Zusammenfassung:A head up display arrangement is for a motor vehicle having a human driver. The arrangement includes a picture generation unit producing a light field. A light-reflective mirror reflects the light field such that the light field is visible to the driver as a virtual image. The mirror is transmissive of infrared energy. An infrared energy emitter emits infrared energy through the mirror such that the infrared energy is reflected off of a face of the driver. An infrared camera detects the reflected infrared energy after the reflected infrared energy passes through the mirror a second time.
