Interaction strength using virtual objects for machine control

A method of using virtual force applied by a hand in a three-dimensional (3D) sensory space to a virtual object with a virtual mass in a virtual space, the method including:

• creating a manipulation point of the hand responsive to, a virtual grasp action between fingers of the hand and a palm of a hand or a swiping action of the hand wherein the created manipulation point remains within a proximity of the hand as the hand moves throughout the 3D sensory space;
• selecting a virtual object as the created manipulation point of the hand comes within a proximity of the virtual object or a manipulation point of the virtual object, wherein at least the fingers of the hand are not within a zero-proximity distance from the virtual object or the manipulation point of the virtual object;
• and
• causing motion of the selected virtual object in response to:
• movement of the manipulation point of the hand;
• or
• escalation of the virtual grasp action or the swipe action of the hand.

A non-transitory computer-readable recording medium having a program for using virtual attraction between a hand in a three-dimensional (3D) sensory space and a virtual object in a virtual space recorded thereon, the program, when executed by one or more processors, causing the one or more processors to perform a method including:

• creating a manipulation point of the hand responsive to a virtual pinch action between two fingers of the hand wherein the created manipulation point remains within a proximity of the hand as the hand moves throughout the 3D sensory space;
• selecting a virtual object as the previously created manipulation point of the hand comes within a proximity of the virtual object or a manipulation point of the virtual object, wherein at least the two fingers of the hand are not within a zero-proximity distance from the virtual object or the manipulation point of the virtual object;
• and
• causing motion of the selected virtual object, in response to:
• movement of the manipulation point of the hand;
• or
• escalation of the virtual pinch action of the hand.
