Bla Bla Bla is a sound reactive app. The students make even the slightest sound and the image on the screen changes. Most of the images are faces and when you make a sound the face changes, grows or expands. The louder or more intense the sound the greater the change.
Some of my students are working on vocalizing for a turn in response to a question. They can see right away when they have made a sound by looking at the reaction on the screen. The feedback is immediate and a powerful reinforcer.
The description in iTunes says "This App is a little selection of an exercise called “Parametric Mask”. The exercise is a part of a one-day workshop held in December 2010 at the design department of IUAV of Venice and in February 2011 at the ISIA of Urbino"
For what ever reason it was created I am glad they did because the students (and staff!) have been having a great time with this app. It is sensitive enough to register and react to even the softest of sounds ensuring that every student can be successful, and you should see their faces when they make it work!
