It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for an implementation.
With continued reference to fig. 2, a flowchart of one embodiment of a touch screen based terminal control method according to the present application is shown. The terminal control method based on the touch screen comprises the following steps:
step S201, detecting a sliding operation of a user on an annular touch screen of the terminal to record the number of touch points and coordinates of the touch points corresponding to the sliding operation, so as to obtain finger sliding data.
In this embodiment, an electronic device (for example, the terminal device shown in fig. 1) on which the touch screen-based terminal control method operates may communicate with the server through a wired connection manner or a wireless connection manner. It should be noted that the above-mentioned wireless connection means may include, but is not limited to, 3G/4G/5G connection, wiFi connection, bluetooth connection, wiMAX connection, zigbee connection, UWB (ultra wideband) connection, and other now known or later developed wireless connection means.

The user can contact the annular touch screen through a finger, and the finger slides on the annular touch screen in a rotating mode to achieve option selection. The annular touch screen detects the sliding operation of a user on the annular touch screen, and records the number of touch points and the coordinates of the touch points to obtain finger sliding data. When a user finger contacts the annular touch screen, touch points are arranged, and the number of the touch points can be the number of the fingers contacting the annular touch screen; in the sliding operation, the position of the touch point on the surface of the annular touch screen changes, and the touch point coordinate represents the position of the touch point.
Fig. 3 is a schematic diagram illustrating a sliding operation on the annular touch screen in an embodiment, specifically, referring to fig. 3, the novel knob is cylindrical, the measuring surface of the novel knob has an annular touch screen, and a user can obtain touch points by touching the annular touch screen with a finger, where the number of the touch points may be 2, 3, 4, and the like, and for example, four touch points a, B, C, and D may be included. And detecting the number of touch points of the user on the annular touch screen and the initial positions of the touch points to obtain the coordinates of the touch points. The touch point location may be at the origin of the center of the novel knob. In one embodiment, the coordinate of the vertical axis of the touch point, i.e. the y coordinate, is recorded to obtain the touch point coordinate. For example, there are two touch points a, B, where the initial Y-coordinate of touch point a is A0Y, the final Y-coordinate of touch point a is A1Y, the initial Y-coordinate of touch point B is B0Y, and the final Y-coordinate of touch point B is B1Y.
Step S202, calculating the finger sliding data according to a preset touch control algorithm to obtain first event information.
Specifically, the user selects candidate event information through a rotation operation, and the candidate event information may be an event or an option provided to the user for selection. For example, when the terminal is provided with a heating function, the candidate event information may be a heating range provided for selection by the user.
The user can contact the annular touch screen through fingers with different numbers, and rotation habits (such as rotation speed and rotation angle) are different when the numbers of the fingers are different, so that a touch control algorithm is preset, coordinates of touch points are calculated according to the number of the touch points in the finger sliding data, a rotation angle is obtained, an option selected by the sliding operation of the user is determined, and first event information is obtained. For example, if there are three touch points, the coordinates of the touch points are calculated to obtain a rotation angle, and the first event information corresponding to the rotation angle when there are three touch points is obtained as "scented tea".
In one embodiment, the finger swipe data is recorded in real-time and updated in real-time, such that calculations are performed in real-time based on the finger swipe data to determine current first event information in real-time.
And step S203, displaying the first event information through the terminal.
Specifically, the terminal may present first event information corresponding to the user sliding operation. The terminal may be provided with a display screen or a player, and the first event information may be displayed through the display screen or the player.
And step S204, detecting the pressing operation of the user on the annular touch screen to obtain second event information corresponding to the first event information.
Specifically, the user can switch between different candidate event information through a sliding operation, and after switching to certain first event information, the user can further select and control the first event information through a pressing operation.
The annular touch screen can be pressed by a user through fingers, and the pressure sensor detects the pressing operation of the user to obtain finger pressing data. The finger pressing data indicate different pressing states of the user, so that the first event information is further edited, selected, confirmed or exited, and second event information corresponding to the first event information is obtained.
And step S205, controlling the terminal according to the second event information.
Specifically, after the second event information is obtained, the terminal controls itself according to the second event information, and responds to the user operation.
In the embodiment, the number of touch points and the coordinates of the touch points of the sliding operation of a user on the annular touch screen of the terminal are detected to obtain finger sliding data; calculating the number of touch points and coordinates of the touch points through a touch control algorithm, so as to obtain and display first event information selected by a user through sliding operation; the user can select the first event information through pressing operation, the pressing operation of the user on the annular touch screen is detected, second event information corresponding to the first event information is obtained, and the terminal is controlled according to the second event information; according to the method and the device, the annular touch screen is used for replacing a rotating structure, the possible abnormity of the traditional rotating structure is avoided, and the control on the terminal is realized through the sliding or pressing operation of the user on the annular touch screen.
Further, before step S201, the method may further include: acquiring a page identifier of a current page of a terminal; selecting sliding prompt information corresponding to the page identification; and displaying the sliding prompt information through the terminal to prompt the user to perform sliding operation according to the number of preset touch points in the sliding prompt information.
Specifically, the terminal has a display screen, the display screen can implement page display, and different pages can implement control in different aspects, for example, page 1 can implement control of terminal image display, and page 2 can implement control of terminal sound playing. The number of candidate event information presented by the page may also be different due to different control functions associated with the page, for example, the above-mentioned page 1 controls the image display of the terminal from 4 aspects, and the above-mentioned page 2 controls the sound playing of the terminal from 6 aspects. When the number of fingers is different, the rotation angles of the fingers are also different, so that the number of touch points of a certain page can be predetermined for different pages, namely the number of fingers required to be used by the sliding operation of the user can be predetermined.
The method comprises the steps that a page identification of a page can be obtained, sliding prompt information corresponding to the page identification is selected, and the sliding prompt information comprises the number of preset touch points; the terminal can prompt a user through page display, voice prompt and other modes, and the annular touch screen is contacted according to the number of preset touch points to perform sliding operation. In one embodiment, the more candidate event information included in the page, that is, the more switching options, the more the number of preset touch points is.
In this embodiment, different sliding prompt messages are set for different pages to prompt a user to perform a sliding operation according to the number of preset touch points in the sliding prompt messages, so that the sliding operation is performed according to the number of switching options.
Further, the step S202 may include: checking whether the number of preset touch points is consistent with the number of touch points in the finger sliding data; when the first event information is consistent with the first event information, calculating the finger sliding data according to a preset touch control algorithm to obtain first event information; and when the sliding operation is inconsistent with the sliding operation, displaying the re-sliding information through the terminal to instruct the user to perform the sliding operation again.
Specifically, the sliding prompt information can be displayed through the terminal to prompt the user to perform the sliding operation according to the number of the preset touch points in the sliding prompt information. When a user contacts the annular touch screen through a finger and performs sliding operation, the number of touch points and the coordinates of the touch points of the sliding operation are recorded in real time, and finger sliding data are obtained.
Comparing whether the number of touch points in the finger sliding data is consistent with the number of preset touch points in the current page sliding prompt message in real time; if the first event information is consistent with the first event information, the user slides according to the sliding prompt information, and finger sliding data are calculated according to a preset touch control algorithm to obtain the first event information; if the sliding operation is inconsistent with the sliding operation, the sliding operation is performed according to the preset touch point number, and the sliding operation is invalid.
In this embodiment, when the number of the preset touch points is set, whether the number of the touch points in the finger sliding data is consistent with the number of the preset touch points is detected in real time, so as to determine whether the user performs effective sliding.
Further, in another embodiment of the present application, the step S201 may include: detecting touch points of a user on an annular touch screen of the terminal to obtain the number of the touch points; recording the initial position of the touch point in the sliding operation to obtain the coordinate of the touch point; and determining the number of touch points and the coordinates of the touch points as finger sliding data.
Specifically, the number of touch points may not be limited before the slide operation. The user can freely determine the number of touch points and slide on the surface of the annular touch screen. The method comprises the following steps that an annular touch screen automatically detects touch points generated by finger contact of a user to obtain the number of the touch points; and for each touch point, recording the coordinates of the touch point in real time to obtain the initial position of the touch point in the sliding operation and obtain the coordinates of the touch point. The number of touch points and the coordinates of the touch points form finger sliding data.
In this embodiment, the number of touch points may not be limited, and the number of touch points and the coordinates of the touch points of the user in the sliding operation may be automatically detected to obtain the finger sliding data.
Further, in another embodiment of the present application, the step S202 may include: determining a sliding distance calculation mode and a sliding angle calculation mode according to the number of the touch points; calculating the coordinates of the touch points according to a sliding distance calculation mode and a sliding angle calculation mode to obtain a sliding angle; first event information is determined based on the slip angle.
Specifically, when the number of fingers contacting the annular touch screen is different, there is a difference in the habitual rotation angle due to the limited size of the annular touch screen, and generally, the larger the number of fingers used, the smaller the rotation angle is generally. Therefore, the touch control algorithm in the present application is related to the number of touch points. The touch control algorithm relates to a sliding distance calculation mode and a sliding angle calculation mode, and determines a required sliding distance calculation mode and a required sliding angle calculation mode according to the number of touch points. Then calculating the coordinates of the touch points according to a sliding distance calculation mode to obtain an average sliding distance; and calculating the average sliding distance according to a sliding angle calculation mode to obtain a sliding angle. Under different touch point numbers, the standard sliding angle required for switching the options once is different, wherein the standard sliding angle is the angle required for rotating when the previous option is switched to the next option; and determining the option to which the sliding operation of the user is switched according to the calculated sliding angle, namely obtaining the first event information corresponding to the sliding operation.
Generally, according to the habit of holding a human body, a user needs at least two fingers to hold the circular touch screen, and uses at most four fingers, so that at most four touch points are generated, and the four touch points are sequentially a, B, C, and D, and then the coordinates of the touch points are as follows:
A0Y the initial Y coordinate of touch point a,
A1Y: the final Y coordinate of touch point A;
B0Y the initial Y coordinate of touch point B,
B1Y: the final Y coordinate of touch point B;
C0Y the initial Y coordinate of touch point C,
C1Y: the final Y coordinate of touch point C;
D0Y the initial Y coordinate of touch point D,
D1Y: the final Y coordinate of touch point D;
r: the radius of the novel knob is large;
α: the angle of rotation.
1) Two-point touch control algorithm:
two-point average sliding distance d = (A1Y-A0Y + B1Y-B0Y)/2
Sliding angle α = d × 360/2 π r = (A1Y-A0Y + B1Y-B0Y) × 360/4 π r
2) Three-point touch control algorithm:
three-point average sliding distance d = (A1Y-A0Y + B1Y-B0Y + C1Y-C0Y)/3
Sliding angle α = d × 360/2 π r = (A1Y-A0Y + B1Y-B0Y + C1Y-C0Y)
*360/6πr
3) The four-point touch control algorithm comprises the following steps:
four-point average sliding distance D = (A1Y-A0Y + B1Y-B0Y + C1Y-C0Y + D1Y-D0Y)/4
Sliding angle α = d × 360/2 π r =
(A1Y-A0Y+B1Y-B0Y+C1Y-C0Y+D1Y-D0Y))*360/8πr。
The speed of switching the options can be controlled through the number of the touch points; different standard sliding angles can be set according to the number of options, for example, when the number of touch points is two, a switching event is triggered every time 20 degrees is increased or reduced, and when the number of touch points is three, a switching event is triggered every time 15 degrees is increased or reduced; when the number of touch points is four, a switching event is triggered every 10 ° increment or decrement. In one embodiment, the standard sliding angle may be set to a degree interval, i.e. the angle required for a switching event is determined to be within a certain range, e.g. when the number of touch points is two, a rotation of 20-25 ° completes one switching event.
In this embodiment, a sliding distance calculation mode and a sliding angle calculation mode are determined according to the number of the touch points, and then coordinates of the touch points are calculated according to the sliding distance calculation mode and the sliding angle calculation mode to obtain first event information, so that switching of options is completed according to a sliding operation.
Further, the step S204 may include: detecting the pressing operation of a user on the annular touch screen to obtain finger pressing data, wherein the finger pressing data comprises pressing strength, pressing time and the number of pressing points; and determining second event information corresponding to the first event information according to the finger pressing data.
Specifically, the user may further edit, select, confirm, or exit the first event information by a pressing operation. The annular touch screen can be pressed through the finger to the user, and pressure sensor carries out data acquisition to pressing operation and obtains the finger and press data, and the finger is pressed data and is included according to pressure degree, press time and press point quantity.
The pressing force degree can be the force of the user pressing the annular touch screen; the press time may be a length of time that the user presses the annular touch screen; the number of pressed points may be the number of fingers used by the user when pressing the annular touch screen. According to the finger pressing data, the operation executed by the user on the first event information can be further determined to obtain second event information, for example, the first event information is the option of switching to the picture color by the user, then the determination event is triggered by the pressing operation, and then the terminal displays the options below the picture color so that the user can select and edit the options; or, the user triggers an exit event by pressing operation, and the terminal exits from the current page and enters into a page at the upper level (for example, the page at the upper level may include options of image display and sound playing); or the user switches to the heating time event through the sliding operation, the user can perform timing through the pressing operation, and the heating time is in direct proportion to the pressing time of the user, so that the heating time is edited and determined.
The degree of compression, the time of compression, and the number of compression points may all affect the determination of the second event information. In one embodiment, after determining the first event information, the terminal may further play a press prompt message through a display screen or a player, so as to indicate a press operation of the user.
In one embodiment, when the user performs terminal control through the annular touch screen, the sliding operation and the pressing operation can be performed for multiple times. The user can realize the whole control of the terminal through the annular touch screen.
In the embodiment, the finger pressing data are obtained by collecting the pressing intensity, the pressing time and the number of pressing points when the user presses the annular touch screen, so that the second event information is determined according to the pressing data, the terminal is controlled by pressing, and the control mode of the terminal is enriched.
Further, the touch screen-based terminal control method may further include: and displaying candidate event information corresponding to the sliding operation/pressing operation through the terminal.
Specifically, when the user performs a sliding operation or a pressing operation, the terminal may present the candidate event information in real time. For example, when a user performs a sliding operation, the event options corresponding to the sliding operation are displayed in real time; when the heating time is adjusted through the pressing operation, the heating time corresponding to the pressing operation is displayed in real time, so that the user can acquire the current event information in time, and the terminal can be controlled conveniently.
In this embodiment, candidate event information corresponding to the sliding operation/pressing operation is displayed through the terminal, so that a user can acquire current event information in time, and the terminal can be controlled conveniently.
