摘要: A magneto-rheological fluid includes: a magnetic particle mixture; and a dispersion medium in which the magnetic particle mixture is dispersed. The magnetic particle mixture includes first magnetic particles and second magnetic particles. The first magnetic particles have an average particle size greater than or equal to 1 μm and less than or equal to 50 μm. The second magnetic particles have an average particle size greater than or equal to 20 nm and less than or equal to 200 nm, and have surfaces provided with a surface modified layer. A proportion of the second magnetic particles in the magnetic particle mixture is greater than or equal to 2 wt % and less than or equal to 10 wt %.

摘要: Inside a stick base, a variable resistor and a magnet brake are attached to a turnable first bridge. An A/D converter adapted to convert an analog value corresponding to a turning angle, which is obtained from the variable resistor, to a digital value, and a controller adapted to drive the magnet brake when a signal from the A/D converter is given and coincides with a predetermined value are provided. On the basis of data retained in a memory, current is applied to a coil of the magnet brake. Doing so makes it possible to electrically change operational feeling when turning a stick.

摘要: A haptic feedback device for virtual objects includes a head-mounted display unit, an HMD control unit, a haptic feedback unit, and a haptic information DB for storing haptic information in association with each type of virtual object. The HMD control unit includes a display controller that causes a virtual object and a user focus to appear on a display, and a haptic information transmitter that reads, when the user focus is placed over a selectable virtual object, haptic information associated with the type of the selected virtual object from the haptic information DB, and transmits the haptic information to the haptic feedback unit. The haptic feedback unit includes a movable portion movable with a user operation, a movement resistance generator that applies movement resistance to the movable portion, and a power feed controller (movement resistance controller).
