The arrangement position of each element in dummy keyboard is recorded, the arrangement position of each element includes the position of each element
And the relative position of each element.Specifically, the information preservation of record is in specified file, so as to subsequent calling.Its
In, the relative position of each element refers to relative position of each element in dummy keyboard, for example, it is assumed that in dummy keyboard
In, letter " A " and alphabetical " S " are in same a line, and in the left of alphabetical " S ", then the step needs record " letter " A " and letter
" S " is in same a line, and in the left of alphabetical " S " " corresponding information.
Step S12 determines the view field for including finger in the subpoint of screen.
In this step, the shape of view field can be circle, square, rectangle etc., and view field only need to include hand
Refer to the subpoint in screen.
Optionally, when view field is round, the view field for including finger in the subpoint of screen is determined, it is specific to wrap
It includes:
A1, the length and width for comparing individual element in dummy keyboard, to determine the length and individual element of individual element
Width in the larger value.Usually, the length and width of each element is fixed in dummy keyboard, at this moment, is only needed
Compare the length and width of an element in dummy keyboard.
A2, using finger screen subpoint as the center of circle, it is larger in the length of individual element and the width of individual element
The presupposition multiple of value is radius, generates projection circle.Assuming that the length of element is h, width w, it is assumed that w > h, presupposition multiple are greater than
1, and the specified value being less than in [2,3], for example, it is assumed that preset multiple is 2, then projecting round radius is 2w.Make pre-
If multiple is greater than 1, to guarantee that view field covers element suspicious around, and it is specified in [2,3] to be less than presupposition multiple
A value, to prevent the range of view field excessive, to cover too many invalid element.
Step S13 chooses the element of view field.
