以下、図面を参照しながら、本発明に係る携帯端末の実施形態について説明する。   Hereinafter, embodiments of a portable terminal according to the present invention will be described with reference to the drawings.

図１に本実施形態における携帯端末１０の外観構成を示す。同図に示すように、携帯端末１０の把持部位１８には、複数の圧電素子が付されており、当該部位に加えられた圧力を検知できるようになっている。また、図１の所定部位１９は、携帯端末１０が把持部位１８で握られたとき、握られた状態で近くの物（机等）の平面に接触させやすい部分に位置している。また、所定部位１９にも、圧電素子が付されており、当該部位に加えられた圧力を検知できるようになっている。携帯端末１０として、具体的には例えば、ＰＤＡ（Personal Digital Assistants）や図１に示すような携帯電話等が相当する。   FIG. 1 shows an external configuration of a mobile terminal 10 in the present embodiment. As shown in the figure, the gripping portion 18 of the mobile terminal 10 is provided with a plurality of piezoelectric elements so that the pressure applied to the portion can be detected. Further, the predetermined portion 19 in FIG. 1 is located at a portion where the portable terminal 10 is easily held in contact with a plane of a nearby object (desk or the like) when the portable terminal 10 is held by the holding portion 18. In addition, a piezoelectric element is also attached to the predetermined portion 19 so that the pressure applied to the portion can be detected. Specifically, the mobile terminal 10 corresponds to, for example, a PDA (Personal Digital Assistants), a mobile phone as shown in FIG.

図２に示すように、携帯端末１０は、圧力分布検出部１２と、割当情報保持部１３と、情報選択部１４と、情報確定部１５とを備える。   As shown in FIG. 2, the mobile terminal 10 includes a pressure distribution detection unit 12, an allocation information holding unit 13, an information selection unit 14, and an information determination unit 15.

圧力分布検出部１２は、把持部位１８に付されている複数の圧電素子により把持部位１８の圧力分布を検出する。また、所定部位１９に付されている圧電素子により所定部位１９の圧力分布を検出する。圧力分布検出部１２の機能は、具体的には、例えば図３に示すように、増幅回路１２ａと、信号処理回路１２ｂとを含んだ構成により実現される。具体的な検出方法は後述する。   The pressure distribution detection unit 12 detects the pressure distribution in the gripping part 18 by using a plurality of piezoelectric elements attached to the gripping part 18. Further, the pressure distribution of the predetermined portion 19 is detected by a piezoelectric element attached to the predetermined portion 19. Specifically, the function of the pressure distribution detection unit 12 is realized by a configuration including an amplifier circuit 12a and a signal processing circuit 12b, for example, as shown in FIG. A specific detection method will be described later.

割当情報保持部１３は、把持部位１８の圧力分布に応じた、入力される情報の各々の割り当て情報を保持する。当該保持は、例えば、図４に示す各圧電素子１８ａ，１８ｂ等に加えられた圧力からなる圧力分布に「カメラ」機能が対応しているという情報をテーブル等で保持しておくことにより行われる。   The allocation information holding unit 13 holds allocation information for each piece of input information corresponding to the pressure distribution of the grasped part 18. The holding is performed, for example, by holding information that the “camera” function corresponds to the pressure distribution made up of the pressure applied to each piezoelectric element 18a, 18b, etc. shown in FIG. .

情報選択部１４は、圧力分布検出部１２により検出された把持部位１８の圧力分布と、割当情報保持部１３に保持される情報とに基づいて、入力される情報を選択する。情報確定部１５は、情報選択部１４により入力される情報が選択された後、圧力分布検出部１２により検出された所定部位１９の圧力分布に基づいて、選択された情報を入力される情報として確定する。   The information selection unit 14 selects input information based on the pressure distribution of the grasped part 18 detected by the pressure distribution detection unit 12 and the information held in the allocation information holding unit 13. After the information input by the information selection unit 14 is selected, the information determination unit 15 selects the selected information as input information based on the pressure distribution of the predetermined portion 19 detected by the pressure distribution detection unit 12. Determine.

以下、図５のフローチャートを用いて、本実施形態における携帯端末１０により実行される処理を説明する。   Hereinafter, processing executed by the mobile terminal 10 in the present embodiment will be described using the flowchart of FIG.

まず、携帯端末１０の把持部位１８が、使用者により把持され、使用者が入力しようとする情報に対応した圧力分布が発生するように加圧される（Ｓ０１）。   First, the gripping portion 18 of the mobile terminal 10 is gripped by the user and pressurized so that a pressure distribution corresponding to information to be input by the user is generated (S01).

続いて、圧力分布検出部１２が、把持部位１８の部分に付された複数の圧電素子により圧力分布を検出する（Ｓ０２）。図３に示す構成から、具体的には次のように検出する。まず、加圧された圧電素子からアナログの電気信号が発生する。続いて、増幅回路１２ａが、発生した電気信号を信号処理できる大きさに増幅する。続いて、信号処理回路１２ｂが、増幅された信号を圧力分布としてデジタル信号に変換する。変換されたデジタル信号は、アプリケーション制御装置に送られ、以下の機能が実現される。   Subsequently, the pressure distribution detection unit 12 detects the pressure distribution using a plurality of piezoelectric elements attached to the gripping portion 18 (S02). Specifically, detection is performed as follows from the configuration shown in FIG. First, an analog electric signal is generated from the pressurized piezoelectric element. Subsequently, the amplifier circuit 12a amplifies the generated electric signal to a size that allows signal processing. Subsequently, the signal processing circuit 12b converts the amplified signal into a digital signal as a pressure distribution. The converted digital signal is sent to the application control apparatus, and the following functions are realized.

圧力分布が検出されると、情報選択部１４が、把持部位１８の圧力分布と、割当情報保持部１３により保持されている割当情報とに基づいて、入力される情報を選択する（Ｓ０３）。例えば、図４に示すような圧力分布である場合は、「カメラ」機能が選択される。   When the pressure distribution is detected, the information selection unit 14 selects information to be input based on the pressure distribution of the grasped part 18 and the allocation information held by the allocation information holding unit 13 (S03). For example, when the pressure distribution is as shown in FIG. 4, the “camera” function is selected.

ここで、選択された情報を確定させるために、所定部位１９が、利用者により加圧される（Ｓ０４）。所定部位１９への圧力の付加は、例えば近くの物の平面等に所定部位１９を接触させることにより行われる。なお、情報の確定のための操作の前に、再度、情報の選択のための操作（Ｓ０１）を行ってもよい。また、上記接触させるものは平面に限らず、圧力が加えられるものであればよい。   Here, in order to confirm the selected information, the predetermined part 19 is pressurized by the user (S04). The application of pressure to the predetermined portion 19 is performed by bringing the predetermined portion 19 into contact with a plane of a nearby object, for example. Note that the operation for selecting information (S01) may be performed again before the operation for confirming the information. Moreover, what is contacted is not limited to a flat surface, but may be anything as long as pressure is applied.

続いて、圧力分布検出部１２が、所定部位１９の部分に付された圧電素子により圧力分布を検出する（Ｓ０５）。   Subsequently, the pressure distribution detector 12 detects the pressure distribution by the piezoelectric element attached to the predetermined portion 19 (S05).

続いて、情報確定部１５が、検出された所定部位１９の圧力分布に基づいて、選択された情報を入力される情報として確定する（Ｓ０６）。なお、所定部位１９の圧力分布は、情報の確定のみに必要であるので、圧力が加えられたことが検出できるものであればよい。   Subsequently, the information confirmation unit 15 confirms the selected information as input information based on the detected pressure distribution of the predetermined portion 19 (S06). Note that the pressure distribution at the predetermined portion 19 is necessary only for confirmation of information, and therefore, any pressure can be detected as long as it can be detected.

上記により、本実施形態によれば、入力する情報の選択は端末の把持により、情報の確定は別の部位における圧力の付加により行うことにより、操作性がより優れた携帯端末１０を実現することができる。   As described above, according to the present embodiment, the selection of information to be input is performed by grasping the terminal, and the determination of information is performed by applying pressure in another part, thereby realizing the mobile terminal 10 with better operability. Can do.

なお、本実施形態では、圧力分布に応じて入力される情報が選択される場合を示したが、当該圧力分布の時間的変化を入力させる情報に対応させてもよい。圧力分布の時間的変化は、圧力分布検出部１２により検出された圧力分布の時系列データから求めることができる。   In the present embodiment, the case where the information to be input is selected according to the pressure distribution has been described. However, the information may be associated with information for inputting a temporal change in the pressure distribution. The temporal change of the pressure distribution can be obtained from the time series data of the pressure distribution detected by the pressure distribution detector 12.

また、本実施形態においては、圧力の検出を圧電素子で行うこととしているが、圧電フィルムを用いてもよいし、プッシュスイッチ等を用いてもよい。   In this embodiment, the pressure is detected by a piezoelectric element, but a piezoelectric film may be used, or a push switch or the like may be used.

また、本実施形態においては、入力される情報は携帯端末１０に備えられた機能の選択としたが、例えば文字等の入力、テレビ又はラジオのボリュームの調節、並びに表示画像又は音声の調節等、様々な情報の入力に応用が可能である。   In the present embodiment, the input information is a selection of a function provided in the mobile terminal 10, but for example, input of characters or the like, adjustment of the volume of a television or radio, adjustment of a display image or sound, etc. It can be applied to input various information.
