To Pascual-Espada et al (2011) the concepts of entity ((
virtual object) such as cinema tickets), resource, device, and service are considered as the main concepts.
Leushkin believes that "modern understanding of a
virtual object identifies such a characteristic of it as incompleteness of existence.
Before the first cycle of trial, the children received training on basic SL operations which included how to move their avatars in SL, how to interact with the
virtual objects by clicking, and how to listen to the questions posed by the system and to answer them by taking the correct actions.
There are 12 researches reviewed; most of the researches (50%) used card with marker as interaction medium to interact with
virtual object. 18% used cube to manipulate the
virtual object.
2) is used to implement new modern algorithms, to control technological process, to train skills of programming control systems on industrial equipment with next training on
virtual object. This approach provides an unlimited number of virtual control objects in MATLAB/Simulink with visualization of the process for education and organization laboratory or practical classes.
Tachibana, "
Virtual object manipulation on a table-top AR environment," in Ieee, 2000.
In software, there is a software support environment; there is a set of tools that can generate
virtual objects and
virtual objects; it is capable of receiving all kinds of functions of high performance sensor information, it can generate and display the function of the stereoscopic graphics.
This provides a real-time interaction with the real and
virtual objects. AR is related to a mediated reality, in which a view of reality is modified using a computer system.
A temperature sensor is an object on the other hand shoppers and guard are different kind of objects and all of the objects can be represented as
virtual object. Here, they created
virtual object which is related to each other by semantic ontology.
"Stealing" a
virtual object, in this technical view, amounts to causing a change in the database on the game server (namely, a change in the records of who owns which objects).
