“Have you ever tried to write an SMS while riding a saber-tooth horse to fight a horde of monsters?”

So asks the cheeky video to promote a slap bracelet that’s designed to exchange a touch between those wearing the wristband. For most of us, the answer to the question is a resounding no.

But hear the guys from Woodenshark out. They believe TapTap is a simple and powerful way for two people to remotely exchange a warm gesture, a touch on the wrist. They’re among those trying to build products to convey personal warmth through our gadgets.

“What we try to focus on is emotions, and emotions are typically invaluable in terms of money and user experience,” said Dmitry Gorilovsky, the founder of Woodenshark.

TapTaps are sold in pairs. If one is tapped, the other will vibrate. It’s a way to let a special someone know you are thinking about them.

Only in the 21st century do you have to pay $130 to receive a hug, a cynic would say.
