Abstract

PURPOSE:To simultaneously perform the inputs of characters and graphics in a computer, leaving handwritings on paper by using a handwriting writing means such as normal pen and pencil by a user by making a device have a constitution that the surrounding of the tip of a pen is always continued to be monitored, uniting the device with a writing tool in a body, and each operation while a character is written is decided. CONSTITUTION:When a user writes characters on paper, etc., the device body 1 coupled with an arbitrary pencil, etc., operates together with the pencil. By the operation, the acceleration signals Sx and Sy of an X-axis and a Y-axis are detected by X-axis and Y-axis acceleration sensors 12 and 13. When a double integration is performed for the signals in a signal double integration part 15 after the signals are amplified in an amplification part 14, the locus of a handwriting is restored and the written character is recognized in a character recognition part 16. The recognized character is transmitted from a signal transmission part 17 to the outside by radio and infrared ray, etc., by a character code and an existing computer provided with a reception part receives the transmission. The down and up, etc., of the pencil on paper which is required for the double integration of the signal double integration part 15, the decision processings of various kinds of operations and the processing of timing, etc., are performed in a central processing part 19.

Description

【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は、筆記具等による文字や図形等の筆跡情報をコンピュータに入力する際、書き込み用に供される筆先動作判定処理方法及びその実施に直接使用するモニタ付文字入力装置に関するものである。 The present invention relates, when inputting handwriting information such as characters and figures according to a writing instrument to a computer, brush point operation determination processing method and the monitor with the character input directly used for the implementation is subjected to write to an apparatus.

【0002】 [0002]

【従来の技術】従来、文字や図形をコンピュータに入力するために、キーボードやマウス、タブレット等があるが、より携帯性に優れた入力装置として、ペンに一体内蔵した加速度センサの信号出力を2重積分処理するなどして、ユーザがペンで書いた文字や図形の軌道をコンピュータに入力する装置が数々提案されている(特開平3 Conventionally, in order to input characters and graphics on a computer, a keyboard and a mouse, there is a tablet or the like, as an input device having more excellent portability, the signal output of the acceleration sensor with a built integrally into the pen 2 such as by heavy integration process, a user device for inputting trajectory of characters and figures written with a pen on a computer has been proposed a number (JP 3
−156519号,特開平4−195321号,特開平4−256009号,特開平4−282717号等)。 No. -156519, JP-A-4-195321, JP-A-4-256009, JP-A-4-282717, etc.).

【0003】 [0003]

【発明が解決しようとする課題】こうした加速度センサ内蔵ペンの問題は、通常我々がさまざまな手書き筆記手段たる万年筆やシャープペンやマジックペンや水性ペンや絵筆や毛筆やボールペンや鉛筆等の種々の好みの種類、種々の書き味の筆記具としてのペンを使い分けているのに対して、固定化された特定のペンにしばられるという問題があった。 THE INVENTION Problems to be Solved] of these acceleration sensor built-in pen problem, usually we have a variety of handwriting writing means serving as a fountain pen or a sharp pen or magic pen or aqueous pen or paintbrush or brush or ball-point pen and a variety of favorite pencil, etc. type, whereas known by different pen as a writing instrument of various writing feeling, there is a problem that is bound to the particular pen immobilized.

【0004】また、加速度センサ内蔵ペンで、先端に装着したボールペンで紙にインクで書きながら、加速度信号を処理してペンの軌道をコンピュータに入力する(特開平4−282717号)技術も提案されているが、いずれにしても専用のペンを必要とし、ペンの交換は不可能であった。 Further, the acceleration sensor built pen while writing with ink on paper with a ballpoint pen attached to the distal end, it processes the acceleration signal to enter the trajectory of the pen to the computer (JP 4-282717) technology is proposed and that is, any case require a dedicated pen even, exchange of pen was impossible.

【0005】さらに、ペンを把持した時のセンサの軸方向をわかりやすくするために、ぺンの断面を逆三角形にしたり(特開昭62−140130号)する技術があるが、通常のペンと違って把持しにくいという問題があった。 Furthermore, for clarity in the axial direction of the sensor at the time of gripping the pen, there is a cross-section of pen reversed triangle or (JP 62-140130) technology, an ordinary pen there has been a problem that it is difficult to grip different. こうした問題を解決するために、ペンにバネやネジで結合した装置筺体に加速度センサを内蔵した入力装置によって、任意のペンが使えて、かつペンを把持した時に加速度センサの軸方向が自然にかつ強制的に決められる先願発明がある。 To solve these problems, the input device including an acceleration sensor device housing coupled by a spring or a screw to the pen, and can use any pen, and naturally and axial acceleration sensor when gripping the pen is forcibly decided be prior invention.

【0006】しかし、ペンそのものに加速度センサを内蔵する手段では、ペン軸に感圧センサを内蔵するなどして、ペンの紙や机面等へのアップ、ダウン動作が検出できたのに対して(特開平3−156519号)、ペンにバネやネジで結合した装置筺体に加速度センサを内蔵した入力装置では、ペンそのものをいじることができないために、ペン軸方向である三次元立体座標軸のZ軸にも加速度センサを内蔵して、ペンのアップ、ダウン動作を検出する必要があった。 However, the means for a built-in acceleration sensor on the pen itself, such as by incorporating a pressure sensor in the penholder, pen paper and up to a desk surface or the like, while the down operation can be detected (JP-a-3-156519), an input device including an acceleration sensor device housing coupled by a spring or screw the pen, because of the inability to fiddle with pen itself, Z three-dimensional coordinate axes is pen axis also built acceleration sensor to the shaft, it is necessary to detect pen up, down operation.

【0007】しかしこの方法では紙等へペンが接触するときに、充分なZ軸方向(図2座標軸参照)の変位や衝撃がないと、ペンのダウン動作がなかなか検出するのが困難という問題があった。 However, when the pen is in contact to the paper or the like in this manner, when sufficient Z-axis direction without displacement or shock (Figure 2 coordinate reference), a problem that difficult to detect pen-down operation is quite the there were. また、ペンの紙等からのアップ動作では、さらにZ軸方向の衝撃は小さいので、ペンの紙等からのアップ動作を検出するのがさらに困難であった。 Further, the up operation from the pen, such as paper, because further Z-axis direction of the impact is small, to detect up operation from the pen, such as paper, it was more difficult.

【0008】ここにおいて、本発明が解決すべき主要な目的は、次に列挙する通りである。 [0008] In this case, the primary objective the present invention is to provide a then listed as. 本発明の第1の目的は、加速度センサ内蔵のコンピュータへの文字や図形の入力装置において、ユーザが好みの任意の既存の通常のペンや鉛筆等の手書き筆記手段を選んで、紙に筆跡を残しながら、コンピュータへの文字や図形の入力が同時にできる筆先各種動作判定処理方法及びモニタ付筆跡情報入力装置を提供せんとするものである。 A first object of the present invention, the input device of the characters and figures to the acceleration sensor built in the computer, the user select the handwritten writing means such as any existing ordinary pen or pencil preference, handwriting on paper leaving while, in which input of characters and figures to a computer St. provide brush tip various operation determination processing method and the monitor with the handwriting information input device simultaneously.

【0009】本発明の第2の目的は、ペンの断面形状を逆三角形等にしたりして把持しにくくなること無しに、 A second object of the present invention, without becoming difficult to grip or the pen sectional shape in an inverted triangle, etc.,
既存の任意の筆記具を把持した時に加速度センサ内蔵装置によるコンピュータへの文字や図形に入力が同時にでき、かつ任意の筆記具の紙へのアップ,ダウン動作等の検出が確実にできる筆先各種動作判定処理方法及びモニタ付筆跡情報入力装置を提供せんとするものである。 An acceleration sensor built device input to characters and graphics to the computer by can be simultaneously and up to any of the writing instrument of the paper, brush point various operations determination process detection of down operation and the like can be reliably when holding the existing any writing instrument there is provided St. methods and monitoring with handwriting information input device.
