Some intersting potential for a new midi controller could be possible after some reseach and development carried out by the Karlsruhe Institute of Technology into creating mobile technology which reads the users lips. A development of this could be to create a midi expression interface?
Current applications highlighted are communication in silent environments or where the phone user may disrupt other users and the transmission of confidnetial or sensitive information – not to mention “having a quiet word” in public.
