The virtual reality headset formerly known as Project Morpheus ships this week, and Sony has recently updated its PlayStation VR FAQ to warn that bright lights, mirrors or other shiny surfaces within view of the PlayStation camera can muck up its ability to track the motions of PSVR users.

This is important for devs who plan to demo PSVR games, and Sony says it can happen because PSVR's tracking system relies on the PlayStation camera being able to pinpoint and track the brightly-colored LEDs on the PSVR headset, PlayStation Move controllers or the PS4 DualShock gamepad.

Gamasutra editor-in-chief Kris Graft was one of many members of the press who recently noted that the PlayStation VR tracking system is significantly limited, likely due to the fact that it relies on years-old technology (the Move controllers, for example, were first released in 2010.) Nevertheless, Graft encouraged developers not to ignore Sony's entry into the VR market -- just to be aware of its limits, and design around them.
