Referring to fig. 1, fig. 1 is an architecture diagram of a processing system 100 for a tactile signal according to an exemplary embodiment of the invention, where the processing system 100 may include a touch device 120 and a host device 140, the touch device 120 may include a touch sensor 121, the host device 140 is loaded with an operating system (not shown in fig. 1), and the operating system may include a signal processing code 141, a virtual touch device 142, and an input subsystem 143.
The host device 140 may refer to a host of an electronic device or a part of the host for implementing a touch response, the touch device 120 may refer to a touch input device independent of the electronic device, or may refer to a touch input device installed on various electronic devices, where the electronic device may be a laptop computer, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an intelligent writing device, an email transceiver, a game console, a tablet computer, a wearable device, a smart car, an unmanned vehicle, a smart refrigerator, other smart home devices, or a combination of any of these devices. The intelligent writing device may be an electronic whiteboard, an electronic blackboard, or the like.
The corresponding touch screen type of the touch device 120 may be various types such as electromagnetic type, infrared type, capacitance type, resistance type, pressure type, etc., for example: the touch screen type of the smart phone is a capacitive type or a resistive type, the touch screen type of the smart writing board is an electromagnetic type, and the touch screen type of the infrared display is an infrared type.
When the types of the touch screens corresponding to the touch device 120 are different, the types of the touch sensors 121 are different, the touch signals acquired by the touch sensors are different, the converted touch signals are also not completely different, and several touch sensors 121 are listed for different types of touch screens as follows:
the type one is as follows: the touch screen is an infrared touch screen, the touch sensor 121 is an infrared touch frame, the touch signal collected by the infrared touch frame may include a signal indicating that infrared rays are blocked, and the converted touch signal may include a position touch signal, which may include an X coordinate and a Y coordinate of a touch position.
Type two: the touch screen is an electromagnetic touch screen, the touch sensor 121 is an electromagnetic plate, the touch sensing signal collected by the electromagnetic touch screen may include a variation of magnetic flux and a frequency of the received electromagnetic signal, the touch signal obtained by conversion may include a touch position signal corresponding to the variation of magnetic flux and a pressure sensing signal corresponding to the frequency, and the touch position signal may include an X coordinate and a Y coordinate of the touch position. The pressure-sensitive signal may include a pressure value.
Type three: the touch screen is a capacitive touch screen, the touch sensor 121 is a capacitive touchpad, the touch sensing signals collected by the capacitive touchpad may include currents flowing through electrodes of the touch screen, and the converted touch signals may include position touch signals, which may include X coordinates and Y coordinates of a touch position.
Type four: the touch screen is a resistive touch screen, the touch sensor 121 is a resistive touch pad, the collected touch signal may include a voltage of a touch position, and the converted touch signal may include a position touch signal, which may include an X coordinate and a Y coordinate of the touch position.
Type five: the touch screen is a pressure sensitive touch screen, the touch sensor 121 is a pressure sensor, the tactile signal collected by the pressure sensor may include a pressure signal, and the converted touch signal may include a position touch signal, which may include an X coordinate and a Y coordinate of a touch position.
In other examples, the touch screen of the touch device 120 may include at least two of an electromagnetic touch screen, an infrared touch screen, a capacitive touch screen, a resistive touch screen, and a pressure sensitive touch screen, and accordingly, the touch sensor 121 may include at least two of an infrared touch frame, an electromagnetic plate, a capacitive touch panel, a resistive touch panel, and a pressure sensor. Alternatively, the touch device 120 may also be another type of touch screen, and this is not limited in this embodiment.
After the touch sensor 121 collects the touch sensing signal, when the touch device 120 transmits the touch sensing signal to the operating system, if the touch sensor 121 is a device having both a control function and a collection function, such as a touch sensing chip, the touch sensor 121 may directly transmit the touch sensing signal to the operating system through a predetermined interface. The predetermined Interface mentioned here may be a USB-bulk Interface, an RS232 Interface, or a USB-hid Interface (hid is an abbreviation of Human Interface Devices, i.e., man-machine Interface device), and the USB-hid Interface may be a universal USB-hid Interface, and furthermore, the predetermined Interface may also be a signal transmission Interface customized by a designer or other device manufacturer of the solution of the present invention.
In another example, the touch device 120 may further include a touch processing device (not shown in fig. 1), and when the touch device 120 transmits a touch signal to the operating system, if the touch sensor 121 does not have a control function, the touch processing device may read the touch signal from the touch sensor 121 and transmit the touch signal to the operating system through the predetermined interface. The touch processing device mentioned herein may be a main control chip (also referred to as a main processing chip or a central processing unit) of the touch device 120, or may be other processing chips, and the processing chip may be installed in the touch device 120 or disposed outside the touch device 120.
For the signal processing code 141, when converting the touch signal into the touch signal, corresponding to different types of touch screens, the conversion may be performed by adopting a corresponding conversion method based on the operating principle of each type of touch screen. For example: the touch signal is a current generated by the capacitive touch screen and flowing through each electrode of the touch screen, and an X coordinate and a Y coordinate of the position of the touch point can be determined according to the proportion of currents at all levels.
The signal processing code 141, as a logical module, can be formed by reading corresponding computer program instructions in a readable medium such as a non-volatile memory into a memory for operation through a central processing unit (also referred to as a main control chip or a main processing chip) of the host device 140 or another processing chip other than the central processing unit. The central processor of host device 140 or another processing chip other than the central processor may read program instructions stored in its memory and, in response, convert the tactile signal to a touch signal.
The virtual touch device 142 is a virtual device that has functions of the touch device 120 and is run in an operating system, and after the virtual touch device is started to run, a data encoding specification of a signal that is transmitted to the input subsystem 143 after the virtual touch device is started to run may be predetermined to the input subsystem 143, that is, a data encoding specification supported by the input subsystem 143. In practical applications, when the types of the touch devices 120 are different, the virtual touch device 140 is also different, for example: the touch device 120 is an infrared touch frame device and the virtual touch device 140 is a virtual touch frame device.
In some examples, the data encoding specification supported by the input subsystem 143 may be a valid touch data protocol extracted from a USB multi-touch hid protocol corresponding to the USB-hid interface. It is emphasized that "abstraction" means that the standard USB multi-touch hid protocol adds some headers, messages, etc. required by the USB transport protocol to the active touch data protocol for USB protocol transport, which is not required in the added data input subsystem. In addition, the data encoding specification supported by the input subsystem 143 may also be a data encoding specification predetermined by a designer according to an application requirement of the touch device 120, and the embodiment of the present specification is not limited herein.
The input subsystem (input _ device)143 may be composed of a device driver layer, an input core layer, and an event processing layer, where the device driver layer may convert hardware input at the bottom layer into a uniform event form, report the uniform event form to the input core layer, and the input core layer may be started and stopped to register and operate an interface for the device input by the hardware driver layer, and notify the event processing layer to process the event.
In some scenarios, the processing system 100 may be applied to an electronic device, the touch device 120 may further include a touch screen, and the touch sensor 121 may be disposed on the touch screen or may be independent of the touch screen. The processing system 100 may also include an interface (the predetermined interface described above) provided between the touch device 120 and the operating system. When a user contacts the touch screen through a finger or a writing pen, the touch sensor 121 may generate a touch sensing signal, the touch device 120 sends the touch sensing signal to the operating system, the signal processing code 141 in the operating system may convert the received touch sensing signal into a touch signal and send the touch signal to the virtual touch device 142, then the virtual touch device 142 encodes the touch signal according to a data encoding specification supported by the input subsystem 143 and sends the encoded touch signal to the input subsystem 143, and the input subsystem 143 responds to the encoded touch signal to generate a corresponding touch event.
When the touch device 120 sends the tactile signal to the operating system, the tactile signal may be transmitted through the predetermined interface according to different requirements, for example: when the communication speed is higher, the touch signal can be transmitted through the USB-bulk interface; if the communication speed is required and the communication stability is required to be high, the touch signal can be transmitted through the USB-hid interface; if the communication process is required to be simplified, the touch signals can be transmitted through the RS232 interface, and before the touch signals are transmitted through the corresponding interface, the touch signals are converted into the protocol supported by the corresponding interface and then transmitted through the corresponding interface. In other examples, when there are other needs, other types of interfaces may be adopted to transmit the tactile signal, and this is not limited by the embodiments of the present disclosure.
After the signal processing code 141 converts the tactile signal into the touch signal and transmits the touch signal to the virtual touch device 142, a data encoding specification adopted when the virtual touch device 142 encodes the touch signal may be related to the type of the touch screen of the touch device 120.
For example, when the touch device 120 is an electromagnetic touch device, the adopted data encoding specification may be a USB protocol supporting single electromagnetic pen input, the touch signal is encoded as a touch signal triggered by a single electromagnetic pen, and then the encoded touch signal is mapped into a packet of the USB protocol.
In practice, the touch signal may be mapped into the body of the USB protocol in the format (corresponding to the descriptor of the hid pen) in table 1 below:
table 1:
for another example, when the touch device 120 is a capacitive touch device, the adopted data coding specification may be a multi-touch protocol, and during coding, the touch signal is coded into data meeting a format specified by the multi-touch protocol, and then the coded touch signal is packaged into a packet of the same data packet.
In practice, the touch signals may be mapped into the inclusion of the multi-touch protocol in the format (descriptor corresponding to hid multi-touch) in table 2 below:
table 2:
as shown in table 2, the data of the 1 st touch point, including status, ID, X, Y, Pressure information, correspond to byte numbers 1 to 8; data of the 2 nd point touch point, including state, I D, X, Y, Pressure information, corresponding to byte numbers 9 to 16; the byte number 17 indicates that there are several touch points (several pens) in the current packet.
In some examples, the resolution of the touch screen corresponding to the touch device 120 is 32767 × 32767, the origin of the coordinates is the upper left corner of the touch screen, and the touch signal may include data of a relatively large number of touch points, for example, position coordinates including more than six pixel points.
In practical application, block coding is performed, and when each block is coded, the touch signal can be mapped into the packet body of one data packet according to the format in the following table 3:
table 3:
each data packet contains data of 6 touch points at most, each data packet is sent respectively, the first data packet sent may include the number of valid touch points triggered this time, other data packets send 0x00 at corresponding positions, and the input subsystem 143 may distinguish different touch points by the ID of the touch point.
After the encoded touch signal is received by the input subsystem 143, the touch signal may be analyzed by using a corresponding protocol, and then the touch signal is converted into a corresponding touch event.
The following describes a tactile signal processing procedure applied to an operating system, with reference to the accompanying drawings:
referring to fig. 2, fig. 2 is a flowchart illustrating a method for processing a touch sensing signal according to an exemplary embodiment of the invention, where the embodiment is applied to an operating system, and may include the following steps S201 to S203:
