Learning Morse Code without Trying
From: ECN - 10/28/2016

Researchers at the Georgia Institute of Technology have developed a system
that teaches people Morse code within four hours using a series of vibrations
felt near the ear. Participants wearing Google Glass learned it without
paying attention to the signals - they played games while feeling the taps
and hearing the corresponding letters. After those few hours, they were 94
percent accurate keying a sentence that included every letter of the alphabet
and 98 percent accurate writing codes for every letter.

This is the latest chapter of passive haptic learning (PHL) studies at
Georgia Tech. The same method - using vibrations while participants aren't
paying attention - has taught people braille, how to play the piano, and
improved hand sensation for those with partial spinal cord injury.
