Cellular Phone Heads Up Display: One idea is to create a Heads-Up Display for use with cellular phones and other handheld devices. When a call comes in the display can show the caller’s name, and at other times information such as the time and weather conditions can be shown. MP3 players can also interface with the portable display to show the currently-played song. Devices in cars can interface with the display which could minimize driver inattentiveness by maximizing the time drivers spend looking at the road rather than the displays in their cars.
