　第一の実施形態による端末装置１は、図１で示した端末装置１の構成と同様に、検出部２と、判定部３と、変更部４と、入力部５とを備える。 <First embodiment>
FIG. 2 is a diagram showing a configuration of the terminal device 1 according to the first embodiment of the present invention.
The terminal device 1 by 1st embodiment is provided with the detection part 2, the determination part 3, the change part 4, and the input part 5 similarly to the structure of the terminal device 1 shown in FIG.
　本実施形態による端末装置１は、さらに表示部６および記憶部１１備える。入力部５は、タッチパネルであってもよい。表示部６は液晶ディスプレイであってもよい。記憶部１１は、ＲＯＭやＲＡＭであってもよい。
　本実施形態において、表示部６は、アイコン２２を表示する。 The terminal device 1 according to the present embodiment further includes a display unit 6 and a storage unit 11. The input unit 5 may be a touch panel. The display unit 6 may be a liquid crystal display. The storage unit 11 may be a ROM or a RAM.
In the present embodiment, the display unit 6 displays an icon 22.
　本実施形態の判定部３は、検出部２が検出するユーザ操作によって入力部５を構成する物理量検出素子に生じる物理量を統計することにより統計値を算出する。さらに、判定部３は、その統計値に基づいて入力部５に入力されたユーザ操作の特徴を判定する。
　物理量検出素子に生じる物理量とは、本実施形態においては、例えば静電容量素子２１に生じる静電容量である。 The determination unit 3 according to the present embodiment calculates a statistical value by statistically calculating a physical quantity generated in a physical quantity detection element constituting the input unit 5 by a user operation detected by the detection unit 2. Furthermore, the determination unit 3 determines the feature of the user operation input to the input unit 5 based on the statistical value.
In this embodiment, the physical quantity generated in the physical quantity detection element is, for example, an electrostatic capacity generated in the capacitive element 21.
　図３Ａは、端末装置１の表示部６に表示されるアイコン２２と静電容量素子２１の配列例を示している。図３Ｂ～３Ｄは、本発明の第一の実施形態による検出部２の検出する操作領域Ｅとタップ時間の例を示す図である。
　静電容量素子２１は、アイコン２２に対するタップを検出する。
　検出部２は、ユーザがアイコン２２をタップする際に生じる図３Ａの各静電容量素子２１の静電容量の変化を検出する。また、検出部２は、ユーザがタップした時間も同時に検出する。各静電容量素子２１には、静電容量のしきい値ｔｈが設けられている。検出部２は、静電容量のしきい値ｔｈを超えた静電容量素子２１を含む領域をユーザが指でアイコン２２に接触させた領域として検出する。検出部２は、静電容量のしきい値ｔｈを超えた静電容量素子２１を含む領域をユーザが指でアイコン２２に近接させた領域として検出してもよい。 FIG. 3A shows an arrangement example of the icons 22 and the capacitive elements 21 displayed on the display unit 6 of the terminal device 1. 3B to 3D are diagrams showing examples of the operation region E and the tap time detected by the detection unit 2 according to the first embodiment of the present invention.
The capacitive element 21 detects a tap on the icon 22.
The detection unit 2 detects a change in capacitance of each capacitance element 21 in FIG. 3A that occurs when the user taps the icon 22. Moreover, the detection part 2 detects simultaneously the time tapped by the user. Each capacitance element 21 is provided with a capacitance threshold th. The detection unit 2 detects a region including the capacitive element 21 that exceeds the capacitance threshold th as a region in which the user has touched the icon 22 with a finger. The detection unit 2 may detect a region including the capacitive element 21 that exceeds the threshold value th of the capacitance as a region in which the user has approached the icon 22 with a finger.
　図３Ｂは、アイコン２２に対してユーザＡが指でタップしたときに、検出部２がユーザＡの指の接触または近接を検出する操作領域Ｅを示している。図３Ｃは、アイコン２２に対してユーザＢが指でタップしたときに、検出部２がユーザＢの指の接触または近接を検出する操作領域Ｅを示している。図３Ｄは、アイコン２２に対してユーザＣが指でタップしたときに、検出部２がユーザＣの指の接触または近接を検出する操作領域Ｅを示している。
　ユーザ毎に、指の大きさも異なり、またアイコン２２に指を近づける速度やアイコン２２をタップするときの力の入れ具合も異なる。このため、ユーザ毎に、検出部２がしきい値ｔｈを超えた静電容量素子２１を含む領域として検出する操作領域Ｅの面積や外形は異なる。
　検出部２は、図３Ａに示す静電容量素子２１各々に対してその配置に対応する識別子である例えば識別番号を付与する。検出部２は、しきい値ｔｈを超えた静電容量素子２１の識別番号をリストとして記憶部１１に記録する。
　検出部２は、例えば、静電容量素子２１における静電容量の単位面積当たりの平均値がしきい値ｔｈを超えていた時間であるタップ時間を検出する。検出部２は、タップ時間が所定の時間以上である場合にユーザがタップしたと判断する。タップ時間はユーザ毎に異なる。静電容量の単位面積当たりの平均値は、所定値（例えば、０）を超える静電容量が検出された各静電容量素子２１における静電容量の合計を、所定値を超える静電容量が検出された各静電容量素子２１の面積の合計で割った値であってもよい。静電容量の単位面積当たりの平均値は各タップにおいて検出された最大の静電容量の合計値に基づいて算出してもよい。 FIG. 3B shows an operation area E where the detection unit 2 detects contact or proximity of the finger of the user A when the user A taps the icon 22 with a finger. FIG. 3C shows an operation area E in which the detection unit 2 detects contact or proximity of the finger of the user B when the user B taps the icon 22 with a finger. FIG. 3D shows an operation area E where the detection unit 2 detects contact or proximity of the finger of the user C when the user C taps the icon 22 with a finger.
The size of the finger is different for each user, and the speed at which the finger is brought close to the icon 22 and the force applied when the icon 22 is tapped are also different. For this reason, the area and outer shape of the operation region E detected by the detection unit 2 as a region including the capacitive element 21 exceeding the threshold value th are different for each user.
The detection unit 2 assigns, for example, an identification number, which is an identifier corresponding to the arrangement, to each of the capacitance elements 21 illustrated in FIG. 3A. The detection unit 2 records the identification numbers of the capacitive elements 21 that exceed the threshold th in the storage unit 11 as a list.
For example, the detection unit 2 detects a tap time that is a time during which the average value per unit area of the capacitance in the capacitance element 21 exceeds the threshold th. The detection unit 2 determines that the user has tapped when the tap time is equal to or longer than a predetermined time. The tap time is different for each user. The average value per unit area of the electrostatic capacity is the total of the electrostatic capacity in each electrostatic capacitance element 21 in which the electrostatic capacity exceeding a predetermined value (for example, 0) is detected. A value obtained by dividing the total area of the detected capacitance elements 21 may be used. The average value per unit area of the capacitance may be calculated based on the total value of the maximum capacitance detected at each tap.

　図５は、本発明の第一の実施形態による端末装置１の処理フローを示す図である。
　次に、第一の実施形態による端末装置１の処理フローを説明する。この実施形態による端末装置１の処理フローは、端末装置１がユーザがアイコン２２をタップする特徴からユーザを特定する場合の例である。 FIG. 5 is a diagram showing a processing flow of the terminal device 1 according to the first embodiment of the present invention.
Next, the processing flow of the terminal device 1 according to the first embodiment will be described. The processing flow of the terminal device 1 according to this embodiment is an example in which the terminal device 1 specifies a user from the feature that the user taps the icon 22.
　ユーザは、まず、自身のアイコン２２に対するタップ操作の特徴を端末装置１に学習させる。具体的には、ユーザは、アイコン２２に対するタップ操作を繰り返し行う。
　検出部２は、このタップ操作による静電容量の平均値（および平均値の変移）を、ユーザの特徴として記憶部１１に記憶する（ステップＳ１）。ステップＳ１の処理は、各ユーザについて行う。
　検出部２は、静電容量の平均値に加えてあるいはその代わりに、以下の情報をユーザの特徴として記憶部１１に記憶してもよい。すなわち、検出部２は、図３Ｂ～３Ｄで示すような検出部２によって静電容量がしきい値ｔｈを超えたと検出された静電容量素子２１の識別番号のリストをユーザの特徴として記憶部１１に記憶してもよい。検出部２は、図４Ａ～４Ｃで示すようなユーザのアイコン２２のタップ時間をユーザの特徴として記憶部１１に記憶してもよい。
　検出部２は、ステップＳ１の後にユーザが端末装置１を通常使用した時の操作に基づくデータを取得し、そのデータをステップＳ１で記憶部１１に記憶させたデータに加えることによりユーザの特徴を示すデータを更新してもよい。 First, the user causes the terminal device 1 to learn the characteristics of the tap operation on the icon 22 of the user. Specifically, the user repeatedly performs a tap operation on the icon 22.
The detection unit 2 stores the average value of the capacitance (and the change of the average value) by the tap operation in the storage unit 11 as a user characteristic (step S1). The process of step S1 is performed for each user.
The detection unit 2 may store the following information in the storage unit 11 as user characteristics in addition to or instead of the average value of the capacitance. That is, the detection unit 2 stores a list of identification numbers of the capacitive elements 21 detected as having exceeded the threshold th by the detection unit 2 as shown in FIGS. 3B to 3D as user characteristics. 11 may be stored. The detection unit 2 may store the tap time of the user icon 22 as shown in FIGS. 4A to 4C in the storage unit 11 as a user characteristic.
The detection unit 2 acquires data based on an operation when the user normally uses the terminal device 1 after step S1, and adds the data to the data stored in the storage unit 11 in step S1 to characterize the user. The data shown may be updated.
　その後、ユーザは、特に意識することなく、端末装置１を通常通りに使用する。このとき、検出部２はユーザ操作により各静電容量素子２１に生じる静電容量を検出する（ステップＳ２）。 Thereafter, the user uses the terminal device 1 as usual without any particular attention. At this time, the detection part 2 detects the electrostatic capacitance which arises in each electrostatic capacitance element 21 by user operation (step S2).
　判定部３は、ユーザの通常使用時の静電容量素子２１における静電容量の単位面積当たりの平均値の算出を所定回数行う。次に、判定部３は、所定回数分の静電容量の単位面積当たりの平均値の平均値を統計値として算出する。判定部３は、統計値として算出された平均値（以下において、通常の使用時におけるユーザの平均値と称する場合がある）を現在のユーザ操作の特徴に設定する（ステップＳ３）。 The determination unit 3 calculates the average value per unit area of the capacitance in the capacitance element 21 during normal use by the user a predetermined number of times. Next, the determination unit 3 calculates an average value of the average value per unit area of the electrostatic capacity for a predetermined number of times as a statistical value. The determination unit 3 sets an average value calculated as a statistical value (hereinafter may be referred to as a user average value during normal use) as a feature of the current user operation (step S3).
　判定部３は、学習時における各ユーザの操作の特徴を示す静電容量の単位面積当たりの平均値（以下において、学習時における各ユーザの平均値と称する場合がある）を記憶部１１から読み出す（ステップＳ４）。 The determination unit 3 reads from the storage unit 11 an average value per unit area of capacitance indicating characteristics of each user's operation at the time of learning (hereinafter may be referred to as an average value of each user at the time of learning). (Step S4).
　判定部３は、通常の使用時におけるユーザの平均値と、学習時における各ユーザの平均値とを比較する（ステップＳ５）。 The determination unit 3 compares the average value of the user during normal use with the average value of each user during learning (step S5).
　判定部３は、検出部２がしきい値ｔｈを超えたと検出した静電容量素子２１の識別番号のリストやタップ時間などの現在のユーザ操作の特徴と記憶部１１から読み出した（学習時の）ユーザ操作の特徴とを比較してもよい（ステップＳ６）。 The determination unit 3 reads the current user operation features such as a list of identification numbers and tap times of the capacitive elements 21 detected by the detection unit 2 as exceeding the threshold th and the storage unit 11 (at the time of learning). ) The user operation characteristics may be compared (step S6).
　判定部３は、ステップＳ５とステップＳ６とにおける比較結果に基づいて、現在使用しているユーザの特徴と最も近い特徴のユーザが現在使用しているユーザであると特定する（ステップＳ７）。
　判定部３は、ステップＳ５またはステップＳ６の何れか１つのステップに基づいて現在使用しているユーザを特定してもよい。 Based on the comparison result in step S5 and step S6, the determination unit 3 specifies that the user having the closest feature to the feature of the currently used user is the user currently using (step S7).
The determination unit 3 may specify the user currently in use based on any one of step S5 and step S6.
　判定部３がユーザを特定すると、変更部４は、特定されたユーザが利用メニューに応じて予め記憶部１１に記憶した端末装置１の利用しやすい設定を読み出し、端末装置１の設定を読み出した設定に変更する（ステップＳ８）。
　具体的には、変更部４は、例えば、背景画像、アイコンの配置、利用できる機能を変更する。 When the determination unit 3 identifies the user, the changing unit 4 reads the settings that are easy to use for the terminal device 1 stored in the storage unit 11 in advance according to the usage menu by the identified user, and reads the settings for the terminal device 1. The setting is changed (step S8).
Specifically, the changing unit 4 changes, for example, the background image, icon arrangement, and available functions.
　図６Ａ～６Ｃは、検出部２が検出したアイコン２２における各静電容量素子２１に生じる静電容量の合計の時間変移の例を示す図である。図６Ａは、ユーザＡがアイコン２２をタップした場合を示す。図６Ｂは、ユーザＢがアイコン２２をタップした場合を示す。図６Ｃは、ユーザＣがアイコン２２をタップした場合を示す。
　判定部３は、図４Ａ～４Ｃで示した特性の代わりに図６Ａ～６Ｃに示す特性を利用してユーザを特定してもよい。
　判定部３が図６Ａ～６Ｃに示す特性を利用してユーザを特定する場合、検出部２が検出する静電容量の絶対値は、図４Ａ～４Ｃで示した静電容量よりも大きくなる。そのため、静電容量を検出する際に生じる検出部２の寄生容量による静電容量素子２１の静電容量への測定影響が相対的に小さくなる。その結果、静電容量の検出精度が向上する。
　また、判定部３が図６Ａ～６Ｃに示す特性を利用してユーザを特定する場合、検出部２が検出する静電容量の合計値の最大値は、ユーザ毎の指の大きさの違いによりばらつく。そのため、判定部３は、その最大値を使用することによりユーザを特定しやすくなる。その結果、ユーザの判別精度がより高まる。 6A to 6C are diagrams showing examples of time transition of the total capacitance generated in each capacitance element 21 in the icon 22 detected by the detection unit 2. FIG. FIG. 6A shows a case where the user A taps the icon 22. FIG. 6B shows a case where the user B taps the icon 22. FIG. 6C shows a case where the user C taps the icon 22.
The determination unit 3 may specify the user using the characteristics shown in FIGS. 6A to 6C instead of the characteristics shown in FIGS. 4A to 4C.
When the determination unit 3 specifies a user using the characteristics shown in FIGS. 6A to 6C, the absolute value of the capacitance detected by the detection unit 2 is larger than the capacitance shown in FIGS. 4A to 4C. Therefore, the measurement influence on the capacitance of the capacitance element 21 due to the parasitic capacitance of the detection unit 2 that occurs when detecting the capacitance is relatively reduced. As a result, the capacitance detection accuracy is improved.
When the determination unit 3 specifies a user using the characteristics shown in FIGS. 6A to 6C, the maximum value of the total capacitance detected by the detection unit 2 depends on the difference in finger size for each user. It varies. Therefore, the determination unit 3 can easily identify the user by using the maximum value. As a result, the user's discrimination accuracy is further increased.
　検出部２が検出する物理量は、静電容量に限定されない。検出部２が検出する物理量は、端末装置１に対するユーザの操作によって入力部５を構成する物理量検出素子に生じる物理量であり、ユーザを特定できる物理量であればどのような物理量であってもよい。
　例えば、タッチパネル技術には、上述の静電容量方式以外に、抵抗膜方式、ＳＡＷ（表面弾性波）、赤外線、歪ゲージ、光画像処理、分散信号、音響などの方式がある。これらを検出部２が検出する物理量としてもよい。 The physical quantity detected by the detection unit 2 is not limited to the capacitance. The physical quantity detected by the detection unit 2 is a physical quantity generated in the physical quantity detection element constituting the input unit 5 by the user's operation on the terminal device 1, and may be any physical quantity as long as it can identify the user.
For example, touch panel technology includes methods such as a resistive film method, SAW (surface acoustic wave), infrared light, strain gauge, optical image processing, distributed signal, and sound in addition to the capacitance method described above. These may be physical quantities detected by the detection unit 2.
　以上、第一の実施形態による端末装置１の処理フローについて説明した。上述の端末装置１によれば、記憶部１１は、ユーザの端末装置１に対する操作の特徴を記憶している。そのユーザが端末装置１を使用した場合に、判定部３が端末装置１を使用中のユーザを特定することができる。変更部４が特定したユーザに適した使用環境を提供する。その結果、ユーザは意識することなく端末装置１の使用しやすい環境を得ることができる。 The processing flow of the terminal device 1 according to the first embodiment has been described above. According to the terminal device 1 described above, the storage unit 11 stores the characteristics of the user's operation on the terminal device 1. When the user uses the terminal device 1, the determination unit 3 can specify a user who is using the terminal device 1. A use environment suitable for the user specified by the changing unit 4 is provided. As a result, it is possible to obtain an environment in which the user can use the terminal device 1 without being aware of it.
＜第二の実施形態＞
　次に、第二の実施形態による端末装置１の処理フローについて説明する。
　第二の実施形態による端末装置１は、図２で示した第一の実施形態の端末装置１と同様に、検出部２と、判定部３と、変更部４と、入力部５と、表示部６と、記憶部１１とを備える。第二の実施形態において、入力部５はタッチパネルである。以下において、入力部５をタッチパネル５と表記する場合がある。 <Second Embodiment>
Next, a processing flow of the terminal device 1 according to the second embodiment will be described.
The terminal device 1 according to the second embodiment is similar to the terminal device 1 according to the first embodiment shown in FIG. 2, and includes a detection unit 2, a determination unit 3, a change unit 4, an input unit 5, and a display. Unit 6 and storage unit 11. In the second embodiment, the input unit 5 is a touch panel. Hereinafter, the input unit 5 may be referred to as a touch panel 5.
　第二の実施形態による検出部２および判定部３は、以下の点において、第一の実施形態による検出部２および判定部３と異なる。すなわち、検出部２は、静電容量素子２１の静電容量の変移に基づいて、ユーザの指の軌跡である操作経過を検出する。判定部３は、その検出の結果に基づいて入力部５へ行う操作の特徴を判定する。 The detection unit 2 and the determination unit 3 according to the second embodiment are different from the detection unit 2 and the determination unit 3 according to the first embodiment in the following points. That is, the detection unit 2 detects an operation progress that is a locus of the user's finger based on the change in capacitance of the capacitance element 21. The determination unit 3 determines the characteristics of the operation performed on the input unit 5 based on the detection result.
　図７Ａは、本発明の第二の実施形態による端末装置１のロック解除時に表示部６に表示されるロック解除画面Ｓを示す。図７Ｂ～７Ｄは、ロック解除時に検出部２が検出する指の軌跡の例を示す。図７Ｂは、ユーザＡの指の軌跡の例を示す。図７Ｃは、ユーザＢの指の軌跡の例を示す。図７Ｄは、ユーザＣの指の軌跡の例を示す。
　図７Ａは、端末装置１のロックを解除するために指でなぞらなければならないガイド表示Ｇである、３行３列の丸印を示している。図７Ａにおけるガイド表示Ｇの各丸印内の数字は、指でなぞる順番を示しており、実際のロック解除画面Ｓには表示されない。 FIG. 7A shows an unlock screen S displayed on the display unit 6 when the terminal device 1 according to the second embodiment of the present invention is unlocked. 7B to 7D show examples of finger trajectories detected by the detection unit 2 when unlocking. FIG. 7B shows an example of the locus of the finger of user A. FIG. 7C shows an example of the trajectory of user B's finger. FIG. 7D shows an example of the locus of the finger of user C.
FIG. 7A shows a 3 × 3 circle that is a guide display G that must be traced with a finger to unlock the terminal device 1. The numbers in each circle in the guide display G in FIG. 7A indicate the order of tracing with a finger, and are not displayed on the actual unlock screen S.
　図７Ｂ～７Ｄは、それぞれ、ユーザＡ、Ｂ、Ｃが図７Ａに示すロック解除画面Ｓに対して、丸印内の番号‘１’、‘２’、‘３’の順に指をなぞった軌跡の例である。検出部２は、ユーザがロック解除のために丸印を指でなぞる際に生じる静電容量を検出する。検出部２は、図４Ａ～４Ｃで示した場合と同様に、各静電容量素子２１の静電容量にしきい値を設けて、静電容量がそのしきい値を超えた静電容量素子２１を検出する。図７Ｂ～７Ｄに示す各ユーザの軌跡を示す矢印Ｒは、静電容量がしきい値を超えた静電容量素子２１を示している。
　また、検出部２は、しきい値を超えた静電容量を有する電容量素子２１が検出された時間を取得する。 FIGS. 7B to 7D are traces in which the users A, B, and C trace their fingers in the order of numbers “1”, “2”, and “3” in the circles on the unlock screen S shown in FIG. 7A, respectively. It is an example. The detection unit 2 detects a capacitance generated when the user traces a circle with a finger for unlocking. As in the case shown in FIGS. 4A to 4C, the detection unit 2 sets a threshold value for the capacitance of each capacitance element 21, and the capacitance element 21 whose capacitance has exceeded the threshold value. Is detected. An arrow R indicating the locus of each user shown in FIGS. 7B to 7D indicates the electrostatic capacitance element 21 whose electrostatic capacitance exceeds the threshold value.
In addition, the detection unit 2 acquires the time when the capacitive element 21 having a capacitance exceeding the threshold is detected.
　図７Ｂ～７Ｄに示す矢印Ｒの線の太さは、ユーザがタッチパネル５を指で押す力の大きさを示している。ユーザがタッチパネル５を押す力が大きい場合、タッチパネル５と指との接触面積が大きくなる。その結果、検出部２が検出する静電容量の総和が大きくなる。 7B to 7D indicate the magnitude of the force of the user pressing the touch panel 5 with a finger. When the force with which the user presses the touch panel 5 is large, the contact area between the touch panel 5 and the finger increases. As a result, the total capacitance detected by the detection unit 2 is increased.
　図７Ｂに示す例において、ユーザＡが指をなぞった時間は０．３秒である。図７Ｃに示す例において、ユーザＢが指をなぞった時間は０．５秒である。図７Ｄに示す例において、ユーザＣが指をなぞった時間は０．４秒である。
　図７Ｂから、ユーザＡは、丸印の番号‘１’、‘２’、‘３’の順に指をなぞった場合、指でタッチパネル５を強く押し、直線的に最短で指を移動するという特徴を持っていることがわかる。ユーザＡが指をなぞった時間は０．３秒なので、ユーザＢおよびＣよりも短い。 In the example shown in FIG. 7B, the time that the user A traces the finger is 0.3 seconds. In the example shown in FIG. 7C, the time for user B to trace his / her finger is 0.5 seconds. In the example shown in FIG. 7D, the time that the user C traces his / her finger is 0.4 seconds.
From FIG. 7B, when the user A traces his / her finger in the order of the numbers “1”, “2”, and “3” in the circle, the touch panel 5 is strongly pressed with the finger, and the finger is moved in the shortest linear manner. You can see that The time that user A traces his / her finger is 0.3 seconds, which is shorter than users B and C.
　図７Ｃから、ユーザＢは、丸印の番号‘１’、‘２’、‘３’の順に指をなぞった場合、指でタッチパネル５を強く押し、円を描くように指を移動するという特徴を持っていることがわかる。ユーザＢが指をなぞった時間は０．５秒なので、ユーザＡおよびＣよりも長い。
　図７Ｄから、ユーザＣは、丸印の番号‘１’、‘２’、‘３’の順に指をなぞった場合、指でタッチパネル５を弱く押し、直線的に勢いよく指を移動するという特徴を持っていることがわかる。ユーザＣが指をなぞった時間は０．４秒である。よって、ユーザＣの操作時間は、ユーザＡおよびＢと比べると、指の移動距離が長い割に短い。 From FIG. 7C, when the user B traces the finger in the order of the circle numbers “1”, “2”, and “3”, the user B strongly presses the touch panel 5 and moves the finger to draw a circle. You can see that The time for user B to trace his / her finger is 0.5 seconds, which is longer than that for users A and C.
From FIG. 7D, when the user C traces his / her finger in the order of the circle numbers “1”, “2”, and “3”, the touch panel 5 is gently pressed with the finger, and the finger C moves linearly and vigorously. You can see that The time for user C to trace his / her finger is 0.4 seconds. Therefore, the operation time of the user C is short compared to the users A and B, although the finger moving distance is long.
　判定部３は、ユーザ毎の特徴と記憶部１１に記憶した特徴と比較することにより、端末装置１を現在操作しているユーザを特定する。
　ユーザがタッチパネル５を押す力が強い場合、検出部２が検出する静電容量素子２１の数や全体の静電容量の変化が大きくなる。このようなデータはユーザの指の大きさの違いなどの特徴を示す。よって、判定部３は、このようなデータを利用することにより、より高精度にユーザを特定することができる。 The determination unit 3 identifies the user who is currently operating the terminal device 1 by comparing the feature for each user with the feature stored in the storage unit 11.
When the force with which the user presses the touch panel 5 is strong, the number of the capacitive elements 21 detected by the detection unit 2 and the change in the overall capacitance increase. Such data shows features such as differences in the size of the user's finger. Therefore, the determination unit 3 can specify the user with higher accuracy by using such data.
　図８は、本発明の第二の実施形態による端末装置１の処理フローを示す図である。
　次に、第二の実施形態による端末装置１の処理フローを説明する。
　この実施形態による端末装置１の処理フローは、ロック解除画面Ｓが表示されている状態においてユーザがタッチパネル５をなぞる特徴からユーザを特定する場合の例である。
　第二の実施形態による端末装置１の処理フローは、ステップＳ９とステップＳ１０との処理を行い、次に第一の実施形態による処理フローのステップＳ２の処理を行い、更にステップＳ１１～ステップＳ１３の処理を行う。 FIG. 8 is a diagram showing a processing flow of the terminal device 1 according to the second embodiment of the present invention.
Next, a processing flow of the terminal device 1 according to the second embodiment will be described.
The processing flow of the terminal device 1 according to this embodiment is an example in the case where the user specifies the user from the feature of tracing the touch panel 5 in the state where the unlock screen S is displayed.
The processing flow of the terminal device 1 according to the second embodiment performs the processing of step S9 and step S10, then performs the processing of step S2 of the processing flow according to the first embodiment, and further performs steps S11 to S13. Process.
　表示部６は、ユーザが長時間端末装置１に対して操作を行わない場合や他のユーザに使用されないようにロックを掛けた場合に用いるロック解除画面Ｓを表示している状況を想定する。また、表示部６は、ロック解除画面Ｓにロックを解除するためのガイド表示Ｇである丸印を表示している状況を想定する。 Suppose that the display unit 6 is displaying a lock release screen S that is used when the user does not operate the terminal device 1 for a long time or when the user locks the terminal device 1 so that it is not used by other users. Further, it is assumed that the display unit 6 displays a circle as a guide display G for releasing the lock on the lock release screen S.
　このような状況で、ユーザは、まず、ロック解除のためのガイド表示Ｇである丸印をなぞる操作の特徴を端末装置１に学習させる。具体的には、ユーザは、端末装置１に対して丸印をなぞる操作を繰り返し行う。
　検出部２は、ユーザのなぞる操作により静電容量がしきい値を超えた静電容量素子２１を検出し、検出した静電容量素子２１の識別番号のリストをユーザが指でなぞる軌跡として検出する（ステップＳ９）。 In such a situation, the user first causes the terminal device 1 to learn the characteristics of the operation of tracing the circle that is the guide display G for unlocking. Specifically, the user repeatedly performs an operation of tracing the circle on the terminal device 1.
The detection unit 2 detects the capacitance element 21 whose capacitance exceeds a threshold value by the user's tracing operation, and detects a list of identification numbers of the detected capacitance elements 21 as a trace traced by the user's finger. (Step S9).
　検出部２は、その検出した静電容量素子２１の識別番号のリストをユーザ操作の特徴として記憶部１１に記録する（ステップＳ１０）。
　記憶部１１が記録するユーザ操作の特徴は、例えば、図７Ｂ～７Ｄで示すような検出部２の検出したユーザの指の軌跡である。 The detection unit 2 records a list of the identification numbers of the detected capacitance elements 21 in the storage unit 11 as a feature of the user operation (step S10).
The feature of the user operation recorded by the storage unit 11 is, for example, the locus of the user's finger detected by the detection unit 2 as shown in FIGS. 7B to 7D.
　検出部２は、ステップＳ１０の後にユーザが端末装置１を通常使用した時の操作に基づくデータを取得し、そのデータをステップＳ１０で記憶部１１に記憶させたデータに加えることによりユーザの特徴を示すデータを更新してもよい。 The detection unit 2 acquires data based on an operation when the user normally uses the terminal device 1 after step S10, and adds the data to the data stored in the storage unit 11 in step S10, thereby adding the characteristics of the user. The data shown may be updated.
　その後、ユーザは、特に意識することなく、端末装置１を通常通りにロック解除のガイド表示Ｇの丸印をなぞる操作をする。このとき、検出部２はユーザ操作により入力部５を構成する各静電容量素子２１に生じる静電容量を検出する（ステップＳ２）。 After that, the user performs an operation of tracing the terminal device 1 in a circle of the unlocking guide display G as usual without being particularly conscious. At this time, the detection part 2 detects the electrostatic capacitance which arises in each electrostatic capacitance element 21 which comprises the input part 5 by user operation (step S2).
　判定部３は、静電容量がしきい値を超えた静電容量素子２１の識別番号のリストをロック解除操作におけるユーザが指でなぞる軌跡の特徴に設定する（ステップＳ１１）。 The determination unit 3 sets a list of identification numbers of the capacitance elements 21 whose capacitance has exceeded the threshold value as trajectory features that the user traces with the finger in the unlocking operation (step S11).
　判定部３は、複数のユーザそれぞれに対応付けられた学習時における静電容量がしきい値を超えた静電容量素子２１の識別番号の複数のリストを記憶部１１から読み出する。判定部３は、ロック解除操作における識別番号のリストと学習時における識別番号の複数のリストとを比較する。判定部３は、学習時における識別番号の複数のリストのうち、ロック解除操作における識別番号のリストと最も一致するリストに対応付けられているユーザを端末装置１を現在使用しているユーザであると特定する（ステップＳ１２）。 The determination unit 3 reads a plurality of lists of identification numbers of the capacitance elements 21 whose capacitances during learning associated with each of the plurality of users exceed a threshold value from the storage unit 11. The determination unit 3 compares the list of identification numbers in the unlocking operation with a plurality of lists of identification numbers during learning. The determination unit 3 is a user who is currently using the terminal device 1 for a user associated with a list that most closely matches the list of identification numbers in the unlocking operation among a plurality of lists of identification numbers during learning. (Step S12).
　判定部３がユーザを特定すると、変更部４は、端末装置１のロックを解除すると共に、特定されたユーザが利用メニューに応じて予め記憶部１１に記憶した端末装置１の利用しやすい設定を読み出し、端末装置１の設定を読み出した設定に変更する（ステップＳ１３）。
　別法として、このステップＳ１３で行う処理において、変更部４は、ロック解除操作におけるユーザの指の軌跡の特徴が学習時に記憶したユーザの指の軌跡の特徴と所定の割合以上一致しているか否か判断してもよい。この場合、変更部４は、ロック解除操作にユーザがたとえガイド表示Ｇである丸印を正しい順番になぞっていた場合であっても、ロック解除操作における軌跡の特徴が学習時の軌跡の特徴と所定の割合以上一致しなければロックを解除しなくてもよい。 When the determination unit 3 identifies the user, the changing unit 4 unlocks the terminal device 1 and sets the user-friendly setting of the terminal device 1 stored in the storage unit 11 in advance according to the usage menu by the identified user. Read and change the setting of the terminal device 1 to the read setting (step S13).
Alternatively, in the processing performed in step S13, the changing unit 4 determines whether or not the feature of the user's finger trajectory in the unlocking operation matches the feature of the user's finger trajectory stored during learning by a predetermined ratio or more. You may judge. In this case, the changing unit 4 determines that the trajectory feature in the unlocking operation is the trajectory feature at the time of learning even when the user traces the circles that are the guide display G in the correct order in the unlocking operation. The lock may not be released if they do not match a predetermined ratio or more.
　上述の第二の実施形態による判定部３が行うユーザの特定は、ガイド表示Ｇである丸印をユーザが指でなぞる操作により生じる各静電容量素子２１の静電容量に基づいて行うことに限定されない。
　例えば、判定部３は、検出部２が検出するユーザのスライド操作、なぞり操作、ページめくり（フリックやスクロール）操作などにより生じる各静電容量素子２１の静電容量に基づいてユーザを特定してもよい。 The identification of the user performed by the determination unit 3 according to the second embodiment described above is performed based on the capacitance of each capacitance element 21 generated by an operation in which the user traces the circle that is the guide display G with a finger. It is not limited.
For example, the determination unit 3 specifies the user based on the capacitance of each capacitance element 21 generated by the user's slide operation, tracing operation, page turning (flick or scroll) operation, etc. detected by the detection unit 2. Also good.
　以上、第二の実施形態による端末装置１の処理フローについて説明した。上述の端末装置１によれば、記憶部１１は、ユーザの端末装置１に対する操作の特徴を記憶している。そのユーザが端末装置１を使用した場合、検出部２は、ユーザが入力部５へ行う操作によって入力部５を構成する静電容量素子２１に生じる静電容量から指の軌跡などの操作経過を検出する。判定部３は、その検出結果に基づいて使用中のユーザを特定することができる。判定部３がユーザを特定することをロック解除のための条件の一つに追加することにより、より安全性の高い環境をユーザに提供することができる。 The processing flow of the terminal device 1 according to the second embodiment has been described above. According to the terminal device 1 described above, the storage unit 11 stores the characteristics of the user's operation on the terminal device 1.

By adding that the determination unit 3 identifies the user to one of the conditions for unlocking, a safer environment can be provided to the user.
＜第三の実施形態＞
　図９は、本発明の第三の実施形態による端末装置１の処理フローを示す図である。
　第三の実施形態による端末装置１は、図２で示した第一の実施形態の端末装置１と同様に、検出部２と、判定部３と、変更部４と、入力部５と、表示部６と、記憶部１１とを備える。 <Third embodiment>
FIG. 9 is a diagram showing a processing flow of the terminal device 1 according to the third embodiment of the present invention.
The terminal device 1 according to the third embodiment is similar to the terminal device 1 of the first embodiment shown in FIG. 2, and includes a detection unit 2, a determination unit 3, a change unit 4, an input unit 5, and a display. Unit 6 and storage unit 11.
　第三の実施形態による変更部４は、判定部３が判定するユーザの属性に応じて、ユーザが入力部５へ行う操作に対する端末装置１の応答を制限する点で第一の実施形態と異なる。 The changing unit 4 according to the third embodiment is different from the first embodiment in that the response of the terminal device 1 to an operation performed by the user on the input unit 5 is limited according to the user attribute determined by the determining unit 3. .
　次に、第三の実施形態による端末装置１の処理フローを説明する。
　この実施形態による端末装置１の処理フローは、端末装置１が、ユーザのアイコン２２をタップする特徴からユーザを特定する場合の例である。
　第三の実施形態による端末装置１の処理フローは、第一の実施形態によるステップＳ１～ステップＳ４の処理の次に、ステップＳ１５とステップＳ１６の処理を行う。 Next, a processing flow of the terminal device 1 according to the third embodiment will be described.
The processing flow of the terminal device 1 according to this embodiment is an example of the case where the terminal device 1 specifies a user from the feature of tapping the user icon 22.
In the processing flow of the terminal device 1 according to the third embodiment, the processing of step S15 and step S16 is performed after the processing of step S1 to step S4 according to the first embodiment.
　ユーザは、まず、自身のアイコンのタップ操作の特徴を端末装置１に学習させる。具体的には、ユーザは、端末装置１に対してアイコン２２のタップ操作を繰り返し行う。
　端末装置１の検出部２は、このタップ操作による静電容量の平均値（および平均値の変移）を、ユーザの特徴として記憶部１１に記憶する（ステップＳ１）。ステップＳ１の処理は、各ユーザについて行う。
　検出部２は、静電容量の平均値に加えてあるいはその代わりに、以下の情報をユーザの特徴として記憶部１１に記憶してもよい。すなわち、検出部２は、例えば、図３Ｂ～３Ｄで示すような検出部２によってしきい値を超えたと検出された静電容量素子２１の識別番号のリストをユーザの特徴として記憶部１１に記憶してもよい。検出部２は、図４Ａ～４Ｃで示すようなにユーザのアイコン２２のタップ時間をユーザの特徴として記憶部１１に記憶してもよい。
　検出部２は、ステップＳ１の後にユーザが端末装置１を通常使用した時の操作に基づくデータを取得し、そのデータをステップＳ１で記憶部１１に記憶させたデータに加えることによりユーザの特徴を示すデータを更新してもよい。 First, the user causes the terminal device 1 to learn the characteristics of the tap operation of his / her icon. Specifically, the user repeatedly performs the tap operation of the icon 22 on the terminal device 1.
The detection unit 2 of the terminal device 1 stores the average value of the capacitance (and the change in the average value) by the tap operation in the storage unit 11 as a user characteristic (step S1). The process of step S1 is performed for each user.
The detection unit 2 may store the following information in the storage unit 11 as user characteristics in addition to or instead of the average value of the capacitance. That is, for example, the detection unit 2 stores a list of identification numbers of the capacitive elements 21 detected as exceeding the threshold by the detection unit 2 as shown in FIGS. 3B to 3D in the storage unit 11 as user characteristics. May be. As shown in FIGS. 4A to 4C, the detection unit 2 may store the tap time of the user icon 22 in the storage unit 11 as a user characteristic.
The detection unit 2 acquires data based on an operation when the user normally uses the terminal device 1 after step S1, and adds the data to the data stored in the storage unit 11 in step S1 to characterize the user. The data shown may be updated.
　その後、ユーザは、特に意識することなく、端末装置１を通常通りに使用する。このとき、検出部２はユーザ操作により各静電容量素子２１に生じる静電容量を検出する（ステップＳ２）。 Thereafter, the user uses the terminal device 1 as usual without any particular attention. At this time, the detection part 2 detects the electrostatic capacitance which arises in each electrostatic capacitance element 21 by user operation (step S2).
　判定部３は、検出部２がユーザの通常の使用において検出する静電容量素子２１における静電容量の単位面積当たりの平均値の算出を所定回数行う。次に、判定部３は、所定回数分の静電容量の単位面積当たりの平均値の平均値を算出する。判定部３は、算出された平均値を現在のユーザ操作の特徴に設定する（ステップＳ３）。 The determination unit 3 calculates the average value per unit area of the capacitance in the capacitance element 21 detected by the detection unit 2 during normal use by the user a predetermined number of times. Next, the determination unit 3 calculates an average value of the average value per unit area of the electrostatic capacity for a predetermined number of times. The determination unit 3 sets the calculated average value as a feature of the current user operation (step S3).
　判定部３は、学習時における各ユーザの操作の特徴を記憶部１１から読み出す（ステップＳ１４）。そして、判定部３は、ステップＳ３で算出したユーザの操作の特徴と学習時における各ユーザの操作の特徴とを比較する。具体例として、現在のユーザ操作の特徴が、図３Ｃで示すように操作領域Ｅの面積が小さいことである場合について説明する。この場合、判定部３は、操作領域Ｅの面積が小さいため、現在使用しているユーザがユーザの属性が大人ではなく子供であると判定する（ステップＳ１５）。 The determination unit 3 reads out the feature of each user's operation during learning from the storage unit 11 (step S14). Then, the determination unit 3 compares the user operation characteristics calculated in step S3 with the user operation characteristics during learning. As a specific example, the case where the feature of the current user operation is that the area of the operation region E is small as shown in FIG. 3C will be described. In this case, since the area of the operation region E is small, the determination unit 3 determines that the currently used user is not an adult but a child (step S15).
　判定部３によってユーザを子供であると判定されたことに応じて、変更部４は、端末装置１において利用可能なメニューを制限する。例えば、変更部４は、課金などが発生する可能性がある機能を利用できないように端末装置１の機能を制限する（ステップＳ１６）。 In response to determining that the user is a child by the determination unit 3, the changing unit 4 restricts menus that can be used in the terminal device 1. For example, the changing unit 4 restricts the function of the terminal device 1 so that a function that may be charged may not be used (step S16).
　端末装置１に利用制限を掛ける機能は、課金が発生する機能以外に、電話やメッセージなどの発信機能、データの削除機能、データの編集機能、ウェブアクセス機能を含んでもよい。
　判定部３が判定するユーザの属性は、大人と子供に限定されない。ユーザの属性は、男性と女性であってもよい。ユーザの属性は、記憶部１１にデータが登録されているユーザと記憶部１１にデータが登録されていないユーザであってもよい。変更部４は、端末装置１の機能を各ユーザの属性に応じた機能に設定してもよい。 The function for restricting the use of the terminal device 1 may include a call function such as a telephone call or a message, a data deletion function, a data editing function, and a web access function, in addition to a function for generating a charge.
The attribute of the user determined by the determination unit 3 is not limited to adults and children. User attributes may be male and female. The user attributes may be a user whose data is registered in the storage unit 11 and a user whose data is not registered in the storage unit 11. The changing unit 4 may set the function of the terminal device 1 to a function corresponding to the attribute of each user.
　以上、第三の実施形態による端末装置１の処理フローについて説明した。上述の端末装置１の処理によれば、端末装置１は、ユーザの属性を判定し、その属性にあった設定を提供することで、課金などのトラブルを事前に防ぐことができる。 The processing flow of the terminal device 1 according to the third embodiment has been described above. According to the processing of the terminal device 1 described above, the terminal device 1 can prevent troubles such as billing in advance by determining the attribute of the user and providing the setting according to the attribute.
＜第四の実施形態＞
　図１０は、本発明の第四の実施形態による表示部６に表示される文字入力画面Ｕの例を示す。
　図１０の（ａ）部は、文字入力領域Ｔが拡大される前（通常時）の文字入力画面Ｕを示している。図１０の（ｂ）部は、文字入力領域Ｔが拡大された後の文字入力画面Ｕを示している。
　判定部３は、ユーザが文字入力の操作が困難な状態にあると判断した場合に、変更部４は、ユーザの文字入力を容易にするために、表示部６に図１０の（ｂ）部に示す文字入力画面Ｕを表示部６に表示する。 <Fourth embodiment>
FIG. 10 shows an example of a character input screen U displayed on the display unit 6 according to the fourth embodiment of the present invention.
Part (a) of FIG. 10 shows a character input screen U before the character input area T is enlarged (normal time). Part (b) of FIG. 10 shows the character input screen U after the character input area T is enlarged.
When the determination unit 3 determines that the user is in a state where it is difficult to input characters, the change unit 4 displays the (b) portion of FIG. 10 on the display unit 6 in order to facilitate the user's character input. The character input screen U shown in FIG.
　判定部３は、検出部２が検出するユーザの入力部（タッチパネル）５へのタップの時間間隔やユーザが実際にタップする領域などから、ユーザの文字入力の困難度を判定する。
　例えば、判定部３は、検出部２が検出するユーザの入力部（タッチパネル）５へのタップの時間間隔が長い場合にユーザの文字入力の操作が困難であると判断してもよい。判定部３は、検出部２がしきい値を超えたと検出した静電容量素子２１（文字入力領域Ｔにおける静電容量素子２１）の数が所定数を超えた場合にユーザの文字入力の操作が困難であると判断してもよい。 The determination unit 3 determines the degree of difficulty of the user's character input from the time interval of the tap on the user input unit (touch panel) 5 detected by the detection unit 2 or the region where the user actually taps.
For example, the determination unit 3 may determine that it is difficult for the user to perform a character input operation when the time interval between taps on the user input unit (touch panel) 5 detected by the detection unit 2 is long. The determination unit 3 performs a character input operation by the user when the number of the capacitive elements 21 (the capacitive elements 21 in the character input area T) that the detection unit 2 has detected exceeds the threshold value exceeds a predetermined number. May be determined to be difficult.
　ユーザの文字入力の操作が困難な状態にあると判定部３が判断した場合、変更部４は、図１０の（ｂ）部に示したように、文字入力領域Ｔを拡大する。その結果、現在の設定がユーザが文字を入力しやすい設定に変更される。
　文字入力領域Ｔの拡大表示は、文字入力領域Ｔの拡大だけでなく、文字入力画面Ｕのその他の部分の画像の変更も含む。 When the determination unit 3 determines that the user's character input operation is difficult, the change unit 4 enlarges the character input area T as illustrated in part (b) of FIG. As a result, the current setting is changed to a setting that allows the user to easily input characters.
The enlarged display of the character input area T includes not only the enlargement of the character input area T but also the change of the image of the other part of the character input screen U.
　図１１は、本発明の第四の実施形態による端末装置１の処理フローを示す図である。 FIG. 11 is a diagram showing a processing flow of the terminal device 1 according to the fourth embodiment of the present invention.
　第四の実施形態による判定部３は、検出部２が検出するユーザの入力部５へ行う操作によって静電容量素子２１に生じる静電容量に基づき文字入力の困難度を判定する点で第一の実施形態と異なる。
　第四の実施形態による変更部４は、判定部３が判定した判定結果に基づいて、表示部６における文字入力領域Ｔの大きさを変更する点で第一の実施形態と異なる。 The determination unit 3 according to the fourth embodiment is first in that it determines the difficulty of character input based on the capacitance generated in the capacitance element 21 by the operation performed on the input unit 5 of the user detected by the detection unit 2. Different from the embodiment.
The changing unit 4 according to the fourth embodiment is different from the first embodiment in that the size of the character input area T in the display unit 6 is changed based on the determination result determined by the determining unit 3.
　次に、第四の実施形態による端末装置１の処理フローを説明する。
　この実施形態による端末装置１の処理フローは、端末装置１が、ユーザの文字入力画面Ｕにおいて行う操作からユーザの文字入力の困難度を判定する場合の例である。
　第四の実施形態による端末装置１の処理フローは、ステップＳ１７とステップＳ１８の処理を行い、次に、第一の実施形態によるステップＳ３～ステップＳ８の処理を行う。 Next, a processing flow of the terminal device 1 according to the fourth embodiment will be described.
The processing flow of the terminal device 1 according to this embodiment is an example of the case where the terminal device 1 determines the degree of difficulty of user character input from an operation performed on the user character input screen U.
The processing flow of the terminal device 1 according to the fourth embodiment performs the processes of step S17 and step S18, and then performs the processes of step S3 to step S8 according to the first embodiment.
　ユーザは、まず、例えば自身の文字入力操作の特徴を端末装置１に学習させる。具体的には、ユーザは、文字入力領域Ｔに対する文字入力操作を繰り返し行う。
　検出部２は、ユーザの文字入力操作による例えば文字入力のタップ操作から次のタップ操作までの時間を検出し、検出した時間をユーザの特徴として記憶部１１に記憶する（ステップＳ１７）。ステップＳ１７の処理は、各ユーザについて行う。 The user first causes the terminal device 1 to learn the characteristics of his / her character input operation, for example. Specifically, the user repeatedly performs a character input operation on the character input area T.
The detection unit 2 detects a time from, for example, a character input tap operation by the user's character input operation to the next tap operation, and stores the detected time in the storage unit 11 as a user characteristic (step S17). The process of step S17 is performed for each user.
　その後、ユーザは、特に意識することなく、文字入力領域Ｔに対して通常通りに文字入力操作をする。このとき、検出部２はこの通常の使用においてユーザ操作から文字入力のタップ操作から次のタップ操作までの時間を検出する（ステップＳ１８）。 After that, the user performs a character input operation as usual in the character input area T without being particularly conscious. At this time, the detection unit 2 detects the time from the user operation to the character input tap operation to the next tap operation in this normal use (step S18).
　判定部３は、検出部２がユーザの通常の使用において検出する静電容量素子２１における静電容量の単位面積当たりの平均値の算出を所定回数行う。次に、判定部３は、所定回数分の静電容量の単位面積当たりの平均値を統計値として算出する。判定部３は、統計値として算出された平均値を（以下において、通常の使用時におけるユーザの平均値と称する場合がある）現在のユーザ操作の特徴に設定する（ステップＳ３）。 The determination unit 3 calculates the average value per unit area of the capacitance in the capacitance element 21 detected by the detection unit 2 during normal use by the user a predetermined number of times. Next, the determination unit 3 calculates an average value per unit area of the electrostatic capacity for a predetermined number of times as a statistical value. The determination unit 3 sets the average value calculated as the statistical value as a feature of the current user operation (hereinafter, may be referred to as a user average value during normal use) (step S3).
　判定部３は、学習時における各ユーザの操作の特徴を示す静電容量の単位面積当たりの平均値（以下において、学習時における各ユーザの平均値と称する場合がある）を記憶部１１から読み出す（ステップＳ４）。 The determination unit 3 reads from the storage unit 11 an average value per unit area of capacitance indicating characteristics of each user's operation at the time of learning (hereinafter may be referred to as an average value of each user at the time of learning). (Step S4).
　判定部３は、通常の使用時におけるユーザの平均値と、学習時における各ユーザの平均値とを比較する（ステップＳ５）。 The determination unit 3 compares the average value of the user during normal use with the average value of each user during learning (step S5).
　判定部３は、現在のユーザ操作の特徴（例えば、通常の使用時におけるユーザのタップ操作の間隔）と記憶部１１から読み出したユーザ操作の特徴（例えば、学習時における各ユーザのタップ操作の間隔）とを比較する（ステップＳ６）。 The determination unit 3 uses the current user operation characteristics (for example, the interval between user tap operations during normal use) and the user operation feature read from the storage unit 11 (for example, the interval between tap operations for each user during learning). ) Is compared (step S6).
　判定部３は、ステップＳ５とステップＳ６とにおける比較結果に基づいて、現在使用しているユーザの特徴と最も近い特徴のユーザが現在使用しているユーザであると特定する（ステップＳ７）。
　判定部３は、ステップＳ５またはステップＳ６の何れか１つのステップに基づいて現在使用しているユーザを特定してもよい。 Based on the comparison result in step S5 and step S6, the determination unit 3 specifies that the user having the closest feature to the feature of the currently used user is the user currently using (step S7).
The determination unit 3 may specify the user currently in use based on any one of step S5 and step S6.
　判定部３がユーザを特定すると、端末装置１の変更部４は、ユーザが利用メニューに応じて予め記憶部１１に記憶した端末装置１の利用しやすい設定を読み出し、端末装置１の設定を読み出した設定に変更する（ステップＳ８）。
　この変更部４による変更は、例えば、背景画像、アイコンの配置、利用できる機能などである。
　この処理フローのステップＳ３～ステップＳ８における“操作”とは、“文字入力操作”のことである。
　上記の処理の代わりに、判定部３は、ステップＳ３で取得した現在のユーザ操作の特徴（例えば、通常の使用時におけるユーザのタップ操作の間隔や、検出部２がしきい値を超えたと検出した静電容量素子２１の数）に基づいて、ユーザが文字入力の操作が困難であるか否かを判断してもよい。また、変更部４は、判定部３の判断結果に応じて、端末装置１の設定を変更してもよい。 When the determination unit 3 identifies the user, the changing unit 4 of the terminal device 1 reads the user-friendly settings of the terminal device 1 stored in the storage unit 11 in advance according to the usage menu, and reads the settings of the terminal device 1. The setting is changed (step S8).
The change by the change unit 4 is, for example, a background image, icon arrangement, usable functions, and the like.
The “operation” in step S3 to step S8 of this processing flow is a “character input operation”.
Instead of the above processing, the determination unit 3 detects the characteristics of the current user operation acquired in step S3 (for example, the interval between the tap operations of the user during normal use and the detection unit 2 exceeding the threshold value). Based on the number of capacitance elements 21 that have been made, it may be determined whether or not the user has difficulty in inputting characters. The changing unit 4 may change the setting of the terminal device 1 according to the determination result of the determining unit 3.
　以上、第四の実施形態による端末装置１の処理フローについて説明した。上述の端末装置１によれば、判定部３は、ユーザの入力部（タッチパネル）５へのタップの時間間隔や静電容量がしきい値を超えた文字入力領域Ｔにおける静電容量素子２１の数に基づいてユーザの文字入力の困難度を判定する。変更部４は、その困難度にあった文字入力設定を提供する。その結果、ユーザにとって端末装置１の利便性が向上する。 The processing flow of the terminal device 1 according to the fourth embodiment has been described above. According to the terminal device 1 described above, the determination unit 3 determines the capacitance element 21 in the character input region T in which the tap time interval or capacitance of the user input unit (touch panel) 5 exceeds the threshold value. The difficulty level of the user's character input is determined based on the number. The changing unit 4 provides a character input setting suitable for the degree of difficulty. As a result, the convenience of the terminal device 1 is improved for the user.
＜第五の実施形態＞
　図１２は、本発明の第五の実施形態による端末装置１の処理フローを示す図である。
　第五の実施形態による端末装置１は、図２で示した第一の実施形態の端末装置１と同様に、検出部２と、判定部３と、変更部４と、入力部５と、表示部６と、記憶部１１とを備える。 <Fifth embodiment>
FIG. 12 is a diagram showing a processing flow of the terminal device 1 according to the fifth embodiment of the present invention.
The terminal device 1 according to the fifth embodiment is similar to the terminal device 1 of the first embodiment shown in FIG. 2, and includes a detection unit 2, a determination unit 3, a change unit 4, an input unit 5, and a display. Unit 6 and storage unit 11.
　第五の実施形態による端末装置１の処理フローは、１つの端末装置１に対して複数のユーザ各々の操作を判定する点で第一の実施形態と異なる。
　第五の実施形態による変更部４は、判定部３の判定に基づいてユーザ毎に操作環境を設定する点で第一の実施形態と異なる。 The processing flow of the terminal device 1 according to the fifth embodiment differs from the first embodiment in that the operation of each of a plurality of users is determined for one terminal device 1.
The changing unit 4 according to the fifth embodiment is different from the first embodiment in that the operating environment is set for each user based on the determination of the determining unit 3.
　次に、第五の実施形態による端末装置１の処理フローを説明する。
　この実施形態による処理フローは、端末装置１が、ユーザＡとユーザＢとがサッカー対戦ゲーム上の選手を表すアイコンをタップする特徴からユーザを特定する場合の例である。 Next, a processing flow of the terminal device 1 according to the fifth embodiment will be described.
The processing flow according to this embodiment is an example in the case where the terminal device 1 specifies a user from the feature that the user A and the user B tap an icon representing a player on the soccer match game.
　各ユーザは、まず、選手を表すアイコンのタップなどのゲームに必要な操作の特徴を端末装置１に学習させる。具体的には、各ユーザは、端末装置１に対して選手を表すアイコンのタップ操作を繰り返し行う。
　検出部２は、各ユーザのこのアイコンのタップ操作による静電容量の平均値（および平均値の変移）を、各ユーザの特徴として記憶部１１に記憶する（ステップＳ１９）。端末装置１が行うこの学習は、ユーザ毎に独立して行う。
　検出部２は、例えば、図３Ａ～３Ｄで示したような検出部２によって静電容量がしきい値を超えたと検出された静電容量素子２１の識別番号のリストを各ユーザの特徴として記憶部１１に記憶してもよい。検出部２は、図４Ａ～４Ｃで示すような各ユーザの選手を表すアイコンのタップ時間を各ユーザの特徴として記憶部１１に記憶してもよい。 Each user first causes the terminal device 1 to learn the operation features necessary for a game such as taps on icons representing players. Specifically, each user repeatedly performs a tap operation on an icon representing a player on the terminal device 1.
The detection part 2 memorize | stores the average value (and change of average value) of the electrostatic capacitance by tap operation of this icon of each user in the memory | storage part 11 as a characteristic of each user (step S19). This learning performed by the terminal device 1 is performed independently for each user.
The detection unit 2 stores, for example, a list of identification numbers of the capacitive elements 21 detected by the detection unit 2 as shown in FIGS. 3A to 3D that the electrostatic capacitance has exceeded a threshold value as features of each user. You may memorize | store in the part 11. FIG. The detection unit 2 may store the tap time of an icon representing each user's player as shown in FIGS. 4A to 4C in the storage unit 11 as a feature of each user.
　その後、各ユーザは、特に意識することなく、端末装置１を共有して使用する。ユーザＡとユーザＢは各自が操作する対戦ゲームのキャラクタを操作する。このとき、検出部２はユーザ操作により各静電容量素子２１に生じる静電容量を検出する（ステップＳ２０）。 Thereafter, each user shares and uses the terminal device 1 without being particularly conscious. User A and user B operate the character of the battle game that they operate. At this time, the detection part 2 detects the electrostatic capacitance which arises in each electrostatic capacitance element 21 by user operation (step S20).
　判定部３は、検出部２が各ユーザの操作すべき選手を表すアイコン操作において静電容量素子２１における静電容量の単位面積当たりの平均値の算出を所定回数行う。次に、判定部３は、所定回数分の静電容量の単位面積当たりの平均値の平均値を統計値として算出する。判定部３は、統計値として算出された平均値（以下において、通常の使用時における各ユーザの平均値と称する場合がある）を現在の各ユーザ操作の特徴に設定する（ステップＳ２１）。 The determination unit 3 calculates the average value per unit area of the capacitance in the capacitance element 21 a predetermined number of times when the detection unit 2 performs an icon operation representing a player to be operated by each user. Next, the determination unit 3 calculates an average value of the average value per unit area of the electrostatic capacity for a predetermined number of times as a statistical value. The determination unit 3 sets an average value calculated as a statistical value (hereinafter may be referred to as an average value of each user during normal use) as a feature of each current user operation (step S21).
　判定部３は、学習時における各ユーザの操作の特徴を示す静電容量の単位面積当たりの平均値（以下において、学習時における各ユーザの平均値と称する場合がある）を記憶部１１から読み出す（ステップＳ２２）。 The determination unit 3 reads from the storage unit 11 an average value per unit area of capacitance indicating characteristics of each user's operation at the time of learning (hereinafter may be referred to as an average value of each user at the time of learning). (Step S22).
　判定部３は、通常の使用時における各ユーザの平均値と、学習時における各ユーザの平均値とを比較する（ステップＳ２３）。 The determination unit 3 compares the average value of each user during normal use with the average value of each user during learning (step S23).
　判定部３は、検出部２が検出する複数のユーザが各自の操作する選手を表すアイコンに対して行う操作によって生じる操作特徴に基づき、ステップＳ５～ステップＳ７と同様に各ユーザの操作を判定する（ステップＳ２４）。 The determination unit 3 determines the operation of each user in the same manner as in Steps S5 to S7, based on operation characteristics generated by operations performed by the plurality of users detected by the detection unit 2 on the icons representing the players operated by the respective users. (Step S24).
　変更部４は、判定部３の判定結果に基づいてサッカー対戦ゲームの選手のアイコンを操作すべきユーザのみが操作可能となるようにユーザ毎に操作環境を設定する（ステップＳ２５）。
　例えば、上述のサッカー対戦ゲームにおいて、ユーザＡが操作すべき選手のアイコンが、Ａ１～Ａ１１であると仮定する。また、上述のサッカー対戦ゲームにおいて、ユーザＢが操作すべき選手のアイコンが、Ｂ１～Ｂ１１であると仮定する。
　この場合、上述のステップＳ１９からステップＳ２３の処理に続き、ステップＳ２４の判定を行う。ステップＳ２４の判定結果に基づいて、ステップＳ２５でユーザ毎に操作環境を設定する。この設定により、ユーザＡはＡ１～Ａ１１の選手のアイコンのみを操作でき、ユーザＢはＢ１～Ｂ１１の選手のアイコンのみ操作できるようになる。 The changing unit 4 sets the operating environment for each user so that only the user who should operate the icon of the player of the soccer match game can operate based on the determination result of the determining unit 3 (step S25).
For example, in the above-described soccer match game, it is assumed that the icons of the players to be operated by the user A are A1 to A11. Further, it is assumed that the icons of the players to be operated by the user B are B1 to B11 in the above-described soccer battle game.
In this case, the determination in step S24 is performed following the processing from step S19 to step S23 described above. Based on the determination result of step S24, an operation environment is set for each user in step S25. With this setting, the user A can operate only the icons of the players A1 to A11, and the user B can operate only the icons of the players B1 to B11.
　以上、第五の実施形態による端末装置１の処理フローについて説明した。上述の端末装置１によれば、判定部３は、各ユーザの操作の特徴を判定する。変更部４は、各ユーザの操作対象を設定する。その結果、複数のユーザの操作が互いに干渉することがなく同時に操作が可能となる環境をユーザに提供する。 The processing flow of the terminal device 1 according to the fifth embodiment has been described above. According to the terminal device 1 described above, the determination unit 3 determines the feature of each user's operation. The changing unit 4 sets the operation target of each user. As a result, an environment in which operations of a plurality of users can be performed simultaneously without interfering with each other is provided to the user.
