Question 1.1
How can you ensure that software products are designed to provide a good user experience?
As an interaction designer, you can ensure that software products are designed to provide a good
user experience by following these practices:
1. User-Centered Design (UCD): Involve users throughout the design process, from initial
research to testing prototypes, ensuring the product meets their needs and preferences.
, 2. Adherence to Design Principles and Guidelines: Follow established interaction design
principles, such as consistency, feedback, and simplicity, and adhere to guidelines like the
Nielsen Norman Group's heuristics or Apple's Human Interface Guidelines.
Question 1.2
Discuss the design principles that guide interaction design.
Design principles are fundamental to creating interactions that are both effective and usable. Key
design principles include:
1. Consistency: Ensure uniformity in actions, terminology, and appearance across the interface.
This helps users learn and predict outcomes, improving their overall experience.
2. Visibility: Keep all necessary options and information for a task visible without overwhelming
the user. This principle aids in preventing confusion and helps users understand what actions
are possible at any given time.
3. Feedback: Provide clear, immediate feedback for users' actions, helping them understand the
effect of their interactions. This reduces uncertainty and allows users to adjust their behavior if
necessary.
4. Affordance: Design elements should visually suggest their functionality. For example, buttons
should look clickable, helping users intuitively understand how to interact with them.
5. Error Prevention and Recovery: Minimize the potential for user errors by designing
interfaces that prevent mistakes. When errors do occur, provide easy and intuitive ways to
recover, such as undo functions or clear error messages with guidance.
Question 1.3
Identify and discuss five usability goals. Provide one positive or negative comment regarding
the usability of myUnisa for each goal.
