By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 2750.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295.

In the embodiment of the present invention, after the keyboard acquisition module acquires the gray selection keyboard, the gray selection keyboard is further displayed on the display interface, and there are two display modes, one mode is: the display module 802 displays the first type of virtual keys contained in the acquired gray keyboard, and enlarges the display area occupied by the first type of virtual keys in the gray keyboard based on the size of the display area occupied by the virtual keys, specifically, only the first type of virtual keys can be displayed, but not the second type of virtual keys, so that the number of the displayed keys is reduced, under the condition, the display area occupied by the first type of virtual keys during display can be properly increased, the display area of the gray keyboard is as large as the display area of the virtual keyboard, and because the display area occupied by the first type of virtual keys during display is increased, the user can more conveniently click the keys, mistaken touch is effectively avoided, and the operability is improved. The other mode is as follows: the display module 802 displays the first type of virtual keys and the second type of virtual keys included in the obtained gray selection keyboard, and the second type of virtual keys are different from the first type of virtual keys by a preset marking mode, where the preset marking mode may be gray display, and refer to fig. 6 specifically, where the gray square part is the second type of virtual keys.

In the embodiment of the invention, the gray selection keyboard corresponding to the matched false touch prevention fingerprint features is obtained and displayed, so that the first type of virtual keys can be effectively displayed, and false touch is avoided.

Based on the embodiments shown in fig. 3 and fig. 6, the mobile terminal further includes:

a switching module (not shown in the figure), configured to switch and display a next gray keyboard according to a preset switching rule if the detecting module 303 detects a gray keyboard switching instruction.

In the embodiment of the present invention, a user may further switch a gray keyboard, and specifically, the user may switch the gray keyboard through a preset switching gesture, such as a fit gesture, where for at least one gray keyboard matched with a fingerprint feature input by the user, the switching may be performed based on priorities, for example, sequentially switching from a gray keyboard with a highest priority to a gray keyboard with a lowest priority, and when the gray keyboard with the lowest priority is displayed, if the switching gesture is further detected, switching the gray keyboard with the lowest priority to the gray keyboard with the highest priority.

In the embodiment of the invention, the user can switch the displayed gray selection keyboard in a manner of switching the gray selection keyboard, so that a more flexible and abundant gray selection keyboard is provided for the user.

Please refer to fig. 9, which is a flowchart illustrating a method for preventing a virtual keyboard from being touched by mistake according to a third embodiment of the present invention, the method includes:

step 901, if a calling instruction of a virtual keyboard is detected, displaying the virtual keyboard;

step 902, if a false touch prevention instruction is detected, acquiring and displaying a preset grey selection keyboard of the virtual keyboard, wherein the grey selection keyboard comprises a first class of virtual keys and a second class of virtual keys, the first class of virtual keys can respond to a character input gesture, and the second class of virtual keys cannot respond to the character input gesture.

In the embodiment of the invention, when a user needs to input characters, for example, when the user needs to input a password, a call instruction of the virtual keyboard is generated, and after the call instruction of the virtual keyboard is detected, the virtual keyboard is displayed.

In the embodiment of the invention, if the false touch prevention instruction is detected, the mobile terminal acquires and displays the preset grey selection keyboard of the virtual keyboard, wherein the grey selection keyboard comprises the first class virtual keys and the second class virtual keys.

It can be understood that, after displaying the grayed-out keyboard, the grayed-out keyboard and the virtual keyboard may be switched according to specific conditions, for example, the grayed-out keyboard may be displayed only in a scenario of password input, so that when it is detected that the input field in which the user currently needs to input characters is the account input field, the input field may be switched to the virtual keyboard and displayed, and if it is detected that the input field in which the user currently needs to input characters is the password input field, the input field is switched to the grayed-out keyboard and displayed, so that the grayed-out keyboard may be used only in a specific scenario. And in order to protect the security of the user account, when the mobile terminal exits from the current input interface, the gray selection keyboard is closed, and when the mistaken touch prevention instruction is received again, the gray selection keyboard is acquired again and displayed.

In the embodiment of the invention, if a calling instruction of the virtual keyboard is detected, the mobile terminal displays the virtual keyboard, and if a false touch prevention instruction is detected, a preset grey selection keyboard of the virtual keyboard is obtained and displayed. Because the gray selection keyboard comprises the first type of virtual keys capable of responding to the character input gestures and the second type of virtual keys incapable of responding to the character input hand gestures, the error touch is reduced and the operability is improved by setting part of the virtual keys to be in a mode of not responding to the character input gestures, and the gray selection keyboard is particularly suitable for the password input scene and can effectively improve the use experience of users.

Based on the third embodiment shown in fig. 9, please refer to fig. 10, which is a schematic flow chart of a virtual keyboard false touch prevention method according to a fourth embodiment of the present invention, and based on the third embodiment shown in fig. 9, the schematic flow chart further includes the following steps:

1001, if a fingerprint input operation is detected, acquiring fingerprint features in input fingerprint data;

step 1002, searching a preset false touch prevention fingerprint feature set, and if a false touch prevention fingerprint feature matched with the fingerprint feature is found in the false touch prevention fingerprint feature set, generating a false touch prevention instruction.

In contrast to the third embodiment shown in fig. 9, the fourth embodiment shown in fig. 10 includes a fingerprint verification process, and only if the fingerprint verification is passed, the anti-false-touch command is generated. By the fingerprint verification, the password input safety can be further improved when the user inputs the password by using the gray selection keyboard.

In the embodiment of the invention, after the virtual keyboard is displayed, if a fingerprint input operation is detected, fingerprint features in input fingerprint data are acquired, a preset false touch prevention fingerprint feature set is searched, and if the false touch prevention fingerprint features matched with the acquired fingerprint features exist in the false touch prevention fingerprint feature set, a false touch prevention instruction is generated.

Referring to fig. 11, a flow chart illustrating a step of refining step 902 according to the embodiment of fig. 9 and fig. 10 of the present invention includes:

step 1101, if the matched false touch prevention fingerprint features correspond to a gray selection keyboard, acquiring the gray selection keyboard; step 1103 is executed;

1102, if the matched false touch prevention fingerprint features correspond to at least one grey selection keyboard, acquiring the grey selection keyboard with the highest priority in the at least one grey selection keyboard, and executing step 1103;

step 1103, displaying a first type of virtual keys included in the obtained gray selection keyboard, and enlarging a display area occupied by the first type of virtual keys in the gray selection keyboard based on the size of the display area occupied by the virtual keyboard, or displaying the first type of virtual keys and a second type of virtual keys included in the obtained gray selection keyboard, wherein the second type of virtual keys are different from the first type of virtual keys in a preset marking mode.

In the embodiment of the invention, if the false touch prevention fingerprint feature set contains the corresponding relationship between the false touch prevention fingerprint features and the gray keyboard, when the false touch prevention instruction is generated, the gray keyboard corresponding to the matched false touch prevention fingerprint features is carried in the false touch prevention instruction, so that when the mobile terminal receives the false touch prevention instruction, the number of the gray keyboards corresponding to the matched false touch prevention fingerprint features is determined, if only one corresponding gray keyboard is available, the gray keyboard is obtained, and if at least one corresponding gray keyboard is available, the gray keyboard with the highest priority in the at least one gray keyboard is obtained.

In the embodiment of the present invention, after the gray selection keyboard is obtained, the gray selection keyboard is also displayed on the display interface, and there are two display modes, one mode is: the first type of virtual keys contained in the acquired gray keyboard are displayed, the display area occupied by the first type of virtual keys in the gray keyboard is enlarged based on the size of the display area occupied by the virtual keys, specifically, only the first type of virtual keys can be displayed, the second type of virtual keys are not displayed, the number of the displayed keys is reduced, under the condition, the display area occupied when the first type of virtual keys are displayed can be properly increased, the display area of the gray keyboard is as large as the display area of the virtual keyboard, due to the fact that the display area occupied when the first type of virtual keys are displayed is increased, the user can more conveniently click the keys, mistaken touch is effectively avoided, and operability is improved. The other mode is as follows: displaying the first type of virtual keys and the second type of virtual keys included in the obtained gray selection keyboard, wherein the second type of virtual keys are different from the first type of virtual keys through a preset marking mode, the preset marking mode can be gray display, and specifically refer to fig. 6, wherein the gray square part is the second type of virtual keys.
