Abstract: A virtual world processing apparatus and method. An angle value is obtained by measuring an angle of a body part of a user of a real world using sensor capability, which is information on capability of a bending sensor, and is transmitted to a virtual world, thereby achieving interaction between the real world and the virtual world. In addition, based on the sensor capability and the angle value denoting the angle of the body part, control information is generated to control a part of an avatar of the virtual world, corresponding to the body part, and then transmitted to the virtual world. Accordingly, interaction between the real world and the virtual world is achieved.

Further, the method includes finding “soft” and “hard” characters on all objects and defining the characters on all objects.

Abstract: The coordinates for laying out visual items in two-, three-, or n-dimensional space along an embedded one-manifold or path are calculated and coordinates are generated for placement of the items in a container. A one-manifold may be continuous, discontinuous, be contained entirely within a container or extent beyond a container. The one-manifold may be defined by a set of parameters defining a function, formula or set of points. The container may be a two-dimensional, three-dimensional, or n-dimensional container. Such a mechanism may be employed by a graphics application and may determine the location or positioning of an object or item. The object or item may be one of a set of objects or items. In response to receiving a set of parameters defining a one-manifold, the one-manifold may be embedded within a container.

Abstract: The present invention relates to a process and a device for the collision detection of objects by traversal of hierarcichal binary bounding BoxTrees, in which each bounding box pair of a hierarchically lower level is derived from a bounding box from the immediately above level by means of cutting off two sub-volumes by means of two parallel cut-planes. For the collision detection of a first and a second object, for each second bounding box of the bounding BoxTree of the second object to be checked for overlapping with a first bounding box of the bounding BoxTree of the first object, an auxiliary bounding box is computed which is axis-aligned in the object coordinate system of the first object and encloses the second bounding box with minimal volume, and with which the overlap check is conducted instead of with the second bounding box, and the computation results from the level immediately above are utilized for computation of auxiliary bounding boxes of lower levels.

Abstract: An apparatus and a method for processing information, and a program and a program storing medium are disclosed in which a user can surely recognize the change of images when they are operated. Upon detection of an operation, a processing manager applies, every predetermined period, a transition function to an elapsed time from the detection of the operation to compute a ratio of the movement of an image to a distance from the current position of the displayed image to a destination specified by the operation. On the basis of the obtained ratio of the movement of the image, the processing manger specifies a display position of the image toward the destination. A content processing routine controls the display so that the image is displayed at the specified position every predetermined period.

Abstract: A collision of a moving object with another object in a 3D virtual world is efficiently determined in real time so that the technique is usable over a network. An object in the 3D virtual world is projected onto a 2D plane. The projection of the object is bounded by a two-sided edge cycle that is formed from a sequence of line segments having endpoints that are consecutively joined at an ordered series of vertices. One side, which is formed by a counterclockwise ordering of the line segments and their respective vertices, is characterized as "front facing." The other side is characterized as "back facing." Additionally, the front and back facing characterization of a side of the edge cycle is determined by the disposition of the moving object, i.e., the closest side of the edge cycle to the moving object is its back facing side. A path line segment is developed for the projection of a path of a moving object onto the 2D plane, and a path line equation is determined for the path line segment.
