Question 1.1 (2 marks)
How can you ensure that software products are designed to
provide a good user experience?
To ensure that software products are designed to provide a
good user experience, interaction designers can:
1. Adhere to User-Centered Design (UCD) Principles: Engage
in user research to understand users' needs, preferences,
and pain points. Involve users throughout the design
process through usability testing and iterative design to
, ensure the final product meets their expectations and
provides a positive experience.
2. Apply Design Guidelines and Best Practices: Utilize
established design principles such as consistency,
feedback, and simplicity. Implement usability heuristics
and follow established design standards to ensure the
product is intuitive and user-friendly.
Question 1.2 (5 marks)
Discuss the design principles that guide interaction design.
1. Consistency: Ensure uniformity in design elements and
interactions across the product. This helps users build
familiarity and predictability, making the product easier to
use.
2. Feedback: Provide clear and immediate feedback to users
after their actions. This confirms that the system has
received their input and is processing it, helping users
understand the consequences of their actions.
3. Affordance: Design elements should suggest their
function. For instance, a button should look clickable, and
a slider should indicate it can be dragged. Good affordance
reduces the learning curve for users.
4. Visibility: Make important functions and information easily
accessible and visible. Users should not have to hunt for
features or information; it should be readily apparent.
, 5. Error Prevention and Recovery: Design to minimize the
risk of user errors and provide clear guidance for error
recovery. This includes error messages that are informative
and offer solutions or steps to correct the problem.
Question 1.3 (6 marks)
Identify and discuss five usability goals. Also, provide one
positive or one negative comment regarding the usability of
myUnisa that you have experienced for each of the goals.
1. Effectiveness: The degree to which users can complete
tasks successfully.
o Comment: Positive - myUnisa's assignment
submission system is straightforward, making it easy
for students to upload their work correctly.
2. Efficiency: The speed and effort required to complete a
task.
o Comment: Negative - Finding specific course
materials can be slow due to a complex navigation
system, which affects overall efficiency.
3. Satisfaction: How pleasant the user experience is.
o Comment: Negative - The overall design of the
myUnisa interface can feel outdated and less
engaging, which can impact user satisfaction.
4. Learnability: How easy it is for new users to accomplish
tasks the first time they encounter the design.
