What is Interaction Design?
Interaction design is about designing interactive products to support the way people communicate and interact in their everyday and working lives.
What is the difference between Good and Poor design?
Good design is:
* user-centered
* easy to learn
* enjoyable
While poor design often leads to frustration due to complexity and inefficiency.
What is usability?
Usability refers to how easy and effective an interactive product or technology is for its users, covering aspects like:
- ease of learning
- efficiency
- maximizing satisfaction and effectiveness
- minimizing errors
What are Usability goals and User Experience Goals?
Usability goals focus on making products efficient and easy to use.
While user experience (UX) goals emphasise creating enjoyable and meaningful interactions.
What is People-Centered Design?
It’s an approach to understand users’ emotional and practical needs. To ensure the product offers pleasure, satisfaction, and effective interaction.
Why is Accessibility and Inclusiveness important in UX and HCI?
- Accessibility ensures that products are usable by people with various abilities
- Inclusiveness makes sure no group is excluded from using the product.
What is the purpose of prototyping in Interaction Design?
Prototyping allows designers to:
- test and refine ideas
- gather feedback from users to improve usability and UX before final production.
What are the key components of interaction design?
Core concepts:
- User interaction
- Design
- Usability
The Focus of interaction design is creating seamless, useful, intuitive and great experiences for the users.
- Not just that they work, but that they also feel good to use
Why is design within HCI user-centered?
By understanding user’s needs, the products can be better
What is the core of interaction design?
Designing for user interaction with technologies
What characterizes a contextual inquiry?
A situational interview and observation
What is a persona and how is it used in HCI?
A generalized description of a typical end-user
What is ethnography?
A method for studying people and interaction in real-life situations
What is wireframes?
A sketching technique
What is a script?
A file with a set of commands for a computer
What is tangible user interface?
A surface/object that the user can manipulate directly
Why is validity of a scientific method important?
It means that the method is scientifically appropriate for investigating the type of problem
What is INTERACTION in the context of HCI?
Interaction between humans and technology
What is Design in the context of HCI?
Form and behaviour of an artefact
What is a USER in the context of HCI?
Anyone who is (directly) affected by the design, aka. Interacting with the design
What is the overall focus of Interaction, Design and User within the context of HCI?
It’s in the context which technology is used in relation to functionality and design
Why can’t designers decide what’s good design? And what should one do to be able to design good?
It has to be user-centered, focused on starting from the users’ needs.
What needs to be done is:
- Do user studies
- Talk to members of said communities/fields
- Etc
- Ask, observe
- Get the facts (i.e. old people aren’t bad at tech(?) lol)
What is the nature of interaction?
The understanding of interaction that we’ve built up.
Examples:
- A smartwatch you interact by wearing it, gestures, voice, touch.
- Chat vs email
- With Chat you expect an immediate response(I think this is changing nowadays)
- Netflix
- Did you choose the movie you decided to watch, or did the algorithm choose it?
How to interact with a digital system? And how does a digital system interact back? Give few examples:
- RFID
- Sensors
- Touch screen
- Keyboard/Mouse
How digital system interact back
- Content on screen
- Audio
- Printer
- Vibration
