Long-distance relationships are much more common than most of us probably realize. In the 1980s, around 700,000 Americans were in long-distance marriages, but by 2005 that number had climbed to 3 million. Likewise, estimates say that up to half of college students are currently in a long-distance relationship, and 75 percent have been in one at some point. With all those lovelorn beaus out there, gadgets that make it easier to love at a distance could be huge.

That's where the Connections Lab is looking to shine. "If people can't physically be together, we're hoping to create the next best technological solutions," lab head Dr. Carman Neustaedter said in a press release.

So what have they come up with? Their biggest claim to fame has to be Flex-N-Feel gloves, which are designed to simulate touch. One glove "flexes," the other "feels," so that the movements of one glove are transmitted over the internet to activate tiny vibrating motors all over the other glove. In the real world, this could let one partner give the other the feeling of holding a hand, touching an arm, or doing something more intimate.

The lab is also using videoconferencing and virtual reality to give a sense of a loved one's presence. Remote employees are already using telepresence robots in offices, but one Connections Lab researcher found that using them in long-distance relationships helped couples maintain the kind of spontaneity and subtlety that texts and video chats simply can't. Another engineer created a system called Be With Me that lets one partner accompany the other during their day-to-day, simply by wearing a VR headset that connects to a 360-degree camera on a phone. The world might be getting bigger, but technology keeps bringing us closer together.
