Virtual-projectile delivery in an expansive environment

A method enacted on a server to support an experience wherein a virtual projectile is launched by a virtual-projectile launcher of a first player, the method comprising:

• receiving a hit signal from a device worn by the first player, the device being configured to output the hit signal on determining, pursuant to receiving an indication of launch of the virtual projectile, that a recognized object is imaged in a projectile-delivery area;
• receiving a position of the device;
• receiving an orientation of a launch axis of the virtual-projectile launcher;
• receiving a position of a second player;
• and
• outputting a hit assignment on determining, pursuant to receiving the hit signal, that the recognized object and the second player are coincident at the indicated launch of the virtual projectile.

A device to be worn by a first player, the device comprising:

• a computer coupled operatively to a wireless transmitter and wireless receiver and configured to:
• receive an indication of launch of a virtual projectile by a virtual-projectile launcher of the first player,
• receive an image aligned to a launch axis of the virtual-projectile launcher,
• determine whether a recognized object is imaged in a projectile-delivery area of the image,
• output a hit signal to a server on determining, pursuant to receiving the indication of launch, that the recognized object is imaged in the projectile-delivery area of the image,
• output a position of the device to the server, and
• output an orientation of the launch axis to the server, the server being configured to receive a position of a second player and output a hit assignment if the recognized object and the second player are coincident at the indicated launch of the virtual projectile.
