a passage of Baker which discusses determining the speakers’
position by sampling audio signals in order to detect the largest
amplitude signal. Column 9, lines 29-33. This signal
information is then sent to an audio direction processor to
determine the direction to steer the camera.
Upon careful review, we fail to find that Baker discloses
speaker position data representing the position of the speaker as
coordinates in three dimensions. Baker discloses gathering
positional information about the speaker based on the strength of
the amplitude of the auido signals. Based on this information,
Baker discloses determining the direction to steer the camera by
correlating between the location of the microphone and the video
imaging system. Column 9, lines 29-38. As such, the
informational data disclosed by Baker does not represent the
position of the speaker in the form of coordinates having three
dimensions, but rather represents a correlation between the
microphone and video imaging system.
The Examiner also argues that Baker discloses speaker
position data representing the position of the speaker as
coordinates for a point in space since “[i]t is also possible, by
normal audio beam steering techniques, to select points between
microphones[.]” Column 10, lines 19-21. The Examiner states
