Description

表示装置および表示方法Display device and display method
　本発明は、ディスプレイを備えた表示装置および表示方法に関する。 The present invention relates to a display device having a display and a display method.
　ディスプレイを備えた表示装置において、装置全体の大きさを抑えながら大画面化を実現するため、装置の額縁にあたる部分の幅を狭くする狭額縁化が進んでいる。しかし、携帯可能な表示装置における額縁は、そこに指を置くことで、画面を指で隠してしまうことを防いだり、さらにそのディスプレイがタッチパネルも兼ねている場合には意図しない接触反応を防いだりする役割も果たしている。したがって、額縁を指の幅より極端に狭くした表示装置は、持ちづらかったり誤接触を引き起こしたりする恐れがあった。 In a display device equipped with a display, in order to realize a large screen while suppressing the size of the entire device, a narrowing of the frame to narrow the width of the portion corresponding to the frame of the device is progressing. However, the frame in a portable display device prevents the screen from being hidden by placing a finger on it, and prevents an unintended contact reaction when the display also serves as a touch panel. It also plays a role. Therefore, a display device whose frame is extremely narrower than the width of the finger may be difficult to hold or cause erroneous contact.
　そこで、特許文献１のように、タッチパネルの端部に指が触れた場合に画面表示の縮小や移動を行って、表示が指で隠れないようにするモニタ付きカメラが考えられている。このカメラは、別の見方をすると、主表示の周りの領域に表示された仮想的な額縁（以下、「額縁表示」という）の形を変化させるものであると考えることもできる。 Therefore, as in Patent Document 1, there is a camera with a monitor that reduces or moves the screen display when a finger touches the end of the touch panel so that the display is not hidden by the finger. From another viewpoint, this camera can be considered to change the shape of a virtual frame (hereinafter referred to as “frame display”) displayed in an area around the main display.
　一方、狭額縁であることを生かして、表示装置の画面をつなげるように複数近接させて用いたい場合、近接している部分に額縁表示が行われていると、画面間で大きな隔たりができてしまうため、閲覧の邪魔になってしまう。 On the other hand, taking advantage of the fact that it is a narrow frame, if you want to use multiple screens close together so that the screens of the display devices are connected, if there is a frame display in the adjacent part, there will be a large gap between the screens. As a result, it becomes an obstacle to browsing.
　そのため、表示装置単体で利用するときは額縁表示を行い、複数の表示装置を近接させて用いるときは近接部分の額縁表示を消去するような仕組みが必要となる。 For this reason, a frame display is required when the display device is used alone, and a frame display is deleted when a plurality of display devices are used close to each other.
特許第４１７８４８４号公報Japanese Patent No. 4178484
　しかしながら、特許文献１に記載の装置はあくまで表示装置単体の持ち方によって額縁表示の変更を行うものであって、複数の装置を近接させて用いる場合に適用することはできなかった。 However, the device described in Patent Document 1 changes the frame display depending on how the display device is held alone, and cannot be applied when a plurality of devices are used in close proximity.
　そこで本発明は、表示装置同士の位置関係に応じて額縁表示を変更することで、単体で利用するときと複数を近接させて利用するときの両方において使いやすい表示装置を提供することを目的とする。 Therefore, the present invention aims to provide a display device that is easy to use both when used alone and when used in close proximity by changing the frame display according to the positional relationship between the display devices. To do.

Furthermore, the discontinuity of the frame display that occurs because the distance between the proximity sensors is wide can be made inconspicuous.
　本発明にかかる第５の表示装置は、第１から第４のいずれか一つの発明の構成に加え、前記ディスプレイ上における接触の位置を検知する接触検知手段を備え、前記額縁表示の領域が接触無効領域も兼ねることを特徴としている。 According to a fifth display device of the present invention, in addition to the configuration of any one of the first to fourth inventions, the fifth display device includes contact detection means for detecting a contact position on the display, and the frame display area is in contact with the display area.

When the shapes are the same, at least one of the other display devices is instructed to be pulled apart and brought close again.
　これにより、複数の表示装置が同時かつ同じ近接領域の形で接近した場合に、どちらに近接しているのがどちらの表示装置なのかを区別することができる。 Thus, when a plurality of display devices approach at the same time in the form of the same proximity region, it is possible to distinguish which display device is close to which display device.
　本発明にかかる表示方法は、ディスプレイ上の外周部の少なくとも一部分に主表示と視覚的に区別された額縁表示を行う画像表示ステップを含む表示方法において、他の表示装置が近接していることを検知する近接検知ステップと、前記近接検知ステップにより検知された情報によって前記額縁表示を変更する表示変更ステップと、を含むことを特徴としている。 The display method according to the present invention is a display method including an image display step for displaying a frame that is visually distinguished from the main display on at least a part of the outer peripheral portion on the display.

　図１は本発明を適用した表示装置１００であり、図２はその機能ブロック図である。表示装置１００の正面部にはディスプレイ１０５が備えられている。筐体１１０は表示装置１００の裏面と側面の全体、およびディスプレイ１０５（表示面）の一部を覆っているが、ディスプレイ１０５が筐体１１０によって隠される幅は人間の指の幅よりも極端に狭くなっている。 FIG. 1 shows a display device 100 to which the present invention is applied, and FIG. 2 is a functional block diagram thereof. A display 105 is provided on the front portion of the display device 100. The housing 110 covers the entire back surface and side surface of the display device 100 and a part of the display 105 (display surface). However, the width of the display 105 hidden by the housing 110 is extremely larger than the width of a human finger. It is narrower.
　表示装置１００の外周部付近には、近接検知手段として、被検出体１１５（１１５ａ）を内蔵した複数の近接センサ１２０が設けられており、他の表示装置に設けられた被検出体１１５ｂの近接を検出することができる。なお、近接センサ１２０が被検出体１１５を検知できる距離の限界（感度）は、後述する額縁表示１２５の幅（本実施例では例えば２ｃｍ）程度であることが望ましい。これより大幅に大きいと（例えば４ｃｍ）、接触部分から離れた部分までも近接と検知してしまう。一方で、大幅に小さいと（例えば０．５ｃｍ）、表示装置同士を完全に接触させた状態でも近接を検知できない危険性がある。 In the vicinity of the outer periphery of the display device 100, a plurality of proximity sensors 120 including a detection target 115 (115a) are provided as proximity detection means, and the proximity of the detection target 115b provided in another display device is provided. Can be detected. It should be noted that the distance limit (sensitivity) that the proximity sensor 120 can detect the detection object 115 is desirably about the width of a frame display 125 (for example, 2 cm in this embodiment) described later. If it is significantly larger than this (for example, 4 cm), even a part away from the contact part will be detected as close. On the other hand, if it is significantly small (for example, 0.5 cm), there is a risk that proximity cannot be detected even when the display devices are in complete contact with each other.
　さらに、表示装置１００の外周部以外の部分にも複数の被検出体１１５が設けられている。各々の被検出体１１５および近接センサ１２０の間隔は、実現したい額縁表示の精度のレベルに応じて調整すればよいが、近接センサ１２０が同じ表示装置内の被検出体１１５を誤って検出してしまうことを防ぐために、近接センサ１２０の感度（本実施例では２ｃｍ程度）よりも大きい（たとえば３ｃｍ）距離であることが望ましい。 Furthermore, a plurality of detected bodies 115 are provided in portions other than the outer peripheral portion of the display device 100. The interval between each detected object 115 and the proximity sensor 120 may be adjusted according to the level of accuracy of the frame display to be realized. However, the proximity sensor 120 detects the detected object 115 in the same display device by mistake. In order to prevent this, it is desirable that the distance be larger (for example, 3 cm) than the sensitivity of the proximity sensor 120 (about 2 cm in this embodiment).
　ディスプレイ１０５には、他の表示装置と近接していない状態においては、外周部に把持領域として十分な幅（例えば２ｃｍ）の額縁表示１２５が、その内側の主表示領域１２７と区別できるように色を変えて表示されている。主表示領域１２７の表示はこの額縁表示１２５の領域には表示されないため、表示装置１００を手で持って閲覧・操作する場合には、指をこの額縁表示１２５の領域に置くことにより安定して把持することが可能となる。近接センサ１２０の情報は近接検出処理部１６０を通じて中央情報処理部１５０に送られ、画像表示手段および表示変更手段としての表示制御部１５５を通じて、額縁表示１２５を変化させるために利用される。 When the display 105 is not in proximity to other display devices, the frame display 125 having a sufficient width (for example, 2 cm) as a gripping region on the outer peripheral portion is colored so that it can be distinguished from the main display region 127 inside. Is displayed. Since the display of the main display area 127 is not displayed in the area of the frame display 125, when viewing and operating the display device 100 by hand, the finger can be stably placed by placing the finger in the area of the frame display 125. It can be gripped. Information of the proximity sensor 120 is sent to the central information processing unit 150 through the proximity detection processing unit 160, and is used to change the frame display 125 through the display control unit 155 as an image display unit and a display change unit.
　なお、本実施例では、ディスプレイ１０５が筐体１１０によって隠される幅を人間の指の幅より極端に狭いものとしたが、完全に幅が無い場合や、逆に指の幅より太いようなものであっても良い。 In the present embodiment, the width of the display 105 hidden by the housing 110 is extremely narrower than the width of a human finger. However, the width of the display 105 is thicker than the width of the finger. It may be.
　また、本実施例では額縁表示１２５を全外周に表示しているが、上下部分のみといったような、一部分に表示するものであっても良い。 In the present embodiment, the frame display 125 is displayed on the entire outer periphery, but it may be displayed on a part such as only the upper and lower parts.
　次に、図３のフローチャートおよび図４を用いて、この表示装置１００ａが同様の構成を持つ他の表示装置１００ｂと同一平面内で隣接するように近接した際の動作を説明する。 Next, with reference to the flowchart of FIG. 3 and FIG. 4, an operation when the display device 100a is adjacent to the other display device 100b having the same configuration so as to be adjacent to each other in the same plane will be described.
　図４（Ａ）のように、表示装置１００ａに表示装置１００ｂが近接した状態になると、ステップＳ１０１において、表示装置１００ａ、１００ｂの外周部に設けられた近接センサ１２０（図示せず、以下同様）が相手の表示装置の外周部に設けられた被検出体１１５（図示せず、以下同様）の近接を互いに検知し、当該近接部分に表示されている額縁表示を消去する（ステップＳ１０２）。なお、近接部分に表示されている額縁表示とは、近接を検知した近接センサを中心とし、隣接する近接センサとの中間地点を端部とする領域のことであり、例えば図１の近接センサ１２０ｎが近接を検知した場合は、額縁表示１２５ｎの領域を指す。 As shown in FIG. 4A, when the display device 100b comes close to the display device 100a, in step S101, the proximity sensor 120 provided on the outer periphery of the display devices 100a and 100b (not shown, the same applies hereinafter). Detects the proximity of detected bodies 115 (not shown, the same applies hereinafter) provided on the outer periphery of the display device of the other party, and erases the frame display displayed in the proximity portion (step S102). Note that the frame display displayed in the proximity portion is a region centered on the proximity sensor that detects proximity and has an end point at an intermediate point between adjacent proximity sensors. For example, the proximity sensor 120n in FIG. Indicates a region of the frame display 125n.
　その際、ただ単に近接部分の額縁表示を消去してしまうと、図４（Ｂ）のように額縁表示が不連続な領域１２６が存在してしまうため、図４（Ｃ）のように額縁表示消去領域１３０の両端から額縁の幅（本実施例では２ｃｍ）にあたる長さだけ除くことで消去領域を短くして、額縁表示の連続性を高めるようにしても良い。また、図４（Ｄ）のように、額縁表示１２５が段階的に消えていくようにグラデーションをかけて表示しても良い。 At that time, if the frame display of the adjacent portion is simply erased, there will be a region 126 where the frame display is discontinuous as shown in FIG. 4B, so that the frame display as shown in FIG. 4C. The erasing area may be shortened by removing only the length corresponding to the width of the frame (2 cm in this embodiment) from both ends of the erasing area 130, and the continuity of the frame display may be improved. Further, as shown in FIG. 4D, the frame display 125 may be displayed with gradation so that the frame display 125 disappears step by step.
　このようにして近接部分の額縁表示のみを消去することにより、二つの表示装置を一つの大きな表示装置と見たときの外周部にのみ額縁表示を行うことができる。 In this way, by deleting only the frame display of the adjacent portion, the frame display can be performed only on the outer peripheral portion when the two display devices are regarded as one large display device.
　なお、額縁表示消去領域１３０には、一辺の額縁表示が完全に消去された場合は主表示を額縁表示消去領域１３０の方向に引き伸ばしたものを表示しても良いし、そうではない場合は背景画像を表示するようにしても良い。 The frame display deletion area 130 may display the main display expanded in the direction of the frame display deletion area 130 when the frame display on one side is completely deleted, or the background display otherwise. An image may be displayed.
　一方で、表示装置１００ａと表示装置１００ｂが離れ、ステップＳ１０１において、近接センサ１２０が相手の表示装置の近接を検出できなくなると、額縁表示消去領域１３０に再び額縁表示１２５を行う（ステップＳ１０３）。 On the other hand, if the display device 100a and the display device 100b are separated and the proximity sensor 120 cannot detect the proximity of the partner display device in step S101, the frame display 125 is displayed again in the frame display erasure area 130 (step S103).
　このようにして表示装置１００ａ、１００ｂが近接していないときには額縁表示を行い、近接しているときには近接部分の額縁表示を行わないようにすることで、単体で使用するときは持ちやすく、複数隣接させて用いるときは複数の表示装置があたかも一つの大きな表示装置になったかのような印象を与えることができる。 In this way, by displaying the frame when the display devices 100a and 100b are not close to each other and by not displaying the frame of the adjacent portion when the display devices 100a and 100b are close to each other, the display devices 100a and 100b are easy to hold when used alone. When used in such a manner, it is possible to give an impression as if a plurality of display devices have become one large display device.
　次に、図５を用いて、表示装置１００ａの上側に表示装置１００ｂの一部が重なるように近接した場合を説明する。 Next, a case where the display device 100b is close to the display device 100a so as to partially overlap the display device 100a will be described with reference to FIG.
　なお、表示装置１００ａの厚さは、近接センサ１２０の感度（本実施例では２ｃｍ）の半分よりも小さい（例えば０．８ｃｍ）ものとする。 In addition, the thickness of the display device 100a is assumed to be smaller (for example, 0.8 cm) than half of the sensitivity of the proximity sensor 120 (2 cm in this embodiment).
　この場合、表示装置１００ａ、１００ｂの外周部に設けられた近接センサ１２０が相手の表示装置の外周部及び内部の被検出体１１５を検出するため、この情報を用いて近接部分の額縁表示を消去すれば、二つの表示装置を一つの大きな表示装置と見たときの外周部にのみ額縁表示を行うことができる。 In this case, since the proximity sensor 120 provided on the outer peripheral portion of the display device 100a, 100b detects the outer peripheral portion of the other display device and the detected object 115 inside, the frame display of the adjacent portion is erased using this information. Then, the frame display can be performed only on the outer peripheral portion when the two display devices are regarded as one large display device.
　その際、ただ単に近接部分の額縁表示を消去してしまうと、図５（Ｂ）のように額縁表示が不連続な領域１２６が存在してしまうため、先述の隣接するように近接した場合で説明したのと同様に、図５（Ｃ）のように、額縁表示消去領域１３０の両端を額縁表示の幅（本実施例では２ｃｍ）にあたる長さだけ除くことで消去領域を短くすれば、額縁表示の連続性を高めることができる。ただ、図６（Ａ）のように斜めに重なっている場合は、図６（Ｂ）のように額縁表示消去領域１３０の両端を額縁表示の幅だけ短くしても、不連続な領域１２６が残ってしまう。そこで、図６（Ｃ）のように、額縁表示１２５が段階的に消えていくようにグラデーションをかけて表示すれば、額縁表示の不連続さを目立たなくすることができる。 At that time, simply erasing the frame display of the adjacent portion will cause a region 126 where the frame display is discontinuous as shown in FIG. 5B. As described above, as shown in FIG. 5C, if the erase area is shortened by removing the both ends of the frame display erase area 130 by a length corresponding to the width of the frame display (2 cm in this embodiment), Display continuity can be improved. However, if the frames overlap diagonally as shown in FIG. 6A, even if both ends of the frame display erase region 130 are shortened by the width of the frame display as shown in FIG. It will remain. Therefore, as shown in FIG. 6C, if the frame display 125 is displayed with gradation so that the frame display 125 disappears step by step, the discontinuity of the frame display can be made inconspicuous.
　またこのグラデーションによる方法は、近接センサ同士の間隔が広いことに起因して、表示装置同士を近接させた際の額縁表示が不連続になってしまう場合においても、その不連続さを目立たなくさせるのに有効である。 In addition, this gradation method makes the discontinuity inconspicuous even when the frame display becomes discontinuous when the display devices are brought close to each other due to the wide interval between the proximity sensors. It is effective.
　なお、図５（Ｂ）（Ｃ）および図６（Ｂ）（Ｃ）においては、重なりの下側にある表示装置１００ａにおいても、重なりの上側にある表示装置１００ｂと同様に、近接部分における額縁表示の変更が行われている。 In FIGS. 5B, 6C and 6B, in the display device 100a on the lower side of the overlap as well as the display device 100b on the upper side of the overlap, the frame in the proximity portion The display has been changed.
　本実施例に記載の形態によれば、図７（Ａ）に示したように、表示装置１００ａの上部に表示装置１００ｂが完全に含まれるように近接した場合も、同じ処理により、図７（Ｂ）のように表示装置１００ｂの全外周の額縁表示を消去することができる。 According to the form described in the present embodiment, as shown in FIG. 7A, even when the display device 100b is close to the upper portion of the display device 100a, the same processing is performed as shown in FIG. As shown in B), the frame display on the entire outer periphery of the display device 100b can be erased.
　さらにこの形態によれば、図８（Ａ）に示したように、３つ以上の表示装置が近接状態にある場合や、表示装置同士が交差している場合（例えば、交差領域１２８）、表示装置が長方形以外の多角形や曲線を含む形である場合（例えば、曲線接触領域１２９）にも、図８（Ｂ）のように、近接部分の額縁表示の変更を行うことができる。 Furthermore, according to this embodiment, as shown in FIG. 8A, when three or more display devices are in the proximity state or when the display devices cross each other (for example, the intersecting region 128), the display is performed. Even when the device has a shape including a polygon other than a rectangle or a curve (for example, the curve contact region 129), the frame display of the proximity portion can be changed as shown in FIG. 8B.
　加えて、図９（Ａ）および（Ｂ）に示したように、本実施例のディスプレイは背景が透けて見えるシースルー型であっても良い。表示装置１００の構成では、重なりの上側の表示装置１００ｂにおいて額縁表示消去領域１３０ｂが作られることに加え、重なりの下側の表示装置１００ａにおいても額縁表示消去領域１３０ａが作られるため、シースルー型であっても外部領域と接している部分のみに額縁表示を行えることになる。 In addition, as shown in FIGS. 9A and 9B, the display of this embodiment may be a see-through type in which the background can be seen through. In the configuration of the display device 100, in addition to the frame display erase region 130b being created in the upper display device 100b of the overlap, the frame display erase region 130a is also created in the lower display device 100a of the overlap. Even if it exists, the frame display can be performed only on the portion in contact with the external area.
　また、上記の例によらず、一部でも近接が検知されたときは外周部すべての額縁表示を行わないようにしても良い。この方法は、複数の表示装置を近接させたまま机の上に置いておく場合などにおいて、画面表示を広く行えるという利点がある。 In addition, regardless of the above example, when the proximity is detected even in part, the frame display of the entire outer periphery may not be performed. This method has an advantage that the screen display can be widely performed, for example, when a plurality of display devices are placed close to each other on a desk.
　さらに、本実施例では、適切な額縁表示を両表示装置間で通信を行うことなく実現している。このため、表示装置の構造を簡略化することができるのも利点である。 Furthermore, in this embodiment, an appropriate frame display is realized without performing communication between both display devices. For this reason, it is also an advantage that the structure of the display device can be simplified.
　なお、本実施例においては額縁表示を消去することについて述べたが、図１０（Ｂ）に示したような近接部分の額縁表示の模様を変更するものや、近接部分の額縁表示の幅、色、透明度などを消去しない程度に変更するものであっても良い。また、図１０（Ｃ）のように、近接部分に加え、近接部分以外の額縁表示も変更するようにしても良い。この場合においても、複数の表示装置を一つの大きな表示装置と見たときの外周部に同種の額縁表示を行うことで、複数の表示装置が一体化したかのような感覚をユーザに与えることができる。 In this embodiment, the display of the frame display is described. However, the frame display pattern of the proximity portion as shown in FIG. 10B is changed, the frame display width and color of the proximity portion are changed. The transparency may be changed so as not to be erased. Further, as shown in FIG. 10C, the frame display other than the proximity portion may be changed in addition to the proximity portion. Even in this case, it is possible to give the user a feeling as if the plurality of display devices are integrated by performing the same kind of frame display on the outer periphery when the plurality of display devices are viewed as one large display device. .
　さらには、本実施例においては他の表示装置の近接を検知するために、複数の被検出体と、被検出体を検出するための複数の近接センサを用いたが、圧力を検知する圧力センサや、金属全般を検出する金属センサ、赤外線による近接センサ等を用いて近接を検知しても良い。 Furthermore, in this embodiment, a plurality of detected objects and a plurality of proximity sensors for detecting the detected objects are used to detect the proximity of other display devices. Alternatively, proximity may be detected using a metal sensor for detecting all metals, a proximity sensor using infrared rays, or the like.
　図１１は実施例１の表示装置１００のディスプレイ１０５の代わりに接触検知手段としてのタッチパネル２０５およびタッチ検出部２１０を備え、さらに近接通信制御部２１４および近接通信送受信部２１５を加えた表示装置２００を表す機能ブロック図である。その他の部分は実施例１の表示装置１００と同一あるため、同一のものについては同じ符号を用いて説明を行う。 FIG. 11 shows a display device 200 that includes a touch panel 205 and a touch detection unit 210 as contact detection means instead of the display 105 of the display device 100 of the first embodiment, and further includes a proximity communication control unit 214 and a proximity communication transmission / reception unit 215. It is a functional block diagram to represent. Since other parts are the same as those of the display device 100 of the first embodiment, the same parts will be described using the same reference numerals.
　タッチパネル２０５はディスプレイとしての機能も備えるため、表示装置２００の外観は図１と同様である。このタッチパネル２０５およびタッチ検出部２１０により、タッチパネル上の複数点の接触操作を検出することができる。 Since the touch panel 205 also has a display function, the appearance of the display device 200 is the same as that in FIG. The touch panel 205 and the touch detection unit 210 can detect a plurality of contact operations on the touch panel.
　通信手段としての近接通信送受信部２１５は表示装置２００の内部に設けられており、他の表示装置の近接通信送受信部２１５ｂが近くにあるとき（例えば、十数ｃｍ程度以内の距離）に通信を行うことができる。具体的な近接通信の規格としてはＮＦＣ（Ｎｅａｒ　Ｆｉｅｌｄ　Ｃｏｍｍｕｎｉｃａｔｉｏｎ）などが考えられるが、これに限るものではない。 The proximity communication transmitting / receiving unit 215 as a communication unit is provided inside the display device 200, and performs communication when the proximity communication transmitting / receiving unit 215b of another display device is in the vicinity (for example, a distance within about several tens of centimeters). It can be carried out. A specific near field communication standard may be NFC (Near Field Communication), but is not limited thereto.
　また、本実施例で近接通信を用いるのは、あらかじめ通信の認証を行っていない機器同士が簡単につながることができるという点に加え、遠距離に存在する無関係の機器へのデータ転送を防ぐことができるというセキュリティ面での利点があるためであるが、通信の認証を行わせる場合やセキュリティ面を意識する必要がない場合は、近接通信以外の通信手段を用いるようにしても良い。 In addition, proximity communication is used in this embodiment, in addition to being able to easily connect devices that have not been previously authenticated for communication, in addition to preventing data transfer to unrelated devices that exist at a long distance. This is because there is an advantage in terms of security that the communication can be performed, but when authentication of communication is performed or when there is no need to be aware of the security, communication means other than proximity communication may be used.
　画面上の外周部には、実施例１の図１と同様に、他の表示装置と近接していない状態においては、額縁表示１２５がその内側の主表示領域１２７と区別できるように表示されている。ここで、額縁表示１２５は接触無効領域も兼ねているため、この表示装置２００を手で持って閲覧・操作する場合には、指をこの額縁表示１２５に置くことにより誤操作を引き起こすことなく、安定して把持することが可能となる。 As in FIG. 1 of the first embodiment, the frame display 125 is displayed on the outer periphery of the screen so as to be distinguishable from the main display area 127 inside the display device when not in proximity to other display devices. Yes. Here, since the frame display 125 also serves as a contact invalid area, when viewing and operating the display device 200 by hand, placing the finger on the frame display 125 is stable without causing an erroneous operation. And can be gripped.
　次に、図１２のフローチャートを用いて、この表示装置２００ａが同様の構成を持つ別の表示装置２００ｂと近接した際の動作を説明する。 Next, the operation when the display device 200a comes close to another display device 200b having the same configuration will be described using the flowchart of FIG.
　表示装置２００ａと表示装置２００ｂが一か所でも近接した状態になると、ステップＳ２０１において、表示装置２００ａ、２００ｂの外周部に設けられた近接センサ１２０が相手の表示装置の被検出体１１５の近接を互いに検知し、近接通信送受信部２１５が相手の表示装置と通信を行うための準備段階に入る（ステップＳ２０２、Ｓ２０３）。準備が完了し通信が確立されたら（ステップＳ２０４）、近接部分のみの額縁表示を消去し（ステップＳ２０５）、その額縁表示消去領域１３０を接触有効領域とする。 When the display device 200a and the display device 200b are close to each other, in step S201, the proximity sensor 120 provided on the outer periphery of the display devices 200a and 200b detects the proximity of the detected object 115 of the partner display device. Detecting each other, the proximity communication transmitting / receiving unit 215 enters a preparation stage for communicating with the display device of the other party (steps S202 and S203). When the preparation is completed and communication is established (step S204), the frame display of only the proximity portion is deleted (step S205), and the frame display deletion area 130 is set as the contact effective area.
　なお、額縁表示１２５を、グラデーションをかけて段階的に消えていくようにした場合は、表示の濃さが例えば５０％であるところを境界として接触有効領域と接触無効領域に分けるようにすることができる。 In addition, when the frame display 125 disappears step by step with gradation, the display is divided into a contact effective region and a contact invalid region with a boundary where the display density is, for example, 50% as a boundary. Can do.
　また、額縁表示を、近接時には色を変更、通信可能時には消去するなどとしてそれぞれの状態を区別できるようにしても良い。 Also, the frame display may be distinguished from each other by changing the color when close and deleting it when communication is possible.
　このようにして表示装置２００ａ、２００ｂの近接部分の額縁表示を消去することにより、複数の表示装置があたかも一つの大きな表示装置になったかのようにユーザに感じさせることに加え、両表示装置間でデータを送る際の障壁が消えたようにユーザに感じさせることができる。また、近接している部分にのみ額縁表示を行うことで、再び表示装置を引き離すために把持し直す場合に、誤操作を引き起こすことのない領域を分かりやすくすることができる。 In this way, by deleting the frame display of the adjacent portions of the display devices 200a and 200b, in addition to making the user feel as if the plurality of display devices have become one large display device, between the display devices. Users can feel as if the barrier to sending data has disappeared. In addition, by displaying the frame only on the adjacent portion, it is possible to make it easy to understand a region that does not cause an erroneous operation when the display device is gripped again to separate it.
　一方で、表示装置２００ａと表示装置２００ｂが離れ、ステップＳ２０１において、近接センサ１２０が相手の表示装置の近接を検出できなくなると、近接通信を切断し（ステップＳ２１２、Ｓ２１３）、切断が完了したら額縁表示消去領域１３０に額縁表示を行うようにする（ステップＳ２１４）。 On the other hand, if the display device 200a and the display device 200b are separated and the proximity sensor 120 cannot detect the proximity of the partner display device in step S201, the proximity communication is disconnected (steps S212 and S213). Frame display is performed in the display erasure area 130 (step S214).
　ここでさらに、図１３のフローチャートを用いて、額縁表示消去領域が変化した場合に、表示装置２００ａ、２００ｂがどのように近接しているかを判断する方法を説明する。 Here, a method of determining how close the display devices 200a and 200b are when the frame display erasure area changes will be described using the flowchart of FIG.
　ステップＳ２２０において、額縁表示消去領域が新たに出現した場合や、その形に変化があった場合は、ステップＳ２２１において、両表示装置間で、自己の表示装置の形状の情報と、自己の表示装置の額縁表示消去領域１３０の形状の情報と、近接が検知されたときの時刻という三種類の情報からなる近接情報を互いに送りあう。この送られてきた近接情報のうち、表示装置の形状の情報と、額縁表示消去領域１３０の形状の情報を用いることで、ステップＳ２２２において、相手の表示装置がどのような形で近接しているかを決定することができる。 In step S220, when a frame display erasure area newly appears or when its shape has changed, in step S221, information on the shape of its own display device and its own display device are displayed between both display devices. Proximity information consisting of three types of information, that is, the shape information of the frame display erasure area 130 and the time when the proximity is detected is sent to each other. Of the sent proximity information, the information on the shape of the display device and the information on the shape of the frame display erasure area 130 are used to determine in what form the display device of the other party is close in step S222. Can be determined.
　ただし、二つの表示装置が重なりのない状態から、図１４（Ａ）のように、重なっている状態へと変化したことが判明した場合（ステップＳ２２３、Ｓ２２４）、どちらの表示装置が重なりの上側であるかまでは、近接センサ１２０からの情報だけでは分からない。そこでその場合は、両表示装置において、重なり領域２１７に例えば「ここをタッチ」というメッセージを表示し（ステップＳ２２５、図１４（Ｂ））、重なり領域２１７がタッチされた側を表側（上側、表示面が隠されていない側）であるとすることで、両端末の上下関係を判断することができる（ステップＳ２２６、Ｓ２２７）。 However, when it is determined that the two display devices have changed from a state where there is no overlap to a state where they overlap as shown in FIG. 14A (steps S223 and S224), which display device is the upper side of the overlap. Is not known only from the information from the proximity sensor 120. In this case, for example, a message “touch here” is displayed in the overlapping area 217 in both display devices (step S225, FIG. 14B), and the side on which the overlapping area 217 is touched is displayed on the front side (upper, display). By assuming that the side is not concealed, the vertical relationship between both terminals can be determined (steps S226 and S227).
　このようにして二つの表示装置がどのような形で近接しているかを判断することにより、図１４（Ｃ）のように、両端末の境界にあたる場所に転送領域２１９（表示装置２００ａにおいては転送領域２１９ａ、表示装置２００ｂにおいては転送領域２１９ｂ）を設定することができる。なお、この転送領域２１９は、隣接する場合の両表示装置、および重なる場合の上側の表示装置においては、額縁表示消去領域１３０と一致する。 In this way, by determining how the two display devices are close to each other, as shown in FIG. 14C, a transfer area 219 (transfer in the display device 200a) is placed at a location corresponding to the boundary between both terminals. In the area 219a and the display device 200b, the transfer area 219b) can be set. The transfer area 219 coincides with the frame display erasure area 130 in both the display devices adjacent to each other and the upper display device in the case of overlapping.
　また、三つ以上の表示装置が近接する場合のうち、図１５（Ａ）～（Ｃ）に示したように、ステップ２２８において、表示装置２００ａの複数の額縁表示消去領域１３０ａのうち、少なくとも二つの形が同じであると判断される場合は、どちらの表示装置がどちらの額縁表示消去領域１３０ａに近接しているかということを近接センサ１２０からの情報だけでは判断することはできない。この場合、ステップＳ２２９において、ステップＳ２２１で送信された近接情報のうち、近接が検知されたときの時刻の情報を用いることで、表示装置とその近接位置を対応付けることができる（ステップＳ２３１）。 Further, among the cases where three or more display devices are close to each other, as shown in FIGS. 15A to 15C, in step 228, at least two of the plurality of frame display erase regions 130a of the display device 200a. When it is determined that the two shapes are the same, it cannot be determined by the information from the proximity sensor 120 which display device is adjacent to which frame display erasure area 130a. In this case, in step S229, it is possible to associate the display device with its proximity position by using the time information when proximity is detected among the proximity information transmitted in step S221 (step S231).
　一方、ステップＳ２２９において、表示装置２００ａに表示装置２００ｂと２００ｃが同時もしくは短い時間差で近接したために近接の時刻から判別できない場合は、一度いずれかの端末を引き離して近接し直すように図１５（Ｃ２）のようなメッセージを表示したり、表示装置２００ａがスピーカを備えている場合には、図１５（Ｃ３）のように音声等で促したりすることで（ステップＳ２３０）、再び近接しなおした時刻から表示装置を判別することができる（ステップＳ２３１）。 On the other hand, in step S229, when the display devices 200b and 200c are close to the display device 200a simultaneously or with a short time difference and cannot be discriminated from the close time, one of the terminals is once pulled apart and close again as shown in FIG. ), Or when the display device 200a has a speaker, it is urged by voice or the like as shown in FIG. 15C3 (step S230), and the time when it approaches again. From this, the display device can be determined (step S231).
　次に、図１６のシーケンス図および図１７を用いて、表示装置２００ａから表示装置２００ｂにオブジェクトのアイコンをドラッグ（指などを接触させたまま移動すること）によって転送する方法を説明する。 Next, a method of transferring an object icon from the display device 200a to the display device 200b by dragging (moving while keeping a finger or the like in contact) will be described with reference to the sequence diagram of FIG. 16 and FIG.
　なお、ここでいうオブジェクトとは、画像ファイルや文書ファイルなどのデータそのものを表し、そのオブジェクトのアイコンに対して移動や消去などの操作を行うことによって、データの移動や消去を行うことができる。 Note that the object here represents data itself such as an image file or a document file, and data can be moved or deleted by performing an operation such as moving or deleting the icon of the object.
　初期状態における主表示領域１２７（接触有効領域）内には、図１７（Ａ）にようにドラッグが可能なオブジェクトのアイコン２２０ａが表示されている。 In the main display area 127 (contact effective area) in the initial state, an icon 220a of a draggable object is displayed as shown in FIG.
　表示装置２００ａが表示装置２００ｂの上に重なるように近接して額縁表示の少なくとも一部が消去されているとき、表示装置２００ａに表示されているアイコン２２０ａをドラッグして少なくともその一部が転送領域２１９ａに含まれるように移動させると（ステップＳ２５０、図１７（Ｂ））、このオブジェクトの名前や種類などからなる基本情報に加え、アイコン２２０ａの位置情報が表示装置２００ｂに送られ（ステップＳ２５１、Ｓ２６０）、表示装置２００ｂ上の転送領域２１９ｂに、送られてきたオブジェクトの基本情報とアイコンの位置情報に基づいて、アイコン２２０ｂを半透明の状態で表示する（ステップＳ２６１、図１７（Ｃ））。 When at least a part of the frame display is erased so that the display device 200a overlaps with the display device 200b, the icon 220a displayed on the display device 200a is dragged and at least a part of the display is transferred. When moved so as to be included in 219a (step S250, FIG. 17B), in addition to the basic information including the name and type of the object, the position information of the icon 220a is sent to the display device 200b (step S251, In step S260, the icon 220b is displayed in a translucent state on the transfer area 219b on the display device 200b based on the received basic information of the object and the position information of the icon (step S261, FIG. 17C). .
　そして、ステップＳ２６２において、表示装置２００ｂの画面上においてアイコン２２０ｂを転送領域２１９ｂの外にドラッグすると（図１７（Ｄ））、そのオブジェクトのデータの転送要求が表示装置２００ａに送られ（ステップＳ２６３、Ｓ２５２）、それに応じて表示装置２００ａから表示装置２００ｂにデータ転送が開始される（ステップＳ２５３）。 In step S262, when the icon 220b is dragged out of the transfer area 219b on the screen of the display device 200b (FIG. 17D), a data transfer request for the object is sent to the display device 200a (step S263, In response to this, data transfer is started from the display device 200a to the display device 200b (step S253).
　そして転送が完了すると（ステップＳ２６４）、転送が完了したことが表示装置２００ａに通知され（ステップＳ２６５、Ｓ２５４）、表示装置２００ａ上のアイコン２２０ａおよびオブジェクトのデータが消去される（ステップＳ２５５）。一方で、表示装置２００ｂ上のアイコン２２０ｂは半透明状態を解除されて濃く表示される（ステップＳ２６６、図１７（Ｅ））。このようにして、表示装置間でのドラッグを直感的に行うことが可能となる。 When the transfer is completed (step S264), the display device 200a is notified that the transfer is completed (steps S265 and S254), and the icon 220a and the object data on the display device 200a are deleted (step S255). On the other hand, the icon 220b on the display device 200b is released from the semi-transparent state and displayed darkly (step S266, FIG. 17E). In this way, it is possible to intuitively drag between display devices.
　以上の形態により、本実施例２では、実施例１に記載したような様々な近接の場合において、額縁表示の変更およびデータ転送を実現することが可能となる。 With the above configuration, in the second embodiment, it is possible to change the frame display and transfer data in various proximity cases as described in the first embodiment.
　なお、上記の表示装置間でのドラッグは表示装置間でカット＆ペーストを行うことに相当するが、表示装置２００ｂにおいて半透明のアイコン２２０ｂを転送領域２１９ｂから引き離す（アイコン２２０ａを表示装置２００ａから２００ｂに移動させる）際（ステップＳ２６２）に、表示装置２００ａにおけるアイコン２２０ａが例えばもう一本の指などによって接触が行われている場合は、アイコン２２０ａを表示した状態を維持し、表示装置２００ａからオブジェクトのデータを消去しないようにして、表示装置間でのコピー＆ペーストに相当するものを実現するようにしても良い。 Note that dragging between the display devices corresponds to cutting and pasting between the display devices, but the translucent icon 220b is pulled away from the transfer area 219b on the display device 200b (the icon 220a is moved from the display devices 200a to 200b). When the icon 220a on the display device 200a is in contact with, for example, another finger at the time of moving to (step S262), the state where the icon 220a is displayed is maintained, and the object from the display device 200a is maintained. The data corresponding to copying and pasting between display devices may be realized without erasing the data.
　また、アイコン２２０ａを転送領域２１９ａに向けて弾く（素早くドラッグしながら指を離す）操作を行ったときに転送が行われるようにしても良い。この場合、弾かれたアイコン２２０ａは速度を少しずつ落としながらそのまま軌道上を動き続け、所定の速度以上で転送領域２１９ａに到達した場合には、連続的な移動に見えるように、その速度および軌道を計算して、表示装置２００ｂの画面上にアイコン２２０ｂを表示する。 Alternatively, the transfer may be performed when an operation of flipping the icon 220a toward the transfer area 219a (swiping the finger while releasing it) is performed. In this case, the bounced icon 220a continues to move on the orbit while gradually reducing the speed. When the icon 220a reaches the transfer area 219a at a predetermined speed or more, the speed and the orbit are seen so as to appear to move continuously. And the icon 220b is displayed on the screen of the display device 200b.
　本発明によれば、表示装置同士の位置関係に応じて額縁表示を変更することで、単体で利用するときと複数を近接させて利用するときの両方において使いやすい表示装置を提供することができる。 According to the present invention, by changing the frame display according to the positional relationship between the display devices, it is possible to provide a display device that is easy to use both when used alone and when used in close proximity. .
