Detailed Description
Referring to fig. 1, the present invention is a system of impulse-like sensing keys, which includes: at least one key 10 and a processing unit 20.
The key 10 is a capacitive key, and when the key 10 is pressed, a key pressing signal corresponding to the pressing force intensity is output. As shown in fig. 2A, the key 10 has a key cap 11, a bridging mechanism 12, an elastic body 13, a conical elastic member 14 and a sensing circuit board 15; when the key cap 11 is not pressed, the elastic force of the elastic body 13 pushes the key cap 11 to a first position P1, and the conical elastic member 14 is not pressed or deformed by the pressing force, and at this time, the capacitance sensing area 151 of the sensing circuit board 15 does not generate capacitance sensing variation; then, as shown in fig. 2B, when the key cap 11 is pressed and moved from the first position P1 to a second position P2, the key cap 11 presses the top surface of the elastic body 13 downward, so that the elastic body 13 deforms downward and the tapered elastic element 14 also deforms downward in a compression manner, at this time, the tapered elastic element 14 and the capacitance sensing area 151 generate a change in compression distance, and the amount of change in the sensed capacitance (i.e., the sensed capacitance value) corresponds to the degree of pressing force, so as to output a key pressing signal corresponding to the strength of pressing force.
Of course, fig. 2A and 2B are only schematic diagrams illustrating the pressing operation of the present invention, and the position change of the key cap 11 is not limited to the first position P1 and the second position P2, but the tapered elastic member 40 can be compressed to different degrees according to the pressing force of the user pressing the key cap 11, so that the key cap 11 is located at different height positions. That is, when the user presses the keycap 11 with a larger intensity to generate a larger pressing stroke interval, the larger the pressing force generated by the conical elastic member 14 compressing the capacitance sensing area 151 of the sensing circuit board 15 is, the larger the value of the sensing capacitance sensed by the capacitance sensing area 151 is; that is, the value of the capacitance is proportional to the intensity of the pressing force. In application, the present invention measures IC output reference values, such as: 0-255, therefore, the reference value of the key pressing signal is inversely proportional to the pressing force (see fig. 3 and 4).
The processing unit 20 may be a general microprocessor, a combination of special purpose processors, or a related chipset for receiving and processing the key pressing signal; as shown in fig. 3, which is a graph of the relationship between the pressing of the key 10 and the time, when the key pressing signal is equal to a first reference CP1, a first time t1 is recorded, when the key pressing signal is equal to a second reference CP2, a second time t2 is recorded, and a first type impulse is calculated by the processing unit 20 and then output to an electronic device 30; wherein, the first impulse value is calculated by the following formula: l (CP2-CP1)/(t2-t 1).
More specifically, the electronic device may be a smart phone, a computer, a portable electronic device or a tablet computer, and performs corresponding processing according to the first class impulse value output by the processing unit 20; for example, the electronic device can process the game to different degrees according to the magnitude of the first impulse value, such as: the larger the first impulse type is, the larger the attack force of the game character is, and the smaller the first impulse type is, the smaller the attack force of the game character is.
As can be seen from fig. 3, the smaller the difference between the first time t1 and the second time t2, the larger the difference between the first time t1 and the second time t2, the smaller the difference between the first time t1 and the second time t2, and the smaller the difference between the first time t1 and the second time t2, and the larger the difference between the first time t 3526 and the second time t2.
Of course, the first class impulse calculated in the above description is a slope value of the pressing process of the key 10, and the processing unit 20 can calculate a slope value of the releasing process of the key 10 in addition to the slope value of the pressing process; please refer to fig. 4, which is a graph of the relationship between the pressing and releasing of the key 10 and time, according to the present invention, the setting of the second reference CP2 is greater than the maximum force point of the user, so that when the key pressing signal is equal to the second reference CP2, the key 10 is still pressed, the key pressing signal reaches a maximum force CP3, and the key 10 starts to be released; that is, after the processing unit 20 calculates the first type impulse value, the processing unit 20 can continuously receive the key pressing signal, when the key pressing signal is smaller than the second reference value CP2 and reaches a maximum force application value CP3, i.e. the releasing stroke of the key 10, the key pressing signal will be equal to the second reference value CP2 again, at this time, the processing unit 20 records a third time t3, when the key pressing signal is equal to the first reference value CP1 again, the processing unit 20 records a fourth time t4, and then the processing unit 20 calculates a second type impulse value and outputs the second type impulse value to the electronic device 30; wherein, the second impulse value is calculated by the following formula: l (CP1-CP2)/(t4-t 3).
Therefore, in the present invention, the first type of impulse value generated when the key 10 is pressed can be used for the electronic device 30 to perform corresponding processing, and the second type of impulse value generated when the key 10 is released can also be used as the basis for the electronic device 30 to perform processing, so that the electronic device 30 has more combination changes.
Please refer to fig. 5, which is a flowchart illustrating a method for sensing a button with similar impulse according to the present invention;
first, step S1: pressing a character key and continuously outputting a character key pressing signal; the key is a capacitive key, and when the key is pressed, a key pressing signal corresponding to the pressing force intensity is output.
Next, step S2: continuously receiving the key pressing signal by a processing unit 20; recording a first time t1 when the key pressing signal is equal to a first reference value CP1, recording a second time t2 when the key pressing signal is equal to a second reference value CP2, calculating a first impulse value by the processing unit 20, and outputting the first impulse value to an electronic device 30; wherein, the first impulse value is calculated by the following formula: l (CP2-CP1)/(t2-t 1).
As shown in fig. 6, after the processing unit 20 calculates the first clash value, the method further includes step S3: the processing unit 20 continuously receives the key pressing signal, records a third time t3 when the key pressing signal is smaller than the second reference CP2 and equal to the second reference CP2 again, records a fourth time t4 when the key pressing signal is equal to the first reference CP1, calculates a second type impulse value by the processing unit 20, and outputs the second type impulse value to the electronic device; wherein, the second impulse value is calculated by the following formula: l (CP1-CP2)/(t4-t 3).
Please refer to fig. 7, which is a detailed flowchart of the impulse-like button sensing method according to the present invention; as can be seen from the figure, when the user presses the key 10, the key pressing signal is continuously output to the processing unit 20, the processing unit 20 reads the key pressing signal and the current time, if the key pressing signal does not reach the first reference CP1, the receiving and reading are continuously performed, when the key pressing signal is equal to the first reference, the current time (i.e., the first time t1) is recorded at the same time, then the receiving and reading are continuously performed until the key pressing signal is equal to the second reference CP2, the current time (i.e., the second time t2) is recorded again, and the calculation of the first type impulse (i.e., the type impulse of the pressed key) can be performed and output to the electronic device 30; of course, the second reference CP2 is set to be greater than the maximum force point of the user, so that the key is still pressed after the key pressing signal is equal to the second reference CP2, so that the key pressing signal is less than the second reference CP 2; when the key-pressing signal reaches a maximum force-applying value, i.e., the key-releasing stroke of the key 10, and the key-pressing signal is equal to the second reference CP2 again, the processing unit 20 records the current time (i.e., the third time t3), continues to receive and read the key-pressing signal until the key-pressing signal is equal to the first reference CP1, records the current time (i.e., the fourth time t4) again, and calculates the second type of stroke value (i.e., the stroke value of the released key), and outputs the second type of stroke value to the electronic device 30.
As can be seen from the above description, the present invention utilizes the force and speed of the user pressing and releasing the key 10 to calculate the slope value change during the pressing and releasing process, and the change makes the electronic device 30 perform the corresponding program processing, so as to be further applicable to games, specific programs or software, and perform different effect processing according to the difference of the impact values, so that the user can operate the specific functions of the games, programs or software according to different forces and speeds, thereby achieving different levels of operation effects.
