Jonathan Gratch

by Riley McMahon from United States

     Jonathan Gratch, a professor of computer science and psychology, has been working for years on the relationship between virtual reality, augmented reality and technology's ability to both respond to and effect human emotions.  A major facet of his research was discovering the driving forces of human emotion in order to grasp these tools and incorporate them into his work.  He discovered that emotions are a critical function in intelligent behavior, a "means for an organism to shift between competing goals, balance reactive and deliberate processing," (Gratch,
Computationally Modeling Human Emotion). Understanding some of the tenets of what drives humans, he was able to develop virtual machines that would lead to understanding and beneficial communication with real people.  His creations are designed to have empathetic reactions to people, respond to questions, read facial reactions of the participants in real time, and respond in supportive and useful ways.   He envisioned that these interactions could very well promote usefulness and more peaceful interactions with the participants as they returned to interacting with the outside world.

A major aspect of this research was a study where Elle was used to draw out soldiers with PTSD who were afraid to work on themselves with other humans. Gratch and his team discovered through this research and practice that there was success in people interacting with the virtual creation that was not seen in interactions with humans.

    The future of this technology contributes to a possibility of a world where useful, independent and socialized, artificially intelligent creations -- fully emotive and empathetic characters -- could be sent out into virtual environments, reacting to others, promoting nonviolence, aiding in mental illness -- sent out into environments that are sure to become more and more prolific in the years to come, as the tools of virtual reality become more available to all.  Gratch and his team's work strives for a world where our engagement with technology does create a better humanity -- grasping the profound implications and responsibilities of these tools, and using them to effect humans in positive, understanding and more beneficial ways.
