Background InformationPatients with considerable neuromotor disabilites–Cerebral palsyDifficulties speakingCauses frustrationCurrent technology not desirableLong-time ambition for improved devicehttp://img.dailymail.co.uk/i/pix/2007/10_01/KThorpeEastNews0710_468x726.jpgII. Problem StatementTo design a device that allows people with communicative disabilities but motor functions to speak and express emotion with their voice. The device must provide immediate output, and it must be intuitive and accurate.III. Client RequirementsDevice for those who cannot speakPhonetics basedFaster, more expressive means of communication“Bridge the gap” for people with difficulty speakingIV. User CharacteristicsCerebral PalsyLiterateNormal cognitive functionDifficulty with oromotor controlDifficulty with fine motor controlParalyzed diaphragmPossibly wheelchair-boundMany different levels of the severity of disabilityExamplehttp://www.youtube.com/watch?v=1xrMCutzHzEV.
