The Georgia Institute of Technology (Georgia Tech) has been experimenting with several methods of passive haptic learning (PHL). In this test using Google Glass, they taught subjects Morse code in four hours. The method: having the subjects play a game while feeling vibration taps between their temple and ear that represented the dots and dashes of Morse code. This passively taught them code through their tactile senses, even while they were distracted by the game. The test group received a voice prompt for each corresponding letter, while the control group did not. When tested on the Morse alphabet, the test group was nearly perfect, while the control group was accurate only about half the time. The vibrations were generated in Google Glass through a lower than 15 Hz signal played very slowly and below hearing range through the bone-conduction transducer. “Does this new study mean that people will rush out to learn Morse code? Probably not,” said Georgia Tech professor Thad Starner. “It shows that PHL lowers the barrier to learn text-entry methods — something we need for smartwatches and any text-entry that doesn’t require you to look at your device or keyboard.” Georgia Tech News  Hat tip to former Northern Ireland Editor Toni Bunting
