Background
A touch pad (TouchPad or TrackPad) is an input device widely used in notebook computers, and controls the movement of a pointer by sensing the movement of a user's finger. The touch pad may be considered as an alternative to the mouse. Touchpads are also found on other portable devices, such as personal digital assistants and some portable audio-visual devices. Subject to design constraints, touchpads are typically no larger than 20 square centimeters for display screen zoom in and out gestures (gestures), and handwriting input applications. The touch panel is made into an array of rows and columns by a printed circuit board; the printed board and the surface plastic film are adhered by strong double-sided adhesive tape, and the sensing principle is capacitance sensing. A special integrated circuit board under the touch pad surface constantly measures and reports this trace to ascertain finger motion and position.
A touch panel is an input terminal that can move a cursor by a sliding operation of a finger on a smooth touch panel. Can be easily used by beginners. Because the thickness of the touch panel is very thin. So that the keyboard can be designed in a ultrathin notebook computer or a keyboard. And is not a mechanical design. It is very simple and convenient in maintenance. The operating principle is that when the finger of the user approaches the touch pad, the capacitance will be changed, and the control IC of the touch pad will detect the capacitance change and convert it into coordinates. The touch pad learns the finger movement condition by capacitance induction and is insensitive to finger heat. When a finger touches the board surface, the electrostatic field on the board surface changes. The touchpad sensor is simply a conductive line of finger traces printed on the surface of the board.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the touch panel control method based on the infrared blood flow detection sensor according to the preferred embodiment of the present invention includes the following steps:
and step S10, adding an infrared blood flow detection sensor at the switch position of the touch pad in advance, wherein the infrared blood flow detection sensor is used for identifying a blood flow signal when a human hand touches the touch pad, so that the touch pad switch can be triggered accurately.
Specifically, an infrared blood flow detection sensor is added to the switch position of the touch panel in advance, the number of the infrared blood flow detection sensors added to the switch position of the touch panel is one or more, for example, 1 or 4, the infrared blood flow detection sensors can be placed at any position such as corners or middle of the touch panel, for example, when 1 infrared blood flow detection sensor is added to the switch position of the touch panel, the infrared blood flow detection sensor can be placed at the most middle position of the touch panel, and when 4 infrared blood flow detection sensors are added to the switch position of the touch panel, the 4 infrared blood flow detection sensors can be placed at the four corners of the touch panel, for example, at the four corners, and one infrared blood flow detection sensor is placed at each corner, and the sensors are placed symmetrically.
The infrared blood flow detection sensor is used for identifying a blood flow signal when a human hand touches the blood flow detection sensor so as to accurately trigger the touch pad switch and avoid false triggering.
And step S20, when the finger is detected to touch the switch position of the touch pad, the infrared blood flow detection sensor detects a finger blood flow signal.
Specifically, when a finger is detected to touch the switch position of the touch pad, the infrared blood flow detection sensor arranged at the switch position detects a finger blood flow signal, and further, a third preset time for placing the mobile phone at the switch position of the touch pad is preset, and the third preset time can be set by a user through software according to requirements, so that the third preset time can be freely set according to user habits, for example, the third preset time is 3 seconds; if the time that the finger of the user is placed at the switch position of the touch pad is shorter than the third preset time, which indicates that the touch time is too short and the user may touch the touch pad by mistake, the current operation is directly finished without judging whether the current operation is manual operation, namely, the step S30 is not continuously executed; if the time for placing the finger of the user on the switch position of the touch pad is not less than the third preset time, for example, the placing time is 3 seconds or 5 seconds, determining whether the current operation is a manual operation, namely, continuing to execute step S30; the arrangement can prevent the touch pad function from being started by the mistaken touch of the finger of the user.
And step S30, the infrared blood flow detection sensor judges whether the finger is operated by hand according to the finger blood flow signal and the touch time.
Specifically, the infrared blood flow detection sensor arranged at the switch position of the touch pad judges whether the finger is operated by hand according to the finger blood flow signal and the touch time, and if the finger is operated by hand, the step S40 is continuously executed; and if the infrared blood flow detection sensor judges that the operation is not manual operation according to the finger blood flow signal and the touch time, controlling the function of the touch pad not to be started, and avoiding mistakenly starting the function of the touch pad.
And step S40, if the current operation of the user is judged to be manual operation, the function of the touch pad is opened for the user to normally use the touch pad.
Specifically, if the current operation of the user is determined to be a manual operation, that is, the current touch operation is determined to be an operation of the user by a finger through the infrared blood flow detection sensor, and not other operations (for example, metal touch and the like), the touch panel function of the touch panel is turned on, so that the user can normally use the touch panel.
Further, after the step S40, the method further includes: and when the time for touching the position of the switch after the user finishes using the touch pad exceeds a first preset time or exceeds a second preset time and the touch pad is not used, controlling the function of the touch pad to be closed. Namely, when the user touches the switch position for a long time after using the touch panel or does not use the touch panel for a long time, the system judges that the touch panel is not needed to be used and closes the function of the touch panel. The first preset time and the second preset time are preset through software according to the requirements of users, the first preset time and the second preset time are the same or different, namely the time of automatic closing when the automatic closing device is not used for a long time can be set according to the user requirement software, and the time of manual long-time closing by the users can also be set according to the user requirement software.
In the invention, the touch panel is a resistance type touch panel or a capacitance type touch panel. When a finger touches the switch position, the infrared blood flow detection sensor detects a blood flow signal of the finger and judges that the finger operates by hand according to the touch time and turns on the function of the touch pad, a user can normally use the touch pad, and when the user touches the switch position for a long time after using the touch pad or does not use the touch pad for a long time, the system judges that the touch pad does not need to be used and turns off the function of the touch pad.
