    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.

      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.

    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.

    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.

    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.

      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
      @kyleeames8229 Місяць тому

      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.

    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
      @makermac70  2 місяці тому +2

      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.

    11:07 The Latte Panda has a built in Arduino Leonardo which basically can also act as a Human Interface Device (HID) which you could program directly to enter value like a keyboard or use it like a mouse.

    • @makermac70
      @makermac70  Місяць тому

      Thanks - yes, the Leonardo could be used as HID to act like an external keyboard. I tried to use it for basic sensor processing at first, but it somehow did not work at all. After some unsuccessful tweaking, I decided to use the external Arduino Nano.

    The technology isn't new. back in the 90's in Europe i often went to the local arcade hall and while my eyes always went to the pinball machines, i noticed a machine with 3d floating people in a black space with "no screen" It was the game "Time traveler" from Sega and was showing the gameplay via a laserdisc, like Dragens lair. It looked amazing and wierd to look at a black hole instead of a screen. Also remembering it was often broken. Nice sidenote, the reason for me going to that arcadehall so much was the build to scale battlestar Galactica from 1978 with lights flashing in the landing bays ;-)

    I wonder what would happen if you used a lenticular display as the light source. Are we closer to that princess Layla Star Wars moment? As one projection has a narrow field of view then what happens if you put multiple projections Into the same space using different camera angles of a 3d image? Pseudo 3d?

  • @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
      @makermac70  2 місяці тому +2

      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?)?

  • @glenbertram7652
    @glenbertram7652 2 місяці тому +2

    I may not be fully understanding this, but could you swap out tablet display for your volumetric one? Would that not create multiple in-air focal planes, and thus, have a stereoscopic effect for both your eyes?

    • @Matthew_Raymond
      @Matthew_Raymond 2 місяці тому +2

      So, you mean take a holographic display where objects appear to be inside it and use this technique to reposition them in mid air? I suspect the focal distance might be inverted, though, and it would basically render inside-out. Might make more sense to create a new hybrid display.

  • @captheobbyist6434
    @captheobbyist6434 24 дні тому

    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
      @makermac70  24 дні тому

      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.

    Wouldn't it be really easy to "shoulder surf" these displays? If you know where all the buttons are you know what's being pressed. I guess you could randomize the layout but that would hurt it in situations where muscle memory is important.

    Very ingenious project! 🙌
    If you let me make a suggestion: what do you think about using a video camera instead of sensors? Obviously, software (AI?) would be needed to process the images and interface with the desired control. I believe that with this system it would be possible to develop more complex screens (with more options, shapes and graphics) and start thinking about being able to manipulate three-dimensional images...

    • @makermac70
      @makermac70  Місяць тому

      Thanks for the constructive feedback. I wanted to keep the effort and cost to a minimum, so I didn't use expensive 3D cameras like LeapMotion. Displaying and manipulating 3D objects has been suggested several times and is a great idea that I will definitely look into.

  • @TheMNWolf
    @TheMNWolf Місяць тому

    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.

    • @makermac70
      @makermac70  Місяць тому

      Thanks for the comment. I also found a company that sells retroreflective material for professional use like this. However, it's too expensive for DIY purposes. If you are interested, search for "Nippon Carbide RF-A".
