Would love to see this IRL. What are the strongest use cases for tech like this, @dfattal7?

@rrhoover we all have our own favorite application but on top of the lists are Education (keeping learners engaged and increasing retention), Retail (leveraging that emotional connection to Lightfield content), Hospitality (hotel room tablet) and Medical training.

@dfattal7 @rrhoover once these are in our computers and phones and we have good enough 3D it will revolutionize video chat. The experience of presence with a 3D display cannot be beat except by IRL

@rrhoover @drewbeck yes, and in our experience more useful than video chat is 3D screen sharing for productivity, something we are actively working on...

@rrhoover @dfattal7 whoa very cool. Are you working on 3D desktop interfaces, then? Or are the screens 2D but floating in 3D space 🤔

@rrhoover @drewbeck those are flat screens that project different views of the content in different directions of space, so your eyes pick up a different image and you perceive depth this way. You can already use the Lume Pad as a 3D interface to your Unity editor for instance.

I’m David Fattal, co-founder and CEO of Leia. We’re excited to be on Product Hunt today! We developed the Lightfield technology for the Lume Pad because we wanted to connect users emotionally to the digital world. Our screens make memories more present. Connections, more human. Life, richer. Our 10.8 inch screen powers the first 3D Lightfield tablet. You can enjoy creations both in 2D and 3D with no glasses. It's all possible through our developments in nanotechnology (our DLB layer) and Computer Vision. We already support the creative tools you rely upon while adding even more to elevate your creations. Between our SDK, the Leia App suite onboard the Lume Pad, and our own Lightfield Studio video software we take all the guesswork out of converting existing 2D content to gorgeous 3D. In short, we made the Lume Pad for creators like you. I’ll be monitoring Product Hunt throughout the day and am looking forward to answering some questions!

Hello, I am interested by this tech for 3D gamedev. - the site states "4-View Lightfield". Does this means it displays 4 discrete viewpoints (which contradicts what the videos shows) or a f(x, y, φ, θ) that looks continuous and gives a window-like effect, including when you move towards/away from the screen? - if I use OpenGL + a Luma API directly, what should I provide? Several buffers in orthogonal projection for light emitted in several directions? - does it need head tracking to look good? Can I get head tracking data to render relevant views?

@lilian_gimenez thx for the questions. The device outputs 4 discrete views (actually an array of 4x4 but we typically use 4x1 in landscape and 1x4 in portrait). If you want to use openGL you can use our Android SDK to do most of the work for you. You would generate 4 images simultaneously from different virtual cameras and "interlace" the 4 images into a composite image that will be sent to screen. You would just control the position of the virtual cameras (which also control the amount of perceived depth), the plane of focus, and add effects such as synthetic depth of field to make the content feel more continuous at view transitions. No we do not rely on head tracking, but we do offer a tracking API (leveraging the device front ToF sensor) for developers who want to extend the natural view zone of the display. hope this helps !

@lilian_gimenez @dfattal7 Thank you for your answers. Is the 1x4/4x1 views only for rendering less views or does the display have a per-axis 3D vs resolution tradeoff? I will stop here but I would need to read the docs and experiment with it to fully satisfy my curiosity.

@lilian_gimenez we render 4 views vs 16 to save computational time, the display is physically able to output the full 4x4 array. The Pad started to ship if you order today it will be at your home in 72h :) for the doc check www.leialoft.com. Please feel free to ask as many questions as you want this is our passion

@lilian_gimenez @dfattal7 I read the docs. You all made it easy to support this display. I have a few extra questions: - does having 4x4 views helps with accommodation cues (to avoid the discomfort from the mismatch between perceived depth and focus still at screen plane)? - can I render an arbitrary light field without helper functions then call leiaViewInterlace? There is room for artistic effects beyond "normal" 3D.

@lilian_gimenez @dfattal7 4x4 views spaced with one full inter ocular distance (6.5cm) is not enough to help with accommodation (you need at least 2x2 or 3x3 views per pupil size ~ 5mm ). However the natural depth rendered by the display is a few inches inside+outside of screen plane so unlike VR or glasses-based 3D the vergence-accommodation conflict is not an issue in our case. On using the interlacing step independently of the view generation I asked my team let me get back to you...
