US 2023/0418382 A1 · APPARATUS AND METHOD FOR RENDERING DYNAMIC HAPTIC RESPONSE OF FLEXIBLE OBJECT

Abstract

An apparatus and method for implementing dynamic tactile feedback of a flexible object are disclosed. The apparatus enables recognition of a continuous change in stiffness of an object due to a dynamic response of the flexible object. The method enables recognition of such changes through control of the device. The method enables a user to continuously control the stiffness of a device used as a tool for haptic feedback. This further enables various virtual world sensations associated with virtual reality or augmented reality content to be expressed in direct relation to the length, shape, material, etc. of virtual objects, and also enables various virtual world sensations to be realized through such devices.

Dependent claims

An apparatus for implementing dynamic haptic response of a flexible object (hereinafter referred to as a “virtual flexible object implementation apparatus”) comprising:

a quaternion joint that fulfills the role of a joint, capable of being bent in any direction of 360 degrees according to an applied force;
four (4) tendons, each rotating in the form of a loop, which are strings, each causing expansion or contraction depending on a particular direction in which said quaternion joint is bent;
a spool, which rotates to support the loop formed by the string of each of said tendons at one end;
a pulley supporting and rotating the loop formed by the string of each of said tendons at an opposite end of said spool;
and,
a control device for controlling the rotation of said spool of each of said tendons.

A method, by a device on which a virtual reality (VR) or an augmented reality (AR) content is operated (hereinafter referred to as a “VR/AR device”), for implementing deformation of a virtual flexible object on a screen of the VR/AR content through an operation of a VR/AR content application,

(a) receiving, from a virtual flexible object implementation apparatus, front position information of said virtual flexible object implementation apparatus measured by a front tracker, and rear position information of said virtual flexible object implementation apparatus measured by a rear tracker;
(b) calculating, from said front position information and said rear position information, for any point on said virtual flexible object in an unfolded state on the screen, a position information moved by a bending of said virtual flexible object implementation apparatus;
and
(c) rendering said virtual flexible object on the screen according to said calculated position information.
