"Hi, I'm Ellie."


Post-traumatic Stress Disorder is a mental illness that science is slowly becoming familiar with, but has a long way to fully understand. Nearly 20% of veterans from the war in Iraq and Afghanistan suffer from PTSD, and a greater percentage from the Vietnam War suffer as well. There has been and still is a stigma surrounding mental illness in the US, and one of the main problems facing those with an illness is the fear of admittance. Those who suffer may not even know they have a mental illness, or don’t want to admit to needing help. This apprehensiveness and reluctance to talking about mental health is one of the reasons why we are so behind in understanding mental illnesses. However, the University of Southern California’s Institute for Creative Technologies has developed a “virtual therapist” to help identify patients with PTSD, anonymously.

           
USC’s Creative Institute debuted Ellie, a virtual therapist, who was created to detect verbal and nonverbal indications of PTSD in veterans. Ellie allows veterans to be screened anonymously for PTSD, with her asking common leading questions and gathering information. They key to Ellie’s success is that she is designed to not judge anyone on the information they tell her, which allows patients to open up to her truthfully and fully. The technology bases its questions off of facial expressions, eye movements, and voice quality to determine whether or not the patient has PTSD. Co-creator Professor Louis-Philippe Morency insists that the anonymity and lack of judgment from Ellie is why the patients being screened are so willing to talk and open up. As of now, Ellie is only able to screen patients, not treat them. Treatment is carried on by a real doctor who bases plans off of the data gained from the screening.

            Although Ellie is not a solution or treatment for PTSD, she opens a large window of opportunity for researchers and psychologists to study an even larger group of patient with PTSD. In addition, she offers veterans an easier and more comfortable way to get help if they are suffering. Currently, Ellie is only being used to screen US veterans, but hopefully in the near future her technology can be used for any types of PTSD or mental illnesses. This would help psychologists and researchers better understand mental health disorders because of the safe and calm environment patients feel while being screened by Ellie.

  1. This is wonderful to see. Many people have been saying that things like this will be presented 'soon' so it is good to see that it is starting to finally be the time where more advanced technologies are being presented, especially ones like this. I have to say, it was a bit odd just watching the video, not for any particular reason, but just mainly because the AI seemed nearly sentient.

  2. This is such an innovative creation. The stigma around mental health is so debilitating and it is encouraging to see people who want to take action to decrease it. It is ironic that many people think technologies may be the reason for many people's mental illnesses but this is using technology in order to help mental illness. It seems like the inventors are truly motivated by the desire to help mental illness and hinder stigma. This is a great invention, thank you for sharing!

  3. This is an awesome idea! I have seen technology being used to treat PTSD before, but never to diagnose it. Having lived amongst family members dealing with PTSD I know how hard it can be for them to cope sometimes or truly share their thoughts. This, coupled with VR therapy, has potentially monumental effects on the stigma surrounding PTSD, as well as promoting healthy coping mechanisms.
