Test:     Human Computer Interfaces

All of these questions have appeared on past papers.

1          The Human Computer Interface (HCI) on a computer can be adapted for different tasks.           

            Describe in detail, three factors, other than layout appropriate to task, using different examples 
            that should be taken into account when designing a good HCI. [6]

2          Describe the factors that should be taken into account when designing an appropriate layout of 
            an HCI that would be used by a young child learning how to read. [4]

3          As computer systems have become more complex the interface has become increasingly important. 
            Other than differentiation between user expertise, describe four factors that should be taken into 
            account when designing a good human computer interface and for each factor describe why it is 
            important. [8] 

4          The Human Computer Interface (HCI) is an important part of an ICT system. Describe four factors which 
            should be taken into account when designing a good HCI. Explain why each factor is important. [4×2] 

5          The Human Computer Interface (HCI) is an important part of an ICT system.

             (a)        Examine the different needs of an expert user and a novice user and describe how they can be 
                          met when designing the HCI. [5]

            (b)        Discuss using examples, the features of a HCI that would be suitable for the disabled user. [4]
