It is more concerned with the design intuitiveness of the product and tested with users who have no prior exposure to it. Despite the differences in usability testing modes and flavors, all generally have the following in common: They use a representative set of users. Thus, HCI is a very crucial concept in the development of system processes because it entails creating and understanding software and other technologies that people use in their day-to-day life.

Usability testing and user testing are slightly different, both are testing techniques in HCI. The existing methods and usability frameworks are designed to for general-purpose usability testing. The purpose is to test the concept and build upon the initial framework (or scrap the idea altogether). Usability is a term that is defined differently depending on which branch of science you are investigating. In order to check the user experience, you need to have a product that you’re going to test. Overview. McGovern G (2003) Usability is good management.

Such testing is paramount to the success of an end product as … This usability inspection method does not rely on users which can be burdensome due to the need for recruiting, scheduling issues, a place to perform the evaluation, and a payment for participant time. Our usability test focused specifically on the search box. Usability testing can be done formally, in a usability lab with video cameras, or informally, with paper mock-ups of an application or Web site. The methods used for usability testing, in decreasing order of frequency were: questionnaires (n = 105), task completion (n = 57), 'Think-Aloud' (n = 45), interviews (n = 37), heuristic testing (n = 18) and focus groups (n = 13). Test participants are chosen randomly. A practical example that comes to mind would be a bar code scanner -- like the type of scanner you might encounter at the checkout counter of a store. Usability testing is a method by which users of a product are asked to perform certain tasks in an effort to measure the product's ease-of-use, task time, and the user's perception of the experience. Usability testing is frequently done by industry and usability experts to discover usability problems in specific UIs. User testing is a more formal process. Human-computer interaction (HCI) and usability are the key aspects for developing computer and mobile systems that enhance system facilities and satisfaction of end users [1] [2][3][4]. 0000001621 00000 n User testing is a more formal process.
