Human Computer Interaction

1. What is Human Computer Interaction?

• Human-computer interaction (HCI) is a multidisciplinary field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design

1. What is brain storming relating to Human Computer Interaction?

• Brainstorming is a method design teams use to generate ideas to solve clearly defined design problems. In controlled conditions and a free-thinking environment, teams approach a problem by such means as “How Might We” questions.

1. What is Contextual Inquiry?

• Contextual inquiry is a semi-structured interview method to obtain information about the context of use, where users are first asked a set of standard questions and then observed and questioned while they work in their own environments.

1. What is Making sense data?

A practical, step-by-step approach to making sense out of data Making Sense of Data educates readers on the steps and issues that need to be considered in order to successfully complete a data analysis or data mining project.

1. What is dynamic prototype in Human Interaction?

• A prototype is an early sample, model, or release of a product built to test a concept or process or to act as a thing to be replicated or learned from. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is designed to test and try a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea.

1. Discuss the technology and change?

A technological change in economics may be defined as an increase in the efficiency of a product or process that results in an increase in output, without an increase in input. It has three stages: Invention - the creation of a new product or process.

1. Discuss the concepts of interaction design?

• Interaction Design (IxD) is the design of interactive products and services in which a designer's focus goes beyond the item in development to include the way users will interact with it. Thus, close scrutiny of users' needs, limitations and contexts, etc. empowers designers to customize output to suit precise demands.

  Publisher Summary
  This chapter focuses on individual differences in human–computer interaction. Differences among users have not been a major concern of commercial computer interface designers. Even behavioral scientists usually select narrowly defined user samples to minimize experimental error when comparing the mean performance of different systems. Those behavioral studies that have analyzed differences among users often have produced descriptive results rather than prescriptions for interface design. In the future, interface designers should focus a great deal of attention on the differences among potential users for three reasons. First, individual differences usually play a major role in determining whether humans can use a computer to perform a job effectively. Second, personnel selection testing, the standard solution to problems of job-related individual differences, cannot be applied to many settings where humans interact with computers. The third reason for designers to be concerned with individual differences is that the technology has reached the point where it is possible to accommodate more user differences.

1. Discuss Data Gathering and Requirements Analysis with focus in HCI aspects?

• The data gathering methods we choose to use are focus group, questionnaires and natural observation. We choose these methods because they are the most appropriate for our project in terms of validity and knowing the problems of the websites. They are useful means to get information from both users and stakeholders. We use focus group to bring opinions and perspectives into the projects and to highlight disagreements and concerns from both the users and stakeholders. Additionally, we use questionnaires to get information from the users and stakeholders and naturalistic observation to understand the requirements of the company.

The data analysts will gather the data. It will be gathered by going to the company to observe their tasks and operations, getting information from the stakeholders and users via questionnaires and focus groups.

The data will be analyzed by observing the most common requests and answers, say and determine what is needed and the problems of the syste

1. What are Interfaces Design and Prototyping?

• User interface (UI) prototyping is an iterative development technique in which users are actively involved in the mocking-up of the UI for a system. ... A basis from which to explore the usability of your system. A vehicle for you to communicate the possible UI design(s) of your system.
