Patent number: 8932183Abstract: A training system for training of part of a trainee's body includes a training machine, a control device controlling the training machine, and a display unit displaying a game screen. The training machine imposes a load on the trainee, with an MR-fluid load generating unit using MR fluid, which has viscosity varying with a magnetic field strength. The load is calculated on the basis of a target load and a relationship between the current in the MR-fluid load generating unit and the load generated by the MR-fluid load generating unit. The control device produces the game screen in correspondence with the trainee's training motion detected by a displacement detection sensor, and makes the display unit display the game screen, while controlling the load in the training machine.Type: GrantFiled: December 6, 2011Date of Patent: January 13, 2015Assignees: Hitachi, Ltd., Takei Scientific Instruments Co., Ltd., Yokohama National UniversityInventors: Hiroshi Ishii, Sizuo Takatou, Kenichi Honda, Hajime Watanabe, Kouichi Yamada, Yasuyuki Murayama, Toshihiko Shiraishi, Shin Morishita
