図6~8は、実施例2に係る軌跡生成部による処理の流れを示す図である。図6に示すように、ゴルフスイング時の腰の動作軌跡生成に関わるスイング測定の開始を待機する(ステップS1)。そして、例えば、「スイング測定」を選択する入力があると、軌跡生成部160は、測定を開始し(ステップS1肯定)、腰姿勢マトリクス(R)、初期条件(腰の位置ベクトル:p=0,腰の速度ベクトル:v=0)を設定する(ステップS2)。
上述してきたように、実施例2によれば、携帯電話100は、ゴルフスイングのスイング開始からインパクトまで間と、インパクトからスイング終了までの間とに分けて、ゴルフスイング中に発生しているオフセット加速度をそれぞれ導出する。携帯電話100は、実測された加速度センサ値からオフセット加速度を差し引いた後、境界条件にしたがった積分を実行することで、オフセット加速度の分を補正した位置姿勢をインパクトの前後に分けて導出する。そして、携帯電話100は、インパクトの前後に分けて導出された位置姿勢から、ゴルフスイング中の腰の動作軌跡を生成して表示する。このようなことから、実施例2によれば、インパクト動作が体の所定部位の軌跡導出に与える影響を考慮することができ、ゴルフスイング中の腰の動作軌跡をより正確に再現できる。
例えば、図2に示した携帯電話100の各構成要素は機能概念的なものであり、必ずしも物理的に図示の如く構成されていることを要しない。すなわち、携帯電話100の分散・統合の具体的形態は図示のものに限られず、例えば、軌跡生成部160を位置姿勢導出部および動作軌跡生成部に機能的あるいは物理的に分散する。このように、携帯電話100の全部または一部を、各種の負荷や使用状況などに応じて、任意の単位で機能的または物理的に分散・統合して構成することができる。
また、上記の実施例で説明した携帯電話100の各種の処理(図6~8参照)は、あらかじめ用意されたプログラムをパーソナルコンピュータやワークステーションなどのコンピュータシステムで実行することによって実現することもできる。
