HRI is a field of study dedicated to understanding, designing, and evaluating robotic systems for use by or with humans. Interaction is communication between robot and human 

  Virtual reality (VR) technology has been highlighted recently in many industrial and biomedical fields. It has previously been applied to robotics micromanipulation, military skills in soldiers, phobia treatment, post-traumatic stress disorder, motor skill training on athletes, and surgical skill improvement. We research how to combine virtual reality technologies with human-robot interactions technologies. Since VR affords a more immersive experience than real environment, human robot interaction with VR can be used in training robotic surgery and remoting manipulator, which is safe and low-cost.
