Method and means for telecommunications by deaf persons utilizing a small hand held communications device
First Claim
1. A method for telecommunications particularly usable by deaf persons from a sending telephone to a remote receiving location utilizing a small hand held communications device attachable with respect to the sending telephone having a DTMF keypad, comprising the steps of:
- a) spelling a word letter-by letter with one keystroke per letter by utilizing the DTMF keypad on the sending telephone;
b) displaying the word letter-by-letter in numerical DTMF keypad code on the visual display means of the hand held communications device;
c) entering of a completed word signal on the DTMF keypad after completion of said spelling of the word letter-by-letter in numerical DTMF keypad code;
transmitting of the displayed numerical DTMF keypad code, responsive to said entering of a completed word signal, to a remotely located electronic databank having a dictionary of words with their associated numerical DTMF keypad codes stored therein;
e) matching of the transmitted numerical DTMF keypad code with respect to at least one of the words of the dictionary at a remote receiving location, the words of the dictionary for each specific numerical DTMF keyboard code being ordered according to frequency of usage thereof;
f) sending back by a remote receiving location of the most frequently used matching word for display upon the visual display means;
g) entering of a match signal on the DTMF keypad to determine whether the displayed word is the correct matching word for the DTMF keypad code originally entered at the sending telephone, said entering of a match signal including possible signals of a positive match and a negative match;
h) transmitting of a next word signal to the remotely located electronic databank responsive to a negative match signal;
i) sending back by a remote receiving location of the next most frequently used matching word for display upon the visual display means responsive to a negative match signal;
j) entering of a next match signal on the DTMF keypad to determine whether the next displayed word is the correct matching word for the DTMF keypad code originally entered at the sending telephone, said entering of a next match signal including possible specification of a positive next match and a negative next match;
k) repeating of the steps of said transmitting of a next word signal by a small hand held communication device, said sending back of the next most frequently used matching word by a remote receiving location and said entering of a next match signal responsive to a negative next match signal by the user;
l) storing of a displayed word in digital format responsive to a positive match signal by a small hand held communication device; and
m) transmitting of at least one displayed word of a message in digital format by a small hand held communication device to a remote receiving location.

Abstract
A telecommunications device adapted to be positioned between the sending telephone and the line connection thereof or attachable with respect to a sending telephone by way of an audio coupling wherein the DTMF (Digital Tone Multiple Frequency) keypad of the Touch-Tone telephone is utilized to spell words on a visual display device of the communications device which can be used in combination with a packet network telecommunications system having access nodes with word guessing capability wherein the word is spelled letter-by-letter and is compared against a dictionary of words having the DTMF keypad code. The code is displayed on the screen initially with the word then being telecommunicated to a remote electronic database dictionary which guesses the most frequently used word and displays it on the display screen of the hand held device. The so-chosen word can be indicated as a positive match wherein it is stored for transmission or as a negative match wherein the next most frequently used word matching that DTMF keypad code is provided by the remote electronic dictionary for display on the visual display screen. A message is created in this fashion word-by-word and is then transmitted through a telephone line interface to a remotely located receiving location wherein reception can be in any conventional manner or can be through another similarly positioned hand held communication device associated with a receiving telephone.
