Abstract: An apparatus includes an acquisition module, an area definition module, a comparison module and a rendering module. The acquisition module is configured to receive a first position datum and a second position datum associated with a position of an object at a first time and a second time, respectively. The area definition module is configured to set an area surrounding a first object position associated with a focal point of the first position datum as a dead-zone. The comparison module is configured to determine whether a focal point of the second position datum is within that area. If yes, the rendering module is configured to maintain a position on a display of a graphic. Otherwise, the area definition module is configured to set an area surrounding a second object position associated with the first object position and the focal point of the second position datum as the dead-zone.
