Summary INF1520 ASSIGNMENT 3 2023

Question 1 [10] 1.1 There are, potentially, many mistakes that designers can make when designing interfaces. Explain what is meant by Norman (1999) Hampering of the Natural Evolution of Design, with specific reference to forces that works against evolution design. (6) 1.2 User should avoid clutter especially when designing interfaces. Provide some reasons why it is important to avoid cluttering of interfaces? (4) Question 2 [3] Define the following terms: 2.1 Synchronous and asynchronous systems (2) 2.2 Problems associated with information age. (1) Question 3 [5] What are the five principles that relate flexibility? Question 4 [6] 4.1 Discuss what is meant by the term mapping and provide an example. (2) 4.2 Explain with the aid of an example what natural mapping are normally used for with specific reference to the figure indicated? 4.3 What does the page backward and forward icons provide? Affordance, constraint or natural mapping. (1) 4.4 Does the traffic light depict natural mapping? Yes or no? Explain your answer. (2) Question 5 [6] Differentiate between guideline< standards and principles. Question 6 [6] When designing it is important to identify the correct interface type to use. 6.1 When will web based interfaces be used? (2) 6.2 What are multimodal interfaces used? (2) 6.3 Differentiate between augmented and mixed-reality interfaces? (2) Question 7 [6] 7.1 Indicate how robotic and drone interfaces can be used in a community by providing examples. (3) 7.2 Provide advantages of how multimedia interfaces in the community of health services can be used. (3) Question 8 [8] Evaluation can be done in laboratories or in real-life environments where systems will be used. Identify five evaluation approaches and explain how and where each will be used.
