Abstract: A space registration system includes a display apparatus, an image sensor, a processor, and a plane mirror. The display apparatus has an inherent display coordinate system which defines a coordinate of the virtual space. The image sensor has an inherent sensor coordinate system which defines a coordinate of the real space. The processor analogizes a transformation equation of the sensor coordinate system and the display coordinate system by means of symmetry of an incidence angle and a reflection angle of light with respect to the mirror surface, compares a coordinate of the reflection image with respect to the display coordinate system with a known coordinate of the reflection image with respect to the sensor coordinate system, and adjusts the transformation equation of the sensor coordinate system and the display coordinate system.

Abstract: A method and apparatus for motion capture interface using multiple fingers are disclosed. The method includes measuring a position of an end of a middle finger of an actual hand in a state in which the actual hand is spread, deriving a starting reference position of the middle finger of the actual hand, and calculating a length of the middle finger of the actual hand. The method further includes recognizing a relationship between starting reference positions of a thumb, an index finger, a middle finger, and a wrist based on using a virtual hand reference model that models a virtual hand to be controlled.
