Enhancing the Visual Experience of AR & VR
RGB light engines (e.g. LED, LCD, DLP, LCoS) in modern displays output a colour co-ordinate to recreate the effect that a natural image has on the eye’s red, green and blue cone cells. However, RGB approaches don’t account for an additional retinal photoreceptor – melanopsin – which also influences the visual experience (brightness, circadian cycles, pupil size, alert- ness, mood).
4Sight is an image rendering framework which uses four degrees of freedom (red, green, cyan, violet – RGCV) to control the stimulation of melanopsin independently of cone cells.
In near-eye displays, users are acutely sensitive to image quality. A 4sight light engine could enable closer replication of the natural world and sophisticated control of viewing experience.
- “Visual salt”: Control of melanopsin produces more vivid and natural looking images without distorting chromaticity or luminance.
- Circadian effects: “Night-time” viewing settings without distorted colour balance.
- Power consumption: A cyan primary can reduce the required luminance from a, typically less efficient, deep- blue primary.
- Dynamic range: Enhance perceived brightness in dark conditions without increasing luminance.
- Colour palette: Accurate rendering of blues & greens beyond UHDTV standards (rec. 2020), utilise the full gamut of the latest cinematic cameras.
We are seeking licensing and co- development partners to evaluate this technology and create a demonstrator 4Sight light engine for a near-eye display or immersive visual art installation.
