As shown in fig. 3, another embodiment of the present application provides a display method 02 of a virtual knob, including:
and S1, displaying the virtual knob on the display screen. The virtual knob comprises a plurality of option icons, and each option icon is displayed in a preset display position; the preset display position is preset.
For example, as shown in fig. 4, the virtual knob includes 7 option icons and other pattern icons (e.g., a circular pattern with an "OK" character), and the 7 option icons are "cake", "bread-fermented", "milk", "roast meat", "seafood", "rice", and "bread", respectively. The 7 option icons are arranged along a 60 arc to facilitate control accuracy and increase data capacity. The 7 option icons are arranged around a circular pattern with the word "OK".
The angle of the circular arc occupied by the 7 option icons is 60 degrees, namely the angle corresponding to the circular arc between two option icons at two ends is 60 degrees, and the angle of the circular arc between two adjacent option icons is 10 degrees.
Radius R of the circle on which the arc is located2The position (X, Y) of the center O of the circle in the entire display screen (X, Y are the horizontal and vertical coordinates of the center O, respectively, and the corresponding origin is the lower left corner vertex of the display screen). Setting a preset display position 2 with coordinates of (X-R)2Y) at the set preset display position 1 (X)1,Y1) When calculated according to a trigonometric function, a ═ R2*sinα；b＝R2Sin α, the position corresponding to "preset display position 1" is (X-R)2*cosα,Y+R2Sin α), wherein X, Y, R2All are fixed values and the other preset display positions are set according to the method, so that the preset display positions are only related to the angle (radian), and the change of each option icon is only related to the angle (radian). in the embodiment, α is equal to 10 °.
In some embodiments, step S1, displaying a virtual knob on the display screen, includes: setting an initial selected icon, and taking the initial selected icon as a selected icon when the display screen just starts to display the virtual button.
One of the option icons may be set as the initially selected icon, for example, the option icon of "meat roasting" is used as the initially selected icon, each time the display screen is turned on, the "meat roasting" option icon is displayed as the selected icon, that is, the "meat roasting" option icon is a default icon, and the "meat roasting" option icon is displayed as the initially selected icon no matter which gear or state the physical knob is currently in when the display screen is turned on.
The last displayed option icon when the display screen of the electrical appliance is used last time can be used as the initial selected icon, for example, when the electrical appliance is used last time, the last displayed selected icon is 'rice class', and when the electrical appliance is turned on next time, the 'rice class' option icon is used as the selected icon.
S2, acquiring a signal from the entity knob; the solid knob is electrically connected with the display screen.
When the solid knob is rotated, an electric signal is sent. The display screen acquires an electrical signal from the physical knob.
And S3, determining the alternative icon to be changed according to the signal from the entity knob.
And S4, replacing the display state of the existing selected icon with the normal display state, and replacing the display state of the candidate icon to be changed with the highlighted state to obtain a new selected icon.
The display states of the option icons comprise a highlighted state and a normal display state, the selected icons are the option icons displayed in the highlighted state, the alternative icons are the option icons displayed in the normal display state, and the alternative icons to be changed are the alternative icons in the display state to be changed.
For example, the highlight display state may be a large font display state, and the normal display state may be a small font display state; the "roast meat" is the selected icon, and the other option icons are alternative icons. In addition, the highlight display state may also be set to a high-luminance display state of display luminance different from that of the normal display state, or to appear a color different from that of the normal display state.
In certain embodiments, the method further comprises: s5, sequentially changing the corresponding display positions of the option icons according to the signals to finally display the newly selected icon at the appointed preset display position; the corresponding display position is a preset display position for correspondingly displaying one option icon.
For example, the preset display position where the "preset display position 2" is located is the designated preset display position. The designated preset display position is used for displaying the selected icon.
In certain embodiments, the method further comprises: and S6, in the process of sequentially changing the corresponding display positions of the option icons, hiding the option icons which are not provided with the new preset display positions and can be displayed according to the fact that one option icon is not provided with the new preset display positions and can be displayed.
For example, the option icons that do not have a new preset display location available for display may be faded out. For example, as shown in fig. 5, if the option icon is changed from the preset display position in the counterclockwise direction, the "bread class" option icon has no new preset display position to display, and the "bread class" option icon is faded out.
In certain embodiments, the method further comprises: and S7, drawing a new option icon at the vacated preset display position in the process of sequentially changing the corresponding display position of each option icon.
For example, as shown in FIG. 5, a new option icon may be faded in. For example, as shown in fig. 5, if the preset display position of the option icon is changed in the counterclockwise direction, the preset display position where the "cake type" option icon is originally located is vacated, and a new option icon, for example, a new "soup type" option icon shown in fig. 4, is drawn in a gradual manner at the vacated preset display position.
In some embodiments, the sequentially changing the corresponding display position of each option icon includes: s51, sequentially displaying the option icons in the passing positions for a period of time; the passing position is a position for displaying the option icon within a period of time in the process of changing the corresponding display position; and a plurality of passing positions are arranged between two adjacent preset display positions. The number of the passing positions can be set according to actual needs.
For example, if the arc portion between the preset display position where the "meat roasting" option icon is located and the preset display position where the "milk type" option icon is located is 10 °, four passing positions are provided in the arc portion between the two preset display positions, the 10 ° arc portion is divided into five parts, and each part corresponds to an arc of 2 °. When the direction of the selection item icon changing the preset display position is anticlockwise, the milk type selection item icon needs to be anticlockwise rotated by 10 degrees, and then the milk type selection item icon is sequentially displayed at the passing position according to equal time intervals and finally displayed at the preset display position.
For example, when the physical knob is a stepped knob, the virtual knob on the display screen is jumped instead of rolling, and is rotated to a corresponding direction by a scale value after receiving a physical knob gear change signal, the image is drawn and then the feeling of the human is instantly achieved, in order to have the rolling feeling, a delay effect of 100ms is set, the angle Q value is slowly changed by an interval angle D/(N-1) within 100ms, the forward rotation and the reverse rotation are only the problems of addition and subtraction, and the virtual button image is redrawn every 20ms, so that the continuous rolling effect is achieved. Equivalently, 5 passing positions are arranged between two adjacent preset display positions, the option icon is displayed at each passing position for 20ms, and therefore the visual effect of rolling the option icon when the corresponding display position is changed is achieved.
For example, the rotation angle of the stepless knob is calculated according to pulses, the signal transmitted every time the stepless knob rotates by 1 ° includes C pulses, in the present embodiment, the distance between every two adjacent preset display positions is 10 °, and when the virtual knob receives 10C pulses, the display state of the existing selected icon is changed to the normal display state, and the display state of the candidate icon to be changed is changed to the highlighted state, so that a new selected icon is obtained. Thus, the visual effect of the virtual knob motion is also 'jumping', and in order to enable the visual effect of the virtual knob motion to be 'rolling', a plurality of passing positions are set between two adjacent preset display positions. And setting the virtual knob to change the position displayed once when the virtual knob acquires one pulse, so that the visual effect is 'rolling', 10C pulses need to be changed for 10C times, and the number of a plurality of passing positions set between two adjacent preset display positions is 10C-1. The number of times of redrawing the virtual button is determined according to the actual situation, generally, the redrawing frequency is above 50hz to have a smooth dynamic display effect, i.e. to ensure that the redrawing is performed once within 20ms or 20 ms.
When the number of pulses sent by the stepless knob continuously rotating once reaches a preset threshold value (for example, the number can be set to 5C), the option icon finishes the replacement of the preset display position, namely the preset display position is replaced to the adjacent preset display position for display; if the number of pulses sent by the stepless knob continuously rotating once does not reach the preset threshold value, the option icon returns to the original preset display position for display; in the process that the option icons return to the original preset display position for display, the option icons can sequentially pass through the passing positions and are displayed on the passing positions, a certain time is displayed on each passing position, and finally the option icons return to the original preset display position for display. For example, in the process of returning the option icon to the original preset display position, the option icon is displayed at each passing position for 20ms, so that the visual effect of rolling the option icon when returning to the original preset display position is achieved.
In some embodiments, S3, determining, according to the signal, an alternative icon to be changed includes:
s31, decoding the signal to obtain the rotation direction mark information carried in the signal; for example, a clockwise direction of rotation or a counterclockwise direction of rotation;
and S32, according to the rotation direction mark information, selecting an alternative icon corresponding to the direction mark information from alternative icons adjacent to the selected icon as a candidate icon to be changed.
For example, the virtual knob may be rotated in the same direction as the physical knob, or the virtual knob and the physical knob may be rotated in opposite directions. In the virtual knob, when the information carried by the signal indicates a counterclockwise rotation direction, selecting an adjacent alternative icon corresponding to the selected icon in the counterclockwise rotation direction as an alternative icon to be changed; in the figure, adjacent option icons of the 'meat roasting' option icon are a 'milk' option icon and a 'seafood' option icon; in the anticlockwise rotation direction, the alternative icon to be changed of the meat roasting option icon is milk; in the clockwise rotation direction, the to-be-changed alternative icon of the "meat-roasting" option icon is "seafood".
In some embodiments, the solid knob is a stepped knob.
In some embodiments, an angle between two adjacent gear positions of the stepped knob is equal to an angle between two adjacent option icons.
In some embodiments, the solid knob is a stepless knob.
In some embodiments, the option icons may be arranged in other ways besides circular arcs, for example, along a straight line, or along an irregular curve.
In some embodiments, the step-switching process for smoothing the display of the virtual knob comprises: sequentially displaying the option icons in a passing position for a period of time; the passing position is a position for displaying the option icons within a period of time in the process of sequentially moving each option icon along the rotating direction by the angle to reach the next preset display position; and a plurality of passing positions are arranged between two adjacent preset display positions.
Another embodiment of the present application provides a linkage display method 03 of a virtual knob. A virtual button is presented on the display screen, as shown in fig. 4 and 5, the virtual knob includes 7 option icons, and the 7 option icons are respectively "cake type", "bread type-fermentation", "milk type", "roast meat", "seafood type", "rice type" and "bread type". In the linkage display process with the entity knob, the operation of the entity knob is synchronously performed, so that ideal use experience is achieved. The physical knob can be arranged above the front surface of the display screen or outside the display screen. The 7 option icons are arranged along a circular arc to facilitate control accuracy and increase data capacity.
The angle of the circular arc occupied by the 7 option icons is 60 degrees, namely the angle corresponding to the circular arc between two option icons at two ends is 60 degrees, and the angle of the circular arc between two adjacent option icons is 10 degrees.
Type selection of the solid knob: currently, the mainstream knobs are classified into two types, one type is a stepped knob, namely, the knob rotates for a circle and has limited gears, and the gears are jammed in the rotating process, and the other type is a stepless knob, and the knob represents the rotating angle in a pulse mode.
The condition of the stepped knob needs to be calculated according to the display effect of the content of the display screen, N stages are needed in the included angle from the first data and the last data in all displayed N (7 in fig. 4 and 5) data to the circle center of the knob in the graph, and if the included angle from the first data and the last data to the circle center of the knob is D degrees, the whole circle needs (360 degrees/D degrees) N stages.
The stepless knob needs to calculate the pulse number of the knob angle, assuming that 1 ° is C pulses, N data have (N-1) intervals, the angle D ° needs D × C pulses, each interval occupies an angle D/(N-1), and the required pulse number is D × C/(N-1), i.e., each gear position D × C/(N-1) pulses.
The virtual knob is realized: as shown in FIG. 6, the outer edge of the knob has a radius R1,Then radius R of the virtual knob2It is desirable to be greater than R1Position of virtual knob center O in whole display screen [ X, Y](X, Y are the coordinates of the knob circle in the horizontal and vertical directions respectively, the corresponding origin is the lower left corner of the display screen), and the calculation is carried out according to a trigonometric function, X1＝R2*sinα；Y1＝R2Sin α, the position corresponding to "character 1" is [ X-R2*sinα,Y+R2*sinα]Wherein X, Y, R2The values are fixed, so that the position of the character is only related to the angle (radian), and the change of the virtual knob is only related to the angle (radian).
As shown in fig. 7, in another embodiment, the physical knob has M data amounts (i.e., M shift positions, where M is an odd number), wherein the middle of the M data corresponding to the preset display position "preset display position 2" at the center of the virtual knob has (M-1)/2 data at the upper and lower sides, and the number of intervals is ((M-1)/2-1). If the angle at the "preset display position 2" is default 0, the angle range is [ - ((M-1)/2-1) × (D/(N-1)) ], the angle of each piece of data can be calculated as shown in fig. 7, but not all data are displayed in the display screen, only data in the above-mentioned D ° range are displayed, a current angle value Q is required to identify the current position of the selected icon, and data in the angle [ Q-D/2, Q + D/2] can be displayed. Then, the control of the solid knob is associated with the current angle Q value of the selected icon, and from the analysis, the whole virtual button image is redrawn by an interval angle D/(N-1) every time the knob is rotated by one step under the condition of the step knob; the stepless knob is calculated according to the pulses, and the Q value changes (1/C) after receiving one pulse every 1 ℃ when C pulses are needed, and then the virtual button image is redrawn. Regardless of the stepped knob and the stepless knob, the influence of the forward and reverse rotation on the Q value directivity needs to be followed, and the Q value increases when the knob is rotated clockwise and decreases when the knob is rotated counterclockwise. So far, the knob and the virtual knob on the display screen are linked.
If M is an even number, the M/2 th data or the M/2+1 th data corresponds to the preset display position 'preset display position 2' in the middle of the virtual knob, and M/2-1 data and M/2 data are respectively arranged on two sides of the M/2 th data. The angle at "preset display position 2" is 0 by default. The specific corresponding relation can be adjusted according to actual needs.
In some embodiments, when the knob selects the step knob, the virtual knob on the screen is jumped instead of scrolling, and is rotated to a corresponding direction by a scale value after receiving a knob gear change signal, the image is drawn and then the feeling of the virtual knob is instantly achieved, in order to have the scrolling feeling, a 100ms delay effect is set, the angle Q value is slowly changed by an interval angle D/(N-1) within 100ms, the forward rotation and the reverse rotation are only the problem of addition and subtraction, and the virtual knob image is redrawn every 20ms, so that the continuous scrolling effect is achieved.
When the knob selects the stepless knob, under the condition that the angle Q value is processed according to the pulse number and the virtual button image is redrawn, the condition that the angle Q value is not the same as the angle value corresponding to the data content when the knob stops exists, in this condition, the angle Q value needs to be corrected, when the knob stops, namely under the condition that the pulse signal is not received again, the Q value needs to be corrected to the angle value of the data content with the nearest absolute difference, and the image needs to be changed slowly and updated, wherein the rolling effect similar to the stepped knob is not repeated.
The virtual knob of the display screen is effectively associated with the actual knob, the problem that only one circle of gears of the traditional knob can be selected is solved, the technology theoretically supports data gears of unlimited size, and the functions of the traditional knob are greatly expanded.
The precision control is accurate, the angle of the selected gear can be determined according to the type selection of the knob, the radius range can be adjusted in a large range, and the control precision is improved.
The solid knob can be arranged on the right side of the display screen, other multi-direction combination modes can also be adopted, and the relative position of the solid knob and the display screen can be in various modes such as up-down mode, down-up mode, left-right mode and the like. The virtual knob is realized on the display screen, and the display screen can be various display screens such as an embedded display screen, an industrial personal computer and an android system display screen. The display screen and the entity knob for realizing the method can be applied to various electric appliances such as microwave ovens, ovens and the like.
