Compose a 2000 words essay on Qualitative Interface Evaluation. Needs to be plagiarism free!
Since this task is important in software development, experts have agreed on eight most basic characters of a good user interface. While evaluating the interfaces in this paper it will be important to look at these characteristics because they will be the basis of over evaluation. The techniques for interface evaluation among other parameters will be looking at these characteristics. They include: 1. Clear The main aim of any interface to enable users access information and complete their tasks with a lot of ease. Have a clear interface where icons and the menus are well placed and have a clear meaning is important for a successful interface. Users should not be frustrated by the symbols or icons on the interface, one should provide a pop-up message with details of the function of that interface this makes it more clear. While pointing at that icon you may not know the function of it but a pop up message appears which explains the function. 2. Concise This means straight to the point users do not want a lot of details in the interface. While making the interface clear one should not be trapped into adding a lot of information to overload the interface. The icons or details should be short to the point. The volume icon has a scale and icons which shows the high and low volume level. Although it is not easy to keep things, clear and concise developers should strive to achieve this.

While developers strive for uniqueness in their interface one thing should be clear, the interface should be familiar to the users for them to have interest to learn and use them effectively. Naturally, users do not like new things, different environment which they will struggle to adapt. Things that are familiar or terms which one uses should be familiar to the users of the system. A system that uses icons should be keen on the type of the icons they use because the context of the system is very important. The screen shot below shows the user that he/she does not need to learn more about the interface because these are the tasks that they want to accomplish using this application hence easy to use.

It is frustrating for users to wait longer as their requests are being loaded slowly. The user should also have feedback from the system such as the percentage of work done by the system, remaining time and completion status either failed or successful. When the program is loading for instance, a progressing bar or a spinning wheel indicates the task status. The program below shows the time elapsed, time remaining and the percentage of the task done. 5. Consistent Users will learn and advance well in their interface usage if the design system is consistent. Having a system with different interfaces for each version of the program disorients the users. The placement of the Icons, tabs and other items on the interface must be consistent. For instance Microsoft interface are consistent for its application package which enables users to easily adapt from one application to another. 6.
