Making a floating display

Imagine combining this display with mid air haptics like what ultraleap did using an array of transducers, so you can feel when you touch it. You could even use leap motion for hand tracking to detect interaction, though that last part may be unnecessarily overcomplicated for the interacting tracking.

[@makermac70]

Thanks for the comment. Haptics is indeed an idea that I had already thought about. Tactile interactions would definitely be great. Maybe I'll have a look at that. I briefly looked at the Leap Motion solutions (hand sensor), but they were too expensive for me.

Secure input is actually a really good idea for this, especially if you combine it with a scramble pad where digits are in a randomised sequence

[@antonliakhovitch8306]

Although, a scramble pad on a regular screen is probably good enough for almost all applications.

[@IONATVS]

@@antonliakhovitch8306Other than concerns about (1) hidden cameras/observers watching you use the pad-also a solved problem, just necessitating some other method (physical barriers, polarized filters, etc) to reduce viewing angles to just the intended one, but this may be less obtrusive than some of those, so preferable in some situations, or (2) a situation where the secure code entry issue is COMBINED with the sterilization issue. A scramble pad is still a touch screen, so can be a vector for infection.

This would be excellent to combine with those sonic arrays that provide haptic feedback by making standing waves of low/high pressure in a 3d space. (look up sonic tweezers for a sense of them). If you could create a sense of feeling at the location of the buttons, that would remove a lot of the annoyance people might have with imprecise entry that would discourage its use.

​@@paulbunyangonewild7596The "we miniaturized X, therefore we can miniaturize Y" logic is dangerous. There's subtlety. CRTs set a limit to how thin TVs could be, until we came up with an entirely new technology to replace them. Floating displays would also require an entirely new technology to make the emitter smaller than the image. You can't predict if/when a new technology will be developed. Maybe it'll be tomorrow, maybe in a few decades, and maybe we've already reached some fundamental limits. (The exception is when the theoretical basis for the device is already there, but engineering work has to be done to figure out how to manufacture it. That's why we've been able to accurately predict advancement in computer processors.)

[@boltinc2334]

The emitter can be smaller than the image if a laser array projector is used, brighter, and more controllable, can also provide enough rapid movement for 3D persistence of vision effect

[@jagmarc]

Passive light position/movement sensing is prone to ambient light interference. But when a sensor detection field is instead illuminated with pulsed light and the signal processing synchronized to the pulse's phase, that effectively plunges a lit room into darkness. It's an extra dimension of signal processing.

Security I think is a secondary nature - we've got the same kind of screens you were discussing for that, just standard screen overlays disallow seeing anything unless you are directly in front of it. All of them are completely viable applications regardless. I just might have to build something like this over the winter while I'm stuck indoors :)

the applications for this that you mentioned are a pretty big market I like it

[@SarahKchannel]

If I was to try the finger tracking, I would most likely try a 2D IR matrix sensor and some combination of TOF / distance sensor. The IR matrix should give the position on the X/Y axis, while the TOF would give the Z/touch distance.

[@makermac70]

Thanks for the suggestion. Yes, the finger tracking is really simple. For a more advanced floating display version with better resolution I would definitely need something like that. Then I might look into 3D time-of-flight cameras, which work in a way like you suggested: by illuminating the scene with a modulated light source and observing the reflected light.

[@kenjinks5465]

I have a theory: If you moved the real screen back and forth and had a sensor telling the CPU where the monitor was, you could create a cross section of a 3D object on the screen to match the position. Then with persistence of vision, the floating image would appear 3D. (going about moving the screen precisely is too much work, you got to just measure where the monitor is and update the image)

I have two silly questions: First, how do you ajust focus? Can you control visible position of your virtual screen? Second, why do you need reflector? Maybe simply place LCD directly instead reflector? In this case picture would be brighter. Or it is have something to do with focus?

[@makermac70]

1. In contrast to an optical system based on a lens, there is no real "focus" control due to the principle described above. However the quality of the reflector material greatly affects the sharpness of the formed image. 2. The reflector itself is required as a passive optical element that converges diverging light rays from the light source display to the floating image.

[@makermac70]

Thanks for the question. Interestingly, curving or generally modifying the surface of the retroreflective layer has no effect at all. You could even take a wave shape and stick the retroreflective film on it - the result would always be the same. This is due to the unusual property of reflecting light rays in exactly the same direction.

[@makermac70]

thanks... Yes, I looked at the VL53L08 which can create a 64 zone mini depth map. Very cool product and definitely worth a try if I want to improve the machine.

[@kyleeames8229]

Concerning the use of time of flight sensors to track the users finger, if the sensors are powered on separately, sampled and then depowered to prevent the laser emissions from one from interfering with the reading of the other, and a lens used to fan out the beam, the triangulation method of tracking the position of the users finger would not only be viable, it could achieve far higher resolution… the beam would first need to be columnated, because the raw output from the laser diode appears to be spread conically, then the beam could pass through an optic like a curved reflector or a cylindrical lens to fan it out.

[@makermac70]

Thanks for your thoughts on this. Sounds like it could work. However, it requires a bunch of special optical components for IR lasers, which seem expensive... but not sure. Anyway, would be a great solution if it's not more expensive than a Leap Motion hand gesture sensor.

[@kyleeames8229]

You can probably make the optics yourself. You’d just need to take care that the materials used are transparent to the IR wavelength of your sensors. A columnating optic train diagram can be found with a little online searching and a cylindrical lens is literally just a polished cylinder made of an optical material that refracts your wavelength. It’s also worth mentioning that you’re not doing holography or anything that requires the finest optics, so if a ready made version of what you need isn’t available for cheap, it can be homemade.

[@yigitrecepozdemir4073]

Can You Put A Mirror As The Reflector Film? That Way It Would Be Way More Sharp.

A mirror creates a virtual image *behind* it. The retroreflective material is what makes the "real" image in front of the device. The sharpness depends on the resolution and precision of the retroreflector cells.

[@fredashay]

Awesome! Now you just need to miniaturize it so you only see a tiny "camera eye" in the wall or surface with a large floating display.

The optics of a retroflective system like this means that you can only see the image when you can see the retroreflector "through" it. It can't be made any smaller than the display.

[@JamesHalfHorse]

Nicely done.

[@captheobbyist6434]

this is so cool. if you add more sensors, you can make a full range of input. im wondering, why is the light not projected onto the ceiling? light will keep on traveling until it meets a certain point, does the beam splitter slow down the photons so they stop at a certain point? or is it intersecting light particles? i dont really get how this works, if the beam splitter just splits the light in half... if it does split it in half, then why doesnt it appear on the wall next to it? the second question i have, can this be made more compact? if it's basically a light stopping at a certain point, can you make a tiny display and then make it appear larger with a lens? sort of like AR glasses where you can interact with it but instead it's physical if this can be made as compact as those new glasses (im talking about apple vision pro or glasses from meta), and the input will be reliably enough, it can be used commercially!

[@makermac70]

Thank you for your questions. The reason why there is no image on the wall is because it is not a projection principle. Rather, the impression of an image in space is created by the convergence of light rays. To understand this better, you might imagine that a real display would emit the same light rays at exactly this point. To make the application more compact, there are already concepts with optical elements that combine the beam splitter and the retroreflector. The design becomes much more compact, but still a box, and not really minimal.

[@darth_dan8886]

I'm surprised with the choice of the SBC for this project. LattePanda Sigma is a very impressive machine, and using it to simply drive a display feels about as wasteful as using a Raspberry Pi to blink some LEDs. Other than that - really cool project. Could see potential other sensor types being useful - but these would surely require more than just connecting to SPI to function, so probably outside the scope of this thing.

[@makermac70]

thanks, yes it may be that the SBC is a bit oversized, but I needed something with 2 HMDI outputs that could show both static and animated graphics on both screens, and as a Windows system the GUI was easy to program. What are the alternatives for something like this (other than the Pi not running Windows?)?

[@davidelang]

One thing that I am missing from the "how it works" is what changes the beam of light into something that you can see as a point. If you shine a laser, you see nothing until the beam hits an object. As you focus a light source to a point, you see nothing at the point that the light converges. With both this and your volumetric display, what is it that causes the light to appear as a point in space?

[@makermac70]

Perhaps it will help to imagine the following: If you replaced the floating image with a real display in this position, the rays would emerge from the pixels in exactly the same way. In both cases, the eye would see rays "originating" from a source. That is why we see a real image in the air. A laser, on the other hand, simply generates a single straight beam of light. To "see" the laser beam requires a scattering of particles such as fog or mist.

[@davidelang]

​@@makermac70 I'm still missing something. As I understand your description, the light rays from the display are getting bounced and go through the points in space where the display should appear, but a light source at that point would radiate it's light in every direction, the light ray passing through that point is only visible if you are directly inline with that ray I can get the light rays from the display to pass through that point in space at that angle with just a mirror, no need for the beamsplitter or fancy reflective surface. But looking at that display through the mirror won't have it appear to float in space and the viewing angle would be very narrow. The fact that the camera can pick up the display from the side shows that something very different is happening. what I'm missing is what causes the rays to fan out from the point in space where the display is. why do they fan out at all, and why not from some point closer or further from the display

[@makermac70]

A display with a normal mirror would not cause rays to converge on a point for the eye to interpret as outgoing rays. This is only possible with this principle, and you need the components discussed. The fact that the image can only be viewed at a narrow angle is a side effect that can be improved with complex techniques. For a better understanding of the principle, it would be recommended to read the linked scientific papers. See my project description.

[@roysigurdkarlsbakk3842]

I think it's worth pointing out that retro reflective foil designed for safety is purposely lousy because no one has a source of light projecting from their eyes, so if there wasn't some scattering, you would never actually see the glow. I think that's probably why you are having difficulty getting a clear image, since that is probably the purpose of most of the products you looked at. I imagine you would need something like an optics grade tetrahedral retro reflector for that crisp image.

[@AlucardNoir]

@@AS-np3yq University professors noticed GenZ didn't know how to save a file or how to navigate to where they had saved as far back as 2017. Also... Gen Z starts in 1997 and Alpha in 2013. Half of GenZ would be of working age, the oldest would be in their late 20s.

Really cool.

Have you considered the VL53L5CX three axis TOF sensor?

[@makermac70]

Thanks for the suggestion. Yes, I have seen that sensor and may try it next time. However, the "large FOV" of 65° is a bit narrow for my system (I currently have a FOV of over 80° with my 3 sensor system).

Wow. That's like totally nuts :D

[@TheShorterboy]

if you have the latte panda just get a leap motion thing for the hand stuff

[@makermac70]

Thanks for the suggestion. I actually looked at the controller first, but at over 200€ I felt it was a bit too expensive for my DIY project.
