Consolidated manipulation of virtual and real objects
Yoshifumi Kitamura, Fumio Kishino · 1997
We propose a manipulation environment with virtual and real objects by providing a consolidated manipulation manner for both objects.This approach assists the user and improves the task performance of object manipulation (e.g., speed and accuracy).A limited kinds of physical laws are selected and simulated for virtual objects; at the same time, limitations on the physical laws for real objects are introduced.Accordingly, we reached a compromise between the physical laws that operate on both virtual and real objects.The proposed environment enables a user to manipulate virtual and real objects in the same manner by expecting the same response according to the same physical laws.In the environment, real objects are treated as "substantial" as they are, without using insubstantial images taken by cameras or graphical images generated from geometric shape representations of objects.It is possible to bring a real object into a virtual world on demand, according to the user's irregular and sudden requirements, without using troublesome procedures to reconstruct the object shapes.The configuration of an object manipulation environment using a "magnetic metaphor" is shown as an example.This environment is suitable .forobject manipulation in a combined virtual/real world.
