US 7,460,125 B2 · Apparatus and method for immediately creating and controlling virtual reality interactive human body model for user-centric interface

Abstract

Provided is an apparatus and method for immediately creating and controlling a virtual reality interactive human body model for a user-centric interface. The apparatus and method can transform a whole body three-dimensional (3D) default model into a model close to the body of a user by collecting data from the user's hands, generates a user coincident 3D model by selecting a skin texture map and applying it to the transformed model, and controlling the user coincident 3D model in a deformable polygon mesh structure to naturally visualize the motion of the user coincident 3D model. The apparatus and method can make users participate in a virtual reality system conveniently and work naturally in the same manner as reality, i.e., interaction. The apparatus and method provides ordinary users with an easy access to virtual reality systems and overcomes the shortcomings of existing virtual reality systems which simply provide visual effects.

Dependent claims

An apparatus for immediately creating and controlling a virtual reality interactive human body model for a user-centric interface, comprising:

a whole body three-dimensional (3D) default model creation unit for creating a whole body 3D default model based on gender and age of a user and a body measurements database;
a user hand image acquisition unit for acquiring hand measurement data and skin color data from a hand image of the user which are acquired by an image acquisition device;
a user coincident body model transformation unit for predicting measurements of body parts from the hand measurement data and scaling the whole body 3D default model to thereby produce a user coincident 3D body model;
a skin texture map selection and application unit for applying a skin texture map to the user coincident 3D body model based on the skin color data of the user's hand;
and
a real-time motion synchronization unit for linking and synchronizing user tracking data with a hardware interface for real-time interaction.
