SYSTEM AND METHOD FOR HUMAN COMPUTER INTERACTION
First Claim
Patent Images
1. A system for human computer interaction (HCI), the system comprising:
- an image acquisition unit to acquire image data;
a line of sight (LOS) catch unit to detect a LOS of a user by detecting a pitch direction and a deflection direction of a head of a user based on the image data; and
an interaction determining unit to determine an interaction based on the LOS of the user detected by the LOS catch unit.

Abstract
A system and method for human computer interaction (HCI). may acquire image data, determine an interaction intended to be conducted by a user based on various gestures and poses of the user detected from the image data, and perform an operation and/or function which is displayed on a display of a display unit, in response to a result of the interaction.

11. A method for human computer interaction (HCI), the method comprising:
-
acquiring image data; detecting a gesture of a user by tracking and recognizing a gesture of a first body part of the user when the user is within a predetermined distance from an image acquisition unit to acquire the image data; and detecting the gesture of the user by tracking and recognizing a gesture of a second body part of the user when the user is located at or beyond the predetermined distance from the image acquisition unit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method for human computer interaction, the method comprising:
-
acquiring, using a camera, image data of a user positioned away from a display; determining a line of sight and a pose of a user based on the image data; calculating an intersection point at which a direction indicated by at least one body part of the user intersects with a screen of the display; detecting a gesture of the user by tracking and recognizing a gesture of the at least one body part of the user; and determining an interaction intended to be performed by the user based on the calculated intersection point, detected gesture, and the direction indicated by the at least one body part.
