Abstract
A system and method is provided for using motion-capture data to control navigating of a cursor in a user interface of a computing system. Movement of a user's hand or other object in a three-dimensional capture space is tracked and represented in the computing system as motion-capture model data. The method includes obtaining a plurality of positions for the object from the motion-capture model data. The method determines a curved-gesture center point based on at least some of the plurality of positions for the object. Using the curved-gesture center point as an origin, an angular property is determined for one of the plurality of positions for the object. The method further includes navigating the cursor in a sequential arrangement of selectable items based on the angular property.
