics and the SMART heuristics in the\nidentification of usability problems in a mobile guide smartphone app for a living museum. Five experts used the severity rating\nscales to identify and determine the severity of the usability issues based on the two sets of usability heuristics.The study found\nthat Nielsenâ??s heuristics set is too general to detect usability problems in a mobile application compared to SMART heuristics which\nfocuses on the smartphone application in the product development life cycle instead of the generic Nielsenâ??s heuristics which focuses\non a wide range of interactive system. The study highlights the importance of utilizing domain specific usability heuristics in the\nevaluation process. This ensures that relevant usability issues were successfully identified which could then be given immediate\nattention to ensure optimal user experience.
