To try to get a glimpse of the everyday devices we could be using a decade from now, there are worse places to look than inside the Future Interfaces Group (FIG) lab at Carnegie Mellon University. During a recent visit to Pittsburgh by Engadget, PhD student Gierad Laput put on a smartwatch and touched a Macbook Pro, then an electric drill, then a door knob. The moment his skin pressed against each, the name of the object popped up on an adjacent computer screen. Each item had emitted a unique electromagnetic signal which flowed through Laput's body, to be picked up by the sensor on his watch. The software essentially knew what Laput was doing in dumb meatspace, without a pricey sensor needing to be embedded (and its batteries recharged) on every object he made contact with.

If you want to set up a connected home, you've got two options. You can buy a bunch of smart gadgets that may or may not communicate with other smart gadgets. Or you can retrofit all of your appliances with sensor tags, creating a slapdash network. The second is a hassle. Before long, though, you might have a third choice: One simple device that plugs into an electrical outlet and connects everything in the room.

John Essey and family live in a modest, two-story home on a tree-lined street in the suburbs north of Pittsburgh. From the outside, it looks like any other house in the neighborhood, but this house has a brain. Doors unlock, [it] kinda sets the mood for the rest of the house too, turns on lights, sets the thermostat accordingly," Essey says. Essey is an engineer at Uber and an early adopter of the Internet of things. He can control his lights with his Amazon Echo or an array of touchpad sensors he's installed throughout the home. Sensors tell him when there's water in the basement or a leak under the sink. While Essey's setup might sound a little like science fiction it's a prototype of the future. Some critics are worried these devices won't be secure and that companies will use them to spy on us to make money. Gierad Laput, a Ph.D. student at Carnegie Mellon University, says as the Internet of things becomes more engrained in our daily lives, there are a couple of ways people are turning ordinary homes into smart homes. "One way is basically to buy all the appliances, smart oven, smart dishwasher, smart microwave, smart toaster, all these things," Laput says. But that stuff is really expensive. Smart refrigerators can cost $3,000 or more. And Laput said those devices don't always talk to each other, especially if they're made by different manufacturers. The other way is to get sensors, and put them on everything you want to monitor. "But then those get really unwieldy and you've got all these things sticking around and they look ugly and socially obtrusive," Laput says. So Laput and his team wanted to see if they could build just one sensor that could monitor a whole range of activity in a room. The board senses about a dozen different facets of its environment: vibrations, sounds, light color and so on. The sensor communicates wirelessly with a computer, which interprets everything it picks up. Laput demonstrated how the sensor works by turning on a blender. Laput turned on a light, and the screen said, "light on." Laput says he imagines both domestic and commercial applications for such a sensor. It could tell you that you left your stove on or that you're almost out of paper towels in the bathroom at the restaurant you own. But critics say there's a catch. "Surveillance is now the business model of the Internet.
