ARM: Mobile Graphics Will Surpass PlayStation 4, Xbox One In 2017 (venturebeat.com)
AmiMoJo writes with a report from Venturebeat on the state (and predicted future) of mobile-device graphics: ARM, the technology design company responsible for the popular ARM CPU architecture, is preparing for another big leap in computational power for smartphones and tablets. ARM ecosystem director Nizar Romdan explained that the chips that his company creates with partners like Nvidia, Samsung, and Texas Instruments will generate visuals on par with and then surpass what you get from the PlayStation 4 and Xbox One consoles by the end of 2017. PS4 can compute around 1.84 TFLOPS (tera FLOPS), with mobile chips approaching 2 TFLOPS by the last quarter of 2017. Romdan points out that virtual reality eliminates that form factor difference. Wearing a headset on your face is the same if you're tethered to a PC or using a phone.
...The problem is that we perceive distance by two mechanisms - focus and convergence. Everybody has fixed convergence - nobody has fixed the focusing issue....
There is a fix for the focusing issue, but it is quite expensive: Holography. You feed each eye with the same light waves that they would have received if they had been looking at the objects being depicted--two virtual images. I suspect this technology is too expensive for today's market, but it is the only good solution to the problem.
