How the effectiveness of HCIs may be measured Quantitative measures of effectiveness Speed The speed at which an interface interacts with the user is fundamental to its effectiveness. If it reacts very slowly to a user then it is likely to be ineffective. Speed can be measured as: • How quickly the user can input a command • The speed at which a user can type in any data • The speed of throughput‚ or the response given by the interface • The length of time necessary for the user to comprehend

study of Human-Computer Interaction (HCI) finally took center stage in the mid-1990s as the World Wide Web‚ e-mail‚ and Windows 95 burst upon the scene. Over the years‚ computers and programs have become easier to use. Computer programs have become more user friendly‚ taking advantage of “point and click” design. Minimal mouse clicks are only part of the picture to improve the computing experience. Cleaner‚ less cluttered “work spaces” for software are the heart of HCI. Users can focus on the tasks at

Poverty is measured in various ways based on the different cultures‚ lifestyles‚ experiences‚ and government standards. In countries such as America‚ the government has set up a poverty line that defines absolute poverty standards‚ or the income needed to provide for basic needs of the family. Government standards are an accurate way to compare families labeled as being “poverty stricken” because the line of poverty takes into account the income needed to cover basic needs for the variety of families

THE IMPACT OF HCI ON SOCIETY‚ THE ECONOMY AND CULTURE What does HCI mean? HCI stands for Human Computer Interaction‚ one of the main focuses within HCI is the way humans’ use computers. Studies and research are undertaken to explore how people use and interact with computers and how new designs would affect users future interaction. Also when creating a GUI you need to follow the Schneidermans Principles there are 8 altogether which are: 1. Strive for consistency. 2. Enable frequent users to use

Measuring the effectiveness of human computer interaction - HCI - can be complex as it involves many influencing factors‚ some of which are determined on an emotional level (making it subjective rather than quantitative). The effectiveness of HCI relates to the usability of a computer system by a human. For a computer to be effective‚ HCI levels must be high. In simple terms‚ a computer that is difficult to use is not a good computer. Indicators of the effectiveness of HCI There are a
