I came across an interesting article this morning. A Japanese company called TechFirm [JP] has just released a special Twitter client for the iPad in the App Store. “Breath Bird” lets handicapped users tweet with their breath. Interesting, right? People who can’t use their fingers can still engage in the Twitter universe by simply breathing into the iPad’s mic. The way that it works is when you open the application; your timeline appears in on the left. On the right, an on-screen keyboard appears with all letters and other characters. These characters are split into five rows.

The Breath Bird application then starts to highlight each row, one at a time, from top to bottom. If the user wants to “type” a particular character, he/she can breathe into the mic of the highlighted row and make the app highlight all of the characters in that row, one after another- from left to right. Once the desired character is highlighted, the user simply breathes again and it appears in the tweet bubble. Users just have to repeat to create words that can then be posted to their Twitter in the same fashion.
