DISAMBIGUATION OF MULTITOUCH GESTURE RECOGNITION FOR 3D INTERACTION

摘要

A multitouch device can interpret and disambiguate different gestures related to manipulating a displayed image of a 3D object, scene, or region. Examples of manipulations include pan, zoom, rotation, and tilt. The device can define a number of manipulation modes, including one or more single-control modes such as a pan mode, a zoom mode, a rotate mode, and/or a tilt mode. The manipulation modes can also include one or more multi-control modes, such as a pan/zoom/rotate mode that allows multiple parameters to be modified simultaneously.
