Hereinafter, for the sake of brevity, a slide type mobile terminal among various types of mobile terminals such as a folding type, a bar type, a swing type, a slide type mobile terminal, and the like will be described as an example. Therefore, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in FIG. 1 may be configured to operate using a communication system such as a wired and wireless communication system and a satellite-based communication system that transmits data via frames or packets.

A communication system in which a mobile terminal according to the present invention can be operated will now be described with reference to FIG.

Such communication systems may use different air interfaces and/or physical layers. For example, air interfaces used by communication systems include, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)). ), Global System for Mobile Communications (GSM), etc. As a 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, a CDMA wireless communication system can include a plurality of mobile terminals 100, a plurality of base stations (BS) 270, a base station controller (BSC) 275, and a mobile switching center (MSC) 280. The MSC 280 is configured to interface with a public switched telephone network (PSTN) 290. The MSC 280 is also configured to interface with a BSC 275 that can be coupled to the base station 270 via a backhaul line. The backhaul line can be constructed in accordance with any of a number of well known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. It will be appreciated that the system as shown in FIG. 2 can include multiple BSCs 275.

Each BS 270 can serve one or more partitions (or regions), each of which is covered by a multi-directional antenna or an antenna directed to a particular direction radially away from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS 270 can be configured to support multiple frequency allocations, and each frequency allocation has a particular frequency spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of partitioning and frequency allocation can be referred to as a CDMA channel. BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" can be used to generally refer to a single BSC 275 and at least one BS 270. A base station can also be referred to as a "cell station." Alternatively, each partition of a particular BS 270 may be referred to as a plurality of cellular stations.

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 Figure 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 helps locate at least one of the plurality of mobile terminals 100.

In Figure 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information can be obtained using any number of satellites. The GPS module 115 as shown in Figure 1 is typically configured to cooperate with the satellite 300 to obtain desired positioning information. Instead of GPS tracking technology or in addition to GPS tracking technology, other techniques that can track the location of the mobile terminal can be used. Additionally, at least one GPS satellite 300 can selectively or additionally process satellite DMB transmissions.

As a typical operation of a wireless communication system, BS 270 receives reverse link signals from various mobile terminals 100. Mobile terminal 100 typically participates in calls, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within a particular BS 270. The obtained data is forwarded to the relevant BSC 275. The BSC provides call resource allocation and coordinated mobility management functions including a soft handoff procedure between the BSs 270. The BSC 275 also routes the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, PSTN 290 interfaces with MSC 280, which forms an interface with BSC 275, and BSC 275 controls BS 270 accordingly to transmit forward link signals to mobile terminal 100.

Based on the above-described mobile terminal hardware structure and communication system, various embodiments of the method of the present invention are proposed.

As shown in FIG. 3, the touch screen of the conventional mobile terminal is divided into a touchable operation area (hereinafter referred to as A' area) and a key area (hereinafter referred to as B area).

The A' area is a touchable operation area for detecting touch point coordinates; the B area is a key area for detecting a menu key, a Home key, a return key, and the like.

Based on the traditional touch screen division method, in order to prevent misoperation, the present invention proposes two anti-missing schemes: one is to divide the virtual border area (hereinafter referred to as C area) in the A' area by a fixed method, and one is adopted. The free setting mode divides the C area in the A' area. For division from the A' area The touch operation in the A area remaining after the C area is still in accordance with the existing normal processing mode; for the touch operation in the divided C area, it can be defined as a special processing mode, such as ignoring processing, special effect processing, and the like. This will be described in detail below.

Embodiment 1

As shown in FIG. 4, the sliding identification method of the virtual frame area in this embodiment is applicable to the two division modes of the C area, and specifically includes the following steps:

401. Sense a touch event concurrent with the contact in the virtual border area.

402. Report the current coordinate position of the contact in real time, and determine whether the touch event concurrent with the contact belongs to a sliding event according to the initial coordinate position and the current coordinate position of the contact.

403. If it is determined that the touch event belongs to a sliding event, further determine a direction attribute of the sliding event.

Embodiment 2

In this embodiment, the C area is divided by a fixed manner, and the dividing method is: dividing a partial area as a virtual border area (ie, C area) at an edge of the original A′ area of the touch screen, and other areas of the A′ area are referred to as an A area. (Same as the conventional function); the C area includes a partial area on the left side and a partial area on the right side, and the position is fixedly disposed on both side edges of the A' area, as shown in FIG. Of course, it is also possible to divide the C area only at one side edge.

As shown in FIG. 6, when the C area is divided in a fixed manner, the sliding recognition method of the C area includes the following steps:

601. Define a position and a width of the C area, and divide the entire touchable area of the touch screen into a C area located at both side edges and an A area located at the middle. The effect diagram after division is shown in Figure 7, and the area on both sides of the touch screen is the C area.

602. When the touch screen driver is initialized, two input devices are allocated by input_allocate_device() (for example, input0 and input1 respectively), and the two input devices are registered by input_register_device(), where input0 corresponds to C area, input1 corresponds to Area A.

After the two virtual input devices are registered, the upper layer will identify whether the current user touch area is the C area or the A area according to the naming of the virtual input device reported by the driver layer, and the upper layer has different processing modes, and the upper layer processing manner is different. Will introduce.

The upper layer of the present invention generally refers to a framework layer, an application layer, and the like. In a system of a mobile terminal, a customized system such as android or IOS usually includes an underlying layer (physical layer, driving layer) and an upper layer (frame layer, application). Layer), the direction of the signal flow is: the physical layer (touch panel) receives the touch operation of the user, the physical compression is converted into the electrical signal TP, and the TP is transmitted to the driving layer, and the driving layer analyzes the pressed position to obtain the position. The specific coordinates, duration, pressure and other parameters of the point are uploaded to the framework layer. The communication between the framework layer and the driver layer can be realized through the corresponding interface. The framework layer receives the input device of the driver layer and parses the input device. The input device is selected to respond or not respond to the input device, and the valid input is passed up to which specific application to meet the application layer to perform different application operations according to different events.

603. When the C area senses a touch event concurrent with the contact, the initial coordinate position (downX, downY) and the initial pressed time information (downTime) of the contact are reported to the upper layer through the virtual input device input0, and the upper layer ( The system framework layer or application layer) records this information as a basis for subsequent sliding judgment. As shown in FIG. 8, the middle portion of the touch screen is the A area, the narrow sides on the left and right sides are the C area, and the gray origin represents the contacts in the C area.

The touch operation is usually a click, slide, etc., and each touch operation is composed of one or more contacts, so that the mobile terminal can determine that the touch operation is generated by detecting the area where the contact of the touch operation falls. In Area C or Area A.

After receiving the reported event in the framework layer (the reported event includes the input device and the parameters of the touch point, etc.), first, according to the naming of the input device, which region is identified, such as the driver layer (kernel) identification is in C For zone touch, the input device reported to the frame layer by the driver layer is input0 instead of being reported by input1. That is, the frame layer does not need to determine which partition the current contact is in, nor does it need to determine the size and position of the partition. The judging operation is completed on the driving layer, and the driving layer not only reports which input device is specifically, but also reports various parameters of the contact to the frame layer, such as pressing time, position coordinates, pressure magnitude and the like. That is to say, the driver layer determines whether the event occurs in the A zone or the C zone, and then reports the frame layer through the input device; the frame layer determines whether it is an event of the A zone or an event of the C zone according to the naming of the input device, that is, for example, input0 It is the event in Area C, and input1 is the event in Area A.

604. During the movement of the contact, the virtual input device input0 reports the current coordinate position (currentX, currentY) of the contact to the upper layer in real time according to a preset period; meanwhile, the upper layer is touched according to the touch. The initial coordinate position of the point and the current coordinate position information determine whether the touch event is a sliding event, and if so, further determine its direction attribute, and perform preset special processing according to this, and special processing methods such as ignoring, generating special effects, and the like.

To achieve a more accurate judgment, the reporting period of the virtual input device input0 can be set to a shorter time value, such as 1/85 second.

In step 604, the specific method for determining whether the touch event generated by the contact is a sliding event is: determining a moving distance between the current position of the contact and the initial position; and if the moving distance exceeds a preset threshold, determining the touch event For a sliding event, otherwise, it is determined that the touch event is not a sliding event.

The formula for calculating the moving distance of the contact is:

Since the C area is a virtual border area, the general setting is relatively narrow, and the moving distance in the X-axis direction is reduced, which can be neglected. Therefore, the calculation formula of the moving distance of the above contact can be simplified as:

Move distance =|currentY–downY|.

In step 604, the method of determining the sliding direction of the contact is: comparing the current position of the contact with the Y-axis coordinate value of the initial position, and if currentY>downY, determining that the sliding direction of the contact is downward, otherwise determining the sliding The direction is up.

It should be noted that after receiving the reported event, the framework layer reports to the application layer through a single-channel to multi-channel mechanism. Specifically, the channel is first registered, the reported event is transmitted through the channel, and the event is listened to by the listener, and the event is transmitted to the corresponding application module through different channels to generate different application operations, where the application The module includes common applications such as camera and contacts; it generates different application operations. For example, in the camera application, when the user clicks in a special zone, it will produce different operations such as focusing, shooting, and adjusting camera parameters. It should be noted that before the report event is delivered to the listener, it is a single channel. After the listener listens, the reported event is multi-channel, and multiple channels exist at the same time. The advantage is that it can be transmitted to different application modules at the same time, and different application modules are generated. Different response operations.

Optionally, the specific implementation of the foregoing steps is: using an object-oriented manner, defining a category and an implementation manner of the C area and the A area, and after determining that the area is C, converting the coordinates of the touch points of different resolutions by using the EventHub function. Define single channel functions (such as serverchannel and Clientchannel, etc., the function of this function is to pass the event to the event manager (TouchEventManager) through the channel after receiving the reported event, and pass the event to multiple through the multi-channel simultaneously or one by one through the listener's monitoring. The responding application module can also be passed only to one of the application modules, such as camera, gallery, etc., and different application modules generate corresponding operations. Certainly, the specific implementation of the foregoing steps may also be implemented in other manners, which is not limited by the embodiment of the present invention.

Referring to FIG. 9 , the touch operation flow of the present invention will be further described in another manner. For the sake of simplicity, in FIG. 9 , the virtual border area is simply referred to as the C area, and the other areas are simply referred to as the A area, and the touch event is abbreviated. The reporting process is as follows:

The driving layer receives the touch event through physical hardware such as a touch screen, and determines whether the touch operation occurs in the A area or the C area, and reports the event through the device file node of the A area or the C area. The Native layer reads events from device files in Areas A and C, and processes events in Areas A and C, such as coordinate calculations. The devices in the A and C areas are distinguished by the device ID, and finally the A area is distributed. And zone C events. The A area event takes the original process, and the A area event is processed in the usual way; the C area event is distributed from the dedicated channel of the C area registered in the Native layer in advance, and is input by the Native port, and the system port is output to the C area. The system service then reports the external interface to each application through the C area event.

Correspondingly, as shown in FIG. 10, the embodiment further provides a mobile terminal, including:

The C area fixed dividing unit 1010 is configured to define the width of the C area, and divide the entire touchable area of the touch screen into a C area located at both side edges and an A area located in the middle, and the position and size of the C area are fixed and cannot be adjusted.

The bottom layer reporting unit 1020 is configured to allocate and register two virtual input devices when the touch screen driver is initialized, corresponding to the C area and the A area respectively; when the contact is pressed in the C area, the virtual input device of the C area reports the touch The initial coordinate position and initial time information of the point, and the current coordinate position is reported in real time according to the preset period during the movement of the contact.

The slide recognition unit 1030 is configured to record the initial coordinate position and the current coordinate position information of the contact reported by the bottom layer reporting unit 920 to determine in real time whether the contact has a sliding and sliding direction.

The sliding recognition unit 1030 further includes:

The recording module 1031 is configured to record initial coordinate position and initial time information of the contact reported by the bottom reporting unit 1020, as a judgment basis for subsequent sliding;

The sliding event judging module 1032 is configured to calculate a moving distance of the contact according to the initial coordinate position of the contact and the current coordinate position, and determine whether the contact has slipped by comparing the moving distance with a preset threshold;

The sliding direction determining module 1033 is configured to determine the sliding direction of the contact by comparing the initial Y-axis coordinate value of the contact with the current U-axis coordinate value.

In this embodiment, by dividing the fixed virtual border area, the touch operation in the virtual border area is specially processed, which can effectively solve the problem that the narrow border and the borderless terminal are prone to accidental touch, and can quickly and accurately identify Whether the contacts in the virtual frame area have a sliding direction and a sliding direction lay the foundation for the subsequent effective execution of the corresponding special processing operations.

Embodiment 3

In the second embodiment, the C area adopts a fixed division manner, that is, the size of the C area is not variable, which affects the user experience. Therefore, in the third embodiment, the division manner of the C area is improved, and the number, position, and size of the C area are freely set, thereby improving the user experience.

To this end, the present embodiment replaces the C-area fixed dividing unit 1010 in the mobile terminal with:

The C area sets the interface for creating and modifying the number, location, and size of the C area.

The interface is implemented in the driver layer, and the upper layer can call the interface to adjust the number, location and size of the C area at any time according to its own needs. Generally, the basic graphic design of the C area is a rectangle, and the position and size of the C area can be determined by inputting the coordinates of the two vertices of the diagonal of the graphic. As shown in FIG. 11, the figure creates two C areas on the lower left side and the lower right side of the touch screen. In specific implementation, all C areas may correspond to one virtual input device.

In order to meet the usage habits of different users for different applications, it is also possible to set multiple sets of C-zone setting schemes applied in different application scenarios. As shown in Figure 12, under the system desktop, because the icons occupy more places, the width of the C areas on both sides is relatively narrow. As shown in Figure 13, when the camera icon is clicked to enter the camera application, the C area setting interface can be called through the upper layer to set the number, position and size of the C area under this scene. The C area width can be set relative without affecting the focus. It is wider.

2) Open the specified application function: preset the corresponding application type for different sliding directions in advance; when the C area senses the up/down sliding event, open the corresponding corresponding application. Through this function, users can set one or two applications with the highest frequency of use according to their own usage habits, overcoming the time-consuming and laborious defects of the traditional way (finding a specific application from many applications on the desktop).

3) Return function: When the C area senses an up/down sliding event, the upper layer immediately performs a return operation. With this function, the user no longer has to press the physical button at the bottom of the display or the virtual return button on the touch screen, which greatly increases the convenience of operation.
