[0025] Figure 4 This is a flowchart of a touch mode switching method provided according to a third embodiment of the present invention. Detailed Implementation

[0026] The following are specific examples.

[0027] Figure 1 This is a functional block diagram of a touch mode switching system according to a first embodiment of the present invention. See also... Figure 1 The touch mode switching system 1 is applied to the touch input device 2 and the operating system 3, and the operating system 3 responds to operations on the touch input device 2 by default in the first touch mode, wherein the first touch mode is the finger touch mode. The touch input device 2 is, for example, the touch screen of a tablet computer or a mobile phone, but the present invention is not limited thereto.

[0028] Specifically, the touch mode switching system 1 includes a processing circuit 10 and a storage circuit 20. The processing circuit 10 is electrically connected to the touch input device 2, and the storage circuit 20 is electrically connected to the processing circuit 10.

[0029] The processing circuit 10 is, for example, one or any combination of a central processing unit (CPU), an embedded controller, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a microcontroller unit (MCU), and a system on a chip (SOC).

[0030] The storage circuit 20 is, for example, a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), or flash memory.

[0031] The storage circuit 20 stores the application program 30, which contains multiple instructions and data. The processing circuit 10 is configured to access the storage circuit 20 and execute the application program 30 to produce the following operations.

[0032] When the touch input device 2 receives multiple input data within a predetermined time, the application 30 determines the format of each input data.

[0033] The touch mode switching system 100 is equipped with an anti-mistouch mechanism. If the application 30 determines that the formats of multiple input data are not all consistent, it is considered an invalid input. Specifically, when the application 30 determines that the format of a portion of multiple input data conforms to a first format and the format of another portion of multiple input data conforms to a second format within a predetermined time, the application 30 maintains the operating system 3 in the first touch mode to respond to operations on the touch input device 2.

[0034] The first format is the data format for the stylus, and it defines the first object information, the first coordinate information, the stylus pressure information, and the stylus tilt angle information. For example, the first object information is 0x02.

[0035] The second format is the data format for the finger, and this second format defines second object information and second coordinate information. For example, the second object information is 0x03.

[0036] When application 30 determines that the format of each piece of input data conforms to the first format, it is considered a valid input. Application 30 switches operating system 3 from the first touch mode to the second touch mode in response to operations on touch input device 2, wherein the second touch mode is stylus mode.

[0037] For example, the touch input device receives 10 input data entries within 10 seconds. If all 10 entries conform to the stylus's data format, the application 30 will switch the operating system 3 from finger touch mode to stylus mode. If 9 out of the 10 entries conform to the finger data format, but only 1 conforms to the stylus's data format, it's possible the stylus accidentally touched the touch input device, so the application 30 will keep the operating system 3 in finger touch mode.

[0038] When the application 30 determines that the format of each input data within a predetermined time period conforms to the second format, it is considered a valid input. The processing circuit 10 further determines the touch sensing quantity corresponding to each input data, where the touch sensing quantity is, for example, capacitance.

[0039] Specifically, since the data format of a finger is the same as that of a glove, capacitance must be used to further distinguish the object touching the touch input device 2. Application 30 can only determine the data format and not the capacitance, so the capacitance determination is performed by processing circuit 10. Application 30 queries processing circuit 10 for the capacitance determination result at the touch location on touch input device 2. After receiving the capacitance determination result, application 30 determines whether the object touching touch input device 2 is a finger or a glove based on the capacitance. The capacitance generated by a glove touching touch input device 2 is greater than the capacitance generated by a finger touching touch input device 2.

[0040] When the processing circuit 10 determines that the touch sensing amount of each input data is equal to or greater than the sensing threshold, the application program 30 switches the operating system 3 from the first touch mode to the third touch mode to respond to the operation of the touch input device, wherein the third touch mode is the glove touch mode.

[0041] When the processing circuit 10 determines that each input data is less than the sensing threshold, the application program 30 maintains the operating system 3 in the first touch mode to respond to the operation of the touch input device 2.

[0042] When the processing circuit 10 determines that the touch sensing amount of a portion of the multiple input data is equal to or greater than the sensing threshold and the touch sensing amount of another portion of the multiple input data is less than the sensing threshold, the application program 30 maintains the operating system 3 in the first touch mode to respond to the operation of the touch input device 2.

[0043] Furthermore, if the application 30 is unable to determine the mode of the operating system 3 within a limited time, the application 30 will maintain the operating system 3 in the first touch mode.

[0049] When the format of each input data item conforms to the finger data format, proceed to step S205. The finger data format definition includes second object information and finger coordinate information.
