May be displayed. Furthermore, the criterion for selecting an icon may be that the position of the finger H5 in the real space and the position of the icon in the virtual space satisfy a predetermined relationship.

- the icon of the element 823 is returned to the position where it is completely surrounded by the selection determination display 823b.
- the icon of the selection element 823 behaves as if it is fixed at the original position by a spring having the maximum deflection corresponding to the predetermined distance.
- Such behavior can be generated by defining a virtual spring using physical factors including a spring constant.
- the amount of maximum deflection of the virtual spring can be defined according to the amount of shake assumed for the finger H5. For example, when the operator moves such as walking (that is, in the movement mode), the operator moves. It can be defined assuming that it is larger than the case where it is not (that is, the normal mode).
- the mode in which the tracking starts when the selection of the icon of the selection element 823 is determined that is, when the icon of the selection element 823 is completely surrounded by the selection determination display 823b has been described.
- This aspect is preferable from the viewpoint of preventing erroneous operation of the icon.

図1は、一実施の形態にかかる眼鏡表示装置100の基本構成の一例を示す模式的外観正面図であり、図2は、眼鏡表示装置100の一例を示す模式的外観斜視図である。
図1および図2に示すように、眼鏡ユニット200は、眼鏡フレーム210および一対の半透過ディスプレイ220からなる。眼鏡フレーム210は、主にリムユニット211、テンプルユニット212を含む。
眼鏡フレーム210のリムユニット211により一対の半透過ディスプレイ220が支持される。
また、当該レンズ類の一部に、半透過ディスプレイ220を埋め込んで設けてもよい。
次に、通信システム300について説明を行なう。
通信システム300は、バッテリーユニット301、アンテナモジュール302、カメラユニット303、スピーカユニット304、GPS(Global Positioning System)ユニット307、マイクユニット308、SIM(Subscriber Identity Module Card)ユニット309およびメインユニット310を含む。
なお、カメラユニットにはCCDセンサが備えられてよい。スピーカユニット304は、ノーマルイヤホンであってもよいし、骨伝導イヤホンであってもよい。SIMユニット309には、NFC(Near Field Communication:近距離無線通信)ユニットおよび他の接触式ICカードユニット、ならびに非接触式ICカードユニットを含む。
したがって、ユーザは、眼鏡表示装置100を用いて、通信装置、スピーカおよびマイクにより、携帯電話と同様の通話機能を使用することができる。また、眼鏡型であるので、両手を利用せず、通話を行なうことができる。
続いて、操作システム400は、赤外線検知ユニット410、ジャイロセンサユニット420、加速度検知ユニット430および制御ユニット450からなる。赤外線検知ユニット410は、主に赤外線照射素子411および赤外線検知カメラ412からなる。

以上により、図5(a)に示すように、手のジェスチャを認識する。
これによって、図5(b)に示すように、たとえば写真アプリによる画像が表示される。この際、当該画面には、カメラユニット303からの撮像データが表示されてよい。

すなわち、実際には眼鏡表示装置100の半透過ディスプレイ220に表示されるものの、ユーザは、右目のイメージは右目側の半透過ディスプレイ220を透過し三次元空間領域2203DRで認識し、左目のイメージは左目側の半透過ディスプレイ220を透過し三次元空間領域2203DLで認識する。その結果、認識された両イメージがユーザの脳内で合成されることにより、仮想イメージ表示領域2203Dで仮想イメージとして認識することができる。
また、図8に示すように、一対の半透過ディスプレイ220よりも赤外線検知ユニット410が上方(y軸正方向)に配設されている場合について説明しているが、鉛直方向(y軸方向)に対して、赤外線検知ユニット410の配設位置が半透過ディスプレイ220よりも下方(y軸負方向)または半透過ディスプレイ220と同位置であっても、同様に、仮想イメージ表示領域2203Dは、三次元空間検知領域4103Dと共有する空間領域を有する。

また、キャリブレーション処理には、ユーザの個々で異なる指の長さ、手の長さ、腕の長さの調整も行なう。
すなわち、ユーザによりユーザの個々で異なる指の長さ、手の長さ、腕の長さが異なるので、操作領域410cの調整を行なうものである。
なお、ジェスチャ領域410gは、仮想イメージ表示領域2203Dと重ならないように配置しかつ深さ方向(z軸正方向)に厚みを持たせることが好ましい。
そのため、赤外線検知ユニット410からの信号を無処理のまま使用すると、ユーザは、手先が仮想イメージ表示領域2203Dから外れたとしても、そのような状態であることを体感しにくい。
その結果、ユーザは、両腕を最大限に伸ばした状態、または少し曲げた状態で、奥行きのある平面状の仮想イメージ表示領域2203D内の中央部から端部まで操作することができる。
続いて、半透過ディスプレイ220に、像の周囲を指で囲んでくださいと、表示を行なう(ステップS16)。ここで、像の近傍に指の形の像を薄く表示してもよいし、半透過ディスプレイ220に表示を行なう代わりにスピーカから音声により指示をユーザに伝えてもよい。
なお、上記においては、指で矩形を形作り、そのように定められた矩形と、像の外縁の矩形にあわせる。このことによって、指により定められた矩形の視認サイズおよび位置と像の外縁の矩形の視認サイズ及び位置とを合わせることとした。しかしながら、指によって形状を定める手法はこれに限定されず、表示された像の外縁を指でなぞる手法、表示された像の外縁上の複数の点を指で指し示す手法等、他の任意の手法であってもよい。また、これらの手法を複数のサイズの像について行ってもよい。
次いで、指認識について説明を行い、その後掌認識、腕認識の順で説明を行なう。図15は、指認識の一例を示す模式図である。図15において、(A)は指の先端付近の拡大図であり、(B)は指の根元付近の拡大図である。図16は、指認識の処理の一例を示すフローチャートである。
次に、赤外線検知ユニット410により画像データをピクセル単位で距離に置き換える(ステップS23)。この場合、赤外線の明るさは、距離の三乗に反比例する。これを利用し、デプスマップを作成する(ステップS24)。
続いて、二値化した画像データから約100個の頂点を持つポリゴンを作成する(ステップS26)。そして、頂点が滑らかになるようにローパスフィルタ(LPF)により、より多くの頂点pnを有する新たな多角形を作成することによって、図15に示す手の外形OFを抽出する(ステップS27)。
なお、本実施の形態においては、ステップS26において二値化したデータからポリゴンを作成するために抽出する頂点の数を約100個としているが、これに限定されず、1000個、その他の任意の個数であってもよい。
ステップS27で作成した新たな多角形の頂点pnの集合から、Convex Hullを用いて、凸包を抽出する(ステップS28)。
その後、ステップS27で作成された新たな多角形と、ステップS28で作成された凸包との共有の頂点p0を抽出する(ステップS29)。このように抽出された共有の頂点p0自体を指の先端点として用いることができる。
さらに、頂点p0の位置に基づいて算出される他の点を指の先端点として用いてもよい。例えば、図15(A)に示すように頂点p0における外形OFの内接円の中心を先端点P0として算出することもできる。
全ての指について同様の処理を行なうことで、全ての指のスケルトンを得る。これにより、手のポーズを認識することができる。すなわち、親指、人差し指、中指、薬指、小指のいずれの指が広げられ、いずれの指が握られているかを認識することができる。
グラフィック演算ユニット463は、キャリブレーションサービスユニット461を用いてキャリブレーションデータ記録ユニット457を参照し、表示の補正を行なう(ステップS36)。
最後に、ディスプレイ演算ユニット464により半透過ディスプレイ220に表示を行なう(ステップS37)。
次いで、図17は、掌認識の一例を示す模式図である。
次いで、腕認識について説明を行なう。本実施の形態において、腕認識は、指、掌および親指のいずれかを認識した後に実施する。なお、腕認識は、指、掌および親指のいずれかを認識する前、またはそれらの少なくともいずれかと同時に実施してもよい。
その後、抽出した外形に外接する四角枠を選定する。本実施の形態においては、当該四角枠は、平行四辺形または長方形からなる。
この場合、平行四辺形または長方形は、対向する長辺を有するので、長辺の延在方向から腕の延在方向を認識することができ、長辺の向きから腕の向きを判定することが出来る。なお、ステップS32の処理と同様に、直前の数フレームの画像データと比較して、腕の動きを検知させてもよい。
ジェスチャデータ記録ユニット455(図3参照)にストックされるジェスチャデータは、ユーザによって登録されてよい。また、ジェスチャデータは、ユーザによってジェスチャコマンドとして設定され、さらに必要に応じて書換えもされる。
図19は、ジェスチャデータ記録ユニット455へジェスチャデータを登録する処理の一例を示すフローチャートである。
動作の遷移が意図されないジェスチャの場合は、当該ジェスチャのサインを示したまま、ユーザ自身が当該ジェスチャとして意識する態様を逸脱しない程度に手および腕を様々に動かした様子を撮影することができる。
さらに、特徴部の位置および/または角度の値を分析する(ステップS45)。特徴部の位置としては、指先および指の根元を表す点など、対象における解剖学的特徴点を座標情報の付加により表すことができる。また、特徴部の角度としては、指の延在方向および腕の延在方向などに基づいた角度情報の付加により表すことができる。
より具体的には、図16のステップS26からS31と同じ処理が行われる。これによって、全ての指について同様の処理を行なうことで、全ての指のスケルトンを得る。これにより、指の延在方向、具体的には指の関節を中心とした指の角度を認識することができる。また、指先および指の根元等を示す特徴点の位置を、座標情報を付加することにより認識することができる。さらに、手の形態を認識することができる。たとえば、それぞれの指の形態(具体的には、親指、人差し指、中指、薬指、小指のいずれの指が曲げられ、いずれの指が伸びているか等)を認識することができる。
さらに、腕認識によって、腕の延在方向、具体的には肘の関節を中心とした腕の角度を判定することができる。
上述のほか、指先等を示す特徴点の座標の軌跡を含む範囲を求めることによって、可動範囲を導出することができる。
図20は、ジェスチャデータ記録ユニット455において、ジェスチャデータが、当該ジェスチャデータをコマンドとすべきアプリケーションの操作と関連付けられて記録される関連付け処理の一例を示すフローチャートである。
また、たとえば、アプリケーション操作コマンドを呼び出した後に、ジェスチャデータを直接記録させ、関連付ける態様としてもよい。
図21は、ジェスチャデータ記録ユニット455において、ジェスチャコマンドが書換えられる処理の一例を示すフローチャートである。
上述のように記録されたジェスチャデータ記録ユニット455内のジェスチャデータを利用してジェスチャの識別を行なう方法は、図4のステップS1からステップS4で説明した通りである。より具体的には、上述のジェスチャデータ登録時と同様に、ステップS2において、対象の外形イメージデータを複数フレーム取得し、それぞれ、ステップS3において、外形の特徴部およびその可動範囲の情報を取得する。さらに、ステップS4において、ジェスチャデータ記録ユニット455に記録されたジェスチャデータの外形の特徴部およびその可動範囲と、識別すべきジェスチャの外形の特徴部およびその可動範囲とを比較する。双方のデータの一致性を判断することによって、識別すべきジェスチャが、ジェスチャデータ記録ユニット455に記録されたジェスチャデータのうちどれに該当するかを判断する。
次に、図22は、眼鏡表示装置100の半透過ディスプレイ220の表示の一例を示す模式図である。
次に、眼鏡表示装置100の半透過ディスプレイ220に表示される表示の一例について説明を行なう。図23(a)は、半透過ディスプレイ220の視野の一例、図23(b)は、半透明ディスプレイ220の表示の一例を説明する図である。
図23に示すように、縦方向に表示703、702、701、704、705の表示が設けられており、表示701を中央として、左右に表示706,707が設けられる。なお、当然のことながら、当該表示701,~,707は、ユーザによって自由に削除または変更することができ、さらに他の表示を追加することもできる。
なお、本実施の形態においては、表示701,~,707はシームレスに連続した画像であるが、切換えされるべき表示は、それぞれが独立した非連続の像であってもよい。
一方、天空情報の表示703および地図情報の表示705はパノラマ表示であってよく、この場合、左右方向の動きに伴ってそれら表示703,705をスクロールさせてよい。
続いて、指、掌、手、腕が操作領域410cに存在する場合と、ジェスチャ領域410gに存在する場合との違いをユーザが認識し易いように、所定のイベントを発生させる。以下、所定のイベントについて説明を行なう。図24は、所定のイベント発生の一例を示す模式図であり、図25は、図24のイベント発生の他の例を示す模式図であり、図26は、他のイベント発生の一例を示す模式図である。
これにより、ユーザは、ジェスチャ領域410gに手が存在することを容易に認識できる。
以上の指、掌、腕認識およびイベント発生を伴う眼鏡表示装置100の使用態様について説明する。
例えば、広告221には、店舗の、商品、サービス等の情報が表示されている。ユーザがその広告221をタッチした場合、当該店舗に関するさらに詳しい情報を追加表示させてもよい。たとえば、飲食店の場合には、当該飲食店の代表メニュ、ユーザからの評価、価格帯等を表示させてもよい。
なお、広告221は、店舗をカメラユニット303で撮影された像そのものであってもよいし、カメラユニット303による当該店舗の撮像データに基づいて店舗認識を自動で開始し、その結果、店舗認識アプリ画面に表示された認識結果情報であってもよい。
また、図28に示すように、半透過ディスプレイ220に一の企業(○○社)のロゴマークが表示されている際に、画面中のロゴマークにタッチ等行なうことで、競合又は非競合の他の企業(△△社)に関連する情報を表示させることができる。この場合、例えばパロディモードとして、当該他の企業のロゴを表示させてもよい。
また、ユーザがジェスチャ領域410g内で所定の手のポーズを作ることにより、予め設定された動作が実施される。図29から図36は、ジェスチャ認識の例を示す模式図である。
続いて、追従表示システム800について説明を行う。図37は、追従表示システム800の一例におけるアイコンのツリー表示を示す模式図である。
図37に示すようにメニュー810と、複数の選択要素811,812,813,821,822,823,824,831,832,833,834,835,841,842,843,844と、メニュー810および選択要素811,812,813,821,822,823,824,831,832,833,834,835,841,842,843,844を結ぶ紐付けと、保存選択要素825と、終了選択要素826とを有する。なお、当該図37は、選択要素812,813,821,823,833,834,の全てを選択した場合に表示される状態を模式的に示す図である。図示されるように、メニュー810および選択要素811,812,813,821,822,823,824,831,832,833,834,835,841,842,843,844は、円形状アイコンであり、保存選択要素825および終了選択要素826は、矩形状アイコンである。
複数の選択要素811,812,813,821,822,823,824,831,832,833,834,835,841,842,843,844と、メニュー810および選択要素811,812,813,821,822,823,824,831,832,833,834,835,841,842,843,844を結ぶ紐付けと、保存選択要素825と、終了選択要素826とは、メニュー810を操作することにより、直接的にまたは間接的に表示される。
アイコンの操作においては、後述の図42に示すように、操作のための指H5を、選択要素823で示されるアイコンに重なるよう視認される位置へ動かす。
なお、指H5のイメージは、半透過ディスプレイ220に、操作者に視認可能であるように表示されてもよいし、操作者に視認されないように非表示にされてもよい。
図40及び図41に示すように、アイコンは、奥行きのある仮想領域内に、奥行きのある立体として仮想表示されてもよい。つまり、図12および図13で説明したような三次元空間検知領域4103Dに、奥行きを有する仮想イメージ表示領域2203Dが定義され、その中にZ方向を軸心とする円柱状、または直方体状のアイコンが表示されてもよい。さらに、指H5の実空間内の位置とアイコンの仮想空間内の位置とが所定の関係を満たしていることを、アイコン選択の判断基準としてもよい。
一方、アイコン選択操作を行う場合は、図40および図41に示すように、赤外線検知ユニット410から、仮想イメージ表示領域2203Dに表示されたメニューまたは選択要素のアイコンICHYへの中心投影による立体領域(すなわちアイコン操作領域ICAR)内に指H5が存在することを条件として、メニューまたは選択要素のアイコンICHYを選択できるものとしてよい。
以下、追従表示システム800の表示の一例について図42から図44を用い、アイコンの操作のより具体的な態様について説明を行なう。
タイマー表示823aが選択要素823のアイコンの周囲を一周する時間は、当業者が適宜設定することができる。当該時間は、例えば、0.1sec以上5.0sec以下であることが好ましく、0.2sec以上1.0sec以下であることがより好ましく、0.5secであることがさらに好ましい。
図45から図48は、メニュ画面V1の一例を示す図である。例えば、図45に示すように、手H1によるジェスチャが検知され、それを契機としてメニュ画面V1が表示され、指H5により、メニュ画面V1の選択要素の1つであるカメラアプリ起動項目V9が選択される。
