What is interesting about the Sony HMZT3 is the ways in which Sony is slowly evolving it's consumer HMD . And where it fits in the consumer arena.
The HMZT 3 will release in limited quantities later this year , I first learnt of it's coming in July at the New York Sony building whilst discussing HMDs with the staff , there was a total lack of HMZT 2s .. I was told they had been withdrawn and they were waiting for the next one... the HMZT 3 ..
The HMZT 1 was my first HMD , I mark it's coming as the beginning of the modern consumer HMD revolution. I owned 3 , nay 4 counting a replacement for one unit. As we all know comfort , sweetspot ,optical and lack of portability issues really tempered the wow of the 750 inch cinema screen.
The HMZT 2 took a little weight off , but did not really improve on the original to the point where people were posting youtube videos of their granny allegedly using it ( like some prototype VR units I could mention) .
The OLED colours and black reproduction were gorgeous and ideal for light gaming as well as 3D film viewing. It was just that you could not see the whole screen or use the device for long, or indeed move your head like you need to when you wear a HMD or indeed with a headtracker and have that image maintain fidelity corner pixel to corner pixel.
The first HMD to approach that was the LCOS based smd ST1080 . With a 100 inch 1080p res screen. That amount of detail made the pictures it produced look far more detailed than the HMZT series.
The first HMD to achieve a clear corner pixel to corner pixel experience was the Cinemizer OLED HMD.. with a 40 inch display.
Optically a wide field of view hmd , with a high magnification even when it is an OLED display throws up sweetspot issues .
Further 720p native seems to be the limit of Sony's OLED technology . At this level of magnification through the optics you will see some visible pixels , nothing like that on the Rift though.
With the HMZT3 Sony have learned lessons of wide field of view hmds causing nausea and sweetspot issues . The HMZT3 will offer the ability to reduce the "screen size" .
In practice we do this with software on the Rift all the time , it is completely untrue to think all Rift games are displayed using the entire FOV. Using the Tridef Beta can for instance give a "screen size" or FOV that looks like a distant flat screen , in cases less than other hmds..
Further innovations include a battery pack and wireless streaming. and you can connect your phones and tablets through MHL to HDMI .. which silly Endgadget journalists you can do with the previous versions too .. as well as the Rift , Cinemizer OLED , smd ST1080 and every other HMD that uses HDMI...
However far from being the Sony HMD equivalent of a Walkman , i.e. truly compact , the HMZT 3 is around the same size or in the same league of bulkiness as it's predecessor.
Headphone tech continues to improve with each HMZT HMD.
What you see is that Sony see the market for HMDs as experimental and limited , thus the changes are iterative , a tiny 10g shaved off the weight allegedly..
And most fascinating of all this latest consumer HMD from Sony shows the designers not even batting an eyelid over the hype regarding so called consumer versions of prototype VR displays.
Sony then like other HMD manufacturers is going to gently move the HMD forward , without inflating the VR hype bubble ... after all that's what Oculus is for...
Will I buy a HMZT 3 .. considering it will be around £999 here and arrive late in November in the UK ,if before Christmas .. I don't know .. it will be interesting to try out at shows
But the ergonomics really kill it for me , your HMD should be a pair of shades ..
So then the HMZT 3 reveals the real world limitations of current OLED HMD tech. At 720p Sony is still mitigating optical , sweetspot ,fitting and weight issues..
At this stage we should expect native 1080p and true portability requires a weight of around 180g ... the smd ST1080 and Cinemizer OLED more than have this covered and with Zeiss headtracking... there are so many applications...
More when I get hold of one ...
