After Sony launched the PlayStation 4 About six months ago, the company introduced us to Project Morpheus. Though the PS4 was around before we ever heard of Morpheus, Sony has said that it has been working on Morpheus for several years, so it should come as no surprise that the platform has influenced certain aspects of the PS4.
According to Jed Ashforth, Senior Designer at Sony Computer Entertainment Europe "The tracking light… it was our department that said we need that on," and "It was for tracking for VR."
"And when all these things were coming out six months ago and everyone was going 'it's reflecting in my TV,' we were going 'oh no' because we couldn't tell anyone what it was for."
So to all of you guys frustrated about that blue light, you may start appreciate it after all.
