How do you train people to talk to other people?  For some professions, like nursing, communicating with others is a critical part of the job.   Computer scientist Ben Lok developed software for nursing students to interview and examine a “virtual patient.”  The patients speak like actual people, have back stories, and don’t necessarily share information easily.  The son of a pipeline engineer and a nurse, Lok moved to the Tulsa from Malaysia when he was 5 years old.  He credits his father’s prescient interest in computers - and an Atari game - with his career path.  Lok’s company, Shadow Health, has plans to develop applications for other occupations that rely on face -to-face communication.
