Moreover, although the terms first, second, …, etc. may be used herein to describe various elements, these terms are only used to distinguish one element or operation from another element or operation described by the same technical terms. Unless the context clearly dictates otherwise, the terms do not specifically refer or imply an order or sequence nor are they intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic view of a wearable device 100 according to an embodiment of the invention. The wearable device 100 includes a pointer 110, a touch panel 120 and a wristband 160, the wearable device 100 may be a smart watch with a physical metal pointer, and the touch panel 120 may be a capacitive touch panel. The wearable device 100 determines whether the wearable device 100 is touched according to the capacitance variation of the touch panel 120.
When the wearable device 100 is not used, the capacitance value of the touch panel 120 does not change, and therefore the wearable device 100 determines that there is no touch.
Since the capacitor is structurally composed of two metal plates or conductors on metal surfaces, when a finger of a user touches the touch panel 120, a new capacitor is formed between the finger and the touch panel 120 because a human body is a conductor, and the capacitor is a capacitance between the finger and the touch panel 120. The equivalent capacitance value at this time is the sum of the capacitance value of the touch panel 120 itself and the capacitance value between the finger and the touch panel 120, and the sum is greater than the capacitance value of the touch panel 120 itself, so the wearable device 100 determines the touch state and performs the touch operation.
In the case of the wearable device 100 having the pointer 110, since the pointer 110 is also a conductor, a new capacitance is formed between the pointer 110 and the touch panel 120, and the capacitance is a capacitance between the pointer 110 and the touch panel 120. Similarly, the equivalent capacitance at this time is the sum of the capacitance of the touch panel 120 itself and the capacitance between the pointer 110 and the touch panel 120, and the sum is greater than the capacitance of the touch panel 120 itself. In this case, when the user does not touch the touch panel 120 or does not use the wearable device 100, the wearable device 100 may determine that the touch state is the touch state and perform the touch operation, which may cause a misjudgment, and therefore, the capacitance determination method of the wearable device 100 needs to be corrected to avoid the misjudgment.
Referring to fig. 2, fig. 2 is a functional block diagram of a cross-section AA' of the wearable device 100 shown in fig. 1 according to an embodiment of the invention. The wearable device 100 includes a pointer 110, a touch panel 120, a display element 130, a processing circuit 140, a glass layer 150, and a watch band 160.
Referring to fig. 3A, fig. 3A is a schematic diagram of a pointer segment and a touch panel block according to an embodiment of the invention. The pointer 110 includes a pointer section 110a and a pointer section 110b, and the touch panel 120 includes a touch panel block 120a, a touch panel block 120b, and a touch panel block 120 c. For convenience of description, the pointer segment 110a, the pointer segment 110b, the touch panel block 120a, the touch panel block 120b and the touch panel block 120c are taken as examples for description, but the pointer and the touch panel of the present invention are not limited by this segmentation and partition method, and may have other design manners according to actual situations.
In this embodiment, the partitioning method of the touch panel area may be that the area of the touch panel area 120a is 1 time, and the area of the other areas is designed to be between 0.8 times and 1.2 times. For example, the touch panel area 120b is designed to be 1.2 times, and the touch panel area 120c is designed to be 0.8 times.
As described above, the judgment of the touch panel 120 overlapped with the pointer 110 needs to be corrected. The processing circuit 140 is configured to determine whether an equivalent capacitance value between one of all the pointer segments and one of all the touch panel blocks is greater than a reference capacitance value therebetween, and when the equivalent capacitance value is greater than the reference capacitance value, the processing circuit 140 is configured to perform a touch operation of the wearable device 100. The following description takes the pointer segment 110a, the pointer segment 110b, the touch panel block 120a, the touch panel block 120b, and the touch panel block 120c as examples.
When the user has not touched the touch panel block 120a of the touch panel 120, the touch panel block 120a overlaps the pointer segment 110a of the pointer 110, so the reference capacitance between the touch panel block 120a and the pointer segment 110a needs to be corrected to avoid the erroneous determination caused by the user not touching. In this case, the calibration method is to set the reference capacitance between the touch panel block 120a and the pointer segment 110a to be the equivalent capacitance between the pointer segment 110a and the touch panel block 120a, i.e. the capacitance of the touch panel 120 itself plus the capacitance between the pointer segment 110a and the touch panel block 120a, by the processing circuit 140.
At this time, since the equivalent capacitance between the touch panel block 120a and the pointer segment 110a is not greater than the reference capacitance between the touch panel block 120a and the pointer segment 110a, the processing circuit 140 determines that the touch panel block is not touched.
When the user touches the touch panel block 120a of the touch panel 120, since a new capacitance is formed between the finger and the touch panel block 120a, the equivalent capacitance between the pointer segment 110a and the touch panel block 120a plus the capacitance between the finger and the touch panel block 120a is greater than the set reference capacitance, so the processing circuit 140 determines that the touch operation of the wearable device 100 is performed by touch.
When the user has not touched the touch panel block 120b of the touch panel 120, the processing circuit 140 does not need to correct the reference capacitance of the touch panel block 120b and maintains the reference capacitance of the touch panel block 120b as the capacitance of the touch panel 120 itself because the touch panel block 120b and the pointer 110 are not overlapped.
At this time, since the equivalent capacitance of the touch panel block 120b is not greater than the reference capacitance of the touch panel block 120b, the processing circuit 140 determines that the touch panel is not touched.
When the user touches the touch panel block 120b of the touch panel 120, a new capacitance is formed between the finger and the touch panel block 120b, and the equivalent capacitance of the touch panel block 120b is greater than the reference capacitance of the touch panel block 120b, that is, the capacitance of the touch panel 120 itself plus the capacitance between the finger and the touch panel block 120b is greater than the capacitance of the touch panel 120 itself, so the processing circuit 140 determines that the user is touching and performs the touch operation of the wearable device 100.
When the user has not touched the touch panel block 120c of the touch panel 120, the touch panel block 120c overlaps the pointer segment 110b of the pointer 110, so that the reference capacitance value needs to be corrected to avoid the situation of erroneous determination caused by the user not touching. In this case, the calibration is performed by setting the reference capacitance between the touch panel block 120c and the pointer segment 110b to be the equivalent capacitance between the touch panel block 120c and the pointer segment 110b, i.e. the capacitance of the touch panel 120 itself plus the capacitance between the pointer segment 110b and the touch panel block 120c, by the processing circuit 140.
At this time, since the equivalent capacitance between the touch panel block 120c and the pointer segment 110b is not greater than the reference capacitance between the touch panel block 120c and the pointer segment 110b, the processing circuit 140 determines that the touch panel is not touched.
When the user touches the touch panel block 120c of the touch panel 120, since a new capacitance is formed between the finger and the touch panel block 120c, the equivalent capacitance between the pointer segment 110b and the touch panel block 120c plus the capacitance between the finger and the touch panel block 120c is greater than the set reference capacitance, so the processing circuit 140 determines that the touch operation of the wearable device 100 is performed.
In one embodiment, the pointer segment is segmented such that the pointer segment 110a is larger than the pointer segment 110b, and the touch panel block 120a, the touch panel block 120b and the touch panel block 120c are equal to each other. Therefore, the equivalent capacitance between the pointer segment 110a and the touch panel area 120a is greater than the equivalent capacitance between the pointer segment 110b and the touch panel area 120c, and the reference capacitance between the pointer segment 110a and the touch panel area 120a is greater than the reference capacitance between the pointer segment 110b and the touch panel area 120 c.
That is, the reference capacitance values between different panel blocks and different pointer segments are set according to the overlapping areas between the panel blocks and the pointer segments, and different reference capacitance values exist if the overlapping areas are different.
Referring to fig. 3B, fig. 3B is a schematic diagram of a pointer segment and a touch panel block according to an embodiment of the invention. The pointer 110 includes a pointer section 110c, a pointer section 110d, and a pointer section 110e, and the touch panel 120 includes a touch panel block 120d, a touch panel block 120e, and a touch panel block 120 f. For convenience of description, the pointer segment 110c, the pointer segment 110d, the touch panel block 120e, the touch panel block 120d, the touch panel block 120e and the touch panel block 120f are taken as examples for description, but the pointer and the touch panel of the present invention are not limited by this segmentation and partition method, and may have other design manners according to actual situations.
In this embodiment, the partitioning method of the touch panel area may be that the area of the touch panel area 120d is 1 time, and the area of the other areas is designed to be between 0.6 times and 1.2 times. For example, the touch panel area 120f is designed to be 1.2 times, and the touch panel area 120e is designed to be 0.6 times.
In this embodiment, the pointer section 110c, the pointer section 110d and the pointer section 110e can be designed to be equal to each other. As described above, the reference capacitance values between different panel blocks and different pointer segments are set according to the overlapping areas between the panel blocks and the pointer segments, so that the reference capacitance values of the touch panel block 120d, the touch panel block 120e and the touch panel block 120f overlapping with the pointer segment 110c, the pointer segment 110d and the pointer segment 110e can be set to be the same capacitance value. The details are as follows.
When the user has not touched the touch panel block 120d of the touch panel 120, the touch panel block 120d overlaps the pointer segment 110e of the pointer 110, so the reference capacitance value needs to be corrected to avoid the erroneous determination caused by the user not touching. In this case, the calibration method is to set the reference capacitance between the touch panel block 120d and the pointer segment 110e to be the equivalent capacitance between the touch panel block 120d and the pointer segment 110e, i.e. the capacitance of the touch panel 120 itself plus the capacitance between the pointer segment 110e and the touch panel block 120d, by the processing circuit 140.
Similarly, when the user has not touched the touch panel block 120e or the touch panel block 120f of the touch panel 120, since the pointer segment 110c, the pointer segment 110d and the pointer segment 110e are designed to be equal to each other, the processing circuit 140 sets the reference capacitance between the touch panel block 120e and the pointer segment 110c to the capacitance of the touch panel 120 itself plus the capacitance between the pointer segment 110c and the touch panel block 120e, and sets the reference capacitance between the touch panel block 120f and the pointer segment 110d to the capacitance of the touch panel 120 itself plus the capacitance between the pointer segment 110d and the touch panel block 120 f.
The capacitance between the pointer segment 110e and the touch panel block 120d, the capacitance between the pointer segment 110c and the touch panel block 120e, and the capacitance between the pointer segment 110d and the touch panel block 120f are equal, so the reference capacitance set by the three will also be equal.
When the user touches the touch panel block 120d of the touch panel 120, since a new capacitance is also formed between the finger and the touch panel block 120d, the equivalent capacitance between the pointer segment 110e and the touch panel block 120d plus the capacitance between the finger and the touch panel block 120d is greater than the set reference capacitance, so the processing circuit 140 determines that the touch operation of the wearable device 100 is performed by touch. The operations performed by the user when touching the touch panel block 120e and the touch panel block 120f of the touch panel 120 are the same, and are not described herein again.
Referring to fig. 4, fig. 4 is a flow chart of an operation method 200 according to an embodiment of the invention, and fig. 3A and 3B are referenced together for easy understanding of the operation method 200 shown in fig. 4. The operation method 200 includes steps S210, S220, and S230. In step S210, a reference capacitance value between one of the pointer segments and one of the touch panel segments is set by the processing circuit 140. In step S220, it is determined whether an equivalent capacitance between one of the plurality of pointer segments and one of the plurality of touch panel blocks is greater than a reference capacitance, if so, step S230 is executed, otherwise, step S210 is returned to. In step S230, a touch operation of the wearable device 100 is performed, such as activating a display screen or other functions that can be activated by the touch operation.
Referring to fig. 5, fig. 5 is a flow chart of an operating method 200a according to an embodiment of the invention. Step S210 in fig. 4 includes step S211, step S212, and step S213. In step S211, a first equivalent capacitance value between a first pointer section of the pointer sections and a first touch panel block of the touch panel blocks is set by the processing circuit 140. In this embodiment, the first pointer segment may be the pointer segment 110c, and the first touch panel block may be the touch panel block 120 e.
In step S212, a second equivalent capacitance value between a second pointer segment in the pointer segment and a second touch panel block in the touch panel blocks is set by the processing circuit 140. In this embodiment, the second pointer segment may be the pointer segment 110d, and the second touch panel block may be the touch panel block 120 f.
In step S213, a third equivalent capacitance value between a third pointer segment in the pointer segments and a third touch panel block in the touch panel blocks is set by the processing circuit 140. In this embodiment, the third pointer segment may be the pointer segment 110e, and the third touch panel block may be the touch panel block 120 d.
In summary, the wearable device sets different reference capacitance values for different touch panel blocks in the touch panel, so as to prevent the conductors other than the fingers from interfering with the touch operation on the touch panel, thereby improving the operation experience of the user and increasing the touch accuracy.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
