Abstract
A method of controlling a virtual object within a virtual workspace includes recognizing a hand posture of an initial touch gesture directed to a touch-input receptor, and a mode constraint is set based on the hand posture. The mode constraint specifies a constrained parameter of a virtual object that is to be maintained responsive to a subsequent touch gesture. The method further includes recognizing a subsequent touch gesture directed to the touch-input receptor. An unconstrained parameter of the virtual object is modulated responsive to the subsequent touch gesture while the constrained parameter of the virtual object is maintained in accordance with the mode constraint.
