In the present invention, it can be detected whether the active floating function key is constantly touched to determine whether it is in an active state.

At step 805, the touch pressure at other locations is detected.

When the other position of the touch screen is detected, when the contact is touched, the sliding track of the contact or the like is detected to determine the target object selected by the user.

Step 806, the selection and other operations are completed.

The target object selected by the user is determined by determining the sliding trajectory of the other contacts.

Specifically, determining, by the contact touch position on the touch screen, the selected target object is: determining an object touched by the contact as the selected target object; or detecting the touch screen A sliding track of the contact, the selected frame is determined by the sliding track, and the object in the selected box is taken as the selected target object. The selected frame is determined by the sliding trajectory, wherein: a rectangular frame determined by using a line connecting the start point and the end point of the sliding track as a diagonal line is a selected frame; or The circular frame determined by the diameter of the starting point and the ending point is the selected frame; or the closed area composed of the sliding track is the selected frame; or, based on the semi-closed area composed of the sliding track The closed area is formed according to the sliding tendency of the contact, and the closed area is the selected frame.

Step 807, releasing the touch pressure at other locations.

By detecting the voltage or resistance change of the contact pressure or the touch position, it is detected that the contact at the other position releases the touch pressure on the touch screen, thereby determining that the current target object is selected and the selected target object is determined.

Step 808, to activate the floating function key.

After the selection of the target object is completed, the touch pressure on the floating function key is released, thereby deactivating the floating function key.

And when the floating function key is activated and is not operated after the set time is exceeded, the activation is deactivated. If the floating function key is activated and then touched by the contact again, it enters a deactivated state; or, when the floating function key is activated and continuously touched by the contact, the deactivated state is entered.

In the present invention, after the touch screen is operated to enter an interface, it is judged that the floating function key is available and activated, and the function of the floating function key is preset, and the user can double click or click again. The mode function is switched to the preset second function state, and the predetermined operation is completed by sliding the second contact after selecting the desired function mode.
