Eye tracking for 3D holographic displays

3D displays represent an exciting new field for human-machine interactions and the research groups we represent have invested significant effort into developing holographic 3D display technologies. Unlike traditional systems, these do not operate using stereoscopy, allowing them to completely mimic a 3D scene.

The primary downside of current holographic systems is the trade-off between field of view and eyebox. Eyebox here represents the volume in which the eye can move while still seeing an image. In practical terms, this means that3Dholographic projectors must be fixed to the head using a headset.

Our aim in this project is to link the 3D displays we have developed to the user using an eye tracker. The eye tracker will be used to follow the user in 3D space and to inform the adjustable optics in our projector routing the beam towards the user.

This will enable us to massively increase the effective eyebox without compromising field of view. If done, this will allow3D holographic projectors to be included in a room with users able to move freely within the room while still seeing the same 3D scene.
