This paper examines the problem of geometric constraints acquisition of a planar motion through a line-geometric ap- proach. In previous work, we have investigated the problem of identifying point-geometric constraints associated with a motion task which is given in a parametric or discrete form. In this paper, we seek to extend the point-centric approach to the line-centric approach. The extracted geometric con- straints can be used directly for determining the type and di- mensions of a physical device such as mechanical linkage that generates this constrained motion task.
