Joanna Alexander marked a significant milestone in XR history with her involvement in designing a virtual reality headset for Hasbro in 1993, a pioneering effort at the time. This project, undertaken with Mark Long at the Sarnoff Research Center, showcased an early endeavor to bring virtual reality technology into the consumer market, predating many of today's advancements in XR.

Her work on the project not only demonstrated the potential for immersive experiences but also laid the groundwork for the evolution of virtual reality technologies. Alexander's early contributions helped to push the boundaries of what was technologically feasible in the early '90s.
