By: Matt Oppenheim

Matt Oppenheim has developed a radio that speaks to an Android smartphone. He
designed the gadget to help the visually impaired learn the layout of a new

connected them to a Nexus One Android phone. He added the audio-enhanced
touch sensors to the radio. When a control is touched, the phone plays an
audio tag describing the function.
