Geeky Gadgets 10:44 am Using an Arduino Mega microcontroller together with some custom 3D printer parts and international team of researchers have developed a new concept called GuideBand, taking the form of an arm mounted device that physically guides players within VR. “This device looks a bit like an external fixation apparatus for securing broken bones. It straps onto the user’s arm and has three motors controlled by an Arduino Mega via TB6612FNG motor drivers. The first motor moves the device’s gantry radially around the user’s arm. The second motor adjusts the angle of attack, offset perpendicularly from the forearm. The third motor acts as a winch and pulls a cable attached to a strap on the user’s arm.”
