Graduate student Janet Johnson is currently working towards her doctorate degree in Computer Science, while also conducting HCI research in the UCSD Design Lab, primarily focusing on XR (extended reality).

So, what is Johnson’s research?  Johnson conducts HCI research, primarily focusing on XR. As Johnson describes it, “XR is an umbrella term for augmented reality, augmented virtuality, mixed reality, and virtual reality.” She says to think of it as a spectrum where one end is the real world alone, the other is complete virtual reality, and everything in between is varying mixes of the two. Johnson’s research primarily focuses on this mixed middle ground. “The majority of my research focuses on how we can use mixed reality or extended reality to help a novice…get help from an expert.” She then poses the example of both surgery and CPR. Johnson’s research explores ways for an expert to provide instructions to the novice as if though they were in the same room. Her goal is to help bridge the distance between novices and experts, both physically and skill wise, while also decreasing the amount of time a person receives aid. “By the time a medical personnel arrives at the scene, it’s already been 7 to 10 minutes, so each minute counts for the person’s life,” she explains. “You don’t have time in that 10 minutes to train the people around to be able to do CPR or any other sort of resuscitation, same with surgery.” 

As Johnson continues to conduct her research in this field, she’s excited for what the future holds for this technology and the ways she can contribute to it.
