      • The user interface (or Human Machine Interface ) is the aggregate of means by which people ( the users ) interact with a particular machine, device, computer program or other complex tool ( the system ). The user interface provides means of:
      • Input, allowing the users to manipulate a system
      • Output, allowing the system to produce the effects of the users' manipulation.
      • (Wikipedia)
      Graphical User Interface (GUI) A visual way of interacting with a computer using items such as windows and icons. (Norman, D., :2004).
    • Active communication
    • A system in human minds that process all the information that they faced through their engaging to earn knowledge. (Hasler, Kersten, & Sweller, :2007). “ A term that refers to the load on working memory during instruction”. (Wikipedia)
    •  
      • Eliminate the unnecessary loads.
      • Reduce the size of the cognitive load by dividing the inter face to smaller pieces.
      • Make instructions to help the interface users to understand what they need to do and how the interface will help them.
      • Do not confuse the users by less ordering the interface content.
      • Allow to the users to use the interface based on their needs and able to control its features based on their readiness.
    • 1- Communicate with interface user by designing the interface contents that are clear and able to lead the user to the accurate actions.
    • 2- Avoid butting the user in confusion situations , by increasing the cognitive load through the disordering in the interface
    • 3- Do not fall in the same mistake that I made in the last slide. Misaligned between the text and the picture increased the cognitive load and make bad effect on the memory process.
    • 4- Take your time in designing a user friendly interface, this will help the users to be more active and will motivate them to improve their interactions with the interface.
