When the birds can communicate with each other via chirping, why cannot two cell phones do the same?
iPhone app Chirp can transfer images, text and web addresses between two phones that are in the audible range. The transfer takes place by means of sound signals that sound like they are made of a robotic bird.
The advantage is that you do not have to be through a complex configuration, such as having to pair the two mobile phones like Bluetooth to transmit information. The patented method of transmitting audio signals is created to function even in environments with a relatively high degree of background noise.
Easy to Use Chirp Data Communication
Chirp app is simple to use. After you’ve selected a picture or written a note or a URL, tap a large yellow button to start sending. After a few seconds with “bird noises” from mobile phone to mobile phone you will have sent the file on all iPhone devices nearby that have Chirp app open and can “hear” your data chirp.
It goes without saying that this is not an app that you would use to send confidential information. What you send can be received by all who have the app installed within listening distance. The app does not handle more than one cell phone chirping in a chorus, so it can only receive one cirp at one time. When we tried in tests to transfer data from two mobile phones simultaneously, it did nothing (niether message was received, so they obviously got jumbled and both chirps failed).
Chirping Requires an Internet Connection
Even though the transfer takes place by means of audio signals, you still need an internet or 3G connection for the app to work. If you capture an image to transfer by chirps it will be downloaded from the chirp server as this method makes sending images possible.
What happens when you choose to “chirp” a picture is that the image is uploaded from the mobile phone to the chirp servers. As soon as you press Chirp button to send the picture, you would have sent the link to the image (rather than the actual image) to the other phone. The Chirp app will then download the picture from this link and show it on the phone. It looks as if the image is transferred directly, but in reality we are talking about an exchange of links and an upload to Chirps servers of the image.
The recipient of a Chirp message may be offline when the message was received. The message will then be automatically downloaded as soon as you come online again.
The app is developed by Animal Systems, a company that has emerged out of the University College London (UCL). An Android version is expected soon.
