BOSTON (CBS) – Could a wagging tail that responds to your heart rate be the next big thing out of Japan?

On Sunday, a prototype of “Tailly” will make its American debut right here in Boston.

A Tailly prototype will be on display at the Artist’s Alley of Arisia ’13 at the Westin Boston Waterfront.

Here’s how it works: the tail is attached like a belt and it uses sensors on the inside of the belt to measure the user’s heart rate.

“Normally the tail hangs down, but when the user gets excited and their heart rate increases, the tail starts wagging, and when they calm down and their heart rate decreases, the tail swings slowly,” its makers said in a press release.

It’s not totally clear what exact purpose this tail serves.

It appears that Tailly is a combination of a toy, a fashion accessory, and a gadget.

Tailly comes in white, black, brown, or grey.

“Tailly is fun to wear to parties, while out with friends or playing with kids,” the creator’s Kickstarter page says. “You could even wear Tailly on a date and express your true feelings through the wagging tail. Even better, your partner could also wear one for the both of you to add a level of subconscious communication between the two of you.”

The company’s Kickstarter page has raised the equivalent of $19,000. They’re trying to raise $100,000.
