Problems solved by technology

[0002] In order to solve the problem of misjudgment of finger keys caused by first touching other adjacent keys when pressing keys, the current existing technology adopts the method of enlarging the keys of the virtual keyboard or increasing the distance between the two keys. method, although this can reduce the possibility of touching other adjacent keys when the finger presses the key, but there are too many screens occupied by the virtual keyboard, and when the operator uses the thumb to input the key, it will cause inconvenience due to the large operating range, etc. question

Embodiment 1

[0044] Embodiment 1: When the operator presses the button icon "2" with his finger, the horizontal coordinate of the touch screen point of the corresponding finger is 138, and the vertical coordinate is 48, that is, when the finger presses the button icon "2", the finger first touches the button icon " 5" top right

[0045] If the horizontal coordinate 138 and the vertical coordinate 48 of the touch screen point of the finger are directly matched with the horizontal coordinates and the vertical coordinates of the button icon, then the matching point is in the area of ​​the button icon "5", that is, it is judged to press the button icon "5", does not match the key the operator intended to press,

[0046] According to the technical scheme of the present invention, when judging the finger keys, the longitudinal coordinates of the button icons matched with the longitudinal coordinates of the corresponding finger touch screen points are moved down by 20 points, and the horizontal c...

Embodiment 2

[0047] Embodiment 2: When the operator presses the button icon "4" with his finger, the horizontal coordinate of the touch screen point of the corresponding finger is 35, and the vertical coordinate is 90, that is, when the finger presses the button icon "4", it first touches the button icon " 7" top end

[0048] If the horizontal coordinates 35 and vertical coordinates 90 of the touch screen point of the finger are directly matched with the horizontal coordinates and vertical coordinates of the button icon, then the matched point is in the area of ​​the button icon "7", that is, it is judged to press the button icon "7", does not match the key the operator intended to press,

[0049] According to the technical scheme of the present invention, when judging the finger keys, the longitudinal coordinates of the button icons matched with the longitudinal coordinates of the corresponding finger touch screen points are moved downward by 20 points, then the horizontal coordinates of ...

Embodiment 3

[0063] Embodiment 3: The operator presses the button with the finger of the left hand, and when the finger presses the button icon "2", the horizontal coordinate of the touch screen point of the corresponding finger is 75, and the vertical coordinate is 48, that is, when the finger presses the button icon "2", there is a first touch Go to the upper right end of the button icon "4"

[0064] If the horizontal coordinate 75 and the vertical coordinate 48 of the touch screen point of the finger are directly matched with the horizontal coordinate and the vertical coordinate of the button icon, then the matching point is in the area of ​​the button icon "4", that is, it is judged to press the button icon "4", does not match the key the operator intended to press,

[0065] According to the technical scheme of the present invention, when judging the finger keys, the vertical coordinates and horizontal coordinates of the button icons matched with the vertical coordinates and horizontal...

Abstract

The invention discloses a method for a judging virtual keyboard finger key of a touch screen mobile phone, which comprises the following step of: displaying a virtual keyboard having multiple rows of key icons on a display screen. The method is characterized in that a longitudinal coordinate of a key icon which is matched with a longitudinal coordinate of the corresponding finger touch screen point is set to be moving downwards for certain points when judging the finger key position. Compared with the prior art, the method not only meets the requirement of the virtual keyboard and key miniaturization thereof, but also ensures that the key-press convenience is obviously increased because the operator does not need to erect the finger when pressing the key. The invention can be widely used in the handheld electronic product with the touch screen mobile phone as a representative.

Description

technical field [0001] The invention relates to key input of a virtual keyboard of a touch-screen mobile phone, in particular to a method for the touch-screen mobile phone to judge the finger keys of the virtual keyboard. Background technique [0002] In order to solve the problem of misjudgment of the finger button because the finger first touches other adjacent buttons when pressing the button, the current existing technology adopts the method of increasing the size of the virtual keyboard or increasing the distance between the two buttons. method, although this can reduce the possibility of touching other adjacent keys first when the finger is pressed, but there are too many screens occupied by the virtual keyboard, and when the operator uses the thumb to input the key, the operation range is too large, resulting in inconvenience, etc. question. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and ...
