Dynamic user interactions for display control and manipulation of display objects
View Patent ↗The technology disclosed relates to distinguishing meaningful gestures from proximate non-meaningful gestures in a three-dimensional (3D) sensory space. In particular, it relates to calculating spatial trajectories of different gestures and determining a dominant gesture based on magnitudes of the spatial trajectories. The technology disclosed also relates to uniformly responding to gestural inputs from a user irrespective of a position of the user. In particular, it relates to automatically adapting a responsiveness scale between gestures in a physical space and resulting responses in a gestural interface by automatically proportioning on-screen responsiveness to scaled movement distances of gestures in the physical space, user spacing with the 3D sensory space, or virtual object density in the gestural interface. The technology disclosed further relates to detecting if a user has intended to interact with a virtual object based on measuring a degree of completion of gestures and creating interface elements in the 3D space.
