Abstract: Disclosed are a method and an apparatus for predicting human motion in a virtual environment. The apparatus includes a motion tracking module configured to estimate a human pose of a current time step based on at least one piece of sensor data and a pre-learned motion model, and a motion model module configured to predict a set of probable human poses in the next time step based on the motion model, the estimated human pose of the current time step, and virtual environment context information of the next time step. A sense of immersion of the virtual environment may be maximized.

Abstract: Disclosed herein are a method and apparatus for authenticating a user based on a fingertip gesture. The authentication apparatus may display a pattern generated based on geometric information about a hand geometry or size of a user, and may recognize a fingertip gesture via interaction with the user with respect to the pattern. The authentication apparatus may authenticate a user using the recognized fingertip gesture. The pattern may include a gesture inducement/relation pattern and a fake pattern. Information about the fingertip gesture may include fingertip touch locations of the fingertip gesture, a touch order of the fingertip touch locations, and a moving direction of the fingertip touch locations.
