Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display, and more particularly, to a display capable of converting handwritten contents into electronic data.

[0002]

2. Description of the Related Art Heretofore, what is used to display handwritten contents with a writing instrument or the like has been exclusively paper.

In recent years, computers and the Internet have become widespread, and it is assumed that they were developed in response to the growing need to convert handwritten characters, pictures, symbols, etc. into electronic data that can be handled by an information processing apparatus. For example, an input locus reading unit that includes an input unit such as a pen tip for handwriting input and an infrared irradiation unit that reads an input locus indicating the content handwritten by the pen tip by using infrared rays from the infrared irradiation unit. An input trajectory conversion means for converting the handwritten content read by the input trajectory reading means into electronic data; and an input trajectory data transmission for transmitting the input trajectory data converted into electronic data by the input trajectory conversion means to an external information processing device. A writable input device having means, and a writable surface to be written by the writable input device,
The special data on which the dot pattern is printed as a mark capable of providing the position information on the written surface to the input locus reading means on the written surface is used as an electronic data It is considered that the input locus data is transmitted to the external information processing device such as a personal computer by the input locus data transmitting means and is displayed on the display included in the information processing device. .

In addition, a pressure sensor or an electrostatic sensor is embedded in a display provided in the information processing device so that the handwritten content is displayed as electronic data and then displayed. Detects writing pressure and static electricity when handwriting with a so-called stylus type pen having a pen tip that does not have graphite or ink or fingers, and displays it on the display after converting it to electronic data Something like that is being considered.

[0005]

However, in the former case, the handwritten content can be converted into electronic data, but the written content is instantly displayed on a sheet of paper. Of course, there is no function to update the written contents only by displaying the written contents, and when trying to redisplay the input trajectory data corresponding to the handwritten contents converted into electronic data in the writing type input device, The input locus data must be transmitted to the external information processing device such as a personal computer by the input locus data transmitting means and displayed on the display of the information processing device.

On the other hand, the latter type is equipped with the above-mentioned pressure-sensitive sensor, electrostatic sensor, etc., so that the display as a display device becomes thicker and heavier and larger, and is expensive. It will be something like. In addition, a pressure-sensitive sensor or electrostatic sensor may malfunction if it is touched by the hand or cuffs, so touch the side of the palm with the little finger as you would when writing on a normal notebook. It is unsuitable for writing in a way that would end up.

Therefore, in order to solve such a problem,
It is possible to display the handwritten content on the display, and it is possible to easily display the handwritten content on the display and the display which is compact and can be manufactured at low cost. Provide a transparent sheet.

[0008]

That is, the present invention is a display provided in an information processing apparatus, in which input means for inputting handwriting on the front surface of the display, and input indicating contents handwritten by the input means. Input trajectory reading means for reading the trajectory, input trajectory converting means for converting the input trajectory corresponding to the handwritten content read by the input trajectory reading means into electronic data, and input trajectory data converted into electronic data by the input trajectory converting means Position information for indicating or suggesting the position of the input trajectory, which is read by the entry trajectory reading means of the writing type input device having an input trajectory data transmitting means for transmitting the information to the information processing apparatus. Is printed on the front surface thereof.

Here, the information processing device includes not only the main body of the information processing device but also a display, etc.
A general-purpose personal computer (hereinafter abbreviated as a personal computer), various mobile terminals such as mobile terminals and PDA terminals, and the like may be used as long as they have an information processing function.

As a writing type input device, for example,
As the input means, there is a pen tip that can be handwritten, and from the viewpoint of writing on the display, a pen tip that does not include ink or graphite for actually writing on a sheet may be used. And, as the input trajectory reading means provided in this writing type input device,
For example, one having a scan function or an image pickup function can be cited.

In such a case, the front surface of the display is provided with the writing type input device only by adding a simple manufacturing process of printing a mark capable of providing position information to the writing type input device. Write by the writing type input device as a writing target surface for handwriting input on the device,
The handwritten content on the front surface of the display can be converted into electronic data, and the input trajectory data corresponding to the handwritten content can be displayed on the display. Furthermore, by writing on the front surface of the display functioning as a display device, predetermined data is displayed on the display and handwritten, and further, the handwritten content is converted into electronic data. It also enables interaction.

Further, the contents of handwritten contents by the writing type input device are converted into electronic data by using the display of the information processing device, and the handwritten contents converted into the electronic data are displayed on the display. A transparent sheet placed on the front of the display,
Input means for inputting handwriting on the transparent sheet, input trajectory reading means for reading an input trajectory showing the content handwritten by the input means, and input trajectory showing the handwritten content read by the input trajectory reading means are converted into electronic data. Reading the input locus of the writing type input device, which includes input locus conversion means for performing the above, and input locus data transmission means for transmitting the input locus data converted into electronic data by the input locus conversion means to at least the information processing device. Examples include a transparent sheet printed with a mark which is read by the means and provides position information for indicating or suggesting the position of the input trajectory.

The transparent sheet may be a translucent sheet or a colored sheet as long as it has a light-transmitting property.

In such a case, if the transparent sheet is attached to the display and the front surface of the transparent sheet is used as a writing surface and handwriting is performed by the writing type input device, the handwriting can be performed. Convert the contents into electronic data,
It will be possible to display on the display. In addition, the handwriting is performed by tracing the front surface of the transparent sheet according to the predetermined data displayed on the display that can be seen through the transparent sheet, and the handwritten content is converted into electronic data. It also enables easy communication.

As described above, if the mark capable of providing position information is printed on the transparent sheet which is separate from the information processing apparatus mounted on the display, the mark can be mounted on the existing information processing apparatus as it is. In addition to being able to do so, it is possible to further simplify the production compared to printing on a display, and it is possible to expect cost reduction. In addition, even if the position information provision function is reduced due to the printed marks that can provide position information becoming thin or scratched, it is only necessary to replace the transparent sheet. It is easy for the user to handle.

Further, if it is attached to a liquid crystal display, it can be used as a liquid crystal protective sheet. Further, it becomes possible to manufacture a resin or the like capable of absorbing at least visible light as a material and apply it to an OA filter capable of reducing the external light reflectance of the display.

In order to further improve the usability of such a transparent sheet, it is desirable that the transparent sheet is detachably attached to the front or front of the display. That is, with such a structure, it can be mounted not only on one display but also on another display. Further, in order to enable the transparent sheet to be mounted on the information processing apparatus side without performing the mounting process, the transparent sheet has a mounting means for mounting it on the display. Is desirable. The mounting means may be provided integrally with the transparent sheet or may be provided separately.

As such mounting means, for example, a buckle-shaped member may be hooked on a corner portion of the display, a member may be sandwiched between the end portions of the display, or the like. As an aspect, when it is attached to the front surface of the display, an adhesive sticker that is provided on the contact surface side that comes into contact with the display and has adhesiveness or adhesiveness for sticking to the display can be mentioned. In addition, the sticking tool includes an adhesive or an adhesive that is integrally attached to a transparent sheet and an adhesive or an adhesive that is directly applied to the contact surface.

In order to improve the convenience of manufacturing,
It is desirable that the transparent sheet be detachable. Specific examples include those that can be cut off with a cutting tool such as scissors or a dedicated cutting tool, and those that can be cut off by inserting perforations and the like. In other words, if it is such a thing, the user can cut it according to the size of the display owned by each user, so the manufacturer sets several predetermined sizes. It will be sufficient to manufacture the formed sheet. Furthermore, perforations may be added to the standard size of a general-purpose display. Further, in the case of such a device, when applied to an information processing apparatus having a plurality of displays, one sheet on which a pattern providing position information is printed is cut off and position information is provided to each display. By mounting a portion having a continuous pattern, it becomes possible to give continuity to the position information of the input loci on a plurality of displays when inputting by handwriting. That is, if a plurality of displays is a dot pattern directly printed on the front surface, the dot pattern may not be continuous to each display, so the content handwritten across the plurality of displays is While it is difficult to set the information processing apparatus to recognize as an image corresponding to each display, it becomes possible to recognize the position information relatively easily.

On the other hand, as the mark providing position information printed on the display according to the first aspect of the invention and the transparent sheet according to the second aspect to the sixth aspect, information indicating the position on the writing surface is indicated or suggested. As long as the dot shapes are set, a combination of dots of these plural shapes arranged within a predetermined range is patterned, and the thickness of ruled lines arranged vertically and horizontally is changed. The pattern may be a combination of the sizes of the overlapping portions of the ruled lines within a predetermined range, but a simple and preferable one is a myriad of minute dots arranged according to a certain law. There is a dot pattern indicating planar absolute position information on the display depending on the arrangement pattern within the predetermined range. It should be noted that, as a certain law, for example, by setting reference points arranged at equal intervals in the vertical and horizontal directions and arranging dots by displacing left and right and up and down with respect to this reference point, the relative position of these dots from the reference point It is possible to use such a positional relationship.

In order to prevent the display from being hard to see due to the mark capable of providing position information,
A mark capable of providing positional information printed on the display and the transparent sheet can be read by the input locus reading unit by being transparent and being irradiated with light of a predetermined wavelength by the irradiation unit constituting the input locus reading unit. It is desirable to print with an ink that emits various light. In particular, when the mark capable of providing position information is like the dot pattern, there is a possibility that interference with the matrix-shaped pixels existing inside the display may cause a moiré fringe. By thus printing with the transparent ink, it is possible to prevent the occurrence of moire fringes.

[0022]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

The transparent sheet 1 of this embodiment is mounted on the front surface of a display 3 of a notebook personal computer (hereinafter abbreviated as personal computer) P which is an information processing apparatus shown in FIGS. Then, in the present embodiment, the handwritten content is drawn by handwriting on the front surface 1a of the transparent sheet by the electronic pen 4 which is a writable input device capable of handwriting with the front surface 1a of the transparent sheet 1 as the writing surface. Is displayed on the display 3 equipped with the transparent sheet 1.

The transparent sheet 1 can provide position information for indicating or suggesting the position of the input locus to the input locus reading means 42, which will be described later, on the front surface 1a of the translucent resin sheet. The dot pattern DP as a mark is printed. Further, in the present embodiment, as a mounting means for mounting on the display 3, an adhesive surface 11 coated with, for example, an acrylic resin adhesive is provided on the contact surface side in contact with the display 3. That is, the adhesive surface 11 functions as the sticking tool of claim 5. Then, as the adhesive, a removable one is adopted so that it can be attached to and detached from the display 3. The transparent sheet 1 is made of a resin that can be easily separated by a cutting tool such as scissors, and is mounted by separating a sheet having a size larger than that of the display 3 into a corresponding size. is there. In addition,
It is also possible to cut the transparent sheet 1 into smaller pieces and apply it to other PDA terminals, for example.

As shown in a partially enlarged view of FIG. 3, this dot pattern DP is composed of innumerable minute circular dots d arranged according to a certain law.
By the arrangement pattern within a predetermined range (for example, 2 mm square), it is possible to determine the planar absolute position on the front surface 1a of the transparent sheet that is the surface to be written. For example, intersections of ruled lines that run at equal intervals in the vertical and horizontal directions are set as reference points, and patterns are formed by using the relative positional relationship of the dots d from the reference points. In the present embodiment,
The dot pattern DP is an ink that is transparent and is irradiated with light of a predetermined wavelength by the infrared irradiation unit L that is an irradiation unit that constitutes the input trajectory reading unit 42 and emits light that can be read by the input trajectory reading unit 42. It is printed with luminescent ink. Specifically, the infrared irradiator L is provided in the CMOS camera 4b provided in the electronic pen 4, and the luminescent ink is an infrared ray having a predetermined wavelength (hereinafter referred to as excitation light) by the infrared irradiator L. Is emitted to emit infrared rays having a wavelength different from that of the excitation light and capable of being received by a CMOS sensor (not shown) of the CMOS camera 4b.

As shown in FIG. 4, the electronic pen 4 includes a pen tip 4a that does not include ink or graphite, a CMOS camera 4b that includes an infrared irradiation unit L that is an irradiation unit, a processor 4c, a memory 4d, and Bluetooth technology. A communication interface 4e such as a used wireless transceiver, a battery 4f, and the like are incorporated. The infrared irradiator L is capable of irradiating excitation light for causing the luminescent ink to emit light,
An infrared LED that emits infrared light having a wavelength that functions as this excitation light is provided. Further, the CMOS camera 4b is provided with a CMOS sensor (not shown) capable of receiving infrared rays having a wavelength different from that of the excitation light by the luminescent ink irradiated with the excitation light. Further, in the case where a filter for cutting the reflected excitation light is further provided, as shown in FIG. 6, the excitation light (indicated by reference numeral IR1 in the drawing) is applied to the dot portion (the portion where the luminescent ink exists). (A)
Emits infrared light having a wavelength different from that of the excitation light (indicated by reference numeral IR2 in the figure), but when it is irradiated to a portion without dots (a portion where the luminescent ink is not printed) (b)
In order to make use of the fact that light emission does not occur, a CMOS sensor (more specifically, CMO
A signal corresponding to an image picked up by receiving light by a photodiode constituting the S sensor) is recorded. Further, in the present embodiment, when an LED capable of irradiating infrared rays of a wavelength used when the dot pattern of carbon ink is picked up by the CMOS camera 4b is also provided, and infrared rays of either one of the wavelengths are radiated If it is not recognized by the CMOS camera 4b, the wavelength is automatically changed to the other wavelength. The infrared irradiation unit L may be a unit that can irradiate only the excitation light.

On the other hand, the electronic pen 4 will be described in terms of functions. As shown in FIG. 5, the input unit 41, the input locus reading unit 42, the input locus converting unit 43, And input locus data transmission means 44
And so on.

First, the input means 41 generates a handwritten trajectory by moving the pen tip 4a in contact with the front surface 1a of the transparent sheet 1.

The input locus reading means 42 is the input means 4 described above.
The input locus indicating the handwritten content by 1, that is, the shape of the handwritten character, symbol, or picture is read. Specifically, when the pen pressure sensor detects a pen pressure of a certain value or more of the pen tip 4a, the CMOS camera 4b operates and the infrared irradiation unit L provided in the CMOS camera 4b irradiates infrared rays having a predetermined wavelength. And the pen tip 4a
The dot pattern DP in the predetermined range in the vicinity of the pen tip 4a is successively imaged, for example, several tens to 100 times per second in accordance with the movement of the.

The input locus conversion means 43 converts the input locus read by the input locus reading means 42 into digital data by digitizing it by the processor 4c and further digitizing it. The input locus data may be stored in the internal memory 4e at least temporarily.

Further, the input locus data transmitting means 44 is
The input trajectory data is transmitted to the personal computer 2 using the communication interface 4e. It should be noted that this input locus data is further used for other information processing devices, mobile phones, PDs.
It may be configured to be able to transmit to the A terminal or the like.

This personal computer 2 is a general-purpose computer having a display 3 integrally formed in the information processing apparatus main body, and in addition to the display 3, a CP is provided on the information processing apparatus main body side.
U, internal memory, external storage device such as HDD, modem,
It has a communication interface including a communication unit for wireless communication such as Bluetooth, an input device such as a keyboard and a touch pad, etc. (these are not shown). Then, this personal computer 2 is a computer according to the program stored in the internal memory, HDD or the like in this embodiment.
By driving the PU, at least an input trajectory data receiving means 21 for receiving the input trajectory data transmitted by the input trajectory data transmitting means and an image corresponding to the input trajectory data received by the input trajectory data receiving means are displayed. It functions as the display means 22 for transmitting a display control signal to cause the display to display an image.

Next, the transparent sheet 1 of this embodiment described above.
A case will be described in which is attached to the front surface of the display 3 and the handwriting input is performed on the front surface 1a of the transparent sheet 1 with the electronic pen 4.

First, the transparent sheet 1 is cut into a size corresponding to the display 3 of the personal computer 2. Then, the transparent sheet 1 is provided on the front surface of the display 3.
The adhesive surface 11 provided on the contact surface side of the display 3 is attached and attached. Next, when the dot pattern DP of the transparent sheet 1 which can provide the positional information is read by the electronic pen 4 and transmitted, the computer 2 is properly operated.
As will be recognized by the above, for example, the personal computer 2 is set so that the position of the corner of the display 3 and the position of the corner of the transparent sheet 1 can correspond to each other. When a plurality of displays 3 are connected to the main body of the information processing apparatus and one image is divided and displayed on the plurality of displays 3, the transparent sheet 1 of the present embodiment is cut off,
The continuous portions are attached to the respective displays 3, and the information processing apparatus main body is set to recognize the position information.

Then, the pen tip 4a of the electronic pen 4 is brought into contact with the front surface 1a of the transparent sheet 1 so as to draw the trace. At this time, the electronic pen 4 operates as shown in the flowchart of FIG. When the pen pressure applied to the pen tip 4a in the electronic pen 4 is detected (step S11), the CMOS camera 4e operates to irradiate infrared rays of a predetermined wavelength in a predetermined range near the pen tip 4a by the infrared irradiation unit, The pattern DP is imaged (step S12). Imaging of the dot pattern DP is performed several tens to 100 times per second as described above. The processor 4c analyzes the picked-up dot pattern DP so that the pen tip 4 at the time of handwriting
The input trajectory associated with the movement of a is digitized and converted into data (step S13) to generate input trajectory data (step S1).
4) Then, the input trajectory data is transmitted to the personal computer 2 (step S15).

Then, the personal computer 2 receives the input trajectory data as shown in the flowchart of FIG. 8 (S2
1) Generate a display control signal for displaying an image corresponding to the input trajectory data (S22), and display an image corresponding to the input trajectory data on the display 9 (S2).
3) Will be different. At this time, the handwritten content written on the transparent sheet 1 in a state where the data created by the predetermined application is displayed on the display 3 may be combined with the data displayed on the image. Here, it is preferable that the process from the handwritten drawing using the electronic pen 4 to the image display on the display 3 be performed as soon as possible even if there is a slight time lag. This is because, in the present embodiment, the handwritten drawing using the electronic pen 4 is not physically written on the transparent sheet 1, but the dot pattern DP is read by the CMOS camera 4b by tracing the front surface 1a thereof. This is because if the handwritten content is not immediately reflected as an image display, it is difficult for the user to intuitively understand the handwritten content, and the thought is interrupted.

The transparent sheet 1 of this embodiment described in detail above.
Is mounted on the front surface of the display 3 provided in the personal computer 2, and has a dot pattern DP printed on the electronic pen 4, which can provide positional information for indicating the position of the input trajectory. Therefore, the front surface 1a of the transparent sheet 1 is used as the writing surface of the electronic pen 4 to show the content handwritten by the electronic pen 4, and the data created by the predetermined application on the personal computer 2 is displayed on the display 3. In the above, the content corresponding to the data is handwritten by tracing the front surface of the transparent sheet 1 overlaid on the image, the handwritten content is converted into electronic data, and further synthesized, such as by handwriting with the personal computer 2. You can interact. The input locus can be converted into electronic data and displayed on the display 3. Then, the display 3 can be handwritten as described above, and the handwritten content is converted into electronic data, as compared with a conventional pressure-sensitive sensor or an electrostatic sensor.
It does not complicate the configuration or increase the device size.

Further, in this embodiment, since the dot pattern DP capable of providing the position information to the input locus reading means 41 of the input pen 4 is printed on the separate transparent sheet 1 mounted on the display 3, it is used. The person side can attach it as it is to the display 3 provided in the information processing apparatus such as a personal computer, which has been used conventionally, so that it can be handwritten. The dot pattern DP can be manufactured more easily than the printing on the display 3, and the cost can be reduced. Further, even when the position information providing function is reduced due to the printed dot pattern DP becoming thin or the sheet being scratched, the transparent sheet 1 only needs to be replaced. It will be easy.

Further, when a plurality of displays 3 are connected to the main body of the information processing apparatus and used, if the displays 3 are those in which the dot patterns DP are directly printed on the front surface thereof, the dot patterns DP are respectively displayed. Since there is a possibility that they are not continuous, it is necessary to perform extremely complicated work in order for the personal computer 2 side to recognize the content handwritten over a plurality of displays 3 as an image corresponding to each display 3. However, by using a continuous part of the separate transparent sheet 1, that is, a part where the dot patterns DP are continuous, it is possible to give continuity to the positional information of the plurality of displays 3, that is, each display 3 The input locus data corresponding to can be relatively easily recognized on the personal computer 2 side and the handwritten content can be divided and displayed.

Since the transparent sheet 1 of this embodiment is made of a resin capable of absorbing visible light, it can be used as an OA filter capable of reducing the external light reflectance of the display 3. . The transparent sheet may be made of a material capable of absorbing ultraviolet rays and electromagnetic waves.

Further, as a mounting means for mounting on the display 3, on the contact surface side which contacts the display 3,
Since the adhesive surface 11 is provided for sticking to the display 3, it can be mounted very easily. Further, since the adhesive surface 11 is attachable and detachable, it can be easily attached to another display after being detached from the display 3 once.

Since the transparent sheet 1 is a resin sheet which can be easily separated with a cutting tool such as scissors, the user cuts the sheet into a size corresponding to a display provided in an existing information processing apparatus for use. Further, it can be cut into a size corresponding to another display and used.

Dot pattern DP capable of providing position information
Is printed with an ink that is transparent and is irradiated with light of a predetermined wavelength by the infrared irradiation unit L of the CMOS camera 4b provided in the electronic pen 4 and emits readable light to the CMOS camera 4b. There is a possibility that moiré fringes may occur due to interference with the matrix-shaped pixels existing inside the display. However, printing with transparent ink in this way prevents the moiré fringes from occurring and the display 3 You can prevent it from becoming hard to see.

The present invention is not limited to this embodiment.

For example, the transparent sheet 1 may be perforated in advance according to the standard size of a general display so that the user can easily cut it.

In this embodiment, the transparent sheet 1 is made of a resin capable of absorbing visible light and functions as an OA filter, but it does not have such a function. May be. When it is attached to a liquid crystal display, it may function as a liquid crystal protective sheet.

Further, in the present embodiment, as the mark capable of providing the positional information to the electronic pen 4, the dot pattern DP including the innumerable circular dots d is used. However, in addition, a plurality of dot shapes are set. However, the combination of the dots of these plural shapes arranged in the predetermined range is patterned, and the thickness of the ruled lines arranged vertically and horizontally is changed, and the size of the overlapping portion of the ruled lines in the predetermined range is changed. It may be a combination of patterns.

Alternatively, the transparent sheet 1 may be provided with a rigid frame portion. Further, as a mounting means, a buckle-like member which is hooked on the corner of the frame to the corner of the display, or the display 3
You may provide the thing which sandwiches the edge part of.

The input locus data generated by the electronic pen 4 is connected to a plurality of information processing devices via the network NET such as the Internet, either directly from the electronic pen 4 or from the personal computer 2 once transmitted, and the input locus data is input. The data may be collectively stored and may be transmitted to a server device that transmits the corresponding file data to the information processing device that is the transmission destination based on the transmission command.

Further, in the present embodiment, the dot pattern DP is printed on the transparent sheet 1 which is a separate body mounted on the front surface of the display 3 of the personal computer 2.
This dot pattern DP is displayed on a personal computer,
It may be one printed directly on the front surface of a display provided in an information processing device such as a mobile phone or PDA. Even in this case, in order to prevent the display 3 from being hard to see due to the occurrence of moire fringes, the ink for printing the dot pattern is irradiated onto the infrared irradiation unit L as described above and then the electronic pen. It is desirable to print with a luminescent ink that emits light that can be received by the CMOS camera 4b provided in the fourth embodiment.

In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
