Is this that $3000 expensive thing that can barely handle a small area of a Minecraft map?
BAD field of view compared to adverts
I guess it is a fabulous technologic revolution (need to perform some details,cost,tools,etc.). But I am wondering the real benefit of these. (check out "Black mirror" series)
Technically correct, but hugely disingenuous. The field of view is limited by fundamental physical limitations of the diffraction-grating waveguide used for the view-through optics (the diffraction grating is holographically patterned, hence the 'holo' in 'Hololens') With Crown Glass or optical plastic, which has an index of refraction peaking at 1.6/1.7, you're limited to a 30 to 35° FoV. Why not just use materials with a higher refractive index for a greater FoV? because you hit a limit in refractive index with Diamond of around 2.5, which nets you a bit above 50° FoV.While some Microsoft representatives have talked about the limited FOV allowing you to keep your peripheral vision clear, Harris indicated it was necessary "because of cost and battery-life," considerations.
There's effectively no prospect for Hololens to increase it's FoV with the current optics, or with any optics either on the market or yet demonstrated in prototype form*. The limit is physical rather than financial: either magical new high-refractive-index bulk materials suddenly are developed (i.e. nope) or visible-band wide-bandwidth metamaterials are developed (allowing a whole new class of lens).
*I'm sure someone is going to pipe up about Magic Leap here. They have made a lot of wild claims, a lot of vague claims, and the single video purportedly of an actual device has an FoV of just below 40°. Magic Leap gets to sit in the corner with the "Vaporware" hat until they can actually back up their extraordinary claims with some extraordinary results.
Or you could just sit really close to a big monitor to give a larger FOV.
Perhaps no ones thought of this before? :-)
