Holo-this, holo-that. Holograms are so bamboozling that the term often gets used colloquially to mean ‘fancy-looking 3D image’, but holograms are actually a very specific and interesting method for capturing light field scenes which have some real advantages over other methods of displaying 3D imagery. RealView claims to be using real holography to solve a major problem inherent to AR and VR headsets of today, the vergence-accommodation conflict. Our favorite holo-skeptic, Oliver Kreylos, examines what we know about the company’s approach so far.
RealView recently announced plans to turn their previous desktop holographic display tech into the HOLOSCOPE augmented reality headset. This new headset is similar to Magic Leap‘s AR efforts in two big ways: one, it aims to address the issue of vergence-accommodation conflict inherent in current VR headsets such as Oculus Rift or Vive, and AR headsets such as Microsoft’s HoloLens; and two, we know almost no details about it. Here they explain vergence-accommodation conflict:
Note that there is a mistake around the 1:00 minute mark: while it is true that the image will be blurry, it will only split if the headset is not configured correctly. Specifically, that will not happen with HoloLens when the viewer’s inter-pupillary distance is dialed in correctly.
Unlike pretty much everybody else using the holo- prefix or throwing the term “hologram” around, RealView vehemently claims their display is based on honest-to-goodness real interference-pattern based holograms, of the computer-generated variety. To get this out of the way: yes, that stuff actually exists. Here is a Nature article about the HoloVideo system created at MIT Media Lab.
