Movable display apparatus, robot having movable display apparatus and display method thereof

摘要

A movable display apparatus, a robot having the movable display apparatus, and a display method thereof, and, more particularly, a display method of a robot having an apparatus to display an image according to a visual point of a user are provided. It is possible to provide a convenient extended image service, by movably mounting the apparatus to display the image according to the visual point of the user and mounting the movable display apparatus in the robot so as to accurately display the image according to the visual point of the user using the mobility and motion of the robot. In addition, it is possible to provide an image, which is viewed like a three-dimensional image, via a two-dimensional display apparatus, by changing the displayed image according to a variation in the sightline of the user.

主权项

1. A movable display apparatus comprising:
a display unit configured to display an image; a camera provided on the display unit and configured to acquire an image of a user; a head mounted device (HMD) configured to measure a head rotation direction and a pupil direction of the user; a control unit configured to recognize a sightline of the user using the image of the user acquired by the camera and the head rotation direction and the pupil direction measured by the HMD, control a posture of the display unit according to the recognized sightline of the user, and control the displaying of the image by the display unit according to the recognized sightline of the user; a camera image processing unit configured to extract a face direction of the user from the image of the user acquired by the camera, wherein the control unit is further configured to estimate the head rotation direction for recognizing the sightline of the user using the extracted face direction and the measured head rotation direction of the user; and a driving unit configured to move the display unit under the control of the control unit, wherein the display unit is configured to be movably provided on a manipulator to display the image, and the control unit is configured to compute a difference between a sightline position of the user based the recognized sightline of the user and a current position of the display unit, and generate a motion path of the manipulator.
