ITC203 Wk 5 Designing the User Interface

· Making sure the that things you can do at this time are visible to you, no need to remember or guess at the next steps supports the design characteristic of?

Visibility

Feedback provides the user with a sense of confirmation and the feeling that...

a system is responsive and functioning correctly.

Feedback is about the system acknowledging what...

action has been done and what has been accomplished, allowing the person to continue with the activity. ie: checking a radio button or a check box

The user experience (UX) is a broad concept that applies to...

all aspects of aperson's interaction with a product or service.

Users not only expect consistency across the various screens of an application, but now...

also anticipate consistency across applications.

To make computers easier to use and learn, designers of early visually oriented interfaces adopted metaphors, which are...

analogies between features of the user interface and aspects of the real world that users are familiar with.

Designing the user interface has characteristics of both...

analysis activities and design activities and requires heavy user involvement.

Executive reports are reports that...

are used by high level managers to assess overall organizational health and performance.

Application continuity maintains a...

certain level of consistency over time across multiple releases.

Scenarios are step-by-step...

descriptions of a user's actions.

The user interface (UI) is the set of inputs and outputs that...

directly involve an application user. The part of the system they see and interact with, to them it is the system.

Active discovery is a user-interface feature that leads users into...

discovering hidden features through the use of popup dialog windows, hover effects, and indicators the show there are more features and functions available.

Breadcrumbs (navigation) is the technique of...

displaying the sequence of pages traversed to the current page.

The System Sequence diagram defines input messages, which indicates what...

elements are required to be represented on the user interface screens.

When considering user interface design you must consider the...

entire user experience—what devices are being used and what the users are doing on those devices.

The horizontal approach has many menu items at the top level and...

fewer levels of submenus.

A good user-interface design anticipates common errors and...

helps the user to avoid them or correct them immediately when they occur.

The user interface can be organized in a...

hierarchical vertical or flat horizontal form.

Affordance is a term used to refer to an attribute of an object that allows people to know...

how to use it.

Using a system sequence diagram is a good starting point to...

identify the various screens and forms that may be needed for the user interface for a particular use case.

Mapping refers to the relationship between controls and their effects...

in the real world.

The design principle of closure says that...

interaction via the user interface should have a clearly defined beginning and ending.

A System Sequence diagram shows the system as a black box but show the...

interactions between the user and the system.

The more visible functions are, the more likely users will be able to...

know what to do next.

Usability refers to how easy a system is to...

learn and use. Need to be aware that this means different things to different people as they have different preferences and skills.

Menus are needed to present the user with a...

number of choices per screen group related functions together so users can locate them and to properly sequence related forms to handle complex procedures.

Navigation through an application or a Web site depends heavily on the...

organization of the user interface.

Storyboarding is the process of determining what the user interface needs to provide as we...

progress through a use case and move from screen to screen.

Dialog metaphor - user and computer accomplish task (install program) by...

prompting each other.

Exception reports are reports that...

provide details or summary information about transactions or operating results that fall outside a predefined normal range of values.

Scenarios can be used as a tool in....

requirements gathering, interface design and interface evaluation.

The vertical approach has fewer menu items at the top level, but...

requires multiple levels of submenus.

Feedback is some visual or audio response by the system in...

response to some user action.

Constraints deal with ways of...

restricting the kind of user interaction that can take place at a given moment.

If users use the system all day, it is important to make the interface fast and flexible, with...

shortcuts hot keys voice commands information-intensive screens

Consistency refers to designing interfaces to have...

similar operations and use similar elements for achieving similar tasks.

Detailed reports are reports that contain...

specific information on business transactions.

Affordance means that the appearance of a specific control...

suggests its function.

Summary reports are reports that...

summarize detail or recap periodic activity.

Given that a use case consists of a series of interactions between the user and the system, each interaction is defined as a...

system operation.

As a design activity, user-interface design utilizes other analysis models as input, such as the...

system sequence diagram and use case description

A use case is a selection of scenarios united by...

the same end goal.

State machine diagrams are useful for designing user interfaces to understand what the system should do after the generation of an event and what state...

the system should be in after a particular action.

Part of the user-interface design process is to decide how to design the screens for...

the use case data flows, are individual screens required or can they be combined?

Human-interface objects (HIOs) are those objects that appear on a screen that...

the user can manipulate.

To the user the interface is the system, usability is not what we think is important it is what...

the user thinks is important.

The user interface is a major element in the...

total user experience.

Discoverability a feature of the user interface that provides clues to help the users...

uncover hidden features.

The dialogue metaphor emphasizes the communication that occurs between a...

user and a computer, conceptualized as a conversation.

A good use case description is a good starting point to begin the...

user interface design (iterative process).

Need to think about what information goes in and what information comes out and then think about a...

user interface which will support these actions.

Visibility means that a control is visible so users know it is available; it also means that the control provides...

visual feedback to indicate that it the action has been received and it is responding to that request.

When you design a report the most important thing is...

what information does the person who is reading this report want from this report.

What are the four quantitative ways that usability can be measured?

· Learnability - time and effort required to achieve a particular level of performance · Throughput - speed with which tasks can be achieved, number of errors · Flexibility - ability to respond to changing tasks and environment · Attitude - how positive an attitude users have

What are four possible options to capture scenarios?

· Textual descriptions - use case description · Storyboard - user interface design · Prototypes · Video mock-ups

What are the three principles that user centred design emphasizes?

■ Focus early and throughout the project on the users and their work. ■ Evaluate all designs to ensure usability. ■ Use iterative development.

What are the four types of output reports provided by an information system?

1. Detailed report 2. Summary report 3. Exception report 4. Executive report

What are the three key considerations that will affect the approach to the design of the user interface?

1. Stand alone application or Web browser based 2. Types of device the application is designed for 3. Operating system in use
