Description

入力装置、情報端末装置および入力システムInput device, information terminal device, and input system
　本発明は、入力操作をタッチパネルに指示する入力装置、入力装置からの入力操作を受け付ける情報端末装置および入力システムに関する。 The present invention relates to an input device that instructs a touch panel to perform an input operation, an information terminal device that receives an input operation from the input device, and an input system.
　スマートフォンまたはタブレット端末等、静電容量式タッチパネルの端末が多く出ているが、爪が長いユーザまたは指が太いユーザは、特に小さなボタンに対して指によるタッチ操作を行うのが難しい。 There are many capacitive touch panel terminals such as smartphones and tablet terminals. However, it is difficult for a user with a long nail or a user with a thick finger to perform a touch operation with a finger on a small button.
　そのため、指と同じ性質の導電性材料をペン先に配置した静電容量式タッチパネル用のスタイラス（ｓｔｙｌｕｓ）が作られている。導電性材料を指と同等の接触面積でパネルに接触させることにより、タッチパネル入力が可能である。ペン先には導電性ゴムまたは導電性スポンジ等が使われており、ペン先をタッチパネルに押し当てることにより接触面積を大きくしている（例えば、特許文献１の手書き文字入力装置参照）。 Therefore, a stylus for a capacitive touch panel in which a conductive material having the same property as that of a finger is arranged at the pen tip is made. Touch panel input is possible by bringing a conductive material into contact with the panel with a contact area equivalent to that of a finger. Conductive rubber or conductive sponge is used for the pen tip, and the contact area is increased by pressing the pen tip against the touch panel (see, for example, the handwritten character input device of Patent Document 1).
　また、タッチパネルと指との間に生じる静電容量の大きさは、タッチパネルと指との距離に反比例するので、この静電容量の変化を検出することにより、指の近接を検知する近接検知タッチパネルが開発されている。 In addition, since the magnitude of the capacitance generated between the touch panel and the finger is inversely proportional to the distance between the touch panel and the finger, the proximity detection touch panel that detects the proximity of the finger by detecting this change in capacitance. Has been developed.

　しかしながら、特許文献１では、指と同じ性質の導電性材料をペン先に配置した静電容量式タッチパネル用スタイラスは、導電性材料を指と同等の接触面積でタッチパネルに接触させる。このため、入力装置のペン先が太く、操作中（例えば筆記中）のユーザの視認性が良くないことがある。 However, in Patent Document 1, the capacitive touch panel stylus in which the conductive material having the same property as the finger is arranged at the pen tip makes the conductive material contact the touch panel with a contact area equivalent to that of the finger. For this reason, the pen tip of the input device may be thick and the visibility of the user during operation (for example, during writing) may not be good.
　また、静電容量式タッチパネル用スタイラスとタッチパネルとの接触面積が大きく摩擦抵抗が大きいため、入力装置のペンの滑りが悪く、書きづらく、操作性が劣化する。さらに、静電容量式タッチパネル用スタイラスは、接触面積の大小により筆圧を制御しているが、その制御がやりづらい。また、静電容量式タッチパネル用スタイラスに導電性のペン先を用いると、ユーザは入力装置のペン先がどの程度、検知面（タッチパネル）から離れているかが分かりづらいため、操作性が良くない。 Also, since the contact area between the capacitive touch panel stylus and the touch panel is large and the frictional resistance is large, the pen of the input device is difficult to slide, making it difficult to write and operability to deteriorate. Furthermore, the stylus for a capacitive touch panel controls the writing pressure depending on the size of the contact area, but it is difficult to control it. Further, when a conductive pen tip is used for the capacitive touch panel stylus, it is difficult for the user to know how far the pen tip of the input device is from the detection surface (touch panel), so the operability is not good.

　以下、本発明の各実施の形態にかかる入力装置、情報端末装置および入力システムについて、図面を参照して詳細に説明する。 Hereinafter, an input device, an information terminal device, and an input system according to each embodiment of the present invention will be described in detail with reference to the drawings.
　本発明の実施の形態１にかかる入力システムは、スタイラス（ｓｔｙｌｕｓ）と情報端末装置とで構成される。本実施の形態１では、この情報端末装置のアプリケーション処理部が、このスタイラスを入力装置として用いた手書き入力に従って動作している例を説明する。なお、手書き入力はアプリケーションの一例であって、このスタイラスを入力装置として利用するアプリケーションはこの例に限らない。 The input system according to the first embodiment of the present invention includes a stylus and an information terminal device. In the first embodiment, an example will be described in which the application processing unit of the information terminal device operates according to handwriting input using the stylus as an input device. Handwritten input is an example of an application, and an application that uses the stylus as an input device is not limited to this example.
　本発明の実施の形態１にかかる入力システムは、入力インタフェースとして静電容量式のタッチパネルを用いる。そして、このタッチパネルに対する入力装置であるスタイラスは、指と同等の特性を持つ導電性材料からなる導電部と、この導電部よりも細い非導電部とが接続して構成されている。なお、タッチパネルは、タッチスクリーン（Ｔｏｕｃｈｓｃｒｅｅｎ）と呼ばれる場合もある。 The input system according to the first embodiment of the present invention uses a capacitive touch panel as an input interface. A stylus that is an input device for the touch panel is configured by connecting a conductive portion made of a conductive material having characteristics equivalent to those of a finger and a non-conductive portion that is thinner than the conductive portion. Note that the touch panel may be referred to as a touch screen.
（実施の形態１）
　図１は、本実施の形態１にかかる入力装置であるスタイラス１０３の概略構成を示す図である。本実施の形態１にかかるスタイラス１０３は、導電部１０１と、先端部１０２とを備える。導電部１０１は、導電性材料によりペン軸状に形成される。導電部１０１は、タッチパネル２０１とスタイラス１０３との間の静電容量を変化させて、タッチパネル上の３次元座標を指定する。導電部１０１は、指と同等の特性の導電性材料、例えば、導電性ゴム、導電性樹脂、金属で形成される。 (Embodiment 1)
FIG. 1 is a diagram illustrating a schematic configuration of a stylus 103 that is an input device according to the first embodiment. The stylus 103 according to the first embodiment includes a conductive portion 101 and a tip portion 102. The conductive portion 101 is formed in a pen shaft shape from a conductive material. The conductive unit 101 changes the electrostatic capacitance between the touch panel 201 and the stylus 103 and designates three-dimensional coordinates on the touch panel. The conductive portion 101 is formed of a conductive material having characteristics equivalent to those of a finger, for example, conductive rubber, conductive resin, or metal.
　先端部１０２は、非導電性材料によりペン先状に形成される。先端部１０２は、導電部１０１の一端から連続し、導電部１０１が３次元座標を指定する際にタッチパネルに接触する。また、先端部１０２は、導電部１０１より細いので、ユーザはタッチパネル２０１の接触点を容易に視認できる。先端部１０２は、非導電性材料、例えばゴムまたは樹脂により細いペン先状に形成される。 The tip 102 is formed in a pen tip shape from a non-conductive material. The tip portion 102 is continuous from one end of the conductive portion 101 and contacts the touch panel when the conductive portion 101 designates a three-dimensional coordinate. Moreover, since the front-end | tip part 102 is thinner than the electroconductive part 101, the user can visually recognize the contact point of the touch panel 201 easily. The tip portion 102 is formed in a thin nib shape from a non-conductive material such as rubber or resin.
　ここで、先端部１０２は交換可能であり、ユーザは、先端部１０２を交換することで、書き易い筆圧でタッチパネル２０１上に手書き入力することができる。つまり、先端部１０２の素材を変更することで、スタイラス１０３は、筆圧を適宜変化させることができる。例えば、先端部１０２を硬い樹脂で形成する場合には、スタイラス１０３は鉛筆またはボールペンのような書き味をユーザに提供することができ、先端部１０２を弾力性のある樹脂やゴムで形成する場合には、毛筆のような書き味をユーザに提供することができる。 Here, the tip portion 102 is replaceable, and the user can input by handwriting on the touch panel 201 with a writing pressure that is easy to write by replacing the tip portion 102. That is, the stylus 103 can change the writing pressure as appropriate by changing the material of the tip portion 102. For example, when the tip portion 102 is formed of a hard resin, the stylus 103 can provide the user with a writing feel like a pencil or a ballpoint pen, and when the tip portion 102 is formed of an elastic resin or rubber. Can provide the user with a writing taste like a brush.
　図２は、本実施の形態１にかかるスタイラス１０３によりタッチパネル２０１に入力する場合の側面図である。情報端末装置は、タッチパネル２０１から一定距離離れた導電性材料で形成された導電部１０１をペン入力として検出する。なお、指をタッチパネル２０１に接触させると通常の接触検知型のタッチパネル入力になる。 FIG. 2 is a side view in the case of inputting to the touch panel 201 by the stylus 103 according to the first embodiment. The information terminal device detects the conductive part 101 formed of a conductive material that is a certain distance away from the touch panel 201 as a pen input. When a finger is brought into contact with the touch panel 201, normal touch detection type touch panel input is performed.
　すなわち、図２の場合、スタイラス１０３はタッチパネル２０１上の３次元座標として導電部１０１の先端点Ｐ１（ｘ１，ｙ１，ｚ１）を指定することができる。なお、３次元座標は、タッチパネル２０１の表面上にｘ，ｙ座標をとり、タッチパネル２０１の垂直方向にｚ座標をとる。 That is, in the case of FIG. 2, the stylus 103 can designate the tip point P1 (x1, y1, z1) of the conductive portion 101 as a three-dimensional coordinate on the touch panel 201. Note that the three-dimensional coordinates are x and y coordinates on the surface of the touch panel 201 and z coordinates in the vertical direction of the touch panel 201.
　図３は、本実施の形態１にかかるスタイラス１０３において、弾性を有する先端部１０２に筆圧をかけた状態を示す図である。先端部１０２がしなることによりタッチパネル２０１と導電性材料である導電部１０１との間の距離ｚ２が、先端部１０２がしなる前よりも近くなる。導電部１０１がタッチパネル２０１に近づくと、タッチパネル２０１は距離が短くなったと検知する。つまり、この距離が筆圧情報として用いられる。 FIG. 3 is a diagram illustrating a state in which writing pressure is applied to the elastic tip 102 in the stylus 103 according to the first embodiment. By bending the tip portion 102, the distance z2 between the touch panel 201 and the conductive portion 101 that is a conductive material becomes closer than before the tip portion 102 is bent. When the conductive unit 101 approaches the touch panel 201, the touch panel 201 detects that the distance has been shortened. That is, this distance is used as writing pressure information.
　例えば、後述する情報端末装置５０１のアプリケーション処理部５０２は、タッチパネル２０１と導電性材料である導電部１０１との間の距離ｚ２が短いほど、アプリケーションにおいて手書きされた文字の筆跡を太くすることができる。なお、後述する情報端末装置５０１のアプリケーション処理部５０２は、タッチパネル２０１と導電性材料である導電部１０１との間の距離ｚ２が短いほど、アプリケーションにおいて手書きされた文字の筆跡を細くしても良い。また、後述する情報端末装置５０１のアプリケーション処理部５０２は、タッチパネル２０１と導電性材料である導電部１０１との間の距離ｚ２が短いほど、アプリケーションにおいて手書きされた文字の筆跡の濃淡を濃くすることができる。なお、後述する情報端末装置５０１のアプリケーション処理部５０２は、タッチパネル２０１と導電性材料である導電部１０１との間の距離ｚ２が短いほど、アプリケーションにおいて手書きされた文字の筆跡の濃淡を薄くしても良い。 For example, the application processing unit 502 of the information terminal device 501 described later can increase the handwriting of characters handwritten in the application as the distance z2 between the touch panel 201 and the conductive unit 101 that is a conductive material is shorter. . Note that the application processing unit 502 of the information terminal device 501 to be described later may reduce the handwriting of characters handwritten in the application as the distance z2 between the touch panel 201 and the conductive unit 101 that is a conductive material is shorter. . Further, the application processing unit 502 of the information terminal device 501 described later increases the density of handwriting of characters handwritten in the application as the distance z2 between the touch panel 201 and the conductive unit 101 that is a conductive material is shorter. Can do. Note that the application processing unit 502 of the information terminal device 501 described later reduces the handwriting density of characters handwritten in the application as the distance z2 between the touch panel 201 and the conductive unit 101 that is a conductive material is shorter. Also good.
　図４は、本実施の形態１にかかるスタイラス１０３の別の構造を示す図である。本実施の形態１のスタイラス１０３は、非導電性の先端部１０２が導電部１０１にバネ４０１によって外向きの付勢力が与えられているので、先端部１０２がそれに連続する導電部１０１に筆圧に応じて引っ込み、導電部１０１の検出高さ（距離）ｚを筆圧に応じて変化させることができる。図３同様、導電部１０１の検出高さ（距離）ｚは筆圧情報として用いられる。例えば、後述する情報端末装置５０１のアプリケーション処理部５０２は、導電部１０１の検出高さｚが短いほど、アプリケーションにおいて手書きされた文字の筆跡を太くすることができる。なお、後述する情報端末装置５０１のアプリケーション処理部５０２は、導電部１０１の検出高さｚが短いほど、アプリケーションにおいて手書きされた文字の筆跡を細くしても良い。また、後述する情報端末装置５０１のアプリケーション処理部５０２は、導電部１０１の検出高さｚが短いほど、アプリケーションにおいて手書きされた文字の筆跡の濃淡を濃くすることができる。なお、後述する情報端末装置５０１のアプリケーション処理部５０２は、導電部１０１の検出高さｚが短いほど、アプリケーションにおいて手書きされた文字の筆跡の濃淡を薄くしても良い。 FIG. 4 is a diagram showing another structure of the stylus 103 according to the first embodiment. In the stylus 103 according to the first embodiment, the non-conductive tip portion 102 is applied with an outward biasing force to the conductive portion 101 by the spring 401, so that the tip portion 102 applies a writing pressure to the conductive portion 101 continuous thereto. The detected height (distance) z of the conductive portion 101 can be changed according to the writing pressure. As in FIG. 3, the detected height (distance) z of the conductive portion 101 is used as writing pressure information. For example, the application processing unit 502 of the information terminal device 501 described later can increase the handwriting of characters handwritten in the application as the detection height z of the conductive unit 101 is shorter. Note that the application processing unit 502 of the information terminal device 501 to be described later may make the handwriting of the character handwritten in the application thinner as the detection height z of the conductive unit 101 is shorter. In addition, the application processing unit 502 of the information terminal device 501 described later can darken the handwriting of characters handwritten in the application as the detection height z of the conductive unit 101 is shorter. Note that the application processing unit 502 of the information terminal device 501 described later may make the handwriting of characters handwritten in the application lighter or darker as the detection height z of the conductive unit 101 is shorter.
　上述のように、本実施の形態１のスタイラス１０３は、先端部１０２が導電部１０１より細いので、操作中（筆記中）の視認性が良く、スタイラス１０３の先端部１０２のペン先の滑りが良く、筆圧の制御が容易となり、ユーザに手書きを簡易に行わせることができる。また、本実施の形態１のスタイラス１０３は、導電部１０１が３次元座標を指定する際に先端部１０２がタッチパネル２０１に接触するので、安定した入力操作が可能である。 As described above, the stylus 103 according to the first embodiment has a tip 102 that is thinner than the conductive part 101, so that the visibility during operation (during writing) is good, and the tip of the stylus 103 slides at the tip of the stylus 103. The writing pressure can be easily controlled and the user can easily perform handwriting. Further, the stylus 103 according to the first embodiment can perform a stable input operation because the distal end portion 102 contacts the touch panel 201 when the conductive portion 101 designates a three-dimensional coordinate.
　図５は、本実施の形態１にかかる情報端末装置５０１の機能ブロックを示す図である。本実施の形態１の情報端末装置５０１は、静電容量式のタッチセンサ（タッチパネル２０１）としてのセンサ部５０９と、センサ部５０９、即ち、タッチセンサ（タッチパネル２０１）からの出力情報を取得するセンサ情報取得部５０８と、タッチパネル２０１からスタイラス１０３の導電部１０１までの距離情報（検出高さ）ｚを、センサ情報取得部５０８により取得されたセンサ情報を基に導出する高さ算出部５０７と、高さ情報を筆圧値に変換する筆圧変換部５０５と、タッチパネル２０１の導電部１０１のタッチパネル２０１上のＸＹ座標値を、センサ情報を基に導出する座標算出部５０６と、算出されたＸＹ座標値をペン先の位置に合うよう補正する座標補正部５０４と、ＸＹ座標情報と筆圧情報をアプリケーション処理部５０２に通知する入力情報通知部５０３と、入力情報通知部５０３からの出力を基にして筆圧に応じた手書き描画などの処理を行うアプリケーション処理部５０２とを備える。 FIG. 5 is a diagram illustrating functional blocks of the information terminal device 501 according to the first embodiment. The information terminal device 501 according to the first embodiment includes a sensor unit 509 as a capacitive touch sensor (touch panel 201), and a sensor unit 509, that is, a sensor that acquires output information from the touch sensor (touch panel 201). An information acquisition unit 508; a height calculation unit 507 for deriving distance information (detection height) z from the touch panel 201 to the conductive unit 101 of the stylus 103 based on the sensor information acquired by the sensor information acquisition unit 508; A writing pressure conversion unit 505 that converts height information into writing pressure values, a coordinate calculation unit 506 that derives XY coordinate values on the touch panel 201 of the conductive unit 101 of the touch panel 201 based on sensor information, and a calculated XY A coordinate correction unit 504 that corrects the coordinate value to match the position of the pen tip, and an XY coordinate information and writing pressure information are converted into an application processing unit 502. It includes an input information notification unit 503 to be notified, the application processing unit 502 which performs processing such as handwritten drawing corresponding to pen pressure based on output from the input information notifying unit 503.
　センサ部５０９は、タッチパネル２０１のＸ方向およびＹ方向にそれぞれ短冊状の電極が配置されたＸ，Ｙマトリックス型タッチパネルを構成する。すなわち、センサ部５０９は、Ｘ方向の近接位置を検出するためにＸ方向に並べて配置されたＹ方向と平行な複数のＸ方向センサ電極と、Ｙ方向の近接位置を検出するためにＹ方向に並べて配置されたＸ方向と平行な複数のＹ方向センサ電極から構成される。なお、センサ電極パターンはこの構成に限定されない。  The sensor unit 509 constitutes an X, Y matrix type touch panel in which strip electrodes are arranged in the X direction and the Y direction of the touch panel 201, respectively. That is, the sensor unit 509 includes a plurality of X-direction sensor electrodes arranged in parallel with the Y direction in order to detect the proximity position in the X direction, and the Y direction in order to detect the proximity position in the Y direction. It is composed of a plurality of Y-direction sensor electrodes arranged side by side and parallel to the X direction. The sensor electrode pattern is not limited to this configuration.
　ここで、タッチパネル２０１に、スタイラス１０３が近接するとセンサ出力値が得られる仕組みについて簡単に説明する。本実施の形態１ではスタイラス１０３の導電部１０１とタッチパネル２０１に配置されたセンサ電極との間の静電容量を検出する方法を用いて導電部１０１の近接を検出する。 Here, a mechanism for obtaining a sensor output value when the stylus 103 comes close to the touch panel 201 will be briefly described. In the first embodiment, the proximity of the conductive portion 101 is detected by using a method for detecting the capacitance between the conductive portion 101 of the stylus 103 and the sensor electrode disposed on the touch panel 201.
　具体的には、タッチパネル２０１に配置されたＸ方向センサ電極およびＹ方向センサ電極に順次信号検出用の交流電圧を印加する。タッチパネル２０１に導電部１０１が近接すると、タッチパネル２０１のＸ方向センサ電極およびＹ方向センサ電極と導電部１０１との間に微小な静電容量が生じる。センサ電極に印加した交流電圧によって、この微小な静電容量を通してセンサ電極から導電部１０１へ微弱な電流が流れる。このとき、センサ電極の出力電圧を観測すると、導電部１０１が近接している周囲のセンサ電極は上述のように電流が流れるために、観測される出力電圧が低下する。この出力電圧の低下の大きさを各センサ電極の出力値とする。なお、センサ部５０９としてのタッチセンサ（タッチパネル２０１）の検出はこの方法に限らない。 Specifically, an AC voltage for signal detection is sequentially applied to the X direction sensor electrode and the Y direction sensor electrode arranged on the touch panel 201. When the conductive part 101 comes close to the touch panel 201, a minute capacitance is generated between the X direction sensor electrode and the Y direction sensor electrode of the touch panel 201 and the conductive part 101. Due to the AC voltage applied to the sensor electrode, a weak current flows from the sensor electrode to the conductive portion 101 through this minute capacitance. At this time, when the output voltage of the sensor electrode is observed, since the current flows in the surrounding sensor electrodes close to the conductive portion 101 as described above, the observed output voltage decreases. The magnitude of this decrease in output voltage is taken as the output value of each sensor electrode. The detection of the touch sensor (touch panel 201) as the sensor unit 509 is not limited to this method.
　タッチパネル２０１と導電部１０１との間に生じる静電容量の大きさは、タッチパネル２０１と導電部１０１との距離に反比例する。そのため、導電部１０１が最も接近している位置のセンサ電極の出力電圧が最も大きく低下する。即ち、最も大きなセンサ出力値となる。 The size of the capacitance generated between the touch panel 201 and the conductive part 101 is inversely proportional to the distance between the touch panel 201 and the conductive part 101. Therefore, the output voltage of the sensor electrode at the position where the conductive portion 101 is closest is greatly reduced. That is, the maximum sensor output value is obtained.
　センサ部５０９は、導電部１０１がタッチパネル２０１に近接した場合に、タッチパネル２０１のＸ方向センサ電極およびＹ方向センサ電極が出力する出力信号から各センサ出力値を求める。そして、これらのセンサ出力値から導電部１０１のＸＹ座標およびＺ座標を取得する。 The sensor unit 509 obtains each sensor output value from the output signals output from the X direction sensor electrode and the Y direction sensor electrode of the touch panel 201 when the conductive unit 101 is close to the touch panel 201. Then, the XY coordinate and Z coordinate of the conductive portion 101 are acquired from these sensor output values.
　図６は、本実施の形態１にかかるスタイラス１０３において、柔らかいペン先のような先端部１０２に筆圧をかけた状態の拡大図である。センサ情報取得部５０８は、スタイラス１０３の導電部１０１の先端点Ｐ１（ｘ１，ｙ１，ｚ１）をセンサ情報として取得するが、このセンサ情報をそのままアプリケーション処理部５０２に通知すると、ＸＹ座標情報（ｘ１，ｙ１）に対応するタッチパネル２０１上の点Ｐ２（ｘ１，ｙ１，０）に手書き描画が行われる。 FIG. 6 is an enlarged view of the stylus 103 according to the first embodiment in a state where the pen pressure is applied to the tip 102 such as a soft pen tip. The sensor information acquisition unit 508 acquires the tip point P1 (x1, y1, z1) of the conductive unit 101 of the stylus 103 as sensor information. When this sensor information is directly notified to the application processing unit 502, the XY coordinate information (x1 , Y1), handwritten drawing is performed at a point P2 (x1, y1, 0) on the touch panel 201 corresponding to.
　実際にスタイラス１０３の先端部１０２がタッチパネル２０１に接触しているのは点Ｐ４（ｘ４，ｙ４，０）であるので、この点Ｐ４（ｘ４，ｙ４，０）に手書き描画が行われるように座標補正部５０４においてＸＹ座標情報を補正する。 Since the point P4 (x4, y4, 0) is actually in contact with the touch panel 201, the tip 102 of the stylus 103 is coordinated so that handwritten drawing is performed at this point P4 (x4, y4, 0). The correction unit 504 corrects the XY coordinate information.
　座標補正部５０４では、実際の検出点Ｐ２（ｘ１，ｙ１，０）の過去の履歴点Ｐ３（ｘ２，ｙ２，０）と、Ｐ２とＰ３に対応するｚ座標ｚ２，ｚ３を利用して、描画位置をペン先の接点Ｐ４に補正する。これにより、ユーザは、スタイラス１０３によって手書き入力する場合にペン先に追従する手書き描画を行うことができる。 The coordinate correction unit 504 draws using the past history point P3 (x2, y2, 0) of the actual detection point P2 (x1, y1, 0) and the z coordinates z2, z3 corresponding to P2 and P3. The position is corrected to the pen point contact P4. Thereby, the user can perform handwriting drawing that follows the pen tip when handwriting is input by the stylus 103.
　図７は、本実施の形態１にかかるスタイラス１０３において、硬いペン先のような先端部１０２により手書き描画を行う状態の拡大図である。本実施の形態１においてもセンサ情報取得部５０８は、スタイラス１０３の導電部１０１の先端点Ｐ１（ｘ１，ｙ１，ｚ１）をセンサ情報として取得するので、このセンサ情報のままでは、ペン先と描画位置にずれが生じる。 FIG. 7 is an enlarged view of the stylus 103 according to the first embodiment in a state where handwritten drawing is performed with the tip 102 such as a hard pen tip. Also in the first embodiment, the sensor information acquisition unit 508 acquires the tip point P1 (x1, y1, z1) of the conductive unit 101 of the stylus 103 as sensor information. Deviation occurs in position.
　そこで、本実施の形態１では、スタイラス１０３の導電部１０１の先端点Ｐ１（ｘ１，ｙ１，ｚ１）と、導電部１０１の他の点Ｐ２（ｘ２，ｙ２，ｚ２）のセンサ情報からスタイラス１０３の傾きを計算し、その傾きから先端部１０２がタッチパネル２０１に接触している点Ｐ３（ｘ３，ｙ３，０）を求める。 Therefore, in the first embodiment, the stylus 103 is detected from the sensor information of the tip point P1 (x1, y1, z1) of the conductive portion 101 of the stylus 103 and the other point P2 (x2, y2, z2) of the conductive portion 101. An inclination is calculated, and a point P3 (x3, y3, 0) where the tip portion 102 is in contact with the touch panel 201 is obtained from the inclination.
　また、柔らかいペン先のような先端部１０２に筆圧をかけた場合は、スタイラス１０３の傾きとともに、点Ｐ１と点Ｐ２のｚ座標ｚ１，ｚ２を利用して、ペン先の接点Ｐ３を求める。これにより、手書き入力する場合にペン先に追従する手書き描画を行うことができる。 Further, when a pen pressure is applied to the tip 102 such as a soft pen tip, the pen point contact P3 is obtained using the z coordinates z1 and z2 of the point P1 and the point P2 together with the inclination of the stylus 103. Thereby, handwritten drawing that follows the pen tip when handwritten input can be performed.
　本実施の形態１のスタイラス１０３、情報端末装置５０１および入力システムによれば、先端部１０２が導電部１０１より細いので、操作中（筆記中）の視認性が良く、ペン先の滑りが良く、筆圧の制御が容易となり、ユーザに手書きを簡易に行わせることができる。また、導電部１０１が３次元座標を指定する際に先端部１０２がタッチパネル２０１に接触するので、安定した入力操作が可能である。さらに、導電部１０１とタッチパネル２０１との間の距離情報ｚを導出し、距離情報ｚを筆圧値に変換するので、筆圧制御が容易になる。 According to the stylus 103, the information terminal device 501, and the input system according to the first embodiment, the tip portion 102 is thinner than the conductive portion 101, so the visibility during operation (writing) is good, and the tip of the pen tip is good. The writing pressure can be easily controlled, and the user can easily perform handwriting. In addition, since the tip portion 102 contacts the touch panel 201 when the conductive portion 101 designates three-dimensional coordinates, a stable input operation is possible. Furthermore, since the distance information z between the conductive part 101 and the touch panel 201 is derived and the distance information z is converted into a writing pressure value, writing pressure control is facilitated.
　なお、本実施の形態１では、スタイラス１０３が手書き入力のための入力装置として説明したが、本発明は、パラメータを変化させるための入力装置としてスタイラス１０３が使用されるアプリケーションすべてに適用できる。 In the first embodiment, the stylus 103 has been described as an input device for handwriting input. However, the present invention can be applied to all applications in which the stylus 103 is used as an input device for changing parameters.
　なお、タッチパネル２０１は、その入力インタフェースとして、静電容量式のセンサ部５０９を備えるものとして説明したが、センサ方式はこれに限らない。 The touch panel 201 has been described as including the capacitive sensor unit 509 as its input interface, but the sensor system is not limited thereto.
　実施の形態１の入力装置はスタイラス１０３に限定されず、例えば、入力装置は、例えば実施の形態１の情報端末装置がゲーム装置である場合に、ゲーム装置にユーザの入力操作を指示するゲームコントローラでも良い。入力装置としてのゲームコントローラに関する先行技術としては、例えば下記参考特許文献１のゲームコントローラが知られている。 The input device according to the first embodiment is not limited to the stylus 103. For example, when the information terminal device according to the first embodiment is a game device, the input device is a game controller that instructs the game device to perform an input operation by the user. But it ’s okay. As a prior art related to a game controller as an input device, for example, a game controller disclosed in Reference Document 1 below is known.
　（参考特許文献１）　日本国特開２００６－１４９９８５号公報 (Reference Patent Document 1) Japanese Unexamined Patent Publication No. 2006-149985
　参考特許文献１のゲームコントローラは、押圧された位置に応じた位置情報を出力するタッチパネルを有し、タッチパネルから出力された位置情報に基づいてゲーム処理を実行するゲーム装置に装着される。このゲームコントローラは、タッチパネルを押圧するための押圧部と、押圧部を移動させる操作を行う操作部とを有し、タッチパネルを押圧する位置を変更可能に押圧部を支持する。 The game controller of Reference Patent Document 1 has a touch panel that outputs position information corresponding to a pressed position, and is attached to a game device that executes game processing based on the position information output from the touch panel. This game controller includes a pressing unit for pressing the touch panel and an operation unit for performing an operation of moving the pressing unit, and supports the pressing unit so that the position at which the touch panel is pressed can be changed.
　参考特許文献１では、ゲーム装置のタッチパネル（画面）がゲームコントローラによって被せられ、特定用途（例えばゲーム）に限ったゲーム装置に対するゲームコントローラとしては有用であると考えられる。しかしながら、情報端末装置がゲーム用途ではなく汎用的な用途に対応可能な電子機器（例えばスマートフォン）である場合には、参考特許文献１のゲームコントローラが取り付けられると、ユーザは、ゲーム以外の用途において自己の入力操作を指示するときにゲームコントローラを一旦取り外す必要があり、ユーザの操作性が劣化する可能性がある。 In Reference Patent Document 1, it is considered that a touch panel (screen) of a game device is covered by a game controller and is useful as a game controller for a game device limited to a specific application (for example, a game). However, when the information terminal device is an electronic device (for example, a smartphone) that can be used for a general purpose rather than a game, when the game controller of Reference Patent Document 1 is attached, the user can It is necessary to remove the game controller once when instructing its own input operation, and the operability of the user may be deteriorated.
　そこで、実施の形態２では、情報端末装置の一例としてスマートフォンを用いて説明し、ユーザが情報端末装置においてゲームする場合に、情報端末装置の画面上に取り付けられた入力装置としてのゲームコントローラを用いて、ゲーム内容の視認性を向上させると共に、ゲーム以外の汎用的な用途にも利用可能にさせ、快適な操作性をユーザに享受させる入力装置および情報端末装置の例を説明する。 Therefore, in Embodiment 2, a smartphone is used as an example of an information terminal device, and when a user plays a game on the information terminal device, a game controller as an input device attached on the screen of the information terminal device is used. An example of an input device and an information terminal device that improve the visibility of game content and that can be used for general purposes other than games and that allows the user to enjoy comfortable operability will be described.
（実施の形態２）
　実施の形態１では、入力装置としてのスタイラス１０３の動作点、即ち、ユーザの入力操作をタッチパネル２０１に指示するときのタッチパネル２０１に対するスタイラス１０３の位置は、導電部１０１の先端点Ｐ１（ｘ１，ｙ１，ｚ１）であった（図２参照）。 (Embodiment 2)
In the first embodiment, the operating point of the stylus 103 as an input device, that is, the position of the stylus 103 with respect to the touch panel 201 when instructing the user's input operation to the touch panel 201 is the tip point P1 (x1, y1) of the conductive portion 101. , Z1) (see FIG. 2).
　同様に、本実施の形態２では、入力装置としてのゲームコントローラ１０３Ａの動作点、即ち、ユーザの入力操作をタッチパネル２０１に指示するときのタッチパネル２０１に対するゲームコントローラ１０３Ａの位置は、ゲームコントローラ１０３Ａの導電部１０４と先端部１０２Ａとの接合部１０７である（図８参照）。 Similarly, in the present second embodiment, the operating point of the game controller 103A as an input device, that is, the position of the game controller 103A with respect to the touch panel 201 when instructing the user's input operation to the touch panel 201, is the conductivity of the game controller 103A. This is a joint portion 107 between the portion 104 and the tip portion 102A (see FIG. 8).
　図８は、本実施の形態２にかかる入力装置であるゲームコントローラ１０３Ａの概略構成を示す図である。本実施の形態２にかかるゲームコントローラ１０３Ａは、接触部１０６と、先端部１０２Ａと、導電部１０４と、操作部１０５とを備える。 FIG. 8 is a diagram showing a schematic configuration of a game controller 103A which is an input device according to the second embodiment. The game controller 103A according to the second embodiment includes a contact part 106, a tip part 102A, a conductive part 104, and an operation part 105.
　接触部１０６は、タッチパネル２０１に接触又は固定される接着点としての機能を有し、例えば、透明の非導電性材料（吸盤１０８またはシール（不図示）等）により構成される。また、本実施の形態２では、接触部１０６は、図１０または図１２に示すように、タッチパネル２０１上において固定されている。 The contact part 106 has a function as an adhesion point to be contacted or fixed to the touch panel 201, and is made of, for example, a transparent non-conductive material (such as a suction cup 108 or a seal (not shown)). In the second embodiment, the contact portion 106 is fixed on the touch panel 201 as shown in FIG. 10 or FIG.
　先端部１０２Ａは、非導電性材料（例えば、ゴムまたは樹脂）によりペン先状に形成され、一端が接触部１０６に接合し、他端が接合部１０７を介して導電部１０４に接合している。先端部１０２Ａは導電部１０４および操作部１０５よりも細い形状を有するため、ユーザは導電部１０４または操作部１０５を動かしてゲームを行っている間でも画面ＤＰに表示されている内容の視認性を劣化させることがない。 The tip portion 102 </ b> A is formed in a pen tip shape with a non-conductive material (for example, rubber or resin), one end is joined to the contact portion 106, and the other end is joined to the conductive portion 104 via the joint portion 107. . Since the distal end portion 102A has a shape narrower than that of the conductive portion 104 and the operation portion 105, the user can view the content displayed on the screen DP even while the user is moving the conductive portion 104 or the operation portion 105 to play the game. There is no deterioration.
　また、先端部１０２Ａの長さは、ゲームコントローラ１０３Ａがタッチパネル２０１に対して垂直な方向に固定された場合に（図１２参照）、導電性材料により形成された接合部１０７（後述参照）がタッチパネル２０１によって近接が検知される時の長さまたは近接が検知されなくなる時の長さである。 Further, the length of the tip 102A is such that when the game controller 103A is fixed in a direction perpendicular to the touch panel 201 (see FIG. 12), the joint 107 (see below) formed of a conductive material is touch panel. The length when proximity is detected by 201 or the length when proximity is not detected.
　ここで、先端部１０２Ａの長さはゲームコントローラ１０３Ａがタッチパネル２０１に対して垂直な方向に固定された場合に（図１２参照）、導電性材料により形成された接合部１０７（後述参照）がタッチパネル２０１によって近接が検知される時の長さであるとする。この場合、情報端末装置５０１Ａは、接触部１０６がタッチパネル２０１上に固定され、ゲームコントローラ１０３Ａがタッチパネル２０１に対して垂直な方向から所定方向に傾けられた場合に、傾けられたときの接合部１０７の位置に対応するタッチパネル２０１上の位置のＸＹ座標値と、接触部１０６がタッチパネル２０１上において固定されている位置のＸＹ座標値とを基に、ゲームコントローラ１０３Ａの傾けられた角度を求めることができる。 Here, when the game controller 103A is fixed in a direction perpendicular to the touch panel 201 (see FIG. 12), the tip portion 102A is the length of the joint 107 (see below) formed of a conductive material. It is assumed that this is the length when proximity is detected by 201.
