Description

Technical Field

[0001] The present invention relates to the field of touch recognition, and in particular to a touch control method, device and handheld appliance. Background Art

[0002] Touch control uses a touch sensor to detect user operations, and determines the corresponding control instructions based on the user's operations so that the device performs the corresponding operations. The advantage of touch control is that it eliminates the key structure, making the control area smoother and cleaner, which is conducive to improving the sealing and aesthetics of the structure surface. At the same time, this operation method does not require any external design, and is easy to operate and has a good experience.

[0003] According to the number of touch points, touch operations are mainly divided into touch screen mode and touch point mode. In the touch screen mode, the entire screen can detect the user's touch operation, which is very convenient to implement. However, in some scenarios, it is not necessary to set an operation screen. In this case, several touch points can be set to detect user operations.

[0004] The touch point method reduces the area of ​​the touch area or the number of detection points, reduces costs, has the advantages of general touch operations, and does not require a separate screen. It is widely used in some small appliances. However, due to the small area of ​​the touch area or the small number of detection points, it is difficult to achieve accurate correspondence between operations and instructions, and the richness of instructions is limited. Summary of the invention

[0007] In one embodiment, the present invention provides a touch control device, the touch control device comprising a wake-up monitoring module, a touch monitoring module and a processing module; The wake-up monitoring module is connected to the processing module and is used to monitor the user's wake-up operation; The touch monitoring module is connected to the processing module and is used to monitor the user's touch operation. The touch monitoring module includes a first touch area and a second touch area. The first touch area and the second touch area are arranged side by side or nested to form a whole.

DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0012] It is understood that the terms "first", "second", etc. used in the present invention may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script without departing from the scope of the present invention.

[0013] like Figure 1 , Figure 2 As shown, in one embodiment, a touch control method is proposed, which may specifically include the following steps: S101, monitoring whether a wake-up signal is received, and if so, enabling touch monitoring; S102, monitoring the first touch area to determine whether the first touch area generates a first valid signal; S103, if the first touch area generates a first valid signal, the first touch area and the second touch area are monitored simultaneously, and it is determined whether a second valid signal is generated according to the states of the first touch area and the second touch area; S104, if the second valid signal is generated, monitoring the second touch area to determine whether the second touch area generates a third valid signal; S105, if the third valid signal is generated, the corresponding instruction is determined and executed according to the first valid signal, the second valid signal and the third valid signal.

[0014] In this embodiment, awakening means that the device enters an operable waiting state from a sleep or standby state. The main differences between the previous and the next changes include but are not limited to the increase in the detection frequency of the touch module. In the sleep or standby state, the detection frequency is lower than the detection frequency in the waiting state, which can reduce power consumption. In the sleep or standby state, the first touch area and the second touch area are not monitored, so no effective signal will be generated when the first touch area and the second touch area are touched. There can be multiple sources of the wake-up signal. For example, a gyroscope is used to detect the acceleration or angle orientation of the device to determine whether the device is picked up. If the device is picked up, a wake-up signal is generated; a capacitive sensor is used to detect whether the holding part of the device is held to control the state of the device. Specifically, when the capacitance value is detected to reach the set range, it is determined that the device is held by a human hand, and a wake-up signal is generated at this time.

[0015] In this embodiment, enabling touch monitoring refers to starting monitoring of the first touch area and the second touch area.

[0016] In this embodiment, the first touch area is a contact area of ​​the capacitive sensor, and the second touch area is also a contact area of ​​the capacitive sensor. The first touch area and the second touch area are different in shape. The part of the first touch area that contacts the second touch area is a protrusion, and the part of the second touch area that contacts the first touch area is an inner concave part that matches the protrusion. The protrusion and the inner concave part are nested and connected, so that the first touch area and the second touch area are nested and arranged to form a whole. Figure 4 shown.

[0017] In this embodiment, the first valid signal is generated on the premise that the first touch area is touched, and the first valid signal is generated only when it is touched. The second valid signal is generated on the premise that the first touch area and the second touch area are touched at the same time. The third valid signal is generated on the premise that the second touch area is touched.

[0018] A touch control method provided by an embodiment of the present invention enables touch monitoring after receiving a wake-up signal; monitors the first touch area to determine whether the first touch area generates a first valid signal; if the first touch area generates a first valid signal, monitors the first touch area and the second touch area at the same time, and determines whether a second valid signal is generated according to the states of the first touch area and the second touch area; if a second valid signal is generated, monitors the second touch area to determine whether the second touch area generates a third valid signal; if a third valid signal is generated, determines and executes the corresponding instruction according to the first valid signal, the second valid signal, and the third valid signal. In this way, by monitoring the touch states of the first touch area and the second touch area to determine whether the first valid signal, the second valid signal, and the third valid signal are generated in sequence, and then the corresponding instruction is determined according to the first valid signal, the second valid signal, and the third valid signal, the accurate correspondence between the operation and the instruction is achieved, and the generation order of the first valid signal, the second valid signal, and the third valid signal corresponds to different instructions, which increases the richness of the instructions.

[0019] In one embodiment, before determining whether the second valid signal is generated, the method further includes: Determine whether the time from the production of the first valid signal exceeds the first preset time length. If it exceeds the first preset time length, clear the first valid signal. Otherwise, determine whether to generate a second valid signal.

[0020] In this embodiment, the first preset time length can be set to 300 ms.

[0021] In this embodiment, when the first preset time period is exceeded, the first valid signal is cleared, and at this time, whether the second valid signal is generated is no longer determined, but the process returns to the step of monitoring the first touch area to determine whether the first touch area generates the first valid signal.

[0022] In one embodiment, before determining whether the second touch area generates the third valid signal, the method further includes: Determine whether the time from the production of the second valid signal exceeds the second preset time length. If it exceeds the second preset time length, clear the first valid signal and / or the second valid signal. Otherwise, determine whether to generate a third valid signal.

[0023] In this embodiment, the second preset time length can be set to 300 ms.

[0024] In this embodiment, when the second preset time period is exceeded, the first valid signal and / or the second valid signal is cleared, and at this time, it is no longer determined whether the third valid signal is generated. Instead, the process returns to monitoring the first touch area to determine whether the first touch area generates the first valid signal.

[0025] In one embodiment, determining whether the first touch area generates a first valid signal includes: Obtaining the detection value of the first touch area and the current value of the second touch area; Calculating an absolute value of a difference between a detection value of the first touch area and a current value of the second touch area; It is determined whether the obtained absolute value reaches a first set threshold value, and if so, the first touch area generates a first valid signal.

[0026] In this embodiment, the first touch area and the second touch area are capacitive sensors, and the capacitance value is affected by the ambient temperature and humidity. When the environment changes, the sampled capacitance value will also change. Therefore, it is not possible to directly judge whether the first touch area or the second touch area is triggered and then judge whether the corresponding valid signal is generated based on the change of the capacitance of the first touch area or the second touch area. However, since the first touch area and the second touch area are affected by the environment in the same way, the capacitance value increases or decreases at the same time, so whether the first touch area or the second touch area is triggered can be judged by whether the difference between the first touch area and the second touch area changes. For example, the capacitance value of the first touch area at the initial temperature is a, and the capacitance value of the second touch area at the initial temperature is b. The absolute value of the difference between the capacitance values ​​of the two is c. No matter how the temperature changes, the absolute value of the difference between the capacitance values ​​of the two is always c. If the first touch area is triggered at this time, the capacitance value of the first touch area will change greatly. At this time, the absolute value of the difference between the capacitance values ​​of the two is not c, so this point can be used to judge whether the first touch area generates the first valid signal.

[0027] In this embodiment, the absolute value A of the capacitance difference between the first touch zone being triggered and not triggered at any temperature is determined, and the first set threshold value can be set to a value slightly smaller than the absolute value A of the capacitance difference.

[0028] In one embodiment, the step of determining whether to generate a second valid signal according to the states of the first touch area and the second touch area includes: Determining whether the first touch area and the second touch area are triggered at the same time; If yes, obtain the detection value of the first touch area and the detection value of the second touch area, and determine a reference value according to the detection value of the first touch area and the detection value of the second touch area; It is determined whether the obtained reference value reaches a second set threshold value, and if so, a second valid signal is generated.

[0029] In this embodiment, although the capacitance value of the capacitive sensor will change due to the influence of ambient temperature and humidity, the change is small and slow. For example, the humidity is different on rainy days and sunny days, so although the capacitance value on rainy days and sunny days is different, the capacitance value remains almost unchanged throughout the rainy day or sunny day. However, the change in capacitance value caused by triggering is huge and fast. At the moment of triggering, the capacitance value will change greatly. Therefore, to determine whether the first touch area or the second touch area is triggered, it is essentially to see whether the capacitance value changes greatly, and this change is easy to detect.

[0030] In this embodiment, only when the first touch area generates the first valid signal can it be determined whether the second valid signal is generated. The first touch area generating the first valid signal indicates that the first touch area is triggered, and the detection value of the first touch area has undergone a huge change. If the detection value remains unchanged after a huge change, it can be considered that the first touch area is continuously triggered, and at this time, it is only necessary to determine whether the second touch area is triggered. It should be noted here that the size and shape of the first touch area and the second touch area are inconsistent, so the initial value of the capacitance value is also different, and the changed capacitance value is not necessarily the same.

[0031] In this embodiment, the detection value of the first touch area and the detection value of the second touch area determine a reference value, determine the change value of the first touch area, determine the change value of the second touch area, and use the average of the two change values ​​as the reference value.

[0032] In this embodiment, the second set threshold value may be set to any value that is smaller than the first set threshold value and larger than half of the first set threshold value.

[0033] In one embodiment, the determining whether the second touch area generates a third valid signal; Obtaining the detection value of the second touch area and the current value of the first touch area; Calculating an absolute value of a difference between a detected value of the second touch area and a current value of the first touch area; It is determined whether the obtained absolute value reaches a third set threshold value, and if so, the second touch area generates a third valid signal.

[0034] In this embodiment, the absolute value B of the capacitance difference between the triggered and untriggered second touch zone at any temperature is determined, and the third set threshold can be set to a value slightly smaller than the absolute value B of the capacitance difference.

[0035] In this embodiment, only when the second valid signal is generated can it be determined whether the third valid signal is generated.

[0036] In this embodiment, it is not necessary to care whether the first valid signal will be generated, because the corresponding instruction can be determined only when the second valid signal is generated within the first preset time after the first valid signal is generated, and the third valid signal is generated within the second preset time after the second valid signal is generated. It is not necessary to care about the existence time of the valid signal or whether it appears repeatedly.

[0037] In one embodiment, the monitoring whether a wake-up signal is received, and if so, enabling touch monitoring, includes: monitoring whether a wake-up signal is received at a first frequency; If yes, touch monitoring is performed at the second frequency, otherwise touch monitoring is not performed; The second frequency is greater than the first frequency.

[0038] In this embodiment, the first frequency may be set to 40 Hz, that is, the step of monitoring whether the wake-up signal is received occurs once every 25 ms.

[0039] In this embodiment, the second frequency may be set to 1 kHz, that is, touch monitoring is performed once every 1 ms.

[0040] In one embodiment, determining the corresponding instruction according to the first valid signal, the second valid signal, and the third valid signal includes: The order in which the touch positions corresponding to the current first valid signal, the second valid signal, and the third valid signal are triggered is recorded as the first order; The order in which the touch positions corresponding to the previous first valid signal, the second valid signal, and the third valid signal are triggered is recorded as the second order; Determine whether the first sequence and the second sequence are the same, if they are the same, get the first corresponding instruction, otherwise get the second corresponding instruction; The first corresponding instruction and the second corresponding instruction are different instructions.

[0041] In this embodiment, the first valid signal is determined by the first touch area, the second valid signal is determined by the first touch area and the second touch area, and the third valid signal is determined by the second touch area. The first valid signal is generated first before the second valid signal is generated, and the third valid signal is generated. If for a total touch area, the first touch area is located on the left, the second touch area is located on the right, and the middle is the contact area of ​​the first touch area and the second touch area. When the finger touches from left to right, the first touch area is touched first, then the first touch area and the second touch area are touched at the same time, and finally the second touch area is touched. This is consistent with the process that the first valid signal is generated first, then the second valid signal is generated, and finally the third valid signal is generated. The overall process is to generate a signal on the left, then a signal in the middle, and finally a signal on the right. Then if the reverse is also true, if the finger touches from right to left, then the second touch area is touched first, then the first touch area and the second touch area are touched at the same time, and finally the first touch area is touched, at this time, the third valid signal is generated first, then the second valid signal is generated, and finally the first valid signal is generated. This order is also recognized. Therefore, there are two triggering sequences, corresponding to different instructions.

[0042] In this embodiment, if the first sequence and the second sequence are the same, it proves that the current operation is the same as the previous operation. If they are different, it proves that the current operation is different from the previous operation. Therefore, the first corresponding instruction can be an instruction to repeat the previous operation, and the second corresponding instruction is an instruction opposite to the previous operation. For example, the action of the previous operation is from left to right, the first valid signal is generated first, then the second valid signal is generated, and finally the third valid signal is generated, and the execution is to increase by 1 gear, from 0 gear to 1 gear. If the current operation is also from left to right, the execution repeats the previous operation or increases by 1 gear, from 1 gear to 2 gear. If it is from right to left, the opposite operation of the previous operation is performed, which is to decrease by 1 gear, from 2 gear to 1 gear.

[0043] In this embodiment, the first operation after receiving the wake-up signal is recorded as the first operation. At this time, there is no order in which the touch positions corresponding to the first valid signal, the second valid signal, and the third valid signal are triggered, so there is no second order. Therefore, there is no need to determine whether the first order and the second order are the same. At this time, the order in which the touch positions corresponding to the current first valid signal, the second valid signal, and the third valid signal are triggered corresponds to different instructions, such as the third corresponding instruction and the fourth corresponding instruction. The third corresponding instruction can be an upshift instruction, and the fourth corresponding instruction can be a downshift instruction.

[0044] like Figure 3 As shown, in one embodiment, a touch control device is provided, which may specifically include: a wake-up monitoring module, a touch monitoring module and a processing module; The touch control device includes a wake-up monitoring module, a touch monitoring module and a processing module; The wake-up monitoring module is connected to the processing module and is used to monitor the user's wake-up operation; The touch monitoring module is connected to the processing module and is used to monitor the user's touch operation. The touch monitoring module includes a first touch area and a second touch area. The first touch area and the second touch area are arranged side by side or nested to form a whole. The processing module is used to execute the above touch control method according to the inputs of the wake-up monitoring module and the touch monitoring module.

[0045] In this embodiment, the touch module includes a first touch area and a second touch area, and the two touch areas are arranged side by side or nested to form a whole. Figure 5 As shown, the nesting method is as follows Figure 4 As shown. The user can trigger the processing module to execute the instruction function corresponding to the operation by performing a touch operation on the touch module, and obtain a richer correspondence between the operation instructions through different combinations of the detection signals of the two touch areas. It can be understood that the touch module can also include more touch areas such as a third touch area and a fourth touch area, wherein two adjacent touch areas are arranged side by side or nested. Forming a whole here means that the touch area forms a whole in the presented visual effect, which does not mean that the entire touch area as a whole detects the user's touch operation and outputs two detection results of 0 and 1. It can be understood that the detection results output by the first touch area and the second touch area do not interfere with each other. The 0 and 1 here are just an example, which does not mean that the output is 0 and 1. It can be a detection result with no output and with output, or other situations.

[0046] In this embodiment, the processing module is the center of execution control, including power supply control, command control, display control, etc., and may also include gear control. The processing module mainly includes a control chip and related peripheral circuits, and the related peripheral circuits may be clock circuits, voltage stabilization circuits, filter circuits, etc.

[0047] In this embodiment, the first touch area forms a protrusion, and the second touch area forms a concave part that cooperates with the protrusion. The protrusion and the concave part are nested and connected to form the touch area of ​​the touch monitoring module. The protrusion of the first touch area and the concave part of the second touch area cooperate with each other to form an integral area (it should be noted that after the integral area is formed, the two touch points are still detected by partitions, and each partition or the overall area is not necessarily visible on the product appearance. The partition or overall area here only refers to the area where the detection is effective), so that the user can divide the overall area into three areas, an area with only the first touch area, an area with the first touch area and the second touch area, and an area with only the second touch area. Different corresponding instructions are determined according to the order of the effective signals generated according to the changes in the three areas.

[0048] In this embodiment, the protruding portion of the first touch area and the concave portion of the second touch area are both triangular, and the junction of the two touch areas is a < shape or a > shape (taking left and right sliding touch as an example). In this way, even if the sliding direction is tilted during the user's operation, the junction can still be detected. Figure 4 Compared with the method of setting the two touch areas to be of the same size and shape and having a vertical line as the boundary, that is, the two extending the process of generating the second effective signal, the second effective signal can be detected more effectively, such as Figure 5 shown.

[0049] In this embodiment, the touch control device further includes modules such as a power module, a communication module, and an indicator light module.

[0050] A touch control device provided by an embodiment of the present invention enables touch monitoring after receiving a wake-up signal; monitors the first touch area to determine whether the first touch area generates a first valid signal; if the first touch area generates a first valid signal, simultaneously monitors the first touch area and the second touch area, and determines whether a second valid signal is generated according to the states of the first touch area and the second touch area; if a second valid signal is generated, monitors the second touch area to determine whether the second touch area generates a third valid signal; if a third valid signal is generated, determines and executes the corresponding instruction according to the first valid signal, the second valid signal, and the third valid signal. In this way, by monitoring the touch states of the first touch area and the second touch area to determine whether the first valid signal, the second valid signal, and the third valid signal are generated in sequence, and then the corresponding instruction is determined according to the first valid signal, the second valid signal, and the third valid signal, the accurate correspondence between the operation and the instruction is achieved, and the generation order of the first valid signal, the second valid signal, and the third valid signal corresponds to different instructions, which increases the richness of the instructions.
