Abstract
Description
前記端末の一方の面に設けられ、指タッピング運動に関連する情報を表示可能であるとともに、前記端末を保持するユーザの同じ手の2本の指の一方によりタッピングされるタッチパネルと、
前記タッチパネルをタッピングする前記一方の指の動きを検出する指検出部と、
前記指検出部で得られた検出情報に基づき、前記タッチパネルと反対側に位置される前記端末の他方の面を保持する前記2本の指の他方と、前記タッチパネルをタッピングする前記一方の指との間の指タッピング運動時の二指間距離を計測する処理を行なう処理部と、
を有することを特徴とする。
なお、以下に示される本発明の一実施の形態に係る指タッピング計測処理端末は、タッチパネルを利用して指タッピング運動を計測処理できる端末として構成され、図12に示されるように、通信手段(ネットワーク)を介してサーバ1203に接続される使用形態(これについては後述する)も考えられるが、どのような使用形態をとっても構わない。また、指タッピング計測処理端末は、本実施の形態では、スマートフォンのような小型端末として構成されるが、タブレット型の薄型コンピュータや、パーソナルコンピュータ等のような形態を成していても構わない。
図2は、指タッピング計測処理端末100を掴んでいる左手の周辺部分の断面を示しているが、指タッピング計測処理端末100を掴んでいる右手の周辺部分の断面も同様である。図2において、指タッピング計測処理端末100は、タッチパネル103、表示ユニット部201、感圧センサ202をディスプレイを成す表面側に有し、感圧センサ203を裏面側に有し、また、カメラ101と同じ側の縁部に加速度センサ204、固定治具205をさらに有している。表示ユニット部201は、液晶などで構成され、透明性の高いタッチパネル103を介して表示内容を表示するものである。また、感圧センサ202,203は、タッピングする人差し指113(123)がタッチパネル103の表面に接触する際の接触圧(押圧)を感知するものであり、加速度センサ204は、単位時間当たりの速度の変化である加速度を検出するセンサであり、動き・振動・衝撃などを捉えることができる。また、加速度のみならず、速度や回転の方向を検出するセンサも備える。固定治具205は、指タッピング計測処理端末100を保持して支える親指112(142)を固定する治具であり、端末100の裏面に対して親指112(142)を接触させた状態で固定する。
図3は、カメラ101でタッピング運動を行う人差し指113,123を撮影するときの状態を示した断面図である。図4は、目標長治具401を用いて、指タッピング計測処理端末100の表面から人差し指113を目標間隔距離(二指間目標距離)だけ開いた状態に設定し、カメラ101で目標間隔距離に開いた状態の人差し指113を撮影することを説明する図である。図5は、図4に示された状態で生じた目標長治具401と人差し指113(115)との接触面により指113(115)がへこむ(変形する)際の補正について説明する図である。図6は、端末100が2画面を有する場合、2画面を用いて、人差し指113,123を指タッピング計測処理端末100の表面から目標間隔距離だけ開いた状態に設定し、カメラ101で目標間隔距離に開いた状態の人差し指113,123を撮影することを説明する図である。なお、図3、図4、図5、図6において、図1および図2と同一の部分については、図1および図2と同一の符号を付してその説明を省略する。
図8は、端末100の一辺側にカメラ101および測距センサ102を設け、対向する他の一辺側にもカメラ801および測距センサ802を設けた、指タッピング計測処理端末100を示している。なお、図8において、図1、図2、図3、図4、図5、図6、図7と同一の部分については、図1、図2、図3、図4、図5、図6、図7と同一の符号を付してその説明を省略する。
図10は、本実施の形態に係る指タッピング計測処理端末100末の動作を説明するフローチャートの例である。ここでは、図8の構成を前提としており、したがって、タッピング運動している指の動きをカメラ101,801で撮影して二指間距離を計測するか或いは測距センサ102,802で指の位置を検出して二指間距離を計測するかどうかが決定される(S1001)。カメラ101,801でタッピング運動の指の動きを撮影する場合には、タッピング運動を行なう指の撮影の前に、端末100上で指を所定の目標距離に開いた状態に設定し(S1002)、この状態で指をカメラ101,108で撮影し、撮影した画像から指タッピング運動中の撮影画像の距離基準を取得する。また、ユーザは所定の目標距離に開いた指の設定状態を認識する。よって、ユーザにとってタッピング運動を行なう際に目標距離で開くように意識付けすることが可能となる(S1003)。カメラによる事前撮影の後、ユーザは計測のためのタッピング運動に入る(あるいは、コンピュータプログラムによりタッピング動作を促される)(S1004)。一方、測距センサ102,802で指の位置を検出する場合には、検出前に予め、二指間距離計測のために指を所定の目標距離に開いた状態に設定する必要はなく、そのままユーザは計測のためのタッピング運動に入る(S1004)。なお、測距センサ102、802による検出の場合でも、指を所定目標間隔距離に開いた状態に設定することにより、ユーザにとってタッピング運動を行なう際に目標距離で開くように意識付けすることが可能となる。もちろん、測距センサを用いる場合にも、S1002,1003のようなステップで較正しても良い。
図12は、指タッピング計測処理端末100、ヘッドマウント報処理装置1201、サーバ装置1203により構成される指タッピング計測処理システムの一実施例を示している。
