Force feedback input device

摘要

When a knob is turned by a predetermined turning angle ± and this angle is detected by a rotary encoder, an electromagnetic brake is activated by a controller and the rotation of the knob is locked. Then, while the knob is locked by the electromagnetic brake, the controller determines whether an operating force was applied to the knob in direction A in which the turning angle of the knob is increased. If the controller determines that the operating force was not applied to the knob in direction A (if the operating force was applied in direction B), the locking of the knob is released.
