Usability is a quality attribute that assesses how easy user interfaces are to use. The word "usability" also refers to methods for improving ease-of-use during the

design process.

!

Jakob Nielsen, 2003.

Usability is defined by 5 quality components: !

Learnability: How easy is it for users to accomplish basic tasks the first time they encounter the design?

Efficiency: Once users have learned the design, how quickly can they perform tasks?

Memorability: When users return to the design after a period of not using it, how easily can they reestablish proficiency?

Errors: How many errors do users make, how severe are these errors, and how easily can they recover from the errors?

Satisfaction: How pleasant is it to use the design?

A key one is utility, which refers to the design's

functionality: Does it do what users need?

What are we going to do?

We will have fun with HCD process. We will

try to DESIGN Melbourne CBD

GROUND based on pedestrians experience!

Task 1 Mapping the campus: Each pair of students should explore and design routes in The University of Melbourne based on provided start and end points and based on their own experiences and needs.

RESEARCH Phase

Research comprises "creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of man, culture and society, and the use of this stock of knowledge to devise new applications."(Wikipedia)

Quantitative research Designed to generate accurate and reliable measures that

allow statistical analysis Appropriate to measure both opinions, attitudes, behaviors

and preferences Ex: elections: quantify the preference of the electorate

Qualitative research Has no statistical basis Analyzes profoundly non-measurable data - feelings,

sensations, perceptions, thoughts, intentions, past behavior, understanding reasons, meanings and motivations - from a certain group of individuals in relation to a specific problem.

Involves the development and refinement of new ideas. Extract reasoning, new discoveries, ideas and interpretations

Qualitative vs Quantitative

Qualitative vs Quantitative

!!Example: Election

Theory: Based on the history of elections in Melbourne

Hypothesis: If Elena's President popularity in Melbourne is large, then the chance of the mayors with the same political side be elected is great

Public Target: the voting population in various parts of the city

Data collection: objective questions "Which candidate Mr/Miss vote for?"

!Fragmentation of complex relationships in different variables allow the researcher to isolate and test other effects.

And if leaving Elenas politics side, who wins?

Interpretation of the data

Quantitative research

!!

Are generally open

Originate in the context of the researcher

Style and interest also influence

Can describe states or processes

Assumptions can be confirmed or discovered
