FIG. 1 is a block diagram showing an information input display apparatus according to the first embodiment. As shown in FIG. 1, the information input display device according to the first embodiment includes a touch panel 101, a contact position detection unit 103, a contact size measurement unit 105, a control unit 107, and a key selection unit 109. The control unit 107 includes a candidate key selection unit 111 and a display control unit 113.
　タッチパネル１０１は、液晶パネル等の表示部と、情報入力表示装置のユーザの指やスタイラス等の外部操作手段によって接触又は押圧された領域（以下「接触領域」という。）を示す信号を外部に出力する位置入力部とが組み合わされて構成されている。 The touch panel 101 outputs a signal indicating an area (hereinafter referred to as a “contact area”) touched or pressed by a display unit such as a liquid crystal panel and an external operation means such as a finger of the user of the information input display device or a stylus. And a position input unit.
　接触位置検出部１０３は、タッチパネル１０１から出力された信号に基づいて、タッチパネル１０１上の外部操作手段による接触位置を検出する。なお、接触位置検出部１０３は、タッチパネル１０１から送られた信号が示す接触領域の中心点を外部操作手段による接触位置として検出する。接触位置検出部１０３によって検出された接触位置を示す信号は、制御部１０７の候補キー選択部１１１に送られる。 The contact position detection unit 103 detects the contact position by the external operation unit on the touch panel 101 based on the signal output from the touch panel 101. The touch position detection unit 103 detects the center point of the touch area indicated by the signal transmitted from the touch panel 101 as a touch position by the external operation unit. A signal indicating the touch position detected by the touch position detection unit 103 is sent to the candidate key selection unit 111 of the control unit 107.
　接触サイズ測定部１０５は、タッチパネル１０１から出力された信号に基づいて、外部操作手段によるタッチパネル１０１上の接触領域の縦及び横の各長さを測定する。なお、接触領域の縦及び横の各長さは、タッチパネル１０１から出力された信号から作成された図２に示す格子状のデータに基づいて測定される。接触サイズ測定部１０５によって測定された接触領域の縦及び横の各長さを示す信号は、制御部１０７の表示制御部１１３に送られる。 The contact size measurement unit 105 measures the vertical and horizontal lengths of the contact area on the touch panel 101 by the external operation unit based on the signal output from the touch panel 101. The vertical and horizontal lengths of the contact area are measured based on grid-like data shown in FIG. 2 generated from the signal output from the touch panel 101. A signal indicating the vertical and horizontal lengths of the contact area measured by the contact size measurement unit 105 is sent to the display control unit 113 of the control unit 107.
　制御部１０７の候補キー選択部１１１は、タッチパネル１０１に表示された仮想キー（以下、単に「キー」という。）の内、接触位置検出部１０３が検出した接触位置を中心とした円状の所定の領域に含まれるキーを候補キーとして選択する。なお、所定の領域は、円状に限らず矩形状であっても良い。また、制御部１０７の表示制御部１１３は、接触サイズ測定部１０５によって測定された接触領域の縦の長さと同じ縦方向の間隔をあけ、かつ、接触領域の横の長さと同じ横方向の間隔をあけて、候補キーを表示するようタッチパネル１０１を制御する。 Among the virtual keys (hereinafter, simply referred to as “keys”) displayed on the touch panel 101, the candidate key selection unit 111 of the control unit 107 has a predetermined circular shape centered on the touch position detected by the touch position detection unit 103. The key included in the area of is selected as a candidate key. The predetermined area is not limited to a circular shape, and may be a rectangular shape. In addition, the display control unit 113 of the control unit 107 opens a space in the same longitudinal direction as the vertical length of the contact area measured by the contact size measurement unit 105, and a horizontal space in the same direction as the lateral length of the contact area. , And controls the touch panel 101 to display candidate keys.
　図３及び図４は、タッチパネル１０１に表示された複数のキーの内、左上のキー付近が指で触れられた場合のタッチパネル１０１の表示例を示す図である。図３（ａ）に示すように、タッチパネル１０１に表示された複数のキーの内、左上のキー付近が指で触れられた場合、タッチパネル１０１からは斜線で表された接触領域を示す信号が接触位置検出部１０３及び接触サイズ測定部１０５に送られる。 FIGS. 3 and 4 are diagrams showing display examples of the touch panel 101 when the vicinity of the upper left key among the plurality of keys displayed on the touch panel 101 is touched with a finger. As shown in FIG. 3A, when the vicinity of the upper left key among the plurality of keys displayed on the touch panel 101 is touched with a finger, the touch panel 101 makes contact with a signal indicating a contact area represented by oblique lines. It is sent to the position detection unit 103 and the contact size measurement unit 105.
　接触位置検出部１０３は、図３（ａ）に黒丸で示された接触領域の中心点を接触位置として検出する。候補キー選択部１１１は、この接触位置を中心とした図３（ａ）に点線で表された円状の領域１５１に完全に含まれるキー「Ａ」、「Ｂ」、「Ｄ」、「Ｅ」を候補キーとして選択する。なお、候補キー選択部１１１は、少なくとも一部が領域１５１に重なるキー（キー「Ａ」、「Ｂ」、「Ｃ」、「Ｄ」、「Ｅ」、「Ｆ」、「Ｇ」、「Ｈ」、「Ｉ」）を候補キーとして選択しても良い。接触サイズ測定部１０５は、図３（ｂ）に斜線で示された接触領域の縦の長さＡ及び横の長さＢを測定する。表示制御部１１３は、縦方向に長さＡと同じ間隔をあけ、かつ、横方向に長さＢと同じ間隔をあけて、４つの候補キーを表示するようタッチパネル１０１を制御する。 The contact position detection unit 103 detects, as a contact position, the central point of the contact area indicated by a black circle in FIG. The candidate key selection unit 111 selects the keys “A”, “B”, “D”, and “E” completely included in the circular area 151 represented by the dotted line in FIG. Is selected as a candidate key. Note that the candidate key selection unit 111 is a key (keys “A”, “B”, “C”, “D”, “E”, “F”, “G”, “H”) at least a part of which overlaps the area 151. "," "I") may be selected as candidate keys. The contact size measurement unit 105 measures the vertical length A and the horizontal length B of the contact area indicated by hatching in FIG. 3B. The display control unit 113 controls the touch panel 101 to display four candidate keys at intervals equal to the length A in the vertical direction and at intervals equal to the length B in the lateral direction.
　なお、図４に示した場合も、表示制御部１１３は、縦方向に接触領域の縦の長さＣと同じ間隔をあけ、かつ、横方向に接触領域の横の長さＤと同じ間隔をあけて、４つの候補キー「Ａ」、「Ｂ」、「Ｄ」、「Ｅ」を表示するようタッチパネル１０１を制御する。なお、本実施形態では、表示制御部１１３は、候補キーの大きさは変更せずに間隔のみを上述のようにあける。 Also in the case shown in FIG. 4, the display control unit 113 has the same interval as the longitudinal length C of the contact area in the vertical direction, and the same interval as the lateral length D of the contact area in the lateral direction. The touch panel 101 is controlled to display four candidate keys "A", "B", "D", and "E". Note that, in the present embodiment, the display control unit 113 leaves only the intervals as described above without changing the sizes of the candidate keys.
　キー選択部１０９は、外部操作手段によるタッチパネル１０１との接触状態から非接触状態となったとき、非接触状態となる直前に外部操作手段が接触していた候補キーを入力キーとして確定する。キー選択部１０９によって入力キーが確定されると、確定信号がキー選択部１０９から制御部１０７の表示制御部１１３に送られる。表示制御部１１３は、当該確定信号を受け取ると、上述の間隔をあけた候補キーの表示状態から間隔をあけない元の表示状態に戻すようタッチパネル１０１を制御する。 When the non-contact state is entered from the contact state with the touch panel 101 by the external operation means, the key selection portion 109 determines the candidate key touched by the external operation means immediately before the non-contact state as the input key. When the key selection unit 109 determines the input key, a confirmation signal is sent from the key selection unit 109 to the display control unit 113 of the control unit 107. When the display control unit 113 receives the confirmation signal, the display control unit 113 controls the touch panel 101 to return from the display state of the above-mentioned spaced candidate keys to the original display state where there is no spacing.
　図５は、第１の実施形態の情報入力表示装置の動作を示すフローチャートである。図５に示すように、まず、ステップＳ１０１では、タッチパネル１０１が、外部操作手段による接触を判断し、接触があった場合は接触領域を示す信号を出力してステップＳ１０３に進む。ステップＳ１０３では、接触位置検出部１０３が、タッチパネル１０１上の外部操作手段による接触位置を検出する。次に、ステップＳ１０５では、候補キー選択部１１１が、タッチパネル１０１に表示されたキーの内、接触位置を中心とした円状の所定の領域に含まれるキーを候補キーとして選択する。 FIG. 5 is a flow chart showing the operation of the information input display apparatus of the first embodiment. As shown in FIG. 5, first, in step S101, the touch panel 101 determines a touch by the external operation unit, and when there is a touch, a signal indicating a touch area is output, and the process proceeds to step S103. In step S <b> 103, the touch position detection unit 103 detects a touch position by the external operation unit on the touch panel 101. Next, in step S105, the candidate key selection unit 111 selects, from among the keys displayed on the touch panel 101, a key included in a predetermined circular area centered on the touch position as a candidate key.
　次に、ステップＳ１０７では、接触サイズ測定部１０５が、外部操作手段によるタッチパネル１０１上の接触領域の縦及び横の各長さを測定する。次に、ステップＳ１０９では、表示制御部１１３が、接触領域の縦の長さと同じ縦方向の間隔をあけ、かつ、接触領域の横の長さと同じ横方向の間隔をあけて、候補キーを表示するようタッチパネル１０１を制御する。次に、ステップＳ１１１では、タッチパネル１０１が、外部操作手段による接触の維持を判断し、接触状態が維持されている場合はステップＳ１０３に戻り、非接触状態のときはステップＳ１１３に進む。 Next, in step S107, the contact size measurement unit 105 measures the vertical and horizontal lengths of the contact area on the touch panel 101 by the external operation unit. Next, in step S109, the display control unit 113 displays candidate keys at intervals in the vertical direction equal to the vertical length of the contact area and at intervals in the horizontal direction equal to the horizontal length of the contact area. The touch panel 101 is controlled to do so. Next, in step S111, the touch panel 101 determines whether or not the touch by the external operation means is maintained. If the touch state is maintained, the process returns to step S103. If the touch state is the non-touch state, the process proceeds to step S113.
　ステップＳ１１３では、キー選択部１０９が、タッチパネル１０１が非接触状態となる直前に外部操作手段が接触していた候補キーを入力キーとして確定する。次に、ステップＳ１１５では、表示制御部１１３が、ステップＳ１０９による間隔をあけた候補キーの表示状態から間隔をあけない元の表示状態に戻すようタッチパネル１０１を制御する。 In step S113, the key selection unit 109 determines, as an input key, a candidate key touched by the external operation means immediately before the touch panel 101 is brought into the non-contact state. Next, in step S115, the display control unit 113 controls the touch panel 101 to return from the display state of the candidate keys spaced apart in step S109 to the original display state not spaced apart.
　以上説明したように、第１の実施形態の情報入力表示装置によれば、外部操作手段によるタッチパネル１０１上の接触位置近傍の候補キーが、接触領域の縦及び横の各長さと同じ縦方向及び横方向の間隔をあけて表示される。このように、候補キー間に外部操作手段による接触領域のサイズに相当する間隔が設けられた状態で当該候補キーがタッチパネル１０１に表示されるため、外部操作手段による接触は１つの候補キーに限定される。この結果、キー選択部１０９は、情報入力表示装置のユーザが意図するキーを確実に入力キーとして選択する。したがって、高い精度で誤入力を防止できる。 As described above, according to the information input display device of the first embodiment, the candidate keys in the vicinity of the touch position on the touch panel 101 by the external operation means have the same vertical direction as the vertical and horizontal lengths of the touch area and Displayed with horizontal space. Thus, since the candidate key is displayed on the touch panel 101 in a state where an interval corresponding to the size of the touch area by the external operation means is provided between the candidate keys, the contact by the external operation means is limited to one candidate key Be done. As a result, the key selection unit 109 reliably selects a key intended by the user of the information input display device as an input key. Therefore, erroneous input can be prevented with high accuracy.
　また、本実施形態では、外部操作手段によるタッチパネル１０１上の接触位置近傍に表示された一部の仮想キーのみが候補キーとして上記形態で表示されるため、タッチパネル１０１の限られた表示領域内に上記間隔が設けられた候補キーを表示できる。 Further, in the present embodiment, only a part of virtual keys displayed in the vicinity of the touch position on the touch panel 101 by the external operation means is displayed as the candidate key in the above-described form. The candidate key provided with the above-mentioned interval can be displayed.
　さらに、本実施形態では、隣り合う候補キー間の間隔が外部操作手段による接触時に決定されるため、本実施形態の情報入力表示装置のユーザが変わっても、高い精度で誤入力を防止できる最適な間隔が候補キー間に設定される。 Furthermore, in the present embodiment, since the interval between adjacent candidate keys is determined at the time of touch by the external operation means, it is possible to prevent erroneous input with high accuracy even if the user of the information input display device of the present embodiment changes. Interval is set between candidate keys.
（第２の実施形態）
　図６は、第２の実施形態の情報入力表示装置を示すブロック図である。第２の実施形態の情報入力表示装置は、第１の実施形態の情報入力表示装置が備える構成要素に加えて、接触時間計測部２０１を備える。なお、本実施形態の表示制御部２１３は、接触時間計測部２０１から入力された信号に応じて、以下説明する動作をさらに行う。この点以外は第１の実施形態と同様であり、図６において、図１と共通する構成要素には同じ参照符号が付されている。 Second Embodiment

Except this point, the second embodiment is the same as the first embodiment. In FIG. 6, the same reference numerals as in FIG. 1 denote the same constituent elements in FIG.
　接触時間計測部２０１は、タッチパネル１０１から出力された信号に基づいて、外部操作手段によるタッチパネル１０１との連続接触時間を計測する。本実施形態の表示制御部２１３は、接触時間計測部２０１が計測した連続接触時間に応じて、候補キー選択部１１１によって選択された候補キーを拡大して表示するようタッチパネル１０１を制御する。 The contact time measurement unit 201 measures the continuous contact time with the touch panel 101 by the external operation unit based on the signal output from the touch panel 101. The display control unit 213 according to the present embodiment controls the touch panel 101 so that the candidate key selected by the candidate key selection unit 111 is enlarged according to the continuous contact time measured by the contact time measurement unit 201.
　図７及び図８は、タッチパネル１０１に表示された複数のキーの内、左上のキー付近が指で触れられ続けた場合のタッチパネル１０１の表示例を示す図である。図７（ａ）及び図８（ａ）に示すように、タッチパネル１０１に指が触れて候補キーが表示された直後の各候補キーの大きさは、縦の長さがＸ１、横の長さがＹ１の矩形である。その後、指がタッチパネル１０１の同位置に触れられ続けると、表示制御部２１３は、図７（ｂ）（ｃ）及び図８（ｂ）（ｃ）に示すように、連続接触時間に比例して、縦横比を維持したまま各候補キーを拡大して表示するようタッチパネル１０１を制御する。なお、各候補キーを拡大表示する際の最大値を設定しても良い。 FIGS. 7 and 8 are diagrams showing display examples of the touch panel 101 when the vicinity of the upper left key among the plurality of keys displayed on the touch panel 101 is continuously touched by a finger. As shown in FIGS. 7A and 8A, the size of each candidate key immediately after the finger touches the touch panel 101 and the candidate key is displayed has a vertical length of X1 and a horizontal length. Is a rectangle of Y1. Thereafter, when the finger continues to be touched at the same position on the touch panel 101, the display control unit 213, as shown in FIGS. 7 (b) and (c) and FIGS. 8 (b) and (c), is proportional to the continuous contact time. The touch panel 101 is controlled to expand and display each candidate key while maintaining the aspect ratio. In addition, you may set the maximum value at the time of enlarging and displaying each candidate key.
　図９は、第２の実施形態の情報入力表示装置の動作を示すフローチャートである。図９に示すように、第２の実施形態では、図５に示したフローチャート中のステップＳ１０１とステップＳ１０３の間で、ステップＳ２０１が行われる。ステップＳ２０１では、接触時間計測部２０１が、外部操作手段による連続接触時間の計測を開始する。 FIG. 9 is a flowchart showing the operation of the information input display device of the second embodiment. As shown in FIG. 9, in the second embodiment, step S201 is performed between step S101 and step S103 in the flowchart shown in FIG. In step S201, the contact time measurement unit 201 starts measuring the continuous contact time by the external operation unit.
　また、本実施形態では、図９に示すように、図５に示したフローチャート中のステップＳ１０９の代わりにステップＳ２０９が行われる。ステップＳ２０９では、表示制御部２１３が、接触領域の縦の長さと同じ縦方向の間隔をあけ、かつ、接触領域の横の長さと同じ横方向の間隔をあけて、連続接触時間に応じた大きさの候補キーを表示するようタッチパネル１０１を制御する。上記ステップＳ２０１，Ｓ２０９以外は図５に示した第１の実施形態の処理と同様である。 Further, in the present embodiment, as shown in FIG. 9, step S209 is performed instead of step S109 in the flowchart shown in FIG. In step S209, the display control unit 213 sets the vertical interval equal to the vertical length of the contact area and the horizontal interval equal to the horizontal length of the contact area, and the size according to the continuous contact time The touch panel 101 is controlled to display the candidate key of the size. The process other than the above steps S201 and S209 is the same as the process of the first embodiment shown in FIG.
　以上説明したように、第２の実施形態の情報入力表示装置によれば、外部操作手段によるタッチパネル１０１との連続接触時間が長くなるに従って、タッチパネル１０１には候補キーが拡大表示される。このため、情報入力表示装置のユーザは、意図するキーを確実に選択することができる。したがって、より高い精度で誤入力を防止できる。 As described above, according to the information input display device of the second embodiment, the candidate keys are enlarged and displayed on the touch panel 101 as the continuous contact time with the touch panel 101 by the external operation unit becomes longer. For this reason, the user of the information input display apparatus can reliably select the intended key. Therefore, erroneous input can be prevented with higher accuracy.

　第３の実施形態の情報入力表示装置によれば、接触領域の大きさに変化があっても、接触中はその縦横の最大値に応じた間隔で各候補キーがタッチパネルに表示される。したがって、情報入力表示装置のユーザは、タッチパネル１０１に対する外部操作手段による接触の強弱が発生するような状況であっても、意図するキーを確実に選択することができる。したがって、より高い精度で誤入力を防止できる。 According to the information input display device of the third embodiment, even if there is a change in the size of the touch area, each candidate key is displayed on the touch panel at an interval corresponding to the maximum value in the vertical and horizontal directions during the touch. Therefore, the user of the information input / display apparatus can reliably select the intended key even in a situation where the touch of the touch panel 101 by the external operation means occurs. Therefore, erroneous input can be prevented with higher accuracy.
