Problems solved by technology

The current touch sensor is completely overlapped with the display screen and has an integrated structure. Its advantage is that what you see is what you touch, and it is convenient for precise finger positioning. Bubbles and other requirements are particularly high, so the cost has been high; when keyboard input is required, the corresponding virtual keyboard must be displayed on the screen for positioning, so it occupies a certain display area and reduces the effective display area; fingers will be on the screen. Leaving fingerprints and oil stains, resulting in a decrease in display performance
Most keyboards and mice have the problems of large size, easy to get dirty, hard to clean, and inconvenient to operate. Therefore, new technologies of flat keyboard and flat mouse based on touch technology have appeared, but there are still problems of inconvenient use and space occupation.
However, the technology of collecting finger motions by using touch keyboard button sensing has low finger movement sensitivity and cannot accurately locate problems.

Embodiment 1

[0053] like figure 1 A human-machine input device based on multi-finger touch technology is shown, including a touch panel 1 , a touch signal microprocessor 2 , a gesture analysis module 3 and a communication module 4 .

[0054] The working method of the above-mentioned man-machine input device based on the multi-finger capacitive touch technology is as follows: the touch signal microprocessor 2 judges the corresponding position of the finger on the touch sensor panel through detection, and outputs to the gesture analysis module 3 through coding, including the touch hand. Index, corresponding touch coordinates and touch pressure and other information; Gesture analysis module 3 judges various touch gestures including each finger coordinate, moving direction and speed, finger click or double click, drag after clicking, and click virtual according to the aforementioned signals. Keys such as keyboard keys and multiple virtual keyboard combinations send information to the communica...

Embodiment 2

[0056] The structure of the touch panel 1 described in Implementation 1 is as follows: figure 2 , Figures 3a-3c As shown, it is composed of a protective panel 5 and a capacitive touch sensor 6. The capacitive touch sensor 6 includes an insulating plate 7 and a row scanning electrode 8 and a column scanning electrode 9 made on the insulating plate 7, and the row scanning electrode 8 and the column scanning electrode 9 is connected with the touch signal microprocessor 2, wherein the sensing area in the row scanning electrode 8 and the column scanning electrode 9 can be rhombus, as Figure 4 As shown, it can also be a straight line or a curved line; wherein the row scanning electrodes 8 and the column scanning electrodes 9 can be made on both sides of the insulating plate 7 respectively, or can be made on the same side of the insulating plate 7, and the intersection is through the conductive via hole 7a Connect or surface make insulating layer 7b by conducting bridge 7c and co...

Embodiment 3

[0059] like Image 6 As shown, the touch panel 1 in Embodiments 1 and 2 can be divided into an input area 1a and a functional area 1b; wherein the functional area 1b is located at the front end or both sides of the touch panel 1, and one or more keys or virtual keys 10 can be set , the virtual key can utilize the touch scanning area contained in the row and column scanning electrodes, and can also make independent sensing electrodes directly connected to the touch signal microprocessor 2 for special function keys such as power switch and volume adjustment and to control the touch response of the input area 1a. Switch between keyboard input, touch input, and other extended functions. When the finger selects the keyboard input in the functional area 1b, the gesture analysis module 3 finds the corresponding key value in the coordinate lookup table at the position of the finger in the control input area 1a; Key actions such as tapping and long pressing or key combination; at the ...

Abstract

The invention relates to an input device and an input method based on a multi-finger capacitive touch technology. The device is characterized by comprising a touch panel (1), a touch signal microprocessor (2), a gesture analysis module (3) and a communication module (4), wherein the touch panel (1) is used for receiving an input signal; the touch signal microprocessor (2) is used for receiving an output signal of the touch panel (1); the gesture analysis module (3) is used for analyzing the output signal of the touch signal microprocessor (2); and the communication module (4) is used for receiving the output signal of the gesture analysis module (3). The device and the method are convenient to use; and key input and coordinate positioning input can be obtained by moving both hands in a small movement range.

Description

technical field [0001] The invention relates to a human-machine input method and device, in particular to a computer, mobile phone, palmtop computer, electronic book or other artificial intelligence systems. Background technique [0002] Traditional handheld computers, mobile phones, and e-books mainly rely on keyboards for input, while computers, including desktop computers and portable notebook computers, mainly rely on keyboards and mice for man-machine communication. [0003] With the gradual maturity of multi-finger capacitive touch technology, human-machine input devices with touch control as the main body have been widely promoted and applied in intelligent systems including personal computers, palmtop computers, mobile phones, and e-books. Touch technology brings more and more convenient new operating experience to users. Various touch gestures make the communication between the operator and the intelligent system smoother and more in line with human action habits. ...
