Method for tracking and displaying user's spatial position and orientation, a method for representing virtual reality for a user, and systems of embodiment of such methods

摘要

The invention relates to methods and systems for determination of position and orientation of users in a space and display of virtual space, and can be used in interactive computer games, health- strengthening teaching devices, or trainings of the athletic and military purposes. The invention provides an improved accuracy and speed of tracking of the user's spatial position and orientation, provides convenience for and naturalness of his/her movements and representation of virtual space in conformity with user's movements in the real space. Sensors 4 for tracking angular position of segments 2 of the user's locomotor system are attached at places of articulations 3 of segments 2 and at certain segments 2 proper. At least at one of segments 2 arranged are main means 5 for determination of reference directions, which means provide determination of orientation of a given segment relative to the reference directions. Data from sensors 4, means 5 for determination of reference directions and, when necessary, from devices 8 of interaction of a user with the virtual space objects are processed for determination of the user's orientation and position as a whole on the basis of particular values of angles between segments, and orientation of a main segment whereat means for determination of reference directions, relative to the reference directions, are arranged. Obtained data are used for displaying user's movements in real time, or representation for a user of virtual space that corresponds to his/her viewing field that varies according to movements in real space.
