Humans communicate primarily in a verbal manner, while dogs rely more on visual cues. While this can make communication between the two species challenging at the best of times, it's particularly difficult when the human is unable to see the dog – as is the case with blind people and their guide dogs. As a result, it may not always be possible for owners to know when their guide dogs are stressed. An experimental new harness, however, may be able to help.
NASA astronaut Terry Virts, aboard the International Space Station (ISS), and ESA telerobotics specialist André Schiele, in the Netherlands, made space history this week with the first telerobotic "handshake" between space and Earth. Using special force feedback joysticks that acquire force data and create the sensation of pressure, Virts and Schiele brought the agencies closer to allowing astronauts in remote locations to naturally and safely control robotic devices and perform potentially dangerous or otherwise impossible tasks.
