Description
本発明は、タッチパネルに接続されたコンピュータに組み込まれる入力インタフェースに関する。より具体的には、基本のキーボード画像を左右に分けた場合の各部分に相当する一対のキーボード画像をタッチパネルの画面の左手位置と右手位置とに表示し、各キーボード画像に対する操作を共に有効な操作として受け付ける入力インタフェース、およびこの入力インタフェースが導入された文字入力装置ならびに情報処理装置に関する。
The present invention relates to an input interface incorporated in a computer connected to a touch panel. More specifically, a pair of keyboard images corresponding to each part when the basic keyboard image is divided into left and right are displayed at the left hand position and the right hand position on the screen of the touch panel, and operations on each keyboard image are both effective. The present invention relates to an input interface that is accepted as an operation, and a character input device and an information processing device in which the input interface is introduced.
タッチパネルを有する携帯型の情報処理装置の中に、タッチパネル内で所定のジェスチャが検出されたことに応じて1つのキーボード画像を左右一対のキーボード画像に分割し、左のキーボード画像を画面の左手位置に表示し、右のキーボード画像を画面の右手位置に表示する機能(以下、「キーボード分割機能」という。)を有するものがある(たとえば特許文献1を参照。)。このキーボード分割機能は、タッチパネルが設けられた筐体をユーザが両手で持って双方の親指でタッチを行う場合など、両手の手指による操作が行われる場合を想定して導入されたものである。
In a portable information processing apparatus having a touch panel, one keyboard image is divided into a pair of left and right keyboard images in response to detection of a predetermined gesture within the touch panel, and the left keyboard image is positioned on the left hand of the screen. And has a function of displaying the right keyboard image at the right hand position of the screen (hereinafter referred to as “keyboard dividing function”) (see, for example, Patent Document 1). This keyboard division function is introduced on the assumption that an operation is performed with the fingers of both hands, such as when the user holds the casing provided with the touch panel with both hands and touches with both thumbs.
また特許文献1には、元のキーボード画像を幅中央部で単純に二分する方法のほか、分割位置の近傍のキーを分割後の各キーボード画像に共通に含めることが記載されている。
Further, Patent Document 1 describes that the original keyboard image is simply divided into two at the center of the width, and that the keys near the division position are included in each divided keyboard image in common.
しかしながら、従来のキーボード分割機能は、システム設計者により定められた条件に従ってキーボード画像を分割するだけであり、その分割により表示されたキーボード画像のキーの配列状態がユーザの癖や入力シーンの実情に合うとは限らない。このため、ユーザによっては、操作がしづらくなるおそれがある。
本発明は上記の問題に着目し、ユーザの実際の操作状況に応じて左右のキーボード画像の形態を変動させることによって、操作の利便性を向上し、入力作業を効率良く進行できるようにすることを課題とする。 However, the conventional keyboard division function only divides the keyboard image according to the conditions determined by the system designer, and the keyboard layout of the keyboard image displayed by the division depends on the situation of the user's habit and input scene. It doesn't always fit. For this reason, it may be difficult for some users to perform the operation.
The present invention pays attention to the above-mentioned problem, and improves the convenience of the operation and allows the input work to proceed efficiently by changing the form of the left and right keyboard images according to the actual operation situation of the user. Is an issue.

It doesn't always fit. For this reason, it may be difficult for some users to perform the operation.
The present invention pays attention to the above-mentioned problem, and improves the convenience of the operation and allows the input work to proceed efficiently by changing the form of the left and right keyboard images according to the actual operation situation of the user. Is an issue.
本発明によるプログラムは、タッチパネルに接続されたコンピュータに、基本のキーボード画像をその一部分を重複させて左右に分けた場合の各部分に相当する一対のキーボード画像をタッチパネルの画面の左手位置と右手位置とに分けて表示する表示実行手段と、前記一対のキーボード画像のそれぞれに対する操作を有効として受け付ける受付手段とを具備する入力インタフェースの機能を設定するものである。
The program according to the present invention provides a computer connected to a touch panel with a pair of keyboard images corresponding to each part when a basic keyboard image is overlapped and divided into left and right positions on the touch panel screen. A function of an input interface comprising: a display execution means for separately displaying and an accepting means for accepting an operation for each of the pair of keyboard images as valid.
この入力インタフェースの表示実行手段は、各キーボード画像の他方のキーボード画像の側の端縁に面する位置にそれぞれ他方のキーボード画像にも含まれるキーを重複させて配置すると共に、各キーボード画像の間で重複するキーに対する操作に関して、一方のキーボード画像の他方のキーボード画像の側の端縁に面する位置に設けられたキーに対する操作頻度が所定の閾値を上回ったことに応じて、前者のキーボード画像が後者のキーボード画像の側に向かって拡張し、後者のキーボード画像が前者のキーボード画像の側から後退する方向に向かって縮小するように、各キーボード画像のキーの数および各キーボード画像の間におけるキーの重複関係を変化させる。
The display execution means of this input interface arranges the keys included in the other keyboard image in an overlapping manner at positions facing the edge of the other keyboard image side of each keyboard image, and between the keyboard images. In regard to the operation on the overlapping keys in the first keyboard image, the operation frequency for the key provided at the position facing the edge of the other keyboard image side of one keyboard image exceeds a predetermined threshold value. Between the number of keys in each keyboard image and between each keyboard image so that the latter expands towards the latter keyboard image and the latter keyboard image shrinks away from the former keyboard image. Change the key overlap.
上記の表示処理によれば、左右一対のキーボード画像の境界付近にあっていずれのキーボード画像に含めるかの判断が困難なキーを、双方のキーボード画像に含めておくことにより、これら重複したキーに対する操作をいずれのキーボード画像でも行うことができる。また、各キーボード画像の間で重複するキーのうち、画面の左手に表示されるキーボード画像において右端に配置されるキーに対する操作頻度が所定の閾値を上回った場合には、左のキーボード画像のキーの数が増えて当該キーボード画像が右側に向かって拡張する一方、右のキーボード画像ではキーの数が減って当該キーボード画像が右方向に向かって縮小する。反対に、右のキーボード画像において左端に配置されるキーに対する操作頻度が閾値を上回った場合には、右のキーボード画像のキーの数が増えて当該キーボード画像が左側に向かって拡張する一方、左のキーボード画像ではキーの数が減って当該キーボード画像が左方向に向かって縮小する。
According to the above display processing, by including keys that are near the boundary between the pair of left and right keyboard images and are difficult to determine which keyboard image to include in both keyboard images, The operation can be performed with any keyboard image. If the operation frequency for the key arranged at the right end in the keyboard image displayed on the left hand of the screen among keys overlapping between the keyboard images exceeds a predetermined threshold, the key of the left keyboard image The number of keys increases and the keyboard image expands toward the right side, while in the right keyboard image, the number of keys decreases and the keyboard image decreases toward the right. On the other hand, when the operation frequency for the key arranged at the left end in the right keyboard image exceeds the threshold, the number of keys in the right keyboard image increases and the keyboard image expands toward the left side, while the left In the keyboard image, the number of keys is reduced and the keyboard image is reduced in the left direction.
上記のとおり、左右のキーボード画像の間で重複するキーに対する操作に関して、一方のキーボード画像の端縁に配置されているキーが使用される頻度が高い場合には、このよく使われるキーを含むキーボード画像のキーが増え、他方のキーボード画像のキーが減り、その変化に応じて各キーボード画像の間におけるキーの重複関係も変動する。この処理を繰り返すことによって、重複部分に対する操作によく使用される方のキーボード画像のキーの数を増やして、操作性を高めることができる。
As described above, when the keys arranged on the edge of one keyboard image are frequently used for the operation on the key overlapping between the left and right keyboard images, the keyboard including the frequently used key is used. The number of keys in the image increases, the number of keys in the other keyboard image decreases, and the overlapping relationship of the keys between the keyboard images also changes in accordance with the change. By repeating this process, it is possible to increase the number of keys of the keyboard image that is often used for the operation on the overlapped portion, thereby improving the operability.

図4に示したキーボード10L,10Rの形態の変化は、左右のキーボード10L,10Rの間で重複している8個のキーのうち、右キーボード10Rの左端の半透明領域100Rに含まれている4個のキー(「T」「G」「V」の各文字キーおよび左矢印キー)に対する操作について、右キーボード10Lが使用される頻度が左キーボード10Rが使用される頻度を上回ったことによるものである。
The change in the form of the keyboards 10L and 10R shown in FIG. 4 is included in the translucent region 100R at the left end of the right keyboard 10R among the eight keys overlapping between the left and right keyboards 10L and 10R. Regarding the operation for the four keys (character keys “T”, “G”, “V” and the left arrow key), the frequency with which the right keyboard 10L is used exceeds the frequency with which the left keyboard 10R is used. It is.
図3および図4の例は、左右のキーボード10L,10Rの半透明領域100R,100Rに対する操作頻度をキーボード10L,10R毎に計数して、その計数値に基づき各行のキーの個数を同様に増減させるものである。これに対し、つぎの図5の例では、各半透明領域100L,100Rに対する操作頻度をキーボード毎および行毎に計数することによって、キーボード10L,10Rのキーの個数を行単位で変更する。
In the example of FIG. 3 and FIG. 4, the operation frequency for the translucent areas 100R and 100R of the left and right keyboards 10L and 10R is counted for each of the keyboards 10L and 10R, and the number of keys in each row is similarly increased or decreased based on the counted value. It is something to be made. On the other hand, in the following example of FIG. 5, the number of keys of the keyboards 10L and 10R is changed in units of rows by counting the operation frequency for the translucent areas 100L and 100R for each keyboard and each row.
図5の上段と下段との間で、各キーボード10L,10Rの上から2行目のキー配列を比較すると、上段の初期の左キーボード10Lでは左キーボード10Lのみに含まれていた「F」の文字キーが、下段では右キーボード10Rの左端に加えられている。一方、初期の左キーボード10Lの右端に配置されていた「H」の文字キーは、下段では左キーボード10Lから消失して右キーボード10Rのみに含まれる状態になる。すなわち、上から2行目のキー配列では、右キーボード10Rのキーが1つ増え、左キーボード10Lのキーが1つ減っている。
When comparing the keyboard layout of the second row from the top of each keyboard 10L, 10R between the upper and lower stages of FIG. 5, in the initial left keyboard 10L in the upper stage, the “F” included only in the left keyboard 10L. A character key is added to the left end of the right keyboard 10R in the lower row. On the other hand, the character key “H” arranged at the right end of the initial left keyboard 10L disappears from the left keyboard 10L and is included only in the right keyboard 10R in the lower stage. That is, in the key arrangement in the second row from the top, the key of the right keyboard 10R is increased by one and the key of the left keyboard 10L is decreased by one.
図5の上段と下段との間で、各キーボード10L,10Rの上から3行目のキー配列を比較すると、上段の初期の右キーボード10Rでは右キーボード10Rのみに含まれていた「N」の文字キーが、下段では左キーボード10Lの右端に加えられている。一方、初期の右キーボード10Rの左端に配置されていた「V」の文字キーは、下段では右キーボード10Rから消失して左キーボード10Lのみに含まれる状態になる。すなわち、上から3行目のキー配列では、左キーボード10Lのキーが1つ増え、右キーボード10Rのキーが1つ減っている。
Comparing the keyboard layout of the third row from the top of each keyboard 10L, 10R between the upper and lower stages in FIG. 5, the initial right keyboard 10R in the upper stage is “N” included only in the right keyboard 10R. A character key is added to the right end of the left keyboard 10L in the lower row. On the other hand, the character key “V” arranged at the left end of the initial right keyboard 10R disappears from the right keyboard 10R and is included only in the left keyboard 10L in the lower row. That is, in the key arrangement in the third row from the top, the number of the left keyboard 10L is increased by one, and the number of the right keyboard 10R is decreased by one.
上から2行目のキー配列の変化は、この行に関して各キーボード10L,10Rの間で重複している「G」のキーに対する操作において、右キーボード10Rの半透明領域100Rが使用される頻度が左キーボード10Lが使用される頻度を上回ったことによるものである。上から3行目のキー配列の変化は、この行に関して各キーボード10L,10Rの間で重複している「B」のキーに対する操作において、左キーボード10Lの半透明領域100Lが使用される頻度が右キーボード10Rが使用される頻度を上回ったことによるものである。これらに対し、図5の最上段および最下段のキー配列では、重複部分に対する左右のキーボード10L,10Rでの操作頻度に大きな差が生じていないため、各キー配列は初期状態のまま維持されている。
The change in the key arrangement on the second line from the top indicates that the translucent area 100R of the right keyboard 10R is used in the operation on the “G” key overlapping between the keyboards 10L and 10R with respect to this line. This is because the frequency with which the left keyboard 10L is used is exceeded. The change in the key arrangement on the third line from the top indicates that the frequency of using the translucent area 100L of the left keyboard 10L is used in the operation on the “B” key overlapping between the keyboards 10L and 10R with respect to this line. This is because the frequency with which the right keyboard 10R is used is exceeded. On the other hand, in the uppermost and lowermost key arrangements in FIG. 5, there is no significant difference in the operation frequency of the left and right keyboards 10L and 10R with respect to the overlapped portion, so that each key arrangement is maintained in the initial state. Yes.
図6は、文字の入力操作に応じて文字入力処理部15により入力候補の文字列が抽出されたことに伴って、各キーボード10L,10Rに候補表示欄18L,18Rが設定された場合の表示の例を示す。これらの候補表示欄18L,18Rは、基本キーボード画像10に含まれた候補表示欄の一部を有効領域に設定するキーボード表示制御部13の処理と、この設定を受けた各キーボード表示部11,12の処理とによって表示されたもので、基本キーボード画像中の候補表示欄の所定範囲が各候補表示欄18L,18Rに共通に含まれている。

Specifically, in this embodiment, the semi-transparent display ranges in the candidate display fields 18L and 18R of the keyboards 10L and 10R correspond to the semi-transparent display ranges in the key arrangement on the first line. The contents of the candidate display combining the left and right candidate display fields 18L and 18R are the same as in FIGS. 6A and 6B, but the breakdown of the candidates included in the translucent areas 100L and 100R in each example is different. It has become.
なお、図6(2)の候補表示欄18L内の「ワイン」のように、候補表示欄18L,18Rの半透明表示の範囲に候補の全体が含まれない場合もあるが、そのような不完全な表示に対してタッチ操作が行われた場合でも、その操作は有効な操作として受け付けられる。
キーボード10L,10Rの形態を行毎に変化させる図5の実施例において候補表示欄18L,18Rが表示される場合には、候補表示欄18L,18Rについても、キー配列から独立させて幅を変動させることができる。たとえば、各キーボード10L,10Rの半透明領域100L,100Rに含まれる候補の選択について、一方のキーボードの半透明領域に対する操作頻度が他方のキーボードの対応箇所に対する操作頻度を上回ったときに、この半透明領域を含む候補表示欄の幅を所定長さ分だけ延長し、その延長分に相当する長さだけ他方の候補表示欄の幅を短くすることができる。 Note that there may be cases where the entire candidate is not included in the semi-transparent display range of thecandidate display fields 18L and 18R, such as “wine” in the candidate display field 18L of FIG. 6B. Even when a touch operation is performed on a complete display, the operation is accepted as an effective operation.
When thecandidate display fields 18L and 18R are displayed in the embodiment of FIG. 5 in which the form of the keyboards 10L and 10R is changed for each line, the widths of the candidate display fields 18L and 18R are also varied independently of the key arrangement. Can be made. For example, when selecting the candidates included in the translucent areas 100L and 100R of the keyboards 10L and 10R, when the operation frequency for the translucent area of one keyboard exceeds the operation frequency for the corresponding part of the other keyboard, this half is selected. The width of the candidate display field including the transparent area can be extended by a predetermined length, and the width of the other candidate display field can be shortened by a length corresponding to the extension.
キーボード10L,10Rの形態を行毎に変化させる図5の実施例において候補表示欄18L,18Rが表示される場合には、候補表示欄18L,18Rについても、キー配列から独立させて幅を変動させることができる。たとえば、各キーボード10L,10Rの半透明領域100L,100Rに含まれる候補の選択について、一方のキーボードの半透明領域に対する操作頻度が他方のキーボードの対応箇所に対する操作頻度を上回ったときに、この半透明領域を含む候補表示欄の幅を所定長さ分だけ延長し、その延長分に相当する長さだけ他方の候補表示欄の幅を短くすることができる。 Note that there may be cases where the entire candidate is not included in the semi-transparent display range of the
When the
上記のとおり、図3~図6に示した実施例では、左キーボード10Lと右キーボード10Rとの間で、それぞれの他方のキーボード10R,10Lに対向する側の端縁に面する4個のキーとそれらの隣に配置される4個のキーとを重複させ、端縁に面する4個のキーを半透明状態に設定した。また、これら半透明のキーに対する操作頻度が閾値を上回ったことに応じて各キーボード10L,10Rの形態を変化させた。ただし、半透明表示の対象範囲は上記に限定されるものではなく、各キーボード10L,10Rの間で重複する全てのキーを含む範囲を半透明領域10L,10Rとし、そのうち他方のキーボードの側の端縁に面するキーに対する操作頻度に基づき、上記の各実施例と同様の方法で各キーボード10L,10Rの形態を変化させてもよい。
As described above, in the embodiment shown in FIGS. 3 to 6, four keys facing the edge on the side facing the other keyboards 10R and 10L between the left keyboard 10L and the right keyboard 10R. And four keys arranged next to them were overlapped, and the four keys facing the edge were set in a translucent state. In addition, the form of each of the keyboards 10L and 10R was changed in response to the operation frequency for these translucent keys exceeding a threshold value. However, the target range of the semi-transparent display is not limited to the above, and the range including all the keys overlapping between the keyboards 10L and 10R is set as the semi-transparent region 10L and 10R, of which the other keyboard side is located. The form of each keyboard 10L, 10R may be changed in the same manner as in each of the above embodiments based on the operation frequency for the keys facing the edge.
また、図7に示すように、各キーボード10L,10Rの間で行毎で重複させるキーを1個ずつにすることにより、各半透明領域100L,100Rに含まれるキーを一致させてもよい。
図7は、各キーボード10L,10Rの間で重複するキーに対する操作において、左キーボード10Lの半透明領域100Lが使用される頻度が右キーボード10Rの半透明領域100Rが使用される頻度を上回った場合の各キーボード10L,10Rの形態の変化を示すものである。この場合、右キーボード10Rの左端の半透明領域100Rに配置されていた4個のキー(「T」「G」「V」の各文字キーおよび左矢印キー)が右キーボード10Rから消去され、これら消去されたキーの隣に配置されていた4個のキー((「Y」「H」「B」の各文字キーおよび右矢印キー)が左キーボード10Lの右端に加えられる。右キーボード10Rの左端にも、左キーボード10Lに新たに加えられた4個のキーが配置されるので、各キーボード10L,10Rの半透明領域100L,100Rの整合状態が維持される。 In addition, as shown in FIG. 7, the keys included in the translucent areas 100L and 100R may be matched by using one key for each row between the keyboards 10L and 10R.
FIG. 7 shows a case where the frequency of using thetranslucent area 100L of the left keyboard 10L exceeds the frequency of using the translucent area 100R of the right keyboard 10R in an operation on a key overlapping between the keyboards 10L and 10R. The change of the form of each keyboard 10L, 10R is shown. In this case, the four keys (“T”, “G”, “V” character keys and the left arrow key) arranged in the leftmost translucent region 100R of the right keyboard 10R are erased from the right keyboard 10R. Four keys (("Y", "H", "B" character keys and right arrow key) arranged next to the erased key are added to the right end of the left keyboard 10L. The left end of the right keyboard 10R In addition, since the four newly added keys are arranged on the left keyboard 10L, the alignment state of the translucent areas 100L and 100R of the keyboards 10L and 10R is maintained.
図7は、各キーボード10L,10Rの間で重複するキーに対する操作において、左キーボード10Lの半透明領域100Lが使用される頻度が右キーボード10Rの半透明領域100Rが使用される頻度を上回った場合の各キーボード10L,10Rの形態の変化を示すものである。この場合、右キーボード10Rの左端の半透明領域100Rに配置されていた4個のキー(「T」「G」「V」の各文字キーおよび左矢印キー)が右キーボード10Rから消去され、これら消去されたキーの隣に配置されていた4個のキー((「Y」「H」「B」の各文字キーおよび右矢印キー)が左キーボード10Lの右端に加えられる。右キーボード10Rの左端にも、左キーボード10Lに新たに加えられた4個のキーが配置されるので、各キーボード10L,10Rの半透明領域100L,100Rの整合状態が維持される。 In addition, as shown in FIG. 7, the keys included in the
FIG. 7 shows a case where the frequency of using the
上記とは逆に、図7に示した右キーボード10Rの半透明領域100Rに対する操作頻度が左キーボード10Lの半透明領域100Lに対する操作頻度を上回った場合には、左キーボード10Lの右端の半透明領域100Lに配置されていた4個のキーが左キーボード10Lから消去され、これら消去されたキーの隣に配置されていた4個のキー(たとえば「R」「F」「C」の各文字キーおよび「変換」キー)が右キーボード10Rに加えられる。この変更後の左キーボード10Lの右端にも、右キーボード10Rに新たに加えられた4個のキーが配置されるので、各キーボード10L,10Rの半透明領域100L,100Rの整合状態が維持される。
On the contrary, when the operation frequency for the semi-transparent area 100R of the right keyboard 10R shown in FIG. 7 exceeds the operation frequency for the semi-transparent area 100L of the left keyboard 10L, the translucent area at the right end of the left keyboard 10L. The four keys arranged at 100L are erased from the left keyboard 10L, and the four keys arranged next to these erased keys (for example, the character keys “R”, “F”, “C”, and the like) A “conversion” key) is added to the right keyboard 10R. Since the four keys newly added to the right keyboard 10R are also arranged at the right end of the left keyboard 10L after the change, the alignment state of the translucent areas 100L and 100R of the keyboards 10L and 10R is maintained. .
図7の例の左キーボード10Lおよび右キーボード10Rについても、それぞれの間の重複部分に対する操作頻度を行毎に判別して、図5の例と同様に、行単位でキー配列の拡張や縮小を行うことができる。候補表示欄18R,18Lが表示される場合についても、図6の例と同様に、候補表示欄18R,18Lを含むキーボード10L,10Rの全体を対象として、操作頻度の判別やキーボード10L,10Rの形態の変更を行うことができる。
As for the left keyboard 10L and the right keyboard 10R in the example of FIG. 7, the operation frequency for the overlapping portion between each is determined for each line, and the key arrangement is expanded or reduced in units of lines as in the example of FIG. It can be carried out. Also in the case where the candidate display fields 18R and 18L are displayed, as in the example of FIG. 6, the operation frequency is determined and the keyboards 10L and 10R are determined for the entire keyboard 10L and 10R including the candidate display fields 18R and 18L. The form can be changed.
各キーボード10L,10Rにおける半透明領域100L,100Rの設定は、上記に示した例に限らず、各キーボード10L,10Rの間で重複しているキー群を対象に、適宜、各行のキー配列の構成やキーの数に応じて変更することができる。また半透明領域100L,100Rに含めるキーの数を行によって異なる数にしてもよい。
図8は、図3および図4に示した方式で各キーボード10L,10Rの形態を変化させる場合の処理の手順を示すものである。この処理は、アプリケーション3の画面で文字入力を指示するタップ操作などが行われたことに応じて、キーボード表示制御部13が左キーボード表示部11および右キーボード表示部12と協働して実行するものである。なお、この処理と並列して文字入力処理部15による処理も進行するが、こちらの処理の流れは従来と同様であるので、説明を省略する。 The setting of the translucent areas 100L and 100R in the keyboards 10L and 10R is not limited to the example described above, and the key arrangement of each row is appropriately set for a key group overlapping between the keyboards 10L and 10R. It can be changed according to the configuration and the number of keys. The number of keys included in the translucent areas 100L and 100R may be different depending on the row.
FIG. 8 shows a processing procedure when the form of each of the keyboards 10L and 10R is changed by the method shown in FIGS. This processing is executed by the keyboard display control unit 13 in cooperation with the left keyboard display unit 11 and the right keyboard display unit 12 in response to a tap operation for instructing character input on the screen of the application 3. Is. In addition, although the process by the character input process part 15 also advances in parallel with this process, since the flow of this process is the same as the past, description is abbreviate | omitted.
図8は、図3および図4に示した方式で各キーボード10L,10Rの形態を変化させる場合の処理の手順を示すものである。この処理は、アプリケーション3の画面で文字入力を指示するタップ操作などが行われたことに応じて、キーボード表示制御部13が左キーボード表示部11および右キーボード表示部12と協働して実行するものである。なお、この処理と並列して文字入力処理部15による処理も進行するが、こちらの処理の流れは従来と同様であるので、説明を省略する。 The setting of the

最初のステップS1では、一段階前に実行されたキーボード表示処理での設定情報に基づき、左キーボード10Lおよび右キーボード10Rを表示する。この設定情報は操作検出部14により文字入力の終了を指示する操作が検出されてステップS9が「YES」となった場合に、終了前のステップS10で保存されるものである。図8では、ステップS10で保存される情報として、各キーボード10L,10Rの有効領域や半透明領域100L,100Rを表す設定情報が記載されているが、これらのほか、左右のキーボード10L,10R毎の操作頻度を表す数値データNL,NR(以下「操作頻度データ」という。)も、次の段階の処理に引き継ぐために保存される。
In the first step S1, the left keyboard 10L and the right keyboard 10R are displayed based on the setting information in the keyboard display process executed one stage before. This setting information is stored in step S10 before the end when the operation detecting unit 14 detects an operation for instructing the end of the character input and “YES” in step S9. In FIG. 8, setting information representing the effective areas and translucent areas 100L and 100R of the keyboards 10L and 10R is described as information stored in step S10. Numerical data NL and NR (hereinafter referred to as “operation frequency data”) representing the operation frequency of the above are also stored for the subsequent processing.
キーボード10L,10Rが表示された後は、左キーボード10Lまたは右キーボード10Rに対して何らかの操作が検出され(ステップS2が「YES」)、それが半透明領域100L,100Rに対する操作であった場合(ステップS3が「YES」)に、操作頻度データNL,NRの更新処理が実行される。
具体的には、左キーボード10Lの半透明領域100Lに対する操作が行われた場合には、左キーボード10Lの操作頻度データNLを現在値に1を加えた値に更新し、右キーボード10Rの操作頻度データNRを現在値から1を減じた値に更新する(ステップS5)。右キーボード10Rの半透明領域100Rに対する操作が行われた場合には、上記とは逆に、右キーボード10Rの操作頻度データNRを現在値に1を加えた値に更新し、左キーボード10Lの操作頻度データNLを現在値から1を減じた値に更新する(ステップS6)。 After the keyboards 10L and 10R are displayed, some operation is detected on the left keyboard 10L or the right keyboard 10R (“YES” in step S2), and this is an operation on the translucent areas 100L and 100R ( In step S3 “YES”), the operation frequency data NL and NR are updated.
Specifically, when an operation is performed on thetranslucent region 100L of the left keyboard 10L, the operation frequency data NL of the left keyboard 10L is updated to a value obtained by adding 1 to the current value, and the operation frequency of the right keyboard 10R is updated. The data NR is updated to a value obtained by subtracting 1 from the current value (step S5). When an operation is performed on the translucent area 100R of the right keyboard 10R, the operation frequency data NR of the right keyboard 10R is updated to a value obtained by adding 1 to the current value and the operation of the left keyboard 10L is reversed. The frequency data NL is updated to a value obtained by subtracting 1 from the current value (step S6).
具体的には、左キーボード10Lの半透明領域100Lに対する操作が行われた場合には、左キーボード10Lの操作頻度データNLを現在値に1を加えた値に更新し、右キーボード10Rの操作頻度データNRを現在値から1を減じた値に更新する(ステップS5)。右キーボード10Rの半透明領域100Rに対する操作が行われた場合には、上記とは逆に、右キーボード10Rの操作頻度データNRを現在値に1を加えた値に更新し、左キーボード10Lの操作頻度データNLを現在値から1を減じた値に更新する(ステップS6)。 After the
Specifically, when an operation is performed on the
上記のとおり、この実施例では、半透明領域100Lまたは100Rに対する操作が検出される都度、操作された半透明領域に対応する操作頻度データの値を加算する一方で操作されなかった半透明領域に対応する操作頻度データの値を減算するので、半透明領域100L,100Rに対する操作に関して各キーボード10L,10Rが用いられる頻度に偏りがある場合には、NLとNRとの間に大きな差が生じる。これに対し、半透明領域100L,100Rに対する通算の操作回数が増えても、左キーボード10Lが使用された頻度と右キーボード10Rが使用された頻度との差が小さい場合には、NL,NRの間の差も小さく、またいずれの頻度データも大きくならない。
As described above, in this embodiment, each time an operation on the semi-transparent area 100L or 100R is detected, the value of the operation frequency data corresponding to the operated semi-transparent area is added, while the non-operated semi-transparent area is added. Since the value of the corresponding operation frequency data is subtracted, if there is a bias in the frequency with which the keyboards 10L and 10R are used for operations on the semi-transparent areas 100L and 100R, a large difference occurs between NL and NR. On the other hand, when the total number of operations for the translucent areas 100L and 100R increases, if the difference between the frequency with which the left keyboard 10L is used and the frequency with which the right keyboard 10R is used is small, NL and NR The difference between them is small, and neither frequency data is large.
上記のステップS5またはS6の後は、更新された操作頻度データNL,NRのうちの値が高い方をあらかじめ定めた閾値と比較し、NLまたはNRが閾値を超えている場合(ステップS7が「YES」)にキーボード設定変更処理(ステップS8)を実行する。上記した操作頻度データNL,NRの特性によれば、左右のキーボード10L,10Rの間で半透明領域に対する操作に偏りが生じており、かつ半透明領域が多く操作されている方のキーボードに対応する操作頻度が閾値を上回った場合に、キーボード設定変更処理が行われることになる。よって、閾値の値を十分に大きくすることにより、ユーザが各キーボード10L,10Rの半透明領域10L,10Rのいずれか一方を好んで使用している場合に、キーボード設定変更処理が行われるようにすることができる。
After the above step S5 or S6, the higher one of the updated operation frequency data NL and NR is compared with a predetermined threshold value, and when NL or NR exceeds the threshold value (step S7 is “ YES ”), the keyboard setting changing process (step S8) is executed. According to the characteristics of the operation frequency data NL and NR described above, there is a bias in the operation with respect to the translucent area between the left and right keyboards 10L and 10R, and it corresponds to the keyboard in which many translucent areas are operated. When the operation frequency to be performed exceeds the threshold value, the keyboard setting change process is performed. Therefore, by increasing the threshold value sufficiently, the keyboard setting changing process is performed when the user prefers to use one of the translucent areas 10L and 10R of the keyboards 10L and 10R. can do.
図9は、キーボード設定変更処理(ステップS8)の詳細な手順を示すものである。この処理では、最初に、各キーボード10L,10Rに適用されている有効領域が変更可能な範囲にあるかどうかがチェックされる(ステップS11)。たとえば、幅が狭い方の有効領域の一行分のキーの数をあらかじめ登録された最小値(たとえば2個)と比較し、前者が後者より多い場合には有効領域は変更可能な範囲にあると判断される。
FIG. 9 shows the detailed procedure of the keyboard setting change process (step S8). In this process, first, it is checked whether or not the effective area applied to each of the keyboards 10L and 10R is within a changeable range (step S11). For example, the number of keys for one line of the narrower effective area is compared with a minimum value (for example, two) registered in advance. If the former is larger than the latter, the effective area is within a changeable range. To be judged.
上記の判断によりステップS11が「YES」となると、つぎのステップS12で操作頻度データNLとNRとの大小関係がチェックされる。ここでNL<NR、すなわち右キーボード10Rの半透明領域100Rに対する操作頻度が左キーボード10Lの半透明領域100Lに対する操作頻度を上回っている場合には、右キーボード10Rの有効領域をキー1つ分拡張し(ステップS13)、左キーボード10Lの有効領域をキー1つ分縮小する(ステップS14)。拡張や縮小の具体的な方法は図4の例に示したとおりである。
If step S11 becomes “YES” by the above determination, the magnitude relationship between the operation frequency data NL and NR is checked in the next step S12. If NL <NR, that is, if the operation frequency for the translucent area 100R of the right keyboard 10R exceeds the operation frequency for the translucent area 100L of the left keyboard 10L, the effective area of the right keyboard 10R is expanded by one key. Then, the effective area of the left keyboard 10L is reduced by one key (step S14). A specific method of expansion or reduction is as shown in the example of FIG.
上記とは逆に、NL>NR、すなわち左キーボード10Lの半透明領域100Lに対する操作頻度が右キーボード10Rの半透明領域100Rに対する操作頻度を上回っている場合には、左キーボード10Lの有効領域をキー1つ分拡張し(ステップS15)、右キーボード10Rの有効領域をキー1つ分縮小する(ステップS16)。拡張や収縮の具体的な方法は図3の例に示したとおりである。
On the contrary, when NL> NR, that is, when the operation frequency for the semi-transparent area 100L of the left keyboard 10L exceeds the operation frequency for the semi-transparent area 100R of the right keyboard 10R, the effective area of the left keyboard 10L is designated as a key. One is expanded (step S15), and the effective area of the right keyboard 10R is reduced by one key (step S16). The specific method of expansion and contraction is as shown in the example of FIG.
上記いずれかの手順によりキーボード10L,10Rの形態が変更されると、その変更後の左キーボード10Lの各行の右端のキーと、右キーボード19Rの各行の左端のキーとを、それぞれ半透明状態に設定する(ステップS17)。この後、操作頻度データNL,NRをリセットして、処理を終了する。
図5の例のように、各キーボード10L,10Rの形態を行毎に変動させる場合には、図7のステップS3~S8の手順を行毎に実行すればよい(ステップS8では図8のステップS11~S18を実行する。)。 When the form of the keyboard 10L, 10R is changed by any of the above procedures, the rightmost key of each row of the left keyboard 10L after the change and the leftmost key of each row of the right keyboard 19R are made translucent. Set (step S17). Thereafter, the operation frequency data NL and NR are reset, and the process ends.
When the form of each of the keyboards 10L and 10R is changed for each row as in the example of FIG. 5, the procedure of steps S3 to S8 in FIG. 7 may be executed for each row (in step S8, the steps of FIG. (S11 to S18 are executed.)
図5の例のように、各キーボード10L,10Rの形態を行毎に変動させる場合には、図7のステップS3~S8の手順を行毎に実行すればよい(ステップS8では図8のステップS11~S18を実行する。)。 When the form of the
When the form of each of the
なお、上記で説明した各実施例では、各キーボード10L,10Rの幅方向におけるキーの数を1個ずつ増減する方法で各キーボード10L,10Rの形態を変化させたが、キーの増減の単位はこれに限定されるものではない。たとえば、キーボード設定変更処理の実施の条件とする閾値の値を高めにして、毎回のキーボード設定変更処理において、各キーボード10L,10Rの幅を、キー2つ分ずつ拡張または縮小させてもよい。または、毎回のキーボード設定変更処理において各キーボード10L,10Rの幅をキー半個分ずつ拡張または縮小させる代わりに、キーボード設定変更処理が生じやすくなるように閾値の値を低めに設定してもよい。
In each of the embodiments described above, the form of each keyboard 10L, 10R is changed by increasing or decreasing the number of keys in the width direction of each keyboard 10L, 10R one by one. It is not limited to this. For example, by increasing the threshold value as a condition for executing the keyboard setting change process, the width of each keyboard 10L, 10R may be expanded or reduced by two keys in each keyboard setting change process. Alternatively, instead of expanding or reducing the width of each keyboard 10L, 10R by half a key in each keyboard setting change process, the threshold value may be set low so that the keyboard setting change process is likely to occur. .
タッチパネルにおける各キーボード10L,10Rの表示位置は、左キーボード10Lを左側に表示し、右キーボード10Rを右側に表示するというルールを守ることを前提に、事前の設定やユーザのドラッグ操作などに応じて変更することができる。特に、高さ位置に関しては、左キーボード10Lと右キーボード10Rとを合わせる必要はなく、それぞれの位置を自由に変更することができる。
The display positions of the keyboards 10L and 10R on the touch panel are based on prior settings, user drag operations, and the like on the assumption that the left keyboard 10L is displayed on the left side and the right keyboard 10R is displayed on the right side. Can be changed. In particular, regarding the height position, it is not necessary to match the left keyboard 10L and the right keyboard 10R, and the respective positions can be freely changed.
上記の実施例に示した入力インタフェースによれば、たとえば、情報処理装置であるタブレット型の端末装置をユーザが両手で持って親指で各キーボード10L,10Rを操作する場合や、端末装置を利き手でない方の手で支持しながら、利き手側の指により主要な操作を行い、支持側の手の指で補助的な操作を行う場合などに、各キーボード10L,10Rをユーザにとって操作しやすい形態に変化させることができる。
According to the input interface shown in the above embodiment, for example, when a user holds a tablet-type terminal device, which is an information processing device, with both hands and operates the keyboards 10L and 10R with the thumb, or the terminal device is not a dominant hand. The keyboard 10L, 10R is changed to a form that is easy for the user to operate, for example, when the main hand is operated with the dominant hand and the auxiliary hand is operated with the supporting hand. Can be made.
