The Facts Of Light

Eymerce’s Brand of Vision

The human eye functions much like a camera- both devices gather, focus and transmit light through a lens to create an image of the surrounding environment.

Vision is the consequence of these light rays stimulating the eye’s visual pathway – the nerve signals traveling from each eye along the optic nerves and other nerve fibers to the back of the brain where vision is sensed and images are interpreted.

In the absence of light rays there is no vision; there are no images for the brain to sense. Here is where Eymerce started its scientific investigation – from an absence of light.

What is light and how do we describe its characteristics? The core question led us to an amazing discovery!

Strategic Question: In the presence of the light how would you describe the set of all things one can ever see at any point in time and space? Light Field science was a clue.

Faraday (1846) was the first to interpreted light as a “field” similar to his earlier description of a magnetic field. Then Gershun (1936) famously coined the term ‘light field’ to geometrically describe the 3D orientation of discrete rays of light in space along an x,y,z axis. Adelson (1991) described the direction of a ray of light as its 2D magnitude or its radiance and created the 5D orientation and direction of a ray of light referring to it as the 5D plenoptic function. Today’s graphic artist has the ability to create light describe light as 7D adding time and wavelength to describe the plenoptic function.

 

The 5D Plenoptic Function of a conceptual ray of light

We focused on brightness since we could control that with our LED screen technology. The brightness or luminosity of light is generally described as radiance but now there are many different ways to characterize radiance. We   focused on spectral radiance in its role to create amazing imagery in the negative space – the z axis. Spectral radiance is the radiance of a surface per unit frequency or wavelength depending on whether the spectrum is taken as a function of frequency or of wavelength. These are directional quantities we have engineered into our design to create the field of light emitted from our LED screen to the eye to be interpreted as amazing imagery.

Radiance became is a particularly useful concept in Eymerce’s technology development lexicon because it indicates how much of the power emitted by our LED screen surface will be received by an optical system – our eyes – looking at that screen surface from a specified angle of view.

The Light Field created by Eymerce’s infinite solid angles of light

In our case, the solid angle of interest is the solid angle subtended by the optical system’s entrance of the human eye. In our design spectral radiance became a guiding indicator of how “real” our images would appear. Our LED screen configuration at our optimized diode density creates infinite solid angles in any position including the periphery for our observing gamers to experience the 7D optic function a field of light that our Stadeon screen will create.

Our screen technology’s spectral radiance heightens the visual awareness of our imagery and as we moved our viewers up the dimensional hierarchy from 3D through 5D to 7D imagery. We created an Elevated Reality that amazes the viewer.

The Technology

They exhausted all the projection options through a number of immersive projects and screen configurations and came to the conclusion that gamers needed future display technology to address two important unsolved questions: Am I there – solving the “place illusion” of VR; and Is it real – solving the “plausibility illusion” of VR.

Taylor and Lowe recognized the potential experience that “presence” offered VR gamers and turned to a new way to reinvent an old technology for display: LED – Light Emitting Diode – screens at a higher resolution and frame rates. Taylor recalls, “What if the light for VR content originates from the screen itself and that light surrounds you to create the illusion of 3D?” To organize and to finance the answers to this question Eymerce, LLC was formed in November 2016.

Over the next six months supported by seed capital from an outside investor and under Lowe’s leadership, the Eymerce protocol project evolved from an idea to the creation of an open source platform for VR content distribution, an SDK to support Indie game producers and complimenting patented LED screen technology with patent pending screen formats accompanied by patent pending display hardware designs.

With the hardware and software designs in place, the Eymerce team imagined an LED screen display format and technology that would take full advantage of VR’s promise of an immersive “presence.” We call it Stadeon.

Every gamer that experiences Stadeon will be amazed, but we must be realistic about how accessible, how affordable and how quickly we attract the avid gamers in the US.

We know that over 220 million Americans play games on TVs, Consoles, PC and mobile devices, so why not Stadeon! Console gamers spend an average of six hours a week playing games; Stadeon will replace a lot of those hours. Back Stadeon and let us AMAZE THE WORLD!

There is nothing new about a LED – light emitting diode – a British scientist discovered the electroluminescence phenomenon in 1907 and a Russian invented the first LED in 1927. The early invention had little practical use until experimentation exciting different crystalline substrates yielded the first visible spectrum – red- in 1962. More color ranges, energy efficiency and brightness improvements in 1972 paved the way for its use in optical fiber telecommunications.

Similar to Moore’s law the white light output efficiency of LED has improved exponentially since the 1960’s – doubling every 36 months – and is generally attributed to the parallel development of other semiconductor technology and advancements in optics and material science. Automobile head lights, traffic lights, stadium score boards, roadside billboards aggregate the LED’s in a tight pixel pitch screen format presenting familiar display uses of the LED technology today. But our LED and concept advancements have taken the screen technology in a different direction and with amazing visual display results. We formed Eymerce to distribute our content and Stadeon to display the content.

Richard Taylor created a new way to think about LED as a new display form factor – a three-dimensional display or actually creating a third dimension of display for virtual reality content. The technology behind this new approach is patented using a common cathode rather than the traditional anode approach to drive the electrical current of an LED screen more efficiently – producing less heat – and a global clock to drive the potential for the ocular illusion of 3D. This combination of a common cathode / global clock is the core technology for more patented technology that improves the color contrast, brightness, reliability, and spatial presentation of our LED screen display.

Our screen is made up of a number of 3” x 4” boards populated with small LED’s spaced at a millimeter apart that are combined into a cabinet that form the light image emitting face of the screen. These cabinets are attached to electronic components on the back of the board that drive the screen imagery. The cabinets are connected to a proprietary setup of computer hardware that controls the distribution of display content.

The wrap around format of the screen is also patent pending and creates a spatial and intuitive presence. Our format transports the viewer into a special quality of attention that psychologists refer to as “flow” where the viewer is completely cognitively absorbed in an activity associated with their viewing experience. Photo of the display format We have created more peripheral vision sensitivity to color and to spatial presence with our wrap around screen technology. The anatomy of the eye is complex, but as the retina spreads across the interior concave surface of the inner eye you see less color and experience less spatial reference, because the brightness of the light through the lens of the eye is reduced in the outer reaches of the retina. Our screen technology emits uniform light resolution at a constant brightness around the screen that allows you to see the full dynamic range of light in three dimensions. That phenomenon does not happen in the world we see from light emitted by the sun. This uniformity of brightness and color from any oblique angle of the screen to the eye stimulates more photo sensory activity and improves color and spatial reference thereby elevating the appearance of the imagery in your peripheral vision.

In effect, you can see with more acuity positioned in Stadeon than you can in real life. Stadeon creates an elevated reality that heightens your ability to experience our content and enjoy something you have never experienced. The potential for “presence” beyond there and real are interesting future projects we will fund. We think our current technology gives us a head start in social presence with the designs and configuration of our Stadeon facilities. We are particularly interested in emotional presence and the role empathy can play to actually simulate and change behavior. We think our technology is a step in the right direction in the evolution of embodiment presence and active presence as well. These are all future potential dimensions of presence that will create change in the way the world perceives and experiences our elevated reality.
