8. A method comprising: a detector of a gestural control system receiving absolute three-space location data of an object within a coordinate space of a room; a gestural interface of the gestural control system detecting a gesture from the received absolute three-space location data and generating a gesture signal corresponding to the gesture; and a graphics interface of the gestural control system controlling rendering of data on a display according to the gesture signal, wherein receiving absolute three-space location data comprises: detecting an evolving absolute three-space location of the object within the coordinate space of the room, wherein generating a gesture signal comprises: generating an updated gesture signal corresponding to the evolving absolute three-space location, and wherein controlling rendering comprises: updating rendering of data on the display according to the updated gesture signal.
9. The method of claim 8 , wherein the detecting includes detecting an evolving orientation of the object.
