Abstract

<P>PROBLEM TO BE SOLVED: To provide an information input system using a right-angled triangle which is easily read by a computer and easy for a person to figure by handwriting. <P>SOLUTION: Three sides of a large right-angled triangle are each equally divided (by 9 in Fig. 1) to form similar small right-angled triangles. The six rows and six columns in the middle part of longitudinal areas 3 to 8 and lateral areas 2 to 7 of small right-angled triangles indicated by dotted lines are used as a vowel area, and the remaining two oblique-side columns and one base column are used as a consonant area. For example, three parts in the vowel area are painted out as shown in Fig. 1 to represent an English letter O and two parts in the consonant area are painted out to represent an English letter T. Consequently, the representation result is TO (a Roman letter in Japanese). On a read side, a painted-out figure of small right-angled triangles is optically read as a piece of information and input to the computer, and the figure is converted into a voice of "TO" in Japanese on the basis of figure/speech correspondence information held in the memory of the computer to voice the figure. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an image or figure that can be read by optical means such as a digital camera, and more particularly to an information input method using a triangular figure that can be expressed by a computer.

  As a general-purpose image or figure input method, there are a two-dimensional code, a one-dimensional bar code, and a carla code read using OCR. A two-dimensional code or the like is printed by a machine and read by the machine, and various proposals have been made (for example, see Patent Document 1).

  Since handwritten symbols are read by handwritten OCR and target highly redundant handwritten characters, it is necessary to define the reading environment in detail, such as setting the character frame and specifying the distance between the character face and the camera. An analysis program for normalizing image information in the frame is required.

On the other hand, an information input method using a Carla code is also known (see, for example, Patent Document 2). Although the Carla code can be handwritten, it is intended to embed information in a small area, so the redundancy of the symbol is kept low, and the symbol size, pitch, direction between the entry side and the reading side Must be adjusted in advance.

It is assumed that one large right triangle is the character area, the other large right triangle is the tone area, and is read by the computer as combined information of both areas, converted into a specific character that takes into account the tone, and expressed. Configured.

  As a result, the simple means of painting a right triangle with a shape that is easy to identify with a circle is composed of a character area and a tone area as one set, and the tone of ethnic words without letters is added. It is possible to provide a sound that adds tone to the visually impaired on the ground.

  The invention according to claim 4 of the present invention optically reads the described graphic as collective information and inputs it to a computer, and converts the graphic into sound based on graphic / speech correspondence information stored in the memory of the computer. The above described figure is composed of a large right triangle and a right triangle divided into a plurality of equal small right triangles, and one piece of information of the large right triangle. And one large right triangle is used as a character area, and the other large right triangle is used as a tone area, which is read by a computer as combined information of both areas, and converted into a specific character taking into account the tone. A specific word or meaning is expressed by characters obtained by using a plurality of pairs of triangles.

  Thus, by constructing a simple means of painting a right triangle as a pair of a character region and a tone region, a tribal word or meaning having no characters is expressed taking into account the tone, Voice guidance can be given to visually impaired people in terms of town names, station names, etc. in words or meanings. In addition, the provision of audio information to underwater workers and the transmission of information between underwater swimmers can be expressed closer to the human language, taking into account the tone.

  It is easy to identify with a circle, and by simply filling a right triangle with a shape that can specify the top, bottom, left, and right, it becomes a phonetic symbol that can be easily handwritten by a person and read by a computer with the help of a computer. Because it becomes easy, it is possible to display ethnic words without letters, display graphic information used for control signals in water and space, voice information to underwater workers and control signals for robot operation on the ground Available. It can also be used as a voice guidance board for blind people on the ground.

  In addition, by constructing a pair of right triangles of the character area and the tone area as a set, it is possible to express ethnic words or meanings that do not have letters, taking into account the tone, It is possible to provide voice guidance for station names and the like in words or meanings with tone. In addition, the provision of audio information to the underwater worker and the transmission of information can be expressed closer to the human language, taking into account the tone.

  The figure used in the information input method of the present invention is characterized in that a right triangle is used as a basic figure as a figure that is easy to read by a computer and easy to be handwritten by a person, and a pronunciation is symbolized for detailed expression. . The triangle is used because it is easy to identify with the circle. FIG. 1 shows a basic figure.

  In FIG. 1, a large right triangle (hereinafter referred to as a large right triangle) specifies the upper, lower, right and left sides of the triangle by setting the ratio of the lengths of two sides sandwiching a right angle to a value different from 1: 1, for example, 2: 1. Making it possible. Divide the three sides of this large right triangle into approximately equal parts (9 equals in Fig. 1) and connect the points corresponding to the equal parts of each side to form a similar small right triangle. To divide.

  Each corner of the large right triangle is filled with color (including black) and is used as a distinction signal from the large right triangle described later. 6 rows and 6 columns in the middle indicated by dotted lines in the vertical areas 3 to 8 and horizontal areas 2 to 7 of the small right triangle are used as vowel areas, and the remaining 2 diagonal lines and 1 bottom line are consonant areas. And For example, in FIG. 1, it is assumed that an English letter O is expressed by painting three places in the vowel area as shown in the figure, and an English letter T is written by painting two places in the consonant area as shown in the figure. As a result, the notation content represents TO (and).

  On the reading side, the figure filled with small right triangles is optically read as a bundle of information and input to the computer, and the figure is converted into sound based on the figure / speech correspondence information stored in the memory of the computer. And “sound”.

  FIG. 2 shows an embodiment in which a meaningful content is provided by arranging a plurality of these large right triangles. 2A, for example, as described with reference to FIG. 1, the sound of “to” is used, and the filled shape of the small right triangle in FIG. 2B is “ma”, and the sound of FIG. If the filled shape of the small right triangle is the “re” sound, the three large right triangles can be used to produce the three-letter sound “to rare”. The number of characters is not limited to three, and the necessary words can be expressed by preparing a large right triangle as many as the required number of characters.

  Therefore, if this graphic information is placed in a dangerous place such as off-limits, the visually handicapped person can read it with the optical reading means it holds, and the portable signal processor can perform graphic / audio conversion. By performing the process, it is possible to detect danger by voice. In addition, street signs, signs, building names, etc. are written with right triangle symbols, so that they can be captured as a camera image on the computer on behalf of a blind person, and the figure can be decoded by graphic / speech-compatible processing means. It is possible to output to a voice utterance device or the like.

  Next, with reference to FIG. 3, an embodiment will be described in which two large right-angled triangles are taken as a set, and a sound can be expressed in consideration of the tone. 3A, 3B, and 3C, the upper large right triangle indicates a character area, and the lower large right triangle is a tone area. Each corner of the character area is color-coded, and the tone area is color-coded and painted at the two corners of the base except for the vertex of the large right triangle, and is used for recognition recognition of the character area and the tone area.

  The upper right triangular character regions shown in FIGS. 3A, 3B, and 3C respectively represent “to”, “ma”, and “re” characters as shown in FIG. The tone area of the lower right triangle is a part representing an instruction symbol for the voice utterance device. In the example of FIG. 3A, the area (a) of the small right triangle is the pitch of the sound, the area (b) is the length (time) of the sound, and the area (c) is the sound intensity. The area (d) indicates a sound shape (inflection) instruction. The area (a) of the small right triangle in FIG. 3 (A) represents, for example, the tone of the pitch “mi”.

  Therefore, it is read by a computer as composite information of a large right triangle character area and a tone area, and converted into a specific character taking into account the tone, and in the example of FIG. And can be phonetic. Similarly, also in the tone area of FIGS. 3B and 3C, the area (a) of the small right triangle represents, for example, the tone pitches of “Fa” and “Fa”, respectively, and has tone. The letters “ma” and “re” are shown.

  3A, 3B, and 3C as a whole, it is possible to produce a three-letter phoneme of "Tare rare" with each tone. The number of characters is not limited to 3 characters, but by preparing as many graphic information as the required number of characters as a set of two upper and lower right triangles, it is possible to express the necessary words with tone, especially poetry, Suitable for expressions such as songs.

  It is necessary to make it easy to determine the top / bottom / left / right of the figure to be read for an underwater robot or a robot working in a place where it is difficult to determine a reference, such as outer space, regardless of the posture of the robot. Next, an embodiment suitable for graphic information in water and in outer space will be described with reference to FIG.

  In FIG. 4, the top of the large right triangle, the vertical region 2 of the small right triangle, and the base of the large right triangle are colored and painted in order to make it easy to determine the top, bottom, left, and right of the figure to be read. Moreover, the vertical region 5 of the small right triangle is colored and colored in the horizontal direction as an arrow notation. Then, FIG. 4A shows the information of “left arrow” by coloring the left side of the large right triangle, and FIG. 4B shows the right side of the large right triangle by coloring. Thus, the information is “right arrow”.

  In this way, since the information on the “left arrow” and the information on the “right arrow” can be expressed easily, the information is not limited to graphic information used for control signals in the water and in space. It can be used for operation control signals and audio information for underwater workers. It can also be used as a voice guidance board for blind people on the ground.

  In the character area, as shown in FIG. 1, the small right triangle at each vertex of the large right triangle is filled, and on the reading side, the large symbol is read by reading the filled symbol of the small right triangle at each vertex of the large right triangle. The size of a right triangle can be estimated. Further, if it is given in advance how many sides of the large right triangle are divided, the ratio of the lengths of the sides and the area of the small right triangle can be estimated. Then, by comparing with the filled area of each small right-angled triangle, it is possible to determine whether it is normally filled or dirty with dust.

  Then, which of the small right triangles is to be filled is preliminarily incorporated in the basic setting on the reading side based on whether a word is written or a simple instruction symbol is shown. In addition, by setting the inverted small right triangle with the base on the top, it is a part that does not fill, so even if there is an overfill, this is not normal, so it will not be included in the filled figure Processing can be performed.

  The information input method using the triangular figure of the present invention can be applied to various fields such as language display of ethnic groups without characters, information transmission to visually impaired people, operation command information of robots on the ground, underwater, and space. Applicable to.
