HCI

1. Consistency of sign posting and pop-up information

   • Every ‘Next’ should be in the same place using the same icon. Navigation around the program should be clear consistent and easy to follow. – intuitive, learn faster

2. On screen help

   • Rather than wasting time looking in manuals, important if no outside help available when working. / Tool tips telling the user what to do. / interactive user manual that answers general

3. Layout appropriate to task

   • There should be standard ‘feel’ to software. e.g. Large/minimal text for a child to minimise reading which builds up user confidence./ Bright colour scheme to attract a young child’s attention. Doing a repetitive task such as entering holiday bookings means you have less guidance on the screen

4. Differentiation between user expertise

   • If the users is an expert then he would chose to use commands to do things quickly and efficiently. if the user is a novice then he use like to support to do simple tasks

5. Clear navigational structure

   • It speeds things up if there is a similar route through the programs (if it is clear) as users do not have to keep learning things / Helps users learn their way around the system.

6. use by disable people

   • If a person is blind then the computer could recognise voice input / Braille keyboard. CONDONE: Font size –(but not as a factor) readability, appropriate to level of user, avoid eye strain
