Abstract
Description
本実施の形態のインタラクション装置1は、以上の構成を備えており、次のように動作する。以下の例では、装置本体11が、図1に例示したように実質的に球形の頭部11aと、実質的に球形の胴体部11bとを連結した形状を有しているものとする。つまり、外殻体110は連結された頭部11a及び胴体部11bに対応した形状に形成されているものとする。また外殻体110の外側には、フェイクファー生地などを用いた外装体112が装着されているものとする。
・外装体112に手を近づける動作、
・外装体112に触れる動作、
・外装体112表面を撫でる動作、
・外装体112を介して装置本体11の外殻体110を押圧する動作、
・外装体112を介して装置本体11の外殻体110を押圧して変形させる動作、
・外装体112表面を叩く動作
・外装体112表面に触れ、あるいは押圧している状態から手を離す動作
…
などを行う。またユーザは、インタラクション装置1を、持ち上げて移動する動作を行ってもよい。
さらに本実施の形態のインタラクション装置1では、外装体110表面に外装体112が配されていることから、外装体112の材質によってはユーザが接触したり手を離したりしたときなどに帯電し、静電容量センサ12の検出結果に影響を与えることが考えられる。
情報処理装置20は、以上の推定を行った結果を用いて、ユーザがインタラクション装置1に対して行った操作の内容を、他の情報処理装置20へ送出して、当該他の情報処理装置20を利用するユーザの手などに与える刺激を制御させてもよい。
本発明の実施の形態によれば、例えば毛皮等で被覆したインタラクション装置であっても、毛皮の直下に配した外殻体の内側表面に沿って静電容量センサを配することが可能となる。そこで、毛皮に接触する程度のユーザの手の近接を検出して、毛皮への接触及びその強さや接触箇所を推定させる処理に供することが可能となる。これより、インタラクション装置の外装の自由度を向上できる。
