Recent ‘Portable Garmin’s HUD’ for automobiles projects navigation information onto the windshield. The device is placed on the dashboard of the car which works wirelessly with a Bluetooth enabled smartphone. Estimated arrival time, lane assist, speed, traffic and safety camera alerts are the informations displayed. ‘Russian Hudway App’ utilizes just a smartphone (no projector) to act as HUD. It keeps track of speed, location, coming curves and hills in road, and distance by using the device accelerometer and GPS. Many aircrafts (e.g.: Embraer 190, PZL TS-11 Iskra), air buses, cars (e.g.: BMW E60, 2013 Toyota Prius) are using this device.
