1. A system for directing projections within a vehicle, the system comprising:
a digital light processing (DLP) projector for producing a projected image;
a projection directing module in optical communication with the DLP projector for directing the projected image to a predetermined location, wherein the projection directing module further includes a liquid crystal lens (LCL) in optical communication with the DLP projector, and wherein the projection directing module further includes a spatial light modulator (SLM) in optical communication with the LCL;
a projection surface upon which the projected image is projected; and
a controller in electrical communication with the DLP projector, the LCL, and the SLM, wherein the controller is programmed to:
configure the projection directing module to direct the projected image to a projection region of the projection surface at least by applying a grating to the SLM based at least in part on an angle between the SLM and the projection region and setting a focal length of the LCL based at least in part on a location of the projection region; and
project the projected image on the projection region using the DLP projector and the projection directing module.

10. A method for directing projections within a vehicle, the method comprising:
configuring a projection directing module to direct a projected image to one of a plurality of projection regions on a vehicle windscreen, wherein the projection directing module includes a liquid crystal lens (LCL) and a spatial light modulator (SLM), wherein the SLM is in optical communication with the LCL and the vehicle windscreen, wherein the SLM is in electrical communication with a controller, and wherein configuring the projection directing module to direct the projected image includes applying a grating to the SLM based at least in part on an angle between the SLM and the one of the plurality of projection regions and setting a focal length of the LCL based at least in part on a location of the one of the plurality of projection regions; and
projecting an image on the one of the plurality of projection regions using a digital light processing (DLP) projector and the projection directing module, wherein the DLP projector is in optical communication with the projection directing module.

15. A system for directing projections within a vehicle, the system comprising:
a digital light processing (DLP) projector for producing a projected image;
a projection directing module in optical communication with the projector, wherein the projection directing module includes:
a liquid crystal lens (LCL) in optical communication with the DLP projector; and
a spatial light modulator (SLM), wherein the SLM is in optical communication with the liquid crystal lens;
a projection surface upon which the projected image is projected; and
a controller in electrical communication with the DLP projector and the LCL and SLM of the projection directing module, wherein the controller is programmed to:
determine a selected projection region of a plurality of projection regions of a vehicle windscreen;
set a focal length of the LCL based at least in part on a distance between the LCL and the selected projection region;
apply a grating to the SLM based at least in part on an angle between the SLM and the selected projection region; and
project the projected image on the selected projection region using the projector and the projection directing module.
