を実行させる、命令を含むプログラムを記録していることを特徴とする。
以下、本発明の実施の形態1における、触力覚提示装置、情報端末、触力覚提示方法、及びプログラムについて、図1~図3を参照しながら説明する。
最初に、図1及び図2を用いて、本実施の形態1における触力覚提示装置及び情報端末の構成を説明する。図1は、本発明の実施の形態1における情報端末の外観を示す斜視図である。図2は、本発明の実施の形態1における情報端末の各構成部品を示す分解斜視図である。
次に、本発明の実施の形態1における情報端末100及び触力覚提示装置10の動作について図5を用いて説明する。図5は、本発明の実施の形態1における情報端末100の動作を示すフロー図である。なお、以下の説明においては、適宜図1~図4を参酌する。また、本実施の形態1では、触力覚提示装置10を動作させることによって、触力覚提示方法が実施される。よって、本実施の形態における触力覚提示方法の説明は、以下の触力覚提示装置10の動作説明に代える。
まず、図6を用いて、ステップS101及びS102について具体的に説明する。図6は、本発明の実施の形態1において用いられるコンテンツの一例を示す図である。図6の例では、コンテンツはエアホッケーゲームであり、ユーザ70は、指先のタッチによって、仮想空間内に存在している仮想マレット21を操作して、仮想パック22を打撃する。
次に、図7及び図8を用いて、ステップS105で行われる触力覚の提示制御処理について詳細に説明する。図7は、図5に示したステップS105を具体的に示すフロー図である。図8は、アクチュエータの引張力の算出処理を説明する図である。
(a)引張力τ1~τ4の合力が、オブジェクト(仮想マレット21:図6参照)に仮想空間内で発生した力、即ち、ステップS102で計算した提示力Fと一致すること。
(b)引張力τ1~τ4によって触力覚提示部材11に生じるモーメントMが、仮想空間内でオブジェクトに発生したモーメントに一致すること。
(c)引張力引張力τ1~τ4それぞれが、ワイヤ12aが弛まない最小の引張力τmin以上であり、且つ、最小の引張力τminは0(ゼロ)より大きいこと。
(d)引張力τ1~τ4の合計値が、条件(a)~(c)が満たされる範囲内で最小値となること。
本実施の形態1におけるプログラムは、コンピュータに、図5に示すステップS103~S106を実行させるプログラムであれば良い。このプログラムをコンピュータにインストールし、実行することによって、本実施の形態1における触力覚提示装置10と触力覚提示方法とを実現することができる。この場合、コンピュータのCPU(Central Processing Unit)は、制御部14として機能し、処理を行なう。
以上のように、本実施の形態1によれば、触力覚提示部材11の移動による触力覚と、伝達速度の速い振動とを組み合わせて、ユーザに提示できるので、ユーザが触力覚の提示の時間遅れを感じ難くすることができる。また、この結果、以下の効果を得ることが可能になる。
次に本発明の実施の形態2における、触力覚提示装置、情報端末、触力覚提示方法、及びプログラムについて、図10及び図11を参照しながら説明する。図10は、本発明の実施の形態2における情報端末の各構成部品を示す分解斜視図である。図11(a)及び図11(b)は、図10に示すアクチュエータの具体的な構成を示す図であり、図11(a)は平面図、図11(b)は側面図である。
続いて、上述した実施の形態1及び2の各種変形例について以下に説明する。まず、実施の形態1及び実施の形態2においては、表示パネル20は、触力覚提示部材11と一緒に移動しないが、表示パネル20も、触力覚提示部材11と一緒に移動しても良い。更に、図2に示した透明なパネルの代わりに、表示パネル20自体を、触力覚提示部材11として用いても良い。
続いて、上述した実施の形態1及び実施の形態2の各種適用例について以下に説明する。
まず、アクチュエータによる触力覚の提示が行なわれる迄に、疑似的に時間遅れを発生させ、その際に、振動の有無によって、ユーザが時間遅れをどのように感じるかを検証した。
次に、振動の継続時間の長さと、ユーザにおける時間遅れの感じ方との関係について検証した。
