A user selects a content item that he wishes to send. He then performs a gesture to specify a direction toward which the content item is to be sent. For example, he pretends to “throw” his portable communications device toward the West. To receive the content item, potential recipients also make gestures that specify receiving directions. For example, a recipient pretends to “catch” a ball thrown from the East. If the sending and receiving directions are compatible, then the content item is sent from the sender's device to the recipient's device. Enhancements to the basic scheme described above can be made to, for example, specify a dispersion angle for the sending or receiving directions or to include other restrictions so that, for example, only intended recipients can receive the content even if other potential recipients are in the specified sending direction and make appropriate receiving gestures.
