Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiments of the present invention, it should be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.
Example one
An embodiment of the present invention provides a touch method, which is applied to a watch, and as shown in fig. 1, the watch includes a touch layer 4 and a pointer 2, and as shown in fig. 2, the touch layer includes a plurality of electrode blocks 10, the pointer is a conductor, and the pointer includes at least one pointer.
The hand may include only one of a second hand, a minute hand and an hour hand; alternatively, the hands may include two of a second hand, a minute hand and an hour hand, such as a minute hand and an hour hand, a minute hand and a second hand, a second hand and an hour hand; alternatively, the hands may include a second hand, a minute hand and an hour hand, and may be customized according to the user's requirements.
The material of the pointer is not limited, and the pointer can be a metal pointer, or can be other pointers capable of influencing the capacitance value of the electrode block, and can be selected according to actual conditions.
The touch layer can adopt a self-contained touch mode, and at the moment, the touch layer is of a layer structure; a mutual capacitance touch manner may also be adopted, and at this time, the touch layer is a multilayer structure. The embodiment of the invention takes a self-contained touch manner as a touch layer and a layer structure as an example for explanation. The plurality of electrode blocks may be arranged in multiple rings or in a square shape, which is not limited herein. Here, the touch layer shown in fig. 2 is described by taking an example in which the touch layer includes a plurality of electrode blocks 10 arranged in a three-ring shape. Fig. 2 illustrates a watch with a diameter of about 1.2 inches, and a touch layer including 28 electrode blocks.
The watch can be an intelligent watch, and the intelligent watch has information processing capacity and accords with the basic technical requirements of watches. Besides indicating time, the smart watch may also have one or more functions of reminding, navigation, calibration, monitoring, interaction, and the like.
Referring to fig. 3, the method includes:
and S11, storing the capacitance compensation values of the electrode blocks corresponding to the pointer at all times in a non-touch state.
The above-mentioned non-touch state means: no finger, capacitive pen, etc. touches the touchable area of the watch. In this state, the capacitance change of the electrode block of the touch layer is derived from the pointer.
And S12, acquiring the current time pointed by the pointer.
And S13, acquiring a first capacitance compensation value according to the current moment, wherein the first capacitance compensation value is the capacitance compensation value of the electrode block corresponding to the pointer at the current moment in a non-touch state.
And S14, acquiring the touch capacitance value variable quantities of all the electrode blocks at the current moment in the touch state.
The touch state is: there is a state where a finger, a capacitance pen, or the like touches the touchable area of the watch. In this state, in addition to the pointer, the capacitance of the electrode block of the touch layer is greatly affected by a finger, a capacitance pen, and the like.
And S15, compensating the touch control capacitance value variation of the electrode block corresponding to the pointer at the current moment in the touch control state according to the first capacitance value compensation value, and obtaining the compensated capacitance value variation of all the electrode blocks compensated at the current moment.
The specific compensation method is not limited herein. For example, if the first capacitance compensation value is obtained by taking a negative value for the capacitance variation of the electrode block corresponding to the pointer at the current time in the non-touch state, the compensation method may adopt a method of directly adding the first capacitance compensation value and the touch capacitance variation of the electrode block corresponding to the pointer at the current time, so as to obtain the compensated capacitance variation of all the electrode blocks compensated at the current time.
The number of the numerical values included in the first capacitance compensation value is not limited, and is specifically determined according to the number of the electrode blocks corresponding to the current time pointer. The compensation capacitance value variation is divided into two types according to the corresponding relation between the electrode block and the pointer: one type is an electrode block corresponding to the pointer, and the compensation capacity value of the electrode block needs to adopt a first capacity value compensation value to compensate the touch control capacity value variation at the current moment in the touch control state; one type is an electrode block which does not correspond to the pointer, the compensation capacity value of the electrode block does not need additional compensation, and the compensated capacity value variation is the touch control capacity value variation at the current moment in the touch control state.
For example, referring to fig. 2, in a non-touch state, the electrode blocks corresponding to the second hand 11 at the current time are 1, 6, and 15, the capacitance value variations of the electrode blocks 1, 6, and 15 at this time are C1, C6, and C15, respectively, and negative values are taken to obtain the capacitance value compensation values of the electrode blocks 1, 6, and 15 at the current time as-C1, -C6, and-C15, respectively, and then the first capacitance value compensation value at the current time is-C1, -C6, and-C15. If the touch capacity value variation amounts of the electrode blocks 1, 6 and 15 corresponding to the current time pointer in the touch state are respectively C1 ', C6' and C15 ', then C1' -C1, C6 '-C6 and C15' -C15 are respectively the compensated capacity value variation amounts of the electrode blocks 1, 6 and 15; the residual electrode blocks except the electrode blocks 1, 6 and 15 do not need additional compensation due to no interference of the pointer, and the capacitance value variation after compensation is the touch capacitance value variation at the current moment in the touch state.
And S16, judging whether the compensated content value variation meets the touch response condition.
The touch response condition is not limited herein, and may be determined according to the actual situation.
And S17, if yes, feeding back the coordinates of the touch point. Here, the touch point coordinates are coordinates of the touch point.
The embodiment of the invention provides a touch method. In the method, the capacitance compensation value of the electrode block corresponding to the pointer at the current moment in the non-touch state is compensated for the touch capacitance variation of the electrode block corresponding to the pointer at the current moment in the touch state, so that the influence of the pointer on the electrode block can be eliminated, and the full-screen touch point coordinate reporting can be realized in the normal rotation state of the pointer; meanwhile, the error touch operation caused by the pointer can be avoided, so that the customer experience is improved, and the product quality is improved.
After determining whether the compensated content value variation satisfies the touch response condition at S16, if the compensated content value variation does not satisfy the touch response condition, indicating that no touch operation has occurred, the touch point coordinates do not need to be fed back.
Before storing the capacitance compensation values of the electrode blocks corresponding to the pointer at all times in the non-touch state at S11, the method further includes:
and S10, calculating the capacitance compensation value of the electrode block corresponding to the pointer at all times in the non-touch state.
Optionally, S10, calculating the capacitance compensation value of the electrode block corresponding to the pointer at all times in the non-touch state includes:
s101, acquiring position information of the pointer at all times.
The method for establishing the location information is not limited herein. For example, referring to fig. 4, a coordinate system is established with the center of the watch dial as the origin O, the horizontal right direction as the X-axis forward direction, and the vertical upward direction as the Y-axis forward direction. The length of the pointer is L1, the angle of the pointer when the pointer is overlapped with the X axis in the positive direction is zero degree, the pointer rotates clockwise generally, when the pointer rotates by the angle theta, the coordinate value corresponding to the end of the pointer is (L1cos theta, -L1sin theta), and the position range of the pointer is (0,0) to (L1cos theta, -L1sin theta). The coordinate range where the pointer is located is position information. In fig. 4, the rotation angle θ is smaller than 90 °. This is merely an example for explanation. When the rotation angle θ is other angles, the coordinate range can be determined by referring to the above method.
And S102, calculating the capacity value variation of the electrode block corresponding to the pointer at all times in the non-touch state according to the position information.
Here, the specific method for calculating the capacitance variation of the electrode block corresponding to the pointer at all times in the non-touch state according to the position information is not limited. For example, the volume value variation of the corresponding electrode block in the coordinate range can be calculated according to the coordinate range of the pointer at the current moment.
S103, taking a negative value for the capacitance value variation of the electrode block corresponding to the pointer at all times in the non-touch state, and obtaining the capacitance value compensation value of the electrode block corresponding to the pointer at all times in the non-touch state.
As an example, the method of calculating the capacitance compensation value is exemplified by the above-described hand for the second hand. Typically, the dial is provided with 60 scales at equal intervals, and the second hand is typically rotated at a frequency of one scale interval per second. The scale pitch refers to the distance between two scales. And calculating the capacitance compensation value of the electrode block corresponding to the second hand when the electrode block is respectively opposite to the 60 scales. Referring to fig. 2, at this time, the position of the second hand 11 affects the electrode blocks 1, 6, and 15, at the current time, the electrode blocks corresponding to the second hand are 1, 6, and 15, the capacitance values of the electrode blocks 1, 6, and 15 at this time are respectively calculated, the capacitance value variation caused by the second hand is C1, C6, and C15, and then the capacitance value variation is set to be a negative value, and the capacitance value compensation values of the electrode blocks 1, 6, and 15 at this time are-C1, -C6, -C15, respectively. The minute hand and the hour hand can acquire the capacity value compensation value in a similar manner.
The calculation method of the capacitance compensation value is simple and easy to realize. It should be noted that, theoretically, each time corresponds to a set of capacity compensation values. In practical application, the number of sets of capacitance compensation values can be reduced according to the touch precision requirement of a product and the design condition of an electrode block pattern (pattern).
Optionally, according to the usage habit of the user, the pointer may include: second hand, minute hand and hour hand.
S11, storing the capacitance compensation values of the electrode blocks corresponding to the pointer at all times in the non-touch state includes:
and respectively storing the capacitance compensation values of the electrode blocks corresponding to the second hand, the minute hand and the hour hand at all times in a non-touch state.
S13, obtaining the first capacitance compensation value according to the current time includes:
and respectively obtaining the capacitance value compensation values of the electrode blocks corresponding to the second hand, the minute hand and the hour hand at the current moment in a non-touch state according to the current moment.
S15, compensating the touch capacitance variation of the electrode block corresponding to the pointer at the current time in the touch state according to the first capacitance compensation value, and obtaining the compensated capacitance variation of all the electrode blocks compensated at the current time includes:
and respectively compensating the touch capacitance value variation of the electrode blocks corresponding to the second hand, the minute hand and the hour hand at the current moment in the touch state according to the capacitance value compensation values of the electrode blocks corresponding to the second hand, the minute hand and the hour hand at the current moment in the non-touch state, and obtaining the compensated capacitance value variation of all the electrode blocks compensated at the current moment.
When the second hand, the minute hand and the hour hand exist simultaneously, the influence of the second hand, the minute hand and the hour hand on the respective corresponding electrode blocks needs to be compensated respectively.
Optionally, the step S16 of determining whether the compensated content value variation satisfies the touch response condition includes:
and judging whether the compensated capacitance value variation is within the touch capacitance value threshold range. The touch tolerance threshold may be determined according to the touch precision requirement of the product, and is not specifically limited herein.

and executing a control program associated with the coordinates of the touch points, wherein the control program can be used for answering a call, monitoring a heart rate, navigating, reminding and the like.
