When you’re in the same room with a friend, but one of you doesn't have a chatting program installed and running, it can be pretty difficult to share the link that you are currently browsing. However, the guys from Google seem to have found an answer to this problem with their new (still experimental) browser extension called Google Tone which lets you use sounds to share URLs.
The way this innovative solution works is actually pretty simple and efficient. You install the extension on your Chrome browser and whenever you find a link and want to share with those around you, you click on the Google Tone icon. Everyone else who uses Google’s Tone and is within ear shot will be able to visit the webpage you’ve shared without having to type in the address. This new tool uses a dual-tone multi-frequency signaling system, similar to the one used in telephony.
Of course, in order to use this new extension you will need to be logged into your Google account, so that the other persons can see where the link is coming from and decide if they actually want to see it or not. Furthermore, the sound needs to be loud enough to be picked up by your friend’s microphone in order for this to work.
