So Appy Together
Kvedar’s not alone. Nearly every developer I spoke with said that Siri may be a game changer when it comes to mobile health. And behavioral scientists and designers of these products are already busy building algorithms to implant into Siri’s brain. In so doing, they’re probing our psyches to find ways to get us to trust and build relationships with these tools.
Behavioral scientist Betsy Barbeau is one of these digital “neurosurgeons.” As the chief science officer at Healthrageous, the commercial arm that grew out of the Center for Connected Health, she’s designing artificial intelligence technology that will better understand us humans. People who sign up for Healthrageous are guided by a virtual coach that’s been programmed using a technique called motivational interviewing. The goal is to create an empathetic, almost therapeutic relationship between the patient and the technology. “There’s no wagging of the finger, there’s no, ‘You blew it this week,’” Barbeau explains. “It’s the idea that someone is watching you, checking in, and giving you an ‘atta girl’ if you met your goals.” That “someone” is actually a something, but who’s counting? I ask Barbeau what would happen if I lied to the coach about my calorie intake. She laughs. “Well, I could see it saying something like, ‘I see your activity level has been very high but your weight level hasn’t been changing.’ It would be an opener for further reflection.”
Knowingly cultivating an empathetic relationship with your smartphone is downright creepy. But the thing is, virtual coaches actually work. A study in the Journal of Medical Internet Research, published in January and coauthored by Kvedar and Timothy Bickmore, a computer science professor at Northeastern University, found that having a virtual coach can steer people toward better health. In the study, they provided 70 adult Bostonians with pedometers and access to a website where they could track their steps. Half of them were also able to work with an animated coach on the site that offered personalized feedback on how they were doing. At the end of the experiment, those who were coached walked an average of a half mile more per day than those who weren’t.
Bickmore says these programs are trying to replicate the communication between doctors and patients. The coach can have a caring face, he explains. “We shift its pitch and slow its voice down so it sounds more concerned. We’re trying to acknowledge the emotional dimension of what’s going on.” He hasn’t yet researched the degree to which people feel bonded to these coaches, but he’s hopeful. “A lot of time at the end of the studies,” he says, “we have participants who don’t want the study to end, and don’t want us to take the character away.”
MOSS, THE HEAD OF THE New Media Medicine Group, says it’s best to think of our phones not as coaches but as “partners” working alongside us. He says it’s smart to begin thinking about the emotional interactions we have with our phones now, before we get to the point where we’re breaking up with devices or wondering why they aren’t returning our calls. But he also cautions that the fear that we’ll become cyborgs shouldn’t deter us from charging full bore into the digital health space. For one thing, he argues, the more data we collect about ourselves, the more it can be used to help feed into the population, giving us a far more accurate way to shape public health policy.
I ask Sherry Turkle, the MIT professor, if she can foresee a day when she views her phone as a partner.
She pauses. “I get migraines,” she says — the close-the-drapes kind that keep her in bed for days. If a phone had the capacity to measure her temperature, pupil dilation, and galvanic skin response — three things that indicate the onset of a migraine — and then tell her to take a pill to fend off the massive headache, she would absolutely want it. It would be akin to having a hero rescue a damsel from the path of an oncoming train.
