stick talk by sungjun cha from korea

This device helps you communicate with people who have hearing difficulties and who are visually handicapped, even if you don't know how to read Braille and sign language. If a person whom you talk to is deaf, speak to the device then it will show what you said on the display. If a user of this device is deaf, the user easily can express his/her thoughts, even if the other doesn’t know sign language, by writing sentences on the palm using the stick, then it will sense what you are writing and either display the text or speak. This function allows conversation to be possible even between the deaf and the blind.
