First, a configuration of an electronic blackboard device as a display device according to an embodiment of the present invention will be described based on the drawings.
In this embodiment, an electronic blackboard device as a display device will be described as an example. However, the display device of the present invention is a portable terminal such as a portable or stationary personal computer, a cellular phone, or a PDA (Personal Digital Assistant). You may use for a display apparatus of a device, business information, and in-vehicle information, and you may use for operating devices, such as an electronic device and a navigation apparatus. In the present embodiment, scrolling an image means a process of moving an image displayed on the display surface and displaying a portion of the image that is not displayed on the display surface in accordance with the movement. To do.

FIG. 4 is a schematic diagram showing the map after the scroll process. FIG. 5 is a schematic diagram showing a line after drawing on a map.
　図１および図２において、表示装置としての電子黒板装置１は、学校での授業や会社での会議に使用され、表示面３１上における指示手段としての指Ｆの指示位置に応じて、表示面３１内に表示しきれない大きさの地図Ｍをスクロールさせたり、この地図Ｍ上に線Ｌ（図５参照）を描画する。
　ここで、本実施形態において、指示とは、表示面３１上に設けられたタッチパネル４０と、指Ｆとが接触している状態を意味する。また、指示手段として利用者の指Ｆに基づく処理を例示するが、ペンや棒状の部材などの表示面３１上を指示可能な指示手段が表示面３１を指示した際にも、指Ｆの場合と同様の処理をする。さらに、地図Ｍをスクロールさせたり地図Ｍ上に線Ｌを描画する場合を例示するが、地図Ｍ以外の画像であり表示面３１内に表示しきれない大きさのものが表示された場合にも、スクロールさせたり線Ｌを描画したりする。なお、指示手段としては、表示面３１に表示されるカーソルを移動させるマウスやポインタデバイス、あるいは、光学式のポインタなどを適用してもよい。 1 and 2, the electronic blackboard device 1 as a display device is used for a lesson at a school or a meeting at a company, and a display surface according to an instruction position of a finger F as an instruction means on the display surface 31. A map M having a size that cannot be displayed in the screen 31 is scrolled or a line L (see FIG. 5) is drawn on the map M.
Here, in the present embodiment, the instruction means a state where the touch panel 40 provided on the display surface 31 and the finger F are in contact with each other. Further, the processing based on the user's finger F is exemplified as the instruction means. However, when the instruction means capable of instructing on the display surface 31 such as a pen or a bar-shaped member instructs the display surface 31, The same processing is performed. Furthermore, although the case where the map M is scrolled or the line L is drawn on the map M is illustrated, an image other than the map M and a size that cannot be displayed in the display surface 31 is displayed. , Scroll or draw line L. Note that a mouse or pointer device for moving a cursor displayed on the display surface 31 or an optical pointer may be applied as the instruction means.
　また、電子黒板装置１は、一面から表示面３１が露出可能な略四角箱状の本体１０を備えており、表示面３１が略垂直になるように設置される。そして、本体１０には、記憶手段２０と、表示手段３０と、タッチパネル４０と、演算手段としての情報処理装置５０と、が設けられている。 Also, the electronic blackboard device 1 includes a substantially square box-shaped main body 10 from which the display surface 31 can be exposed, and is installed so that the display surface 31 is substantially vertical. The main body 10 is provided with a storage unit 20, a display unit 30, a touch panel 40, and an information processing device 50 as a calculation unit.
　記憶手段２０には、表示面３１に地図Ｍや各種テキストあるいは各種画像を表示させるための表示用データや、電子黒板装置１の動作に必要な各種情報が記憶されている。なお、記憶手段２０は、本体１０の図示しない端子に着脱可能な構成であってもよい。 The storage means 20 stores display data for displaying the map M, various texts or various images on the display surface 31, and various information necessary for the operation of the electronic blackboard device 1. The storage unit 20 may be configured to be detachable from a terminal (not shown) of the main body 10.
　表示手段３０の表示面３１には、記憶手段２０の表示用データに基づく地図Ｍなどが表示される。なお、表示手段３０としては、例えば液晶パネルや有機ＥＬ（Electro Luminescence）パネル、ＰＤＰ（Plasma Display Panel）、ＣＲＴ（Cathode-Ray Tube）、ＦＥＤ（Field Emission Display）、電気泳動ディスプレイパネルなどが例示できる。なお、専用のタッチパネル４０に対応する入力手段が必要となるが、表示手段として、プロジェクタのような投影式のものを適用してもよい。 On the display surface 31 of the display means 30, a map M based on the display data of the storage means 20 is displayed. Examples of the display means 30 include a liquid crystal panel, an organic EL (Electro Luminescence) panel, a PDP (Plasma Display Panel), a CRT (Cathode-Ray Tube), an FED (Field Emission Display), and an electrophoretic display panel. . Note that an input unit corresponding to the dedicated touch panel 40 is required, but a projection type display such as a projector may be applied as the display unit.
　タッチパネル４０は、表示手段３０の表示面３１を覆う状態で設けられ、利用者が接触可能な構成を有している。このタッチパネル４０は、表示面３１と略等しい形状に形成されており、指Ｆが接触した位置に関する接触信号を情報処理装置５０へ出力する。なお、タッチパネルの代わりに、表示面３１やホワイトボードなどに着脱可能な構成を有し、表示面３１が専用の指示手段または指などの指示手段により指示されたときに、これらの指示手段が表示面３１の指示位置に相当する位置に接触するのを検出し、あるいは表示面３１の指示位置に相当する位置から所定距離以内に接近したときに表示面３１に接触されたとみなす接触信号を出力する構成を適用してもよい。本明細書において指示手段が表示面を指示している状態とは、このように指示手段が表示面から所定距離以内に接近したときを含むものである。 The touch panel 40 is provided in a state of covering the display surface 31 of the display means 30 and has a configuration that can be contacted by the user. The touch panel 40 is formed in a shape substantially equal to the display surface 31, and outputs a contact signal regarding the position where the finger F is in contact to the information processing device 50. In addition, instead of the touch panel, the display surface 31 or the whiteboard has a configuration that can be attached and detached. When the display surface 31 is instructed by a dedicated instruction means or an instruction means such as a finger, these instruction means display A contact signal that detects contact with the display surface 31 is output when a contact with a position corresponding to the indicated position on the surface 31 is detected or when a position within a predetermined distance from the position corresponding to the indicated position on the display surface 31 is approached. A configuration may be applied. In this specification, the state in which the instruction means indicates the display surface includes the time when the instruction means approaches within a predetermined distance from the display surface.
　情報処理装置５０は、各種プログラムから構成された、画像表示制御手段５１と、処理選択領域設定手段５２と、選択領域区別手段５３と、指示軌跡認識手段５４と、処理実施手段５５と、を備えている。 The information processing apparatus 50 includes an image display control unit 51, a process selection area setting unit 52, a selection area discrimination unit 53, an instruction locus recognition unit 54, and a process execution unit 55, which are configured by various programs. ing.
　画像表示制御手段５１は、タッチパネル４０あるいは図示しない入力手段による入力操作に基づいて、所定の地図Ｍを表示させる。この地図Ｍの表示の際、地図Ｍの縮尺によっては、図２に示すように、表示面３１に地図Ｍ全体を表示できない場合がある。この場合、画像表示制御手段５１は、表示面３１に地図Ｍの一部のみを表示させる。また、画像表示制御手段５１は、表示用データに基づく各種テキストや各種画像を表示させる。 The image display control means 51 displays a predetermined map M based on an input operation by the touch panel 40 or an input means (not shown). When the map M is displayed, depending on the scale of the map M, the entire map M may not be displayed on the display surface 31 as shown in FIG. In this case, the image display control means 51 displays only a part of the map M on the display surface 31. Further, the image display control means 51 displays various texts and various images based on the display data.
　処理選択領域設定手段５２は、表示面３１を表示面３１の中央に位置する描画選択領域Ａ２と描画選択領域Ａ２の周辺に位置するスクロール選択領域Ａ１に区分する。具体的には、処理選択領域設定手段５２は、表示面３１の外縁を構成する四辺に沿って、図２および図３に示すように、四角枠状のスクロール選択領域Ａ１を設定する。このスクロール選択領域Ａ１は、四角枠を構成する各辺の幅寸法Ｎ１，Ｎ２，Ｎ３，Ｎ４が略同一に設定されている。さらに、処理選択領域設定手段５２は、表示面３１におけるスクロール選択領域Ａ１で囲まれる全領域を描画選択領域Ａ２として設定する。なお、スクロール選択領域Ａ１の四角枠状を構成する各辺の幅寸法Ｎ１～Ｎ４としては、当該領域に指Ｆを接触可能な寸法であることが好ましい。また、幅寸法Ｎ１～Ｎ４は、異なっていてもよい。なお、本明細書では、表示面３１の外縁というとき、外縁は表示面３１に含まれるものとする。 The process selection area setting means 52 divides the display surface 31 into a drawing selection area A2 located at the center of the display surface 31 and a scroll selection area A1 located around the drawing selection area A2. Specifically, the process selection area setting means 52 sets a rectangular frame-shaped scroll selection area A1 as shown in FIGS. 2 and 3 along the four sides constituting the outer edge of the display surface 31. In the scroll selection area A1, the width dimensions N1, N2, N3, and N4 of each side constituting the square frame are set to be substantially the same. Furthermore, the process selection area setting means 52 sets the entire area surrounded by the scroll selection area A1 on the display surface 31 as the drawing selection area A2. Note that the width dimensions N1 to N4 of each side constituting the rectangular frame shape of the scroll selection area A1 are preferably dimensions that allow the finger F to contact the area. Further, the width dimensions N1 to N4 may be different. In this specification, the outer edge of the display surface 31 is included in the display surface 31.
　選択領域区別手段５３は、図２および図３に示すように、スクロール選択領域Ａ１と略等しい四角枠状を有し、かつ、半透明な半透明画像Ｃ１を、スクロール選択領域Ａ１と重ねて表示させる。利用者は、この半透明な半透明画像Ｃ１を介して、地図Ｍのスクロール選択領域Ａ１に表示されている部分を視認することができる。つまり、選択領域区別手段５３は、半透明画像Ｃ１の表示により、スクロール選択領域Ａ１と描画選択領域Ａ２とを区別可能、かつ、スクロール選択領域Ａ１内に表示中の地図Ｍを認識可能な状態に、地図Ｍの表示形態を設定する。なお、半透明画像Ｃ１の透過率としては、３０％～６０％が好ましい。ただし、一般的に、半透明画像Ｃ１を介した地図Ｍの認識度は、個人により、また地図Ｍのスクロール選択領域Ａ１に表示されている部分の色により異なるため、スクロール選択領域は図示しない入力手段により半透明画像Ｃ１の透過率を変更可能な構成とすることが好ましい。また、スクロール選択領域Ａ１に表示されている部分の色に応じて半透明画像Ｃ１の透過率を自動的に変化させることが好ましい。 As shown in FIGS. 2 and 3, the selection area discriminating means 53 has a rectangular frame shape substantially equal to the scroll selection area A1, and displays a semitransparent semitransparent image C1 overlapping the scroll selection area A1. Let The user can visually recognize the portion displayed in the scroll selection area A1 of the map M through the semitransparent semitransparent image C1. That is, the selection area discriminating means 53 can distinguish between the scroll selection area A1 and the drawing selection area A2 by displaying the translucent image C1, and can recognize the map M being displayed in the scroll selection area A1. The display form of the map M is set. Note that the transmittance of the translucent image C1 is preferably 30% to 60%. However, since the recognition degree of the map M via the semi-transparent image C1 generally differs depending on the individual and the color of the portion displayed in the scroll selection area A1 of the map M, the scroll selection area is not illustrated. It is preferable that the transmissivity of the translucent image C1 can be changed by means. Further, it is preferable to automatically change the transmissivity of the translucent image C1 according to the color of the portion displayed in the scroll selection area A1.
　指示軌跡認識手段５４は、図２に示すように、利用者の指Ｆが表示面３１を指示した指示軌跡Ｔａ（ａは整数）、すなわちタッチパネル４０に接触した指示軌跡Ｔａを認識する。具体的には、指示軌跡認識手段５４は、タッチパネル４０からの接触信号に基づいて指Ｆの最初の接触位置（表示面３１上の最初の指示位置）を指示開始位置Ｐｂ（ｂは整数）として特定する。さらに、この指示状態（指Ｆがタッチパネル４０に接触した状態）を維持しつつ、指Ｆが移動したことを認識すると、指示開始位置Ｐｂの認識から所定時間経過した時点、または、指Ｆの移動開始から所定時間経過した時点における位置を軌跡確定位置として特定して、指示開始位置Ｐｂから軌跡確定位置までの指示軌跡Ｔａを認識する。なお、指示軌跡認識手段５４は、指示開始位置Ｐｂを特定した後に、指Ｆが移動せずにタッチパネル４０から離れたことを認識すると、指示軌跡Ｔａを特定しない。 As shown in FIG. 2, the instruction locus recognition means 54 recognizes an instruction locus Ta (a is an integer) that the user's finger F points to the display surface 31, that is, an instruction locus Ta that touches the touch panel 40. Specifically, the instruction locus recognition unit 54 sets the first contact position (first instruction position on the display surface 31) of the finger F as the instruction start position Pb (b is an integer) based on the contact signal from the touch panel 40. Identify. Further, when it is recognized that the finger F has moved while maintaining this instruction state (a state where the finger F is in contact with the touch panel 40), or when the predetermined time has elapsed from the recognition of the instruction start position Pb, or the movement of the finger F The position at the time when a predetermined time has elapsed from the start is specified as the locus determination position, and the instruction locus Ta from the instruction start position Pb to the locus determination position is recognized. The instruction locus recognition means 54 does not specify the instruction locus Ta when it recognizes that the finger F has left the touch panel 40 without moving after specifying the instruction start position Pb.
　処理実施手段５５は、指Ｆによる指示位置に応じた処理をする。具体的には、処理実施手段５５は、指示軌跡認識手段５４で特定された指示開始位置Ｐｂがスクロール選択領域Ａ１内であり、かつ、指示軌跡Ｔａが認識されると、この指示軌跡Ｔａの形状に対応させて、地図Ｍをスクロールする。例えば、図２に示すように、スクロール選択領域Ａ１内の指示開始位置Ｐ１１が指示された後に、指Ｆが描画選択領域Ａ２内の軌跡確定位置Ｑ１１まで移動して、左斜め下方向へ延びる指示軌跡Ｔ１１が特定された場合、図４に示すように、左斜め下方向に向けて直線状に指示軌跡Ｔ１１の長さに対応する量だけ、地図Ｍをスクロールする。また、いずれもスクロール選択領域Ａ１内の指示開始位置Ｐ１１と軌跡確定位置Ｑ１２を結び、左真横方向へ延びる指示軌跡Ｔ１２が特定された場合、ここでは図示しないが、左真横方向に向けて地図Ｍをスクロールする。
　つまり、処理実施手段５５は、指示開始位置Ｐｂがスクロール選択領域Ａ１内の場合、指示軌跡Ｔａの位置にかかわらず、指示軌跡Ｔ１１の方向と長さに対応して地図Ｍをスクロールする。このとき、指示軌跡Ｔ１１と同じの方向に、指示軌跡Ｔ１１と同じ長さだけ地図Ｍをスクロールするのが、利用者には直感的に分かりやすく、操作性がいい。また指示軌跡Ｔ１１が直線でなく蛇行する線のときは、その線の形状と同じ蛇行する線に従って地図Ｍをスクロールするのが、利用者には直感的に分かりやすく、操作性がいい。 The processing execution unit 55 performs processing according to the position indicated by the finger F. Specifically, when the instruction start position Pb specified by the instruction trajectory recognition means 54 is within the scroll selection area A1 and the instruction trajectory Ta is recognized, the processing execution unit 55 determines the shape of the instruction trajectory Ta. The map M is scrolled in correspondence with. For example, as shown in FIG. 2, after the instruction start position P11 in the scroll selection area A1 is instructed, the finger F moves to the locus confirmation position Q11 in the drawing selection area A2, and extends to the left diagonally downward direction. When the trajectory T11 is specified, the map M is scrolled by an amount corresponding to the length of the instruction trajectory T11 in a straight line toward the lower left as shown in FIG. In any case, when the instruction locus T12 that connects the instruction start position P11 and the locus determination position Q12 in the scroll selection area A1 and extends to the left lateral direction is specified, although not shown here, the map M is directed toward the left lateral direction. Scroll.
That is, when the instruction start position Pb is within the scroll selection area A1, the processing execution unit 55 scrolls the map M in accordance with the direction and length of the instruction locus T11 regardless of the position of the instruction locus Ta. At this time, scrolling the map M in the same direction as the instruction locus T11 by the same length as the instruction locus T11 is easy for the user to understand intuitively and has good operability. When the instruction locus T11 is not a straight line but a meandering line, scrolling the map M according to the meandering line that is the same as the shape of the line is intuitive and easy to understand for the user.
　また、処理実施手段５５は、指示開始位置Ｐｂが描画選択領域Ａ２であり、かつ、指示軌跡Ｔａが認識されると、この指示軌跡Ｔａの形状と同じ線Ｌを地図Ｍに重ねて描画する。例えば、図２に示すように、描画選択領域Ａ２内の指示開始位置Ｐ２１が指示された後に、指Ｆがスクロール選択領域Ａ１内の軌跡確定位置Ｑ２１まで移動して、左斜め上方向へ湾曲しながら延びる指示軌跡Ｔ２１が特定された場合、図５に示すように、指示軌跡Ｔ２１と同じ形状の線Ｌを描画する。また、いずれも描画選択領域Ａ２内の指示開始位置Ｐ２１と軌跡確定位置Ｑ２２を結び、右斜め下方向へ湾曲しながら延びる指示軌跡Ｔ２２が特定された場合、ここでは図示しないが、指示軌跡Ｔ２２と同じ形状の線を描画する。
　つまり、処理実施手段５５は、指示開始位置Ｐｂが描画選択領域Ａ２内の場合、指示軌跡Ｔａの位置にかかわらず、指示軌跡Ｔａと同じ形状の線Ｌを地図Ｍ上に描画する。このように、指示開始位置Ｐｂが描画選択領域Ａ２内であり、かつ、指示軌跡Ｔａの一部がスクロール選択領域Ａ１に重なっている場合でも、指示軌跡Ｔａに沿った線Ｌを描画選択領域Ａ２とスクロール選択領域Ａ１とに描画することで、表示面３１の全領域に線Ｌを描画することができ、電子黒板装置１の利便性が向上する。 Further, when the instruction start position Pb is the drawing selection area A2 and the instruction locus Ta is recognized, the processing execution unit 55 draws the same line L as the shape of the instruction locus Ta on the map M. For example, as shown in FIG. 2, after the instruction start position P21 in the drawing selection area A2 is instructed, the finger F moves to the locus determination position Q21 in the scroll selection area A1 and bends diagonally upward to the left. When the instruction locus T21 extending while being specified is specified, a line L having the same shape as the instruction locus T21 is drawn as shown in FIG. In both cases, when the instruction locus T22 that connects the instruction start position P21 and the locus determination position Q22 in the drawing selection area A2 and extends while being curved diagonally downward to the right is specified, although not shown here, the instruction locus T22 Draw lines of the same shape.
That is, when the instruction start position Pb is within the drawing selection area A2, the processing execution unit 55 draws a line L having the same shape as the instruction locus Ta on the map M regardless of the position of the instruction locus Ta. Thus, even when the instruction start position Pb is in the drawing selection area A2 and a part of the instruction locus Ta overlaps the scroll selection area A1, the line L along the instruction locus Ta is drawn in the drawing selection area A2. By drawing in the scroll selection area A1, the line L can be drawn in the entire area of the display surface 31, and the convenience of the electronic blackboard device 1 is improved.
［電子黒板装置の動作］
　次に、電子黒板装置１の動作について説明する。
　図６は、電子黒板装置の動作を示すフローチャートである。 [Operation of electronic blackboard device]
Next, the operation of the electronic blackboard device 1 will be described.
FIG. 6 is a flowchart showing the operation of the electronic blackboard device.
　電子黒板装置１の情報処理装置５０は、図２に示すように、表示面３１に地図Ｍ、半透明画像Ｃ１を表示させた状態において、図６に示すように、指Ｆにより表示面３１上の任意の位置が指示されたか否かを判断する（ステップＳ１）。そして、ステップＳ１において、指示されていないと判断した場合、所定時間経過後にステップＳ１の処理をし、指示されていると判断した場合、この指示されている位置を指示開始位置Ｐｂとして特定する（ステップＳ２）。
　この後、情報処理装置５０は、指示開始位置Ｐｂがスクロール選択領域Ａ１内か否かを判断する（ステップＳ３）。 As shown in FIG. 2, the information processing apparatus 50 of the electronic blackboard device 1 displays the map M and the translucent image C1 on the display surface 31, as shown in FIG. It is determined whether or not an arbitrary position is designated (step S1). If it is determined in step S1 that no instruction has been given, the process of step S1 is performed after a predetermined time has elapsed. If it is determined that an instruction has been given, the indicated position is specified as the instruction start position Pb ( Step S2).
Thereafter, the information processing apparatus 50 determines whether or not the instruction start position Pb is within the scroll selection area A1 (step S3).
　このステップＳ３において、情報処理装置５０は、スクロール選択領域Ａ１内であると判断した場合、指Ｆによる指示が継続されているか否かを判断する（ステップＳ４）。そして、ステップＳ４において、指示が継続されていないと判断した場合、処理を終了するか否かを判断し（ステップＳ５）、終了すると判断した場合に、処理を終了し、終了しないと判断した場合、ステップＳ１の処理をする。 In this step S3, when the information processing apparatus 50 determines that it is in the scroll selection area A1, it determines whether or not the instruction by the finger F is continued (step S4). If it is determined in step S4 that the instruction is not continued, it is determined whether or not to end the process (step S5). If it is determined that the process is to be ended, the process is ended and it is determined that the process is not ended. Step S1 is processed.
　一方、情報処理装置５０は、ステップＳ４において、指示が継続されていると判断した場合、指示が継続されたまま指Ｆが移動したか否かを判断する（ステップＳ６）。このステップＳ６において、移動していないと判断するとステップＳ４の処理をする。一方、ステップＳ６において、指Ｆが移動したと判断すると、指示開始位置Ｐｂの認識から所定時間経過した時点、または、指Ｆの移動開始から所定時間経過時点での指示位置を軌跡確定位置Ｑｃ（ｃは整数）として特定する（ステップＳ７）。この後、移動前の位置から軌跡確定位置Ｑｃまでの指示軌跡Ｔａに対応させて地図Ｍ（画像）をスクロールさせ（ステップＳ８）、ステップＳ４の処理をする。 On the other hand, if it is determined in step S4 that the instruction is continued, the information processing apparatus 50 determines whether or not the finger F has moved while the instruction is continued (step S6). If it is determined in step S6 that it has not moved, the process of step S4 is performed. On the other hand, if it is determined in step S6 that the finger F has moved, the designated position at the time when a predetermined time has elapsed from the recognition of the instruction start position Pb or when the predetermined time has elapsed from the start of movement of the finger F is determined as the locus determination position Qc ( c is an integer) (step S7). Thereafter, the map M (image) is scrolled in correspondence with the instruction locus Ta from the position before the movement to the locus determination position Qc (step S8), and the process of step S4 is performed.
　また、情報処理装置５０は、ステップＳ３において、指示開始位置Ｐｂがスクロール選択領域Ａ１内でない、すなわち描画選択領域Ａ２内であると判断した場合、指示開始位置Ｐｂに点を描き（ステップＳ９）、指Ｆによる指示が継続されているか否かを判断する（ステップＳ１０）。そして、指示が継続されていないと判断した場合、ステップＳ５の処理をし、指示が継続されていると判断した場合、指示が継続されたまま指Ｆが移動したか否かを判断する（ステップＳ１１）。このステップＳ１１において、移動していないと判断するとステップＳ１０の処理をし、移動したと判断すると、指示開始位置Ｐｂの認識から所定時間経過した時点、または、指Ｆの移動開始から所定時間経過時点での軌跡確定位置Ｑｃを特定して（ステップＳ１２）、移動前の位置から軌跡確定位置Ｑｃまでの指示軌跡Ｔａに沿った線Ｌを地図Ｍに重ねて表示させ（ステップＳ１３）、ステップＳ１０の処理をする。 If the information processing apparatus 50 determines in step S3 that the instruction start position Pb is not within the scroll selection area A1, that is, within the drawing selection area A2, a point is drawn at the instruction start position Pb (step S9). It is determined whether or not the instruction with the finger F is continued (step S10). If it is determined that the instruction is not continued, the process of step S5 is performed. If it is determined that the instruction is continued, it is determined whether or not the finger F is moved while the instruction is continued (step). S11). If it is determined in step S11 that it has not moved, the process of step S10 is performed, and if it is determined that it has moved, when a predetermined time has elapsed from the recognition of the instruction start position Pb, or when a predetermined time has elapsed since the start of movement of the finger F The trajectory fixed position Qc at is determined (step S12), and a line L along the instruction trajectory Ta from the position before the movement to the trajectory determined position Qc is displayed superimposed on the map M (step S13). Process.
［電子黒板装置の作用効果］
　以上の電子黒板装置１によれば、以下の作用効果が期待できる。
　（１）電子黒板装置１の情報処理装置５０は、地図Ｍを表示させる際に、スクロール選択領域Ａ１を設定して、このスクロール選択領域Ａ１と同じ形状の半透明画像Ｃ１をスクロール選択領域Ａ１に重ねて表示させる。そして、指Ｆが表示面３１を指示したときの指示軌跡Ｔａを認識して、この指示軌跡Ｔａの指示開始位置Ｐｂがスクロール選択領域Ａ１内の場合に、地図Ｍをスクロールさせる。一方、指示開始位置Ｐｂが描画選択領域Ａ２内の場合に、指示軌跡Ｔａと同じ形状の線Ｌを地図Ｍに重ねて描画する。
　このため、半透明画像Ｃ１を表示させることで、スクロール選択領域Ａ１内の地図Ｍが隠されることが無い。さらには、スクロール選択領域Ａ１と描画選択領域Ａ２とを利用者に区別させることで、スクロール機能を有していることを認識させることができ、スクロール操作を誘発させることができる。そして、指示開始位置Ｐｂをスクロール選択領域Ａ１内または描画選択領域Ａ２内にするだけで、地図Ｍのスクロール操作と線Ｌの描画操作とを選択できるので、スクロール操作と描画操作とを切り替える例えばボタン操作をする必要が無く、操作性を向上できる。また、スクロールさせる際に同じ位置を一定時間継続して指示する必要がないため、煩わしさを感じさせることがない。 [Effects of electronic blackboard device]
According to the electronic blackboard device 1 described above, the following effects can be expected.
(1) When displaying the map M, the information processing apparatus 50 of the electronic blackboard device 1 sets the scroll selection area A1, and the translucent image C1 having the same shape as the scroll selection area A1 is displayed in the scroll selection area A1. Overlapping display. Then, the instruction locus Ta when the finger F points to the display surface 31 is recognized, and the map M is scrolled when the instruction start position Pb of the instruction locus Ta is within the scroll selection area A1. On the other hand, when the instruction start position Pb is within the drawing selection area A2, a line L having the same shape as the instruction locus Ta is drawn on the map M.
For this reason, the map M in the scroll selection area A1 is not hidden by displaying the translucent image C1. Furthermore, by allowing the user to distinguish between the scroll selection area A1 and the drawing selection area A2, it can be recognized that the scroll function is provided, and a scroll operation can be induced. Since the scroll operation of the map M and the drawing operation of the line L can be selected simply by setting the instruction start position Pb within the scroll selection area A1 or the drawing selection area A2, for example, a button for switching between the scroll operation and the drawing operation. There is no need to operate, and operability can be improved. Moreover, since there is no need to continuously indicate the same position for a certain time when scrolling, there is no inconvenience.
　（２）電子黒板装置１は、指示開始位置Ｐｂが描画選択領域Ａ２内であり、かつ、指示軌跡Ｔａの一部がスクロール選択領域Ａ１に重なっている場合、指示軌跡Ｔａに沿った線Ｌを描画選択領域Ａ２とスクロール選択領域Ａ１とに描画する。
　このため、表示面３１の全領域に線Ｌを描画することができ、電子黒板装置１の利便性を向上できる。 (2) When the instruction start position Pb is in the drawing selection area A2 and a part of the instruction locus Ta overlaps the scroll selection area A1, the electronic blackboard apparatus 1 draws a line L along the instruction locus Ta. Drawing is performed in the drawing selection area A2 and the scroll selection area A1.
For this reason, the line L can be drawn on the entire area of the display surface 31, and the convenience of the electronic blackboard device 1 can be improved.
　（３）電子黒板装置１は、指示開始位置Ｐｂの認識から所定時間経過した時点、または、指Ｆの移動開始から所定時間経過時点での指示軌跡Ｔａに基づいて、スクロール処理や描画処理を実施する。
このため、電子黒板装置１は、利用者がスクロール操作と描画操作とを間違えた場合でも、指Ｆの移動中にスクロールや描画を実施するので、利用者に間違いをすぐに気づかせることができる。さらに、応答性がよいリアルタイムでのスクロールや描画を実現できる。さらに、指示軌跡Ｔａの指示開始位置Ｐｂがスクロール選択領域Ａ１内の場合に、地図Ｍを指示軌跡Ｔａと同じ形状、同じ方向、同じ長さの線に従ってスクロールさせるようにすることによって、スクロールも描画も指示軌跡Ｔａと同じ形状、同じ長さになるため、利用者には直感的に分かりやすく、操作性がいい。 (3) The electronic blackboard device 1 performs a scroll process and a drawing process based on the instruction trajectory Ta when a predetermined time has elapsed from the recognition of the instruction start position Pb or when a predetermined time has elapsed since the start of the movement of the finger F. To do.
For this reason, even if the user makes a mistake in the scrolling operation and the drawing operation, the electronic blackboard device 1 performs the scrolling and drawing while the finger F is moving, so that the user can immediately notice the mistake. . Furthermore, real-time scrolling and drawing with good responsiveness can be realized. Furthermore, when the instruction start position Pb of the instruction locus Ta is within the scroll selection area A1, scrolling is also drawn by causing the map M to scroll according to a line having the same shape, the same direction, and the same length as the instruction locus Ta. Since it has the same shape and the same length as the instruction locus Ta, it is easy for the user to understand intuitively and has good operability.
　（４）電子黒板装置１は、表示面３１の外縁にスクロール選択領域Ａ１を設定している。
　ここで、一般的に、表示面３１を見る場合、外縁よりも中央に注意が行きやすい。また、表示面３１に表示される地図Ｍや画像における重要な部分は、表示面３１の外縁ではなく中央に表示させるように操作されることが多い。このため、半透明画像Ｃ１が表示されていることによる違和感を覚えさせることなく、また、地図Ｍにおける重要部分の表示の視認性を落とすことなく、スクロール操作と描画操作との操作性を向上できる。 (4) The electronic blackboard device 1 sets the scroll selection area A <b> 1 on the outer edge of the display surface 31.
Here, in general, when viewing the display surface 31, it is easier to pay attention to the center than to the outer edge. Further, in many cases, an important part of the map M or image displayed on the display surface 31 is operated so as to be displayed in the center instead of the outer edge of the display surface 31. For this reason, it is possible to improve the operability between the scroll operation and the drawing operation without causing a sense of incongruity due to the display of the translucent image C1 and without reducing the visibility of the display of the important part on the map M. .
　（５）電子黒板装置１は、表示面３１の各辺に沿ってスクロール選択領域Ａ１を設定している。
　このため、電子黒板装置１に対する利用者の立つ位置や、利用者の背の高さによらず、スクロール操作と描画操作とを実施させることができる。 (5) The electronic blackboard device 1 sets the scroll selection area A1 along each side of the display surface 31.
For this reason, the scroll operation and the drawing operation can be performed regardless of the position where the user stands with respect to the electronic blackboard device 1 and the height of the user.
　（６）電子黒板装置１は、タッチパネル４０上での接触位置を表示面３１の指示位置として認識する。
　このため、利用者は指Ｆで直接操作することができるため、マウスやポインタデバイスあるいは光学式のポインタで指示位置を設定する構成と比べて操作性を向上できる。 (6) The electronic blackboard device 1 recognizes the contact position on the touch panel 40 as the indicated position on the display surface 31.
For this reason, since the user can directly operate with the finger F, the operability can be improved as compared with the configuration in which the pointing position is set with a mouse, a pointer device, or an optical pointer.
［他の実施形態］
　なお、本発明は前述の一実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良などは本発明に含まれるものである。 [Other Embodiments]
Note that the present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved.
　すなわち、図７に示すように、選択領域区別手段５３により、スクロール選択領域Ａ１と描画選択領域Ａ２との境界上に、境界線Ｃ２を表示させてもよい。このような構成でも、選択領域区別手段５３は、境界線Ｃ２の表示により、スクロール選択領域Ａ１と描画選択領域Ａ２とを区別可能、かつ、スクロール選択領域Ａ１内に表示中の地図Ｍを認識可能な状態に、地図Ｍの表示形態を設定することができ、上記実施形態と同様の作用効果を奏することができる。さらには、地図Ｍにおけるスクロール選択領域Ａ１内の部分をぼかして表示させてもよいし、描画選択領域Ａ２がカラー表示の場合には白黒表示させてもよい。また、スクロール選択領域Ａ１における描画選択領域Ａ２側の端部や、描画選択領域Ａ２におけるスクロール選択領域Ａ１側の端部の所定幅の領域に、さらには、スクロール選択領域Ａ１と描画選択領域Ａ２との境界上に、半透明画像を表示させてもよい。 That is, as shown in FIG. 7, the selection line discriminating means 53 may display a boundary line C2 on the boundary between the scroll selection area A1 and the drawing selection area A2. Even in such a configuration, the selection area discriminating means 53 can distinguish the scroll selection area A1 and the drawing selection area A2 from the display of the boundary line C2, and can recognize the map M being displayed in the scroll selection area A1. In this state, the display form of the map M can be set, and the same effect as the above embodiment can be obtained. Furthermore, the portion in the scroll selection area A1 in the map M may be displayed in a blurred manner, or may be displayed in black and white when the drawing selection area A2 is in color display. In addition, the end of the scroll selection area A1 on the drawing selection area A2 side, the end of the drawing selection area A2 on the scroll selection area A1 side, a predetermined width area, and the scroll selection area A1 and the drawing selection area A2 A semi-transparent image may be displayed on the boundary.
　また、スクロール選択領域Ａ１を表示面３１の外縁を構成する４辺のうちの３辺、２辺、１辺のみに設けてもよいし、外縁に沿って点在させて設けてもよい。さらには、スクロール選択領域Ａ１を表示面３１の外縁から離して、上記実施形態における描画選択領域Ａ２に対応する位置に設けてもよい。また、スクロール選択領域Ａ１の大きさや位置を、画像の種類、利用者による入力操作などにより変更可能にしてもよい。 Further, the scroll selection area A1 may be provided on only three sides, two sides, and one side of the four sides constituting the outer edge of the display surface 31, or may be provided in a dotted manner along the outer edge. Furthermore, the scroll selection area A1 may be provided away from the outer edge of the display surface 31 and at a position corresponding to the drawing selection area A2 in the above embodiment. Further, the size and position of the scroll selection area A1 may be changed by the type of image, an input operation by the user, and the like.
　さらに、指示軌跡Ｔａの形状によらず、指示開始位置Ｐｂが描画選択領域Ａ２の場合に、指示軌跡Ｔａ上の少なくとも１箇所に、あらかじめ設定された点や線や丸印などの図形あるいはテキストを表示させてもよい。また、指示開始位置Ｐｂが描画選択領域Ａ２の場合に、指示軌跡Ｔａに沿って線Ｌを描画する構成としたが、指示軌跡Ｔａに沿って過去に描画した線Ｌや図形などを消去する構成としてもよい。さらに、指示開始位置Ｐｂが描画選択領域Ａ２内であり、かつ、指示軌跡Ｔａの一部がスクロール選択領域Ａ１に重なっている場合、指示軌跡Ｔａのうち、スクロール選択領域Ａ１を除く部分の形状と同じ線を描画してもよい。 Furthermore, when the instruction start position Pb is the drawing selection area A2, regardless of the shape of the instruction locus Ta, a figure or text such as a preset point, line, or circle is added to at least one place on the instruction locus Ta. It may be displayed. Further, when the instruction start position Pb is the drawing selection area A2, the configuration is such that the line L is drawn along the instruction trajectory Ta, but the configuration is such that lines L and figures drawn in the past along the instruction trajectory Ta are deleted. It is good. Further, when the instruction start position Pb is in the drawing selection area A2 and a part of the instruction locus Ta overlaps the scroll selection area A1, the shape of the part other than the scroll selection area A1 in the instruction locus Ta The same line may be drawn.
　また、図８に示すような処理をしてもよい。
　すなわち、電子黒板装置１は、上記実施形態と同様のステップＳ１，Ｓ２の処理後に、指示が継続されたまま指Ｆ移動したか否かを判断し（ステップＳ２１）、移動したと判断した場合、指Ｆがタッチパネル４０から離れた位置を指示終了位置として特定する（ステップＳ２２）。このステップＳ２２の処理後、または、ステップＳ２１において指Ｆが指示開始位置Ｐｂから移動せずにタッチパネル４０から離れた場合、指示開始位置Ｐｂがスクロール選択領域Ａ１内か否かを判断する（ステップＳ３）。
　このステップＳ３において、スクロール選択領域Ａ１内であると判断した場合、指示軌跡Ｔａに対応させて地図Ｍをスクロールさせ（ステップＳ２３）、ステップＳ５の処理をする。なお、指Ｆが指示開始位置Ｐｂから移動しなかったため指示軌跡Ｔａを特定できなかった場合、地図Ｍをスクロールさせない。
　また、ステップＳ３において、指示開始位置Ｐｂが描画選択領域Ａ２内であると判断した場合、指示軌跡に沿った線Ｌを地図Ｍに重ねて表示させ（ステップＳ２４）、ステップＳ５の処理をする。なお、指Ｆが指示開始位置Ｐｂから移動しなかったため指示軌跡Ｔａを特定できなかった場合、指示開始位置Ｐｂに点を描画する。 Moreover, you may perform a process as shown in FIG.
That is, the electronic blackboard device 1 determines whether or not the finger F has been moved while the instruction is continued after the processing of steps S1 and S2 similar to the above embodiment (step S21). The position where the finger F is separated from the touch panel 40 is specified as the instruction end position (step S22). After the process of step S22 or when the finger F moves away from the touch start position Pb without moving from the start position Pb in step S21, it is determined whether or not the start position Pb is within the scroll selection area A1 (step S3). ).
If it is determined in step S3 that it is within the scroll selection area A1, the map M is scrolled in correspondence with the instruction locus Ta (step S23), and the process of step S5 is performed. Note that if the instruction trajectory Ta cannot be specified because the finger F has not moved from the instruction start position Pb, the map M is not scrolled.
If it is determined in step S3 that the instruction start position Pb is within the drawing selection area A2, the line L along the instruction locus is displayed superimposed on the map M (step S24), and the process of step S5 is performed. If the instruction trajectory Ta cannot be specified because the finger F has not moved from the instruction start position Pb, a point is drawn at the instruction start position Pb.
　そして、指示手段としての指やペンなどの指示物による指示位置を認識する方法として、音や電波あるいは可視光が指示物で反射あるいは遮蔽された状態に基づいて、指示位置を認識してもよい。このような反射あるいは遮蔽された状態に基づいて指示位置を認識する場合、指示手段が表示面から所定距離以内に接近したときに指示されたと判断することが好ましい。さらには、指示物に光や音あるいは電波を発信する構成を設け、指示物から発せられる光などの受光や受信の状態に基づいて、指示位置を算出してもよい。そして、指示手段としてのマウスなどでカーソルを移動させる場合、マウスの左クリックあるいは右クリックで指示されたと判断する。
　また、上述した各機能をプログラムとして構築したが、例えば回路基板などのハードウェアあるいは一つのＩＣ（Integrated Circuit）などの素子にて構成するなどしてもよく、いずれの形態としても利用できる。なお、プログラムや別途記録媒体から読み取らせる構成とすることにより、上述したように取扱が容易で、利用の拡大が容易に図れる。 Then, as a method for recognizing an instruction position by an indicator such as a finger or a pen as an instruction means, the instruction position may be recognized based on a state where sound, radio waves, or visible light is reflected or shielded by the indicator. . When recognizing the pointing position based on such a reflected or shielded state, it is preferable to determine that the pointing unit has been instructed when the pointing unit approaches within a predetermined distance from the display surface. Furthermore, a configuration for transmitting light, sound, or radio waves to the indicator may be provided, and the indicated position may be calculated based on the state of receiving or receiving light such as light emitted from the indicator. When the cursor is moved with a mouse or the like as an instruction means, it is determined that an instruction is given by a left or right mouse click.
Each function described above is constructed as a program. However, for example, it may be configured by hardware such as a circuit board or an element such as a single integrated circuit (IC), and any form can be used. Note that, by using a configuration that allows reading from a program or a separate recording medium, as described above, handling is easy, and usage can be easily expanded.
　その他、本発明の実施の際の具体的な構造および手順は、本発明の目的を達成できる範囲で他の構造などに適宜変更できる。 In addition, the specific structure and procedure for carrying out the present invention can be appropriately changed to other structures and the like within a range in which the object of the present invention can be achieved.
［実施形態の作用効果］
　上記したように、電子黒板装置１は、地図Ｍを表示させる際に、スクロール選択領域Ａ１を設定して、このスクロール選択領域Ａ１に半透明画像Ｃ１を重ねて表示させる。そして、指Ｆが表示面３１を指示したときの指示開始位置Ｐｂがスクロール選択領域Ａ１内の場合に、地図Ｍをスクロールさせ、描画選択領域Ａ２内の場合に、指示軌跡Ｔａと同じ形状の線Ｌを地図Ｍに重ねて描画する。
　このため、半透明画像Ｃ１を表示させることで、スクロール選択領域Ａ１内の地図Ｍが隠されることが無い。さらには、スクロール選択領域Ａ１と描画選択領域Ａ２とを利用者に区別させることで、スクロール機能を有していることを認識させることができ、スクロール操作を誘発させることができる。そして、指示開始位置Ｐｂをスクロール選択領域Ａ１内または描画選択領域Ａ２内にするだけで、地図Ｍのスクロール操作と線Ｌの描画操作とを選択できるので、スクロール操作と描画操作とを切り替える例えばボタン操作をする必要が無く、操作性を向上できる。
　本願の情報処理装置は、表示手段の表示面における所定位置が指示手段で指示された際に、この指示位置に対応する処理をする情報処理装置であって、前記表示面の一部の領域をスクロール選択領域として設定するとともに、前記スクロール選択領域以外の領域を描画選択領域として設定する処理選択領域設定手段と、前記スクロール選択領域と前記描画選択領域とを区別可能、かつ、前記スクロール選択領域内に表示中の前記画像を認識可能な状態に、前記画像の表示形態を設定する選択領域区別手段と、前記指示手段が前記表示面を指示している状態を維持しつつ移動した指示軌跡を認識する指示軌跡認識手段と、前記指示手段の指示開始位置が前記スクロール選択領域内の場合に、前記指示軌跡と同じ形状、同じ方向、同じ長さの線に従って前記画像をスクロールさせるスクロール処理を実施し、前記指示開始位置が前記描画選択領域内の場合に、前記指示軌跡と同じ位置に前記指示軌跡を前記画像に重ねて表示させる描画処理を実施する処理実施手段と、を具備したことを特徴とする。
　指示開始位置をスクロール選択領域とするか、描画選択領域内とするかによって、スクロール処理と描画処理を選択することができるので、スクロール処理と描画処理を容易に切替えることができ、操作しやすい。しかも、スクロール処理、描画処理ともに指示軌跡と同じ形状、同じ方向、同じ長さにて処理されるため直感的に分りやすい。
　さらに、前記選択領域区別手段は、前記スクロール選択領域と前記描画選択領域の境界近傍、あるいは前記スクロール選択領域の一部または全体に表示中の画像に半透明な半透明画像を重ねて表示させることを特徴とする。このため、利用者はスクロール選択領域、描画選択領域を容易に認識することができる。しかも、スクロール選択領域、描画選択領域ともに表示領域として使うことができるばかりでなく、指示手段の指示開始位置を除いてスクロール選択領域、描画選択領域をともにスクロール処理、描画処理に使うことができる。ここで、半透明画像の透過率としては、３０％～６０％が好ましい。ただし、半透明画像を介した画像の認識度は、個人により、また表示されている画像の色により異なるため、半透明画像の透過率を変更可能な構成とすることが好ましい。
　さらに、指示軌跡認識手段は、前記指示開始位置の認識から所定時間経過した時点、または、前記指示手段の移動開始から所定時間経過した時点における前記指示軌跡を認識することを特徴とする。所定時間を充分短い時間にすることによって実質的に指示手段の軌跡に連動してリアルタイムでスクロール処理、描画処理を行うことができる。指示手段の軌跡に連動してリアルタイムでスクロール処理、描画処理を行うことができるので、利用者がスクロール処理と描画処理を誤って操作した場合でも、すぐに誤りに気づいて操作をやりなおすことができる。 [Effects of Embodiment]
As described above, when displaying the map M, the electronic blackboard device 1 sets the scroll selection area A1 and displays the semitransparent image C1 in an overlapping manner on the scroll selection area A1. When the instruction start position Pb when the finger F indicates the display surface 31 is within the scroll selection area A1, the map M is scrolled. When the finger F is within the drawing selection area A2, a line having the same shape as the instruction locus Ta L is drawn on the map M.
For this reason, the map M in the scroll selection area A1 is not hidden by displaying the translucent image C1. Furthermore, by allowing the user to distinguish between the scroll selection area A1 and the drawing selection area A2, it can be recognized that the scroll function is provided, and a scroll operation can be induced. Since the scroll operation of the map M and the drawing operation of the line L can be selected simply by setting the instruction start position Pb within the scroll selection area A1 or the drawing selection area A2, for example, a button for switching between the scroll operation and the drawing operation. There is no need to operate, and operability can be improved.
The information processing apparatus of the present application is an information processing apparatus that performs processing corresponding to a designated position when a predetermined position on the display surface of the display means is designated by the instruction means. A process selection area setting means for setting a scroll selection area and an area other than the scroll selection area as a drawing selection area can be distinguished from the scroll selection area and the drawing selection area, and within the scroll selection area A selection area discriminating means for setting the display form of the image in a state where the image being displayed can be recognized, and an indication trajectory that has moved while the instruction means indicates the display surface. And when the instruction start position of the instruction means is within the scroll selection area, the line has the same shape, the same direction and the same length as the instruction locus. Then, a scroll process for scrolling the image is performed, and when the instruction start position is within the drawing selection area, a drawing process for displaying the instruction locus on the image at the same position as the instruction locus is performed. And a processing execution means.
Since the scroll process and the drawing process can be selected depending on whether the instruction start position is the scroll selection area or the drawing selection area, the scroll process and the drawing process can be easily switched, and the operation is easy. Moreover, since both the scroll process and the drawing process are processed with the same shape, the same direction, and the same length as the instruction locus, it is easy to understand intuitively.
Further, the selection area discriminating unit displays a translucent translucent image superimposed on an image being displayed in the vicinity of the boundary between the scroll selection area and the drawing selection area, or in a part or the whole of the scroll selection area. It is characterized by. For this reason, the user can easily recognize the scroll selection area and the drawing selection area. In addition, both the scroll selection area and the drawing selection area can be used as display areas, and both the scroll selection area and the drawing selection area can be used for scroll processing and drawing processing except for the instruction start position of the instruction means. Here, the transmittance of the translucent image is preferably 30% to 60%. However, since the degree of recognition of an image via a semi-transparent image varies depending on the individual and the color of the displayed image, it is preferable that the transmissivity of the semi-transparent image be changed.
Further, the instruction locus recognition means recognizes the instruction locus at a time when a predetermined time has elapsed from the recognition of the instruction start position or when a predetermined time has elapsed from the start of movement of the instruction means. By making the predetermined time sufficiently short, scroll processing and drawing processing can be performed in real time in conjunction with the locus of the instruction means. Since it is possible to perform scroll processing and drawing processing in real time in conjunction with the trajectory of the instruction means, even if the user mistakenly operates scroll processing and drawing processing, it is possible to immediately recognize the error and redo the operation. .
