Description
Technical Field
The invention relates to the technical field of touch screens, in particular to an interaction control method based on a touch screen.
Background
At the present stage, mobile terminals such as smart phones, tablet computers, personal digital assistants, and the like, which are electronic consumer products necessary for people's life, have been integrated into various aspects of life, and with the development of touch screen technology, the traditional operation mode by keys gradually changes to the touch interaction direction, and more mobile terminals enable virtual keys to replace physical keys.
The interactive control mode refers to the implementation mode of the control logic of the switching system. Two main categories are distinguished: the direct control is mainly used for step system, the control components are dispersed in all levels of machine keys, and the actions of the machine keys are directly controlled by the dialing pulse of a user. Indirect control, the special equipment receives the user dialing, and the action of the exchange network is controlled after the user dialing is analyzed by the control equipment. The flexibility of indirect control is high, and the method is used for crossbar and stored program control switches. The control equipment in the cross-bar system is relatively centralized and consists of a register and a marker. The control equipment of the program controlled exchanger is a processor and can be divided into different control structures such as centralized control, hierarchical decentralized control and distributed decentralized control.
With the continuous development of multimedia technology, touch screens are increasingly used as a new input device in various devices. The touch screen has the advantages of high response speed, space saving, easy communication and the like. The user can operate the equipment by lightly touching the icons or characters on the touch screen with fingers, so that the man-machine interaction is more straightforward.
In recent years, with the development of high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, electronic devices in which a light-transmissive touch panel is mounted on the front surface of a display device such as a liquid crystal display have been increasing. A user of such an electronic device operates the touch panel by pressing the touch panel with a finger, a stylus, or the like while visually checking the display content of the display device located on the back surface of the touch panel. Thereby, various functions of the electronic apparatus can be operated.
According to the working principle of the touch screen and the difference of transmission media, the existing touch screen is divided into four types, namely a resistance type, a capacitance type, an infrared type and a surface acoustic wave type. The capacitive touch screen is widely applied due to high sensitivity and low required touch force.
The touch screen is also called as touch screen or touch panel, and is an inductive liquid crystal display device capable of receiving input signals of a touch head and the like, when a graphical button on the screen is touched, a touch feedback system on the screen can drive various connecting devices according to a pre-programmed program, so that the touch screen can be used for replacing a mechanical button panel, and vivid video and audio effects can be produced by a liquid crystal display picture.
As a latest computer input device, the touch screen is a simple, convenient and natural man-machine interaction mode. The multimedia interactive device gives the multimedia a brand-new appearance and is a brand-new multimedia interactive device with great attractiveness. The method is mainly applied to inquiry of public information, industrial control, military command, electronic games, multimedia teaching and the like.
Gradually, the easiest man-machine interaction technology has been introduced into many fields, and is widely applied to home appliances, public information (e.g., business inquiry in departments such as e-government affairs, banks, hospitals, electric power, etc.), electronic games, communication equipment, office automation equipment, information collection equipment, industrial equipment, and the like, in addition to personal portable information products. Although the application of the touch screen technology in China is only over ten years, the touch screen technology becomes the most accepted computer input mode for common people after keyboard, mouse, handwriting pad and voice input. By using the technology, the user can operate the host machine by only lightly touching the icons or the characters on the computer display screen by fingers, so that the human-computer interaction is more straightforward. The technology is greatly convenient for users and becomes a brand new multimedia interaction device with great attraction.
Touch screens are broadly classified into four types, infrared type, resistive type, surface acoustic wave type, and capacitive type touch screens, according to the type of sensor. The infrared technology touch screen is low in price, but the outer frame of the touch screen is fragile and easy to generate light interference and distortion under the condition of a curved surface; the capacitive touch screen has reasonable design concept, but the problem of image distortion is difficult to solve fundamentally; the resistive touch screen is accurate in positioning, but the price is quite high and the resistive touch screen is afraid of scratching and is easy to damage; the surface acoustic wave touch screen overcomes various defects of the traditional touch screen, is clear and not easy to damage, is suitable for various occasions, and has the defect that if water drops and dust exist on the surface of the screen, the touch screen becomes dull or even does not work.
Infrared touch screen
The infrared touch screen is provided with a circuit board outer frame in front of the display, and the circuit board is provided with infrared transmitting tubes and infrared receiving tubes on four sides of the screen, and the infrared transmitting tubes and the infrared receiving tubes are in one-to-one correspondence to form a transverse and vertical crossed infrared matrix. When a user touches the screen, two infrared rays in the transverse direction and the vertical direction passing through the position can be blocked by fingers, so that the position of a touch point on the screen can be judged. Any touching object can change the infrared ray on the touch point to realize the touch screen operation.
The infrared touch screen is free from current, voltage and static interference and is suitable for certain severe environmental conditions. Its main advantages are low cost, easy installation, and no need of card or any other controller. In addition, because no capacitance charging and discharging process exists, the response speed is higher than that of a capacitance type, but the resolution is lower.
Resistance type touch screen
The outermost layer of the resistance screen is generally a soft screen, and the inner contacts are connected up and down through pressing. The inner layer is filled with a physical material of metal oxide, namely an N-type oxide semiconductor, namely Indium Tin Oxide (ITO), also called indium oxide, the light transmittance of the inner layer is 80%, and the upper layer and the lower layer are spaced. The ITO is a main material used for both the resistance touch screen and the capacitance touch screen, the working surfaces of the ITO and the resistance touch screen are ITO coatings, the outer layer is pressed by fingertips or any object, the surface film is inwards concave and deformed, and the inner two layers of ITO are contacted with each other to be conductive, so that the coordinates of the pressed points are positioned to realize control. The screen has 4 lines, 5 lines and a plurality of lines according to the number of the lead-out lines of the screen, and has the advantages of low threshold, relatively low cost and no influence of dust, temperature and humidity. The disadvantage is also evident in that the outer screen is easily scratched and does not allow the use of sharp objects to touch the screen. Generally, multi-touch cannot be realized, that is, only a single point can be supported, and if two or more touch points are pressed simultaneously, accurate coordinates cannot be recognized and found. When a picture is to be amplified on the resistive screen, the user can only click the "+" for multiple times, so that the picture is amplified step by step in a stepwise manner, which is the basic technical principle of the resistive screen.
And pressure induction is utilized for control. When a finger touches the screen, the two conductive layers are in contact at the position of the touch point, and the resistance changes. Signals are generated in both the X and Y directions and then transmitted to the touch screen controller. The controller detects the contact and calculates the position of (X, Y), and then operates according to the mode of simulating the mouse. The resistance-type touch screen is not affected by dust, water and dirt and can work in severe environment. However, the outer layer of the composite film is made of plastic materials, so that the anti-explosion performance is poor, and the service life is influenced to a certain extent.
The resistance-type touch screen is controlled by pressure induction, the surface layer of the resistance-type touch screen is a layer of plastic, the bottom layer of the resistance-type touch screen is a layer of glass, the resistance-type touch screen can bear the interference of severe environment factors, but the hand feeling and the light transmission are poor, and the resistance-type touch screen is suitable for wearing gloves and occasions which can not be directly touched by hands.
Surface acoustic wave touch screen
A surface acoustic wave is a mechanical wave that propagates along the surface of a medium. The corners of the touch screen are provided with ultrasonic transducers. A high frequency sound wave can be transmitted across the screen surface and when a finger touches the screen, the sound wave at the touch point is blocked, thereby determining the coordinate position.
The surface acoustic wave touch screen is not influenced by environmental factors such as temperature, humidity and the like, has high resolution, scratch resistance, long service life and high light transmittance, can keep clear and transparent image quality, and is most suitable for public places. However, dust, water and dirt can seriously affect the performance of the panels and require frequent maintenance to maintain the smoothness of the panels.
Capacitive touch screen
The touch screen works by utilizing current induction of a human body, a layer of transparent special metal conductive substance is pasted on the surface of glass, and when a conductive object touches the touch screen, the capacitance of a contact point can be changed, so that the touched position can be detected. But does not react to touch with a gloved hand or a hand-held non-conductive object because of the addition of a more insulating medium.
The capacitive touch screen can well sense slight and quick touch, prevent scraping, is not afraid of dust, water and dirt influence, and is suitable for being used under severe environment. However, the capacitance varies with temperature, humidity or environmental electric field, so that the stability is poor, the resolution is low and the drift is easy.
With the development of information processing technology, human-computer interaction becomes a research hotspot of artificial intelligence technology. The large-screen interactive device frees the user from the constraint of a keyboard and a mouse, so that the user can directly control the computer on the touch screen of the interactive device, the interaction between people and the computer becomes more direct, but the large-screen interactive device is widely applied in the field of education, and the large-screen interactive device gradually replaces the traditional multimedia technology depending on the operation of the mouse and the keyboard.
From the technical principle, the touch screen is a set of transparent absolute coordinate positioning system, and firstly, the touch screen must be transparent, so that the problem of transparency must be solved by material technology, such as a digitizer, a writing board and an elevator switch, which are not touch screens; secondly, the device is absolute coordinates, a finger is touched and is the same, a second action is not needed, the device is not a mouse and is a set of relative positioning system, people can notice that touch screen software does not need a cursor, the cursor is reversed to influence the attention of a user, the cursor is used for relative positioning equipment, the relative positioning equipment needs to be moved to a place to firstly know where the cursor is and go to which direction, and the current position of the user needs to be fed back ceaselessly at every moment so as not to cause deviation. These are not required for touch screens that take absolute coordinate positioning; and secondly, the touch action of the finger can be detected and the position of the finger can be judged.
Characteristic of transparency
Transparent, it directly affects the visual effect of the touch screen. Transparency has a problem of transparency, an infrared technology touch screen and a surface acoustic wave touch screen only separate a layer of pure glass, and the transparency is outstanding, other touch screens have good priority, and the transparency is 'transparent', in the touch screen industry, the touch screen is a very general concept, many touch screens are multilayer composite films, the visual effect of the touch screen is not enough by only using the transparency, and the touch screen at least comprises four characteristics: transparency, color distortion, reflectivity and clarity, and can be subdivided, such as reflectivity levels including specular reflectivity and diffractive reflectivity levels, but only to the extent that the diffractive reflectivity of the touch screen surface has not yet reached the CD disk, which are essentially sufficient for the user.
Because of the graph of transmittance and wavelength, the image seen by the touch screen inevitably generates color distortion with the original image, the static image sense is also only color distortion, the dynamic multimedia image sense is not comfortable, and the color distortion degree, namely the maximum color distortion degree of the graph is naturally as small as possible. The transparency in general can only be the average transparency of the drawing, of course the higher the better.
For example, a chinese patent (application number CN108304091A) relates to a touch screen control method, a touch screen control device, and a touch screen, where the touch screen control method includes: receiving configuration parameters issued by an application program; determining a touch effective area according to the configuration parameters; detecting point reporting information corresponding to a touch action on the touch screen, wherein the point reporting information comprises a point reporting position; and responding to the touch action of the user when the touch point position is located in the touch effective area. By the touch screen control method, the touch area of the touch screen can be dynamically adjusted in the running process of the application program, the probability of misoperation of a user is reduced, the effective touch area on the touch screen can be flexibly determined according to the actual condition by the method, and the user experience is improved.
When a part of touch screens are used, a user may directly hold the screen with one hand, but in the operation process, the palm may contact with the surface of the touch screen, and even a middle finger, a forefinger and a ring finger all touch the surface of the touch screen, so that the subsequent touch control of the thumb cannot be smoothly performed, and even in the process of holding the screen, the palm, the middle finger, the forefinger and the ring finger touch the touch screen to cause misoperation, so that the whole operation process has obvious defects or even errors, and therefore an interactive control method based on the touch screen is needed to solve the problems.
