[Philip Lelyveld comment. This is one way to back-door consumer acceptance - headphones plus...]
Avegant’s Glyph is a head mounted display which is embedded into a pair of over-ear headphones. The Glyph’s headphone band can be swiveled down to position what the company calls a “virtual retinal display” in front of the user’s eyes. With a field of view around 45 degrees, the Glyph doesn’t quite fall into the category of ‘VR headset’, but its unique display technology and portable form-factor make the Glyph worth tracking. The company has said previously that their display technology, which utilizes a micro-mirror array, could be adapted to a wider field of view for use with VR.
