The button includes electric capacity response module and infrared induction module, and wherein, electric capacity response module adopts capacitanc touch screen detection technique, and infrared induction module adopts infrared detection technique.
Referring to fig. 1, a flowchart illustrating steps of a key trigger detection method according to a first embodiment of the present invention is shown.
And step 110, acquiring a capacitance change value of the key and a first infrared intensity on the key.
Specifically, step 110 obtains a capacitance variation value of the key output by the capacitance sensing module. Specifically, step 110 obtains a first infrared intensity of the key outputted by the infrared sensing module.
And step 120, determining that the key is triggered under the condition that the capacitance change value is greater than a preset capacitance change threshold value and the first infrared ray intensity is greater than a preset infrared ray intensity threshold value.
The key is pressed under the condition that the capacitance change value is larger than a preset capacitance change threshold value, and the key is pressed by a body under the condition that the first infrared ray intensity is larger than a preset infrared ray intensity threshold value.
Specifically, the step 110 of obtaining the capacitance variation value of the key and obtaining the first infrared intensity on the key may be performed simultaneously, or the step 110 of obtaining the capacitance variation value of the key first and then obtaining the first infrared intensity on the key.
When the capacitance change value of the key is firstly obtained in the step 110 and then the first infrared ray intensity on the key is obtained, after the capacitance change value of the key is firstly obtained in the step 110, if the capacitance change value is greater than the preset capacitance change threshold value, the step 110 obtains the first infrared ray intensity on the key again, and if the first infrared ray intensity is greater than the preset infrared ray intensity threshold value, the step 120 determines that the key is triggered, so that the infrared sensing module does not need to be in a working state all the time, and the power consumption of the infrared sensing module can be reduced.
In the first embodiment of the present invention, the key is set to include a capacitance sensing module and an infrared sensing module, and the key is determined to be triggered by acquiring a capacitance change value of the key and a first infrared intensity on the key, where the capacitance change value is greater than a preset capacitance change threshold and the first infrared intensity is greater than a preset infrared intensity threshold, that is, when the key is pressed and a body presses the key. In the embodiment of the invention, the keys adopt the capacitance sensing module and the infrared sensing module, and the keys do not need to adopt solid keys, so that the electronic equipment has delicate appearance, good waterproof performance and long service life, and the keys are determined to be pressed only when being pressed and pressed by a body, so that the condition that the keys are mistakenly triggered by liquid or other electric conductors can be effectively reduced, and the experience of users in using the keys is improved.

The key comprises a capacitance sensing module and an infrared sensing module, wherein the capacitance sensing module adopts a capacitive touch screen detection technology, and the infrared sensing module adopts an infrared detection technology.
Referring to fig. 2, the key trigger detection method includes the following steps:
Specifically, the step 210 of acquiring the capacitance variation value of the key and acquiring the first infrared ray intensity on the key may be performed simultaneously.
Specifically, step 210 obtains a capacitance variation value of the key output by the capacitance sensing module. Specifically, step 210 obtains a first infrared intensity of the key output by the infrared sensing module.
Specifically, the infrared sensing module collects infrared rays on the key and determines first infrared ray intensity on the key according to the collected infrared rays.
Specifically, the capacitance sensing module detects a first capacitance value of the key before the key is pressed, detects a second capacitance value of the key when the key is pressed, and uses a difference value between the second capacitance value and the first capacitance value as a capacitance change value of the key.
The key is pressed under the condition that the capacitance change value is larger than a preset capacitance change threshold value, and the key is pressed by a body under the condition that the first infrared ray intensity is larger than a preset infrared ray intensity threshold value.
Optionally, the sensitivity of the key may be improved by decreasing the preset capacitance change threshold and/or the preset infrared intensity threshold, or may be decreased by increasing the preset capacitance change threshold and/or the preset infrared intensity threshold.

In step 222, it is determined that the key is triggered when the pressing speed is less than the preset speed threshold.
In general, when a certain part of the body contacts with the key at a higher speed, the key is touched by mistake, therefore, the pressing speed of the key is obtained in step 221, and when the pressing speed is smaller than a preset speed threshold, it indicates that the body contacts with the key at a low speed and is not in quick contact, and at this time, step 222 determines that the key is triggered by the finger, so that the occurrence of the situation that the body triggers the key by mistake can be effectively reduced, and the accuracy of detecting that the key is triggered is further improved.
Alternatively, the sensitivity of the key may be increased by increasing the preset speed threshold, or may be decreased by decreasing the preset speed threshold.
Optionally, in an embodiment of the present invention, the step 221 of obtaining the pressing speed of the key may include:
Specifically, step 223 may detect the infrared intensity at the preset distance on the key through the infrared sensing module, and when the infrared sensing module detects that the infrared intensity at the preset distance on the key is not equal to zero, step 223 determines that the infrared intensity at the preset distance on the key changes.
Specifically, the preset distance may be determined according to parameters such as a detection distance of the infrared sensing module and a trigger sensitivity of the key.
And step 225, determining the pressing speed of the key according to the first time, the second time and the preset distance.
Specifically, step 225 may calculate the pressing speed of the key according to the following calculation formula:
v＝△d/(t2-t1)
△ d is a predetermined distance, t2 is a second time, and t1 is a first time.
In the second embodiment of the present invention, the key is set to include a capacitance sensing module and an infrared sensing module, and the key is determined to be triggered by obtaining the capacitance change value of the key, the first infrared intensity on the key, and the pressing speed of the key, when the capacitance change value is greater than the preset capacitance change threshold, the first infrared intensity is greater than the preset infrared intensity threshold, and the pressing speed is less than the preset speed threshold, that is, when the key is pressed and a finger presses the key. In the embodiment of the invention, the keys adopt the capacitance sensing module and the infrared sensing module, and the keys do not need to adopt solid keys, so that the electronic equipment has delicate appearance, good waterproof performance and long service life, and the keys are determined to be triggered only when the keys are pressed and pressed by fingers, so that the condition that the keys are mistakenly triggered by liquid or other parts of a body except the fingers or other electric conductors can be effectively reduced, the sensitivity of the keys is convenient to improve (for example, the preset capacitance change threshold value and the preset infrared intensity threshold value are reduced, and the preset speed threshold value is increased), and the experience of users in using the keys is improved.
