The low-cost haptic interface could be used to provide finger-level control of a Robonaut 2 hand. Simpler grasp gestures can also be detected to simply indicate that a robot should grasp an object. The developed interface will also provide greater access for planning and training of EVAs, and could provide a more intuitive interface for ground personnel to operate and supervise robots. Haptic feedback from the developed ungrounded haptic interface will increase a user's level of presence relative to other ungrounded interfaces. Because of its low cost, the developed haptic interface could also be used as a common hardware interface to recruit academic and industry researchers to rally around and solve NASA grand challenges, because they could all afford and use the same human-robot interface hardware. These devices could also be used in NASA outreach/STEM activities within science installations that will allow young and old space enthusiasts to interact with NASA training simulations in the same manner as NASA personnel.
Non-NASA applications of this research include creating more immersive and natural interactions in virtual reality, as well as video games. The Oculus Rift Head Mounted Display (HMD) has brought a resurgence in Virtual Reality (VR) because of its low cost. Our technology could provide a powerful haptic counterpart to their HMD. The grasp sensing developed in this project will create the ability to roughly measure hand pose and grasp gestures that could also be used to provide greater immersion for VR and video games. There are also applications for controlling telerobots for handling hazardous materials (e.g., for toxic cleanup or handling nuclear waste) or for interacting in hazardous environments (e.g., oil well maintenance at the ocean bottom or underwater search and rescue). It is also possible that our developed haptic interface could be used to interface with a remote care-giving robot, for in-home elder care by a remote caregiver.
