Abstract
Description
図1は、一実施形態に係る操作装置100の側面図である。図2は、一実施形態に係る操作装置100の外観斜視図である。図1および図2に示す操作装置100は、各種電子機器(例えば、ゲームコントローラ等)に用いられ、ユーザの押込等による移動操作が可能である。図1および図2に示すように、操作装置100は、上下方向(Z軸方向)に延在する操作軸101(「操作部」の一例)を有する。操作軸101には、操作ノブ101Bが取り付けられている。図1および図2に示す例では、操作ノブ101Bは操作軸101の上端部に取り付けられている。操作装置100は、操作ノブ101Bの下方への押込操作(「移動操作」の一例)により、操作軸101を下方へ移動させることができる。操作軸101の下方への移動量は、センサ103によって検知され、センサ103から、制御装置10に対して出力される。
一実施形態に係る操作装置100は、操作ノブ101Bの押込操作がなされると、操作軸101が下方へ移動する。この際、操作軸101の移動量は、センサ103によって検知される。また、この際、操作装置100は、力覚発生器102によって、操作軸101に対して上下方向(Z軸方向)への駆動力を加えることが可能となっている。そして、操作装置100は、操作軸101の先端部101Aが調整部104の当接面104Aに当接することで、操作軸101の下方への移動量が制限されるようになっている。
図3は、一実施形態に係る操作装置100が触覚呈示制御に使用する負荷特性の一例を示すグラフである。図3に示すグラフは、操作装置100が備える制御装置10によって、操作ノブ101Bによる押込操作の負荷を制御するために用いられる負荷特性を表すものである。図3に示すグラフにおいて、縦軸は、押込操作の負荷を表し、横軸は、押込操作の押し込み量(すなわち、操作軸101の下方への移動量)を示す。また、図3に示すグラフにおいて、P1は、「第1の押し込み位置」(押し込み量448)を示しており、P2は、「第2の押し込み位置」(押し込み量880)を示しており、P3は、「第3の押し込み位置」(押し込み量1024)を示している。
図4は、一実施形態に係る操作装置100が備える制御装置10の機能構成の一例を示す図である。図4に示すように、制御装置10は、計測部11、取得部12、変換部13、変換情報記憶部14、負荷特性記憶部15、負荷制御部16、生成部17、および検出値取得制御部18を備える。
図5は、一実施形態に係る操作装置100が備える制御装置10による処理の手順の一例を示すフローチャートである。
図6は、一実施形態に係る操作装置100が備える調整部104の構成の一例を示す図である。図6に示すように、調整部104は、螺旋階段状の当接面104Aを有する。これにより、調整部104は、当該調整部104が回転することで、当接面104Aにおける、操作軸101の先端部101Aが当接する当接位置を、段階的に変更することができ、よって、操作軸101の移動限界位置を段階的に変更することができる。特に、図6に示す例では、当接面104Aは、10段の螺旋階段状を有する。このため、一実施形態に係る操作装置100は、調整部104を36°毎に回転させることで、当接面104Aにおける、操作軸101の先端部101Aが当接する段を、順次変更することができる。
図7は、一実施形態に係る操作装置100が備えるセンサ103による操作軸101の位置の検出方法を説明するための図である。
図8は、一実施形態に係る操作装置100において用いられる、移動限界位置毎の位置情報および検出値の一例を示す図である。
図9は、一実施形態に係る操作装置100が備える制御装置10による変換情報の生成例を示す図である。図9に示すグラフは、制御装置10の生成部17によって生成された近似式を表すものであり、縦軸は操作軸101のストローク位置を示し、横軸はセンサ103の検出値を示す。
以上説明したように、一実施形態に係る操作装置100は、移動操作可能な操作軸101と、操作軸101の位置に応じた検出値を出力するセンサ103と、センサ103から出力された検出値を取得する取得部12と、変換情報に基づいて、取得部12によって取得された検出値を操作軸101の位置に変換する変換部13と、操作軸101の移動限界位置を調整可能な調整部104と、調整部104によって調整可能な複数の移動限界位置の各々について、操作軸101が当該移動限界位置に到達したときの検出値をセンサ103から取得し、取得された複数の検出値と、複数の移動限界位置の各々の実際の位置を示す位置情報とに基づいて、変換情報を生成する生成部17とを備える。
