Holding and releasing virtual objects
Techniques and devices for determining how to present the release of the virtual object based at least in part on received sensor data is described herein. For example, when the hardware and/or software determines that the virtual object is to be released, the hardware and/or software may calculate one or more of a velocity of the object (e.g., speed and direction), a position at which the virtual object is to be released, a trajectory of the virtual object from the position of release to the landing point of the virtual object, a landing location of the virtual object, and/or the like. The hardware and/or software may then present the virtual object being released according to this determined information.
