Patent ID: 8630462

Claim:
An apparatus, comprising: an acquisition module configured to receive a first position datum associated with a position of an object at a first time, the acquisition module configured to receive a second position datum associated with a position of the object at a second time after the first time; an area definition module configured to define a focal point of the first position datum, the area definition module configured to set an area surrounding a first object position associated with the focal point of the first position datum as a dead-zone at substantially the first time; a comparison module configured to determine whether a focal point of the second position datum is within the area surrounding the first object position substantially at the second time, the area definition module configured to set an area surrounding a second object position as the dead-zone at substantially the second time if the focal point of the second position datum is outside the area surrounding the first object position, the second object position being associated with the first object position and the focal point of the second position datum; and a rendering module configured to maintain a position on a display of a graphic if the focal point of the second position datum is within the area surrounding the first object position.
