Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 shows a flow chart of a virtual key control method for a vehicle-mounted terminal according to an embodiment of the present application, where the method includes:

s101, when the vehicle-mounted terminal is in a first working mode, responding to a first touch operation on a screen of the vehicle-mounted terminal, and providing a first virtual key on the screen, wherein the first virtual key comprises a direction key positioned at a first position, the direction key comprises a determination key, an upper key, a lower key, a left key and a right key, and the first position corresponds to the position of the first touch operation;

s102, responding to a second touch operation on the screen, if a time interval between the triggering time of the second touch operation and the triggering time of the first touch operation is smaller than or equal to a preset threshold value, providing at least four virtual dividing lines around the direction key to divide the surrounding area of the direction key into at least four areas, wherein a first area of the at least four areas corresponds to an upper key, a second area of the at least four areas corresponds to a lower key, a third area of the at least four areas corresponds to a left key, and a fourth area of the at least four areas corresponds to a right key;

and S103, responding to a second touch operation on the screen, and if the time interval between the trigger time of the second touch operation and the trigger time of the first touch operation is greater than a preset threshold value, providing a second virtual key on the screen.

According to the embodiment of the application, when the vehicle-mounted terminal is in a first working mode, for example, in a mode of 'virtual key function activation', if a user performs touch operation on a screen, the user responds to the touch operation, a virtual key appears on the screen, the position of the virtual key is located at a position where the user lightly touches and clicks, the user does not need to specially see the screen with eyes to confirm the position of the key, but can directly confirm that the key is located at the clicking position, and can conveniently and directly click to perform the next operation;

wherein, this virtual button includes at least one direction button, is provided with on the direction button: determining a key, an up key, a down key, a left key and a right key, if the user clicks the screen again within a short time (e.g., 1 second, 1.6 seconds, 2.2 seconds, longer or shorter time), in response to the touch operation, at least four virtual division lines appear on the screen, an area of a 360-degree range around the direction key is divided into at least four areas, and the four areas correspond to the up key, the down key, the left key and the right key on the direction key, respectively. Here, taking a first area among the divided areas as an example, the first area corresponds to the up key, which means that the screen range of the first area corresponds to the function of the up key, and if the position where the user clicks the screen falls within the first area range, the terminal will perform the function of clicking the up key, for example, turning up the terminal's outgoing volume. Other areas, for example, the third area corresponds to the left key, and the contact point falling on the third area is equivalent to hitting the left key, so that the function of "playing the last song" can be realized. Here, since the divided control area is large and much larger than the area of one "up key", the function operation of the corresponding direction key can be realized without looking and confirming whether the click is accurate.

Moreover, if the user does not click the screen again in a short time, but clicks the screen again after a certain time (for example, more than 1 second, 1.6 seconds, 2.2 seconds, etc.), the virtual dividing line does not appear on the screen, but the virtual key, for example, the direction key, appears again at the position where the user clicks the screen again, the user can directly click on the basis of the virtual key appearing again to perform the next operation, for example, clicking a confirmation key to call, and the whole process of clicking many times does not need to use eyes to specially see the screen to confirm the key position. By analogy, a user can click the terminal screen at any time intermittently and repeatedly when needed, for example, in the driving process, the user can conveniently and directly enter the interface operation, and the user does not need to specially observe whether each key on the screen is displayed and where the key is displayed by eyes.

Therefore, by using the virtual keys and the control method of the virtual keys provided by the embodiment of the application, the virtual keys and the virtual dividing line can be called out by only touching any position of the screen with a light touch without observing the screen of the vehicle-mounted terminal with eyes when a user such as a vehicle driver or a passenger is driving, and a small distance moving finger can touch each large-area control area divided by the virtual dividing line with a light touch to directly and quickly trigger key events to control the current application degree of the terminal, so that blind touch control of the vehicle-mounted terminal by the driver or the passenger is realized to a great extent, the user can concentrate on observing road conditions in front of the vehicle, the user does not need to look at various functional keys (possibly changed along with dynamic apps of an application program) on the screen with a low head, and under the premise of improving driving safety of the user, the screen operation convenience is provided for the user to the maximum extent, and the diversified requirements of different users are met.

In some embodiments of the present application, the first virtual keys include at least one screen corner key located at a position of at least one of four corners of the screen in addition to the direction keys. The screen corner key is arranged on four corners of the screen, so that a user can conveniently position the screen corner key by touching the terminal edge with hands, and the user does not need to observe the screen corner key specially by eyes. The four corners of the screen can be quickly found out through the difference between the edge of the terminal and the screen, for example, the edge of the terminal and the screen are different in material and surface structure outline, and the corners of the screen are substantially right angles (for example, smooth right angles), so that the positions of the corner keys of the screen can be easily determined through hand touch, and the blind touch control of the vehicle-mounted terminal is more beneficial to realization of comprehensive blind touch control of the vehicle-mounted terminal.

The principle and thought of the virtual key and the control method designed by the embodiment of the application are described above, the "direction key" in the virtual key can be considered to form a direction key area, and a plurality of "screen corner keys" form a function key area. The virtual keys and their uses and benefits mentioned in the embodiments of the present application are described in detail below by way of a number of specific examples.

Fig. 2, fig. 3 and fig. 4 schematically show the effect of the in-vehicle terminal screen in different states according to the embodiment of the present application. The boxes in the drawing represent screens of the in-vehicle terminals.

Fig. 2 is an effect diagram of a user finger touching any position on the click screen, the click position is mostly in the range from the middle to the periphery of the large screen, and the fingerprint pattern on the screen in fig. 2 represents the touch position. According to the control method of the virtual key in the embodiment of the application, the virtual key is provided on the screen in response to the touch operation described in fig. 2.

Referring to fig. 3, virtual keys appear on the screen as an oval directional keypad, whose positions correspond to the fingerprint positions shown in fig. 2. In the embodiment shown in fig. 3, the direction keys are oval-shaped keyboards, and in other embodiments, the direction keys may also be round, square, rectangular, or irregular. It can be seen that the center of the direction key is an "OK" key, i.e. a confirmation key, and four triangular direction keys, i.e. an up key, a down key, a left key and a right key, are arranged around the direction key.

Note that four corner keys are also present at four corners of the screen shown in fig. 3, and they are all virtual keys, and the functions performed by the corner keys may be set according to requirements, for example:

the function of the upper left key is "show home screen",

the function of the button in the lower left corner is "go back to previous page",

the function of the key in the upper right corner is "set",

the function of the key in the lower right corner is "exit virtual key mode".

In other embodiments of the present application, the functions of the four screen corner keys can be set by the user in a user-defined manner, so as to provide convenience for the user in operation habits.

In other embodiments of the present application, the number of the screen corner keys may be less than four, and the positions may be selectable, for example, 2 screen corner keys appear only on the left side, or screen corner keys appear only on the upper left corner and the lower right corner, so that on the premise of providing certain convenience, the number of the keys is reduced, and the screen interface is kept simple.

In the embodiment of the application, a user may trigger the directional keyboard and/or the screen corner key by clicking the screen, and when the user clicks the screen again within a preset time interval (e.g., 1s), that is, a time interval between trigger times of two touch operations is less than or equal to a preset threshold (e.g., 1s), four virtual dividing lines with the directional keyboard as a center may appear on the screen as shown in fig. 4, and four quadrants obtained by the division correspond to the upper key, the lower key, the left key, and the right key, respectively.

As an example, the directional keyboard is associated with four quadrants around it, and the touch logic is as follows:

taking the center of the keyboard as a reference, judging that the distance between the touch position and the central point is within the radius of a confirmation key, and judging as a confirmation key;

secondly, taking the center of the keyboard as a reference, determining that the touch position is within a 45-degree area from the upper left to the upper right of the central point and is outside a confirmation key;

taking the center of the keyboard as a reference, determining that the touch position is in a region from 45 degrees at the left lower part to 45 degrees at the right lower part of the central point, and determining that the key is down when the touch position is beyond the confirmation key;

taking the center of the keyboard as a reference, determining that the touch position is in a region from the upper left 45 degrees to the lower left 45 degrees of the central point, and determining that the touch position is a left key when the touch position is not beyond the confirmation key;

and fifthly, taking the center of the keyboard as a reference, determining that the touch position is in a 45-degree area from the upper right to the lower right of the central point, and determining that the touch position is a right key when the touch position is not beyond the confirmation key.

Therefore, the user can easily click the screen again by slightly moving the finger, and the blind touch operation on the direction key can be completed as long as the contact point falls into the quadrant range, so that the time and the labor are saved.

In some embodiments of the application, the virtual dividing line can be displayed together when the user clicks the screen to trigger the virtual key for the first time, so that a complete virtual operation interface can be presented at the first time to prompt and guide the user to master various functions of blind touch operation as soon as possible.

In an embodiment of the application, in response to a second touch operation on the screen, if a time interval between a trigger time of the second touch operation and a trigger time of the first touch operation is greater than a preset threshold (for example, 1s), providing a second virtual key on the screen, and optionally, the function of the second virtual key is the same as that of the first virtual key; the direction key of the second virtual key is located at a second position, and the second position corresponds to the position of the second touch operation.

For example, after the user triggers the screen for the first time to call the virtual key, if the user does not trigger the screen for a long time, the virtual key is hidden or disappears; then, when a new touch operation is received, the virtual key is triggered again; the circulation is carried out, the user does not need to remember where the previous touch position is, but can directly start a new touch process at a new position, the user is helped to realize a friendly and convenient blind touch function, and the user experience is improved.

For another example, after the first touch operation, the second touch operation is not performed for more than 1 second, or after the virtual key is activated by the first touch operation, the second touch operation is not performed for more than 1 second, and the virtual key is automatically hidden or disappeared; until the user clicks the screen again within 1 second after clicking once, the corresponding key event is triggered, and a smooth blind touch control process is formed.

In addition, if the touch operation of the user is determined to be an erroneous operation, such as an undefined touch operation type (e.g., dragging), the virtual key disappears, and the user waits for the next touch operation.

In the embodiment of the application, optionally, the positions of the screen corner keys of the second virtual key and the positions of the screen corner keys of the first virtual key may be the same or different.

For example, for a virtual key triggered by a multi-touch instruction with a time interval between two adjacent touches greater than 1s at different times, the positions of the screen corner keys triggered each time may be the same (or the same group of) corners, for example, the screen corner keys triggered each time are all present in the lower left corner (or the lower left corner and the lower right corner, etc.); in other embodiments, the screen corner keys triggered for multiple times can also appear at different corners, or be dragged to different corners by the user, so that the people at different positions in the cab can conveniently control the keys nearby.

In the embodiment of the present application, optionally, in a case where the virtual key is hidden, if a touch operation is received at a position of a first corner of four corners of the screen, the screen corner key is provided at the position of the first corner.

Taking the first corner as the lower right corner of the screen as an example, under the condition that the virtual key working mode is activated and the virtual key is hidden, if the user only clicks (for example, continuously clicks twice) the lower right corner of the screen, the screen corner key appears at the lower right corner of the screen in response to the touch instruction, namely the function of the function key area is triggered, the function can be set to be a common key function, for example, a main screen 'home' key function, a simple and quick blind touch instruction can be sent out under the condition that a large screen interface is not affected, and the operation is easy.

In the embodiment of the application, the virtual keys, the virtual partition lines and the like on the screen can be provided in a form of one-layer suspension layer or a superposition of multiple layers of suspension layers, and when the vehicle-mounted terminal is in a common working mode, the suspension layer cannot be activated by the touch behavior of a user.

Optionally, the first operating mode of the vehicle-mounted terminal, such as the "virtual key function active" mode, may be activated by at least one of the following:

a) triggering a physical key of the vehicle-mounted terminal, such as continuously and briefly pressing a physical key for volume adjustment on a center console, and the like;

b) a button triggering an application interface of the vehicle-mounted terminal, such as a button in a home screen interface or a button in app;

c) voice wake-up, e.g., issuing a voice activation command;

d) the method is activated by an application program in the vehicle-mounted terminal, for example, the method is actively activated when video APP is used.

In the embodiment of the present application, the specific setting contents of the directional keypad and the functional keypad may be set by a program or according to user configuration according to different application scenarios and usage scenarios.

Based on the above, the virtual key capable of automatically tracking the finger position of the user is designed, and the detailed operation method is designed, so that the method can be applied to touch operation of various types of terminal equipment, and is particularly suitable for being used in a vehicle-mounted environment.

The specific arrangement and implementation of the embodiments of the present application are described above from different perspectives by way of a plurality of embodiments. In correspondence with the processing method of at least one embodiment described above, the present embodiment further provides a virtual key control device 100 for an in-vehicle terminal, and with reference to fig. 5, the virtual key control device includes:

the virtual key providing module 110 is configured to provide a first virtual key on a screen in response to a first touch operation on the screen of the vehicle-mounted terminal when the vehicle-mounted terminal is in a first operating mode, where the first virtual key includes a direction key located at a first position, the direction key includes a determination key, an up key, a down key, a left key, and a right key, and the first position corresponds to a position of the first touch operation;

the virtual key providing module 110 is further configured to provide a second virtual key on the screen in response to a second touch operation on the screen, where a time interval between a trigger time of the second touch operation and a trigger time of the first touch operation is greater than a preset threshold.

Optionally, in this embodiment of the application, the first virtual key further includes at least one screen corner key, and the at least one screen corner key is located at a position of at least one of four corners of the screen.

Optionally, in this embodiment of the application, the function of the second virtual key is the same as that of the first virtual key, the direction key of the second virtual key is located at a second position, and the second position corresponds to the position of the second touch operation; the position of the screen corner key of the second virtual key is the same as that of the screen corner key of the first virtual key.

Optionally, in this embodiment of the application, after the first virtual key appears, if the second touch operation is not received after exceeding a preset time range, the virtual key on the screen is hidden; the device still includes: the screen corner key providing module 130 is configured to, in a case where the virtual key is hidden, provide the screen corner key at a first corner position of four corners of the screen if a touch operation is received at the first corner position.

By using the embodiment of the application, the user only needs to touch the position of the screen, the direction key can be drawn by taking the finger contact as the center, and the user moves the finger again to click, so that the key click in the corresponding direction can be completed. The user does not need to accurately confirm the key position, can know which relative position the direction key is in, and the user can directly operate and click without looking over the screen to carry out blind operation. When the device is used on a moving non-stationary platform such as an automobile and the like, and a user cannot keep the screen relatively stable, the operation method can provide great convenience, because the user needs to ensure that the user can complete positioning by touching the screen with fingers.
