The system of claim 1 , wherein the virtual cone comprises a proximal end, and the hardware processor is programmed to anchor the proximal end to at least one of the following locations: a location in-between the user's eyes, a location on a portion of a user's arm, or a location on a user input device.

14. The system of claim 1 , wherein the virtual cone comprises a distal end, and the hardware processor is programmed to scan for collisions with one or more objects within the distal end of the virtual cone.

15. The system of claim 1 , wherein the virtual cone comprises a proximal end, a distal end, or a depth, and the hardware processor is programmed to anchor the proximal end, the distal end, or the depth of the virtual cone based on: the contextual features, user input, a body gesture, a body pose, a direction of gaze, or a voice command.

16. The system of claim 1 , wherein the user interaction with the collided object comprises one or more of:

a selection of the collided object;

a movement of the collided object;

display of a menu or toolbar associated with the collided object; or

a game operation on a virtual avatar in a game.
