2- Interaction Design

Question 1

What are some usability goals?

Answer 1

• Efficiency
• Safety
• Utility
• Learnability
• Memorability

Question 2

Who is involved in interaction design? Why?

Answer 2

Multidisciplinary teams (engineers, designers, psychologists, sociologists, artists, product managers…) Because we need a good understanding of users’ emotions, perceptions and communication to effectively develop technology and business to manufacture and market.

Question 3

What are the advantages and disadvantages of having that type of team?

Answer 3

Adv:
- More ideas and designs generated.
- More creative and original designs.
Dis:
- Difficult to communicate and progress with the designs being generated.
- Different languages, and values, can lead to confusion and communication breakdown.
- Complex and expensive.

Question 4

Map all the confusing abbreviations 😅:
- Designing overall user experience.
- Organizing information logically.
- Considering the granular design of the user interface.
- Determining the interaction between a system and its user.

Answer 4

• Designing overall user experience -> UX
• Organizing information logically -> IA
• Considering the granular design of the user interface -> UI
• Determining the interaction between a system and its user -> IxD

Question 5

What is User Experience and how can we design a user experience?

Answer 5

User experience is how a product behaves and how its used by people in the real world. We cannot design a user experience, we can only design for a user experience.

Question 6

Consider a new mechanical keyboard that is smaller than your keyboard (no Numpad). What would be the usability and user experience questions?

Answer 6

Useful: Am i able to complete necessary tasks on the computer (write emails, coding, etc?)
Efficient: Am i able to send my commands to the computer with the smallest delay possible?

Question 7

Continuing with keyboard example, what would be a micro-interaction supported by it?

(Microinteractions are small moments where the user and design interact)

Answer 7

Once a key is pressed by the user, there are lights that appear on the key. Other keys can also be designed to give some sort of feedback to the user when pressed. Some key switch
types include tactile, linear and clicky which all give different levels of feedback and sound to the user.

Question 8

What are the 7 factors that affect ux?

Answer 8

1- Useful
2- Credible
3- Valuable
4- Desirable
5- Accessible
6- Usable
7- Findable

Question 9

When we talk about usability, does that mean ease of use?

Answer 9

Yes, but its more than just ease of use. Need to ensure that designs are efficient, effective, easy to learn and error-tolerant. Usually, usability as ease of use is the priority.

Question 10

When thinking of design principles, where do they come from? give example for feedback, constraints and consistency.

Answer 10

Design principles are generalizable abstractions for thinking about different aspects of designs. They come from a mix of theory-based knowledge, experience, and common-sense.

Feedback: Sending information back to the user about what was been done, what is happening now. It needs to be immediate and synchronized with user actions. Like a loading bar for sending an email and a sound when its sent.
Constraints: Restricting possible actions to prevent errors. Like greying out certain options in a dropdown menu.
Consistency: Designing interfaces to use similar elements and operations if they’re doing similar tasks so theyre usable and easily learnable. Like google docs vs word.
