USER INTERFACE DEVICE FOR PROVIDING FORCE FEEDBACK ACCORDING TO INTERACTION WITH VIRTUAL OBJECT OR USER AT REMOTE PLACE

摘要

Provided is a hand-held type user interface device for providing force feedback to a user according to an interaction with a virtual object or a user at a remote place, which remarkably increases the sense of reality in the interaction with the virtual object without limiting an action of the user by sensing the three-dimensional (3D) position and direction of the device and diversifying a force feedback provided to the user according to an action of the user holding the device.

主权项

1. A user interface device for providing force feedback to a user according to interaction with a virtual object or a user at a remote place, the user interface device comprising:
a body formed to have a length direction and having a fastening means for fastening the user's hand; a first infrared (IR) generator located in a first stage of the body and configured to generate interaction-purpose IR rays for pointing at an arbitrary point of the virtual object or interacting with the user at the remote place; a sensor configured to sense the length direction of the body in three-dimensional (3D) space; a power generator configured to acquire a power generation signal corresponding to a direction of force with reference to the length direction of the body and generate power when information on the direction of the force exerted by the user on the virtual object or the user at the remote place is acquired and information on the length direction of the body is acquired through the sensor while the interaction-purpose IR rays point at the arbitrary point of the virtual object or a predetermined region of an image corresponding to the user at the remote place; and a force feedback provider configured to provide force feedback to the user according to the power generated by the power generator.
