process of measurements. When reporting results from a usability test, you should focus primarily on your findings and recommendations that are differentiated by levels of severity. Usability testing using paper prototypes – The Method. The group has orga­ nized a number of international working conferences on interactive software technology, the, Over the past two decades, the HCI community has proposed specific features that software applications should include to overcome some of the most common usability problems. The modelwas implementation oriented and built on an object concept and the notion of interaction as consisting of commands and responses. Data Logging can provide extensive timing data which is generally important in HCI & Usability. The goal is to facilitate the adoption of the design thinking process for software developers. Also Abort Operation enables the user to be more productive. However, existing HCI usability heuristics, Human centricity refers to the active involvement in the overall product lifecycle of different human actors including end-users, stakeholders and providers. In this paper we address web user interface (UI) automatic evaluation and in particular discuss the ontology design for capturing knowledge of web usability domain for UI evaluation. Indeed, several studies showed the importance of usability for the quality of use and adoption of software systems. The form may be divided into “Contact Information” and “Billing Information”, rather than mixing the two and confusing users. The usability testing is a way of assessing the degree to which an interactive system is easy and pleasant to use with a view of identifying usability problems and/or a collection of usability measures/metrics [2, 3]. Indirect observation Select one: a. Using metaphors can be an effective way to communicate an abstract concept or procedure to users, as long as the metaphor is used accurately. After Working Memory, the information may go into Long-Term Memory or simply be forgotten. ABSTRACT: The following research investigates issues relating to the field of Human-Computer Interaction and Usability Engineering. changing the text color could lead to decrease of accessibility for users with low vision or cognitive impairments.
