Description

  The present invention relates to an information processing apparatus having coordinate recognition means.

  2. Description of the Related Art Conventionally, a game machine installed in a game center or the like that places a card on a stage surface and advances a game according to the attribute of the card is known (Patent Document 1: Japanese Patent Laid-Open No. 2005-46649).

According to this Patent Document 1, the stage surface has a structure that transmits invisible light, and a specially shaped code printed with invisible ink on the back surface of the card is used for an image sensor or the like disposed under the stage. The game is progressed by reading with the imaging means.
JP 2005-46649 A

  However, since the game machine is a simple system that only reads the code on the back side of the card, the game itself cannot be provided with entertainment, and the printing on the front side of the card is merely a character. It was used only with the design.

  The present invention has been made in view of the above points. When used as a game device, the present invention further enhances the entertainment characteristics of the game by devising the stage surface, while using the system as an input interface. Provides an input control instruction system having a flexible interface that can operate not only on the code on the back side of the card but also on the print area of buttons and icons printed on the card front side.

  In order to solve the above-mentioned problem, claim 1 of the present invention provides a card on which a medium ID is given and a graphic (photograph), a symbol, a character, or the like is printed on the surface instructing a touch operation with a fingertip, It comprises a fixing means for fixing the card at a predetermined position on the panel surface, an ID recognition means for the medium ID, and a panel housing provided with a coordinate recognition means for recognizing the position where the touch operation on the card is performed. Information processing apparatus.

  According to this, since the card is fixed on the panel, the coordinate system on the panel and the coordinate system on the card surface coincide with each other, and means for recognizing the position of the card itself is provided in the touch panel housing. This eliminates the need for a thinner and smaller panel housing.

  According to a second aspect of the present invention, the medium ID is a printed code or a magnetic stripe provided near a side portion of the card surface, and the card is inserted into the panel housing for sliding the card into and out of the panel surface. The information processing apparatus according to claim 1, wherein a mouth is provided, and a code reading unit that reads the code when the card is slid inserted or ejected near the insertion port is provided as an ID recognition unit.

  A third aspect of the present invention is the information processing apparatus according to the first aspect, wherein the medium ID is an RF-ID element built in a card.

  According to this, since the card is fixed on the panel, the coordinate system on the panel and the coordinate system on the card surface coincide with each other, so that means for recognizing the position of the card itself is provided in the panel housing. This eliminates the need for a thinner and smaller panel housing.

  Further, since the printed code is read when the card is introduced or ejected, if the same code pattern is repeatedly printed on the side of the card, the same code can be read a plurality of times, thereby preventing reading errors. .

  According to a fourth aspect of the present invention, there is provided a card on which a medium ID is assigned and a graphic (photograph), symbol, or character printed on the surface for instructing a touch operation with a fingertip or the like, and a panel surface on which the card is placed And an ID recognition unit for the medium ID and a panel housing provided with a coordinate recognition unit for recognizing the position where the touch operation on the card is performed.

  A fifth aspect of the present invention is the information processing apparatus according to the fourth aspect, wherein the coordinate recognition means recognizes at least the center position of the card and the orientation of the card.

  According to this, since the position on the panel is recognized by the control means of the personal computer connected to the inside or outside of the housing, any part on the card is determined from this position information and information on the touch position such as a fingertip from the panel. Can be recognized, and an operation corresponding to the figure (photograph), symbol or character on the surface of the touched card can be performed.

  According to the present invention, when used as a game device, the entertainment aspect of the game is further improved by devising the stage surface, whereas when the system is used as an input interface for a general-purpose computer or the like, only the code on the back of the card is used. In addition, it is possible to provide an input control instruction system having a flexible interface capable of operating even a button or icon print area printed on the card surface side.

  FIG. 1 shows a general-purpose computer system connected with a touch panel housing, which is a feature of the present invention.

This system includes a computer main body, a display device, and a touch panel housing. The upper surface of the touch panel housing of the present embodiment is configured as a touch panel. The details are as described in FIG. That is, a light emitting element group and a light receiving element group are arranged in pairs on each side wall of the touch panel, and light from the light emitting element is received by a medium such as a fingertip, a touch pen, or a figure. The element can no longer receive the light to be received, and it is possible to input coordinates by recognizing that these light blocking objects exist at the position. An imaging port is opened at the center of the upper surface of the touch panel, and a dot pattern printed on the back surface of the card arranged on the upper surface of the imaging port can be imaged by a camera provided in the housing.

  The touch panel may have another structure such as using an infrared imaging device as shown in FIGS.

  IRLEDs as illumination means are arranged around the camera in the touch panel housing so as to irradiate the imaging port. That is, a dot pattern on the back side of the card can be photographed by imaging the reflected light on the back side of the card in which the infrared light emitted from the IRLED is arranged at the imaging port.

  Although the dot pattern on the back of the card will be described later, the dot pattern is printed with ink that absorbs infrared rays. Therefore, even if the normal printing and the dot pattern are overprinted, it affects the shooting of the dot pattern by the camera. Not.

  FIG. 2 shows a modification of the touch panel housing. The structure of the touch panel is the same as that described with reference to FIGS. 12, 48, and 49 described above, except that a sheet with operation buttons printed on the touch panel surface and a part of the touch panel. The difference is that a display is provided.

  FIG. 3 is a hardware block diagram of the present embodiment.

  As shown in the figure, the camera includes a sensor unit, a lens and a lens holder, and an IR filter provided at the tip of the lens.

  The imaging port of the sensor unit may be processed by a central processing unit (MPU) and a frame buffer provided in the camera, or may be processed by software by a central processing unit (CPU) of the computer main body. Good.

  The central processing unit of the camera or the central processing unit of the computer main body analyzes the dot from the captured image of the dot pattern, and reads the corresponding information from the memory by converting the dot pattern into a code meaning the display, Output from the speaker.

  FIG. 4 to FIG. 11 explain such a dot pattern.

  4 to 5 are explanatory diagrams showing the relationship among the dot pattern, the code value, and the identifier.

As shown in FIG. 4, the dot pattern is a dot pattern composed of 4 × 4 block areas, and is partitioned into C _{1-0 to} C _31-30 in this block. FIG. 5 shows the dot code format of each area.

As shown in FIG. 5, C ₀ ~C ₂₃ which means each of the data area and a company code, C ₂₄ -C ₂₅ code distinction, C ₂₆ -C ₂₉ are managed code, C ₃₀ -C ₃₁ are parity. There are four types of formats, the value of C ₂₄ -C _25, the number of bits of the data area and the company code are determined. That is, 8-bit and company code is 16-bit data area in the case of C ₂₄ -C ₂₅ is 00, the 12-bit data area 12 bits and the company code in the case of 01, the data area in the case of 10 When 16 bits and the company code are 8 bits and 11, the data area is 20 bits and the company code is 4 bits.

  Next, a dot pattern used in the present invention will be described with reference to FIGS.

  FIG. 6 is an explanatory diagram showing GRID1, which is an example of the dot pattern of the present invention.

  In these drawings, vertical and horizontal grid lines are provided for convenience of explanation, and are not present on the actual print surface. The key dots 2, information dots 3, reference grid point dots 4 and the like constituting the dot pattern 1 are made of invisible ink or carbon ink that absorbs infrared light when the scanner as imaging means has infrared irradiation means. It is desirable that it is printed.

  FIG. 7 is an enlarged view showing an example of dot display information dots and bit display of data defined in the dot. FIGS. 8A and 8B are explanatory diagrams showing information dots arranged around key dots.

  The information input / output method using a dot pattern according to the present invention includes generation of a dot pattern 1, recognition of the dot pattern 1, and means for outputting information and a program from the dot pattern 1. That is, the dot pattern 1 is captured as image data by the camera, the reference grid point dot 4 is extracted first, and then the key dot 2 is extracted because the dot is not originally placed at the position where the reference grid point dot 4 is located. Next, the information dot 3 is extracted and digitized to extract an information area to digitize the information, and information and a program are output from the dot pattern 1 based on the numerical information. For example, information or a program such as voice is output from the dot pattern 1 to an information processing apparatus, personal computer, PDA, mobile phone or the like.

  The dot pattern 1 according to the present invention is generated in accordance with a predetermined rule for fine dots, that is, key dots 2, information dots 3, and reference lattice point dots 4, in order to recognize information such as voice by a dot code generation algorithm. Arrange. As shown in FIG. 6, in the block of dot pattern 1 representing information, a 5 × 5 reference grid point dot 4 is arranged based on the key dot 2 and the center of the block surrounded by the four reference grid point dots 4 is arranged. Information dots 3 are arranged around the virtual grid point 5. Arbitrary numerical information is defined in this block. In the illustrated example of FIG. 6, a state is shown in which four blocks (inside the bold line frame) of the dot pattern 1 are arranged in parallel. Of course, the dot pattern 1 is not limited to four blocks.

  One corresponding information and program can be output to one block, or one corresponding information and program can be output to a plurality of blocks.

When the dot pattern 1 is captured by the camera as the image data, the reference grid point dot 4 corrects distortion of the lens of the camera, imaging from an oblique direction, expansion / contraction of the paper surface, curvature of the medium surface, and distortion during printing. Can do. Specifically, a correction function (X _n , Y _n ) = f (X _n ′, Y _n ′) for converting the distorted four reference grid point dots 4 into the original square is obtained, and the same function is obtained. Then, the information dot 3 is corrected to obtain a correct information dot 3 vector.

  If the reference grid dot 4 is arranged in the dot pattern 1, the image data obtained by capturing the dot pattern 1 with the camera corrects the distortion caused by the camera. Even when the image data of the dot pattern 1 is captured by the camera, it can be accurately recognized. Even if the camera is tilted and read with respect to the surface of the dot pattern 1, the dot pattern 1 can be accurately recognized.

  As shown in FIG. 6, the key dot 2 is a dot in which four reference grid point dots 4 at the corners of the four corners of the block are shifted in a certain direction. The key dot 2 is a representative point of the dot pattern 1 for one block representing the information dot 3. For example, the reference grid point dots 4 at the corners of the four corners of the block of the dot pattern 1 are shifted upward by 0.1 mm. When the information dot 3 represents the X and Y coordinate values, the coordinate point is a position where the key dot 2 is shifted downward by 0.1 mm. However, this numerical value is not limited to this, and can be changed according to the size of the block of the dot pattern 1.

  The information dot 3 is a dot for recognizing various information. The information dot 3 is arranged around the key dot 2 as a representative point, and the center surrounded by the four reference grid point dots 4 is set as a virtual grid point 5 and expressed as a vector using this as a starting point. Arranged at the end point. For example, the information dot 3 is surrounded by the reference grid point dot 4, and as shown in FIG. 7A, a dot 0.1 mm away from the virtual grid point 5 has a direction and length expressed by a vector. Therefore, it is rotated 45 degrees clockwise and arranged in 8 directions to represent 3 bits. Accordingly, 3 bits × 16 pieces = 48 bits can be expressed by one block of dot pattern 1.

FIG. 7B is a method of defining information dots 3 having 2 bits for each grid in the dot pattern of FIG. 6, and each 2-bit information is shifted by shifting the dots in the + direction and the x direction. Defined. Thus, although 48-bit information can be originally defined, data can be given every 32 bits by dividing according to usage. A maximum of 2 ¹⁶ (about 65000) dot pattern formats can be realized by combining the + direction and the X direction.

  Note that the present invention is not limited to this, and it is possible to represent 4 bits by arranging in 16 directions, and it is needless to say that various changes can be made.

  The diameter of the key dot 2, the information dot 3 or the reference grid point dot 4 is preferably about 0.05 mm in consideration of appearance, printing accuracy with respect to paper quality, camera resolution, and optimal digitization.

  Further, in consideration of a necessary amount of information with respect to the imaging area and misidentification of the various dots 2, 3, and 4, it is desirable that the interval between the reference grid point dots 4 is about 0.5 mm vertically and horizontally. In consideration of misrecognition of the reference grid point dot 4 and the information dot 3, the shift of the key dot 2 is preferably about 20% of the grid interval.

  The distance between the information dot 3 and the virtual grid point surrounded by the four reference grid point dots 4 is preferably about 15 to 30% of the distance between the adjacent virtual grid points 5. This is because if the distance between the information dot 3 and the virtual lattice point 5 is closer than this distance, the dots are easily recognized as a large lump and become unsightly as the dot pattern 1. On the contrary, if the distance between the information dot 3 and the virtual grid point 5 is longer than this distance, it is difficult to identify which of the adjacent virtual grid points 5 is the information dot 3 having the vector directivity. Because it becomes.

For example, in the information dot 3, as shown in FIG. 8A, the lattice interval in which I ₁ to I ₁₆ are arranged clockwise from the block center is 0.5 mm, and 3 bits × 16 = 48 in 2 mm × 2 mm. Represents a bit.

In addition, it is possible to further provide sub-blocks having independent information contents in the block and not affected by other information contents. FIG. 8B illustrates this, and sub-blocks [I ₁ , I ₂ , I ₃ , I ₄ ], [I ₅ , I ₆ , I ₇ , I, which are constituted by four information dots 3. ₈ ], [I ₉ , I ₁₀ , I ₁₁ , I ₁₂ ], [I ₁₃ , I ₁₄ , I ₁₅ , I ₁₆ ] are independent data (3 bits × 4 = 12 bits) developed into information dot 3 It has come to be. By providing sub-blocks in this way, error checking can be easily performed on a sub-block basis.

  It is desirable that the vector direction (rotation direction) of the information dots 3 is uniformly determined every 30 to 90 degrees.

  FIG. 9 shows an example of the information dot 3 and the bit display of the data defined therein, and shows another form.

  In addition, using two types of information dots 3 that are long and short from the virtual lattice point 5 surrounded by the reference lattice point dot 4 and eight vector directions, 4 bits can be expressed. At this time, it is desirable that the longer one is about 25 to 30% of the distance between adjacent virtual lattice points 5, and the shorter one is about 15 to 20%. However, it is desirable that the center interval between the long and short information dots 3 is longer than the diameter of these dots.

The information dot 3 surrounded by the four reference lattice point dots 4 is preferably one dot in consideration of appearance. However, if it is desired to ignore the appearance and increase the amount of information, one bit is assigned to each vector, and the information dot 3 is expressed by a plurality of dots, so that a large amount of information can be provided. For example, the vector of concentric eight directions, an information dot 3 surrounded by four points lattice dots 4 can represent information of 2 ^8, and 16 pieces of information dots of one block 2 ^128.

  FIG. 10 shows an example of information dot and bit display of data defined therein. (A) shows two dots, (b) shows four dots, and (c) shows five dots arranged. It is shown.

  FIG. 11 shows a modification of the dot pattern, where (a) is a six information dot arrangement type, (b) is a nine information dot arrangement type, (c) is a 12 information dot arrangement type, and (d). Is a schematic diagram of a 36 information dot arrangement type.

  The dot pattern 1 shown in FIGS. 6 and 8 shows an example in which 16 (4 × 4) information dots 3 are arranged in one block. However, the information dots 3 are not limited to 16 pieces arranged in one block, and can be variously changed. For example, according to the amount of information required or the resolution of the camera, six information dots 3 (2 × 3) are arranged in one block (a), and nine information dots 3 in one block (3 × 3) Arranged (b), 12 (3 × 4) information dots 3 arranged in one block (c), or 36 (d) arranged 36 information dots 3 in one block.

  A method for calculating the XY coordinate value using the above-described dot pattern will be described with reference to FIG.

  When the dot pattern 1 is captured as image data by the camera, after calculating the XY coordinate value at the position of the key dot 2 which is the representative point of information, the direction of the dot pattern 1 obtained from the key dot 2 and the adjacent representative point The XY coordinate value of the imaging center is calculated by complementing the coordinate value from the increment value of the XY coordinate value and the distance from the imaging center to the key dot 2 where the XY coordinate value is calculated.

  Or, when the block of the dot pattern 1 is captured as image data by the camera, in the area where the same data is defined in each block, or the area where the XY coordinate values are defined, it is around the imaging center of the camera Start reading from information dot 3, read information dot 3 sequentially, read information dot 3 corresponding to one block, read dot pattern 1 in the smallest area from the imaging center of the camera, and calculate the data at the imaging center position To do.

  FIG. 50A shows the order of inputting information dots corresponding to one block in the minimum area from the imaging center of the camera. 4 information × 4 columns = 16 information dots are inputted in the clockwise direction.

  FIG. 50B is an explanatory diagram showing a method for reading a dot pattern and calculating an XY coordinate value.

As shown in the figure, the XY coordinate value to be obtained is the XY coordinate value of the block having the imaging center of the camera. When the increment value of the XY coordinate value is set to +1 in the X direction (right direction) and the Y direction (upward direction) for each block, it is necessary to correct information dots input from other blocks. K ₈ K ₇ K ₆ K ₅ (i ₁₆ i ₁₅ i ₁₄ i ₁₃ i ₁₂ i ₁₁ i ₁₀ i ₉ ) indicating the X coordinate value and K ₄ K ₃ K ₂ K ₁ (i ₈ ) indicating the Y coordinate value. i ₇ i ₆ i ₅ i ₄ i ₃ i ₂ i ₁ ) are subject to correction, and other blocks K _{16 to} K ₉ (i _{32 to} i ₁₇ ) have the same value and need not be corrected.

  These calculations are obtained by the following equations (1) to (16). Even if the digit is increased by the calculation in [], it does not affect the sequence of bits before []. Let K be the information dot I minus the error check bit.

  When an error occurs in the information dot 3 when the dot pattern 1 is captured as image data by the camera, the closest information dot 3 corresponding to the information dot 3 is read, and the error is corrected, so that the image is captured from the center of the camera. The dot pattern 1 can be read in the minimum area.

  A tablet, digitizer, and input interface using XY coordinates can be realized by using the information capturing method described above. For example, a tablet or digitizer superimposes a transparent sheet on which a dot pattern 2 is printed on an object, takes an image of the camera, and inputs the XY coordinate values of the dot pattern 1.

  51 and 52 are diagrams showing specific examples of dot patterns in which XY coordinates are defined.

As shown in FIG. 51A, four dot patterns (1) to (4) are formed. The dot code format in each dot pattern is as shown in (b). That is, C _{0 to} C ₇ are Y coordinates, C _{8 to} C ₁₅ are X coordinates, C _{16 to} C ₂₀ are operation codes, C _{21 to} C ₂₉ are content / application codes, and C _{30 to} C ₃₁ are parity. is doing. The operation code and content / application code are information related to the contents of the card and operations performed by the card.

  Here, assuming that the X coordinate value of the dot pattern (1) is 10 and the Y coordinate value is 20, the X coordinate and Y coordinate values of the dot patterns (2) to (4) are expressed in (a). It becomes the value shown. Further, assuming that the operation code is 10 and the content / application code value is 100, the formats of the dot patterns (1) to (4) are as shown in (b).

  FIG. 52 is a diagram specifically representing the values shown in FIG. 51B with a dot pattern.

  FIG. 12 is a diagram illustrating a structure for recognizing coordinates on the touch panel as described above.

  FIG. 13 is a diagram illustrating a method for calculating a position touched with the fingertip of the operator / player (touch position).

In the touch panel (coordinate recognition means) coordinate system, the coordinates of the center position of the camera (imaging means) are (X _s , Y _s ).

In addition, a position where the photographing center position of a card photographed by the camera is expressed in the card coordinate system is (x _s , y _s ).

  On the other hand, an angle formed by the Y direction in the coordinate system of the touch panel and the y direction in the card coordinate system is θ.

In this case, it is assumed that the touch position at the fingertip of the operator or player is (X _t , Y _t ) when displayed in the touch panel coordinate system.

  In this case, the touch position in the card coordinate system is expressed by the following expression.

  By performing such arithmetic processing, it is possible to recognize which part printed on the card surface is touched with the fingertip, regardless of the orientation of the card on the touch panel surface. It becomes possible.

  In FIG. 13A, the case where the touch on the card surface is performed with the fingertip of the operator / player has been described, but it is needless to say that the touch may be performed with a touch pen or the like.

  FIG. 14 is an explanatory diagram showing a modification of the present embodiment.

  The touch panel housing has a plurality of imaging openings. As in the case shown in FIG. 1, cameras are arranged in the touch panel housing corresponding to each imaging port in a state in which the direction of the imaging port can be photographed corresponding to each imaging port. In (a), when a card is placed on any one of the imaging ports on the touch panel surface side, the corresponding camera captures a dot pattern on the back side of the card. Then, processing corresponding to each dot pattern unique to each imaging port, that is, the dot pattern is analyzed from the captured image, and the corresponding sound, image, and moving image are output.

  In (b), a plurality of imaging openings (here, nine) are arranged so that the back side of the card can be photographed no matter where the card is arranged on the touch panel surface. By arranging the imaging openings in this way, the dot pattern on the back side of the card can be photographed regardless of the position of the card on the touch panel surface without being conscious of the operator / player.

  As described above, according to the present embodiment, a medium such as a card placed on the stage is recognized by a dot pattern printed on the back surface, and the player's touch on the medium surface can be recognized. From the result, it is possible to calculate which part of the card arranged on the stage is touched, and to perform processing according to the characteristics of the card. That is, it is possible to give an input instruction in accordance with the characteristics of the game and the information processing apparatus only by preparing a card on which a region for performing a touch operation is printed.

  FIG. 15 is a perspective view showing an overview of a touch panel casing (card game device) according to another embodiment of the present invention.

  As shown in the figure, the touch panel housing (card game device) is provided with a display in front of the touch panel, and touches the position of the card or the fingertip of the player on the touch panel or the fingertip with respect to the card surface on the touch panel. The game progress changes by touching. Along with that, the images and moving images displayed on the display also change.

  FIG. 16 is a perspective view showing another form of the touch panel housing (game device) in the present embodiment, in which a display is provided on the right side of the stage surface.

  As described above, a part of the touch panel surface of the stage surface is configured as a display, so that it is possible to display a moving image, a score, and the like according to the progress of the game. In this figure, even if a card is placed in the display area, the dot pattern on the back of the card cannot be recognized, but the display part also has a touch panel function and is displayed on the display. It is possible for a player to directly touch and control icons and buttons.

  The internal structure of the touch panel casing is the structure shown in FIG. In this embodiment, for example, when a card on which a dot pattern is printed is placed on the touch panel (stage surface), the infrared irradiation light emitted from the IRLED irradiates the entire lower surface of the touch panel via the reflector on the frame. Is done. The infrared irradiation light reflected on the back side of the card is imaged by the camera.

  When the sensor unit and the central processing unit (MPU) read the dot pattern printed on the card, the dot pattern is converted into a code value, and an image / moving image corresponding to the code value is displayed on the display device. .

  18 to 19 illustrate a touch panel casing (card game apparatus) that is characterized in that an image is displayed on the touch panel (stage surface) in another touch panel casing (card game apparatus) of the present embodiment. Is.

  In this embodiment, along with the camera (imaging means) on the side of the touch panel lower space (stage lower space), an image or moving image projected on the stage surface by the code value of the dot pattern obtained from the image captured by the camera It is characterized in that a projector is arranged as a projection means for controlling an image.

  In this embodiment, for example, when a card on which a dot pattern is printed is placed on the touch panel (stage surface), infrared light irradiated from the IRLED is irradiated to the entire lower surface of the touch panel via a frame-shaped reflector. Is done.

  The infrared irradiation light reflected on the back side of the card is reflected by the mirror and imaged by the camera. At this time, an image or a moving image is projected from the projector onto the lower surface of the stage surface via a mirror.

  When the sensor unit and the central processing unit (MPU) read the dot pattern printed on the card, the dot pattern is converted into a code value, and an image / moving image corresponding to the code value is projected from the projector.

  As described above, the projector projects the image / moving image from the lower surface of the stage surface, and the projected image / moving image is controlled by the card on which the dot pattern placed on the stage surface is printed. .

  Even in such a system equipped with a projector, the image and moving image displayed on the stage surface can be controlled by the arrangement position of the card on the touch panel and the like, for example, playback, fast forward, rewind, etc. on the card surface. The moving image projected from below the touch panel (under the stage) may be controlled by printing the icon and touching the icon area with a fingertip (see FIG. 37).

  20 to 23 are diagrams illustrating a dot pattern used for a card used in the touch panel casing illustrated in FIGS. 15 to 19.

  The basic algorithm of this dot pattern is almost the same as that described with reference to FIGS. 4 to 11, but only one dot pattern expressing one code is printed and indicates the direction of the dot pattern. The difference is that it has direction dots.

  20 to 21 are explanatory diagrams showing the relationship among the dot pattern, the code value, and the identifier.

As shown in FIG. 20, the dot pattern is a dot pattern composed of 3 × 3 block regions, and is partitioned into C _{1-0 to} C _17-16 within this block. FIG. 21 shows the dot code format of each area.

As shown in FIG. 21, C _{0 to} C ₅ mean operation codes, C _{6 to} C ₁₅ mean content / application codes, and C _{16 to} C ₁₇ mean parity.

  FIG. 22 shows the arrangement direction of the information dots 3 only in a specific lattice area (direction area) in the dot pattern of the block composed of 3 × 3 = 9 lattice areas in the dot patterns described in FIGS. The direction of the block is defined by changing to the other lattice area (direction area).

  That is, in FIG. 22, the information dots 3 are arranged in the vertical and horizontal directions from the center in the lower left lattice region 34a, the central lattice region 34b, and the lower left lattice region 34c, and in the other lattice regions, the information dots 3 are inclined in the oblique direction from the center. Is arranged. By arranging the lattice areas 34a, 34b, and 34c in this way, it can be recognized that the block is upward from the shape of the triangle connecting the lattice areas, that is, the relationship of the vertex 34b with respect to the bases 34a and 34c.

  As described above, the direction of the block is defined by the arrangement relationship (here, a triangle) of the lattice areas 34a, 34b, and 34c in which the arrangement direction of the information dots 3 in the block is changed (information dots are arranged in the vertical and horizontal directions from the center). be able to. As a result, since the information dots 3 can be arranged in all the lattice areas in the block, the information dots 3 can be arranged in all the lattice areas without sacrificing the lattice area for the key dots. it can.

  FIG. 23 is a diagram illustrating an arrangement state of the information dots 3 corresponding to FIG.

  When the dot pattern is printed on the back side of the card, it is desirable that the distance between the lattices is about 15 mm and the dot size is about 15% of the distance between the dots. Therefore, 2 mm to 2.5 mm is desirable, but not limited thereto. The resolution of the inter-dot distance at the time of imaging is desirably 14 pixels or more.

  FIG. 24 is a diagram illustrating a method of calculating a position (touch position) touched with the fingertip of the operator / player.

The width of the card is W, the height is H, and the coordinates of the card center position in the touch panel coordinate system are (X _c , Y _c ). Further, the rotation angle of the card, that is, the angle formed between the Y direction of the touch panel coordinate system and the y direction of the card coordinate system is denoted by θ.

  In this case, it is assumed that the touch position at the fingertip of the operator / player is (Xt, Yt) when displayed in the touch panel coordinate system.

In this case, the touch position (x _t , y _t ) in the card coordinate system is expressed by the following expression.

  By performing such arithmetic processing, it is possible to recognize which part printed on the card surface is touched with the fingertip, regardless of the orientation of the card on the touch panel. It becomes.

  In FIG. 24A, the case where the touch on the card surface is performed with the fingertip of the operator / player has been described, but it is needless to say that the touch may be performed with a touch pen or the like.

  FIG. 25 is a diagram for explaining coordinate recognition means (touch panel) having a notch or a curved peripheral wall for allowing the medium on the panel or stage surface to exit from the panel surface in a part of the peripheral edge of the panel. It is.

  In FIG. 25 (a), on one surface S1 of the peripheral wall, infrared irradiation elements as transmitting parts and light receiving elements as receiving parts are alternately arranged adjacent to each other or every plurality. On the other hand, on the surfaces S2 and S3 adjacent to the one surface S1 of the peripheral wall, an infrared irradiation element or a light receiving element is arranged, respectively, and the fingertip of an operator who directly touches the panel or stage with the infrared light irradiated from the infrared irradiation element, Alternatively, the XY coordinates of the fingertip on the panel or stage can be recognized by the light receiving element on the opposite surface not receiving the irradiation light blocked by the fingertip of the player / operator who touched the medium on the panel or stage. .

  Here, since the opposing surface S4 of the one surface S1 is configured as a notch, it is easy to leave a medium such as a card from the notch with the fingertip from the panel or the stage surface.

  In the example shown in the figure, the state in which the fingertip of the operator / player touches the panel or the stage surface has been described. However, a solid object such as a touch pen or a figure may be used instead of the fingertip.

  (B) is a peripheral wall that incorporates a coordinate recognition means of the panel or stage at the peripheral edge of the panel or stage and rises in a curved shape from the panel or stage surface in order to cause the medium on the panel or stage surface to exit the panel surface ( It is a figure explaining the coordinate recognition means (touch panel) provided with curved surrounding wall part SW).

  As the coordinate recognizing means, an infrared irradiation element and a light receiving element for receiving the infrared light are provided on the peripheral edge (peripheral wall).

  In this way, the card can be taken out very easily by using a curved peripheral wall SW in which a part of the peripheral wall is curved from the touch panel surface.

  In FIG. 26, a card insertion slot is provided on the side of the touch panel housing, and a card on which a code is printed as a dot pattern on the back side from the card insertion slot and key buttons such as alphabets are printed on the front side is inserted. It is possible to do. An imaging port is provided on the touch panel surface side of the touch panel casing, and a dot pattern printed on the back side of the card inserted from the insertion slot by the imaging means (camera) can be read from within the casing.

That is, by recognizing the code read from the dot pattern on the back side of the card and the position of the XY coordinates touched by the operator, the player or the user on the touch panel surface, the control means determines which area printed on the card surface is touched. Can be recognized.

As described above, according to the touch panel housing shown in FIG. 26, since the card can be taken in and out from the card insertion slot, the card can be easily taken out from the touch panel without providing a notch.

According to FIG. 26, since the card inserted from the card insertion slot is reliably positioned on the touch panel surface, the XY coordinate system on the card surface and the XY coordinate system recognized by the touch panel are completely coincident with each other. It is easy to recognize a touch position on a fingertip or a medium on the card without performing a complicated calculation.

In addition, printed on the card surface is the same alphabetical keyboard tops as the keyboard, but it is not limited to such alphabets, for example, icons, photos, illustrations, etc. are printed with areas separated. May be.

  The information processing apparatus according to the present invention can be used for various purposes by changing the contents of the card. 27 to 46 are diagrams illustrating specific examples of cards.

  All of the cards shown below are used by being placed on the touch panel housing described above.

  When the card is placed by the operator / player, as described above, the dot pattern is read by the camera inside the touch panel housing and converted into a code value by the central processing unit of the camera or computer. Thereby, the contents of the card are recognized. Further, when the icon or picture printed on the card surface is touched by the operator / player, the touched position is recognized as described above, and processing corresponding to the icon instruction or the contents of the picture is performed.

  FIG. 46 shows a modification of the card as a medium. This card can realize the same function as a mouse as an auxiliary input device of a general-purpose computer as a mouse card.

  That is, on the surface of the mouse card, right click button and left click button icons corresponding to the mouse click buttons are printed, and further, scroll buttons in the vertical and horizontal directions for scroll control of the screen are printed as icons. Has been.

  The card is provided with a mouse pad area, and the displayed screen may be controlled by moving a fingertip in the mouse pad area.

  In addition, a dot pattern is printed on the back surface of the mouse card, and the dot pattern is patterned by a predetermined algorithm (described with reference to FIGS. 4 to 11) with code values and coordinate values.

  By mounting such a mouse card on the touch panel casing provided with the insertion slot shown in FIG. 26, the touch panel casing can function as an auxiliary input device such as a mouse or a controller.

  As described above, if the card is fixed on the touch panel surface by providing an insertion slot, the positional relationship between the touch panel and the card is determined, so only the code value can be obtained from the dot pattern on the back of the card. It will be good.

  FIG. 46B shows a mouse card similar to that described above, but is suitable for a touch panel housing having a relatively wide stage surface. By moving the mouse card itself up, down, left, and right, the stage surface The image displayed above or the image displayed on a separate display device can be controlled.

  It should be noted that the embodiments of the card and medium placed on the touch panel housing are not limited to the above, and various embodiments can be considered.

  FIG. 47 shows a standing type touch panel casing.

  This standing touch panel housing is substantially the same as the touch panel structure shown in FIGS. 12, 48, and 49, except that suction ports are provided on the matrix around the entire surface of the imaging port. Is a feature. A vacuum suction pump (not shown) is provided inside the touch panel casing, and a negative pressure space is formed in the touch panel casing. The vacuum suction pump is operated by an instruction signal from a control device (CPU). When a card provided in the vicinity of the image pickup port is detected by a camera provided inside the image pickup port, the control device (CPU) operates the vacuum suction pump so that the back surface of the card is a touch panel. Vacuum suction is started so as to be in close contact with the surface.

  As described above, by providing the vacuum suction port, the card can be securely fixed on the touch panel even in a standing type touch panel.

  FIG. 48 (a) shows another embodiment of the touch panel (coordinate recognition means).

  That is, a pair of infrared imaging devices (camera A and camera B) for causing the stage to function as coordinate recognition means are provided at both inner ends of one side constituting the peripheral wall of the panel.

  The control means analyzes the images picked up by these infrared image pickup devices so that the XY coordinates of the player / operator's fingertip, pen, or three-dimensional object on the panel or stage can be recognized.

  Also, one side of the peripheral wall has a notch, and it is easy to allow the card as a medium to be withdrawn from the stage surface or panel surface from the notch.

  Infrared irradiation elements are provided on both sides of the cameras A and B, and the camera images the reflected infrared light emitted by the infrared irradiation elements. Although not shown in the drawings, each camera A and B is provided with an IR filter so that the reflected light can be imaged.

  The inner surface of the peripheral wall is configured as a retroreflective surface, and has a characteristic of reflecting infrared rays in the same direction as the incident angle of infrared rays.

  FIG. 5B shows images captured by the camera A and the camera B. When the player's fingertip is positioned on the stage surface, the images of the portions F1 and F2 (fingertip) are the other portions. Images with different reflected light. Therefore, the XY coordinates of the fingertip on the stage surface can be calculated by analyzing the images of both cameras A and B.

  That is, the angle α can be calculated by recognizing the position of F1 from the captured image of the camera A, and the angle β can be calculated by recognizing the position of F2 from the captured image of the camera B, so that the coordinate values (X, Y) are It can be calculated.

  Note that position recognition may be performed by detecting a difference between an image when such a fingertip does not exist on the stage surface and an image touched with the fingertip.

  49 has substantially the same configuration as that of FIG. 48, except that FIG. 48 is provided with a notch in the downward direction in the drawing, but is provided on one side of the peripheral wall in the upward direction.

  Thus, even if the cutout portion exists in the imaging field of view of the cameras A and B, if the reflected image of the cutout portion is held as a reference image in advance as an initial image, the captured image when the fingertip is touched is used. Since the difference can be detected, the XY coordinates of the fingertip can be easily calculated.

  FIG. 53 shows another embodiment of the present invention. That is, in this embodiment, card ID recognition (medium ID recognition) is possible without using a dot pattern.

  As shown in the figure, the touch panel casing, which is a panel casing, has a side wall corresponding to the shape of the card, and by inserting the peripheral edge of the card into the inner surface of the side wall, It is supposed to be fixed.

  Further, the card has a semicircular cutout, and the card can be detached from the touch panel surface by inserting a fingertip into the cutout.

In addition to the case where it is provided on the card side as shown in FIG. 53 (a), the notch may be provided on the side wall portion side as shown in FIG. 53 (b).
The light-emitting elements and light-receiving elements described with reference to FIG.

  In this embodiment, since the card is always fixed at a predetermined position on the touch panel surface, the coordinate system recognized by the touch panel matches the coordinate system on the card surface, so the position of the card other than the touch panel on the touch panel housing side. There is no need for recognition.

  An RF-ID element is built in the card, and a card ID is registered in a memory in the RF-ID element.

  The touch panel casing is provided with a transmitting / receiving element capable of communicating with the RF-ID element, and the card ID of the card fixed to the touch panel casing can be recognized.

  Note that a control means (not shown) such as a central processing unit (CPU) may be provided in the touch panel casing, or a central processing unit (CPU) on the personal computer side connected to the touch panel casing. The control means may be used.

In the present embodiment, when the transmitting / receiving element of the touch panel casing recognizes the card ID, the control means starts an application registered in advance corresponding to the card ID.
Then, the control means recognizes which part (position) of the card surface has been touched with a fingertip or the like by a signal from the touch panel, and performs an operation corresponding to the position (for example, playback or stop of a moving image). .

  The touch panel may be one that optically recognizes coordinates shown in FIG. 12, or may be a pressure-sensitive type. Moreover, you may touch the predetermined position on the card | curd surface with touch pens other than a fingertip.

  In FIG. 53 (a), the card ID is described as being stored in the RF-ID element. However, any means can be used as long as the card ID can be registered, as shown in FIG. 53 (b). A QR code, a bar code, a dot pattern, and other print codes may be printed on the back side of the card. Also, other recognition means may be used.

  Further, the card ID may be given different IDs on the front and back surfaces. As a result, the front and back surfaces of the card can be recognized, and another operation can be performed using the front and back surfaces of the card.

  Note that the touch panel structure shown in FIGS. 25, 47, 48, and 49 may be used.

  A display area may be provided on the touch panel surface as shown in FIG.

  In FIG. 54, a part of the side wall of the touch panel housing is opened to provide a card insertion slot.

  A sensor unit is provided at one side of the card insertion slot, and an optical bar code reader is built in the sensor unit.

  On the other hand, the card ID is printed as a bar code near the side surface of the card surface, and the card ID is read by the bar code reader of the sensor unit when the card is slid into and out.

  The card ID may be printed by repeating the same pattern. In that case, the card ID can be read a plurality of times by one insertion operation. In this case, reading errors can be prevented.

  Although the card ID is described as a barcode printed near the side of the card surface, a magnetic stripe may be provided in this portion. In that case, the sensor part near the card insertion slot may be constituted by a magnetic head.

  Furthermore, the card ID may be registered in the RF-ID memory as described in the above embodiment (FIG. 53). In this case, the control means can recognize the card ID through communication with the transmitting / receiving element in the touch panel casing.

  Further, a touch panel similar to that described with reference to FIG. 53 is provided on the side wall portion of the touch panel casing, and coordinates can be recognized when the fingertip on the card surface is touched.

  Also in this embodiment, when the sensor unit of the touch panel casing recognizes the card ID, the control unit starts an application registered in advance corresponding to the card ID.

  Then, the control means recognizes which part (position) of the card surface has been touched with a fingertip or the like by a signal from the touch panel, and performs an operation corresponding to the position (for example, playback or stop of a moving image). .
