Patent ID: 8402393

Claim:
A virtual object manipulating apparatus for manipulating a virtual object, the apparatus comprising: a database storing a shape of at least one reference object; a corresponding point searching unit to search for a plurality of corresponding points by comparing a shape of a virtual object selected by a user with a shape of the virtual object manipulating apparatus, wherein the corresponding point searching unit detects a plurality of vertexes being on a surface of the shape of the virtual object; a grab type recognizing unit to sense a grab signal from the user and to recognize a grab type of the virtual object manipulating apparatus; and a virtual grab type determining unit to determine a virtual grab type of the selected virtual object based on the plurality of corresponding points and the grab type of the virtual object manipulating apparatus wherein the determination of the virtual grab type determining unit is performed by: identifying a reference grab type corresponding to the grab type of the virtual object manipulating apparatus as the virtual grab type of the selected virtual object, the corresponding reference grab type is associated with at least one reference object corresponds to the shape of the virtual object wherein both the corresponding reference grab type and the at least one reference object is stored in the database.
