A handful of psychologists are testing a new service from a Silicon Valley startup called Limbix that offers exposure therapy through Daydream View, the Google headset that works in tandem with a smartphone.

SAN FRANCISCO Dawn Jewell recently treated a patient haunted by a car crash. The patient had developed acute anxiety over the cross streets where the crash occurred, unable to drive a route that carried so many painful memories.

So Jewell, a psychologist in Colorado, treated the patient through a technique called exposure therapy, providing emotional guidance as they revisited the intersection together.

But they did not physically return to the site. They revisited it through virtual reality.

Jewell is among a handful of psychologists testing a new service from a Silicon Valley startup called Limbix that offers exposure therapy through Daydream View, the Google headset that works in tandem with a smartphone.

It provides exposure in a way that patients feel safe, she said. We can go to a location together, and the patient can tell me what theyre feeling and what theyre thinking.

The service recreates outdoor locations by tapping into another Google product, Street View, a vast online database of photos that delivers panoramic scenes of roadways and other locations around the world. Using these virtual street scenes, Jewell has treated a second patient who struggled with anxiety after being injured by another person outside a local building.

The service is also designed to provide treatment in other ways, like taking patients to the top of a virtual skyscraper so they can face a fear of heights or to a virtual bar so they can address an alcohol addiction.

Backed by the venture capital firm Sequoia Capital, Limbix is less than 1 year old. The creators of its new service, including its chief executive and co-founder, Benjamin Lewis, worked in the seminal virtual reality efforts at Google and Facebook.

The hardware and software they are working with is still very young, but Limbix builds on more than two decades of research and clinical trials involving virtual reality and exposure therapy. At a time when much-hyped headsets like the Daydream and Facebooks Oculus are still struggling to find a wide audience in the world of gaming let alone other markets psychology is an area where technology and medical experts believe this tool can be a benefit.

As far back as the mid-1990s, clinical trials showed that this kind of technology could help treat phobias and other conditions, like post-traumatic stress disorder.

Traditionally, psychologists have treated such conditions by helping patients imagine they are facing a fear, mentally creating a situation where they can address their anxieties. Virtual reality takes this a step further.

We feel pretty confident that exposure therapy using VR can supplement what a patients imagination alone can do, said Skip Rizzo, a clinical psychologist at the University of Southern California who has explored such technology over the past 20 years.

Barbara Rothbaum helped pioneer the practice at the Emory University School of Medicine in Atlanta, and her work spawned a company called Virtually Better, which has long offered virtual reality exposure therapy tools to some doctors and hospitals through an older breed of headset. According to one clinical trial she helped build, virtual reality was just as effective as trips to airports in treating the fear of flying, with 90 percent of patients eventually conquering their anxieties.

Such technology has also been effective in treating post-traumatic stress disorder among veterans. Unlike treatments built solely on imagination, Rothbaum said, virtual reality can force patients to face their past traumas.

PTSD is a disorder of avoidance. People dont want to think about it, she said. We need them to be engaged emotionally, and with virtual reality, its harder for them to avoid that.

Now, headsets like Googles Daydream, which works in tandem with common smartphones, and Facebooks Oculus, the self-contained $400 headset that sparked the recent resurgence in virtual reality technologies, could bring this kind of therapy to a much wider audience.

Virtually Better built its technology for virtual reality hardware that sold for several thousands of dollars. Today, Limbix and other companies, including a Spanish startup called Psious, can offer services that are far less expensive. Limbix recently began offering its tools to psychologists and other therapists outside its initial test. The service is free for now, with the company planning to sell more advanced tools at some point.

After testing the Limbix offering, Jewell said it allowed patients to face their anxieties in more controlled ways than they otherwise could. At the same time, such a tool can truly give patients the feeling that they are being transported to different locations at least in some cases.

Standing atop a virtual skyscraper, for instance, can cause anxiety even in those who are relatively comfortable with heights. Experts warn that a service like the one offered by Limbix requires the guiding hand of trained psychologists while still in development.
