Q

What is IxD concerned with?

A

The specific interactions that occur when using that software. Things like page transitions and buttons, touch-interactions, keyboard and mouse input, etc. all fall under the umbrella of interaction design.

IxD, on the other hand, refers only to choreographing animations and interactions, making sure they’re pleasurable and quick, and ensuring that the user understands the consequences of their every action.

Q

What is Learnability?

A

Refers to how easy it is for users to accomplish their goals the very first time they interact with the product/service.

Apps or websites that feel familiar because they’re easy to get around are “Learnable”

Q

What is Efficiency?

A

Refers to the speed at which a user can accomplish their goals after they’re familiar with an app or website.
In other words, after you’ve used an app once or twice, how fast can you navigate it?

Q

What is Memorability?

A

When you come to software, after not using it for some time, is it easy for the user to use it? It refers to how easy it is for users to remember how to use the software after not doing so for some time.

Have you ever gone through a period of time without using one of your favorite apps? Once you come back to it, is it still easy for you to use? Or, do you have to spend time re-learning its interface? This is memorability, or how easy it is for users to remember how to use an app or website after not doing so for some time.

Q

What are Errors?

A

How likely are users to make an error, and how many do they make? After making them, is it easy for them to get back on track? This deals with user errors, when they happen, why, and how to help users get around them.

Q

What is Satisfaction?

A

This refers to how enjoyable it is to use an app or website. Is it gratifying and fun? Or, do users feel miserable using it?

Q

What is a “Heuristic”?

A

They offer guidelines that can be applied and tweaked based on a given scenario

Heuristics allow us to standardize common methods we consider to be the “right way” of doing things. The reason usability relies on heuristics rather than rules is because design is art, and art doesn’t always conform to rules. For example, red is typically a color reserved for negative actions and warnings, but take a look at Yelp or Pinterest and you’ll see that all primary actions on their site use the color red.

Q

Visibility of System Status

A

The system should always keep users informed about what’s going on through appropriate feedback within a reasonable period of time.

Q

Match Between System & the Real World

A

The system should speak the users’ language with words, phrases, and concepts familiar to the user rather than system-oriented terms. Follow real-world conventions, displaying information in a natural, logical order.

17
Q

User Control & Freedom

A

Users often choose system functions by mistake and will need a clearly marked “emergency exit” to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.

18
Q

Consistency & Standards

A

Users shouldn’t have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions.

19
Q

Error Prevention

A

Even better than a good error message is a careful design that prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.

20
Q

Recognition Rather than Recall

A

Minimize the user’s memory load by making objects, actions, and options visible. The user shouldn’t have to remember information from one part of the dialog to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate.

21
Q

Flexibility & Efficiency of Use

A

Accelerators—unseen by the novice user—can often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.

22
Q

Aesthetic & Minimalist Design

A

Dialogs shouldn’t contain irrelevant or rarely needed information. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.

23
Q

Help Users Recognize, Diagnose, & Recover from Errors

A

Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.

24
Q

Help & Documentation

A

Ideally, a system could be used without documentation, but it’s still sometimes necessary to provide it for your users. Any such information should be easy to search, focused on the user’s task, list concrete steps to be carried out, and not be too large

25
Q

What is a heuristic evaluation?

A

A method used to uncover usability issues in a user interface so that they can be iterated and improved upon

26
Q

When performing a heuristic evaluation, ensure your evaluators…

a. Don’t share their results with other evaluators until the test is concluded
b. Share their results with other evaluators before and during the test.

A

a. Don’t share their results with other evaluators until the test is concluded

27

c. Contextual requirements
d. Keyboard and mouse input

28
Q

You’re working on a new character mesh for your up-and-coming indie game, “Duck Simulator: A Fine-Feathered Adventure.” Just when you’re about to finish, you accidentally click the “X” button to close the program; however, a pop-up dialog box asks you if you really want to quit without saving, allowing you to click “no” and save your work. This is an example of what usability heuristic in play?

a. Consistency and Standards
b. Recovery from Errors
c. Help and Documentation
d. Error Prevention

A

d. Error Prevention

29

Why is usability important for a site or app?

a. Users will be able to navigate the site or app smoothly and accomplish their goals without trouble
b. Users will intuitively know how to use a site or app and not have to refer to onboarding instructions

A

a. Users will be able to navigate the site or app smoothly and accomplish their goals without trouble
