Description

携帯情報端末装置およびタッチパネルの感度設定方法Portable information terminal device and touch panel sensitivity setting method
　この発明は、タッチパネルを有する携帯情報端末装置、および、タッチパネルの感度設定方法に関する。 The present invention relates to a portable information terminal device having a touch panel and a sensitivity setting method for the touch panel.
　タッチパネルを有する携帯情報端末装置は、一般的に、タッチパネルに対する素手によるタッチを検出するように調整されており、手袋を装着した状態では上記タッチは検出されない。 A personal digital assistant having a touch panel is generally adjusted to detect a touch with a bare hand on the touch panel, and the touch is not detected when a glove is worn.
　そこで、手袋装着中でもタッチパネルに対するタッチ操作が可能なように、感度を上げることが考えられる。しかしながら、単純に感度を上げただけでは、素手で使用する場合に敏感になり過ぎて、指をタッチパネルに近づけただけでタッチと誤認識される等の誤動作の懸念がある。 Therefore, it is conceivable to increase the sensitivity so that the touch operation on the touch panel can be performed even while wearing gloves. However, simply increasing the sensitivity becomes too sensitive when used with bare hands, and there is a risk of malfunction such as being erroneously recognized as a touch simply by bringing a finger close to the touch panel.
　そこで、通常は素手によるタッチを前提としたモード(以下、「通常モード」と言う)で使用するが、ユーザー操作により感度を上げたモード(以下、「高感度モード」と言う)に切り替えることによって、手袋装着時でのタッチパネルに対するタッチ操作を可能にすることが一般的である。 Therefore, it is usually used in a mode that assumes touch with bare hands (hereinafter referred to as `` normal mode ''), but by switching to a mode with increased sensitivity by user operation (hereinafter referred to as `` high sensitivity mode '') Generally, it is possible to perform a touch operation on the touch panel when wearing gloves.
　ユーザーの利便性を考えて、上記高感度モード切替用の特別なスイッチを設けることなく、手袋を装着した状態で上記高感度モードに切り替えるためのユーザー操作が可能な方法として、特開２０１２‐１９４７９１号公報(特許文献１)に開示された携帯端末装置による方法がある。 In consideration of the convenience of the user, as a method capable of user operation for switching to the high sensitivity mode while wearing gloves without providing a special switch for switching the high sensitivity mode, Japanese Patent Application Laid-Open No. 2012-194791 There is a method using a mobile terminal device disclosed in Japanese Patent Publication (Patent Document 1).
　この特許文献１に開示された携帯端末装置においては、ユーザーからの入力の検出感度を設定可能なタッチパネルと、携帯端末装置本体の加速度を検出する加速度検出部と、この加速度検出部によって所定の加速度を超える加速度が検出された場合に、上記タッチパネルの上記検出感度を予め定められた感度に順次切り替えながらユーザーからの入力が検出可能か否かを判定し、この判定結果に基づいて上記タッチパネルの上記検出感度をユーザーからの入力を検出可能な感度に設定するようにしている。 In the mobile terminal device disclosed in Patent Document 1, a touch panel that can set the detection sensitivity of input from a user, an acceleration detection unit that detects acceleration of the mobile terminal device body, and a predetermined acceleration by the acceleration detection unit. Is detected, it is determined whether the input from the user can be detected while sequentially switching the detection sensitivity of the touch panel to a predetermined sensitivity, and based on the determination result, the touch panel The detection sensitivity is set to a sensitivity that can detect input from the user.
　しかしながら、上記従来の携帯端末装置においては、以下のような問題がある。すなわち、携帯端末装置本体の加速度とタッチパネルに対するタッチ動作とを検出するために、上記加速度検出部と上記タッチパネルのタッチセンサーとを常時動作させておく必要がある。したがって、消費電力が増加するという問題がある。特に、携帯端末装置の場合には電源を電池に頼るために、消費電力に拘わる問題は重要である。 However, the conventional mobile terminal device has the following problems. That is, in order to detect the acceleration of the mobile terminal device main body and the touch operation on the touch panel, it is necessary to always operate the acceleration detection unit and the touch sensor of the touch panel. Therefore, there is a problem that power consumption increases. In particular, in the case of a portable terminal device, since the power source depends on a battery, a problem related to power consumption is important.
　さらに、消費電力の低減を図るために、携帯端末装置本体に対する操作開始時のタッチパネルの画面であって、プライバシー保護のためのロック画面に限定して、上記加速度検出部と上記タッチセンサーとを動作させることが考えられる。しかしながら、その場合には、ロック解除を行う際に必ず携帯端末装置本体を振る操作が必要となり、使い勝手が悪くなってしまう。 Furthermore, in order to reduce power consumption, the acceleration detection unit and the touch sensor are operated only on the touch screen when the operation on the mobile terminal device starts, and only on the lock screen for privacy protection. It is possible to make it. However, in that case, it is necessary to shake the mobile terminal device body when unlocking, and the usability is deteriorated.

　以下、上記構成を有する携帯情報端末装置１による感度設定処理動作について詳細に説明する。 Hereinafter, the sensitivity setting processing operation by the portable information terminal device 1 having the above configuration will be described in detail.
　本実施の形態においては、タッチパネル２上に表示されるソフトウェアキー(以下、ソフトキーと言う)で成るロック解除ボタンに対するユーザーの操作を利用して感度設定処理を行うようにしている。すなわち、携帯情報端末装置１がロック状態であることを表すと共に、上記ロック解除ボタンが表示されているロック画面に関して、上記タッチセンサーの検出感度を段階的に上げながらユーザーの上記ロック解除ボタンに対するタッチを検出する。そして、上記ユーザーのタッチを検出した時点における上記検出感度に基づいて上記タッチセンサーの検出感度を本設定するのである。 In the present embodiment, the sensitivity setting process is performed by using the user's operation on the unlock button composed of software keys (hereinafter referred to as “soft keys”) displayed on the touch panel 2. That is, it represents that the portable information terminal device 1 is in a locked state, and the user touches the unlock button while gradually increasing the detection sensitivity of the touch sensor with respect to the lock screen on which the unlock button is displayed. Is detected. Then, the detection sensitivity of the touch sensor is set based on the detection sensitivity at the time when the user's touch is detected.
　図２は、上記制御処理部８による制御の下に実行される感度設定処理動作のフローチャートである。ユーザーによって電源ボタン６が押下されると、感度設定処理動作がスタートする。 FIG. 2 is a flowchart of sensitivity setting processing operation executed under the control of the control processing unit 8. When the power button 6 is pressed by the user, the sensitivity setting processing operation starts.
　ステップＳ1で、上記入出力制御部３によって、図３に例示するように、タッチパネル２にロック解除ボタン９を含む上記ロック画面が表示される。ステップＳ2で、感度調整部４によって、ロック画面用の上記タッチセンサーの検出感度(以下、単に検出感度と言う)が、「素手によるタッチを前提とした上記第１の感度である通常感度」に初期設定される。ここで、上記ロック画面の検出感度の初期値は、予め記憶部５に記憶されている。 In step S1, the input / output control unit 3 displays the lock screen including the lock release button 9 on the touch panel 2 as illustrated in FIG. In step S2, the sensitivity adjustment unit 4 causes the detection sensitivity of the touch sensor for the lock screen (hereinafter simply referred to as detection sensitivity) to be “normal sensitivity that is the first sensitivity on the premise of touch with bare hands”. Initially set. Here, the initial value of the detection sensitivity of the lock screen is stored in the storage unit 5 in advance.
　ユーザーは、上記ロック画面のロック解除ボタン９にタッチして下方向にスライドすることによってロック解除を行うことができる。 The user can unlock by touching the unlock button 9 on the lock screen and sliding downward.
　ステップＳ3で、上記入出力制御部３から入力される、タッチパネル２の上記タッチセンサーがユーザーによるタッチを検出したことを表すタッチ検出信号に基づいて、上記ロック画面表示後Ｎ秒以内に、ユーザーによるロック解除操作が検知されたか否かが判別される。その結果、ロック解除操作が検知された場合にはステップＳ9に進み、ロック解除操作が検知されない場合にはステップＳ4に進む。 In step S3, based on a touch detection signal that is input from the input / output control unit 3 and indicates that the touch sensor of the touch panel 2 has detected a touch by the user, within N seconds after the lock screen is displayed, It is determined whether an unlock operation has been detected. As a result, when the unlocking operation is detected, the process proceeds to step S9, and when the unlocking operation is not detected, the process proceeds to step S4.
　ステップＳ4で、上記ロック画面の検出感度が上記通常感度(初期設定)ではユーザーによるタッチを検出できないので、上記感度調整部４によって、記憶部５に記憶されたデータ情報に基づいて、上記ロック画面の検出感度が上記通常感度よりも高い上記第２の感度である高感度に設定される。 In step S4, since the touch sensitivity by the user cannot be detected when the detection sensitivity of the lock screen is the normal sensitivity (initial setting), the lock screen is detected based on the data information stored in the storage unit 5 by the sensitivity adjustment unit 4. Is set to high sensitivity which is the second sensitivity higher than the normal sensitivity.
　ステップＳ5で、上記ステップＳ3の場合と同様にして、上記高感度設定後Ｍ(Ｍ＞Ｎ)秒以内に、ユーザーによるロック解除操作が検知されたか否かが判別される。その結果、検知された場合にはステップＳ6に進み、検知されない場合にはステップＳ1にリターンして上記ロック画面の起動が行われる。 In step S5, in the same manner as in the case of step S3, it is determined whether or not an unlock operation by the user is detected within M (M> N) seconds after the high sensitivity setting. As a result, if detected, the process proceeds to step S6. If not detected, the process returns to step S1 to activate the lock screen.
　ステップＳ6で、ユーザーの意思を確認するために、問い合わせ文「高感度モードで起動しますか？」と、上記ソフトキーで成る「Yes」ボタンおよび「No」ボタンとを含む画面がポップアップ表示される。 In step S6, in order to confirm the user's intention, a pop-up screen including an inquiry sentence “Do you want to start in high sensitivity mode?” And the “Yes” button and “No” button consisting of the above soft keys is displayed. The
　ステップＳ7で、上記入出力制御部３から入力される上記タッチ検出信号に基づいて、上記ポップアップに対するユーザーの選択が「Yes」であるか否かが判別される。その結果、「Yes」である場合にはステップＳ8に進み、「Yes」ではない(「No」である)場合にはステップＳ9に進む。 In step S7, based on the touch detection signal input from the input / output control unit 3, it is determined whether or not the user's selection for the pop-up is “Yes”. As a result, if “Yes”, the process proceeds to step S8, and if not “Yes” (“No”), the process proceeds to step S9.
　ステップＳ8で、上記感度調整部４によって、制御処理部８からの指示に基づいて、タッチパネル２における上記位置入力デバイスの上記検出感度が高感度に設定される。こうして、タッチパネル２の上記表示デバイスに表示される総ての画面に対するタッチの検出感度が高感度に本設定されるのである。 In step S8, the sensitivity adjustment unit 4 sets the detection sensitivity of the position input device on the touch panel 2 to high sensitivity based on an instruction from the control processing unit 8. Thus, the touch detection sensitivity for all the screens displayed on the display device of the touch panel 2 is set to a high sensitivity.
　そうした後、上記感度設定処理動作が終了されて、ロック解除処理動作に移行する。 After that, the above sensitivity setting processing operation is terminated, and the process proceeds to the unlock processing operation.
　ステップＳ9で、上記感度調整部４によって、制御処理部８からの指示に基づいて、タッチパネル２における上記検出感度が通常感度に設定される。こうして、タッチパネル２の上記表示デバイスに表示される総ての画面に対するタッチの検出感度が通常感度に本設定される。 In step S9, the sensitivity adjustment unit 4 sets the detection sensitivity of the touch panel 2 to the normal sensitivity based on an instruction from the control processing unit 8. Thus, the touch detection sensitivity for all the screens displayed on the display device of the touch panel 2 is set to the normal sensitivity.
　そうした後、上記感度設定処理動作が終了されて、ロック解除処理動作に移行する。 After that, the above sensitivity setting processing operation is terminated, and the process proceeds to the unlock processing operation.
　以上のごとく、本実施の形態においては、ユーザーによって電源ボタン６が押下されると、タッチパネル２にロック解除ボタン９を含む上記ロック画面を表示し、上記ロック画面の検出感度を上記通常感度に初期設定する。そうした後、感度調整部４によって、上記ロック画面の検出感度をＮ秒間の「通常感度」とＭ秒間の「高感度」とを交互に切り替えながら、入出力制御部３からの上記タッチ検出信号に基づいて、ユーザーによるロック解除操作が検知されたか否かを判別する。 As described above, in the present embodiment, when the power button 6 is pressed by the user, the lock screen including the unlock button 9 is displayed on the touch panel 2, and the detection sensitivity of the lock screen is initially set to the normal sensitivity. Set. After that, the sensitivity adjustment unit 4 switches the detection sensitivity of the lock screen between the “normal sensitivity” for N seconds and the “high sensitivity” for M seconds, to the touch detection signal from the input / output control unit 3. Based on this, it is determined whether or not an unlock operation by the user has been detected.
　そして、上記ロック画面の検出感度が「通常感度」の際にロック解除操作が検知された場合には、感度調整部４によって、タッチパネル２に対する上記検出感度が通常感度に本設定される。これに対し、上記ロック画面の検出感度が「高感度」の際にロック解除操作が検知された場合には、高感度に本設定される。 If the unlocking operation is detected when the detection sensitivity of the lock screen is “normal sensitivity”, the sensitivity adjustment unit 4 sets the detection sensitivity for the touch panel 2 to the normal sensitivity. On the other hand, when the unlocking operation is detected when the detection sensitivity of the lock screen is “high sensitivity”, the high sensitivity is set.
　端的に言えば、手袋装着時にタッチ操作が可能なロック解除ボタン９を時間的に限定して設けることによって、ロック解除と検出感度設定とを同時に行うようにしている。 In short, the lock release button 9 that can be touch-operated when wearing gloves is provided for a limited time so that unlocking and detection sensitivity setting are performed simultaneously.
　したがって、抵抗値や静電容量の変化を検知することによって操作した手が手袋装着状態であるか否かを判断するためのメカニカルスイッチや、タッチパネル２の上記検出感度の切替要求のための振り動作を検出するための加速度センサ等の、特別なデバイスを設けることなく、手袋をした状態で上記検出感度を切り替えることができる。したがって、タッチパネル２の上記検出感度の切り替え時の利便性を高めることができる。 Therefore, a mechanical switch for determining whether or not the hand operated by detecting a change in resistance value or capacitance is in a glove wearing state, or a swinging operation for a request to switch the detection sensitivity of the touch panel 2 It is possible to switch the detection sensitivity in a gloved state without providing a special device such as an acceleration sensor for detecting the above. Therefore, convenience at the time of switching the detection sensitivity of the touch panel 2 can be enhanced.
　また、その際に、上記ロック画面におけるロック解除ボタン９に対するユーザーの操作を利用して感度設定処理を行うようにしている。したがって、タッチパネル２の検出感度切替用の専用の回路を追加設置したり、特別な処理を追加実行したりする必要がなく、消費電力の増加を抑制することができるのである。 Also, at that time, the sensitivity setting process is performed using the user's operation on the unlock button 9 on the lock screen. Therefore, it is not necessary to additionally install a dedicated circuit for switching the detection sensitivity of the touch panel 2 or to additionally execute special processing, and an increase in power consumption can be suppressed.
　尚、上記構成においては、素手による操作時において、何らかの理由によって上記ロック画面表示後Ｎ秒以内にユーザーによるロック解除操作が検知されずにＮ秒経過後に検知された場合には、上記ロック画面の検出感度が高感度に設定されてしまう。したがって、素手であるにも拘わらず上記検出感度が高感度に設定されることになる。しかしながら、上記ステップＳ6においてポップアップ表示によってユーザーの意思を確認するので、素手による操作時の誤設定をなくすことができる。 In the above configuration, when an operation with a bare hand is detected after N seconds have elapsed without being detected by the user within N seconds after displaying the lock screen for some reason, The detection sensitivity is set to high sensitivity. Therefore, the detection sensitivity is set to a high sensitivity regardless of the bare hand. However, since the user's intention is confirmed by the pop-up display in the above step S6, it is possible to eliminate an erroneous setting during operation with bare hands.
　その場合、上記ロック画面の検出感度が高感度に設定されてから素手によるロック解除が検知されるまでの時間は、高々Ｍ秒である。したがって、素手による操作時における誤動作を最小限に抑えることができる。 In this case, the time from when the lock screen detection sensitivity is set to high sensitivity until unlocking by bare hands is detected is at most M seconds. Therefore, it is possible to minimize malfunctions during operation with bare hands.
　・第２実施の形態
　本実施の形態は、上記感度設定処理動作の他の例に関する。本実施の形態の携帯情報端末装置の機能構成は、上記第１実施の形態における図１と同じである。したがって、本実施の形態における機能構成の詳細な説明は省略すると共に、図１と同じ番号を用いて説明を行う。 Second Embodiment The present embodiment relates to another example of the sensitivity setting processing operation. The functional configuration of the portable information terminal device of the present embodiment is the same as that of FIG. 1 in the first embodiment. Therefore, a detailed description of the functional configuration in the present embodiment will be omitted, and description will be made using the same numbers as those in FIG.
　以下、本実施の形態の携帯情報端末装置１による感度設定処理動作について詳細に説明する。 Hereinafter, the sensitivity setting processing operation by the portable information terminal device 1 of the present embodiment will be described in detail.
　本実施の形態においても、上記第１実施の形態の場合と同様に、タッチパネル２上に表示されるソフトキーで成るロック解除ボタンに対するユーザーの操作を利用して感度設定処理を行うようにしている。すなわち、上記ロック画面上に検出感度の異なるロック解除ボタンを複数用意し、タッチされたロック解除ボタンの上記検出感度に基づいて上記タッチセンサーの検出感度を設定するのである。 Also in the present embodiment, as in the case of the first embodiment, the sensitivity setting process is performed using the user's operation on the unlock button formed of the soft key displayed on the touch panel 2. . That is, a plurality of unlock buttons having different detection sensitivities are prepared on the lock screen, and the detection sensitivity of the touch sensor is set based on the detection sensitivity of the touched unlock button.
　図４は、上記制御処理部８による制御の下に実行される感度設定処理動作のフローチャートである。ユーザーによって電源ボタン６が押下されると、感度設定処理動作がスタートする。 FIG. 4 is a flowchart of the sensitivity setting process operation executed under the control of the control processing unit 8. When the power button 6 is pressed by the user, the sensitivity setting processing operation starts.
　ステップＳ11で、上記入出力制御部３によって、図５に例示するように、タッチパネル２に、素手によるタッチを前提とした通常感度用のロック解除ボタン１０と、上記通常感度よりも高い高感度用の高感度ロック解除ボタン１１とを含む上記ロック画面が表示される。ステップＳ12で、感度調整部４によって、上記ロック画面におけるロック解除ボタン１０の表示領域の検出感度が上記通常感度に、高感度ロック解除ボタン１１の表示領域の検出感度が上記高感度に、ロック解除ボタン１０,１１以外の全領域の検出感度が上記通常感度に初期設定される。ここで、上記ロック画面の検出感度の初期値は、予め記憶部５に記憶されている。 In step S11, as illustrated in FIG. 5, the input / output control unit 3 causes the touch panel 2 to have the unlock button 10 for normal sensitivity on the premise of touch with bare hands, and for high sensitivity higher than the normal sensitivity. The lock screen including the high-sensitivity lock release button 11 is displayed. In step S12, the sensitivity adjustment unit 4 unlocks the lock screen so that the detection sensitivity of the display area of the unlock button 10 is the normal sensitivity and the detection sensitivity of the display area of the high sensitivity unlock button 11 is the high sensitivity. The detection sensitivity of all areas other than the buttons 10 and 11 is initially set to the normal sensitivity. Here, the initial value of the detection sensitivity of the lock screen is stored in the storage unit 5 in advance.
　例えば、上記高感度ロック解除ボタン１１の検出感度の初期設定は、タッチパネル２が静電容量タイプのタッチパネルである場合には、タッチパネル２に対するタッチを検出する際の静電容量の閾値を、高感度ロック解除ボタン１１に該当する領域のみを他の領域よりも相対的に低く設定すればよい。 For example, when the touch panel 2 is a capacitance type touch panel, the initial setting of the detection sensitivity of the high sensitivity unlock button 11 is a threshold value of the capacitance when detecting a touch on the touch panel 2. Only the area corresponding to the unlock button 11 may be set lower than the other areas.
　ユーザーは、上記ロック画面のロック解除ボタン１０あるいは高感度ロック解除ボタン１１にタッチして下方向にスライドすることによってロック解除を行うことができる。 The user can unlock by touching the unlock button 10 or the high sensitivity unlock button 11 on the lock screen and sliding downward.
　ステップＳ13で、上記入出力制御部３から入力される上記タッチ検出信号に基づいて、上記ロック画面表示後Ｍ秒以内に、ユーザーによるロック解除操作が検知されたか否かが判別される。その結果、検知された場合にはステップＳ14に進み、検知されない場合にはステップＳ11にリターンして上記ロック画面の起動が行われる。 In step S13, based on the touch detection signal input from the input / output control unit 3, it is determined whether or not an unlock operation by the user has been detected within M seconds after the lock screen is displayed. As a result, if detected, the process proceeds to step S14. If not detected, the process returns to step S11 to activate the lock screen.
　ステップＳ14で、上記ステップＳ13において検知されたロック解除操作は、通常感度のロック解除ボタン１０に対する操作か否かが判別される。その結果、ロック解除ボタン１０に対する操作である場合にはユーザーは素手であると判定してステップＳ18に進み、そうでなければステップＳ15に進む。 In step S14, it is determined whether or not the unlocking operation detected in step S13 is an operation on the unlock button 10 having the normal sensitivity. As a result, if the operation is for the unlock button 10, the user is determined to be bare and proceeds to step S18, otherwise proceeds to step S15.
　ステップＳ15で、ユーザーの意思を確認するために、問い合わせ文「高感度モードで起動しますか？」と、上記ソフトキーで成る「Yes」ボタンおよび「No」ボタンとを含む画面がポップアップ表示される。その場合、少なくとも「Yes」ボタンの領域は手袋装着時に反応可能なように高感度の検出感度に設定される。 In step S15, in order to confirm the user's intention, a screen including an inquiry sentence “Do you want to start in high sensitivity mode?” And the “Yes” button and “No” button consisting of the above soft keys pops up. The In that case, at least the area of the “Yes” button is set to a high detection sensitivity so that it can react when wearing gloves.
　ステップＳ16で、上記入出力制御部３から入力される上記タッチ検出信号に基づいて、上記ポップアップに対するユーザーの選択が「Yes」であるか否かが判別される。その結果、「Yes」である場合にはステップＳ17に進む一方、「Yes」ではない(「No」である)場合にはステップＳ18に進む。 In step S16, based on the touch detection signal input from the input / output control unit 3, it is determined whether or not the user's selection for the pop-up is “Yes”. As a result, if “Yes”, the process proceeds to step S 17, while if not “Yes” (“No”), the process proceeds to step S 18.
　ステップＳ17で、上記感度調整部４によって、制御処理部８からの指示に基づいて、タッチパネル２における上記位置入力デバイスの上記検出感度が高感度に設定される。こうして、タッチパネル２の上記表示デバイスに表示される総ての画面に対するタッチの検出感度が高感度に本設定される。 In step S17, the sensitivity adjustment unit 4 sets the detection sensitivity of the position input device on the touch panel 2 to high sensitivity based on an instruction from the control processing unit 8. Thus, the touch detection sensitivity for all the screens displayed on the display device of the touch panel 2 is set to a high sensitivity.
　そうした後、上記感度設定処理動作が終了されて、ロック解除処理動作に移行する。 After that, the above sensitivity setting processing operation is terminated, and the process proceeds to the unlock processing operation.
　ステップＳ18で、上記感度調整部４によって、制御処理部８からの指示に基づいて、タッチパネル２における上記検出感度が通常感度に設定される。こうして、タッチパネル２の上記表示デバイスに表示される総ての画面に対するタッチの検出感度が通常感度に本設定される。 In step S18, the sensitivity adjustment unit 4 sets the detection sensitivity of the touch panel 2 to the normal sensitivity based on an instruction from the control processing unit 8. Thus, the touch detection sensitivity for all the screens displayed on the display device of the touch panel 2 is set to the normal sensitivity.
　そうした後、上記感度設定処理動作が終了されて、ロック解除処理動作に移行する。 After that, the above sensitivity setting processing operation is terminated, and the process proceeds to the unlock processing operation.
　以上のごとく、本実施の形態においては、ユーザーによって電源ボタン６が押下されると、タッチパネル２に通常感度のロック解除ボタン１０と高感度の高感度ロック解除ボタン１１とを含む上記ロック画面を表示し、上記ロック画面のロック解除ボタン１０,１１以外の領域の検出感度を上記通常感度に初期設定する。そうした後、入出力制御部３からの上記タッチ検出信号に基づいて、ユーザーによるロック解除操作が検知されたか否かを判別する。 As described above, in the present embodiment, when the power button 6 is pressed by the user, the lock screen including the normal sensitivity unlock button 10 and the high sensitivity high sensitivity unlock button 11 is displayed on the touch panel 2. Then, the detection sensitivity of the area other than the lock release buttons 10 and 11 on the lock screen is initialized to the normal sensitivity. After that, based on the touch detection signal from the input / output control unit 3, it is determined whether or not an unlocking operation by the user has been detected.
　そして、上記ロック解除操作がロック解除ボタン１０に対する操作である場合には、感度調整部４によって、タッチパネル２に対する上記検出感度が通常感度に本設定される。これに対し、上記ロック解除操作が高感度ロック解除ボタン１１に対する操作である場合には、高感度に本設定される。 When the unlocking operation is an operation with respect to the unlocking button 10, the sensitivity adjustment unit 4 sets the detection sensitivity for the touch panel 2 to the normal sensitivity. On the other hand, when the unlocking operation is an operation with respect to the high-sensitivity unlock button 11, the main setting is performed with high sensitivity.
　端的に言えば、手袋装着時にタッチ操作が可能な高感度ロック解除ボタン１１をタッチパネル２上の位置的に限定して設けることによって、ロック解除と検出感度設定とを同時に行うようにしている。 In short, the high-sensitivity unlock button 11 that can be touched when wearing gloves is limited in position on the touch panel 2 so that unlocking and detection sensitivity setting are performed simultaneously.
　したがって、上記メカニカルスイッチや上記加速度センサ等の特別なデバイスを設けることなく、手袋をした状態で上記検出感度を切り替えることができる。したがって、タッチパネル２の上記検出感度の切り替え時の利便性を高めることができる。 Therefore, the detection sensitivity can be switched in a gloved state without providing a special device such as the mechanical switch or the acceleration sensor. Therefore, convenience at the time of switching the detection sensitivity of the touch panel 2 can be enhanced.
　また、その際に、上記ロック画面におけるロック解除ボタン１０,１１に対するユーザーの操作を利用して感度設定処理を行うようにしている。したがって、タッチパネル２の上記検出感度切替用の専用の回路を追加設置したり、特別な処理を追加実行したりする必要がなく、消費電力の増加を抑制することができるのである。 At this time, the sensitivity setting process is performed using the user's operation on the unlock buttons 10 and 11 on the lock screen. Therefore, it is not necessary to additionally install a dedicated circuit for switching the detection sensitivity of the touch panel 2 or to additionally execute special processing, and an increase in power consumption can be suppressed.
　ここで、上記構成においては、上記タッチパネル２に通常感度のロック解除ボタン１０と高感度な高感度ロック解除ボタン１１とを含む上記ロック画面を、図５のごとく表示するようにしている。したがって、上記ロック画面上における高感度領域が高感度ロック解除ボタン１１の領域に限定され、素手による操作時において高感度領域に対する誤操作の発生を抑制することができる。 Here, in the above configuration, the lock screen including the normal sensitivity lock release button 10 and the high sensitivity high sensitivity lock release button 11 is displayed on the touch panel 2 as shown in FIG. Therefore, the high sensitivity area on the lock screen is limited to the area of the high sensitivity unlock button 11, and it is possible to suppress the occurrence of an erroneous operation on the high sensitivity area when operating with bare hands.
　尚、上記各実施の形態においては、上記検出感度が高感度に設定されたロック解除ボタンが操作された場合には、ユーザーに対して、問い合わせ文「高感度モードで起動しますか？」を含む画面をポップアップ表示して、ユーザーの意思を確認するようにしている。しかしながら、この確認は必ずしも必要ではない。 In each of the above embodiments, when the unlock button with the detection sensitivity set to high sensitivity is operated, an inquiry sentence “Do you want to start in high sensitivity mode?” The screen that contains it is displayed in a pop-up to confirm the user's intention. However, this confirmation is not always necessary.
　また、上記各実施の形態においては、上記「高感度」として唯一つの感度値を割り当てているが、上記「通常感度」よりも高い複数の感度値を割り当てることも可能である。その場合、上記第１実施の形態では、上記高感度を複数段に順次切り替え設定しながらロック解除操作の検知の有無を判定すればよい。また、上記第２実施の形態では、高感度ロック解除ボタン１１を複数のボタンで構成し、異なる感度値を割り当てればよい。そうすることによって、ユーザーが装着している手袋の生地の厚さや素材による指の導電性の変化に対処することが可能になる。 In the above embodiments, only one sensitivity value is assigned as the “high sensitivity”. However, a plurality of sensitivity values higher than the “normal sensitivity” can be assigned. In that case, in the first embodiment, the presence or absence of detection of the unlocking operation may be determined while sequentially setting the high sensitivity to a plurality of stages. In the second embodiment, the high-sensitivity unlock button 11 may be composed of a plurality of buttons, and different sensitivity values may be assigned. By doing so, it becomes possible to cope with changes in the conductivity of the finger due to the thickness of the glove fabric worn by the user and the material.
