Researchers at Northeastern University have developed a virtual nurse and exercise coach that are surprisingly likable and effective—even if they're not quite as affable as the medical hologram on Star Trek. In fact, patients who interacted with a virtual nurse named Elizabeth said they preferred the computer simulation to an actual doctor or nurse because they didn't feel rushed or talked down to.

A recent clinical trial of the technology found that Elizabeth also appears to have a beneficial effect on care. A month after discharge, people who interacted with the virtual nurse were more likely to know their diagnosis and to make a follow-up appointment with their primary-care doctor. The results of the study are currently under review for publication.

"We try to present something that is not just an information exchange but is a social exchange," says Timothy Bickmore, associate professor in Northeastern's College of Computer and Information Science. Bickmore led the research. "It expresses empathy if the patient is having problems, and patients seem to resonate with that."  the rest
