defiantly very high and system could be user friendly. The best way to deal such
problems are to test system frequently, ideally usability testing should be conducted to
enhance user friendliness. Usability testing is an emerging concept that ensures the high
standard of system usability, since traditional system testing approaches such as unit
testing, integration testing, user acceptance testing and automated testing does not cover
the scope of usability. Specially, WAP portals should be tested by usability testers.
In our second research question, we worked out twelve different factors that contribute
in user friendly m-commerce interface. In addition to our above discussion, these factors
could also be considered as guide for affective user interface design for mobile services.
On a higher level a combination of factors given in 1st research question and factors
given in 2nd research question could be used together since they have one common
“usability” factor. However, the factors given in 1st research question have emphasis on
“functions and operations” and factors given in 2nd research question have emphasis on
“user interface”. 96 7.2 Recommendations for Future Research Mobile commerce is one of the fastest and emerging fields of research. The importance
of mobile commerce is an open reality, however a few studies are found on “usability of
mobile commerce”. Therefore, this field of research required immediate attention of
passionate and enthusiastic researchers. Since, the mobile devices and technology itself
changing very quickly, as a result, it open doors for the constant need for the
improvement of mobile usability and mobile interface design principles. We would
recommend that a future study should be conducted by taking different sample selection
(WAP Portals). The study could be conducted by using Preset Tasks or with open ended
questionnaires. The objective of these Preset Tasks or questionnaires should be in depth
analysis of existing services and to figure out the potential areas of improvement in
WAP usability. Since, we believe that if mobile usability could be improved above
“satisfactory” level, it will have direct and positive impact of m-commerce usage and
increase in m-commerce business volume. 97 References:
