"What are drones but flying smartphones, one app away from indispensable? We could see drones accompanying early morning joggers, taking sport, wildlife and other photography to a new level," said Ryan Calo, an expert in law and emerging technology at Stanford University's Center for Internet and Society.
Civil Rights Awareness
Civil liberties groups have a more guarded view of the likely darkening of American skies by unmanned aircraft.
The Electronic Frontier Foundation (EFF) warns drones can intercept messages on wireless networks, monitor up to 65 people and carry eagle-eyed technology that can identify the brand on a carton of milk from 18,000 meters.
When a drone was used to assess damage from an earthquake in Italy in September, it also stumbled across a marijuana plantation and duly identified those individuals responsible.
Similarly, while U.S. Customs deploys drones to patrol the border, their unmanned aircraft are sometimes used to help local police.
"Rules must be put in place to ensure that we can enjoy the benefits of this new technology without bringing us closer to a surveillance society in which our every move is monitored, tracked, recorded and scrutinized by the government," the American Civil Liberties Union has warned.
The potential implications of widespread drone use mirrors the problems faced by Google, which was fined $7 million on Tuesday after it emerged that vehicles snapping photos for its Street View images were also gathering information from private Wi-Fi hotspots.
The FAA meanwhile estimates that more than 7,000 small unmanned aircraft will dot American skies in the next five years.
When U.S. airspace opens up in October 2015, drones will be used in six test locations. The tests are designed to help the FAA draw up rules governing the use of unmanned aircraft.
Currently drones are allowed to fly on public service missions -- used by fire brigades or customs for example -- or for recreation, provided the smallest are visible to the naked eye.
Thirty U.S. states are working on legislation to limit the use of drones, a move welcomed by the ACLU.
The rights group has argued that states should demand law enforcement seek warrants for drone use and prohibit the publication of images from drones or equipping them with weapons such as tasers, rubber bullets and tear gas.
