COMPACT HEADS-UP DISPLAY SYSTEM

摘要

A portable heads-up display device for deployment on the dashboard of a vehicle. The device includes a housing suitable for mounting to or placing on a surface, and containing system electronics and a projector. A curved high-gain reflective screen disposed on the housing rearward of the projector receives an image produced by the projector, and reflects that image to a semi-transparent curved combiner disposed near the front of the housing. A virtual image appears at the combiner that has a focal point in the distance beyond the combiner. One or more rear-facing sensors and the control electronics detect hand gestures by the driver, which controls the operation of the device in displaying images. The device mounts to a dashboard via a conformable and foot that adapts to the shape of the dashboard. Magnetic coupling between the housing and a puck element held in the foot facilitates removal and replacement of the device.
