Classification: CPC G | IPC G

Claim 0:
1. A method of positioning and revealing a control interface in a virtual or augmented reality, including:
causing display of a plurality of interface projectiles a first region of a virtual or augmented reality;
receiving input including first and second sensed positions of at least one hand sensed at a first time in a first reference frame of a three dimensional (3D) sensory space and at a second time in a second reference frame of the three dimensional (3D) sensory space using a sensor affixed to a head mounted device (HMD) worn by a user;
tracking movement of the at least one hand and motion of the attached sensor responsive to repositioning of the head mounted device and the attached sensor due to body movement;
calculating a transformation which renders the first position in the first reference frame and the second position in the second reference frame into a common reference frame;
interpreting motion of the hand in the common reference frame as user interaction with an interface projectile, including selecting and throwing the interface projectile in a first direction,
causing display of an animation of the interface projectile along a trajectory in the first directions to a place where it lands and an animation representing the movement of the hand tossing the interface projectile; and
causing display of the control interface blooming from the interface projectile at the place where it lands.
