Developed method for teaching Morse code in four hours through Google Glass




Google Glass can make learning Morse code much easier because researchers have developed a system that teaches the code within four hours using a series of vibrations felt close to the ear.

Morse code is a method of transmitting text information in which the letters are represented by combinations of sound signals of the long and short light or.

Participants learned using Google Glass heedless signals - they played games while feeling the taps and hear the corresponding letters.

After those few hours, they were 94 percent accurate typing a phrase that includes all the letters of the alphabet and 98 percent of precise writing codes for each letter, according to the researchers.

"Does this new study that people will run to learn Morse code? Probably not," said lead researcher Thad Starner, a professor at the Georgia Institute of Technology.

"This shows that PHL (passive haptic learning) lowers the barrier to learn methods of text input - something we need to smartwatches and any text input that does not require you to look to your device or keyboard," he said in a Starner Georgia Tech statement.

This is the last chapter of passive touch studies learning at Georgia Tech.

The same method - through vibrations while participants are not paying attention - has taught people in braille, how to play the piano and a better hand feel of people with partial spinal cord injury.

In the current study, the team decided to use glass as it has both a built-Tapper (bone conduction transducer glass) speaker.

In the study, participants played a game of taps while feeling the vibration between the temple and ear.

Faucets represented the dots and dashes of Morse code and passive "taught" to users through their tactile senses - even while they were distracted by the game.

The taps were created when researchers sent a very low frequency signal to the speaker system glass. Because they played very slowly, the sound was felt as a vibration.

Half of the study participants considered the taps vibration and a voice prompt for each corresponding letter. The other half - the control group - felt no taps to help them learn.

Participants were tested throughout the study about their knowledge of Morse code and ability to write. After less than four hours to feel each letter, everyone is challenged to write the alphabet in Morse code in a final test.

The control group was accurate only half the time. Those who felt passive signals were almost perfect.
