The invention provides a tactile information transmission system or an
information perception apparatus that transmits information by means of
various motions of a presenter in two directions, as well as a small
driving force generation apparatus that drives a presenter suitably. Thin
plate-like magnets are provided on a base, and generate magnetic fields
perpendicularly. A perception unit is supported above the magnets movably
in the horizontal direction. Plural coils are fixed on the perception
unit, some coils are provided so as to cross in X direction and the
residual coils are provided so as to cross in Y direction. By controlling
supplied current or applied voltage, the perception unit is driven
arbitrarily in an XY plane. A user places a finger on the perception unit,
recognizes the motion of the perception unit, and obtains information. The
motion signal for driving the perception unit can be supplied from another
information processing apparatus, and the perception unit is moved in
correlation with the image information displayed on a display.
