Michael Callahan, co-founder of Ambient, demonstrates a specially developed neckband at the TI Developer Conference which intercepts nerve signals sent from his brain to his vocal chords and relays them wirelessly to a computer which then converts them into words spoken by a computerised voice.
Using the technology, Michael makes a phone call without emitting a sound. Users of the device have to specifically think about voicing words in order for it to pick them up, but it is possible to speak verbally at the same time. If this sounds incredible, just consider the future application of this technology currently being developed which could allow users to transmit "active thought" wirelessly to interrogate search engines on the internet and have information delivered right back to them. They believe this could "augment human intelligence". Pub quizzes would never be the same again.
