[0009] In one embodiment of this application, the event detection method further includes: after power-on startup, obtaining the first pressure value and the second pressure value from a configuration file in a preset storage space.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone, where A and B can be singular or plural. The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and drawings of this application are used to distinguish similar objects, not to describe a specific order or sequence.
[0026] It should also be noted that the methods disclosed in the embodiments of this application or the methods shown in the flowcharts include one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged, and some steps can also be deleted.
[0027] Currently, most existing full-area pressure-sensitive touch input devices use a single pressure threshold, which can only output a single button-triggered event, making it difficult to recognize and output multiple events. For example, when using a touch input device to replace a mouse, it is difficult to distinguish between the left and right mouse button events.
[0028] In existing technologies, a single touch is generally used to implement the left mouse button event, while a two-finger gesture or area logic is used to implement the right mouse button event. This results in complex operation of touch input devices and a relatively high rate of accidental touches.
[0029] This application provides an event detection method, touchpad, and touch input device for a touch input device, which reduces the operational complexity of the touch input device and lowers the false touch rate of multi-event recognition in the touch input device.
[0030] Please refer to Figure 1 , Figure 1 This is a schematic block diagram of a touch input device provided in an embodiment of this application. The touch input device 100 includes a touch panel 110 and a controller 120, with the controller 120 connected to the touch panel 110.
[0031] In this embodiment, the touch input device 100 includes a standalone touchpad 110, a keyboard with a touchpad 110, an embedded touchpad 110, and industrial touch devices, etc. The standalone touchpad 110 includes products such as Apple's Magic Trackpad that communicate and interact with computer devices via wireless communication, while the embedded touchpad 110 includes touch devices found on various brands of laptops.
[0032] The touchpad 110 is used to detect touch pressure and transmit it to the controller 120. For example, the touchpad 110 of the touch input device 100 may include a pressure sensor to detect the user's touch pressure. Upon detecting a target touch pressure, the pressure sensor triggers an event output, enabling the computer device to receive the event and execute related control logic. For example, the touchpad 110 may include a piezoresistive pressure sensor, a piezoelectric pressure sensor, or a capacitive pressure sensor to detect touch pressure. The controller 120 is connected to the pressure sensor to acquire the touch pressure detected by the pressure sensor.
[0033] Next, combined Figure 1 This application provides an embodiment of an event detection method for a touch input device. Please refer to [link / reference]. Figure 2 Specifically, it includes the following steps: Step S21: In response to any area of the touchpad being touched, control the touchpad's sampling rate to increase to the target sampling rate.
[0034] Specifically, when the touchpad has not detected any touch operation for an extended period, the controller can put the touchpad into a sleep state. In sleep mode, the touchpad maintains a lower sleep sampling rate to conserve power, thereby reducing the power consumption of electronic devices equipped with touch input devices. The sleep sampling rate is lower than the aforementioned target sampling rate.
[0035] When the touchpad detects a touch operation, the controller can instruct the touchpad to increase its current sampling rate to a target sampling rate, allowing the touchpad to more accurately detect the magnitude of the touch pressure. For example, the aforementioned sleep sampling rate can be less than or equal to 60Hz, while the target sampling rate can be greater than or equal to 130Hz.
[0036] Step S22: When the touch pressure of any area of the touchpad being touched is greater than or equal to the first pressure value and less than the second pressure value, output the first event.
[0037] In this embodiment, after detecting touch pressure, the touchpad can convert the touch pressure into a digital signal and transmit it to the controller. Simultaneously, the touchpad can also transmit information about the area where the touch pressure occurred to the controller. Upon receiving the digital signal of the touch pressure and the area information, the controller first identifies the magnitude of the pressure value based on the digital signal. When the controller determines that the touch pressure is greater than or equal to a first pressure value and less than a second pressure value, it outputs a first event.
[0038] Step S23: When the touch pressure of any area of the touchpad is greater than or equal to the second pressure value, output the second event.
[0039] In this embodiment of the application, after receiving the digital signal of the touch pressure and the area information, the controller determines that the second touch pressure is greater than the second pressure value, and outputs the second event. That is, when the touch pressure in any area of the touchpad is greater than the second pressure value, the controller directly outputs the second event.
[0040] The first event includes a left-click event, and the second event includes a right-click event. Alternatively, the first event includes a right-click event, and the second event includes a left-click event, thus enabling the touch input device to output mouse left-click events while also outputting mouse right-click events across the entire area.
[0041] Step S24: The touchpad converts the second event into a specific event code, which is used to trigger system-level functions.
[0042] In this embodiment of the application, for example, when the touch input device is applied to a Windows system computer, the firmware in the touchpad can convert the second event into a specific event code including HID Usage 0x9002 in the Windows Precision TouchPad protocol. HID Usage 0x9002 is used to trigger the right-click function of the Windows system, so that the touch input device does not need additional drivers or upper-level gesture recognition to output the specific event code of the right click, thereby reducing latency and improving compatibility.
[0043] It is understood that this application configures a first pressure value and a second pressure value for the touch input device. When the touch pressure in any area of the touchpad is greater than or equal to the first pressure value and less than the second pressure value, the controller outputs a first event, including a left-click event. When the touch pressure in the entire area of the touchpad is greater than or equal to the second pressure value, the controller outputs a second event, including a right-click event. This enables the recognition and output of both left-click and right-click events on the touch input device, better distinguishes between the two types of events, reduces the false touch rate of multi-event recognition on the touch input device, and reduces the operational complexity of the touch input device.
[0044] Please refer to Figure 3 , Figure 3 This is a schematic block diagram of another touch input device provided in an embodiment of this application, wherein the touch input device 100 further includes a vibration motor 130, and the vibration motor is connected to a controller 120.
[0045] The vibration motor 130 is used to output a vibration feedback signal. For example, after the controller 120 outputs a first event or a second event, it can control the vibration motor 130 to output a vibration feedback signal and maintain the response time to remind the user of the touch input device 100 that the operation was successful.
[0046] Next, combined Figure 3This application introduces a second event detection method for a touch input device, as described in its embodiments. Please refer to [link / reference needed]. Figure 4 Specifically, it includes the following steps: Step S41: After power-on startup, obtain the first pressure value and the second pressure value from the configuration file in the preset storage space.
[0047] In this embodiment, a configuration file for the touch input device can be stored in a preset storage space within the computer device. This configuration file stores the aforementioned first pressure value and second pressure value. After power-on, the touch input device establishes a communication connection with the computer device. The controller 120 of the touch input device can access the configuration file in the computer device to obtain the first pressure value and the second pressure value.
[0048] In some embodiments, a user can adjust a first pressure value and a second pressure value in a configuration file by operating a computer device. Furthermore, different users can have different configuration files. For example, when user A logs into the computer device, the controller 120 of the touch input device can access configuration file A in the computer device, while when user B logs into the computer device, the controller 120 of the touch input device can access configuration file B in the computer device, thereby enabling personalized pressure value settings for the touch input device.
[0049] Step S42: In response to any area of the touchpad being touched, control the touchpad's sampling rate to be increased to the target sampling rate.
[0050] Step S43: When the touch pressure of any area of the touchpad being touched is greater than or equal to the first pressure value and less than the second pressure value, output the first event.
[0051] Step S44: When the touch pressure of any area of the touchpad being touched is greater than or equal to the second pressure value, output the second event.
[0052] Step S45: The touchpad converts the second event into a specific event code, which is used to trigger system-level functions.
[0053] Step S46: In response to the output of the second event, control the vibration motor to vibrate for a first preset duration.
[0054] In this embodiment, when the controller outputs the second event, it controls the vibration motor to vibrate for a first preset duration to output a vibration feedback signal for the first preset duration. For example, when the second event is a right-click event, the controller controls the vibration motor to vibrate for the first preset duration to inform the user that the right-click function has been successfully triggered.
[0055] Please refer to Figure 5 , Figure 5A flowchart illustrating the third event detection method for a touch input device provided in this application embodiment, specifically including the following steps: Step S51: In response to any area of the touchpad being touched, control the touchpad's sampling rate to be increased to the target sampling rate.
[0056] Step S52: When the touch pressure of any area of the touchpad being touched is greater than or equal to the first pressure value and less than the second pressure value, output the first event.
[0057] Step S53: When the touch pressure of any area of the touchpad being touched is greater than or equal to the second pressure value and the duration is greater than the first time window, output the second event.
[0058] Step S54: The touchpad converts the second event into a specific event code, which is used to trigger system-level functions.
[0059] It is understandable that the controller outputs the second event only when it determines that the touch pressure in any area of the touchpad is greater than the second pressure value and the duration is greater than the first time window, so as to reduce the false touch rate of the second event.
[0060] Please refer to Figure 6 , Figure 6 A flowchart illustrating the fourth event detection method for a touch input device provided in this application embodiment, specifically including the following steps: Step S61: In response to any area of the touchpad being touched, control the touchpad's sampling rate to increase to the target sampling rate.
[0061] Step S62: When the touch pressure of any area of the touchpad being touched is greater than or equal to the first pressure value and less than the second pressure value, output the first event.
[0062] Step S63: When the touch pressure of any area of the touchpad being touched is greater than or equal to the second pressure value, output the second event.
[0063] Step S64: The touchpad converts the second event into a specific event code, which is used to trigger system-level functions.
[0064] Step S65: In response to the output of the first event or the second event, record the ambient temperature and the pressure value of the touch pressure.
[0065] In this embodiment of the application, a temperature sensor may also be provided in the touch input device. When the controller outputs the first event or the second event, the controller may also obtain the ambient temperature through the temperature sensor and record and store the corresponding pressure value associated with the ambient temperature.
[0066] Step S66: After a preset time interval, correct the first pressure value and the second pressure value based on multiple ambient temperatures and corresponding multiple pressure values.
[0067] In this embodiment of the application, after a preset time interval, that is, after the touch input device has been used for a preset time interval, the controller corrects the first pressure value and the second pressure value based on the recorded multiple ambient temperatures and corresponding multiple pressure values. For example, it can correct the detection error of the pressure value caused by environmental factors by sliding average filtering and temperature baseline compensation.
[0068] Please refer to Figure 7 , Figure 7 A flowchart illustrating the fifth event detection method for a touch input device provided in this application embodiment, specifically including the following steps: Step S71: In response to any area of the touchpad being touched, control the touchpad's sampling rate to be increased to the target sampling rate.
[0069] Step S72: When the touch pressure of any area of the touchpad being touched is greater than or equal to the first pressure value and less than the second pressure value, output the first event.
[0070] Step S73: When the touch pressure of any area of the touchpad being touched is greater than or equal to the second pressure value, output the second event.
[0071] Step S74: The touchpad converts the second event into a specific event code, which is used to trigger system-level functions.
[0072] Step S75: When the touch pressure of any area of the touchpad being touched is greater than or equal to the third pressure value, output the third event.
[0073] Step S76: In response to the output of the third event, control the vibration motor to vibrate for a second preset duration.
[0074] In this embodiment, the third pressure value is greater than the second pressure value, and the second pressure value is greater than the first pressure value. The first event can be a left mouse button event, the second event can be a right mouse button event, and the third event can be a user-defined event. For example, a user can configure the aforementioned custom event through the configuration program of the touch input device in a computer device. This custom event can be, for example, various shortcut commands, and the computer device executes the corresponding shortcut command in response to the third event.
[0075] Please refer to Figure 8 , Figure 8 A schematic block diagram of a touchpad provided in an embodiment of this application, wherein the touchpad 110 includes: The pressure detection module 111 is used to collect the touch pressure of any touch area on any touchpad.
[0076] The pressure judgment module 112 is used to determine whether the touch pressure meets the preset pressure value. When the touch pressure is greater than or equal to the first pressure value and less than the second pressure value, a first event is output. When the touch pressure is greater than or equal to the second pressure value, a second event is output.
[0077] Event conversion module 113 is used to convert the second event into a specific event code, which is used to trigger system-level functions.
[0078] Please refer to Figure 9 , Figure 9 A schematic block diagram of a third type of touch input device provided in the embodiments of this application, and...
