Description
図8A及び図8Bは、光源Sの光を2方向に分けて、相互に離れた2つの発光部Hを光らせるための導光管320を示す図である。
以上説明したように、入力デバイス100では、導光管20・120の入射面から発光部Hの外面h2に至る光路にある、光の媒質間の境界面に、発光部Hの外面h2から出る光の角度範囲を広げる湾曲面が形成されている。具体的には、導光管20・120(図4、図5、及び図6参照)においては、出射面22・122に凹面22a・122aが形成され、外装部材30(図7A及び図7B参照)では、発光部Hの内面h1に、光の角度範囲を広げる湾曲面が形成されている。この入力デバイス100によれば、発光部Hの外面h2から出る光の角度範囲が広がるので、カメラを通して発光部の光を検出することが容易となり、入力デバイス100の位置及び姿勢の算出精度を向上できる。
