Abstract
The present disclosure relates to a method and device based on a viscosity-variable haptic glove using MR fluid. A method for providing haptic feedback through a haptic glove according to an embodiment of the present disclosure may comprise: detecting an object in a virtual reality (VR) space; controlling an electromagnetic field for an actuator based on a magneto-rheological fluid (MR fluid) mounted on the haptic glove based on properties of the detected object; and providing haptic feedback to a user of the haptic glove using properties of the MR fluid that change based on the controlled electromagnetic field.

A method for providing haptic feedback through a haptic glove, the method comprising:
- detecting an object in a virtual reality (VR) space;
- controlling an electromagnetic field for an actuator based on a magneto-rheological fluid (MR fluid) mounted on the haptic glove based on properties of the detected object;
- and
- providing haptic feedback to a user of the haptic glove using properties of the MR fluid that change based on the controlled electromagnetic field,
- wherein, when the actuator is compressed or extended, the MR fluid flows through a set path within the actuator and undergoes a flow mode within internal passages of the actuator and a shear mode on outer walls of the internal passages.
An apparatus of providing haptic feedback through a haptic glove, the apparatus comprising:
- at least one processor and at least one memory,
- wherein the processor is configured to:
- detect an object in a virtual reality (VR) space;
- control an electromagnetic field for an actuator based on a magneto-rheological fluid (MR fluid) mounted on the haptic glove based on properties of the detected object;
- and
- provide haptic feedback to a user of the haptic glove using properties of the MR fluid that change based on the controlled electromagnetic field,
- wherein, when the actuator is compressed or extended, the MR fluid flows through a set path within the actuator and undergoes a flow mode within internal passages of the actuator and a shear mode on outer walls of the internal passages.
A non-transitory computer readable medium storing one or more instructions,
- wherein the one or more instructions are executed by one or more processors and control an apparatus for providing haptic feedback through a haptic glove to:
- detect an object in a virtual reality (VR) space;
- control an electromagnetic field for an actuator based on a magneto-rheological fluid (MR fluid) mounted on the haptic glove based on properties of the detected object;
- and
- provide haptic feedback to a user of the haptic glove using properties of the MR fluid that change based on the controlled electromagnetic field,
- wherein, when the actuator is compressed or extended, the MR fluid flows through a set path within the actuator and undergoes a flow mode within internal passages of the actuator and a shear mode on outer walls of the internal passages.
