The document summarizes Microsoft HoloLens, the first holographic computer running Windows 10. It allows users to see and interact with holograms overlaid in their real-world environment. HoloLens uses sensors to track eye gaze and gestures as inputs. Holograms are projected onto the user's field of view using two nano projectors located on each side of the head and a see-through visor. Potential uses include remote instruction, 3D design, gaming, navigation, and entertainment. However, HoloLens has limitations such as a small field of view, short battery life, high cost, and risk of accidents if used improperly.

5. What is HoloLens
 HoloLens came by combining the two words “Hologram” and
“lens”.
 Microsoft HoloLens is the first holographic computer

7. Sensor :
• Sensor tracks where the wearer is looking and adjust the
display.
• Motion sensor detect wearers movement.
• Wearer can also give gesture as input, sensor enables the
tracking of user movement.
Buttons :
• On the right side buttons allow user to adjust the volume and
to control the contrast of the hologram.

9. Working of HoloLens
o Microsoft HoloLens has User Interface so it takes voice ,
gaze and gestures as input command.
o Then internal computer works on input command.
o Now for projection of hologram, HoloLens use the
HUE(head up display) method: two Nano projector located
at each side of head and semi transparent visor which
reflect the image as light on users eye.
