Description
Technical Field
The invention relates to a touch screen technology, in particular to a method and a device for realizing zero touch height.
Background
As shown in fig. 1, in the existing infrared touch screen, an infrared transmitting/receiving pair tube form is adopted as an information transmission carrier, and lamp body designs of the infrared pair tubes adopting the form have a certain height, so that an optical network for signal transmission formed by infrared light has a certain height relative to a glass screen of the touch screen. When writing, in the process that the touch object enters the touch frame, the touch object firstly touches the plane of the infrared optical network and then only touches the glass plane of the screen. When the touch object touches the optical network plane, the transmission of infrared light rays can be blocked, at the moment, the information processing circuit of the touch frame can judge that a touch point is generated and respond, but at the moment, the touch object does not touch the real writing plane, so that poor writing experience can be caused. The effect is more obvious when the pen is used for writing with a pen. Conventionally, the height from the effective height to the surface of the glass screen when touching is defined as the touch height of the infrared touch screen.
Disclosure of Invention
The embodiment of the invention aims to provide a method and a device for realizing zero touch height, which can effectively solve the problem that the touch height in the current touch screen writing technology influences the writing experience and realize that the touch screen responds when in real contact.
In order to achieve the above object, an embodiment of the present invention provides a method for implementing a zero touch height, including:
scanning at a preset period through an infrared transmitting tube and an infrared receiving tube;
if any moment is from scanning no touch point to scanning touch point generated by any touch object, judging whether any moment receives pressure sensing data sent by the touch object;
if the pressure data is received, identifying the touch object as an intelligent pen, and entering an intelligent pen writing mode; the writing mode of the intelligent pen is to generate and display a writing track of the intelligent pen according to the pressure-sensitive data and the touch point coordinates acquired in real time.
Compared with the prior art, the method for realizing the zero touch height judges whether any time receives pressure-sensitive data sent by a touch object or not when the touch object generates the touch point from scanning the no touch point to scanning the any touch object at any time under the state that the touch point is not scanned, and identifies that the touch object is an intelligent pen and the intelligent pen is in mutual contact with a touch screen when the pressure-sensitive data is received, and enters an intelligent pen writing mode from any time; the writing mode of the intelligent pen is to display the writing track of the intelligent pen according to the pressure-sensitive data and the touch point coordinates acquired in real time. By adopting the scheme, when pressure-sensitive data sent by the intelligent pen are received, the touch-sensitive data are contacted with the touch screen, the touch point coordinates are uploaded on the glass surface of the touch screen, so that the problem that the touch object is shielded by an infrared signal to display the touch-sensitive data is solved, zero touch height can be realized, the problem that the infrared sensing area entering the touch screen is not contacted with the glass surface of the touch screen is displayed to generate touch height can be avoided, the experience of writing on paper by the pen can be simulated, and the intelligent touch-sensitive touch screen is more intelligent.

In the steps, whether the pressure data exist at two continuous moments or not is judged, so that the touch object is effectively identified, and the condition of misjudgment is avoided.
As an improvement of the scheme, the method further comprises the following steps:
if the pressure data is judged not to be received at any moment, caching the coordinates of the touch points scanned at any moment;
if the touch point generated by the touch object is not scanned at the next moment of any moment, eliminating the coordinate of the touch point scanned at any moment in the cache;
and if the pressure data is judged not to be received at the next moment of any moment, displaying the coordinates of the touch point scanned at any moment in the cache, and then entering the conventional writing mode.

The continuous writing function of the intelligent pen can be realized through the step, the problem that the coordinate of the touch point is still sensed to display when slight disconnection occurs between the strokes in the writing process is avoided, and the experience of writing on paper by the pen is better simulated.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2, a schematic flow chart of a method for implementing zero touch height according to embodiment 1 of the present invention includes:
s1, scanning through the infrared transmitting tube and the infrared receiving tube in a preset period;
s2, if any time is from scanning no touch point to scanning touch point generated by any touch object, judging whether any time receives pressure data sent by the touch object;
s3, if the pressure data are received, identifying the touch object as an intelligent pen, and entering an intelligent pen writing mode; the writing mode of the intelligent pen is to generate and display a writing track of the intelligent pen according to the pressure-sensitive data and the touch point coordinates acquired in real time.
It will be appreciated that the pressure data is generated by a pressure sensor mounted on the smart pen and transmitted by a wireless module mounted on the smart pen. Preferably, the sensing module is a pressure sensor.
In a specific implementation, in a state where no touch point is scanned, if a touch point generated by any touch object is scanned at any time from a non-touch point to a touch point generated by any touch object, the any time is a time corresponding to a scanning cycle, for example, scanning is performed with T as a cycle, and when T1-T does not scan a touch point and T1 scans a touch point generated by any touch object, T1 meets the requirement of "any time". Judging whether the pressure-sensitive data sent by the touch object is received at any moment, if so, identifying that the touch object is an intelligent pen and the intelligent pen is in mutual contact with the touch screen, and entering an intelligent pen writing mode from any moment; the writing mode of the intelligent pen is to display the writing track of the intelligent pen according to the pressure-sensitive data and the touch point coordinates acquired in real time. By adopting the scheme, the trace that the intelligent pen writes can be displayed when pressure-sensitive data sent by the intelligent pen is received, so that the problem that the touch object is shielded by an infrared signal to display is avoided, zero touch height can be realized, the problem that the infrared induction area entering the touch screen displays the touch height can not occur, the experience that the pen writes on paper can be simulated, and the intelligent touch pen is more intelligent.
Referring to fig. 3, which is a schematic flow chart of a method for implementing zero touch height according to embodiment 2 of the present invention, embodiment 2 further includes, on the basis of embodiment 1, the steps of:
s4, if the pressure data is not received at any moment, judging whether a touch point generated by the touch object is scanned at the next moment of any moment when the next moment of any moment is reached;
s5, if the touch point generated by the touch object is scanned at the next moment of any moment, judging whether the pressure data sent by the touch object is received at the next moment of any moment;
s6, if the pressure data is received at the next moment of any moment, identifying the touch object as an intelligent pen, and entering a writing mode of the intelligent pen; if the pressure data is judged not to be received at the next moment of any moment, identifying the touch object as a conventional touch object, and entering a conventional writing mode; the conventional touch object is other touch objects except the intelligent pen; and the conventional writing mode is to generate and display a track written by the conventional touch object according to the touch point coordinates acquired in real time.
In one embodiment, each scan generates a frame of data, and each frame of data includes a storage space for coordinate data and pressure data. If the first frame data obtained at any time includes coordinate data but does not include pressure-sensitive data, detecting whether second frame data formed at the next time of the any time includes pressure-sensitive data; if the next moment of any moment includes the coordinate data but does not include the pressure-sensitive data, the touch object is considered to be a conventional touch object and enters a conventional writing mode. The conventional touch object is other touch objects outside the intelligent pen, the conventional touch object is not provided with an induction module for generating pressure-sensitive data and a wireless module for sending the pressure-sensitive data, and the conventional writing mode is to display a writing track of the conventional touch object according to touch point coordinates acquired in real time. And if the next moment of any moment comprises the coordinate data and the pressure data, the touch object is considered to be the intelligent pen, and the intelligent pen writing mode is entered. By detecting the coordinate data and the pressure data at two continuous moments, the conventional touch object and the intelligent pen can be effectively identified. Because the smart pen enters when the first frame of the touch screen is about to be scanned, and when the scanning of the first frame is finished, the smart pen is in a entering state, that is, the smart pen does not reach the glass plane of the touch screen yet, but the smart pen is within the identification height of the infrared touch frame, no pressure data is generated at this time, and a misjudgment situation occurs, the data frames obtained at two consecutive times (that is, at any time and the next time of any time) are required to be combined and judged to obtain an accurate result. When the touch object is identified to be a conventional touch object, because pressure data cannot be obtained, a display response cannot be made according to whether the touch object is in contact with the touch screen, and therefore the zero touch height cannot be realized in the writing process of the conventional touch object. When the conventional touch object enters the plane of the infrared optical network and does not touch the glass plane of the screen, the transmission of infrared light is blocked, so that a touch point is judged to be generated, the touch point is uploaded to be displayed at the moment, and the writing process is identified as the conventional touch object.
Referring to fig. 4, which is a schematic flow chart of a method for implementing zero touch height according to embodiment 3 of the present invention, embodiment 3 further includes, on the basis of embodiment 2, the steps of:
s7, if the pressure data are judged not to be received at any moment, caching the coordinates of the touch points scanned at any moment;
s8, if the touch point generated by the touch object is not scanned at the next moment of any moment, eliminating the touch point coordinate scanned at any moment in the cache;
and S9, if the pressure data is judged not to be received at the next moment, displaying the coordinates of the touch point scanned at any moment in the cache, and then entering the conventional writing mode.
According to the scheme, the touch object can be judged to be the conventional touch object from the next moment of any moment, and if the scanned touch point coordinate of any moment is not cached, the situation that the touch point coordinate of any moment is lost and cannot be displayed is caused, so that the writing rule of the conventional touch object is obviously violated. Therefore, if the pressure data is not received at any moment, caching the coordinates of the touch points scanned at any moment; if the touch point generated by the touch object is not scanned at the next moment of any moment, the coordinates of the touch point scanned at any moment in the cache are cleared, so that the touch object is not written but is touched by mistake, the coordinates of the touch point scanned at any moment are not required to be displayed, and the cache can be cleared; and if the pressure data is judged not to be received at the next moment of any moment, displaying the coordinates of the touch point scanned at any moment in the cache, and then entering the conventional writing mode, so that the response rule of a conventional touch object is better met.
Referring to fig. 5, which is a schematic flow chart of a method for implementing zero touch height according to embodiment 4 of the present invention, embodiment 4 further includes, on the basis of embodiment 1, the steps of:
s10, in the writing mode of the intelligent pen, if the touch point generated by the intelligent pen is scanned at any time and the pressure data sent by the intelligent pen is not received, determining that the intelligent pen is in a lifting state; when the intelligent pen is in a lifted state, the writing track of the intelligent pen is not displayed;
s11, in the writing mode of the intelligent pen, if the touch point generated by the intelligent pen is not scanned at any time, exiting the writing mode of the intelligent pen;
and S12, in the normal writing mode, if the touch point generated by the intelligent pen is not scanned at any time, exiting the normal writing mode.
The steps provide a processing mode of multiple conditions in the intelligent pen writing mode and the conventional writing mode so as to realize a smoother writing process. In the writing mode of the intelligent pen, if a touch point generated by the intelligent pen is scanned at any time and pressure data sent by the intelligent pen is not received, the intelligent pen is determined to be in a lifting state; when the intelligent pen is in a lifted state, the writing track of the intelligent pen is not displayed; when the intelligent pen is in a lifted state, but the coordinate data can still be scanned, the intelligent pen does not need to be identified again, the writing mode of the intelligent pen does not need to be exited, and the scanned coordinate data is not uploaded for display. Through the scheme, continuous writing of the intelligent pen can be realized, namely, a pen point is slightly lifted in the writing process, handwriting is changed from thick to thin, a writing mode of short disconnection exists between different strokes, the simulation of writing of the pen on paper is realized, even if short lifting exists between the strokes, and the lifted height is located in the scanning infrared red net range, the passing track of the intelligent pen between the strokes can not be displayed. In addition, in the writing mode of the intelligent pen or the conventional writing mode, if the touch point generated by the intelligent pen is not scanned at any time, the writing mode of the intelligent pen or the conventional writing mode exits, the state that the touch point is not scanned is returned, and when the intelligent pen or the conventional touch object writes again, the intelligent pen or the conventional touch object needs to be re-identified and then enters the corresponding writing mode respectively.
