The fact that the tools respect the spatial arrangement of the elements on the screen contributes to the users understanding of the concepts of graphic interfaces. The users adopt two attitudes with respect to learning new notions. The first is based on understanding what is happening on the screen and the second is based on memorizing procedures. Partially sighted users need to know what is going on and maximize the use of their residual vision while working. Those without vision tend to memorize procedures.
Most blind users prefer the keyboard commands because they increase their productivity.
On the other hand, the mouse is more important for partially sighted individuals. Direct manipulation or, in other words, the use of the mouse is associated with a knowledge of the space on the screen and the elements displayed there. The users greatly appreciated the use of sounds associated with the graphic elements as a complement to the use of the mouse and the keyboard commands. The results confirm the need to conduct tests involving users in the design of access and training programs such as those developed for this project. The use of direct manipulation, combined with audio feedback and an adapted mouse, contributes significantly to the conceptualization of the elements which make up graphic interfaces.
