本発明は、一空間に実像を形成し、この実像を見ながら特定の位置を入力できる空中タッチパネルに関する。
The present invention relates to an aerial touch panel capable of forming a real image in one space and inputting a specific position while viewing the real image.
ディスプレイ（表示器）に画像を表示し、画像の特定の場所を指で押すと感圧センサーなどで押圧部分のＸＹ座標が検知され、この入力信号によって次の動作を行うことは従来から知られている（例えば、特許文献１参照）。
It is conventionally known that an image is displayed on a display (display device), and when a specific place on the image is pressed with a finger, the XY coordinates of the pressed portion are detected by a pressure sensor or the like, and the next operation is performed by this input signal. (For example, refer to Patent Document 1).
また、特許文献２に記載されているように、ディスプレイの直上に発光素子と受光素子をＸＹ軸に沿って多数平行に並べてマトリックスを形成し、指やペン等の障害物でディスプレイの表面をタッチした場合は、その障害物がマトリックスを横切ることで、ディスプレイに当接した位置を検知していた。
Also, as described in Patent Document 2, a matrix is formed by arranging a number of light emitting elements and light receiving elements in parallel along the XY axes directly above the display, and the surface of the display is touched with an obstacle such as a finger or a pen. In this case, the position where the obstacle is in contact with the display is detected as the obstacle crosses the matrix.

The image forming means 12 that outputs to the space and forms the image B, and the optical position input means 13 arranged in one space where the image B is displayed are included. These will be described in detail below. Note that the image B includes a case where at least a main part is the same as the image A.
図１～図３に示すように、本発明の一実施例に係る空中タッチパネル１０は、発光性を有する画像Ａを表示する表示器（ディスプレイ）１１と、表示器１１の画像Ａを入力し一空間に出力して画像Ｂを結像する結像手段１２と、画像Ｂが表示される一空間に配置された光学式の位置入力手段１３とを有する。以下、これらについて詳しく説明する。なお、画像Ｂは画像Ａと少なくとも要部が同一である場合も含む。 Next, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIGS. 1 to 3, an
表示器１１は通常の液晶ディスプレイ、ブラウン管ディスプレイ、プラズマディスプレイ、有機ＥＬディスプレイ等の平面ディスプレイが使用できるが、例えば、立体物であってもよいし、自体は発光せず、他の光の反射光によって自体が発光しているように見えるものも含む。更に画像Ａは平面的であってもよいし、立体的（立体像）であってもよい。

However, for example, it may be a three-dimensional object, or it does not emit light and reflects other light. Including those that appear to emit light. Furthermore, the image A may be planar or a stereoscopic (stereoscopic image).
結像手段１２は、図３（Ａ）、（Ｂ）に示すように、透明平板１５、１６の内部にそれぞれ多数の第１、第２の帯状光反射部１７、１８を平行かつ一定間隔で並べた第１、第２の光制御パネル１９、２０が、第１、第２の帯状光反射部１７、１８を平面視して（矢視Ｐから見て）交差状態（例えば、直交状態）にして当接又は近接配置されている。
As shown in FIGS. 3 (A) and 3 (B), the image forming means 12 has a large number of first and second strip-shaped light reflecting portions 17 and 18 arranged in parallel and at regular intervals inside transparent plates 15 and 16, respectively. The arranged first and second light control panels 19 and 20 are in an intersecting state (for example, an orthogonal state) when the first and second strip-shaped light reflecting portions 17 and 18 are viewed in plan (viewed from an arrow P). In this manner, they are in contact or in close proximity.
これによって、一つの空間にある表示器１１のα、βから出た光は、第１の帯状光反射部１７によって鏡面反射し、その上の第２の帯状光反射部１８によって２回目の鏡面反射をし、α’、β’が他の空間に結像する。この結像する位置に光学式の位置入力手段１３が設けられている。
As a result, the light emitted from α and β of the display 11 in one space is specularly reflected by the first band-shaped light reflecting portion 17 and is reflected by the second band-shaped light reflecting portion 18 on the second mirror surface. Reflected and α ′ and β ′ are imaged in another space. An optical position input means 13 is provided at the position where the image is formed.
この光学式の位置入力手段１３は図２に示すように四角形の縦部材２１、２２と横部材２３、２４とを有する枠体２５を有し、対向配置される縦部材２１、２２には投光素子２６と受光素子２７の対が所定間隔で多数配置され、対向配置される横部材２３、２４には投光素子２８と受光素子２９の対が所定間隔で多数配置されている。

A
従って、この空中タッチパネル１０を使用する場合は、表示器１１に特定の画像Ａを表示させ、この表示された画像Ａを枠体２５内に画像Ｂとして結像させる。この画像Ｂは実像であるので、枠体２５内の空間部に結像される。従って、この画像Ｂの上に指３２を置くと、投光素子２６、２８から受光素子２７、２９に向かう光を横切ることになり、その位置が位置入力手段１３によって検知される。
なお、指等によって入力すると、複数本の光線を横切ることになるが、その場合の中央の光線を採用すると、入力位置のＸＹ座標が点として決まる。 Therefore, when using theaerial touch panel 10, a specific image A is displayed on the display 11, and the displayed image A is formed as an image B in the frame 25. Since this image B is a real image, it is formed in a space part in the frame 25. Therefore, when the finger 32 is placed on the image B, the light traveling from the light projecting elements 26 and 28 toward the light receiving elements 27 and 29 is crossed, and the position is detected by the position input means 13.
In addition, if it inputs with a finger | toe etc., it will cross a some light ray, but if the center light ray in that case is employ | adopted, the XY coordinate of an input position will be decided as a point.
なお、指等によって入力すると、複数本の光線を横切ることになるが、その場合の中央の光線を採用すると、入力位置のＸＹ座標が点として決まる。 Therefore, when using the
In addition, if it inputs with a finger | toe etc., it will cross a some light ray, but if the center light ray in that case is employ | adopted, the XY coordinate of an input position will be decided as a point.
この場合、枠体２５の内側は空間部であるので、枠体２５の背面（背部）に透明板又は半透明材からなる保護部材３１（図１参照）を設けることもできる。これによって、指３２で押す位置が明確となる。なお、この保護部材３１があると指３２のタッチによって汚れるので、省略するのが最も好ましいが、保護部材３１を枠体２５に近接して設ける場合は格子面３０との間に隙間を設けるのがよい。
In this case, since the inside of the frame 25 is a space portion, a protective member 31 (see FIG. 1) made of a transparent plate or a translucent material can be provided on the back surface (back portion) of the frame 25. As a result, the position pressed by the finger 32 becomes clear. It is most preferable to omit the protective member 31 because it is soiled by the touch of the finger 32. However, when the protective member 31 is provided close to the frame body 25, a gap is provided between the protective member 31 and the lattice surface 30. Is good.
なお、図４に示す本発明の他の実施例に係る空中タッチパネルのように、枠体２５内に立体像３４を形成することもできる。図４には押しボタンスイッチ（例えば、キーボード）等の立体像３４を形成し、その表面に格子面３０を配置すると、押しボタンスイッチの画像に触れることによって、その位置を検知し、入力信号を得ることが可能となる。特に、キーボード等の立体像の場合は、そのキーをオンにしたことを示すため、音又は光（例えば、当接したキーが光る）を発するようにするのがよい。
In addition, the three-dimensional image 34 can also be formed in the frame 25 like the aerial touch panel which concerns on the other Example of this invention shown in FIG. In FIG. 4, when a three-dimensional image 34 such as a push button switch (for example, a keyboard) is formed and a lattice plane 30 is arranged on the surface, the position of the push button switch is detected by touching the image of the push button switch. Can be obtained. In particular, in the case of a three-dimensional image such as a keyboard, it is preferable to emit a sound or light (for example, the touched key shines) to indicate that the key is turned on.
前記実施例においては、結像手段１２として、第１、第２の光制御パネル１９、２０を組み合わせたものを用いて説明したが、枠体２５内に実像を形成するものであれば、他の手段（例えば、直交する反射面を多数有する２面リフレクター、レンズ等）を用いることもできる。
In the above embodiment, the imaging means 12 has been described using a combination of the first and second light control panels 19 and 20, but any other means can be used as long as it forms a real image in the frame 25. (For example, a two-surface reflector having a large number of orthogonal reflecting surfaces, a lens, etc.) can also be used.
本発明は以上の実施例に限定されるものではなく、本発明の要旨を変更しない空中タッチパネルにも適用可能である。例えば、本発明においては、位置入力手段として、直交する赤外線等の光線の格子面を用いたが、１又は複数箇所にある投光部からの光線がスキャンするものであってもよい。また、位置入力手段として、複数のカメラを用いて指等の位置を画像処理によって検知するもの、例えば、リープモーションセンサー（「Ｌｅａｐ」商品名、Ｌｅａｐ Ｍｏｔｉｏｎ社製）であってもよい。
前記実施例においては、指を使って入力したが、タッチペン等の指示手段であってもよい。
更には、前記実施例においては、枠体の背面に保護部材を配置しているが、この保護部材の代わりに、この保護部材と共に、空中タッチパネルに触れる指等の触感を出すための機構（例えば、超音波等を使用して、空中タッチパネルに触れた指に接触感を与える）を設けることもできる。 The present invention is not limited to the above embodiments, and can be applied to an aerial touch panel that does not change the gist of the present invention. For example, in the present invention, the lattice plane of light beams such as orthogonal infrared rays is used as the position input means, but the light beams from the light projecting units at one or a plurality of locations may be scanned. The position input means may be a device that detects the position of a finger or the like by image processing using a plurality of cameras, for example, a leap motion sensor (“Leap” product name, manufactured by Leap Motion).
In the embodiment, the input is performed using a finger, but an instruction means such as a touch pen may be used.
Furthermore, in the said Example, although the protective member is arrange | positioned on the back surface of a frame, instead of this protective member, the mechanism (for example, a finger | toe etc. which touches an aerial touch panel with this protective member) In addition, using a ultrasonic wave or the like, a finger touching the aerial touch panel is given a touch feeling).
