The HELIUM3D display will be autostereoscopic - that is viewers will not need to wear special glasses to view 3D. The other key issues for the display are:
- Support for multiple viewers
- Allow for viewer freedom of movement
- Motion parallax to viewers
- High brightness and wide colour gamut
- High resolution
- Large depth-of-field
- 2D/3D switch-ability
- Large uninterrupted viewing field and potential for large screen size
- Conventional high-loss LCD front screen replaced by high-efficiency transparent optics
- High-accuracy viewer tracking
- Direct image projection to the eyes of viewers
- Support for intuitive 3D user interaction
- Viewer gesture/interaction tracking in near and far fields
- Capability for user to work within the image 'volume'
- Non-intrusive interaction technology (no data gloves)
- Interactive applications based on pupil tracker output
- User-centred design, ensuring that future products are “fit for purpose” in terms of perception and usability
- Potentially inexpensive
- Long laser life
- Low power consumption
One important advantage of the HELIUM3D display will be that it is potentially extremely versatile. For example, it has the inherent ability to switch from standard resolution to high-resolution 3D without any hardware modification. Also, when viewers are outside the usable 3D viewing region, the system will adapt and viewers will see the image in 2D.
The display will be relatively inexpensive when mass produced and utilises low power lasers. The inherent tracking capability will be used to support natural modalities of interaction (e.g. gesture and gaze).
