After less than four hours of feeling every letter, everyone was challenged to type the alphabet in Morse code in a final test. The control group was accurate only half the time.

The type of the signal tone can be changed from "Characters", and Morse code sounds randomly from 44 types including at least 2 alphabets, numbers and symbols at maximum.

While the telegraph had been around in idea and rudimentary form, Morse devised a way to use electricity for sending a series of codes signaling letters of the alphabet.

Morse had converted the alphabet into a system of dots and dashes to send telegraph messages over land lines. European nations revised the code in 1851 and it gained widespread acceptance.
