Right now I'm learning stenography and I hope to incorporate features like steno order and shorthand techniques into the device in an attempt to create a portable device that can keep up with higher typing speeds. I LOVE shopping the new arrivals at Adafruit. Because at the end of it I can't use all of them right? It is compatible with all Windows PC and Mac computers and does not require any special drivers to program it. At this point the switches may take more room than anything else. I hope you'll tell me either way. The experience with the chording keyboard has been good so far. The ergonomics of this device have been abandoned in favor of a highly portable keyboard. Thus, in the case of quadriplegia wherein the handicapped person may only have the use of a few toes or facial muscles, the keyboard may have a rather large, built-in vocabulary to enable that person to communicate with others using words built upon keyboard chording. However, the motivation behind this is still the same. However, there are three main types of switches represented by different color codes, and each performs differently. for (int i = 0; i < 7; i++){ boolean buttonState = !digitalRead(pinkyButton + i); if (buttonState){ buttons[i] = HIGH; }else{ buttons[i] = LOW; } } for (int i = 0; i < 7; i++){ if (buttons[i]){ return HIGH; } } return LOW; }, void typingChord(){ while (acquiringPresses){ for (int i = 0; i < 7; i++){ if (buttons[i] == HIGH){ latchingButtons[i] = HIGH; } } acquiringPresses = checkButtonArray(); } }, void sendKeyPress(){ for (int i = 0; i < 7; i++){ if (latchingButtons[i] == HIGH){ chordValue = chordValue + customPower(2, i); } } Serial1.write(keySwitch(chordValue)); }, int customPower(int functionBase, int functionExponent){ int functionResult = 1; for (int i = 0; i < functionExponent; i++){ functionResult = functionResult * functionBase; } return functionResult;
