In the control device 4, processing associated with the selection icon 50 a is performed based on a selection operation of the selection icon 50 a described later by the user.

図３は、本実施形態の表示画面１０を示す平面図である。図３（ａ）は通常画面、図３（ｂ）は一部の選択アイコンが拡大表示された拡大表示画面を示している。図３に示すように、本実施形態の表示画面１０には、記号入力部５０、入力文字列表示部５１、確定アイコン５２、検索アイコン５３、修正アイコン５４、５５、中止アイコン５６が表示されている。   FIG. 3 is a plan view showing the display screen 10 of the present embodiment. FIG. 3A shows a normal screen, and FIG. 3B shows an enlarged display screen on which some selection icons are enlarged. As shown in FIG. 3, the display screen 10 of the present embodiment displays a symbol input unit 50, an input character string display unit 51, a confirmation icon 52, a search icon 53, correction icons 54 and 55, and a stop icon 56. Yes.

記号入力部５０は、通常の５０音表の様式で並べられた入力候補文字としての複数の文字アイコン５０ａから成る。これら文字アイコン５０ａは選択アイコンであり、ユーザの操作によってそれらのうちの１つが選択されることで、その選択された文字アイコン５０ａの示す文字が入力文字列表示部５１に追加される。例えば、ユーザが「あ」の選択アイコン５０ａを選択した場合は、入力文字列表示部５１に「あ」の文字を表示させる。   The symbol input unit 50 includes a plurality of character icons 50a as input candidate characters arranged in a normal 50-sound table format. These character icons 50 a are selection icons, and when one of them is selected by a user operation, the character indicated by the selected character icon 50 a is added to the input character string display unit 51. For example, when the user selects the selection icon 50 a for “A”, the character “A” is displayed on the input character string display unit 51.

確定アイコン５２は、記号入力部５０の周辺（図３（ａ）（ｂ）において右下）に配置され、ユーザがこのアイコンを押すことにより、地名の入力が完了し、このとき入力文字列表示部５１に表示されている文字列が目的地の名称となる。そして、検索アイコン５３を押すことにより、制御装置４はナビゲーションＥＣＵ６に入力された文字列を出力する。   The confirmation icon 52 is arranged in the vicinity of the symbol input unit 50 (lower right in FIGS. 3A and 3B), and when the user presses this icon, the place name input is completed. The character string displayed in the part 51 is the name of the destination. Then, when the search icon 53 is pressed, the control device 4 outputs the character string input to the navigation ECU 6.

修正アイコン５４、５５は、記号入力部５０の周辺（図３（ａ）（ｂ）において左下）に配置され、入力文字列表示部５１に表示される文字列のうち、ユーザが修正したい文字を選択することにより、ユーザが選択した文字が入力文字列表示部５１における表示から削除される。   The correction icons 54 and 55 are arranged around the symbol input unit 50 (lower left in FIGS. 3A and 3B), and the character that the user wants to correct among the character strings displayed on the input character string display unit 51 is displayed. By selecting, the character selected by the user is deleted from the display in the input character string display unit 51.

中止アイコン５６は、記号入力部５０の周辺（図３（ａ）（ｂ）において右上）に配置され、ユーザがこのアイコンを押すことにより、文字入力は強制的に終了し、この文字入力のための５０音入力画面を表示する前の画面の再表示を行う。   The stop icon 56 is arranged around the symbol input unit 50 (upper right in FIGS. 3A and 3B). When the user presses this icon, the character input is forcibly terminated. The screen before displaying the 50-sound input screen is redisplayed.

次に、図３を参照しながら、本実施形態における情報入力表示装置の拡大表示の表示例を説明する。ユーザが選択アイコン５０ａに指を近づけると、制御装置４は、赤外線スイッチ３によりアイコン選択物体の接近を検出し、表示画面１０の画面表示を、検出されたアイコン選択物体の位置近傍の選択アイコン５０ａを拡大表示する拡大表示画面に切り換える。拡大表示画面で拡大する範囲は任意に設定できるが、図３（ｂ）に示す例では、指を近づけた選択アイコン「て」を中心として１つ隣の選択アイコン５０ａまで拡大表示している。   Next, an enlarged display example of the information input display device according to the present embodiment will be described with reference to FIG. When the user brings a finger close to the selection icon 50a, the control device 4 detects the approach of the icon selection object by the infrared switch 3, and displays the screen display on the display screen 10 in the vicinity of the position of the detected icon selection object. Switch to the enlarged display screen that displays an enlarged image. The range to be enlarged can be arbitrarily set on the enlarged display screen, but in the example shown in FIG. 3B, the selection icon “te” with a finger close to the center is enlarged to the next selection icon 50a.

そして、選択アイコン５０ａが拡大表示された状態で、指をタッチスイッチ２に対して平行に移動させると、選択アイコン５０ａが拡大表示される領域も指とともに移動する。ユーザは、拡大表示画面において、希望する選択アイコン５０ａの位置まで指をずらし、選択アイコン５０ａを選択することができる。また、選択アイコン５０ａから指を遠ざけると、拡大表示画面から通常画面に戻る。   Then, when the finger is moved in parallel with the touch switch 2 in a state where the selection icon 50a is displayed in an enlarged manner, the area where the selection icon 50a is displayed in an enlarged manner also moves with the finger. The user can select the selection icon 50a by moving his / her finger to the position of the desired selection icon 50a on the enlarged display screen. When the finger is moved away from the selection icon 50a, the enlarged display screen returns to the normal screen.

次に、図４を参照しながら、本実施形態における情報入力表示装置の処理動作について説明する。図４は、本実施形態における情報入力表示装置の制御装置４のＣＰＵがＲＯＭに格納されたプログラムに従って行う処理内容を示すフローチャートである。   Next, the processing operation of the information input display device in this embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing the processing contents performed by the CPU of the control device 4 of the information input display device according to the present embodiment in accordance with a program stored in the ROM.

まず、赤外線スイッチ３によって、手や指などのアイコン選択物体のタッチスイッチ２への接近が検出されたか否かを判定する（Ｓ１００）。この結果、アイコン選択物体のタッチスイッチ２への接近が検出されなかった場合は（Ｓ１００：ＮＯ）、通常画面を表示し（Ｓ１１０）、ステップＳ１００に戻る。一方、アイコン選択物体の表示画面１０への接近が検出された場合は（Ｓ１００：ＹＥＳ）、ステップＳ１００において接近が検出されたアイコン選択物体の座標を計算する（Ｓ１２０）。   First, it is determined whether or not the infrared switch 3 detects that an icon selected object such as a hand or a finger has approached the touch switch 2 (S100). As a result, when the approach of the icon selected object to the touch switch 2 is not detected (S100: NO), the normal screen is displayed (S110), and the process returns to step S100. On the other hand, when the approach of the icon selected object to the display screen 10 is detected (S100: YES), the coordinates of the icon selected object for which the approach was detected in step S100 are calculated (S120).

次に、ステップＳ１２０において計算された座標近傍の選択アイコン５０ａを拡大して表示する拡大表示画面に切り換える（Ｓ１３０）。   Next, the screen is switched to an enlarged display screen for enlarging and displaying the selection icon 50a near the coordinates calculated in step S120 (S130).

次に、タッチスイッチ２が押下されたか否かを判定する（Ｓ１４０）。この結果、タッチスイッチ２が押下されなかった場合は（Ｓ１４０：ＮＯ）、ステップＳ１００に戻る。一方、タッチスイッチ２が押下された場合は（Ｓ１４０：ＹＥＳ）、タッチスイッチ２が押下された位置に基づいて、その位置に対応する選択アイコン５０ａに関連づけられた処理を行う（Ｓ１５０）。   Next, it is determined whether or not the touch switch 2 has been pressed (S140). As a result, when the touch switch 2 is not pressed (S140: NO), the process returns to step S100. On the other hand, when the touch switch 2 is pressed (S140: YES), processing associated with the selection icon 50a corresponding to the position is performed based on the position where the touch switch 2 is pressed (S150).

以上のように、ユーザが選択したい選択アイコン５０ａの近傍にアイコン選択物体を近づけるだけで、その付近の領域が拡大表示されるため、希望する選択アイコン５０ａを容易に選択操作することできる。これにより、選択アイコン５０ａが小さく表示されている場合であっても、選択アイコン５０ａの誤選択を防止することが可能となる。さらに、選択アイコン５０ａが拡大表示されているときにアイコン選択物体を移動させると、表示画面１０に拡大表示される領域も移動するため、選択操作をより容易にすることが可能となる。また、アイコン選択物体の接近を検出して自動的に拡大表示画面になり、アイコン選択物体が遠ざかると通常画面に戻るため、画面切り換え操作が不要となり、選択操作を容易にすることが可能となる。   As described above, the user can easily select and select the desired selection icon 50a because the area near the selected icon 50a can be enlarged just by bringing the icon selection object close to the selection icon 50a that the user wants to select. Thereby, even if the selection icon 50a is displayed in a small size, it is possible to prevent erroneous selection of the selection icon 50a. Furthermore, when the icon selection object is moved while the selection icon 50a is displayed in an enlarged manner, the area displayed on the display screen 10 is also moved, so that the selection operation can be facilitated. Further, when the approach of the icon selected object is detected, the screen automatically becomes an enlarged display screen, and when the icon selected object moves away, the screen returns to the normal screen, so that the screen switching operation is not required and the selection operation can be facilitated. .
