Peggy Wu is a Principal Scientist at Raytheon Technologies Research Center (RTRC), the research arm of Raytheon Technologies, a fortune 50 aerospace company. Peggy leads Human Machine Interactions, which combines cognitive science with machine learning and other advanced technologies. In this talk she will discuss two topics: The first topic is the results of a pilot testing program comparing AR, videos, and traditional instruction in an Aerospace Manufacturing Repair and Overhaul (MRO) training scenario at the Pratt and Whitney Columbus Engine Center.  The second topic is a Department of Energy Advanced Research Projects Agency (ARPA-E) funded program performed in partnership with Iowa State University called SCOTTIE. The objective of SCOTTIE is to empirically evaluate team communication and collaboration to quantify how they differ when performed under three different conditions: 1) in person 2)using  standard teleconference tools and 3) using a VR based tele-collaboration environment.
