The exposition is conducted on an example of the cybernetic bicycle, developed by author''s collective, - hardware-software complex permitting to the cyclist to move in the virtual world (VRML - the world) and to interact from it by objects. Operational modes - ground (with binding to a relief of district) or the air traveling on autonomous or network (is necessary connection to Internet) for the virtual worlds. The structure of a base configuration is resulted: Fixed a bicycle with installed on him trackball both gauges of a turn angle of a control surface and rotation rate of a sprocket. · Universal Internet- Ethernet the controller for data transfer between a bicycle and personal computer (protocol UDP/IP, Ethernet 10Base-T). · Personal computer of a type Wintel (Windows + Intel), Windows 98 or is higher, the browser Internet Explorer 5.0 and is higher with a module Cortona VRML Client ParallelGraphics. The examples of use in education, culture, art, architecture, tourism, teleactivity, presentation and entertaining systems etc., developed for want of fulfillment of the author''s projects under the programs and grants of Administration of St.-Petersburg (preparation and celebration of 300-year''s anniversary of city), Ministry of Education, RFBR etc. are resulted.
