Hands-on: Microsofts HoloLens is flat-out magical
2015: the year that sci-fi becomes real.
For the second time in as many months I feel like I've taken a step into the world of science fictionand for the second time in as many months, it's Microsoft who put me there.
After locking away all my recording instruments and switching to the almost prehistoric pen and paper, I had a tantalizingly brief experience of Microsoft's HoloLens system, a headset that creates a fusion of virtual images and the real world. While production HoloLens systems will be self-contained and cord-free, the developer units we used had a large compute unit worn on a neck strap and an umbilical cord for power. Production hardware will automatically measure the interpupillary distance and calibrate itself accordingly; the dev kits need this to be measured manually and punched in. The dev kits were also heavy, unwieldy, fragile, and didn't really fit on or around my glasses, making them uncomfortable to boot.
But even with this clumsy hardware, the experience was nothing short of magical.
Microsoft calls it holography. I'm not sure if it really is (Wired describes HoloLens's "light engine" has having a "grating," so perhaps it really is using interference patterns to reconstruct light fields rather than providing the same simple stereoscopic 3D found in VR systems), but this is a detail that only pedants will care about. (Though if it is true holography, it should solve the focus issue that many people find with existing 3D systems.)
However it works, HoloLens is an engaging and effective augmented reality system. With HoloLens I saw virtual objectsMinecraft castles, Skype windows, even the surface of Marspresented over, and spatially integrated with, the real world.
It looked for every bit like the holographic projection we saw depicted in Star Wars and Total Recall. Except that's shortchanging Microsoft's work, because these virtual objects were in fact far more convincing than the washed out, translucent message R2D2 projected, and much better than Sharon Stone's virtual tennis coach. The images were bright, saturated, and reasonably opaque, giving the virtual objects a real feeling of solidity.
