  • Lets say games start utilizing the 50GB capacity of Blu-ray discs. Is that really something you would want to download, or keep ripped to the (non-upgradable) hard drive?
  • I would like to play some of the 2.5D games such as DooM and several Build engine games - blasting away cardboard cut-outs could be fun. I'd love to play MDK too, using head tracking to aim in sniper mode like it was meant to be :D Skipping ahead …
  • I don't think it would work, and in practice might be more detrimental than anything. When you're accelerating in a car, your head is actually moving, and you sense the position and orientation of your head relative to your body. Making the camera v…
  • (Quote) A magnetometer and an accelerometer can give you full orientation data that doesn't drift - which is absolutely necessary if you want a stable way to decouple head orientation from the torso.
  • Sweet! I loved Shadow Warrior, Blood, Quake2 and MDK from that era of FPSs (ok, MDK was 3rd person).

  • I do think an additional sensor would be beneficial, though it would need to at least include a magnetometer, but might as well throw in a gyro as well - which essentially makes it the same device found inside the Rift. Also, it could be a simple st…
  • I think standing can be practical if you limit the user to standing on the spot, such as with a foot-based directional controller similar to the wii balance board experiments discussed elsewhere in these forums. Unless Sixense/Razer releases a new …
  • Those totally look like coils on top, and there seems to be a wire that runs to them.
  • There's some substantial differences between the way a coil senses a magnetic field, and the way a magnetometer does. The most obvious is that unlike a magnetometer, a coil cannot sense a static magnetic field, that's why all commercial/consumer mag…
  • There's research claiming that VR can help with phobias and social anxiety. This is a big deal because it's something a LOT of people suffer from. However, for many of the hikikomori, the related schizoid personality disorder and those with autism/a…
  • I don't remember exactly where I read it, but Palmer stated they have no plans of selling the tracker as a standalone device any more.
  • (Quote) I have nothing of value to add to this thread, but that comment made me lol. :lol:
  • While he's certainly entitled to his opinions, there are far too many inaccuracies about how the various devices work in his article. I read about 3/4 of it and couldn't be assed to finish it.
  • I had considered the possibility of using an IMU for dead reckoning in conjunction with an optical system for positional verification/correction before. The problem is ensuring that the errors can remain low enough between optical corrections, other…
  • (Quote) The Raspberry Pi is a cheap "single board computer" that uses an ARM-based processor. It's mainly a hobbyist/educational product. How does it relate to the Rift? It doesn't, except for both of them being electronic I suppose.
  • (Quote) The internals don't look that different to you, sure. But what about all those other parts? The machines that build PCBs don't care if they're making a 4 layer single board computer, or say a 4 layer motion tracking board. You load the app…
  • Jumping on the Balance Board while not being able to see it is definitely a bad idea. I'd be much more concerned about breaking my ankle (or something worse) than breaking the board. At any rate, and as it has already been pointed out, being able to…
  • You can find more details on his work here: http://www.mtbs3d.com/phpBB/viewtopic.php?f=138&t=15623 It's very impressive stuff.
  • (Quote) Stereo sprites seem like they would strike a good balance between performance and quality, especially for particles. Fauna could probably benefit too - obviously not as pretty as rendering it at high-quality 3D, but likely a lot better than…
  • @jsyblade Perhaps you hit the wrong button? I've seen quite a few ideas mentioned on this forum, so I doubt yours would have been deleted unless you were being uncivil.
  • There's no reliable way to do positional tracking with the current sensor on its own. While in theory, integrating subsequent accelerometer readings (one of the sensors used in the IMU) would enable you to calculate position, in practice there are e…
  • Besides cranking up the resolution, of similar importance is significantly increasing the refresh rate - unless you don't mind motion blurring. Even if we had super high-res and fast refresh displays, eye tracking for selective detail would be a mus…
  • (Quote) When you divide 19,200 by 50 (which was the refresh rate) you get 384 - the horizontal resolution of the VB. In some ways, the tech was sort of like modern laser scanning displays. While you could do some slick stuff with a scanning mirror…
  • Very cool that this is showing promise in a VR environment, aabel. Looking forwards to hearing your thoughts on this as your work progresses. :)
  • (Quote) Now that I think of it, I guess the depth map-less method is essentially the same thing, it's just a different way of "encoding" the incoming rays.
  • I think I can see how using a concave surface might be beneficial in terms of reducing errors, but I would imagine that determining a point in the surface relative to the viewport would require higher precision than if it was a flat surface. As for…
  • If you want to understand why we experience this phenomena, I highly recommend that you read Michael Abrash's presentation from this past GDC. You can find the transcript here: http://www.roadtovr.com/2013/03/31/gdc-2013-michael-abrash-virtual-real…
  • First of all, great work, Pyry!! I seem to vaguely recall that scene, so maybe I had been aware of your work before and forgot? :oops: I'm a bit surprised that view synthesis is more efficient on a spherical surface rather than a flat one, particu…
  • (Quote) Because at best those solutions can only offer 3DOF (if that). 6DOF is not possible, or at least not in a practical way.
  • (Quote) You would only be able to move within the confines of the cube, but as I mentioned, you could have multiple cubes butted up against each other, so you could move from one cube to the next. Theoretically, you could fill the entire area with …
