In a method for controlling an orienting/positioning system, the orienting
system comprises at least one sensor means, an external motion detection
device for detecting an externally-caused motion in the environment of
the sensor means and actuator means for controlling an orienting and/or
positioning action of the sensor means. The method comprises the steps
of: (a) Evaluating pre-action output information of said sensor means in
order to detect the position of a pattern in the input space of the
sensor means; (b) Deciding on a targeted post-action position of said
pattern in the input space of said sensor means; (c) Defining a command
for the actuator means by mapping any deviation of the pre-action
position and the targeted post-action position in the input space
coordinates of the sensor-means to actuator control coordinates using a
predefined mapping function; (d) Orienting/Positioning the sensor means
by the actuator means according to the defined command in order to carry
out an orienting/positioning action; (e) Detecting the real post-action
position of the patterns in the input space of said sensor means; (f)
Detecting external motion of the pattern; and (g) Adapting the mapping
function used in step (c), wherein steps (a) to (g) are repeated using
the respectively adapted mapping function. An output signal from the
external-motion detection device can be used to control the adaptation
step (g).
