A blinking or flashing item on screen is highly effective for drawing attention. The most effective blinking rate is approximately 2 or 3 blinks per second. Pop-up windows can help focus attention and improve accuracy of control and learning.
Graphical control interfaces Graphical elements can be a helpful in operation of computer programs.
In developing a graphical control interface, consistency is a key element. The visual layout, navigation uses, and graphic display of elements must be the same from screen to screen. One suggested strategy is to define grid areas on the screen and group content information, graphics, and icon buttons in a uniform manner throughout the applications. It should be noted that, despite the common belief that a graphic interface is more user-friendly, the inclusion of a graphic interface does not decrease computer anxiety in novice users. Summary Current research allows construction of these basic guidelines for the presentation of information to users in CBT programs, and for providing cues to guide the users effectively through the lesson.
