Description of the Invention: [Technical Field] The present invention relates to the field of operation of navigation buttons for electronic devices, and more particularly to an electronic device having navigation buttons and a navigation method implemented therewith. [Previous Technology] [0002] Most mobile electronic devices, such as mobile phones, have navigation keys. Navigation keys can have different performances, but the main functions are five aspects: controlling the cursor up and down, moving left and right, and determining/launching the selection. Content. [0003] The capacitive touch buttons used in existing mobile electronic devices all implement the function of a five-way key with five keys of hardware. The specific control method is as follows: When the user only presses a single button in the up/down/left/right/0K of the five-way button area, the button touch panel will generate the signal of the current button press and process accordingly; When pressing the two buttons of up/down/left/right/〇κ in the five-way key area, the button touch panel generates the signals of the buttons with more contact areas among the two buttons, and performs corresponding processing. However, in the case where the area of the five-way key is small, the hardware mode of the month v will be poor and the misoperation will be easy. SUMMARY OF THE INVENTION It is necessary to provide a navigation button (4) sub-device and a navigation method implemented thereby to reduce erroneous operations. & _] - Navigation method for an electronic device having a navigation button 1 Navigation button includes at least one pair of relative buttons. The method includes: [0007] activating an electronic device to detect whether there is a user's touch input operation. 099131328 Form nickname A0101 Page 4 of 22 201211831 LU_ [0009] [0010] 00 [0012] 产生 Generate and transmit a touch signal reflecting the touch location. Determining a coordinate of the touch position, and reading a pre-stored button and coordinate area correspondence table, comparing the determined coordinate of the touch position with a coordinate area defined in the table, and determining a button where the coordinate of the touch position is located The coordinate area defined in the correspondence table with the coordinate area. According to the determined touched coordinate area, it is determined whether the coordinates corresponding to the touch position fall into the coordinate area corresponding to the two buttons of the pair of opposite buttons at the same time. When the shoulder net corresponding to the right touch position falls into the coordinate area corresponding to the two buttons of the pair of opposite buttons, the “confirm” function is executed. An electronic device having a navigation button, the navigation button includes at least a pair of opposite buttons, the electronic device includes a touch controller, a touch sensing unit, a main processor and a storage unit, wherein the touch sensing unit is configured to detect a user A touch operation on the navigation button and a touch signal reflecting the touch position. The storage unit is configured to store a correspondence between a button and a coordinate area. The button corresponds to a coordinate area. The win table is used to define a correspondence between the button and the coordinate area. The touch controller includes a touch area determination module, a button determination module, and a main processor. The touch area determining module is configured to receive a touch signal generated by the touch sensing unit, determine a coordinate of the touch position, and read a correspondence table between the button and the coordinate area, and determine a coordinate of the touch position and a coordinate defined in the table. The coordinate area is compared to determine the coordinate area defined in the correspondence table between the button and the coordinate area where the coordinate of the touch position is located. The touch (four) domain determination module is also used to determine whether the coordinates corresponding to the touched touch area are the same as the 099131328 form number Α0101 5th buy/total 22 pages 0992054895-0 201211831 when falling into a pair of relative buttons Within the coordinate area corresponding to the key. When the coordinate corresponding to the touch position falls into the coordinate area corresponding to the two buttons of the opposite button, the button is determined to be determined according to the corresponding relationship table of the button 盥 coordinate area, and the seat is determined. The button corresponding to the field. Qiao is the confirmation button. The main material is determined according to the button to determine the determined button to perform the "confirmation function. The circle provides the (four) sub-device relative to the cash-operated technology. In the electronic device provided with the capacitive touch button, the five-way key region is changed to four-way. In the case of using 'If the user selects more than two buttons because they are not paying attention, the area of the touched coordinates and the touch area can be used to determine the number of touched buttons' to prevent misoperation in advance. In the case of the user terminal, the convenience of the user terminal is further provided. [0014] In addition, in the case where the overall area of the touch area of the electronic device is constant, the area of the four buttons can be increased to increase the sensitivity of the button. Thus, the user's touch area can also be enlarged, which is more advantageous for the user's manual operation. [Embodiment] [0015] The present invention will be further described in detail below with reference to the accompanying drawings. [0016] Please refer to FIG. The electronic device 1 of the present invention includes a display screen 2 and a navigation button 3 °. In the present embodiment, the electronic device 1 is a mobile phone. In other embodiments, the electric device The sub-device 1 can also be a fixed-telephone, an e-book, etc. The navigation button 3 is a capacitive touch-type four-way navigation button, which is disposed on the casing of the electronic device 1 for responding to the user's touch operation. The navigation button 3 includes four basic buttons: an up button 3 〇, a down button 31, a left button 32, and a right button 33, respectively for responding to the user's touch 099131328 Form No. A0101 Page 6 of 22 Buy 0992054895 -0 201211831 ^ [0017] 〇 ' ' generates a corresponding control signal. In the present embodiment, the control signals generated by the up button 30, the down button 31, the left button 32, and the right button 33 are upward, Down, left, and right control signals. And, when entering different user interfaces, the function of the basic buttons of the navigation button 3 will change accordingly. [When in the text reading interface, the left button 32 functions as "PageUp" The function of the right button 33 is "PageD〇wn". The navigation button 3 can also be a mechanical button, which is disposed on the electronic device to respond to the user's click operation. Referring to FIG. 2, the electronic device 1 further includes a touch controller 1, a touch sensing unit 11, a main processor 12, and a storage unit 13. The storage unit 13 is configured to store a button and coordinate area correspondence table. The four basic buttons of the navigation button 3 disposed on the electronic device 1 are up button 3 〇, down button 31 , left button 32 , and The right button 33 will occupy a certain area', that is, each button necessarily corresponds to a standard field. Therefore, the correspondence table between the button and the coordinate area defines the correspondence between the button and the coordinate area. For example, the coordinate area corresponding to the up button 30 is formed by the coordinate point (2〇' 2〇) and the seat sample point (35, 50). The 'straight line is a diagonal rectangular area'. The coordinate area corresponding to the down button 31 is (40, 20) and the line formed by the coordinate point (50, 50) is a diagonal rectangular area, and the left button 32 corresponds. The coordinate area is a rectangular area in which the straight line formed by the coordinate point (15, 20) and the coordinate point (20, 50) is a diagonal line, and the coordinate area corresponding to the right button μ is a coordinate point (1 5, 4 0 ) and The line formed by the coordinate points (2 〇, 70) is a rectangular area of the diagonal. [0018] The touch sensing unit 11 is configured to detect a touch operation of the navigation button 3 by the user and generate a touch signal reflecting the touch position. 099131328 Form No. A0101 Page 7 of 22 0992054895-0 201211831 [0019] The touch controller 10 includes a touch area determining module 100 and a button determining module 101. The touch area determining module 100 is configured to receive a touch signal generated by the touch sensing unit 11, determine a coordinate of the touch position, and read a correspondence table between the button and the coordinate area stored in the storage unit 13, and determine the touch position. The coordinates of the coordinate are compared with the coordinate area defined in the table, and the coordinate area defined in the correspondence table between the button and the coordinate area where the coordinate of the touch position is located is determined. The button determining module 101 determines a button corresponding to the coordinate area according to the button and the coordinate area correspondence table. The main processor 12 executes the corresponding function according to the button determined by the button determining module 101. [0020] Generally, the user selects a button on the touch screen, most of which utilizes a finger end or a stylus. Since the setting of the buttons on the touch screen is too concentrated and the occupied area is small, when the user performs a selection operation by using the finger end or the stylus, a situation in which the selected button and its adjacent button are simultaneously touched occurs, and a misoperation occurs. Accordingly, the present invention will be directed to a user touching a button and simultaneously touching at least two buttons, both of which are separately described. [0021] A case where the user touches only one button at a time: when the touch area determining module 100 receives the touch signal, and determines that the coordinates of the touch position are located in the same coordinate area, it is determined that the user only touches the area of the navigation button 3 One of the buttons. For example, after the touch area determination module 100 receives the touch signal of the touch sensing unit 11, and determines that the coordinates corresponding to the touch position are A (20, 25) and B (25, 35), it can be determined that the touched area is located upward. The button 30 corresponds to the coordinate area. Then, the button determining module 101 determines the coordinate area according to the correspondence table between the button and the coordinate area. 099131328 Form No. A0101 Page 8 / Total 22 Pages 0992054895-0 201211831 [0022] Ο [0023] ❹ The button is the up button 3 (). The button determines that the result of the break is transmitted to the main processor 12, which performs the function of the determined up button 30. The touch controller 1 further includes an area calculation module m and a ratio calculation = group 103. For the case where the user touches at least two buttons at the same time: when the touch area determining module determines the coordinates corresponding to the touch position according to the received touch signal, the coordinate corresponding to the up button 3 () and the down button 31 The H axis, the job area determination touch (10) determines that the button corresponding to the coordinate area is a (10) button according to the button and coordinate area correspondence table, and transmits the result of the determination to the main processor 12, and the main processor 12 executes "Confirmation" function Thus, the function of the five-way navigation button is realized by the four-way navigation button 3, and one button is reduced compared with the prior art, thereby further avoiding the possibility of erroneous operation. The details are described below. The coordinate area corresponding to the "confirm" button function defined in the button and coordinate area correspondence table stored in the storage unit 13 is the button coordinate area corresponding to the up button 3 及 and the button coordinate area corresponding to the down button 31, For example, the button coordinate area corresponding to the "confirm" button function is: • a rectangular area where the line formed by the coordinate point (20, 20) and the coordinate point (35, 50) is a diagonal line, and the coordinate point (40, 20) And the line formed by (50, 50) is a rectangular area of diagonal. When the touch area calling module 100 determines, according to the received touch signal, the coordinate A (25, 45) and the coordinate B (45, 45) of the touch position are respectively located in the key coordinate area corresponding to the up button 30 and the down button 31. In the middle, the touch area determining module 100 determines, according to the touch function and the coordinate area correspondence table, that the button corresponding to the determined coordinate area is a “confirmation” function, and determines the 099131328 form number A0101, page 9 / total 22 pages 0992054895 The result of -0 201211831 is passed to the main processor 12, which performs the "confirm" function. [0024] If the touch area determining module 1 determines that the coordinates corresponding to the touch position do not fall into the coordinate area corresponding to the up button 30 and the down button 30, for example, the touch region determining module 100 determines that the touch position corresponds to The relevant seats are shown as A (20, 25), B (20, 35), C (15, 20), D (15, 35), then it can be judged that the touched area is located at the up button 3 〇 and left The button 32 is in the coordinate area corresponding to the two adjacent buttons. At this time, the touch area determining module 1 transmits the coordinates of the touch position to the area calculating module 1〇2', and the area module 102 receives the coordinates of the touch area and calculates coordinates corresponding to the touch position respectively. The two pairs of adjacent buttons correspond to the number of seats in the coordinate area, thereby determining the area in which the two buttons of the pair of adjacent buttons are respectively touched. The ratio calculation module 103 is configured to compare the calculated touched area with the preset button areas of the pair of adjacent buttons, and obtain a ratio of a touched area to a corresponding preset button area. And the ratio value is transmitted to the button determining module 101. The preset button area is the area occupied by the preset coordinate area corresponding to each button. [0025] The button determining module 101 is further configured to compare the received scale value with a coordinate region corresponding to a touch region having a larger ratio value, and determine the coordinate region according to the determined coordinate region. The main processor 12 executes the button function corresponding to the button. Specifically, for example, the touch area determining module 1 determines that the associated coordinates A (20 '25), B (20, 35) are located in the key coordinate area of the up button 30, and the area of the touch is calculated as S'. , coordinates C(15,20), D(15 099131328 Form No. A0101, page 10/22, 0992054895-0 201211831, 35) are located in the button coordinate area corresponding to the left button 32, and the calculated touch area is S, 2 . The preset button area of the up button 30 is s, and the button area preset to the left button 32 is \, and the scale calculation module 1〇3 compares S' 〇 and 8' 2 with 3() respectively to obtain the touch. The ratio of the area to the corresponding preset button area is γ (ie s, 1 Q / Ο ^ ) and (ie S' z/S2). The button determination module 101 compares Y1 with γ: if Υ>>Υ2, it is determined that the touched button is the up button 3〇, and the main processor 12 performs the “up,” function. If γ/%, the button The determining module ιοί determines that the touched button is the left button 32, and the main processor 12 performs the left button function. Referring to FIG. 3, the navigation button of the present invention includes a flowchart for implementing the button function, including: [0028] Step S400, the mobile electronic device i is activated, and the touch sensing unit detects whether there is a user's touch input operation. If the touch sensing unit u detects a touch action, the process proceeds to step S4〇1; otherwise, [0029] Step S401, the touch sensing unit 11 detects that the user touches the navigation button 3, generates a touch signal reflecting the touch position, and transmits the touch signal to the touch area determining module. 1] [Step S4〇2] The touch area determining module 1 receives the touch signal generated by the touch sensing unit 11, determines the coordinates of the touch position, and reads the key stored in the storage unit 13 Coordinate area pair In the relationship table, the coordinate of the determined touch position is compared with the coordinate area defined in the table, and the button where the coordinate of the touch position is located is determined to correspond to the coordinate area. 099131328 Form Compilation ίοι Page 11 of 22 0992054895-0 201211831 is a coordinate area defined in the table. [0031] Step S403, the touch area determining module 100 determines whether the coordinate corresponding to the touch position falls within the coordinate area corresponding to the up button 30 and the down button 31, if The touch area determining module 100 determines that the coordinates of the touch position fall into the coordinate area corresponding to the up button 30 and the down button 31, and proceeds to step S404; otherwise, proceeds to step S405. # [0032] Step S404, the touch The area determining module 100 determines that the button corresponding to the coordinate area is a "confirm" button according to the button and coordinate area correspondence table, and transmits the result of the determination to the main processor 12, and then proceeds to step S41 0. [0033 Step S405, the touch area determining module 100 determines whether the coordinates corresponding to the touch position are based on the determined touched coordinate area. When the key falls within the coordinates of a pair of adjacent two areas corresponding to a key, if yes, the process proceeds to step S406; otherwise, the process proceeds to step S409.

For example, when the touch area determining module 100 determines that the coordinates of the touch position are respectively located in different coordinate areas according to the coordinate area where the coordinates are located, for example, the touch sensing unit 11 transmits the touch to the touch area determining module 100. The coordinates are A (20,25), B (20,35), C (15,20), D (15, 35), then you can judge the touched area 099131328 Form No. A0101 Page 12 / Total 22 Page 0992054895- 0 201211831 is located in the button coordinate area corresponding to the up button 30 and the left button 32 respectively.

The button areas of the two buttons are respectively compared, and a ratio of a touch area to a corresponding preset button area is obtained, and the ratio value is transmitted to the button determination module 101. The preset button area is the area occupied by the preset coordinate area corresponding to each button.
