It Works !


It works ! it really works ! it's so freaking amazing.

Here's how we did it !
1. ECG pads provide raw skin conductivity / electrical activity as analogue data (0-5v).
2. This is plugged into the Arduino board via 4 analogue inputs (no activity = 0v, high activity = 5v).
3. The Arduino has a program burnt to it’s EPROM  chip that filters the signals.
4. Josh trained the program by  thinking of the main Siri commands (“Call”, “Set”, “Diary” etc.) one at a time and the program where we  captured the signature brain patterns they produce.
5. The program can detect the signature patterns that indicate a certain word is being thought of. The program will  then wait for a natural ‘release’ in brain waves and assume the chain of commands is now complete and action is required.
6. The series of commands are fed to a SpeakJet speech synthesiser chip
7. The audio output of which simply plugs into the iPhone’s microphone jack.

We still can't believe it really works.

I've been doing bits of the brain training it too, and there's a video of me... lets just say I need to do some more concentrating

  1. Awesome it is! Do you guyz really mean ECG? I believe ECG is used to measure activities of the heart.
