Method and apparatus of using Morse code input combined with text-to-speech output for eyes-free, quiet, discreet and partially hands-free mobile text messaging

摘要

The invention describes a method for sending and receiving text messages by a correspondent to/from another party using a mobile phone or other mobile device where the correspondent inputs the required text to the device in Morse code without the use of the correspondent's vision (eyes) and the correspondent's voice, while requiring a minimal employment of only one of the correspondent's hands or arms. The Morse code consists of only the symbols “dot” and “dash” and can be entered “blindly” with an input device having the barest minimum amount of sensors. The invented method of texting is being facilitated by audio guidance produced by the mobile device's text-to-speech synthesizer and played to the correspondent (possibly privately) through an audio reproduction system attached, connected to, or built into the mobile device. The invented method of mobile text messaging does not require the correspondent's vision, thus freeing the correspondent's eyes for other activities. By not requiring the correspondent's spoken voice the invention allows discreet and private mobile text messaging in the presence of other individuals, as well as making it possible to communicate in noisy environments where using voice recognition to enter text would not be viable. By reducing the employment of the correspondent's hands/arms to only a limited use of a single hand/arm, this invention can address text messaging scenarios where hands are needed for other tasks, for instance walking or driving a vehicle.
