TechCrunch reporting:

A Japanese company called TechFirm [JP] has just a released a very special (and free) Twitter client for the iPad in the App Store [iTunes, bilingual English and Japanese]: “Breath Bird” lets people who can’t use their fingers and have problems speaking post to Twitter by breathing into the iPad’s mic.

The keyboard has a letter grid that highlights each row in turn. Mic input then confirms a row and starts the highlight moving horizontally. A second input then confirms an individual character or command (such as ‘Tweet’ and ‘Delete’). Innovative and clever use of tech.
