The piSight HMD is light (weighing less than 2 pounds), stable, comfortable, and adjustable to an individual’s head and eye shape, but Sensics still wants to make the technology more lightweight and efficient. Sensics also offers customized systems that track a user’s eye movements, which help vision researchers learn which images or objects in a scene hold a user’s interest, and also offers a video see-through solution for applications in which users need to see the virtual world and reality simultaneously. With the addition of the SoniWing, the user’s entire body moves within the virtual environment, allowing greater freedom than systems restricted to head motion, and the environment responds realistically to the user’s location and movements. When used with the piSight, InterSense Inc.’s SoniWing tracks user movements, employing technology similar to some video gaming systems. Some versions of the piSight work with motion trackers, which eliminate the need for a joystick and, instead, follow the user’s movement realistically. By coordinating head and joystick movements, the user flies or coasts up, down, forward, or sideways. With the piSight, virtual surroundings appear in the viewfinder and respond to head movements. “Astronauts wearing a piSight will feel just like they are experiencing the world from Robonaut’s perspective, due to the full field-of-view, which is an exciting advance for the NASA robotics program,” says Brown. The operator sees through Robonaut’s “eyes” and controls its movements, working safely from a distance. The Sensics piSight HMD, essentially a high-tech viewfinder, offers an additional panoramic, high-resolution camera array that allows remote control and telepresence, immersing the HMD operator in the robot’s workspace in real time. A follow-on Phase II SBIR project culminated with Sensics delivering the piSight HMD to Johnson Space Center in February 2008, after delivering the prototype the year before. Baltimore-based Sensics created an HMD with a wide FOV, using a patented optical design to combine several tiled images into a high-resolution, three-dimensional panorama. Lawrence Brown, Sensics Inc., received a NASA Small Business Innovation Research (SBIR) program award in 2003, and began Phase I of their FOV interface for NASA’s Robonaut, which also included development of a wide FOV camera. In addition to a wider FOV, NASA also desired higher resolution in a head-mounted display (HMD) with the added ability to capture and display video.įounded by former Johns Hopkins University optics researcher, Dr. Because of the narrow FOV, NASA decided to reach out to the private sector for assistance. Johnson robotics engineer, Darby Magruder, explained that the 40-degree field-of-view (FOV) in initial robotic prototypes provided very narrow tunnel vision, which posed difficulties for Robonaut operators trying to see the robot’s surroundings. One of the problems Robonaut developers encountered was that the robot’s interface offered an extremely limited field of vision. Robot Systems Technology Branch engineers at Johnson Space Center created the remotely controlled Robonaut for use as an additional “set of hands” in extravehicular activities (EVAs) and to allow exploration of environments that would be too dangerous or difficult for humans.
