the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use this concept is. Usability. The interactive. The planning.

develop usable products is a goal of. interaction design. human machine interface. interaction.

it is a type of computer device that interact directly to machine. keyboard. computer. mobile.

the interaction includes hardware and. software. keyboard. mouse.

it is an aspect of user friendliness which prevents the user from worrying about technical details. The interactive systems. The interactive design. computer transparency.

It is concerned with joint performance of tasks by humans and machines. HID. HCI. HIC.

the environment of the activity in PACT analysis which is. technology. context. people.

the first element in PACT analysis is. activity. technology. people.

the tools are used and how might new developments be used? that is. technology. context. people.

Use of the design is easy to understand, regardless of the user's experience, knowledge, language skills, or current concentration level means. Equitable Use. Simple, Intuitive Use. Flexibility in Use.

relevant user characteristics and skills in PACT analysis. Context. technology. people.

it is provided for approach, reach, manipulation, and use, regardless of the user's body size, posture, or mobility. Size and Space for Approach & Use. Low Physical Effort. Tolerance for Error.

this figure presents a PACT Analysis. number.... presents technologies. number.... presents Activities in contexts. number.... presents People. number.... presents opportunities. number.... presents requirements.

goals of interaction design involve users in. design process. input process. output process.

the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use, this concept is. Usability. Learnability. visibility.

it is the accuracy and completeness with which specified users can achieve specified goals in particular environments. Effectiveness. Learnability. visibility.

it is defined as the resources expended in relation to the accuracy and completeness of the goals achieved. Efficiency. Effective. Learnable.

it is the comfort and acceptability of the work system to its users and other people affected by its use. Satisfaction. Effective. Efficiency.

a usability is combined of. 3 elements. 5 elements. 7 elements.

Every designer wants to build high-quality interfaces that are admired by colleagues, celebrated by users and imitated frequently. analyst's Aim. Designer's Aim. programmer's Aim.

Why Usability is hard?. People are unpredictable. People (users) are all different. Design skill isn't enough. Evaluation with users is required. Designer's pride. Safe to use. new ways to think, break out of the box. Effective to use. Efficient to use.

usability has many goals which are. Effective to use. Efficient to use. Safe to use. Have good utility. Easy to learn. People (users) are all different. People are unpredictable. Design skill isn't enough.

mention the Skills of the Interactive Systems Designer. knowing about people. technologies. activities and context. design.

it is a characteristic of PACT analysis characteristics. language. culture. experience and expectation. Safe to use. Efficient to use.
