Description

Technical Field

[0001] The present invention relates to the field of human-computer interaction, and in particular to a full-area touch structure and an implementation method thereof. Background Art

[0002] At present, the development of the home furnishing industry has become more active with the development of intelligent technology. Based on the continuous progress of artificial intelligence, Internet of Things, cloud computing and other technologies, the functions and performance of smart home systems are constantly improving. However, due to the uncertainty of the home use environment, the operating performance is reduced. For example, the existing touch screens and touch pads, due to the uncertainty of the current environment, usually referring to the climate, temperature, humidity and storage time, will cause the internal structure to become unstable, and the threshold of the screen and touch pad will change, resulting in low sensitivity, slow response or unresponsiveness. This is especially common for large-area touch pads.

[0003] Secondly, the traditional touch technology mainly relies on the local touch area to realize functional operation. This method has certain limitations. For example, the existing full-area touch structure is generally integrated on the upper part of the controller, which causes the controller to emit heat. The temperature change will affect the thresholds on each pad on the touch panel. In addition, the signal detection point area that can be set on the touch panel is limited, resulting in insensitive touch. Especially when different touch modes appear, the system will crash due to detection problems, which limits the freedom and efficiency of user interaction to a certain extent, especially in scenarios that require large-area, high-precision touch operations. Therefore, the development of a full-area touch structure and implementation method to achieve full coverage and precise control of the device surface has become an urgent need for current technological development. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art. In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A full-area touch structure comprises a bottom shell, a full-area touchpad, a face cover and a touch panel, wherein a support plate is arranged at the inner edge of the bottom shell, the full-area touchpad is arranged on the support plate, the touch panel is arranged in the middle of the face cover, and a card slot is also provided at the upper edge of the bottom shell, a buckle is arranged at the bottom edge of the face cover, and the buckle corresponds to the card slot one by one; a pressing block is also arranged on the bottom shell, one end of the pressing block is exposed to the outside, and the other end extends into the card slot, a plurality of pads are distributed in an array on the upper part of the full-area touchpad, and the pads are vertically divided into three areas a, b and c, and a detection point is arranged in each area; the bottom of the full-area touchpad is also electrically connected to a processing module, a transmission module and a touch feedback module.

[0006] Preferably, a vibration motor is further disposed inside the bottom shell, and the vibration motor is electrically connected to the touch feedback module.

[0007] Preferably, the touch panel has RGB lamp beads, and the RGB lamp beads are also electrically connected to the touch feedback module.

[0008] Preferably, a method for implementing a full-area touch structure comprises the following steps:

[0009] S1: Divide the global touch panel into regions, and then set detection points in different regions;

[0010] S2: Obtain the signal values ​​actually detected in different areas of the global touch panel in the current environment, record the corresponding value flags, and then reset the values ​​to zero;

[0011] S3: Detecting the actual touch signal values ​​of the detection points in each divided area of ​​the global touch panel, and setting a suitable trigger threshold value according to the actual touch signal values ​​obtained by the acquisition;

[0012] S4: The processing module determines the trigger state through the touch feedback module, and then determines whether the touch response is successful according to whether the different trigger states meet the trigger conditions, and transmits the successful response signal to the device through the transmission module (11) to execute relevant instructions.

[0013] Preferably, the trigger state mainly includes a single-click state, a sliding state and a multi-finger trigger state.

[0014] Preferably, the specific steps for determining whether a response is successful are as follows:

[0015] If it is a trigger single-click state, if the signal value in the trigger area exceeds the set trigger threshold, the touch response is considered successful;

[0016] If the sliding state is triggered, after the current area is triggered, it is detected that more than three adjacent areas are also triggered within a specified time, and the sliding touch response is determined to be successful;

[0017] If the multi-finger touch state is triggered, after detecting that the current area is triggered and then the area separated by a specified time is triggered, it is determined that the multi-finger trigger response is successful.

[0018] Preferably, the trigger threshold is dynamically adjusted according to the force of the single click and the current environment. The force of the single click is determined by the difference in the number of times the capacitance of the touch area is charged and discharged per unit time when the touch occurs, that is, the larger the difference, the larger the capacitance and the greater the force of the single click.

[0019] Preferably, the calculation formula of the threshold value of the subsequent touch area when the touch occurs is:

[0020] C Y =100-(C1 / C0×100 / 2)

[0021] in:

[0022] C0 is the number of charge and discharge times before touching;

[0023] C1 is the number of charge and discharge times when touching;

[0024] C y This is the threshold of the subsequent touch area when this touch occurs.

[0025] Preferably, the calculation formula for dynamically adjusting the trigger threshold is:

[0026] X Y =X0+X n +(20×X1 / X0)

[0027] in:

[0028] X0 is the initial value of the touch threshold;

[0029] X n is the difference between environment and laboratory, usually 10;

[0030] X1 is the post-touch threshold;

[0031] X y The trigger threshold for all subsequent areas when this touch ends.

[0032] The beneficial effects of the present invention are:

[0033] The global touch panel structure has several pads distributed in an array, each of which is divided into three areas, a, b, and c. Each area is used as a signal detection point for signal detection. For example, if 10 pads are designed on the entire surface, each pad is divided into three equal areas, and the final signal detection points are 30. In this way, the signal detection points are increased, and the pads of the array form a coverage area, which can better realize the accurate capture of touch signals, while improving the response time and sensitivity. The touch feedback template provides real-time tactile, visual and other forms of feedback based on the user's touch operation, enhancing the user's perceptual experience. Secondly, according to the diversity of implementation methods and touch methods, it is no longer limited to single-click or long-press methods, and two methods of multi-touch and sliding touch are added to enrich the application scenarios.

[0043] Embodiment 1

[0044] See also Figure 2-6The present invention provides a full-area touch structure, comprising a bottom shell 1, a full-area touch pad 2, a cover 3 and a touch panel 4, wherein a support plate 5 is arranged at the inner edge of the bottom shell 1, the full-area touch pad 2 is arranged on the support plate 5, the touch panel 4 is arranged in the middle of the cover 3, and a card slot 6 is also provided at the upper edge of the bottom shell 1, a buckle 7 is arranged at the bottom edge of the cover 3, and the buckle 7 corresponds to the card slot 6 one by one; a pressing block 8 is also arranged on the bottom shell 1, one end of the pressing block 8 is exposed to the outside, and the other end extends into the card slot 6, through The buckle 7, the slot 6 and the pressing block 8 are mainly used to facilitate disassembly. A plurality of pads 9 are distributed in an array on the upper part of the full-area touch panel 2. The surface of each pad 9 is divided into three areas a, b and c. A detection point is set in each area. The bottom of the full-area touch panel 2 is also electrically connected to a processing module 10, a transmission module 11 and a touch feedback module 12. The processing module 10 receives the detection signal, identifies and processes it, and the feedback module 12 feeds back the touch operation of the device to the user in real time.

[0045] A vibration motor 13 is further disposed inside the bottom housing 1 , and the vibration motor 13 is electrically connected to the touch feedback module 12 .

[0046] The touch panel 4 has RGB lamp beads, which are also electrically connected to the touch feedback module 13 .

[0047] Touch and visual feedback flow:

[0048] The tactile feedback is mainly achieved through the vibration motor 13. A vibration motor 13 is built into the device. Whenever a touch is performed, the vibration motor 13 will synchronously generate vibrations and feedback to the human body through the cover 3 to form feedback. The visual feedback part is mainly provided by combining RGB lamp beads into different lighting effects. Whenever a touch is performed, the corresponding lighting effect will be triggered to achieve the feedback effect.

[0049] Reference Figure 1 , a method for realizing a full-area touch structure, comprising the following steps:

[0050] S1: Divide the global touch panel 2 into regions, and then set detection points in different regions;

[0051] S2: Obtain the signal values ​​actually detected in different areas of the global touch panel 2 in the current environment, record the corresponding value marks, and then reset and zero the values;

[0052] S3: Detecting the actual touch signal values ​​of the detection points in each divided area of ​​the global touch panel 2, and setting a suitable trigger threshold value according to the actual touch signal values ​​obtained through the acquisition;

[0053] S4: The processing module 10 determines the trigger state through the touch feedback module 12, and then determines whether the touch response is successful based on whether the different trigger states meet the trigger conditions, and transmits the successful response signal to the device through the transmission module (11) to execute related instructions.

[0054] The triggering states mainly include a single-click state, a sliding state and a multi-finger triggering state.

[0055] The specific steps to determine whether a response is successful are as follows:

[0056] If it is a state of triggering a single click, if the signal value in the trigger area exceeds the set trigger threshold, the touch response is considered successful;

[0057] If the sliding state is triggered, after the current area is triggered, it is detected that more than three adjacent areas are also triggered within a specified time, and the sliding touch response is determined to be successful;

[0058] If the multi-finger touch state is triggered, after detecting that the current area is triggered and then the area separated by a specified time is triggered, it is determined that the multi-finger trigger response is successful.

[0059] From step S3, we know that each area has a trigger threshold, which is the trigger threshold of a single click. In terms of action distinction, sliding triggers multiple touch pads in a short time, so the time and force of staying on each touch area will be less than that of a single click. Therefore, the trigger threshold of each subsequent touch area is dynamically adjusted according to the force of the single click and the current environment. The smaller the touch force, the easier it is to trigger the threshold when it is dynamically adjusted.

[0060] The single-click force is determined by the physical characteristics of the capacitor corresponding to the detection point on each pad. The difference in the number of times the capacitor is charged and discharged per unit time represents the single-click force; the larger the difference, the larger the capacitance and the greater the single-click force.

[0061] The calculation formula of the threshold value of the subsequent touch area when the touch occurs is:

[0062] C Y =100-(C1 / C0×100 / 2)

[0063] in:

[0064] c0 is the number of charge and discharge times before touching;

[0065] c1 is the number of charge and discharge times when touching;

[0066] C y This is the threshold of the subsequent touch area when this touch occurs.

[0067] For example:

[0068] In the current environment variable, the signal value before touching is 100. In actual testing, when the difference between the number of charge and discharge times before touching and when touching reaches 100, it means that touching occurs. When sliding occurs, due to the short time and light force, if the default value is still used for the algorithm, it will be difficult for sliding to take effect. After touching, the difference of subsequent touch areas is dynamically reduced, such as: the number of charge and discharge times before touching C0 = 1000, when touching C1 = 850, C0-C1 = 150 is greater than the touch threshold of 100, indicating that touching occurs, and the threshold of subsequent touch areas becomes 100-(C1 / C0×100 / 2) = 55. As long as the subsequent touch threshold is greater than 55, it is considered triggered. When the touch ends, it is determined whether the area meets the triggering conditions for sliding. The difference between multi-finger touch and sliding is that sliding is triggered by continuous multi-touch areas, while multi-finger touch is triggered by discontinuous multi-touch areas.

[0069] The calculation formula for the dynamic adjustment of the trigger threshold is:

[0070] X Y =X0+X n +(20×X1 / X0)

[0071] in:

[0072] X0 is the initial value of the touch threshold;

[0073] X n is the difference between environment and laboratory, usually 10;

[0074] X1 is the post-touch threshold;

[0075] X y The trigger threshold for all subsequent areas when this touch ends.

[0076] Dynamic update of trigger thresholds:

[0077] Since full-area touch inevitably has a problem, the signal accuracy collected between different areas is bound to be different due to the large area. To address this technical problem, the signal accuracy threshold adjustment optimization of different areas is achieved through dynamic adjustment, so that the collected touch signals can be quickly and accurately identified and processed. At the same time, multi-touch and sliding touch are also added through algorithms.

[0078] Specifically, if the touch threshold is originally 70, and after the touch, the value becomes 40. According to the calculation formula for dynamic adjustment, the touch thresholds of all subsequent touch areas before the current touch ends become: 70+10+(20×40 / 70)=91.

[0079] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
