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.
