CONTROLLING MOVEMENT OF A DEVICE

Apparatuses and methods for movement control of a device are disclosed. The apparatus comprises memory for storing information of patterns covering sectors of the area indicating whether the patterns have at least one item relevant to movement in the area. The information has been configured based on determination of at least one pattern that has at least one item relevant to movement in the area, division of the determined at least one pattern into smaller patterns, determination of at least one of the smaller patterns with at least one item relevant to movement in the area, and repeat of the division until predefined smallest pattern size is reached. A processor is configured to determine whether a search path between first and second locations extends through at least one pattern having at least one item relevant to movement in the area, and to selectively use a path finding algorithm to determine a path of movement within at least one pattern with relevant items through which the search path is determined to extend.
