Uwagi na temat ontologii wirtualnej rzeczywistości

The article is an attempt at collecting some views on ontology of virtual reality (VR). Two types of definitions of virtual reality are discussed and compared: technological (concentrated on technical features of VR) and psychological (concentrated on people’s experiences with VR). In the paper features of virtual reality such as: interaction, artificiality, simulation, full body immersion, networked communications, telepresence and immersion are presented as forming differentia specifica of virtual reality. The main studied issues are ontological problems connected with virtual reality especially ontological status of virtual objects. The main views on this subject are presented: 1) virtual objects are simulations of real objects, 2) some virtual object are as real as their equivalents in the reality (conception of Philip Brey based on Searle's social ontology), 3) virtual worlds as constructions of human mind. Virtual reality shades new light on some classical philosophical problems. In the paper two of them are discussed: 1) distinction between reality and appearances and 2) relations of the real world to a virtual one.
