Microsoft HoloLens

A self-contained, optical see-through mixed reality headset developed by Microsoft that overlays holographic content onto the real world. The HoloLens 2 features hand and eye tracking, spatial mapping, and gesture-based interaction, making it suitable for applications in accessibility, rehabilitation, education, and professional training. In low-vision research, the HoloLens has been used for magnification, contrast enhancement, navigation assistance, and collaborative training platforms. Its optical see-through design allows users to maintain awareness of their physical environment while interacting with virtual content.
