What is an interface?

Apps, Web browsers, e-mail clients, productivity applications
You don’t necessarily need a computer or a screen
Microwave, Fridge, Chair
List the things that can contribute to bad design
- Working in groups - The team might make the mistake
- Constraints (being rushed
- When you are not the typical user
- Your own biases
- Thinking “It’s just common sense…“Beware the Dunning-Kruger effect
- People with zero training are much more confident than they should be (the less you know, the more you think you know about something or the more you know, the more you know you don’t know)
What are the core components of this course?
- To get hands-on experience with multiple design methods: involcing users, prototyping, testing
- How to design, build and evaluate
What are the main components of Design

What are the components of Build?

What are the components of Evaluate?

What is the difference between an interface and interaction?

Draw the Interactive Cycle

In the Interactive Cycle, what constitutes the interface?

In the Interactive Cycle, what constitutes the interaction?

What are the 5 steps of the Interactive Cycle?

In the Interactive Cycle, both the user and the system are required to make several translations, what are they?
From the user’s intention to system input language
From the input language to core system language
From cor system language to output channel
From output channel to user’s interpretation of output
What is the Gulf of Execution?

What is the Gulf of Evaluation?

In general, how does the interface impact the user’s task?

In the history of Interaction Paradigms, what are the paradigms? And who are the visionaries?

What are Batch Interfaces, when were they used and why?

What are Conversational Interfaces or Command-Line Interfaces, what was the years they were popular?

In Conversational Interfaces, who are the users, what are the advantages and disadvantages?

What are Ubiquitous Computing Approaches?

What are examples of Ubiquitous Computing’s range of input and output devices?

What is the ultimate goal of Ubiquitous computing?

Why is design hard?

What is the designer’s fallacy?

what are the core design skills?

What is the definition of a usability goal?
Usability goal addresses the issue of meeting a specific usability criteria
What is the definition of user experience goal?
A user experience goal is concerned with the quality of the user’s experience with the system.
What is the definition of usability criteria?
Usability criteria: something that can be measured to determine if the goal is being met
What are the most common usability goals?
- Effectiveness
- Is the system going what it is supposed to do?
- Efficiency
- Is the user saving time/being productive with the system
- Safety
- does it prevent users from making/recoving from serious errors? does it jeopardize the well-being of the user or otheres?
- Utility
- does it provide suifficient functionality for users to carry out tasks as naturally as possible
- Learnability
- can primary (core) and secondary tasks be learned quickly and easily
- Memorability
- will users remember all the steps to carrying out a task?
What are some User Experience Goals?



The following are potential criteria for the usability goals of a cinema ticket dispenser:
The following are potential criteria for the usability goals of a cinema ticket dispenser:
Learnability: can a user of the cinema’s automated ticket dispenser learn to use the system for the first time in less than 2-3 minutes?
Memorability: if a user has not used the dispenser in months, will he/she be able to use it properly again?
Efficiency: will the user be able to select, purchase and get a ticket in less than a couple of minutes?
Note: when you select a criteria for a particular goal, it has to be measurable or provide specific answers.
In review what are usability goals?
