Abstract
Disclosed is an apparatus for outputting a virtual keyboard, the apparatus including: a virtual keyboard image output unit determining coordinates of a virtual keyboard image by using hand information of a user and outputting the virtual keyboard image; a contact recognition unit determining a contact state by using collision information between a virtual physical collider associated with an end point of a user's finger and a virtual physical collider associated with each virtual key of the virtual keyboard image; a keyboard input unit providing multiple input values for a single virtual key; and a feedback output unit outputting respective feedback for the multiple input values. Accordingly, input convenience and efficiency may be provided by outputting the virtual keyboard in a three dimensional virtual space and reproducing an input method using a keyboard form that is similar to the real world.
