Abstract
A method for providing telepresence by employing avatars is provided. The method includes steps of: (a) a corresponding location searching part determining a location in a first space where an avatar Y′ corresponding to a human Y in a second space will be placed, if a change of a location of the human Y in the second space is detected from an initial state, by referring to (i) information on the first space and the second space and (ii) information on locations of the humans X and Y, and the avatar X′ in the first and the second spaces; and (b) an avatar motion creating part creating a motion of the avatar Y′ by referring to information on the determined location where the avatar Y′ will be placed.
