90. A system for selectable input based upon motion of a pointing device in relation to a region having a plurality of selectable characters, comprising: means for tracking the motion of the pointing device in relation to the region, wherein the tracked motion defines a device path comprising at least two selected positions; means for determining which of the selected positions along the device path correspond to at least one of the selectable characters; and logic for determining a characteristic motion of the pointing device that corresponds to at least one of the selected positions along the device path corresponding to at least one of the selectable characters.
