Abstract
Description
本発明は、スイッチが配置された機器の表面に対して、操作者が手を接近させて入力操作を行う場合に、その接近のしかたとして、操作者の手を左右に振ったり、上下に振ったりするなどに応じて多種な入力を行う非接触入力装置に関し、更に詳しくは、静電容量検出方式により例えば、液晶表示部上にスイッチを配置する場合には、液晶表示部の表示を妨げない透明な、スイッチを表面に配置して、操作者の手を上下左右に動かす事で、スイッチに接近する操作を検出する非接触入力装置に関する。 According to the present invention, when an operator performs an input operation with a hand approaching the surface of a device on which a switch is arranged, the operator's hand is swung left and right or up and down as a method of approach. More specifically, the present invention relates to a non-contact input device that performs various inputs in response to, for example, a capacitance detection method, for example, when a switch is arranged on a liquid crystal display unit, the display of the liquid crystal display unit is not hindered. The present invention relates to a non-contact input device that detects an operation approaching a switch by disposing a transparent switch on the surface and moving an operator's hand up, down, left, or right.
近年、小型化が求められる携帯電話機などのポータブル機器では、操作データを入力するために、ポータブル機器の筐体表面に設けられる入力操作領域が限られ、狭い入力操作領域を押圧して入力操作を行うことが困難となっている。またある程度広い入力操作領域があっても、ポータブル機器のデザインの関係で入力を行うスイッチの存在を意識させない為に、透明化させる等で、入力手段の多様化と多機能化を図り、操作性を向上させた薄型の電子機器に好適な入力検知装置が求められている。
そこで、非接触検出手段の検出部を透明として、ケースへ操作体を接近させただけで入力操作を検出する非接触検出手段を有する非接触入力装置が提案されている。
従来知られている静電容量検出方式の非接触入力装置では、自発光型素子であるＬＥＤで、表示部として構成されるユニットの上に透明保持板を取り付け、透明保持板の裏面に配置された透明電極が引き出しパターンによって、静電容量検出回路に接続され、透明電極とその周囲との静電容量の変化を監視している。
In recent years, portable devices such as mobile phones that require miniaturization have limited input operation areas provided on the surface of the casing of the portable device in order to input operation data. It has become difficult to do. In addition, even if there is a wide input operation area, in order not to be aware of the existence of a switch that performs input due to the design of the portable device, the input means can be diversified and multifunctional by making it transparent, etc. There is a demand for an input detection device suitable for a thin electronic device with improved performance.
In view of this, a non-contact input device has been proposed that includes a non-contact detection unit that detects an input operation simply by making the detection unit of the non-contact detection unit transparent and simply bringing an operating body close to the case.
In a conventionally known non-contact input device using a capacitance detection method, a transparent holding plate is mounted on a unit configured as a display unit and is arranged on the back surface of the transparent holding plate, using LEDs that are self-luminous elements. The transparent electrode connected to the electrostatic capacitance detection circuit by the lead pattern monitors the change in electrostatic capacitance between the transparent electrode and its surroundings.
このように構成された非接触入力装置は、操作体である手が透明電極に接近していない待機時には、透明電極の周囲に接地電極がなく、透明電極に接続する静電容量検出回路で測定される静電容量は極めて小さい値となっている。この状態では、スイッチとしてはＯＦＦの状態となっている。 The non-contact input device configured in this way is measured by a capacitance detection circuit connected to the transparent electrode when there is no ground electrode around the transparent electrode during standby when the operating hand is not approaching the transparent electrode. The capacitance that is applied is extremely small. In this state, the switch is in an OFF state.
非接触入力装置へ入力操作を行う場合には、手を透明保持板上に接近させる。
手は、人体を介して接地電位に接続する一方の電極とみなされるので、透明電極と手の間でコンデンサが形成されるので、透明電極に手が接近することに伴って静電容量は増大し、静電容量検出回路で検出される静電容量が所定値を超えると、非接触入力装置への入力操作となりスイッチがＯＮの状態となる。
ここで特許文献１においては、スイッチが一つであり１種類のＯＮ／ＯＦＦ入力しか行うことが出来ないのに対して、特許文献２では複数の透明電極として８個または９個の透明電極を配置することで、入力操作位置や入力操作位置の変化による入力操作方向の検出等の多機能化を図っている。
Since the hand is regarded as one electrode connected to the ground potential via the human body, a capacitor is formed between the transparent electrode and the hand, so that the capacitance increases as the hand approaches the transparent electrode. When the capacitance detected by the capacitance detection circuit exceeds a predetermined value, an input operation is performed to the non-contact input device, and the switch is turned on.
Here, in Patent Document 1, there is one switch and only one type of ON / OFF input can be performed, whereas in Patent Document 2, eight or nine transparent electrodes are used as a plurality of transparent electrodes. By arranging, the multi-functionalization such as the detection of the input operation direction due to the input operation position and the change of the input operation position is achieved.
しかしながら、特許文献１の非接触入力装置は、一つの透明電極の静電容量の変化から入力操作を検出するので、入力操作の有無が検出できるだけであり、特許文献２では、入力操作位置や入力操作位置の変化による入力操作方向の検出の為に独立した多くの透明電極が必要となる。 However, since the non-contact input device of Patent Document 1 detects an input operation from a change in capacitance of one transparent electrode, it can only detect the presence or absence of the input operation. Many independent transparent electrodes are required to detect the input operation direction by changing the operation position.
一般に手によるスイッチ入力を、非接触で行う場合の異なる入力操作を検出する静電容量検出方式においては、複数の静電容量検出電極を基板上に配置し、各静電容量検出電極の静電容量の変化から入力操作を検出しているが、複数の静電容量検出電極を基板上に配置する場合には、前記した静電容量検出電極から静電容量検出回路へ引き出される引き出し線が、隣接する静電容量検出電極や操作体が接近する。このことによって発生する静電容量が、入力位置の誤差とならないように、静電容量検出電極からの引き出し線をスルーホールを介して基板背面側へ引き出している。しかしながら、スルーホールが形成された基板は通常の量産品では透明な品種がなく、複数の電極からなる透明な静電容量検出電極を、スルーホール無しで配置する場合には引き出し線の配置が困難となり、配置出来たとしても、引き出し線が占有する面積が広くなり小型化に対して不利なものとなっていた。 In general, in a capacitance detection method for detecting a different input operation when a switch input by hand is performed in a non-contact manner, a plurality of capacitance detection electrodes are arranged on a substrate, and the electrostatic capacitance of each capacitance detection electrode is detected. Although the input operation is detected from the change in capacitance, when a plurality of capacitance detection electrodes are arranged on the substrate, the lead lines drawn from the capacitance detection electrodes to the capacitance detection circuit are as follows: Adjacent capacitance detection electrodes and operating bodies approach. In order that the capacitance generated by this does not cause an error in the input position, a lead line from the capacitance detection electrode is drawn out to the back side of the substrate through the through hole. However, there is no transparent variety of substrates with through-holes in normal mass-produced products, and it is difficult to place the lead lines when arranging transparent capacitance detection electrodes consisting of multiple electrodes without through-holes Thus, even if it can be arranged, the area occupied by the lead lines becomes large, which is disadvantageous for miniaturization.
本発明は、上記した従来の問題点を考慮してなされたものであり、透明電極２個を隣接配置し、電極へ操作体を接近させ、入力操作を行う場合に、単純にスイッチ２個を使用した入力では２種類の入力しか出来なかったが、あらかじめ手の動きに関するパターンを記憶装置に記憶させておき、電極上で操作体を上下左右に移動、接近させ、入力操作を行う際の時間経過におけるＯＮ／ＯＦＦ出力のパターンを認識するし、あらかじめ手の動きに関するパターンと比較することにより、多くの入力操作を可能とする非接触入力装置を提供することを目的とする。 The present invention has been made in consideration of the above-described conventional problems. When two transparent electrodes are arranged adjacent to each other, an operating body is brought close to the electrodes, and an input operation is performed, two switches are simply provided. Although only two types of input were possible with the input used, the time required to perform input operations by storing patterns related to hand movements in advance in the storage device and moving and moving the operating body up and down and left and right on the electrodes. It is an object of the present invention to provide a non-contact input device that enables many input operations by recognizing an ON / OFF output pattern in the course and comparing it with a pattern relating to hand movement in advance.
前述の目的を達成するため、入力する手の動きに応じて複数種の信号を出力する非接触入力装置であって、出力信号の種類数未満である複数個の静電容量スイッチを絶縁シート上に隣接配置し、前記複数個の静電容量スイッチに接続され、静電容量スイッチの感度調整を行う静電容量タッチセンサを設け、静電容量スイッチのＯＮ/ＯＦＦを検出する静電容量検出部を備え、更に、いずれかの静電容量スイッチがＯＮになった後で、全ての静電容量スイッチがＯＦＦになる迄の間で、いずれかの静電容量スイッチがＯＮ又はＯＦＦに変化する迄の全ての時間を測定するタイマを備え、該タイマで計測した時間と前記複数個の静電容量スイッチのＯＮ/ＯＦＦの順番を、手の動き情報として記録するスイッチ操作判定部を備えると共に、前記非接触入力装置上で操作者が入力動作をしたときに、取得した前記手の動き情報を、予め登録しておいた手の動き情報と比較し、両情報が一致する場合には、予め登録しておいた手の動き情報に対応した信号を外部装置に出力することを特徴とする非接触入力装置。 In order to achieve the above-described object, a non-contact input device that outputs a plurality of types of signals in accordance with the movement of an input hand, wherein a plurality of capacitance switches that are less than the number of types of output signals are provided on an insulating sheet. A capacitance detection unit that is disposed adjacent to the plurality of capacitance switches, is connected to the plurality of capacitance switches, and is provided with a capacitance touch sensor that adjusts the sensitivity of the capacitance switches, and detects ON / OFF of the capacitance switches. Furthermore, after any capacitance switch is turned ON, until all capacitance switches are turned OFF, until any capacitance switch is turned ON or OFF Including a timer for measuring all the times of the above, a switch operation determination unit for recording the time measured by the timer and the order of ON / OFF of the plurality of capacitance switches as hand movement information, Non-contact When the operator performs an input operation on the input device, the obtained hand movement information is compared with the hand movement information registered in advance. A non-contact input device that outputs a signal corresponding to movement information of a hand to an external device.
本発明の非接触入力装置によれば、少ないスイッチ数から、数多くの信号を外部装置に出力することができ、例えば２個の透明電極を配置するだけで多入力が行えるので、電極の引き出し線の設計等が簡単となり多数の電極を用いた場合の電気的干渉などによる誤作動も低減でき、また電極の配置面積も小さく出来るので本非接触入力装置を搭載する機器がシンプルなデザインとすることが可能となり、入力操作によって多種類の入力を行う事が可能となる。 According to the non-contact input device of the present invention, a large number of signals can be output to an external device from a small number of switches. For example, multiple inputs can be performed simply by arranging two transparent electrodes. The design of the non-contact input device should be simple because the design of the device can be simplified and malfunctions caused by electrical interference when using a large number of electrodes can be reduced. Thus, various types of input can be performed by an input operation.

以下、添付の図面を参照して、本発明の実施例を説明する。
まず、図１は本実施形態のタッチセンサスイッチ装置の基本構成を説明するためのブロック図である。図１に示すように、透明絶縁シート３上に隣接して配置される透明電極スイッチ１と、透明電極スイッチ２があり、引き出しパターン４と５により、静電容量検出タッチセンサ部６へ接続されている。静電容量検出タッチセンサ部６は、透明電極スイッチ１、２上で、操作者の手が浮上した状態でスイッチがＯＮとなるように感度調整を行う。これによりスイッチ１及びスイッチ２上で手をかざすことにより、透明電極スイッチ１及び透明電極スイッチ２のＯＮ／ＯＦＦ状態を、スイッチ操作判定部９へ出力する。スイッチ操作判定部９には、タイマ１０も接続されており、静電容量検出タッチセンサ部６から透明電極スイッチ１または、透明電極スイッチ２のＯＮ状態が出力されてから、透明電極スイッチ１と透明電極スイッチ２が共に、ＯＦＦの状態となるまでのさらなるＯＮ／ＯＦＦ変化毎の時間経過をタイマ１０にて計測して、スイッチ操作判定部９内に記録する。
前記したタイマ１０は、入力を行う操作者の手の動きの時間を、スイッチ操作判定部９から検出出来れば、任意なもので良いが、例えばｍｓｅｃ単位での計測が可能なものを設定する。
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
First, FIG. 1 is a block diagram for explaining the basic configuration of the touch sensor switch device of the present embodiment. As shown in FIG. 1, there are a transparent electrode switch 1 and a transparent electrode switch 2 which are disposed adjacent to each other on a transparent insulating sheet 3, and are connected to a capacitance detection touch sensor unit 6 by lead patterns 4 and 5. ing. The electrostatic capacitance detection touch sensor unit 6 performs sensitivity adjustment on the transparent electrode switches 1 and 2 so that the switch is turned on with the operator's hand floating. As a result, the ON / OFF state of the transparent electrode switch 1 and the transparent electrode switch 2 is output to the switch operation determination unit 9 by holding the hand over the switch 1 and the switch 2. A timer 10 is also connected to the switch operation determination unit 9, and the transparent electrode switch 1 and the transparent electrode switch 2 are transparent after the capacitance detection touch sensor unit 6 outputs the ON state of the transparent electrode switch 1 or the transparent electrode switch 2. Both the electrode switches 2 are measured by the timer 10 for each further ON / OFF change until the electrode switches 2 are turned off and recorded in the switch operation determination unit 9.
The timer 10 may be any timer as long as the movement time of the operator's hand performing the input can be detected from the switch operation determination unit 9. For example, a timer that can measure in units of msec is set.
ここで図４のスイッチのＯＮ／ＯＦＦのタイミングに対して、時間計測をした結果、以降で説明するｔ１、ｔ２、ｔ３を表す模式図であるチャートと合わせて説明する。
スイッチ操作判定部９が記録するデータは、タッチセンサ部６から出力される透明電極スイッチ１または透明電極スイッチ２のＯＮになった状態から、タイマ１０で計測を開始し、２個のスイッチの状態が変化するたびに、その時間間隔を記録する。
以降両方のスイッチが、ＯＦＦとなるまで記録を続ける。この時、最初にスイッチＯＮとなった後に、もう片方のスイッチがＯＮとなる場合に、その経過時間をスイッチのＯＮからＯＮまでの時間ｔ１として記録し、当然２個のスイッチがＯＮとなれば、それぞれがＯＦＦとなるので、最初のＯＦＦまでの経過時間をｔ２、全てＯＦＦとなるまでの経過時間をｔ３として記録する事になる。 ここで、ｔ１、ｔ２、ｔ３の計測時間は手の動きの速度により計測毎に違った値となる。
Here, the result of time measurement with respect to the ON / OFF timing of the switch in FIG. 4 will be described together with a chart which is a schematic diagram showing t1, t2, and t3 described below.
The data recorded by the switch operation determination unit 9 is measured by the timer 10 from the state in which the transparent electrode switch 1 or the transparent electrode switch 2 output from the touch sensor unit 6 is turned on, and the states of the two switches Whenever changes, record the time interval.
Thereafter, recording is continued until both switches are turned off. At this time, when the other switch is turned on after the switch is first turned on, the elapsed time is recorded as the time t1 from the ON of the switch to the ON, and naturally if the two switches are turned on. Since each is OFF, the elapsed time until the first OFF is recorded as t2, and the elapsed time until all are OFF is recorded as t3. Here, the measurement times of t1, t2, and t3 are different values for each measurement depending on the speed of hand movement.
以下、スイッチ操作判定部９で記録されたｔ１、ｔ２、ｔ３より、図４で示すような手の動きから多種のパターンを定義し事前登録したスイッチ操作判定部９が、蓄積したパターンと一致するかを判断することで手の動きを多種の入力操作としてあつかう場合の説明を行う。
まずｔ１のみ記録された場合には、図４においてＰ１またはＰ２のパターンであることが判定でき、透明電極スイッチ１がＯＮならＰ１、透明電極スイッチ２がＯＮならＰ２と断定出来る。
次に２個のスイッチ（透明電極スイッチ１、透明電極スイッチ２）がＯＮなった場合は、図４に示す２個のスイッチのＯＮとＯＮの経過時間ｔ１、２個ともＯＮの経過時間ｔ２、２個のスイッチのＯＦＦとＯＦＦの経過時間ｔ３の時間経過がスイッチ操作判定部９に記録されることになる。
Hereinafter, from t1, t2, and t3 recorded by the switch operation determination unit 9, the switch operation determination unit 9 in which various patterns are defined from hand movements as shown in FIG. 4 and registered in advance matches the accumulated pattern. An explanation will be given of handling hand movements as various input operations.
First, when only t1 is recorded, it can be determined that the pattern is P1 or P2 in FIG. 4, and can be determined as P1 when the transparent electrode switch 1 is ON, and P2 when the transparent electrode switch 2 is ON.
Next, when two switches (transparent electrode switch 1 and transparent electrode switch 2) are turned on, the two switches shown in FIG. The two switches OFF and the elapsed time t3 of OFF are recorded in the switch operation determination unit 9.
ここで手の移動速度の設定や計測誤差も考慮して、例えばｔ１、ｔ３の計測時間が１ｍｓｅｃ以下の場合は、同時にＯＮ、ＯＦＦとなるように、静電容量検出タッチスイッチ６を設定し、スイッチ操作判定部９で判断させるようにする。従ってｔ１＜２ｍｓｅｃかつｔ３＜２ｍｓｅｃの場合は、図４のＰ１０が同時にＯＮで同時にＯＦＦであるから一致する事がスイッチ操作判定部９で判断できる。さらにｔ１＜２ｍｓｅｃかつｔ３＞１ｍｓｅｃの場合は図４のＰ９、Ｐ１１が同時にＯＮで２個のＯＦＦがずれた時間であるとスイッチ操作判定部９で判断でき、スイッチ２が先にＯＦＦならＰ９、スイッチ１が先にＯＦＦならＰ１１とスイッチ操作判定部９で断定できる。さらにｔ１＞１ｍｓｅｃかつｔ３＜２ｍｓｅｃの場合はＰ４、Ｐ７とスイッチ操作判定部９で判断でき、スイッチ１が先にＯＮならＰ４、スイッチ２が先にＯＮならＰ７とスイッチ操作判定部９で断定出来る。さらにｔ１＞１ｍｓｅｃかつｔ３＞１ｍｓｅｃの場合はＰ３、Ｐ５、Ｐ６、Ｐ８とスイッチ操作判定部９で判断でき（２個のスイッチがずれた時間で順番にＯＮ、順番にＯＦＦであり、スイッチ１が先にＯＮ・ＯＦＦならＰ３、スイッチ２が先にＯＮ・ＯＦＦならＰ８、スイッチ１が先にＯＮしスイッチ２が先にＯＦＦならＰ５、スイッチ２が先にＯＮしスイッチ１が先にＯＦＦならＰ６とスイッチ操作判定部９で断定できる。
以上スイッチ１とスイッチ２のどちらが先にＯＮ、ＯＦＦしたかと時間経過の判断で合計１１種類の入力が可能となる。
Here, considering the setting of the moving speed of the hand and the measurement error, for example, when the measurement time of t1 and t3 is 1 msec or less, the capacitance detection touch switch 6 is set so that it is turned on and off at the same time. The switch operation determination unit 9 makes a determination. Therefore, when t1 <2 msec and t3 <2 msec, the switch operation determination unit 9 can determine that P10 in FIG. Further, in the case of t1 <2 msec and t3> 1 msec, the switch operation determination unit 9 can determine that P9 and P11 in FIG. 4 are simultaneously ON and the two OFFs are shifted, and if switch 2 is OFF first, P9, If switch 1 is OFF first, it can be determined by P11 and switch operation determination unit 9. Further, when t1> 1 msec and t3 <2 msec, it can be determined by P4, P7 and the switch operation determination unit 9, and can be determined by P4 if the switch 1 is ON first, and P7 and the switch operation determination unit 9 if switch 2 is ON first. . Further, when t1> 1 msec and t3> 1 msec, it can be determined by the switch operation determination unit 9 with P3, P5, P6, P8 (the two switches are turned on in turn and turned off in turn, and the switch 1 is turned off. P3 if switch ON / OFF first, P8 if switch 2 is ON / OFF first, P5 if switch 1 is ON first and switch 2 is OFF first, P5 if switch 2 is ON first and switch 1 is OFF first, P6 Can be determined by the switch operation determination unit 9.
As described above, a total of 11 types of inputs can be made by determining which switch 1 or switch 2 is turned ON or OFF first and determining the passage of time.
前記１１種類のパターンに対してＰ１、Ｐ２以外ではさらにｔ２の時間経過で例えば操作者の手がスイッチ上で１秒（１０００ｍｓｅｃ）以上停止させた場合を停止したものと定義した場合で判断すれば、ｔ２が１０００ｍｓｅｃ以下か以上の判断で停止の有無の組み合わせが増え、Ｐ１、Ｐ２においてはｔ１が１０００ｍｓｅｃ以下か以上の判断で停止の有無の組み合わせが増える事で１１種類のパターンが倍のパターンとなるので、あわせて２２種類の入力が可能となる。そして２２種類のどれか一つと判断出来たスイッチ操作判定部９は２２種類のＯＮ信号の内の１つとしてＯＮ信号１１を外部装置１２へ出力する事で２２個のスイッチが実装されたものと同等になり多入力が可能となる。 For the 11 types of patterns, except for P1 and P2, if the operator's hand is stopped on the switch for more than 1 second (1000 msec) after the elapse of time t2, for example, it is determined that it is stopped. , The combination of presence / absence of stoppage is increased when t2 is 1000 msec or less, and the combination of presence / absence of stoppage is increased by determining whether t1 is 1000 msec or less at P1 and P2. Therefore, a total of 22 types of input are possible. Then, the switch operation determination unit 9 that has been determined to be one of 22 types outputs 22 ON switches as one of 22 types of ON signals, and 22 switches are mounted. It becomes equivalent and multiple inputs are possible.
