They say the vast majority of communication is done physically rather than verbally, but in the realm of technological advances we seem to have rather neglected the transmission of physical contact. Thankfully, there's always Japan to provide us with off-the-wall innovations, this latest one being a kiss transmission device that will record, relay, and -- if you wish it -- replay your finest tongue gymnastics. It's the height of simplicity at the moment, with a plastic implement taking input from one person's mouth and conveying it to a second box, intended to be gobbled up by the recipient of this techno-affection, who may respond in kind or just sit back and enjoy the thrill of it. The researchers sagely point out that there's more to be done, as the sense of taste, manner of breathing, and moistness of the tongue are all important aspects of a kiss that have yet to be recreated. Once they do get their kiss transmitter to v2.0, however, they envision a pretty neat market for it in reselling kiss replays performed by celebrities. For now, you can see a celeb-free video demo after the break.
