Human Computer Interface

Human Computer Interface

1. When creating a good user interface, there are a number of factors to consider and these include:

   • Consistency of signposting and pop-up information
     • All the aids to navigation such as Next/Previous buttons, pop-up menus, icons etc. all look the same from screen to screen.
   • On-screen help
     • All software packages should have an on-line help facility. Besides providing help should the user need it, the software should recognize and anticipate the user's goals
   • Layout appropriate to task
     • Target audiences - Children = Minimum amount of text, bright colours, uncluttered
       • CAD = Customisable, minimise mouse movement + keep working area as large as possible, design pull down menus so most used option at the top
   • Differentiation in user expertise
     • Novices, experienced + experts.
     • Each will have different needs:
       • Novice = ease of learning + easy access to help
       • Expert = Least possible time taken
   • Clear navigational structure
   • Use by disabled people
