Human Factors and User Interfaces Assignment

The usage of indistinguishable icons for different functions leads to users’ confusion. In Samsung Galaxy S1, it is difficult to differentiate because the icons are duplicative and hardly to be distinguished by the users. For example in S1, the email icons and message icons are very similar which confuses the user. This problem violates heuristic #5 which states that vocabulary, labeling, and functionality should be consistent within specific tasks and across the interface as a whole.

Whereas, in iPhone, it minimize the use of repeated icons and the icons are made in considerations for the users. It is suggested that Samsung can replace repeated icons with highly intuitive icons. For those applications which have long names, just simply rename to a simpler one so that it can be eased with a better recognition. This problem area is ranked as a major usability problem because it occurs in various places throughout the interface and also because it cannot be solved by any specific action on the part of the user.

In addition, users may simply become confused by this variant terminology. If the menu bar and the contextual right-click menus are not consistent in the options offered, users may be fooled into believing that a specific task cannot be performed. 2.

Besides, the poor color arrangement of rectangular frames on the home screen that form the backgrounds for icons. This leads the user difficult to read the texts/icons/photos. For example, in S1, there are many unrelated functions have similar background color failing to provide uniformity and often causing as to even their functions. This dazzled the users. On the contrary, iPhone provides ease of use to users by applications background only when necessary and using icons that intuitively represent their functions.

Thus, the user will not be dazzled by the complicated home screen. For the apps, let take Facebook as an example. The size of the posted item is small relative to the poster’s image. Thus, it is difficult for the user have a glance at the photos. If the photo is posted next to the video, it is also hard to distinguish the images and videos as they have the similar size. In contrast, in iPhone, the relative sizes of the posted items are large and clear enough for the users to see.

In S1, there is a problem that the indicator showing users’ call status is unclear. It is difficult for users to recognized you are in the call as the in-call status only get displayed on the top of the screen which is small and hard to see. Whereas, iPhone is easy to recognize no matter you are running an application during call. It is suggested that the color of bordering rectangular frames according to a consistent pattern for a uniform feel and enlarge the photos’ size so as to show clearer which is easier for users to read.

Also, the in-call status icon should be larger to show the users they are in the call. This problem area is ranked as a major usability problem because it occurs in various places throughout the interface and also because it cannot be solved by any specific action on the part of the user. In addition, users may simply become confused by this variant terminology. If the user is dazzled by the user interface, their incentive to use will be greatly reduced.
