Human/Computer Interface

Syllabus requires you to:

• Recall different approaches to the problem of communication with ICT systems and discuss the resource implications of sophisticated HCI.
• Discuss the implications for customising software to develop a specialist HCI.

Introduction:

Exercise 1:

Designing web-based interfaces for people with disabilities:

• Partially sighted or Poor vision
  • Go to this simulation to find out what it is like to view web pages if you have poor sight
    • Complete all the exercises
• Learning difficulties
  • Look at this simulation that mimics the effects of cognitive disabilities
    • Complete all the exercises
• Blind or partially sighted
  • This simulation uses a screen reader to read out the content of a typical web page for people who cannot view it or who find it difficult to see
    • (Large 2.42 MB file, due to extensive audio content - may take several minutes to download)
• Colour blindness
  • Examples of how an image may appear to people with different types of colour blindness

   

• Many of the design issues of using a web page are simular to issues surrounding the design of a Graphical User Interface

Exercise 2: GUI Styles

• On common industrial standard for PCs is the Windows Style Guide
  • This sets out where different screen elements should appear
  • Means that Windows products have a standard look and feel
    • Helps the user to move from one package to another
  • Example of typical screen layouts (scroll down the page)
• Are there any problems with this approach?
  • Read this article HCI Standards: A Mixed Blessing by Elizabeth Buie

• Test your understanding

• Past Exam Questions

Exercise:

• Do the exercise and questions at the end of Chapter 61 of the textbook.
