Slate: Stay out of my kitchen, robots

"Don't you have a machine that puts food into the mouth and pushes it down?" the Soviet leader Nikita Khrushchev sarcastically asked Richard Nixon in the now infamous Kitchen Debate of 1959. That memorable exchange took place at the opening of the American National Exhibition in Moscow, where Nixon, then vice president, went to promote the latest innovations of the decadent West.

Today, even the most Pampered Chef has no such food-pushing machine, but the quest to make our kitchens smarter continues unabated. Today's technologies are no longer the dumb, passive appliances of the 1950s. Some of them feature tiny and sophisticated sensors that "understand" — if that's the right word — what's going on in our kitchens and attempt to steer us, their masters, in the right direction. And if Khrushchev's rhetorical question sought to highlight the limitations of the consumer, today's attempts to build a "smart kitchen" highlight those of the culinary geek.

A recent article in the British magazine the New Scientist has brought attention to several such initiatives. Meet Jinna Lei, a computer scientist at the University of Washington who has built a system in which a cook is monitored by several video cameras installed in the kitchen. These cameras are quite clever: They can recognize the depth and shape of objects in their view and distinguish between, say, apples and bowls.

With this surveillance, chefs can be informed whenever they have deviated from their chosen recipe. Each object has a number of activities associated with it — you don't normally boil spoons or fry arugula — and the system tracks how well the current activity matches the object in use.

"For example, if the system detects sugar pouring into a bowl containing eggs, and the recipe does not call for sugar, it could log the aberration," Lei told the New Scientist. To improve the accuracy of tracking, Lei is also considering adding a special thermal camera that would identify the user's hands by body heat.

  • The case for separate beds

    The other night I slept on a twin bed in the guest room of the house I share with my husband and our two kids.
    It was the best night's sleep I've had in years.

  • Allergies are the real midlife crisis

    One of the biggest mysteries is why the disease comes and goes, and then comes and goes again. People tend to experience intense allergies between the ages of 5 and 16, then get a couple of decades off before the symptoms return in the 30s, only to diminish around retirement age.

  • treadmill-very-fast.jpg Tax deduction for a gym membership?

    April marks another tax season when millions of Americans will deduct expenses related to home ownership, children and education from their annual tax bill. These deductions exist because of their perceived value to society; they encourage behaviors that keep the wheels of the economy turning. So why shouldn't the tax code be revised to reward preventive health?

  • Boston doctors can now prescribe you a bike

    The City of Boston this week is rolling out a new program that's whimsically known as "Prescribe-a-Bike." Part medicine, part welfare, the initiative allows doctors at Boston Medical Center to write "prescriptions" for low-income patients to get yearlong memberships to Hubway, the city's bike-share system, for only $5.

  • A man with amnesia taught us how memories become personal

    Although not as celebrated as the late American amnesiac H.M., for my money K.C. taught us more important and poignant things about how memory works. He showed how we make memories personal and personally meaningful. He also had a heck of a life story.

  • Investing more money in tornado research would be a disaster

    This week, the U.S. House of Representatives passed a bill that would require National Oceanic and Atmospheric Administration funding to focus on improving forecasts of "high impact weather events" like tornadoes and hurricanes "for the protection of life and property and the enhancement of the national economy."

  • Hate With Friends, the fun new Facebook tool

    Hating movies, earworms, conventions of grammar, clothing brands, diet fads - you get the twinkle of pleasure without the glob of guilt, or the cold brush of fear. A Coldplay song doesn't know you hate it.

  • dog-sunglasses.jpg Do animals have a sense of humor?

    Right now, in a high-security research lab at Northwestern University's Falk Center for Molecular Therapeutics, scientists are tickling rats. Their goal? To develop a pharmaceutical-grade happiness pill. But their efforts might also produce some of the best evidence yet that humor isn't something experienced exclusively by human beings.

    Yet again, Facebook has spent a gaudy sum of money to buy a hot startup. This time, it's virtual reality pioneer Oculus VR, at a purchase price of $2 billion. And don't be surprised if Mark Zuckerberg continues on his buying spree.

  • 20140325-AMX-BARISTA251.jpg Coffee's third wave? The Apple to Starbucks' Microsoft

    Do you remember when Starbucks was cool? It opened in Seattle in the 1970s as a local specialty roaster, a trendy alternative to the prevailing generic swill. But the price of conquest is cachet. What was once novel — the warm décor, the gentle music, the faux-Italian lingo — has become banal. Today's coffee snobs would rather snort Sanka than set foot inside a Starbucks
