Short for Mobile Augmented Reality Applications
MARA is a Nokia research project that uses camera-equipped mobile devices
for sensor-based, video see-through mobile Augmented Reality
. The MARA prototype application uses accelerometers in all three axes to determine orientation, a tilt compensated compass for heading, and GPS for positioning. If the absolute location and orientation of a camera
is known, along with the properties of the lens
, it’s possible to determine exactly what parts of the scene are viewed by the camera.
