A reticle of a projectile weapon aiming system such as a riflescope includes a primary aiming mark adapted to be sighted-in at a first selected range and further includes a plurality of secondary aiming marks spaced apart below the primary aiming mark. The secondary aiming marks are positioned to compensate for ballistic drop at preselected incremental ranges beyond the first selected range, for a selected group of ammunition having similar ballistic characteristics. Angles subtended by adjacent aiming marks of the reticle can be adjusted by changing the optical power of the riflescope, to thereby compensate for ballistic characteristics of different ammunition. In some embodiments, the reticle includes a set of windage aiming marks spaced apart along at least one secondary horizontal axis intersecting a selected one of the secondary aiming marks, to facilitate compensation for the effect of crosswinds on the trajectory of the projectile.

A user, a manipulator such as a hand, and at least one entity such as a virtual or augmented reality object are in an interface such as a 3D environmental interface. The manipulation distance is the distance between a reference feature of the user and a manipulation feature of the manipulator. The entity distance is the distance between the reference feature and an entity feature of the entity. When the manipulation distance becomes greater than the entity distance, the entity is caused to fade, disappear, move out of the way, shrink, etc. so as to be less of an obstruction to the user's field of view, for example to avoid obstructing more distant entities. Other factors than the manipulation distance and entity distance may be considered in determining whether to reduce the obstructivity of the entity, and exceptions to the obstruction relation may be considered.
