week 3 - Human–Computer Interaction — Design Process, Envisionment, and Psychological Principles of Design 1
, Demonstrate an understanding of software application design and factors that
determine the success or failure of interactive applications, and
Design, develop and implement basic/intermediate-level software applications.
UX Design Process:
The Double Diamond Model:
model divides the process into 2 major parts
the vision for the design and adopts a strategic approach which identifies design
problems - it encompasses activities from INTENTION to the DECISION point
- it seeks to discover and define
the execution, tactical nature, aiming to deliver a solution to the problem - from
DECISION to COMPLETION point - seeks to design and deliver
Activities of the user experience design process?
understanding : what the system or service has to do and how it should look like -
involves eliciting the requirements and researching prospective users and other ppl
that could be affected by the proposed system which shall be accomplished in terms
of the PACT framework - may involve participative design, interviews and
questionnaires

, conceptual and physical design : designing a system in the abstract that is
considering what information and functions are needed, thinking of overall purpose.
The physical design makes things concrete and detailing the look and feel of the
product by structuring the interactions into logical sequences
envisionement : making ideas visible to help designers clarify their ideas and let
people evaluate them - many techniques : sketching, storyboards, navigation maps,
wireframing, prototypes
evaluation activity: reviewing and testing the design to check if requirements are
met
⇒ these activities are interrelated with the evaluation being a central part of the design
process so that everything gets evaluated at every step of the process
The envisionment activity and its techniques
make ideas visible in order to represent design work to ourselves and to others
helps designers to see things from other’s persepective
it involves externalizing thoughts by the means of various stories, scenarios, sketches,
presentations, software prototypes..
the Sketching technique :
