Unformatted text preview: hile clicking on any video, none of the
videos execute, even it could not produce any error. This problem could also be
eradicated, if portal could be tested by professional testers from time to time.
The task-8 in CNN, when users attempt to choose sports score of their choice, instead of
showing “sports list” they found “Search Box” where they have to type sports name to
get result. In this case, the designers should keep in mind that typing on keyboard and
typing on mobile is not same thing. Typing letters using mobile device consumes 94 reasonable amount of time which is strictly against usability principles. Therefore, the
problem can be solved simply by offering “sport lists”.
It is observed that there are many errors that can easily be eliminated just with little
efforts. For example, in task-13 of Amazon, the users tried to seek “GPS” under
Electronic category. The users entered GPS in “Search” option to obtained result,
however the results were misleading, since no sorting or indexing method was used for
product listing. On first page portal shows Garmin and TomTom respectively.
Generally, product lists are arranged in ascending order, hence it misleads the customer
that just one Garmin GPS is available followed by TomTom GPS. However, in page
two portals again shows two more Garmin GPS and TomTom GPS again. Such, errors
could be controlled if portal could be reviewed or analyzed periodically. In addition,
there is an increasing need for WAP portals to make portals easy to access and fast to
down load, therefore companies should avoid using high graphics and images, which
took extra time in down load pages. Task-5 in CNN is an example of heavy images that
caused slow downloading speed.
In order to answer our first research question, we worked out eighteen different factors
that affect the quality of WAP services, these factors are based on the highly valuable
research of world renewed researchers. Therefore we believe that, if these factors are
correctly considered while preparing a new WAP service, it would certainly be act as a
good guide for WAP service designers. 7.1.2 RQ 2. How the m-commerce interface design can be made
user-friendly? An effective user friendly interface design plays central role in the success of mobile
commerce. It is important to note that the increased functionality should not be used as
an excuse for poor interface design. It is possible to design good interfaces in which
different system features can be controlled effectively that can provide useful and quick
response. In our study, our both sample WAP portals possess good and user friendly
interface design. However, while conducting our research, we figure out some potential
areas that require improvement in order to enhance the friendliness of m-commerce
As a thumb rule for user-centered design, the user and user issues should be put in
centre in the design process. Total system functions should be designed to meet user
requirements, user learning and efficient user access. Since, user is the ultimate
“Consumer” of the service, therefore easy to understand syntax and “user language”
should be used in the system. For instance, in task-12 of Amazon portal, when “Product
Details” explored, we got totally irrelevant and inappropriate information which caused 95 frustration at first place, and reveals the carelessness of interface design at second place.
Since, we observed that Amazon is highly well-structured portal, therefore user were
not expecting such output.
WAP designer should put all their skills into action to make the interface user friendly.
In CNN, task-8 when users attempt to find “Score” of any sports such as ice-hockey,
soccer, volleyball etc. if user made any spelling mistake or keyword mistake in “Search
Box” system produce any result. In addition, system does not any effort to produce an
“Alternative”, (i.e. Did you mean: Ice Hockey) such response could significantly
improve user experience between user and the system.
One of major principal of interface design is to enrich the “user experience”, so the
ultimate user must see the system as useful and functional. If a system is useful and
functional, it could result as “customer revisits”. Therefore all major hindrances need to
address and system should be error free. For example, CNN portal contains high
graphics and images, which took longer time to down load pages, especially CNN home
page contains heavy image. In task 2, the link CNN.com/LAW there was almost 9
different big or small images found which noticeably reduce the down loading time.
In the same way, the designers of WAP services should make sure that when an error
does occur, the user is presented with a meaningful and helpful message. In CNN.com
none of videos were operational and while clicking on any video, it does not execute
and system even could not generate any error massage to guide the user about the
possible failure reason. The system was just “Quiet” and the situation was really
annoying. If such these issues could be solved in advance, the user...
