A planar motion device is also described for crawling over a planar surface.

In a two-dimensional plane motion if the 2-point movement of the solid is known, the movement of the entire solid is determined

Preferably, the modulation scheme is a QAM scheme.

The invention relates to a device for translating a biaxial pivotal motion of a gear-shift lever (2) into a planar motion of a gear-shift lever position transmitter.

The direction of motion is in the plane.

Motion parallax is used to separate foreground objects from the background.

A bearing surface parallel to a plane of the waveguides prevents movement out of the plane and allow movement along the bearing surface parallel to the plane.

The first mechanical part interlocks with the second mechanical part by motion in a first plane (40) in order to resist motion perpendicular to said first plane.

The example method may also include determining a data movement plan and executing the data movement plan.

The motion detector generates a motion detection plane that is substantially perpendicular with respect to the first outer surface.

The motion of at least one of the identified background image regions is estimated to identify those background image regions affected by global motion.

Movement in the X-Y direction, angular movement and rotational movement, parallel to the movement of the plane of the surface of the gaming table is enabled.

In identifying foreground-objects, semantically significant and semantically insignificant movement (e.g., non- repetitive versus repetitive movement) is differentiated.

Each parallelogram has two sides parallel to the plane of the movement.

The foreground regions comprise the at least one moving object.
