Switching direction determine selected button be in safety keyboard region up and down in the switching of which direction.Such as,
If as it is shown in figure 5, the button in currently selected is 5, then button switching direction is to determine that terminal switches from 5 to 4, or from 5 to 6
Switching, or switching etc. from 5 to 2.
In the present embodiment, according to choosing operational order to be assured that button switching direction, such as, operational order is chosen
In order to switch to choose the right button of currently selected middle button then to may determine that, button switching direction is for switch to the right.
Step S206, according to the described button currently chosen in described safety keyboard region, and the switching of described button
Direction, target button selected after determining switching.
Concrete, according to button the most selected in safety keyboard region and button switching direction, terminal just may be used
So that selected button is switched to target button by current selected button.Such as, as shown in Figure 6, in currently selected
Button be button 7, if button switching direction is defined as to the right, then terminal may determine that to the right switching after selected target
Button is 8.
Step S207, obtains the content of text of described target button, and calling the text-to-speech engine in terminal system will
The content of text of described target button is converted to speech data.
Concrete grammar is referred to step S102.
