In a bid to enhance long-distance relationships, Japanese researchers have developed a kissing machine that lets users 'transmit the feeling of a kiss' over the Internet.
The device, created by the Kajimoto Laboratory at the University of Electro-Communications, consists of a hardware receptacle that is placed into the mouth.
Then the software records your tongue motion and transmits them to the other connected device, which moves accordingly.
The lab is still working on recreating other elements of a kiss other than tongue movement - like breathing and the sense of taste.
"The elements of a kiss include the sense of taste, the manner of breathing, and the moistness of the tongue. If we can recreate all of those I think it will be a really powerful device," the Sydney Morning Herald quoted them as explaining in a video showcasing the device prototype.
"If you have a popular entertainer use this device and record it, that could be hugely popular if you offer it to fans," they concluded.
