ÿ Interface design involves creating a user interface (UI) for a digital device.
ÿ Interface design prioritises usability, communication, personalisation, and functionality.
ÿ There are various types of user interfaces, each suited to different types of interactions, products, and
user needs.
ÿ Product Interfaces can be simple, complex, static and dynamic. Understanding each interface’s
characteristics enables designers to create interfaces that are appropriate for the product’s purpose and
the user’s requirements.
ÿ User-centred design (UCD) focuses on making products that truly meet users’ needs, providing value
at every step of the design process.
ÿ To bring user-centred design principles into the product creation process, designers often develop user
personas and storyboards that capture and represent the target audience’s needs, behaviours, and goals.
ÿ User Personas are fictional profiles created to represent different types of users who may interact with
the product.

ÿ A storyboard captures the flow of the user experience, showing key steps and moments of interaction
to provide insight into the user’s perspective.
ÿ In combination, user personas and storyboarding bring the user’s voice into the design process, ensuring
that every feature and interaction is meaningful, targeted, and aligned with real-world needs.
ÿ Effective user interface (UI) design is founded on principles that ensure the interface is functional,
usable, and enjoyable. By following these principles, designers may create intuitive interfaces that assist
users in achieving their goals.
ÿ User experience (UX) involves designing products to offer seamless, enjoyable, and meaningful
interactions.
ÿ To deliver a strong user experience, designers focus on three core aspects – usability, accessibility and
pleasure.
ÿ Interaction Design (IxD) deals with establishing a communication channel between the user and the
product, service, or system.

ÿ Ergonomics is the science of designing products, systems, and environments to meet human needs,
enhancing comfort, safety, and productivity.
ÿ Ergonomic design addresses both physical and cognitive factors, making products intuitive and
comfortable to use.
