100 thoughts on “The Next Step to a Holodeck”

  2. To program it you start by using the shape of the 3d model to create a "hitbox". Then you associate a "touch" texture to the visual texture .Finaly ,to determine were the person is in the game world, you need to wear a suit that have control point on key places like they do in 3d animated movie … You can also use ai like the kinect , but it won't nessecerly be precise … Now it is just a question of "Top-down" approch.

  3. What if the transducer box was just a bubble-like glove around your hand? You wouldn't need a whole room full of them, and they'd be easier to program and change.

  4. You should do a video on how media's portrayal of minorities over the decades have impacted the views held by them and about them. Possibly in sci show psych.

  5. I imagine the star trek writers 40 years ago be like: let's make everything so stupidly advanced that nobody will ever archive this in real life. And now look what we have archived.

  6. I have an idea, and it sounds pretty crazy, but it might work. You would be suspended in the air wearing something that resembles an iron man suit. It would allow you to move freely, until you hit an object in game (such as the floor with your feet, or a wall with your hand.) Then it would lock the joins that allow you to move in that direction. This would allow you to move around in game, without actually walking around in real life, but it would also allow you to interact with physical objects in the game.

  7. I think it will be technologically "easier" relatively speaking to put a human in a simulator directly interfaced with the brain, á la Matrix, rather than somehow get a "Holodeck" working. At this point in time, we're not even sure if it's physically possible to 1. make holograms appear anywhere we want them to appear, and 2. Make holograms actually touchable with force fields like in Star Trek. We do however know that given the time, we will probably be able to figure out the brain and how to interface with it, since it's basically a matter of controlling chemistry and electricity.

  8. my bet is on a brain-machine interface(skip the middle man) but that tech still has so far to come. This will likely fill the gap while that happens.

  9. i see a future where this touch sensation gets so real, ai gets so real, holographic simulation gets so real, you wouldn't need a flesh & blood girlfriend anymore

  10. So we pay for ad free YouTubeRed so that money supports our artists and then they go and shove ads down our throat. Nice work

  11. just thought of this: are there things that would never happen in any alternate realities?

    the only suggestion I came up with is different realities merging together, but that might happen anyway

  12. I use VR as a design tool for theme parks. I've tested 2 models of these ultrasonic haptic devices. It is very cool tech, but they have a very very long way to go before they actually feel like real objects. The "pressure" it take to "break through" the perceived surface is basically zero. You have to feel the surface and stop yourself from moving your hand further. It's not convincing yet. But there is a lot of money going into research on these systems, so maybe…

  13. We use VR at work. I'm an architect and we use VR so our clients can walk through a virtual version of their building before it's built.

  14. there are gloves that simulate touch

  15. I wonder which is harder: Simulating touch or simulating acoustics?

    Acoustic simulation needs some pretty demanding computation if you want it accurate to the scene geometry. It's demanding enough that Epic Games has only just started putting pre-computed non-directional versions of it into their games in the last couple of years (I think the talk I watched used Gears of War 4 (which I haven't played) as their demonstration). Kind of like how we were doing pre-computed radiosity lighting back in the days of Quake.

  16. The real incentive for inventing things like this isn't gaming, it's mechanical engineering. There is a use in seeing your machines etc. before building them to avoid errors that cost millions. But what is the additional use of additionally being able to feel your design without building it?

  17. I dislike the cutting away of any breath or slight silence, that you normally hear in a conversation. It make me feel stressed. Also, it makes it hard to follow, as there is no time to digest what is being said. Therefor I would like to suggest a more natural edit so I can enjoy the very interesting content of the scishow video's.

  18. Remember Hanks facial hair. It made him so sassy ? ITS NO SHAVE NOVEMBER HANK, DONT SHAVE! LET SASSY HANK OUT??

  19. I think just like how we have self-driving cars before flying cars simply due to practicality and technology, we'll probably have virtual reality that you plug your brain into before we have any kind of Star Trek holodeck. I don't think it'll be too long before we all have microchips in our brains that let us connect wirelessly to the internet and plug ourselves directly into virtual worlds Matrix-style. And I think if we can do that, it'll be way easier (and cheaper) than trying to figure out a holodeck situation.

  20. You do know that ultrasound is dangerous right? Is there anybody on board doing any research or do you just read the zeitgeist and spew.

    Another thumbs down. Get your act together.

  21. One of the most important ones- allow training for full contact fighting without the danger of taking full force blows! This could seriously lengthen professional fighter careers and allow more people to safely spar opponents to even see if they'd like training for the real thing.

  22. I have been thinking of a helmet which puts you in some sort of a dream, where electric signals are send to your brain like it would be your eyes, ears, hands and feet.Also your body can be some kind of paralized so you won't move, allowing for making open world simulations where you won't be afraid of hitting a wall or walking over your computer and stuff. But I am worried how this could affect someone's brain like causing tumors and stuff. Still I think it could work

  23. I think you are wrong: next step is brain implants.
    It took a decade, you said, to barely make touchable VR things.

    What about taste? What about gravity (eardrum) feel, smell, real running, etc.
    What about the space required for all these gear?
    How many more decades to make these happen? And how much electricity would be required to make all these run, how much space will people need to make all these machinery run?
    Pretty much, implants are scaleable, but not creating a special device for each sense.

    It's just much easier, and less expensive, and involves less cables and less space for the end users, to just plug something into their brains.
    Yes, VR is the future, but not through gimmicks and hardware: it will be through implants.
    There is already the eyesight that has been 'decoded' and we can make fake 'eyes' or stream directly to the brain bitmaps.
    Now we need to do the same for the other senses.

  24. Humanity just needs to survive long enough to invent the holodeck and then everyone will be too busy playing with it to go to war or contribute to global warming.

  25. To be honest, as much as I love Star Trek, the holodeck concept seemed like a ridiculous waste of space and energy.
    A starship has a limited amount of space, so why waste several cubic meters of it when you can just plug yourself into a virtual simulator like the kind in the Matrix movies?
    Instead of having one or two massive holodecks on board, every personal quarters could have its own VR plug-in device.

  26. How about lowering the price of a VR headset ?
    So i dont have to pay $999 for something that only has 2 working games…

  27. Why not just use a simple electrode system to shock the body in such a way that it feels like you’re touching something?

  28. Does this mean that, finally, after long last, we really are one step closer to smell-o-vision?!


  29. Please take this as a suggestion. Anti-reflective lenses for your glasses would improve viewer's experience.
    Brilliant job of explaining science.

  30. Yeah, it'll be interesting to see how they design it so it doesn't hurt animals, and kids/those of us with super-hearing-dog-ears who can hear dog collars and dog whistles.
