Driver queries using wheel-constrained finger pointing and 3-D head-up display visual feedback

With the capability of fast, wireless communication, combined with cloud and location-based services, modern drivers can potentially access a wide variety of information about their automobile's environment. This paper presents a system for information query by the driver by using a simple pointing mechanism, combined with visual feedback in the form of a 3-D Head-up Display (3D-HUD). Because of its 3-D properties, the HUD can also be used for Augmented Reality (AR) as it allows physical elements in the driver's field of view to be annotated with computer graphics. The combination of simple natural user input tailored for the constraints of the driver with a see-thru 3D-HUD allows drivers to query information while minimizing visual and manual distraction.
