Abstract: <P>PROBLEM TO BE SOLVED: To provide an on-vehicle information providing system that does not give a feeling of incongruity to an observer, even when a positional relationship of an indication device and the observer is changed.  <P>SOLUTION: The on-vehicle information providing system 100 carries out body pressure measurements while an occupant is seated, estimates a physique and a seating position of the occupant by searching a human body database portion 103, and selects a human body vibration transfer function. By using detecting data of the human body vibration transfer function and vehicular movement, an estimation of head portion(especially, eyeballs) movement of the occupant is calculated. By using detecting data indicating the vehicular movement, moving amount in a pitch direction of an image indicating portion 106 is calculated. By using an estimated eyeball position and a position of the image indicating portion 106, relative displacement of both is obtained. The image indicating portion 106 is moved in the pitch direction so as to cancel movement of the image indicating portion 106 due to the moving amount in the pitch direction and the relative displacement. Therefore, for the occupant, an indication screen is seen as if the screen is stopped in a space corresponding to remote static scenery.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
