Detailed Description

So that the manner in which the features and aspects of the present application can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

Fig. 1 is a schematic structural composition diagram of an input device according to an embodiment of the present application, as shown in fig. 1, the input device may specifically be an active stylus, and the input device includes: a body 100 and an input terminal 200, the input terminal 200 being connected to one end of the body 100. The body 100 is provided with a light emitting module (not shown), a light receiving module (not shown) and a light comparing module (not shown), wherein the light emitting module is used for emitting a first light signal; the optical receiving component is configured to receive a second optical signal, where the second optical signal is a signal formed after the first optical signal passes through the input end 200 of the input device. The optical comparison component is used for comparing the first optical signal with the second optical signal to obtain a comparison result; and determining the current state of the input device as the input state under the condition that the comparison result represents that the first optical signal and the second optical signal are inconsistent. Therefore, the input state of the input device can be accurately determined through the optical signal.

In this application, the body 100 is further provided with a power source (not shown in the figure), which is electrically connected to the light emitting module for supplying power to the light emitting module.

In this application, the input end 200 of the input device is provided with an optical fiber assembly 201, one end of the optical fiber assembly 201 is arranged at the light emitting position of the light emitting assembly, and the other end of the optical fiber assembly 201 is arranged at the light receiving position of the light receiving assembly. The first optical signal emitted by the light emitting component can be conducted through the optical fiber component 201, so that the body becomes a luminous body.

In the present application, when the fiber optic assembly 201 is not in contact with the writing medium 300, the first optical signal may be totally reflected multiple times during the conduction process of the fiber optic assembly 201; the first optical signal may be refracted during the propagation of the fiber optic assembly 201 when the fiber optic assembly 201 is in contact with the writing medium 300.

In this application, the second optical signal received by the optical receiving component is the signal conducted through the optical fiber component 201. The second optical signal may be a refracted signal or a totally reflected signal.

After the optical receiving component receives the second signal, the optical comparing component may be triggered to compare the second signal with the first signal to determine whether there is optical loss between the second signal and the first signal, so that when it is determined that there is optical loss between the second signal and the first signal, the current state of the input device is determined to be the input state, and conversely, when it is determined that there is no optical loss between the second signal and the first signal, the current state of the input device is determined to be the non-input state.

In this application, the light emission subassembly can also launch the first light signal of different colours, and the structure of optic fibre subassembly 201 can be based on the shape phase-match of input end 200 simultaneously to when conducting first light signal through optic fibre subassembly 201, can be so that each side of input end can both give out light, in order to improve the interest.

In this application, the optical fiber assembly 201 can be bent to form an elastic bending structure 202, the bending structure 202 can be an elastic circular structure, an elliptical structure, a U-shaped structure or a V-shaped structure, and the bending structure 202 is exposed outside the input end 200 for contacting the writing medium 300.

In this application, the input end 200 further includes: an electrical emission component (not shown in the figures) for sending an electrical signal to the electronic device where the writing medium 300 is located, so that the electronic device determines the display position of the input information according to the electrical signal.

Specifically, after the optical comparison component compares the first optical signal with the second optical signal, if the comparison result indicates that the first optical signal and the second optical signal are not consistent, the optical fiber component 201 is determined to be in contact with the writing medium 300, at this time, the optical comparison component triggers the electrical emission component, and the electrical emission component sends an electrical signal to the electronic device where the writing medium 300 is located under the condition that the optical fiber component 201 is determined to be in contact with the writing medium 300, so that the electronic device determines the display position of the input information according to the electrical signal.

In this application, the input end 200 further includes: a pressure sensor (not shown in the figure) for detecting the pressure applied to the bending structure 202 of the optical fiber assembly 201 to obtain a pressure parameter; and under the condition that the voltage sensor obtains the pressure parameter, triggering the electric emission assembly, and sending an electric signal to the electronic equipment where the writing medium is located by the electric emission assembly according to the pressure parameter.

In this application, the electrical emission component may specifically be configured to send different electrical signals to the electronic device where the writing medium is located according to the difference in the pressure parameter.

Here, the difference of the electrical signals means that parameters such as voltage, electrical frequency, current, and resistance corresponding to the electrical signals are different.

In the application, the pressure sensor can compare the pressure parameter with a preset pressure threshold value under the condition of obtaining the pressure parameter to obtain a comparison result, and when the comparison result represents that the pressure parameter is greater than the preset pressure threshold value, the pressure sensor triggers the power transmitting assembly to send an electric signal to the electronic equipment where the writing medium is located.

In this application, the electrical parameters of the electrical signal sent by the electrical emission assembly to the electronic device based on the pressure parameters are different than the electrical parameters of the electrical signal sent to the electronic device in which the writing medium 300 is located if the fiber optic assembly 201 is determined to be in contact with the writing medium 300.

For example, the electrical parameters of the electrical signals may be different, such as voltage, electrical frequency, current, resistance, etc.

In this manner, different electrical signals may be caused to display different effects of writing on a writing medium of an electronic device by sending different electrical signals to the electronic device. Such as thickness effect of writing, stroke effect of writing, etc., to meet different requirements of users.

In this application, the light emitting module may also stop emitting the first optical signal when it is determined that the bent structure 202 of the optical fiber module 201 is deformed under pressure. Thus, the power of the input device can be saved.

In the present application, the same condition of optical refractive index can be satisfied between the material of the optical fiber assembly 201 and the material of the writing medium 300.

This application utilizes light signal to trigger input device and sends input signal to the electronic equipment that writes the medium place to confirm input device's input state, not only can shorten the display stroke of the pen point that falls of the word that shows on writing the medium, but also can prolong the display stroke of the pen point that carries of the word that shows on writing the medium, make the word that shows have sharp, clear stroke.

For example, when a user writes a "down" word by using the pen of the present application, when the pen is in a "0" contact state with a writing medium, the pen of the present application may generate optical loss due to contact between the pen tip and a screen of the writing medium, and at this time, when the pen tip is in a "0" contact state with the writing medium, the pen of the present application may send an input signal to the electronic device where the writing medium is located, so that the electronic device where the writing medium is located determines a pen-down position of the "down" word according to the input signal at a corresponding position of the screen of the writing medium. The pen down positions of, for example, "down" words include: a start position of "" a left-falling "" thereby displaying a "down" character stroke-falling point at the determined stroke-falling position of the "down" character. For example, the pen down points of the "lower" word include: the starting point of "" one "", "|", and "" left-falling "". Therefore, the display stroke of the pen point of the lower character is shortened, and the displayed lower character has a clear pen point.

Here, the state in which the pen tip is in contact with the writing medium in the "0" state refers to a case in which the user does not apply any pressure to the writing medium by the pen, in other words, a state in which the pen is in contact with the writing medium in a zero pressure state.

When a user writes a 'down' word by using a pen in the prior art, when the pen is in a '0' contact state with a writing medium, an input signal is not sent to the electronic device where the writing medium is located, so that the electronic device where the writing medium is located cannot determine the pen-down position of the 'down' word when the pen is in the '0' contact state with the writing medium, and the pen-down point of the 'down' word cannot be displayed when the pen is in the '0' contact state with the writing medium. In the prior art, only when the pen point is in contact with the writing medium, pressure is applied to the writing medium, and the pressure value is greater than a certain threshold value, the pen is triggered to send an input signal to the electronic device, and the electronic device where the writing medium is located can determine the pen-down position of the 'down' character according to the pressure value corresponding to the pressure, so that the pen-down point of the 'down' character is displayed at the pen-down position.

Compared with the existing pen, the pen can shorten the stroke of the pen falling point of the displayed character, and can also enable the displayed character to have clear and sharp pen points, so that the display precision of the character is improved.

The pen sends the input signal to the electronic equipment where the writing medium is located when the pen point and the writing medium are in a '0' contact state, and the electronic equipment where the writing medium is located can also determine the pen lifting position of the display information according to the input signal, so that the pen lifting point of the display information is displayed at the pen lifting position.

Continuing with the above example, during writing a "down" word with the pen of the present application, when the pen is in a "0" contact state with the writing medium, the pen of the present application may generate optical loss due to the contact of the pen tip with the screen of the writing medium, and at this time, when the pen tip is in a "0" contact state with the writing medium, the pen of the present application may send an input signal to the electronic device where the writing medium is located, so that the electronic device where the writing medium is located determines the pen-up position of the "down" word according to the input signal at the screen-corresponding position of the writing medium. Pen-up positions such as "down" include: an end position of "" a left-falling stroke "" thereby displaying a "lower" character stroke-raising point at the determined stroke-raising position of the "lower" character. For example, the "lower" stroke points include: an end point of "" one "" an end point of "" left-falling "". That is, according to the pen provided in the present application, the point at which the pen tip is in contact with the writing medium "0" is the pen-up point of the displayed word. Therefore, the display stroke of the pen lifting point of the lower character is prolonged, and the displayed lower character has a clear pen point.

In the process of writing the 'down' character by using the pen in the prior art, the user does not send an input signal to the electronic equipment where the writing medium is located when the pen is in the '0' contact state with the writing medium, so that the electronic equipment where the writing medium is located cannot determine the pen lifting position of the 'down' character when the pen is in the '0' contact state with the writing medium, and the pen lifting point of the 'down' character cannot be displayed when the pen is in the '0' contact state with the writing medium. In the prior art, only when the pen point does not apply pressure to the writing medium any more or the pressure value is smaller than a certain threshold value, the pen stops sending the input signal to the electronic device, and the electronic device where the writing medium is located also determines the pen lifting position of the lower character according to the pressure value corresponding to the pressure, so that the pen lifting point of the lower character is displayed at the pen lifting position. That is, based on the existing pen, the pressure point when the pressure value is smaller than a certain threshold value is the pen-up point of the displayed word.

Compared with the existing pen, the pen can prolong the stroke of the pen lifting point of the displayed character, and can also enable the displayed character to have clear and sharp pen points, so that the display precision of the character is improved.

Fig. 2 is a schematic flow chart of an implementation of the input method in the present application, and as shown in fig. 2, the input method includes:

step 201, transmitting a first optical signal through an optical transmitting component, and receiving a second optical signal through an optical receiving component, where the second optical signal is a signal formed by the first optical signal after total reflection or refraction;

the input method provided in the present application is mainly applied to an input device, for example, the input device may be an active stylus. The input device comprises a light emitting component, a light receiving component and a fiber-optic component.

In this application, a first optical signal transmitted by the optical transmission module may be optically transmitted through the optical fiber module, and a second optical signal transmitted through the optical fiber module may be received by the optical reception module.

In the present application, the optical fiber assembly may be in contact with a writing medium, and when the optical fiber assembly is not in contact with the writing medium, the first optical signal may be totally reflected multiple times during the conduction of the optical fiber assembly; the first optical signal may be refracted during propagation of the fiber optic assembly when the fiber optic assembly is in contact with a writing medium.

Step 202, comparing the first optical signal and the second optical signal;

in this application, the input device is further provided with an optical comparison module, and after the second optical signal is received by the optical receiving module, the optical comparison module may compare the first optical signal with the second optical signal to determine whether the second optical signal generates optical loss according to the comparison result, so as to determine the contact state of the input device and the writing medium according to the optical loss.

Step 203, determining that the current state of the input device is the input state under the condition that the first optical signal and the second optical signal are not consistent according to the comparison result.

In this application, when the optical comparison component determines that the first optical signal and the second optical signal are not consistent according to the comparison result, it is indicated that the second optical signal has optical loss, and it indicates that the input device is currently in a 0-contact state with the writing medium, and then it is determined that the current state of the input device is the input state.

In this application, the input device further includes a light emitting component, and when the light comparing component determines that the current state of the input device is the input state, the light emitting component may be triggered to send an electrical signal to the electronic device where the writing medium is located through the light emitting component, so that the electronic device determines the display position of the input information according to the electrical signal.

Through the input method provided by the application, the optical signal can be used for controlling the input device to send the electric signal to the electronic device where the writing medium is located, namely, the input state of the input device can be controlled through the optical signal, so that the display stroke of the pen-down point of the displayed character can be shortened, the display stroke of the pen-up point of the displayed character can be lengthened, and the displayed character has a sharper and clear pen point. Without being as virtual as the nib of a word written by a prior art pen.

In the application, the electronic device where the writing medium is located may further obtain all capacitance values between the pen falling point and the first pressure point of each stroke, or obtain all capacitance values between the last pressure point and the pen lifting point of each stroke, perform fitting curve processing on all capacitance values to obtain all processed capacitance values, and then determine whether all processed capacitance values belong to a 0 value or a preset value. Therefore, when the value of the stroke belongs to 0, a thinner stroke is displayed, and when the value of the stroke belongs to a preset value, a thicker stroke is displayed.

Specifically, the determining whether all the processed capacitance values belong to 0 values or preset values includes:

and taking the intermediate value between the 0 value and the preset value as a reference value, and then respectively comparing all the processed capacitance values with the reference value to obtain a comparison result. Classifying the capacitance values larger than the reference value into a preset value group according to the comparison result, classifying the capacitance values smaller than the reference value into a 0 value group, then comparing the capacitance values of the preset value group and the 0 value group, if the capacitance values of the preset value group are larger than the capacitance values of the 0 value group, determining that all the processed capacitance values belong to the preset values, and the shape of the displayed pen front can be changed from thin to thick, and if the capacitance values of the preset value group are smaller than the capacitance values of the 0 value group, determining that all the processed capacitance values belong to the 0 value, and the shape of the displayed pen front can be changed from thick to thin, as shown in fig. 3 specifically.

Fig. 3 is a schematic diagram of a word written by using the pen in the present application, as shown in fig. 3, the written word is a "one" word, and the "one" word includes a tip 31 and a tip 32, wherein the tip 31 is a writing end of the "one" word, and the shape of the tip 31 is gradually changed from thin to thick from a point a to a point B. The tip 32 is a straight-line-shaped pen-lifting end, and the shape of the tip 32 gradually changes from thick to thin from point C to point D. Therefore, the displayed characters have sharper and clear stroke edges, and are not as virtual as the stroke edges of the characters written by the prior art pen.
