PROGRAM METHOD, SYSTEM AND PRODUCT FOR INTERACTION IN VIRTUAL REALITY ENVIRONMENTS THROUGH A HAPTIC DESKTOP FORCES FEEDBACK DEVICE
ES2807674
Method, system and program product for interaction in virtual reality environments using a desktop force feedback haptic device (502). Method (100) comprises: defining (102) an action space (210) in a virtual reality environment corresponding to a workspace (510) of the haptic desktop force feedback device (502); upon detection (104) of a modification order (512) of the action space (210), modifying (106) the size of the action space (210) as a function of the modification order (512) detected; determining (107) the location of the modified action space (210') to keep the position of the virtual avatar (206) unaltered; and mapping (108) the workspace (510) of the haptic desktop force feedback device (502) to the modified action space (210'); upon detection (110) of a repositioning order (514) of the action space (210), moving (112) the action space (210) to a new location in the virtual reality environment as a function of the repositioning order (514) detected.

Advantages / Applications The method described in the patent is based on the assumption that the user wears an HMD that allows immersive visualization of the virtual reality experience. The new interaction model is based on offering the possibility of accessing the entire virtual workspace from the physical workspace of the haptic device, which is transferred to the virtual space in the form of what we call the action area. The technique establishes a correspondence that allows haptic interaction with the elements that are within this action area, defining also the way to move this area throughout the virtual scene. The main advantage of this method lies in the fact that the sense of touch can be included in a 360º virtual scene. The possible applications are all those in which the sense of touch is a fundamental contribution, such as in the case of surgery, the assembly of parts or teleoperation in environments that are not safe for humans (nuclear power plants, outer space...). Main differential points that provide the patent The clear differentiating fact is that there is no other patent to date that defines a haptic interaction technique in immersive virtual reality environments for force feedback haptic devices with limited workspace.
