Depending on embodiments, the user 110 of the real world may be humans, animals, plants, and inanimate objects (e.g., objects), and also may be a surrounding environment of the user.
Referring to
The CI may be a command, based on values, inputted using the real world device, and information associated with the command. The CI may include sensory input device capabilities (SIDC), user sensory input preferences (USIP), and sensory input device commands (SIDCmd).
Adaptation real world to virtual world (hereinafter, referred to as ‘adaptation RV’) may be implemented by a real world to virtual world engine (hereinafter, referred to as ‘RV engine’). The adaptation RV may convert information of the real world into information adaptable in the virtual world. In this instance, the information of the real world may be inputted via the real world device using the CI regarding the behavior, the state, the intention, the type, and the like, of the user of the real world included in the sensor signals. The above-described adaptation process may have an influence on virtual world information (VWI).
The VWI may be information regarding the virtual world. For example, the VWI may be information regarding elements constituting the virtual world, such as, a virtual object or an avatar. The VWI may be changed in the RV engine in response to commands, for example, virtual world effect metadata (VWEM), virtual world preferences (VWP), and virtual world capabilities (VWC).
Table 1 shows configurations described in
Referring to
Sensor signals including CI 302 inputted through the sensor 301 may be transmitted to the virtual world processing apparatus. As examples, the CI 302 may be associated with an action of spreading the arms of the user 310, a state in which the user 310 stands in place, a position of hands and feet of the user 310, an angle between the spread arms, and the like.

Depending on embodiments, the VWI 303 may include virtual world object information 304, and avatar information 305.
The virtual world object information 304 may be information regarding the object of the virtual world. Depending on embodiments, the virtual world object information 304 may include an object identifier (ID) for identifying an identity of the object of the virtual world, and include object control/scale, namely, information used to control a state, a size, and the like of the object of the virtual world.
The RV engine 320 may convert the VWI 303 by applying, to the VWI 303, information regarding the action of spreading the arms, the state in which the user 310 stands in place, the position of the hands and feet, the angle between the spread arms, and the like, based on the CI 302.
The RV engine 320 may transfer information 306 regarding the converted VWI 303 to the virtual world. Depending on embodiments, the information 306 may include position information regarding arms and legs of an avatar of the virtual world that are expressed as ΘXvirtual,ΘYvirtual, and ΘZvirtual namely, values of angles with the x-axis, the y-axis, and the z-axis, and that are expressed as Xvirtual, Yvirtual and Zvirtual namely, values of the x-axis, the y-axis, and the z-axis. Additionally, the information 306 may include information regarding the size of the object of the virtual world that is expressed as a scale (w, d, h)virtual indicating a width value, a height value, and a depth value of the object.
Depending on embodiments, an avatar in a virtual world 330 to which the information 306 is not transferred may be in a state of holding the object. Additionally, an avatar in a virtual world 340 to which the information 306 is transferred may spread arms of the avatar to scale up the object by applying, to the virtual world 340, the action of spreading the arms, the state in which the user 310 stands in place, the position of the hands and feet, the angle between the spread arms, and the like.
Specifically, when the user 310 of the real world takes a motion of gripping and scaling up the object, the CI 302 regarding the action of spreading the arms, the state in which the user 310 stands in place, the position of the hands and feet, the angle between the spread arms, and the like, may be generated using the sensor 301. Additionally, the RV engine 320 may convert the CI 302 associated with the user 310 of the real world, that is, data measured in the real world, into information applicable to the virtual world. The converted information may be applied to a structure of information regarding the avatar and the object of the virtual world, so that a motion of gripping and spreading the object may be applied to the avatar, and that the object may be scaled up.
