Abstract: The present invention relates to a kinesthetic-feedback wearable apparatus which realizes a kinesthetic-feedback in a virtual reality (VR) or augmented reality (AR), and more particularly to a kinesthetic-feedback wearable apparatus which provides a resistance, which is suitable for a situation in a virtual reality or augmented reality, to a user by using a propeller in a state in which a virtual reality or augmented reality device is mounted to the user who uses the virtual reality or augmented reality device. According to the present invention, a reactive force for a kinesthetic-feedback can be easily realized through a scheme of attaching a light propeller to a wrist, and reactive forces of various directions may be realized only with a small number of propellers by allowing the directions and the RPMs of the propellers to be separately controlled for a higher degree of freedom when two or more propellers are provided.
