4. Beaulieu does not disclose an actuator having a player icon displayed
on a top surface within in the boundaries of the actuator by the display screen,
wherein when the actuator is moved in a direction normal to the top surface by a
player’s own power, the actuator is resiliently urged upward and provides tactile
feedback to a player’s finger.
5. Diederiks teaches a relief generator for dynamically generating a
relief on a display screen (Diederiks ¶ 4).
6. The relief generator consists of layer 202 of transparent piezo
electrical material comprising a plurality of piezo electric elements which may be
individually addressed to form a relief at locations which coincide with the
graphical representations of, for example, a button (Diederiks ¶ 21-22).
7. Diederiks further teaches that the relief generator is capable of
dynamically generating changes in the relief in response to user actuations, so as
to provide tactile feedback. For example, when a user presses a graphical button
with sufficient force, the relief generator removes or even converts an initial
protrusion into a depression, giving a clear indication to the user that the button is
pressed (Diederiks ¶ 12).
8. Diederiks explains that the initial touching of the user’s finger 401
causes a depression of the button 104 which in turn causes a small voltage
generated by the piezo electrical material. This voltage is opposite to the voltage
applied to the button for generating the protrusion. This latter voltage may be
maintained or even increased temporarily for generating a resistance, and
suddenly lowered, removed or even inverted when the exerted force exceeds the
