There's an app that needs you: the rise of mobile crowdsourcing

Story highlights

  • Crowdsourcing apps are changing everything from the way we travel, to the way we work, to the way we gather information
  • The earliest example of crowdsourcing was the Oxford English Dictionary which relied on volunteers in the 19th century
  • Crowdsourcing has been popular in Europe and the US for almost a decade
  • In Asia, where personal relations in business are more important, the phenomenon has been slower to take off

(CNN)From avoiding traffic jams, to analyzing pedestrian flow patterns, to finding the best public toilet in town, crowdsourcing apps are showing that many smartphones make for light work.

With thousands of mini-reports coming in from around the internet, a mosaic of information can form a larger picture that can be used for many different purposes, from meteorology to car-sharing.
Using the intelligence of a vast interconnected organism, however, is nothing new: the venerable Oxford English Dictionary may in fact be the earliest example of crowdsourcing.
In the mid-19th century it made an open call for volunteers to log words and provide examples of their usage. Over a 70-year period, it received more than six million submissions.
Today, crowdsourcing is used in investing, in creative work and in funding start up projects.
As with all good ideas, gaining a critical mass is a crucial element to its success. Even runaway hits such as BlaBlaCar -- the AirBnb of car travel -- initially struggled to gain a significant number of users.
But such incidents as a French transport strike in 2007 -- BlaBlaCar gained precious media coverage for being very much in business during the shutdown -- and the Icelandic volcano that grounded aircraft in 2010 played well for the company.
The wide availability of smartphones now makes it easier than ever to devote them to data gathering, with or without actual human intervention.
The Rainforest Connection transforms recycled cellphones into solar-powered surveillance devices that can detect illegal logging: placed high up in the forest canopy, they listen out for the sounds made by chainsaws and trigger immediate intervention by authorities.
In New York, a start up called Placemeter encourages citizens to suction-cup an old Android phone or an iPhone to a window, to send over a video feed of the street below. Placemeter uses the data - which they assure is completely anonymous and is never stored -- to infer pedestrian traffic patterns. This helps businesses market better and consumers can be made aware of waiting lines at shops or museum before even getting there.
Participants receive up to $50 per month, depending on the quality of the view from their window.
Crowdsourcing apps have been quick to gather pace in the U.S. and Europe -- where dealing in a marketplace with strangers is commonplace -- but slower in Asia where connections are still important.
While some strong start ups are doing well in the region -- freelancer platforms such as Coconala and Lancer in Japan and Zhubajie in China -- crowdsourcing is still in its infancy.
"The challenge for crowdsourcing in Asia is that people tend to be more risk averse," says Ping Wong of the Hong Kong Internet Society. "They want to work with people they know or get a referral from friends.
"This cultural difference may take time to iron out before crowdsourcing can really take off in Asia."
In the meantime, European users can't get enough of apps such as Blablacar which are changing the public transport landscape. With a carefully designed service that calibrates the petrol money for spare seats in private cars, the app's owners say they are seeing it grow as a social phenomenon.
BlaBlaCar's Alec Dent told British media the company has even noticed spikes in searches for rides to Manchester before United home games.
"We thought it would be interesting to test the old joke that a lot of Manchester United fans live in Surrey," he was quoted as saying.
"And sure enough, there is a pattern of rides to and from Old Trafford around match days from the London area, especially Surrey."
